Researchers at the University of Wisconsin-Madison have found a new way to accelerate a workhorse instrument that identifies proteins. The high-speed technique could help diagnose cancer sooner and point to new drugs for treating a wide range of conditions. Fuente :...

Scientists at the Marine Biological Laboratory have identified several genes linked to human neurological disorders, including Alzheimer's disease, Parkinson's disease and spinal cord injury, in the sea lamprey, a vertebrate fish whose whole-genome sequence is reported this week in the journal...

A new method of harvesting the sun's energy is emerging, thanks to scientists at UC Santa Barbara's departments of chemistry, chemical engineering, and materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust...

Researchers have shown that race and possibly genetics play a role in children's sensitivity to developing allergies. Researchers found: African-American children were sensitized to at least one food allergen three times more often than Caucasian children. African-American children with one...

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, researchers report. Their discovery has wide-ranging implications, they say, given the importance of this copying -- known as...

By analyzing data from DNA microarrays, scientists have completed a study that confirms the presence of four molecular classes of the disease and extends previous results by suggesting that there may be an underlying connection between the molecular classes and observed genomic events, some of...

Engineering researchers have created a new type of air-cleaning technology that could better protect human lungs from allergens, airborne viruses and ultrafine particles in the air. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/W...

For years researchers have been searching for a way to treat diabetics by reactivating their insulin-producing beta cells, with limited success. The "reprogramming" of related alpha cells into beta cells may one day offer a novel and complementary approach for treating type 2 diabetes. Treating...

Studies at the U.S. Department of Agriculture are shedding some light on the microbes that dwell in cattle manure -- what they are, where they thrive, where they struggle, and where they can end up. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/q...

A new cli­mate model pre­dicts an increase in snow­fall for Earth's polar regions and high­est alti­tudes, but an over­all drop in snow­fall for the globe, as car­bon diox­ide lev­els rise over the next century. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/v...

Running cockroaches start to recover from being shoved sideways before their dawdling nervous system kicks in to tell their legs what to do, researchers have found. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors'...

Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it. In new research, scientists mapped the complex interactions of proteins that control inflammation...

A study published February 21st in the New England Journal of Medicine (NEJM) provides clinical evidence of the safety and effectiveness of a new magnetic medical device to treat gastroesophageal reflux disease (GERD).

Researchers have now found stem cells inside the parasite that cause schistosomiasis, one of the most common parasitic infections in the world. These stem cells can regenerate worn-down organs, which may help explain how they can live for years or even decades inside their host. Fuente :...

Despite years of research, the genetic factors behind many human diseases and characteristics remain unknown, and has been called the "missing heritability" problem. A new study, however, suggests that heritability in humans may be hidden due only to the limitations of modern research tools, but...

Rocket attacks in Sderot, Israel significantly increase the likelihood of miscarriages, according to a new study. The study compared 1,341 pregnancies of women (exposed group) who resided in Sderot, an area exposed to frequent rocket fire, with 2,143 pregnancies of women who lived in Kiryat Gat...

Patients with HER2-positive breast cancer, a particularly aggressive form of breast cancer, now have a new, effective and less toxic therapeutic option. On Feb., 22, the U.S. Food and Drug Administration (FDA) approved the new treatment drug, Kadcyla (trastuzumab emtansine), also known as TDM-1,...

Sometimes the best discoveries come by accident. A team of researchers unexpectedly found the mechanism by which tiny single molecules spontaneously grow into centimeter-long microtubes by leaving a dish for a different experiment in the refrigerator. Fuente :...

Humans have at least two functional networks in their cerebral cortex not found in rhesus monkeys. This means that new brain networks were likely added in the course of evolution from primate ancestor to human. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/x...

The first scientific examinations of data recorded during a record-setting expedition have yielded new insights about the diversity of creatures that live and thrive in the cold, dark, and highly pressurized habitats of the world's deepest points and their vastly unexplored ecosystems. Fuente :...

When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps. The finding adds to the evidence that using toxins in the environment to medicate offspring may...

The commitment to reduce greenhouse gas emissions should be allocated based on countries’ historic responsibility for the emissions. This logic was recognized early on in climate negotiations. But the countries are still disputing how it should be interpreted and applied. Fuente :...
