A study by CEE Professor Lydia Bourouiba and Professor John Bush of mathematics shows that coughs and sneezes have associated gas clouds that keep their potentially infectious droplets aloft over much greater distances than previously realized. The study finds the smaller droplets that emerge in a cough or sneeze may travel five to 200 times further than they would if those droplets simply moved as groups of unconnected particles — which is what previous estimates had assumed. The tendency of these droplets to stay airborne, re-suspended by gas clouds, means that ventilation systems may be more prone to transmitting potentially infectious particles than had been suspected. With this in mind, architects and engineers may want to re-examine the design of workplaces and hospitals, or air circulation on airplanes, to reduce the chances of airborne pathogens being transmitted among people.

Professor Philip Gschwend describes the “legacy of problems buried in our environment” that often arise as side effects of products — such as PCBs and catalytic converters — designed to solve already existing problems. His research group has developed inexpensive sheets of polyethylene that can be placed in mud or water to soak up chemicals and measure their availability as they move through the environment. But the real answer, he says, is to prevent such problems in the first place by involving environmental chemists at the outset of materials and chemicals design.

Marine cyanobacteria — tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2 — are primary engines of Earth’s biogeochemical and nutrient cycles. They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain. Now postdoc Steven Biller and Professor Sallie (Penny) Chisholm have discovered another dimension of the outsized role played by these tiny cells: The cyanobacteria continually produce and release vesicles, spherical packages containing carbon and other nutrients that can serve as food parcels for marine organisms. The vesicles also contain DNA, and they may even act as decoys to deflect viruses. Read a news story.

Roughly a billion people worldwide live without safe drinking water and each year millions are sickened by waterborne diseases, a condition CEE Senior Lecturer Susan Murcott hopes to improve through dissemination of household drinking water treatment and safe storage systems, a cluster of innovative technologies she has helped invent and promote: one used by about 800,000 people in Guatemala; another that removes pathogens and clarifies turbidity in Ghanaian drinking water used by over 100,000 people; and a third, a filter sold in Nepal to screen out arsenic and bacteria, which has so far reached 350,000 people. All three projects make use of locally available materials and the local workforce to create jobs in manufacturing and sales. Many CEE Masters of Engineering students, School of Engineering, DUSP and Sloan students have worked with Murcott on these projects, which were showcased at the Expo Bid Symposium in October in Dubai and will be honored during the World Expo 2020 in Dubai.

Hidden risk in supply chains: Analytical study finds no link between expenditures and supply-chain risk
December 17, 2013
A new study by CEE Professor David Simchi-Levi helps explain why risk in a complex supply-chain network often remains hidden. There’s no correlation between the total amount a manufacturer spends with a supplier and the profit loss it would incur if that supply were suddenly interrupted. This counterintuitive finding defies a basic business tenet that equates the greatest supply-chain risk with suppliers of highest annual expenditure. When applied to Ford Motor Company’s supply chain, the quantitative analysis shows that the supply firms whose disruption would inflict the greatest blow to Ford’s profits are those that provide the manufacturer with relatively low-cost components.

Coral reefs, the most biodiverse ecosystems in the world’s oceans, are declining because of bleaching and disease. But little is known about the microscale interactions between the pathogens that cause disease and the weakened coral. Now CEE’s Professor Roman Stocker, postdoc Melissa Garren and grad student Kwangmin Son have identified one mechanism by which pathogenic bacteria identify their prey: The stressed coral produce up to five times more of a sulfurous compound called DMSP. The abundant DMSP appears to serve as a clarion call, inciting the pathogen cells, which sense the amplified chemical and charge in for attack, changing their swimming direction and speed as they home in on the weakened coral.

Could the path to a more sustainable future be paved in concrete? Researchers at MIT’s Concrete Sustainability Hub (CSHub) certainly think so. By investigating cement and concrete from the nanoscale up and considering its full life cycle, they are working to reduce the energy footprint of the world’s most common building material. “The per-unit weight impact of concrete on CO2 levels is low; but since each person on the planet consumes 1 cubic yard of concrete each year, the aggregate impact is substantial,” said Franz-Josef Ulm, faculty director of the CSHub and the George Macomber Professor of civil and environmental engineering. Indeed, the production of cement powder, the primary ingredient of concrete, accounts for 5 to 10 percent of global CO2 production annually. Read a story.

Motivated by aquatic flowers, Professors Pedro Reis (CEE and MechE) and John Bush (Mathematics) recently designed an upside-down floral pipette whose petals grab liquid as they close. This mechanism was inspired by the behavior of water lilies, which float at the surface of ponds or lakes while anchored to the floor. As water rises, hydrostatic and surface tension forces act to bend and eventually close the lily’s petals, thereby preventing water from flooding in. Reis's upside-down flower pipette does the opposite, grabbing water as it’s pulled up, thereby reversing the role of gravity. (This work was published in Soft Matter online Oct. 14, 2010.) The researchers calculated the optimal petal size for capturing a small sip of liquid and then fabricated synthetic flowers through casting, each of which is about 35 millimeters wide — about the size of a small dandelion. This liquid grabber design is now being used by Spanish José Andrés, one of the world’s leading chefs, as a means of serving a palate-cleansing liquid between courses.

Once again, the annual Parsons Lab Halloween party and pumpkin carving contest was a shrieking success, attended by 125 CEE students, staff, faculty, friends and families, who used knives and other sharp instruments to stab, carve and otherwise mutilate about 65 pumpkins — some of which emerged as works of art. The jack-o-lanterns were judged by graduate students Fatima Hussain and Kyle Peet, and technical assistant Becky Schilling. Graduate student Jennifer Wehof won first prize for her carving of a scary tree; second prize went to graduate student Mason Stahl for a hot air balloon. Five pumpkins with faces inspired by Pablo Picasso’s cubist work tied for third place, the creations of postdoctoral associate Gabriel Juarez and graduate students Jane Chui, Alison Hoyt, Thomas Petersen and David Whittleston. CEE gives a special thanks to Sheila Frankel, associate director of Parsons Lab, and James Long, administrative assistant, who planned and organized the Oct. 25 party, and to graduate student Ruby Fu for photographing the event.

As public-health officials continue to fight malaria in sub-Saharan Africa, researchers are trying to predict how climate change will impact the disease, which infected an estimated 219 million people in 2010. But projections have been hampered by wide variation in rainfall predictions for the region and lack of a malaria-transmission model that adequately describes the effects of local rainfall on mosquitos. A new study by Professor Elfatih Eltahir and graduate student Teresa Yamana solves this problem by combining a model of malaria transmission with global forecasts for temperature and rainfall. They found that although the capacity for malaria transmission will change in some areas of West Africa, overall infection rates are not likely to increase. Climate change by itself is not likely to make the situation worse. Read a news release.

Public discussion and private sector involvement on Hyperloop could speed up the usual design process, writes Saurabh Amin
August 14, 2013
In an opinion piece for CNN, Professor Saurabh Amin likens Elon Musk's request for public comment on the design of the Hyperloop — an ambitious high-speed transportation system — to open source web programming, saying that collective design could speed up the process. "But just as today's open source product designs on the web have benefited and improved from the collective effort of programmers, so has Musk decided to confront the design bottleneck by opening up the design process to the general public — anyone and everyone who cares."

In an epidemic or a bioterrorist attack, the response of government officials could range from a drastic restriction of mobility to simple suggestions that people remain at home. Deciding to institute any measure would require officials to weigh the costs and benefits of action, but at present there’s little data to guide them. However, a new study by Professor Ruben Juanes, graduate student Christos Nicolaides and research associate Luis Cueto-Felgueroso shows that even moderate measures of mobility restriction would be effective in controlling contagion in densely populated areas with highly interconnected road and transit networks. The researchers called the difference between infection rates in the two scenarios the “price of anarchy,” a concept from game theory that’s frequently used as a metric in studies of transportation networks.

