Scientists capture 'redox moments' in living cells - 25/11/2013

Scientists have glimpsed key chemical events, known as redox reactions, inside living cells of fast-growing Synechococcus. The work marks the first time that redox activity, a very fast regulatory network involved in all major aspects of a cell's operation, has been observed in specific proteins...

New genomic study provides a glimpse of how whales could adapt to ocean - 25/11/2013

Researchers have completed the first in-depth minke whale genome sequence and their new findings shed light on how whales successfully adapted to ocean environment. The data yielded in this study will contribute to future studies of marine mammal diseases, conservation and evolution. Fuente :...

Scientists find brain region that helps you make up your mind - 25/11/2013

One of the smallest parts of the brain is getting a second look after new research suggests it plays a crucial role in decision making. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/E...

The physics of beer tapping - 24/11/2013

An old, hilarious if somewhat juvenile party trick involves covertly tapping the top of someone's newly opened beer bottle and standing back as the suds foam out onto the floor. Now researchers have produced new insight into the science behind the foaming, exploring the phenomenon of cavitation....

Great lakes waterfowl die-offs: Finding the source - 24/11/2013

A deadly menace stalks the loons, gulls and other water birds of the Great Lakes region: Type E botulism. Cases of the disease are on the rise, and to understand die-off origin and distribution, ocean engineers are developing a novel way of tracking waterfowl carcasses to determine the source of...

The secrets of owls' near noiseless wings - 24/11/2013

Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day...

Update: 50 percent of patients in new brain cancer study alive after five years - 24/11/2013

Eight of 16 patients participating in a study of an experimental immune system therapy directed against the most aggressive malignant brain tumors – glioblastoma multiforme – survived longer than five years after diagnosis, according to new research. Fuente :...

Meat, egg and dairy nutrient essential for brain development - 24/11/2013

"The cells of the body can do without it because they use asparagine provided through diet. Asparagine, however, is not well transported to the brain via the blood-brain barrier," said senior co-author of the study Dr. Jacques Michaud, who found that brain cells depend on the local synthesis of...

NIST demonstrates how losing information can benefit quantum computing - 24/11/2013

Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology have entangled -- linked the quantum properties of -- two ions by leaking judiciously chosen information to the environment. Fuente :...

How living cells solved a needle in a haystack problem to produce electrical signals - 24/11/2013

Scientists have figured out how cells do the improbable: pick the charged calcium ions out of vast sodium sea to generate electrical signals. The speed and accuracy of this selection is crucial to the beating of the heart and the flow of nerve impulses in the brain. The finding is likely to assist...

New genomic study provides a glimpse of how whales could adapt to ocean - 24/11/2013

In a paper published in Nature Genetics, researchers from Korea Institute of Ocean Science and Technology, Korea Genome Research Foundation, BGI, and other institutes presented the first high-depth minke whale genome and their new findings on how whales successfully adapted to ocean environment....

Scientists prove X-ray laser can solve protein structures from scratch - 24/11/2013

A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure. Fuente : http://www.eurekalert.org/pub_releases/2013-11/dna...

X-rays reveal another feature of high-temperature superconductivity - 24/11/2013

Classical and high-temperature superconductors differ hugely in their critical temperature when they lose electrical resistance. Powerful X-rays made possible to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional...

UNL scientists develop novel X-ray device - 24/11/2013

A laser-driven device developed by scientists at the Diocles Extreme Light Laboratory at the University of Nebraska-Lincoln could do for research-quality X-rays what the smart phone did for computing. Fuente : http://www.eurekalert.org/pub_releases/2013-11/uon...

Unusual greenhouse gases may have raised ancient Martian temperature - 24/11/2013

Much like the Grand Canyon, Nanedi Valles snakes across the Martian surface suggesting that liquid water once crossed the landscape, according to a team of researchers who believe that molecular hydrogen made it warm enough for water to flow.

Study identifies protein essential for immune recognition, response to viral infection - 24/11/2013

A Massachusetts General Hospital-led research team has identified an immune cell protein that is critical to setting off the body's initial response against viral infection. They found that a protein called GEF-H1 is essential to the ability of macrophages -- major contributors to the innate immune system -- to respond to...

Even if emissions stop, carbon dioxide could warm Earth for centuries - 24/11/2013

Princeton University-led research suggests that even if carbon-dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years. Thus, it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe....
