A team of experts in neurocritical care, engineering, and informatics, with the Perelman School of Medicine at the University of Pennsylvania, have devised a new way to detect which stroke patients may be at risk of a serious adverse event following a ruptured brain aneurysm. This new, data-driven...

A team of pediatric neurosurgeons andneuroradiologists at the Johns Hopkins Children's Center has developed a way to minimize dangerous radiation exposure in children with a condition that requires repeat CT scans of the brain. The experts say they reduced exposure without sacrificing the...

When you shine UV through water polluted with certain organic chemicals and bacteria, the contaminants measurably absorb the UV light and then re-emit it as visible light. Many of today's more advanced devices for testing water are built to make use of this fluorescent property of pollutants; but...

Several newly identified markers could provide valuable insight to predict the risk of rupture abdominal aortic aneurysms (AAA), according to new research published in the October issue of the Journal of Nuclear Medicine. Imaging with PET/CT has shown that dense white blood cells in the outermost...

A research team led by a University of California, Riverside molecular plant pathologist has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables. The team discovered a novel virulence mechanism of Botrytis cinerea, a pathogen that can infect more...

Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood, Dartmouth researchers and their colleagues report in a study in the journal PLOS ONE. Fuente :...

The nearby star system Fomalhaut -- of special interest for its unusual exoplanet and dusty debris disk -- has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known. The results are described in a paper recently accepted for publication...

Polillas, escarabajos y pulgones alteran su comportamiento sexual en previsión de lluvias y fuertes vientos. La sensación de muerte inminente hace que los machos resuelvan la cópula más rápidamente para no resultar heridos. Estos cambios pueden perturbar a comunidades ecológicas completas. Fuente :...

People suffering from post-traumatic stress disorder (PTSD) face a greater risk of cardiovascular disease and death. A new study involving a comprehensive review of the medical literature shows that PTSD also increases an individual's risk of metabolic syndrome. What links these two disorders is...

Scientists from the Florida campus of The Scripps Research Institute have discovered some key features that explain just what turns on a protein that is considered to be a master regulator of how the human body uses and stores energy. Fuente : http://www.alphagalileo.org/ViewItem.aspx?ItemId=1...

In the October issue of GSA Today, Grant Young of the University of Western Ontario discusses the possible causes of the numerous glaciations that characterized the Neoproterozoic and concludes that a dramatic shift in Earth's climate may have occurred during the Ediacaran, in part due to a large...

Transgendered androphilic males were accepted in traditional hunter-gatherer cultures because they were an extra set of hands to support their families. Conversely, by investing in and supporting their kin, these males ensured that their familial line - and therefore also their own genetic make-up...

To aid in the decision making process, a study offers new information for those considering or needing surgery. For the first time, researchers assessed the economic and societal impact of ACL surgery in relation to the cost of the procedure and confirmed a significant cost savings to society over...

The second-most-common catch on Costa Rica's longline fisheries in the last decade was not a commercial fish species. It was olive ridley sea turtles. These lines also caught more green turtles than most species of fish. These findings and more indicate that the Costa Rican longline fishery...

Honey bees live in a world filled with danger in which predators seize them from the sky and wait to ambush them on flowers. Such fear drives bees to avoid food sources closely associated with predators and, interestingly, makes colonies of bees less risk-tolerant than individual bees, according to...

A team of engineers led by computer scientists has developed a new approach that marries computer vision and hardware optimization to sort cells up to 38 times faster than is currently possible. The approach could be used for clinical diagnostics, stem cell characterization and other applications....

While looking for novel pheromones that can control different instinctive mouse behaviors, researchers have discovered a pheromone found only in the tears of young mice. Their experiments showed that this molecule protects prepubescent mice from mating activity by adult male mice. The research...

Transgendered androphilic males were accepted in traditional hunter-gatherer cultures because they were an extra set of hands to support their families. This is according to an ethnographic study. The study reports that this "kin selection" is still at play in pro-transgender societies today....

Los roedores jóvenes se protegen del acoplamiento con machos adultos al segregar una feromona a través de sus lágrimas. El descubrimiento supone el primer paso hacia la comprensión de cómo un sistema sensorial, en este caso el olfativo, puede regular el comportamiento social. Fuente :...
