Studies advancing our understanding of fluid dynamics, environmental processes, materials science, and resilient infrastructure were some of the most popular topics this year

This year, CEE’s research efforts deepened our knowledge of public health, climate science, transportation systems, structural mechanics, and sustainable materials—contributing practical insights to challenges that matter. We’ve rounded up some of our most popular research stories to celebrate the achievements from the past year.

• High-speed videos show what happens when a droplet splashes into a pool: Findings may help predict how rain and irrigation systems launch particles and pathogens from watery surfaces, with implications for industry, agriculture, and public health.
• For plants, urban heat islands don’t mimic global warming: Scientists have found that trees in cities respond to higher temperatures differently than those in forests, potentially masking climate impacts.
• MIT engineering students crack egg dilemma, finding sideways is stronger: A new study reveals why eggshells are stronger on their sides, overturning a popular science belief.
• Eco driving measures could significantly reduce vehicle emissions: New research shows automatically controlling vehicle speeds to mitigate traffic at intersections can cut carbon emissions between 11 and 22 percent.
• Technique makes complex 3D printed parts more reliable: New research enables computer designs to incorporate the limitations of 3D printers, to better control materials’ performance in aerospace, medical, and other applications.
• Pompeii offers insights into ancient Roman building technology: MIT researchers analyzed a recently discovered ancient construction site to shed new light on a material that has endured for thousands of years.
