Each year, exposure to airborne particulate matter known as PM2.5 (particles with a diameter smaller than 2.5 micrometers) leads to millions of premature deaths worldwide. Organic aerosols are the dominant constituents of PM2.5 in many locations around the world. Historically, the chemical complexity of organic aerosols has made it difficult to gauge their toxicity level. But a study led by researchers at Georgia Institute of Technology has advanced understanding of both the chemical composition of PM2.5 and the reaction of alveolar cells of the lungs exposed to this pollution, highlighting the growing threat posed to human health.
In response to changing climates, many plants and animals are moving to higher elevations, seeking cooler temperatures. But a new study from Georgia Tech and the University of Colorado Denver finds that flying insects like bees and moths may struggle with insurmountable issues to this escape route.
As part of an $11.6 million research initiative, Biological Sciences postdoctoral fellow Sarah Orr will leverage a new USDA Fellowship to study the impact of synthetic pesticides on bumblebees — a key pollinator for U.S. agricultural production.
Scientists at the Georgia Institute of Technology and Max Planck Institute for Intelligent Systems in Stuttgart have published a perspectives piece on the different tools used throughout the world aiding in the conservation of wildlife and biodiversity.
The new research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa, revealing how environmental changes have disrupted mammal communities and highlighting the urgent need for targeted conservation efforts to protect vulnerable species.
A newly funded research project might one day lead to the development of a pill or capsule able to boost the effectiveness of traditional vaccines against influenza, which kills as many as 52,000 people and leads to hundreds of thousands of hospitalizations a year in the United States.
Physicists have developed a new model and clearer picture of molecular movements within active matter — bringing science a step closer to designing specific functions into new materials, and understanding emergent behaviors.
Rare earth elements are critical to technology, electronics, and rapidly evolving clean energy efforts. Equipped with a new NSF grant, Yuanzhi Tang is helping find and unlock these key minerals in Georgia kaolin deposits.
Please join the Center for Promoting the Inclusion and Equity in the Sciences (C-PIES) in congratulating Stephanie Reikes, Greg Mayer, and Bekki George for being selected as the recipients of the 2023-2024 College of Sciences Inclusive Excellence Faculty Fellowship.
The Brook Byers Institute for Sustainable Systems (BBISS) Graduate Fellows Program provides graduate students with enhanced training in sustainability, team science, and leadership in addition to their usual programs of study.
Alex Robel and Shi Joyce Sim have a new model for how water moves under glaciers. Their theory shows that up to twice the amount of subglacial water that was originally predicted might be draining into the ocean – potentially increasing glacial melt, sea level rise, and biological disturbances.
