Un libro rescata la fabulosa historia de Mónico Sánchez, un español nacido en 1880 en un pueblo miserable que emigró a Nueva York y acabó inventando un aparato portátil de rayos X y trabajando en la telefonía sin hilos ||| Fuente : http://feedproxy.google.com/~r/materia/noticias/~3...

Scientists at the University of California, Davis have engineered a strain of photosynthetic cyanobacteria to grow without the need for light. They report their findings today at the 113th General Meeting of the American Society for Microbiology. Fuente :...

Overfishing has reduced fish populations and biodiversity across much of the world's oceans. In response, fisheries are increasingly reliant on a handful of highly valuable shellfish. However, new research by the University of York shows this approach to be extremely risky. Fuente :...

Researchers at Mayo Clinic have developed a promising method to distinguish between pancreatic cancer and chronic pancreatitis -- two disorders that are difficult to tell apart. A molecular marker obtained from pancreatic "juices" can identify almost all cases of pancreatic cancer, their study...

A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing electron transfer under conditions similar to those of the early Earth. Fuente :...

Researchers at Columbia University and Stanford University have developed a computational method that enables scientists to visualize and interpret "high-dimensional" data produced by single-cell measurement technologies such as mass cytometry. The method, published today in the online edition of...

The Indo-Pacific warm pool was much dryer during the last ice age than today, because lower sea level exposed the Sunda Shelf. The large landmass, in place of the warm ocean, altered the atmospheric circulation, shifting convection further west into the Indian Ocean. These findings by scientists at...

Researchers say deaths in Manhattan linked to warming climate may rise some 20 percent by the 2020s, and, in some worst-case scenarios, 90 percent or more by the 2080s. Higher winter temperatures may partially offset heat-related deaths by cutting cold-related mortality -- but even so, annual net...

Scientists at Johns Hopkins have turned their view of osteoarthritis inside out. Literally. Instead of seeing the painful degenerative disease as a problem primarily of the cartilage that cushions joints, they now have evidence that the bone underneath the cartilage is also a key player and exacerbates the damage. In a...

How will rainfall patterns across the tropical Indian and Pacific regions change in a future warming world? Climate models generally suggest that the tropics as a whole will get wetter, but the models don't always agree on where rainfall patterns will shift in particular regions within the tropics....

Since 2004, materials scientists and nanotechnology experts have been excited about a special of arrangement of atoms called a "coherent twin boundary" that can add enormous strength to metals like gold and copper. The CTBs are described as "perfect," appearing like a one-atom-thick plane in models and images. New research...

In 1990, the National Institute on Alcohol Abuse and Alcoholism issued guidelines that define low-risk drinking, which differ for men and women. New research shows that female college student drinkers exceed NIAAA guidelines for weekly drinking more frequently than their male counterparts. Fuente :...

An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers have figured it out. This can lead to a new medicine against...

Medical researchers have come up with a new approach for developing effective, topical antibacterial agents -- one that draws on a naturally occurring substance recognized since antiquity for its medicinal properties: clay. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/3...

Alcohol treatment interventions work best when patients understand and are actively involved in the process. A first-of-its-kind study looks at the interactive effects of smoking status and age on neurocognition in one-month-abstinent alcohol dependent (AD) individuals in treatment. Results show...
