Un equipo de investigadores confirma "al 100%" la existencia de vida en el lago Whillans, sepultado bajo 800 metros de hielo antártico. Científicos rusos ofrecen novedades sobre el agua recogida en el Vostok, otro lago subglacial ||| Fuente : http://esmateria.com/2013/03/03/eeuu-encuentra-cel...

A team of researchers from Johns Hopkins Children's Center, the University of Mississippi Medical Center and the University of Massachusetts Medical School describe the first case of a so-called "functional cure" in an HIV-infected infant. The finding, the investigators say, may help pave the way...

The powerful master regulatory transcription factor called Bcl6 is key to the survival of a majority of aggressive lymphomas, which arise from the B-cells of the immune system. The protein has long been considered too complex to target with a drug since it is also crucial to the healthy functioning...

An international group of researchers has discovered seven new regions of the human genome -- called loci -- that are associated with increased risk of age-related macular degeneration, a leading cause of blindness. Fuente : http://www.eurekalert.org/pub_releases/2013-03/nei...

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered how the most common genetic mutations in familial Parkinson's disease damage brain cells. The study, which published online today in the journal Nature Neuroscience, could also open up treatment possibilities...

A multi-institution group of researchers has found new candidate disease proteins for neurodegenerative disorders. They describe mutations in prion-like segments of two RNA-binding proteins are associated with a rare inherited degeneration disorder affecting muscle, brain, motor neurons and bone...

Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is...

UT MD Anderson scientists have found that many therapeutic cancer vaccines fail because they attract more T cells to the injection site than to the tumors. Replacing the adjuvant IFA with a saline solution reversed that, destroying tumors and minimizing injection site reaction. Fuente :...

A study led by St. Jude Children's Research Hospital has discovered mutations in two genes that lead to the death of nerve cells in amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, and related degenerative diseases. Fuente : http://www.eurekalert.org/pub_releases/2013-03/sjc...

Scientists have produced an instruction manual for the human genome that provides a framework to better understand the relationship between an individual's genetic make-up and their lifestyle. Fuente : http://www.eurekalert.org/pub_releases/2013-03/uom...

Building on earlier pioneering work by researchers at the University of California, San Diego, an international consortium of university researchers has produced the most comprehensive virtual reconstruction of human metabolism to date. Scientists could use the model, known as Recon 2, to identify...

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. Fuente : http://www.eurekalert.org/pub_releases/2013-03/uow...

An international group of researchers has discovered seven new regions of the human genome--called loci--that are associated with increased risk of age-related macular degeneration, a leading cause of blindness. Fuente : http://www.eurekalert.org/pub_releases/2013-03/bum...

An international group of investigators has identified seven new genetic regions associated with age-related macular degeneration (AMD), a common cause of blindness in older individuals. The findings, reported online March 3 in Nature Genetics, could point to new biological pathways and therapeutic...

A new technique for solving 'graph Laplacians' is drastically simpler than its predecessors, with implications for a huge range of practical problems. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/7...

Researchers have succeeded in gaining new insights into the causes of certain movement disorders and forms of dementia. Scientists were able to reproduce disease symptoms typical of amyotrophic lateral sclerosis and frontotemporal dementia in zebrafish. Fuente :...

As the U.S. national power-grid network becomes larger and more complex, achieving reliability across the network is increasingly difficult. Now scientists have identified conditions and properties that power companies can consider using to keep power generators in the desired synchronized state....

El médico francés critica la falta de compromiso del hombre más rico del mundo, pese a que el multimillonario acaba de conceder a su organización los 100.000 dólares de su Premio en Salud 2013 ||| Fuente : http://esmateria.com/2013/03/02/carlos-slim-ha-hec...

A new image from the Hubble Space Telescope may look like something from "The Lord of the Rings," but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The Archer), in the southern sky. Fuente :...

Postmenopausal women who have smoked are at much higher risk of losing their teeth than women who never smoked, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/6...

3-D printing lets anyone make almost anything with a simple machine and a roll of plastic filament. Now researchers have found a way to drive costs down even further by recycling empty milk jugs into filament. The process reduces landfill waste, saves on energy compared with traditional recycling, and makes 3-D printing and...

The world’s shark populations are experiencing significant declines with perhaps 100 million – or more - sharks being lost every year, according to a new study. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/p...

The removal of a genetic roadblock could improve the efficiency of converting adult cells into stem cells by 10 to 30 times, report scientists. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/K...

A new study demonstrates that bacteria can quickly and catastrophically clog medical devices by forming slimy ribbons that tangle and trap other cells. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/j...

Defective viruses, thought for decades to be essentially garbage unrelated to the transmission of a virus, now appear able to play a much more important role in the spread of disease, biologists show. Life scientists report for the first time a significant link between a defective virus and an increased rate of transmission...