Understanding the strength of a mussel’s underwater attachments could enable better glues and biomedical interfaces
July 29, 2013
Unlike barnacles, which cement themselves tightly to surfaces, the bivalves called mussels dangle more loosely, attached by a collection of fine filaments known as byssus threads. This approach lets the creatures drift further out into the water, where they can absorb nutrients. Despite the outwardly thin and fragile appearance of these threads, it turns out that in the dynamic, sloshing environment of waves and currents they can withstand impact forces that are nine times greater than the forces exerted by stretching in only one direction. The secret to these tiny natural bungee cords has now been unraveled by research scientist Zhao Qin and professor of civil and environmental engineering Markus Buehler. Their findings appeared last week in the journal Nature Communications. Read a news story.

Tiny ocean plants, or phytoplankton, were long thought to be passive drifters in the sea — unable to defy even the weakest currents, or travel by their own volition. In recent decades, research has shown that many species of these unicellular microorganisms can swim, and do so to optimize light exposure, avoid predators or move closer to others of their kind. Now Professor Roman Stocker, William Durham Ph.D. ’12 and grad student Michael Barry have shown that the motility of phytoplankton also helps them determine their fate in ocean turbulence. Rather than acting to distribute them evenly — as physics would demand of small particles mixed into a fluid — the individual vortices that make up ocean turbulence are like social mixers for phytoplankton, bringing similar cells into close proximity, potentially enhancing sexual reproduction and other ecologically desirable activities.

Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria have multiple flagella that rotate as a bundle to move the cell forward. These cells turn somewhat acrobatically by unbundling their flagella, causing the cell to tumble, reorient and strike out in another direction. But 90 percent of motile marine bacteria have only a single rigid flagellum. These microbes change direction with a sideways “flick” of their flagellum — a unique swimming stroke first documented in 2011 whose mechanism has been a mystery. Now, using high-speed video to record individual swimming bacteria at up to 1,000 frames per second, Professor Roman Stocker, Kwangmin Son and Jeffrey Guasto show that the flick occurs when the so-called “hook,” a flexible rod connecting the flagellum to the cell’s internal motor, buckles during forward swims. The drag on the cell head caused by the water’s resistance combines with the opposing thrust force from the rotating flagellum to compress the hook, causing it to buckle and flick the cell into a 90-degree reorientation.

A poster by Gabriel Juarez, postdoctoral associate in Professor Roman Stocker's Environmental Microfluidics Group, won first prize in the MIT “Postdocs Share Their Science” event held June 18 in Morss Hall. Juarez’s poster, “Biophysics of Microbial Oil Degradation,” which Stocker describes as "elegant and insightful" was selected from 44 entries, netting Juarez a new iPad. The abstract said: “Many species of oil-degrading bacteria are equipped with flagella that enable the cells to swim and actively pursue nutrient gradients in their local surroundings. We are interested in understanding the role of motility on the encounter rate and attachment dynamics of microbes with oil droplets. We are investigating the swimming behavior and attachment dynamics at the microbe level using dedicated microfluidic devices and observing with phase contrast and epifluorescent microscopy.”

Researchers working to design new materials that are durable, lightweight and environmentally sustainable are increasingly looking to natural composites, like bone, for inspiration. Bone is strong and tough because its two constituent materials, soft collagen protein and stiff hydroxyapatite mineral, are arranged in complex hierarchical patterns that change at every scale of the composite, from the micro up to the macro. While researchers have come up with hierarchical structures in the design of new materials, going from a computer model to the production of physical artifacts has been a persistent challenge. Now Markus Buehler and team have developed an approach that allows them to turn their designs into reality. In just a few hours, they can move directly from a multiscale computer model of a synthetic material to the creation of physical samples. Read a news story.

As part of the "broader impacts" component of a National Science Foundation (NSF) research grant, two 1C undergrads and an alumna — junior Linda Seymour, sophomore Shante Stowell and Elise Hens '12 — are working with CEE lecturer Ari Epstein to make a series of three podcasts about the research of Professors Martin Polz and Scott Manalis (biological engineering) covered by the grant. Episode 1: World’s Tiniest Diving Board (8.5 minutes) tells how the researchers are using microfluidics technology and a miniature diving board to measure the mass of microbes to learn how much a microbe grows before it splits apart to replicate. Episode 2 will focus on the recent findings that microbes exhibit social cooperation, episode 3 on the ways scientists communicate their research findings — formally and informally — within the scientific community and to the public, and the final episode will summarize the research supported by the grant. Epstein said he hopes that other CEE principal investigators will want to incorporate similar projects in their NSF proposals. "It's a relatively low-cost and interesting opportunity for outreach that provides a nice educational experience for the undergraduates," said Epstein. The podcast series, “Measuring Marine Microbes,” is available on Soundcloud.

Professor Oral Buyukozturk of CEE and Professor William Freeman of electrical engineering and computer science (EECS) and the Computer Science and Artificial Intelligence Laboratory (CSAIL) are principal investigators (PIs) on an $8 million, five-year collaborative research project funded by Shell. The project builds on the concept of previous research on MIT’s Green Building, which has been instrumented with a sensor network that monitors the building’s response to disturbances and allowed researchers to determine its fundamental frequencies and ambient vibrations. With the new grant, through representative laboratory models and implementation studies on the real structure, the PIs will create a wireless version of the monitoring system, develop pattern recognition/motion magnification algorithms and build 3-D computational models that can predict a building’s response to disturbances and detect anomalies and damage. Co-PIs on the project are Professor Eduardo Kausel of CEE, Professor Edward Adelson and senior research scientist John Fisher of CSAIL, and Professor Fredo Durand of EECS and CSAIL. Draper Laboratory participates as a subcontractor. Read more about Green Building monitoring.

A study by first-year M.S.T. student Mike Wittman and aeronautics/astronatics researcher Bill Swelbar was cited in a Wall Street Journal article and on National Public Radio May 8. The study shows that the health of the airline industry has improved since 2007 in part because large airlines are consolidating flights to larger airports and eliminating flights to midsize and small airports. The overall effect has been to help the industry, but decrease options and increase fares somewhat for air passengers flying to or from smaller airports. Read more about Wittman's research.

Studies of human mobility usually focus on either the small scale — individuals’ daily commutes — or the very large scale, such as using air-travel patterns to track the spread of epidemics over time. The large-scale studies, now made possible by vast data generated and collected by technologies like sensors and cellphones, are very good at describing the big picture, but don’t provide detail at the individual level. Smaller-scale studies have the opposite characteristic: their findings generally can’t be scaled up from the individual to populations. But a new study by CEE Professor Marta González and postdoctoral associate Christian Schneider bridges that gap. It uses big data and the methodologies of statistical physics and network theory to describe the daily travel behavior of individuals, behavior that holds true at the larger scale of the entire population of two cities on different continents.

Eric Adams, senior lecturer, senior research engineer and director of the CEE M.Eng.program, is the subject of a news story on the MIT Industrial Liaison Program (ILP) website. The article describes how Adams’ research in environmental fluid mechanics has helped engineers better understand oil spills. Specifically, his studies of multi-phase pollutants — fluid set in motion by the buoyancy of bubbles, droplets and particles — have provided important insights into what happens during a deep ocean oil spill. He has shown that most oil from an oil spill will mix with water instead of rising directly to the surface, disproving the adage that oil and water don’t mix. Adams is also working on ways to reduce the amount of atmospheric carbon dioxide by releasing carbon dioxide hydrates directly into the ocean.

