We breathe it in and out every few seconds, yet the air that surrounds us has chemical activity and variations in its composition that are remarkably complex. Teasing out the mysterious behavior of the atmosphere’s constituents, including pollutants that may be present in tiny amounts but have big impacts, has been the driving goal of Jesse Kroll’s research.

How viruses like Ebola, influenza or even the common cold adapt is a question that affects the health of everyone on earth.  A new Yale University study reveals that gradual exposure to new host species leads to major genetic changes in these pathogens — and possibly makes them more dangerous.

In Egypt, two out of five households do not have access to clean drinking water. This reality hit home for fourth-year entrepreneurship student Omar El Araby in December, when he visited the city of Asyut with Enactus Ryerson.

UT Southwestern Medical Center researchers have identified a gene that protects the gut from inflammatory bowel disease (IBD).

In a new study, Yale researchers identified a novel genetic defect that prevents brain tumor cells from repairing damaged DNA. They found that the defect is highly sensitive to an existing FDA-approved drug used to treat ovarian cancer — a discovery that challenges current practice for treatment of brain tumors and other cancers with the same genetic defect, said the scientists.
