Paying extra bucks to "go green" in a hybrid car may pay off in self-esteem and image for older drivers, as well as give a healthy boost to the environment, according to a Baylor University study. Fuente : http://www.eurekalert.org/pub_releases/2013-10/bu-...

Research conducted through Princeton University found that erratic rainfall -- which could become more irregular as a result of climate change -- could be detrimental to animals that migrate with the dry-wet seasonal cycle. The researchers studied the annual mating migration of the land-dwelling...

In the land of 10,000 lakes, one lake has been the starting place for research with implications for big lakes around the world. According to a study published online this week in Science, University of Minnesota researchers, building from studies of nitrogen levels in Lake Superior, uncovered a...

"Sticks and stones may break my bones, but words will never hurt me," goes the playground rhyme that's supposed to help children endure taunts from classmates. But a new study suggests that there's more going on inside our brains when someone snubs us -- and that the brain may have its own way of...

"Cataplexy is characterized by muscle paralysis during cognitive awareness, but we didn't understand how this happened until now, said John Peever of the University of Toronto's Department of Cell & Systems Biology. "We have shown that the neuro-degeneration of the brain cells that synthesize the...

Research conducted by the National Geographic Genographic Project, a multi-year global initiative that uses DNA to map the history of human migration, is helping unravel the timing and source of human settlement in Central Europe. Fuente : http://www.eurekalert.org/pub_releases/2013-10/ngs...

Thirty-eight US national parks are experiencing "accidental fertilization" at or above a critical threshold for ecological damage. Unless significant controls on ammonia emissions are introduced at a national level, little improvement is likely between now and 2050. Fuente :...

A discovery at Rice University aims to make vehicles that run on compressed natural gas more practical and may also enhance food packaging. Fuente : http://www.eurekalert.org/pub_releases/2013-10/ru-...

A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment. The hybrid device combines a microbial fuel cell (MFC) and a type of solar cell called a photoelectrochemical cell (PEC)....

“Toda la región está bajo control, pero hay que tener cuidado en el centro de la ciudad”. El consejo de este miliciano kurdo a la entrada de Qamishli, 600 kilómetros al noreste de Damasco, apunta a brechas inesperadas en la relativa estabilidad del Kurdistán sirio. Literalmente incrustada contra la...

Researchers have tripled the output power of a compact, room-temperature terahertz source, a breakthrough that could lead to advances in homeland security, industrial applications, and space research. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/B...

Calculations show carbyne, a simple chain of carbon atoms, may be the strongest material of all. Carbyne will be the strongest of a new class of microscopic materials if and when anyone can make it in bulk. If they do, they'll find carbyne nanorods or nanoropes have a host of remarkable and useful...

An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago -- a newborn...

Astronomers have captured an image of an unusual free-floating planet. As the object has no host star, it can be observed and examined much easier than planets orbiting stars, promising insight into the details of planetary atmospheres.

Using mice, lab-grown cells and clues from a related disorder, researchers have greatly increased understanding of the causes of systemic sclerosis, showing that a critical culprit is a defect in the way certain cells communicate with their structural scaffolding. They say the new insights point...

The seesaw variability of global temperatures often engenders debate over how seriously we should take climate change. But within 35 years, even the lowest monthly dips in temperatures will be hotter than we've experienced in the past 150 years, according to a new and massive analysis of all...

Researchers have come one step closer to understanding unstable atomic nuclei. Scientists have now provided evidence for a new nuclear magic number in the unstable, radioactive calcium isotope 54Ca. They show that 54Ca is the first known nucleus with 34 neutrons (N) where N = 34 is a magic number. ...

Egoism and narcissism appear to be on the rise in our society, while empathy is on the decline. And yet, the ability to put ourselves in other people's shoes is extremely important for our coexistence. Scientists have discovered that our own feelings can distort our capacity for empathy. This...

Researchers, working with elderly mice, have determined that combining gene therapy with an extra boost of the same stem cells the body already uses to repair itself leads to faster healing of burns and greater blood flow to the site of the wound. Fuente :...

Dentro de 35 años, incluso las mayores caídas de temperaturas serán más altas que las experimentadas en los pasados 150 años, según un nuevo y masivo análisis de modelos climáticos que publica la revista Nature. Este trabajo indica, por primera vez, que estos cambios serán más acusados en algunas...

Este martes se ha inaugurado en Puertollano (Ciudad Real) el nuevo centro de integración y operaciones de satélites de Elecnor Deimos. En sus instalaciones se ha completado el satélite Deimos-2 de observación de la Tierra, que a partir de 2014 facilitará imágenes a gran resolución para servicios de...

Con el reciente intento fallido del ensayo HVTN 505, ya son dos veces en las que se comprueba la no utilidad del adenovirus 5 para el desarrollo de vacunas preventivas. La primera vez fue con los ensayos STEP y Phambili, parados en 2007 por un aumento del riesgo de infección del VIH. Hoy, la...

Egoism and narcissism appear to be on the rise in our society, while empathy is on the decline. And yet, the ability to put ourselves in other people’s shoes is extremely important for our coexistence.

Investigators who studied a group of recreational marathon runners have established that strenuous exercise such as running a marathon can damage the heart muscle. Although they found the effect is temporary and reversible, they warn that these effects are more widespread in less fit distance runners and that recreational...

Over a quarter of UK patients treated for growth hormone-producing tumours do not achieve ‘safe’ growth hormone (GH) levels, according to a 30 year UK multi-centre study of clinical management of the rare disease acromegaly.

During the past decades the findings of scientific ocean drilling expeditions have fundamentally changed the way we look at our blue planet. Today we have a much better grasp of how processes like earthquakes and tsunamis develop; ocean drilling made it possible to prove the theory of plate tectonics and we know a lot more...

Malcolm Wallace siempre supo cuál sería su destino. A los 19 años construyó su propio invernadero en la finca de su padre en Dominica, y allí plantó lechugas, pimientos dulces, tomates y pepinos. “Era una actividad muy lucrativa y realmente gané dinero”, relata Wallace, hoy científico del Instituto...