Collaborative work by Professor Markus Buehler and postdoctoral associate Seunghwa Ryu and researchers at Duke University demonstrates the use of mechanical instabilities in graphene to reversibly control its surface properties. The researchers showed that substances like water droplets have a distinct way of interacting with graphene's surface by applying mechanical strain to the system, which in turn changes the nanoscale structure of the graphene film. Harnessing a nanoscale crumpling (or buckling) instability in graphene allowed the researchers to make the graphene's surface at the macroscale highly water repellent, creating a reversible “Lotus effect” that causes a water droplet to form a spherical shape and roll along the surface. Buehler and Ryu, now an assistant professor at Korea Advanced Institute of Science and Technology, worked on simulations and theory and the Duke researchers ran the lab experiments. Applications for this type of mechanical instability in graphene include superhydrophobic and on-demand self-cleaning surfaces, as well as electrodes that make use of graphene's electronic properties. The work was published online Jan. 20 in Nature Materials.

Scientists track ocean microbe populations in their natural habitat to create a ‘day in the life’ montage
January 22, 2013
Microbiologists who study wild marine microbes face enormous challenges in getting a clear picture of the daily activities of their subjects. But a team of scientists led by Professor Edward DeLong recently figured out how to make the equivalent of a nature film, showing the simultaneous activities of many coexisting species in their native habitat over time. Instead of making a movie, the scientists used a robotic device that drifted in the water gathering samples of one billion microbes every four hours. Similar to fast photography that stops action, the robotic device “fixed” each sample so that whatever genes the microbes were expressing at the moment of capture were preserved for later study in the lab, where the scientists created a time-lapse montage of the daily labors of microbes.

Zara L'Heureux, a senior in 1C, presented a poster at the American Association of Aerosol Research's (AAAR) annual meeting in October 2012 based on fieldwork research performed by civil and environmental engineering undergraduates in CEE's Traveling Research Environmental Experiences (TREX) January 2012 program. The poster, "Online, Mobile Measurements of the Chemical Composition of Volcanic Smog (Vog)," described the study, which aimed to characterize the evolving composition of vog from Kilauea, an active volcano on the island of Hawaii. The TREX 2012 team of 14 undergraduates used an SUV carrying a suite of real-time aerosol and gas phase monitors to intercept and sample vog at multiple locations downwind of the volcano. These are the first known real-time measurements of the composition of volcanic aerosol.
Vog has become a severe environmental problem on Hawaii since a new vent opened in Kilauea in 2008. Sulfur dioxide gas and particulate sulfate in the plume are blown south-southwest by tradewinds, greatly impacting the southern portion of the island, particularly the town of Pahola. On some days, the plume is then picked up by offshore winds and blown northward along the western shore, impacting Hilo, the largest city on the island. Students will continue the work this month during TREX 2013. Co-authors of the poster are Eben Cross, L'Heureux, Lisa Wallace, Anna Kelly, Kelly Daumit, Philip Croteau, John Jayne, Douglas Worsnop and Professor Jesse Kroll. Read more in the TREX 2012 blog.

Traffic congestion can be alleviated throughout a metropolitan area by altering the trips of drivers in specific neighborhoods
December 20, 2012
In most cities, traffic growth has outpaced road capacity, leading to increased congestion, particularly during the morning and evening commutes. One way to prevent traffic tie-ups is to have fewer cars on the road by encouraging alternatives such as public transportation, carpooling, flex time and working from home. But a new study — by Professor Marta González and researchers at Central South University in China, the University of California at Berkeley and the Austrian Institute of Technology — incorporates data from drivers’ cellphones to show that the adoption of these alternatives by a small percentage of people across a metropolitan area might not be very effective. However, if the same number of people, but from a carefully selected segment of the driving population, chooses not to drive at rush hour, this could reduce congestion significantly.

Research shows why slight increase in flexibility of manufacturing plants optimizes efficiency and cost
December 17, 2012
Professor David Simchi-Levi and doctoral student Yehua Wei applied a combination of optimization and stochastic methodologies to explain the effectiveness of “long chain” flexibility design in manufacturing operations. With the long chain design, manufacturing plants are endowed with the capacity to produce exactly two different products and every product is produced by exactly two plants. The design can be applied to other systems, including the cross-training of workers on an assembly line, supply chains, queuing networks, and people and tasks in a call center. But until now, nobody had explained or proved mathematically why the long chain works better than other flexibility models. Read the December issue of On Balance.

The Oceans at MIT website ran an article by Genevieve Wanucha about the research of CEE Professor Roman Stocker's environmental microfluidics lab, which uses small devices to create mini-habitats for ocean microbes. “It’s the same as studying any other complex ecosystem, for example a jungle,” says Stocker. “Ultimately, if you want to understand the ecosystem on the large scale, you have to go down to the level of the single organism: how it finds food, how it competes, how it is affected by its environment. The challenge in our case is that the single organism is invisibly small.” Read the story.

Senior lecturer Susan Murcott gave a keynote speech at the World Science for Peace Conference in Milan last month. Sponsored by the Veronesi Foundation, the conference brought together government leaders, Nobel Prize winners, academics, progressive social activists, media and youth to discuss issues falling under the theme, Towards a More Equal World. Murcott addressed problems of water scarcity and water access in the developing world, particularly as they relate to women, who generally bear the burden of providing water for their families. Murcott presented Pure Home Water (PHW), a social enterprise she co-founded in 2005 in Tamale, Ghana, as one example of a viable solution to these problems. PHW makes it possible for women potters and factory workers to manufacture ceramic pot filters in their own communities that can be used by households to purify water. Since its founding, PHW has involved more than 100 MIT students in research and service projects addressing water quality, sanitation, hygiene and health. Watch a video.

In late September, Professor Jerome Connor’s latest book was published, this one written with co-author Susan Faraji of University of Massachusetts Lowell. Fundamentals of Structural Engineering (Springer, 2013) is the sixth book Connor has authored or co-authored, but it is his first textbook for undergraduates. The 1,120-page book can be used for teaching three subjects: Structural Analysis I and II and Practice of Structural Engineering. Connor says his goal is to modify the teaching paradigm to incorporate computer-based computation and analysis into undergraduate curricula. “Engineers reason about behavior using simple models and intuition they’ve acquired through problem-solving experience,” says Connor. “The approach in this book will help students develop this type of intuition through computer simulation, which allows one to rapidly explore how the structure responds to changes in geometry and physical parameters.” Read the E-book online from within MIT or from outside MIT.

Oceanographers have long assumed that because turbulence distributes nutrients uniformly in ocean water, and because the ability of tiny organisms to move around is insignificant compared to this turbulence, there was no reason for ocean bacteria to move at all. Sea-dwelling bacterial life, they believed, should consist just of static feeders. That view has now been upended by research conducted by Professor Roman Stocker and John R. Taylor, a former postdoctoral associate. It turns out that swimmers and passive feeders each have some advantages — but also pay some costs — in food gathering. The results, based on a computer model that for the first time considers nutrient competition by bacteria in a turbulent flow, were published in the Nov. 2 issue of Science, along with a review article by Stocker about ocean microbes interactions with their environment.

