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.
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).
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.
A study published in JAMA Cardiology has added to growing evidence that electronic cigarettes (e-cigarettes) are not harmless.
Genetically modified organisms for pest control could end up as contaminants in agricultural products throughout the globe.
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.
Today, more than 16 years of space-weather data is publicly available for the first time in history. The data comes from space-weather sensors developed by Los Alamos National Laboratory on board the nation’s Global Positioning System (GPS) satellites. The newly available data gives researchers a treasure trove of measurements they can use to better understand how space weather works and how best to protect critical infrastructure, such as the nation’s satellites, aircraft, communications networks, navigation systems, and electric power grid.
Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new University of Colorado Boulder-led research.
The study illustrates the significant, localized role that dark-colored particulates — which absorb more solar radiation than light-colored snow and keep more heat closer to the Earth’s surface — can play in hastening Arctic ice melt.
The study was published today in the Journal of Geophysical Research: Atmospheres, a publication of the American Geophysical Union.
In the global effort to mitigate carbon dioxide levels in the atmosphere, all options are on the table—including help from nature. Recent research suggests that healthy, intact coastal wetland ecosystems such as mangrove forests, tidal marshes and seagrass meadows are particularly good at drawing carbon dioxide from the atmosphere and storing it for hundreds to thousands of years.
