The result is the most precise measurement to date of the ratio of positrons to electrons in cosmic rays. Measurements of this key ratio may eventually provide…

SN Wilson belongs to a special class called Type Ia supernovae. These bright beacons are prized by astronomers because they provide a consistent level of…

In the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that…

An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first…

Patients with prostate cancer and hereditary mutations in the BRCA2 gene have a worse prognosis and lower survival rates than do the rest of the patients with…

“How these animals find their way to the right habitat is a fascinating problem,” said Brian Gaylord, professor of evolution and ecology at UC Davis and a…

Topological insulators (TIs) are an exciting new type of material that on their surface carry electric current, but within their bulk, act as insulators. Since…

An international team of researchers led by scientists from Rockefeller’s St. Giles Laboratory of Human Genetics and Infectious Diseases has now identified the…

How do nerve cells — which can each be up to three feet long in humans — keep from rupturing or falling apart?Axons, the long, cable-like projections on…

Plants exchange gases, such as carbon dioxide and oxygen, with the atmosphere via special openings in their leaves, known as stomata. A ring-shaped arrangement…

Methane is a substantial driver of global climate change, contributing 30 percent of current net climate warming. Concern over methane is mounting, due to…

Scientists at the Bonn University Hospital have now deciphered how the molecule can actually stimulate the immune system to combat viruses. The results are now…

Deposits in lakes and seas contain a wealth of information related to the environ-mental conditions prevalent during their genesis. Thus, they are an unfailing…

Researchers have newly associated nine genetic regions with a rare autoimmune disease of the liver known as primary sclerosing cholangitis (PSC). This brings…

At REHACARE 2012, Fraunhofer Institute for Manufacturing Engineering and Automation unveiled a pioneering mobile emergency assistance system that combines an…

“Our results indicate that both these phenomena, dark and bright lightning, are intrinsic processes in the discharge of lightning,” said Nikolai Østgaard, who…

In a paper to be published in an upcoming issue of Energy & Environmental Science (now available online), researchers at the U.S. Department of Energy’s…

Can lasers perform welds precisely and reliably in the midst of thundering machinery? The prototype of a new laser welder developed by an international team of…

Even bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders – in their case, viruses. Scientists at the Helmholtz…

An experimental drug has shown promise in treating influenza, preventing lung injury and death from the virus in preclinical studies, according to University…