Researchers in MIT’s Concrete Sustainability Hub are making steady progress toward learning exactly how the cement paste that works as glue in concrete hardens during the first hours after water and cement powder are mixed. First they determined that cement paste can be described as a granular aggregate, where the particles or basic nanoscale units pack together most densely when arranged orderly. A few years later they discovered that the calcium-silicate-hydrate (C-S-H) molecules that make up the basic nanoscale unit of cement have a disorderly geometric arrangement, rather than the orderly crystalline structure scientists had long assumed. In new work, they found that the size of C-S-H particles themselves is also somewhat disorderly. The particles form at random sizes, not in homogenous spheres, and the diversity in particle size leads to a denser, disorderly packing of the particles, which corresponds to stronger cement paste. A paper by CEE postdoctoral associate Enrico Masoero, Professor Franz-Josef Ulm, senior research scientist Roland Pellenq and co-authors appeared in the Oct. 12 issue of Physical Review Letters.

New research by Professor Markus Buehler and doctoral student Zhao Qin on the fracture mechanism of ice shows that ice cracks more easily when exposed to carbon dioxide. Using a series of atomistic-level computer simulations to analyze the dynamics of molecules, they found that carbon dioxide forms hydrogen bonds with ice at a crack boundary, then breaks those bonds as it moves toward the tip of the crack. When bonds break near the crack tip, the energy released weakens the ice and makes it more apt to fracture. The research could be used to study ice fracture in other chemical environments or even be scaled up and incorporated into models of glacier dynamics. A paper on this work appeared in the Oct. 11 issue of the Journal of Physics D: Applied Physics.

Competition is a strong driving force of evolution for organisms of all sizes; those individuals best equipped to obtain resources adapt and reproduce, while others may fall by the wayside. Many organisms also form cooperative social structures that allow resources to be defended and shared within a population. Surprisingly, even microbes have a somewhat sophisticated social structure that relies on cooperation, according to Professor Martin Polz and postdoctoral associate Otto Cordero. These researchers recently found evidence that some ocean microbes wield chemical weapons — antibiotics — that are harmless to close relatives within their own population, but deadly to outsiders. Three CEE undergrads are co-authors on the paper. Read news release.

Research by Professor David Simchi-Levi was the topic of an article in the July 18 issue of the Wall Street Journal. Simchi-Levi surveyed 108 U.S. manufacturing companies, mostly with annual sales over $1 billion, and found that about 14 percent plan to "reshore" or move some of their manufacturing back to U.S. soil. Several things influenced this decision, Simchi-Levi says, including the need to move products from plant to customer more quickly, reduce transportation and warehousing costs, and create jobs back home.

Public health crises of the past decade have heightened awareness that new viruses or bacteria could spread quickly across the globe, aided by air travel. While epidemiologists and scientists who study complex network systems are working to create mathematical models that describe the worldwide spread of disease, to date these models have focused on the final stages of epidemics, examining the locations that ultimately develop the highest infection rates. But a new study by Ruben Juanes, Marta González, Christos Nicolaides and Luis Cueto-Felgueroso shifts the focus to the first few days of an epidemic, determining how likely the 40 largest U.S. airports are to influence the spread of a contagious disease originating in their home cities.

A new study by Professor Franz-Josef Ulm and Ph.D. student Mehdi Akbarian shows that using stiffer pavements on the nation’s roads could reduce vehicle fuel consumption by as much as 3 percent — a savings that could add up to 273 million barrels of crude oil per year or $15.6 billion, at today’s oil prices, and a decrease in CO2 emissions. Ulm and Akbarian use mathematical modeling to look at the effect of pavement deflection on fuel consumption across the entire U.S. road network, and conclude that because of the way energy is dissipated, the maximum deflection of the load is behind the path of travel, making the tires on the vehicle drive continuously up a slight slope.

Professor Sallie W. (Penny) Chisholm of CEE and biology and Professor John Cullen of Dalhousie University will receive the American Society for Limnology and Oceanography's Ruth Patrick Award — which honors research in basic aquatic science that helps identify, analyze and/or solve environmental problems — for their "significant contributions to the global community in their foresight and effective efforts in addressing the environmental impacts of ocean iron fertilization," the citation said. Shortly after the idea surfaced in 1988 of using iron fertilization to prompt the growth of phytoplankton which might serve as a CO2 sink, Chisholm and Cullen co-chaired an international symposium to foster discussion on this topic among scientists. The conference ended with a resolution that, because of the potential damage that could result from such a large-scale experiment, iron fertilization should not be viewed as a method for solving the CO2 emissions problem. Chisholm and Cullen went on to write several influential articles on the science and policy dimensions of ocean fertilization.

In two papers appearing in March issues of the Proceedings of the National Academy of Sciences, Professor Roman Stocker and co-authors explore how the environment influences the movements of marine plankton. In “Low-Reynolds-Number Swimming at Pycnoclines” (layers of ocean water where density increases sharply with depth), the researchers describe how buoyancy increases the energy expenditure of motile microbes and stifles their nutrient uptake, but also increases their stealth, making their movements more difficult for predators to detect. In “Bacterial Rheotaxis,” the scientists discovered that a subtle interplay between a flow velocity gradient and the helical shape of a bacterium’s flagella generates a torque that alters the bacterium’s swimming direction, driving it off course in a microscale version of a baseball pitcher’s curveball.

Bacteria adapt to habitats through random genetic mutations and gene exchange. But how does an advantageous mutation spread from a bacterium to a population? Does the gene sweep through a population or does an individual bacterium obtain the gene, then replicate its genome many times to form a new and better-adapted population? Researchers including CEE Professors Eric Alm and Martin Polz and MIT alumnus Jesse Shapiro ’10 show that genes can sweep through populations on their own, indicating that the process of evolution in bacteria is very similar to that of sexual eukaryotes.

For more than half a century, people interested in modeling the movement of people and goods between cities, states or countries have relied on a statistical formula called the gravity law, which measures the “attraction” between two places. Though widely used, the gravity model isn’t very accurate in making predictions. Now CEE Professor Marta González and researchers from Northeastern University and the University of Padua have identified an underlying flaw in the gravity model: The distance between two cities is far less important than the population size in the area surrounding them. The team created a new model that takes human motives into account and in five types of mobility studies the new model’s predictions were far more accurate than the gravity model’s.

The silk that spiders use to build their webs, trap their prey and dangle from your ceiling is one of the strongest materials known. But it turns out it’s not simply the material’s exceptional strength that makes spider webs so resilient; it’s the material’s unusual combination of strength and stretchiness — silk’s characteristic way of first softening and then stiffening when pulled. These properties, scientists have found, vary depending on the forces applied, as well as on the overall design of the web. Professor Markus Buehler, graduate students Steven Cranford and Anna Tarakanova, and Nicola Pugno of the Politecnico di Torino in Italy find evidence of the key properties that make webs so resilient and relate those properties back to the molecular structure of silk fibers.

CEE researchers Professor Sallie (Penny) Chisholm and postdoctoral associate Qinglu Zeng have discovered that certain photosynthetic ocean bacteria need to beware of viruses bearing gifts. These viruses are really con artists carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship. The con occurs when a grifter virus injects its DNA into a bacterium living in a phosphorus-starved region of the ocean. Read a news release.

CEE postdoc finds that pulling CO2 from the air would not be cost-effective in the foreseeable future
January 3, 2012
Since most of the world’s governments have not yet enacted regulations to curb emissions of greenhouse gases, some experts have advocated the development of technologies to remove carbon dioxide directly from the air. But a new MIT study co-authored by CEE postdoc Kurt Zenz House (who works in Professor Charles Harvey's lab) shows that, at least for the foreseeable future, such proposals are not realistic because their costs would vastly exceed those of blocking emissions right at the source, such as at the powerplants that burn fossil fuels.

