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.
UT Southwestern Medical Center researchers have identified a gene that protects the gut from inflammatory bowel disease (IBD).
Genetically modified organisms for pest control could end up as contaminants in agricultural products throughout the globe.
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.
Global methane and ethane emissions from oil production from 1980 to 2012 were far higher than previous estimates show, according to a new study which for the first time takes into account different production management systems and geological conditions around the world.
Methane is a potent greenhouse gas, which scientists rank as the second-most important contributor to climate change after carbon dioxide. Yet while methane concentrations in the atmosphere can be easily measured, it is difficult to determine the contribution of different sources, whether human or natural. This is necessary information for reducing emissions.
A study published in JAMA Cardiology has added to growing evidence that electronic cigarettes (e-cigarettes) are not harmless.
