Un estudio ha precisado la antigüedad de los restos humanos neandertales de la cueva de El Sidrón (Asturias), sobre la que estudios anteriores proporcionaron mediciones poco exactas. La aplicación de un pretratamiento para reducir la contaminación por carbono moderno ha conseguido disminuir el...

A new look at conditions after a Manhattan-sized asteroid slammed into a region of Mexico in the dinosaur days indicates the event could have triggered a global firestorm that would have burned every twig, bush and tree on Earth and led to the extinction of 80 percent of all Earth's species, says a...

"These findings highlight the limitations of basing mealtime insulin dosing for type 1 diabetes solely on carbohydrate intake," says Dr. Wolpert. "We need to consider fat as well as carbohydrates in insulin dosing calculations as well as in nutritional recommendations." Fuente :...

Beneath the ocean floor is a desolate place with no oxygen and sunlight. Yet microbes have thrived in this environment for millions of years. Scientists have puzzled over how these microbes survive, but today there are more answers. Fuente : http://www.eurekalert.org/pub_releases/2013-03/uot...

The odds of developing breast cancer increase for women taking hormone replacement therapy to avoid the effects of menopause. New research by University of Missouri scientist Salman Hyder may lead to treatments for breast cancers associated with taking these synthetic hormones. Hyder found that...

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, says a key protein in Schwann cells performs a critical, perhaps overarching, role in regulating the recovery of peripheral nerves after injury. The discovery has implications for...

Mathematical models can be used to study the spread of technological innovations among individuals connected to each other by a network of peer-to-peer influences, such as in a physical community or neighborhood. One such model was introduced in a paper published yesterday in the SIAM Journal on Applied Dynamical Systems....

Researchers at Moffitt Cancer Center, including Center Director Thomas A. Sellers, Ph.D., M.P.H., and 17 other co-authors, have discovered four new regions of the genome that influence the risk for developing ovarian cancer, according to two Moffitt-led studies published in the March 27 issue of the journals Nature Genetics...

Researchers have been able to provide one answer as to why males in many species still provide paternal care, even when their offspring may not belong to them. The study finds that, when the conditions are right, sticking around despite being "cuckolded" actually turns out to be the most successful...

It's been more than fifty years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or "mating type," is determined; now they do. Fuente :...

Scientists are getting closer to a Chagas disease vaccine, something many believed impossible only 10 years ago. New research has resulted in a safe vaccine candidate that is simple to produce and shows a greater than 90 percent protection rate against chronic infection in mice. Fuente :...

While humans and birds must learn to vocalize, a neurophysiologist has found that deaf male mice will vocalize to females the same way as hearing mice. The finding points the way to a more finely focused, genetic tool for teasing out the mysteries of speech and its disorders. Fuente :...

A psychological experiment known as "the marshmallow test" has captured the public's imagination as a marker of self control. This test shows how well children can delay gratification, a trait that has been shown to be as important to scholastic performance as traditional IQ. New research suggests,...

Existing Lyme disease tests assess the presence of antibodies, which take weeks to form after the initial infection and persist after the infection is gone. Now, a nanotechnology-inspired technique may lead to diagnostics that can detect the organism itself. Fuente :...

A scientific review of 63 published studies affirms that putting small amounts of purified grasses, ragweed, dust mites, pollen and mold, in liquid drops under the tongue is a safe and effective alternative to weekly injections of those allergens or the use of other medications, in treating...

Según una investigación publicada hoy en PLOS Biology, los machos tienden a desentenderse de sus crías si piensan que su pareja les ha sido infieles. Un comportamiento así plantea sus riesgos porque podrían estar abandonando a su propia descendencia. Fuente :...

Researchers have uncovered an obstacle to the cone-guided approach to fast-ignition fusion energy through computer simulations. Scientists found electric fields that build up on the cone's edge reduce the number of energetic electrons being directed by laser beams toward the targeted fuel. Fuente :...

When it officially came online at the San Diego Supercomputer Center in early January 2012, Gordon was instantly impressive. In one demonstration, it sustained more than 35 million input/output operations per second -- then, a world record. Fuente :...