All biological sensory systems, including the five human senses, have something in common: when exposed to a sustained change in sensory input, the sense eventually acclimates and notices subsequent changes without comparing them with the initial condition. This autonomous tuning of perceptions, known as sensory adaptation, has been recognized for more than a century. A new study by Professor Roman Stocker, Tanvir Ahmed Ph.D. ’11 and co-authors demonstrates that even microbes have sensory adaptation so precise that their behavior remains identical in ever-changing background conditions.

Professor Jerome Connor and Simon Laflamme Ph.D. '11, working with physicists at the University of Potsdam in Germany, recently proposed a new method for the electronic, continual monitoring of structures. In papers appearing in Structural Control Health Monitoring (December 2010) and the Journal of Materials Chemistry (April 2011) the researchers describe how a flexible skin-like fabric with electrical properties could be adhered to areas of structures where cracks are likely to appear, such as the underside of a bridge, and detect cracks when they occur. Installing this “sensing skin” would be as simple as gluing it to the surface of a structure in the length and width required. Read a news release.

It might not seem like scraping the top of a cold stick of butter with a knife could be a scientific test, but Professors Franz Ulm and Pedro Reis and graduate student Ange-Therese Akono say the process is very similar to the “scratch test,” which is perhaps the oldest known way to assess a material’s hardness and strength. Using butter as a launching point, they found that the scratch test is actually measuring a material’s toughness rather than its strength. Read a news release.

In an analysis published in Physical Review Letters, researchers led by Professor Ruben Juanes show that the injection of a thin or low-viscosity fluid into a much more viscous fluid (think of water spurting into molasses) will cause the two fluids to mix very quickly via a physical process known as viscous fingering. The thinner liquid will form fingers as it enters the thicker liquid, and those fingers will form other fingers, and so on until the two liquids have mixed uniformly. For maximum mixing to occur quickly, the ideal ratio of the viscosity of any two fluids depends on the speed at which the thinner liquid is injected into the thicker one. Read a news story.

During Campus Preview Weekend, Professor Franz Ulm participated in a Professor Talent Show hosted by SaveTFP, a student group that facilitates all-inclusive student social activities. Ulm's talk focused on the mechanics of scraping the top of a cold stick of butter. After defining the problem mathematically, he stated that it takes a bit less force (he's always really tired in the morning, he says) to scrape a narrow, deep strip of butter than a wider, shallow one. He went on to show how the mechanics of this problem relate to the nation's energy reserves and ended by warning the students that if they want to get famous, they should not become engineers. "Engineers only get famous when things go wrong," he said to laughter. View the video (5:50 to 19:15).

Professor Roman Stocker wrote an invited news commentary that accompanied an article in the Feb. 2 Early Edition of the Proceedings of the National Academy of Sciences about a newly discovered mechanism of locomotion used by marine microbes. In his commentary, "Reverse and flick: Hybrid locomotion in bacteria," Stocker writes: "Our understanding of bacterial locomotion has long been driven and biased by the wealth of knowledge on E.coli," which has four to eight flagella, each "powered by a reversible rotary motor. When all motors spin counterclockwise, hydrodynamic interactions cause the flagella to form a bundle that propels E. coli forward in a nearly straight 'run.' When one or more motors switch direction, the bundle comes apart, causing a change in direction." But many marine microbes have only a single flagellum, so how do they change direction? Xie et. al. describe a means for these cells to change direction by reversing, then using a flick of the flagellum to propel in a different direction.

Course 1 senior Kallie Hedberg and junior Julia Hopkins are co-authors of a paper that appeared in a March issue of the American Journal of Disaster Medicine. "Vaccine Availability in the United States during the 2009 H1N1 Outbreak" was written by Hedberg, Hopkins, Professor Richard Larson of the Engineering Systems Divison (ESD) and co-authors. Larson said the 1C students "worked tirelessly" with the Centers for Disease Control-supported ESD Flu Team, performed the majority of the research that led to the paper, and did much of the writing. The paper "details statistically the supply-chain mishaps in production and delivery of the H1N1 flu vaccine … is already leading to two follow-on papers … and an improved set of policies for vaccine distribution. We believe the paper demonstrates how an MIT engineering approach can add value in areas not traditional to engineering," said Larson.

Senior Research Associate (retired) Carl Martland, has a new book out titled, "Toward More Sustainable Infrastructure: Project Evaluation for Planners and Engineers" (Wiley 2011). Based on a subject he developed and taught at MIT (1.011 Project Evaluation), the book prepares readers to "evaluate projects based on an appreciation of the needs of society, the potential for sustainable development and recognition of the problems that may result from poorly conceived or poorly implemented projects and programs." Martland, a railroad transportation specialist, was quoted in an article appearing in the Boston Globe Feb. 14 about the new CSX railyard in Worcester, which uses cranes to lift and move cargo containers between railcars and trucks, rather than the older, less efficient forklift-like sideloaders.

Efforts to prevent or reverse eutrophication in freshwater typically aim to decrease the amount of phosphate entering the lake or river in runoff from the watershed. But a new study by Professor Harry Hemond and Katherine Lin ’05 (who performed the research as a UROP student) suggests that phosphate control measures that simultaneously decrease nitrate inflow could, paradoxically, result in an increased release of phosphate from lake sediments that have become enriched after years of heavy phosphate inflow. Incorporating this information into engineering models of lake eutrophication could make them more accurate and useful. Read a news story.

In an opinion piece in Technology Review, Professor Eduardo Kausel writes about the engineering and planning aspects of rebuilding that will be required in the wake of the earthquake and tsunami that hit Japan March 11. "Given the huge and tragic loss of life that has resulted, no compassionate human being could possibly wish last week’s devastating earthquake and subsequent tsunami on any country. But if it had to happen – and it is an inescapable geological fact that earthquakes do have to happen – there are many worse places it could have happened. In a very real sense, Japan was prepared for it and, unlike so many parts of the world hit by devastating earthquakes, it is well-placed to embark on the massive rebuilding exercise that will now ensue."

Committee says DOD should pay some of the costs of transportation infrastructure near U.S. military bases
March 7, 2011
CEE Professor Joseph Sussman recently chaired a congressionally mandated committee that released a report calling for the Pentagon to pay some of the cost of new transportation infrastructure needed to mitigate the relocation of tens of thousands of military personnel later this year, rather than making local and state governments shoulder the entire burden. The Feb. 7 report also states that some of this funding should go towards the creation or enhancement of public transportation and not focus solely on roads and highways, as has been done in the past.

An article in the Feb. 26 Boston Globe focuses on Professor John Ochsendorf and his new book,"Guastavino Vaulting: The Art of Structural Tile" (Princeton Architectural Press, 2010). Architect Rafael Guastavino (1842–1908) and son are famous for their technique of constructing architectural arches and ceilings using thin interlocking tiles. These vaults were used in hundreds of large public projects across the U.S., including the Boston Public Library and New York City's Grand Central Terminal, but the Guastavino name isn't well known by the general public, mainly because the family served as contractor rather than primary architect on these projects. Ochsendorf's book traces the development of the vaulting technique from its origins in Europe though its use in the United States, and includes photographs by Michael Freeman. Ochsendorf is a professor of civil and environmental engineering and architecture. He received a MacArthur Fellowship in 2008.

Adding particles to liquids to make currents visible is a common practice in the study of fluid mechanics, one that was adopted and perfected by artist Paul Matisse in sculptures he calls Kalliroscopes. Matisse’s glass-enclosed liquid sculptures contain an object whose movement through the liquid creates whorls that can be seen only because elongated particles trailing the object align with the direction of the current; light reflects off the particles, making the current visible to the viewer. Professor Roman Stocker and his research team recently demonstrated that this same phenomenon is responsible for the swirling patterns scientists typically see when they agitate a flask containing microbes in water; many microbes are themselves elongated particles that make the whorls visible. More importantly, they say this phenomenon occurs in the ocean when elongated microbes caught in a current align horizontally with the ocean surface, affecting how much light goes into the ocean and how much bounces off as backscatter.

