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.

One of the main obstacles in the production of hydrogen through water splitting is that hydrogen peroxide is also formed, which affects the efficiency stability of the reaction and the stability of the production. Dutch and Israelian researchers from Eindhoven University of Technology and the Weizmann Institute have succeeded in controlling the spin of electrons in the reaction and thereby almost fully suppress the production of hydrogen peroxide. They published these findings this week in the Journal of the American Society. The efficient production of hydrogen paves the way towards water splitting by solar energy.

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.