Professor Eric Alm and recent graduate Lawrence David have created a sort of genomic fossil that shows that the collective genome of all life underwent an enormous expansion about 3 billion years ago, which they're calling the Archean Expansion. Many of the new genes appearing in the Archean Expansion are oxygen related, and could be the first biological evidence of the Great Oxidation Event, the period in Earth's history when oxygen became so plentiful that many anaerobic life forms may have become extinct. A report of this work appeared in Nature online Dec. 19. Read a news release.

Professor Joseph Sussman told ITS International that the U.S. transportation industry needs to come up with a new vision for multimodal transportation that will include Intelligent Transportation Systems and "capture the imagination" of the public, which would then be more willing to provide funding. "Current activities are fragmented, and the public is very sceptical of a political system that builds 'bridges to nowhere' rather than focusing on real issues and problems in a visionary way." He also calls for a new type of transportation professional who thinks broadly about transportation technologies and how they relate to transportation systems and institutions. Sussman is chair of the ITS Program Advisory Committee for the U.S. Department of Transportation. To read the full interview, go to the ITS International website.

The settling of particulate organic matter in the ocean is the main means of moving carbon from surface waters toward the deep sea. As the particles fall, microbes colonize them and degrade some of the organic carbon, releasing it into the water. Because the particles are composed of 95 percent or more seawater trapped in a porous, gel-like matrix, and the ocean is stratifed by water of different densities, the particles often reach a depth where they approach neutral buoyancy, leaving them stranded in thin layers affecting how much carbon microbes degrade. Professor Roman Stocker and colleagues demonstrated that the retention time in the layers is due to the diffusive exchange of low-density water from the hollows of the particles with heavier ambient water. Using lab experiments based on time-lapse microphotography, they showed that larger aggregates spend more time in thin layers than smaller particles, with a retention time that increases quadratically with particle radius.

A book written by Doherty Associate Professor Charles Harvey and recent alumnus Khandaker Ashfaque about their research tracing the source of arsenic in Bangladeshi wells was published in the summer. “Arsenic Mobilization in Groundwater: A Case Study in Bangladesh” (VDM Verlag, June 2009) describes the co-authors’ findings on research carried out for six years beginning in 2001. The authors write: “Naturally occurring arsenic in groundwater has emerged as a global problem. Millions of people throughout the world are affected by arsenic poisoning in drinking water. However, very little work has been conducted to understand hydrogeochemical dynamics and the transport of arsenic. We use a small region in Bangladesh where high levels of arsenic have been found as the study area. We carried out various field experiments, laboratory analyses and numerical modeling to investigate the geochemical and hydrological impacts on arsenic mobilization in groundwater.” Ashfaque, who received his Ph.D. in 2007, is now a remediation engineer with ARCADIS Inc. working out of the Newtown, Penn. office.

In the 2,000 or so years since the Roman Empire employed a naturally occurring form of cement to build a vast system of concrete aqueducts and other large edifices, researchers have analyzed the molecular structure of natural materials and created entirely new building materials such as steel, which has a well-documented crystalline structure at the atomic scale. Oddly enough, the three-dimensional crystalline structure of cement hydrate — the paste that forms and quickly hardens when cement powder is mixed with water — has eluded scientific attempts at decoding, despite the fact that concrete is the most prevalent man-made material on earth and the focus of a multibillion-dollar industry that is under pressure to clean up its act. A paper published online in the Proceedings of the National Academy of Sciences (PNAS) this week announces the decoding of the three-dimensional structure of the basic unit of cement hydrate by a group of MIT researchers who have adopted the team name of Liquid Stone.

Scientists worry that rising global temperatures accompanied by melting permafrost in arctic regions will initiate the release of underground methane into the atmosphere. An MIT paper elucidates how this underground methane in frozen regions would escape and concludes that methane trapped under the ocean may already be escaping through vents in the sea floor a million times faster than previously believed. Some scientists have associated the release, both gradual and fast, of subsurface ocean methane with climate change of the past and future. Read more.

Ph.D. candidate Simon Laflamme spent three weeks in July at the University of Illinois at Urbana-Champaign attending the Asia-Pacific Summer School (APSS) on Smart Technologies. Funded by the National Science Foundation, the APSS program gathered researchers from Japan, China, South Korea, Italy and the U.S. for lectures and labs on structural health monitoring, structural control and smart materials. Students formed eight teams of five to six people and competed on field tasks for structural health monitoring and structural control, plus oral presentations on the results. Laflamme’s team placed first with the highest combined score. “For the health monitoring task, we had to determine the modal frequencies of an existing bridge, which in our case was a two-span steel truss bridge. The second task was to design a controller to stabilize a double inverted pendulum, which was a highly nonlinear system,” said Laflamme. He also gave an invited talk, “Adaptive Neurocontrol for Civil Structures.”

Parsons Laboratory graduate students Gajan Sivandran and Sarah Jane White each received an Outstanding Student Paper Award (hydrology section) for work presented at the American Geological Society's 2008 Fall meeting in San Francisco. Sivandran, a member of the Rafael Bras group, was recognized for "An Eleven-Year Validation of a Physically-Based Distributed Dynamic Ecohydrological Model tRIBS+VEGGIE: Walnut Gulch Experimental Watershed, Arizona." White's paper, "The Rise of III-V Semiconductors and their Impact on Environmental Indium Concentrations," considered the environmental cycling of trace metals. “I study the potential impacts of metals, including indium, that are found in new semiconductor technologies such as photovoltaic panels and high-efficiency LEDs,” she explained. “The use of indium is increasing rapidly, but its environmental behavior and impacts are poorly understood. The ultimate goal is to determine the environmental impacts of industrially-important metals early on, so that new technologies can be developed sustainably.” White works with Professor Harold Hemond.

The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease, stem from a genetic mutation that causes the incorrect substitution of a single amino acid in the chain of thousands of amino acids making up a collagen molecule, the basic building block of bone and tendon. According to Professor Markus Buehler of MIT, that minuscule encoding error creates a defective collagen molecule that, at the site of the amino acid substitution, repels rather than attracts the collagen molecule alongside it. This creates a tiny rift in the tissue, which when repeated in many molecules, leads to brittle tissue, broken bones, deformity and, in the most severe form of the disease, death. For example, if healthy collagen tissue looked like a sheet of paper, diseased collagen tissue would look more like a sheet of paper full of tiny perforations. At each of these perforations, the sheet would be considerably more prone to tearing. Read release.

Nanoelectromechanical systems devices have the potential to revolutionize the world of sensors: motion, chemical, temperature, etc. But taking electromechanical devices from the micro scale down to the nano requires finding a means to dissipate heat output. In a paper in Nano Letters, Professor Markus Buehler and postdoctoral associate Zhiping Xu say the solution is to build these devices using a thermal material that dissipates heat from the device’s center through a hierarchical branched network of carbon nanotubes. The template for this thermal material’s design: a living cell. Read more.

A book based on senior lecturer and senior research associate John Germaine’s 25 years experience teaching geotechnical and other civil engineering measurement subjects has just been published by John Wiley & Sons. “Geotechnical Laboratory Measurements for Engineers,” written by Germaine and his wife, Amy Varney Germaine ’96, S.M. ’98, covers many of the basic geotechnical tests used in undergraduate and graduate courses, as well as in commercial laboratories. “I have continually developed and revised experimental modules focused on specific tests to teach methods, theory, equipment, procedures and interpretation. This book is a greatly expanded edition of these modules,” said Germaine. “It also draws heavily on my research and consulting experience working with a wide variety of geotechnical materials. We included an online supplement providing blank data sheets, a full set of measurements for anyone trying to teach the class without a physical laboratory, and a set of instructor calculations. Getting quality results from a test often requires slight modifications to standard techniques, what many refer to as the ‘art’ of testing. We tried to capture some of this thinking in the book.”

CEE doctoral students Amy Mueller and Matt Orosz recently won an Environmental Protection Agency (EPA) grant for economically sustainable programs that protect the environment. Mueller and Orosz — members of the research group of Professor Harold Hemond — have been developing solar power technology to replace polluting diesel generators in remote villages of Lesotho, Africa for several years. Their solar power generator design uses a parabolic trough to concentrate the sun’s energy; it can provide three to five kilowatts of power plus hot water. The EPA award includes a $75,000 grant to help them install a next-generation prototype solar collector at a clinic this fall or early next spring. Mueller and Orosz designed the solar plant to be built using locally available parts and labor. The ultimate goal, Mueller noted, is to teach local residents how to construct the solar power plants, thus providing a business opportunity for residents, as well as strengthening the local electricity infrastructure.

Assistant Professor Markus Buehler is executive editor of a new journal launched March 2009: The International Journal of Applied Mechanics (IJAM). IJAM focuses on innovative research in mechanics including solid mechanics, fluid mechanics, thermodynamics and material science, and in emerging areas such as biomechanics, electromechanics, and the mechanical behavior of advanced materials and nanomechanics. The inaugural issue of the quarterly journal contains an article co-written by Buehler and CEE graduate students Zhao Qin and Steven Cranford, and former visiting graduate student Theodor Ackbarow. “Our paper shows that by using hierarchical nanostructures found in biology, we can achieve unusual properties in synthetic materials, such as enabling them to combine strength with robustness,” said Buehler. "Most engineered materials cannot yet combine these opposing properties. Through our work, we hope to develop self-assembled bio-inspired materials capable of fulfilling multiple competing properties, while requiring less material and less energy to be created.” A figure from the article, “Robustness-Strength Performance of Hierarchical Alpha-Helical Protein Filaments,” depicting the structural hierarchies in a helical protein decorates the issue's cover. IJAM is available through the MIT Libraries.

An ingenious new method of obtaining marine microbe samples while preserving the microbes’ natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs — snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence in a natural setting may make it possible finally to learn on a broad scale how microbial communities living at different ocean depths and regions respond to environmental stimuli. Edward DeLong, a professor of civil and environmental engineering (CEE) and biological engineering, and co-authors Yanmei Shi, a graduate student in CEE, and postdoctoral associate Gene Tyson describe this work in the May 14 issue of Nature.

Two DLab teams mentored by Senior Lecturer Susan Murcott won top prizes at the IDEAS Competition May 4. Global Citizen Water Initiative was honored for its innovations related to Murcott’s research supported by Google.org and the Tides Foundation. The student team, which includes Jenny VanCalcar M.Eng. '07, created a global water quality map and developed very-low-cost E. coli/TC water quality test kits that use body heat for incubation. Murcott and team will take that project further this summer in Ghana and the Himalayas. The other winning team, HeatSource, developed a paraffin-based, solar-heated tile that can be enclosed in local textiles and worn against the skin to provide warmth. The tile can be used as a substitute for dung or wood fires used for space heating in Himalayan homes. Dung and wood for those fires are gathered by women and girls, who often cannot go to school because they are gathering fuel.

Separating the good from the bad: Two-handed microbes point to new method for isolating harmful forms of chemicals
April 15, 2009
Professor Roman Stocker, graduate student Marcos, and colleagues at Brown University studying how marine bacteria move recently discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions. This finding and the possibility of quickly and cheaply implementing the segregation of two-handed objects in the laboratory could have a big impact on industries like the pharmaceutical industry, for which the separation of right-handed from left-handed molecules can be crucial to a drug’s safety.

Using green and blue and yellow, too, an MIT scientist and a Caldecott Award-winning author/illustrator have teamed up to produce a lavishly illustrated children’s book that explains how the sun kindles life on Earth through photosynthesis. Most people crave sunlight, especially during the cold winter months, but too few understand that the sun does much more than keep us warm. After reading “Living Sunlight: How Plants Bring the Earth to Life” (Scholastic 2009), the next generation may grow up with a better understanding of how the sun’s energy sparks green plants’ ability to photosynthesize, which makes it possible for humans to exist on planet Earth.

Not far beneath the ocean’s surface, tiny phytoplankton swimming upward in a daily commute toward morning light sometimes encounter the watery equivalent of Rod Serling’s Twilight Zone: a sharp variation in marine currents that traps billions of these single-celled organisms and sends them tumbling head over heels until a shift in wind or tide alters the currents and sets them free. Scientists are aware of these thin layers of single-celled creatures and their enormous ecological ramifications, but until now, they knew little about the mechanisms responsible for their formation. The explanation by researchers in MIT’s Department of Civil and Environmental Engineering of how these common, startlingly dense layers of photosynthetic phytoplankton form, moves the scientific community a step closer to being able to predict harmful algal blooms, a well-known example of which is red tide. The work also opens new perspectives on other phenomena, like predatory feeding by larger organisms at these ecological hotspots. Read more.

MIT researchers who study the structure of protein-based materials with the aim of learning the key to their lightweight and robust strength have discovered that the particular arrangement of proteins that produces the sturdiest product is not the arrangement with the most built-in redundancy or the most complicated pattern. Instead, the optimal arrangement of proteins in the rope-like structures they studied is a repeated pattern of two stacks of four bundled alpha-helical proteins. In a paper published in the Jan. 27 online issue of Nanotechnology, Markus Buehler and Theodor Ackbarow describe a model of the protein’s performance, based on molecular dynamics simulations.

Picture this: an accurate map of a large underground oil reservoir that can guide engineers’ efforts to coax the oil from the vast rocky subsurface into wells where it can be pumped out for storage or transport. Researchers in MIT’s Department of Civil and Environmental Engineering have developed technology that can generate such a map, which has the potential to significantly increase the amount of oil extracted from reservoirs. The new technology uses the digital image compression technique of JPEG to create realistic-looking, comprehensive maps of underground oil reservoirs using measurements from scattered oil wells. These maps would be the first to provide enough detail about an oil reservoir to guide oil recovery in the field in real time. Read more.

"It has long been known that malaria can be fought by draining swamps and paving streets," Donald McNeil Jr. writes in the Dec. 22 issue of the New York Times. "But a new study by scientists at the Massachusetts Institute of Technology suggests that simpler remedies by villagers too poor to afford bulldozers or cement can also have an impact." Professor Elfatih Eltahir led this research project, which includes work by graduate students Rebecca Gianotti and Arne Bomblies, who defended his dissertation earlier this month.

MIT researchers are working with Portuguese colleagues to design a pilot-scale device that will capture significantly more of the energy in ocean waves than existing systems, and use it to power an electricity-generating turbine. Wave energy is a large, widespread renewable resource that is environmentally benign and readily scalable. In some locations — the northwestern coasts of the United States, the western coast of Scotland, and the southern tips of South America, Africa and Australia, for example — a wave-absorbing device could theoretically generate 100 to 200 megawatts of electricity per kilometer of coastline. But designing a wave-capture system that can deal with the harsh, corrosive seawater environment, handle hourly, daily and seasonal variations in wave intensity, and continue to operate safely in stormy weather is difficult. To help engineers design such devices, Chiang Mei, the Ford Professor of Engineering in the Department of Civil and Environmental Engineering, and his colleagues developed numerical simulations that can predict wave forces on a given device and the motion of the device that will result.

It’s no simple matter to figure out how regional changes in precipitation, expected to result from global climate change, may affect water supplies. Now, a new analysis led by MIT researchers has found that the changes in groundwater may actually be much greater than the precipitation changes themselves. Conversely, the analysis showed in some cases just a 20 percent decrease in rainfall could lead to a 70 percent decrease in the recharging of local aquifers — a potentially devastating blow in semi-arid and arid regions. The research was conducted by Gene-Hua Crystal Ng, a postdoctoral researcher in MIT’s Department of Civil and Environmental Engineering (CEE), along with King Bhumipol Professor Dennis McLaughlin and Bacardi Stockholm Water Foundations Professor Dara Entekhabi, both of CEE, and Bridget Scanlon, a senior researcher at the University of Texas. The results were presented Wednesday, Dec. 17, at the American Geophysical Union’s fall meeting in San Francisco. Read more.

CEE researchers Professor Roman Stocker and post-doctoral fellow Justin Seymour have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain. The work, reported in the January print issue of American Naturalist, may lead to better predictions of marine microbes’ global-scale influence on climate. Through photosynthesis and uptake of carbon compounds, diverse planktonic marine microorganisms — too small to be seen with the naked eye — help regulate carbon flux in the oceans. Carbon flux refers to the rate at which energy and carbon are transferred from lower to higher levels of the marine food web, and it may have implications for commercial fisheries and other ocean-dependent industries. The MIT study is one of the first detailed explorations of how sea creatures so small — 500,000 can fit on the head of a pin — find food in an ocean-size environment. Read more.

Researchers at MIT recently found an elegant solution to a sticky scientific problem in basic fluid mechanics: why water doesn’t soak into soil at an even rate, but instead forms what look like fingers of fluid flowing downward. Scientists call these rivulets “gravity fingers,” and the explanation for their formation has to do with the surface tension where the water—or any liquid—meets the soil (or other medium). Knowing how to account for this phenomenon mathematically will have wide-ranging impact on science problems and engineering applications, including the recovery of oil from reservoirs and the sequestration of carbon underground. The solution reported in the Dec. 12 issue of Physical Review Letters by co-authors Luis Cueto-Felgueroso and Ruben Juanes involves borrowing a mathematical phrase, if you will, from the mathematical description of a similar problem, a solution both simple and elegant that had escaped the notice of many researchers in earlier attempts to describe the phenomenon.

To prevent global warming, researchers and policymakers are exploring a variety of options to significantly cut the amount of carbon dioxide that reaches the atmosphere. One possible approach involves capturing greenhouse gases such as carbon dioxide at the source -- an electric power plant, for example -- and then injecting them underground. While theoretically promising, the technique has never been tested in a full-scale industrial operation. But now MIT engineers have come up with a new software tool to determine how much CO2 can be sequestered safely in geological formations. Ruben Juanes, assistant professor of civil and environmental engineering, and co-author CEE graduate student Michael L. Szulczewski reported this work Nov. 18 at the 9th International Conference on Greenhouse Gas Control Technologies (GHGT-9), held Nov. 16-20 in Washington, D.C. Read more.

Anthony Guma, who graduated in June with a master's degree in Real Estate Development, won the MIT Center for Real Estate Alumni Association's best thesis award in September. Professor Richard de Neufville of CEE was Guma’s research and thesis advisor. De Neufville teaches that planners should build flexibility into design, because the function of a building, transit system, airport, etc. may vary substantially over time. In his research project, Guma analyzed how flexibility can allow a developer to take advantage of changes in the real estate market. His thesis, "A Real Options Analysis of a Vertically Expandable Real Estate Development," deals with a 30-story office building in downtown Chicago to which an additional 24 stories are currently being added.

CEE Professor Markus J. Buehler’s new book, titled “Atomistic Modeling of Materials Failure” (Springer 2008), was published in July. Intended as a reference for engineers, materials scientists and researchers in academia and industry, the book provides an introduction and an overview into the field of atomistic-based computational solid mechanics. Atomistic studies have helped Buehler and others develop new theories and insight into how cracks occur in brittle materials and how nanomaterials deform. “The main question we are concerned with is how materials fail under extreme conditions, and how the microscopic or macroscopic failure processes are related to atomistic details,” Buehler wrote in the book’s introduction. He describes how researchers can use new nanotechnology methods to create structures at the scale of single atoms to study a material’s failure.

Many lives and dollars could be saved if emergency managers could make better decisions when faced with an approaching hurricane. Now, MIT student Michael Metzger, who works with Professor Richard Larson of CEE and the Engineering Systems Division, has developed a computer model that could help do just that. Metzger's software could help emergency managers decide early on whether and when to order evacuations, and to do so more efficiently by evacuating people in stages according to population category. The tool could also help planners optimize the location of relief supplies before a hurricane hits. By analyzing data from 50 years of hurricanes and detailed information on several major ones, and by comparing the information available as a hurricane approached with data from the actual storm's passage, Metzger produced software that provides a scientifically consistent framework for planning. Metzger, who is a research assistant in the Engineering Systems Division and a Ph.D. student in the Operations Research Center, received a second-place award from the U.S. Department of Homeland Security for this work.

Emmanuel Carrier, who earned the Ph.D. in transportation earlier this year, won the Anna Valicek Medal from the Airline Group of the International Federation of Operations Research Societies in September for his paper describing his modeling of the behavior of airline passengers. The paper is based on Carrier’s doctoral research, which models how different categories of airline passengers choose itineraries and fares. For example, for some business travelers, schedule is the most important factor in decision-making; for other business travelers and most leisure travelers, ticket price is more important. Ultimately airlines can use this model to help make decisions for pricing and revenue management. Moshe Ben-Akiva, the Edmund K. Turner Professor of Civil and Environmental Engineering, and Peter Belobaba, principal research scientist in the Department of Aeronautics and Astronautics, supervised Carrier’s thesis research. Carrier now works in Kirkland, Wash., at AI Systems, a company that develops software for airlines. Read more.

We know that ocean microbes act like tiny biosensors, responding quickly to changes in the environment in ways that help us clean up chemical spills or treat raw sewage. But we know little about how they do it, including the genes and metabolic pathways involved. Metagenomics—the study of genetic material of microbial communities collected from natural environments—is a burgeoning field of genetic research particularly useful for the study of ocean microbes, because they’re difficult to culture in a lab. By focusing on the microbe’s RNA transcript profile, Professor Ed DeLong of MIT’s Department of Civil and Environmental Engineering, one of the pioneers of metagenomics, now brings us a step closer to identifying which genes are active under certain conditions.

Fred Salvucci, senior lecturer in the Department of Civil and Environmental Engineering and former Secretary of Transportation for the Commonwealth of Massachusetts, wrote an opinion piece published in the Boston Globe April 30 concerning the need to support the governor’s proposal to repair the state’s deteriorating bridges. “For too long, phrases like ‘no new taxes’ or ‘fix it first' have served as substitutes for action,” Salvucci said in the op-ed. “This sugarcoating sounded nicer than the truth: passing a growing burden to the next generation and stunting economic growth in the state. Postponement of needed transit and roadwork projects has led to a backlog of $20 billion to $30 billion in projects necessary for economic growth and public safety. The practice of deliberately underfunding infrastructure investments, in the name of ‘balancing’ budgets, has been fiscally imprudent for four reasons.” The op-ed can be read in its entirety on the Boston Globe website.
