Rosetta's comet lander: How (and where) is Philae?

14/11/2014 | CIENCIA ON LINE
The current status of Rosetta's lander Philae was discussed live during a Google Hangout this afternoon, together with scientists and engineers from the mission teams at ESA and partner agencies. The teams are very happy about the lander and the successful functioning of all instruments that were...

Do spinal cord injuries cause subsequent brain damage?

14/11/2014 | CIENCIA ON LINE
Spinal cord injuries can cause widespread and sustained brain inflammation that leads to progressive loss of nerve cells, with associated cognitive problems and depression, researchers have found for the first time. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/j...

Scientists employ satellite tags to solve whale-sized mystery

14/11/2014 | CIENCIA ON LINE
For the first time, scientists working in the waters of Patagonia are using satellite tags to remotely track southern right whales from their breeding/calving grounds in the sheltered bays of Península Valdés, Argentina, to unknown feeding grounds somewhere in the western South Atlantic.

Crucial mechanism driving colliding epidemics of smoking, TB unlocked by scientists

14/11/2014 | CIENCIA ON LINE
TB is an infectious disease that kills 1.5 million people each year and smoking is the biggest driver of the global TB epidemic. Medical scientists have unlocked the mechanism underlying the connection between smoking and Tuberculosis. This discovery will considerably strengthen anti-smoking...

New imaging technique identifies receptors for targeted cancer therapy

14/11/2014 | CIENCIA ON LINE
A fluorescence imaging technique has been developed that can more accurately identify receptors for targeted cancer therapies without a tissue biopsy. "Accurately determining the population of protein receptors in a tumor available for targeting by molecular therapies or diagnostic imaging agents...

Seismic hazard in the Puget Lowland, Washington state, USA

14/11/2014 | CIENCIA ON LINE
Seismic hazards in the Puget Lowland of northwestern Washington include deep earthquakes associated with the Cascadia subduction zone and shallow earthquakes associated with crustal faults across the region. New research establishes not only that one of the more prominent crustal faults, the...

'Topological insulators' promising for spintronics, quantum computers

14/11/2014 | CIENCIA ON LINE
Researches have uncovered 'smoking-gun' evidence to confirm the workings of an emerging class of materials that could make possible 'spintronic' devices and practical quantum computers far more powerful than today's technologies. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/N...

Chemists develop porous molecules that bind greenhouse gases

14/11/2014 | CIENCIA ON LINE
Chemistry researchers have developed a molecule that assembles spontaneously into a lightweight structure with microscopic pores capable of binding large quantities of several potent greenhouse gases. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/K...

Intergalactic 'wind' is stripping galaxies of star-forming gas

13/11/2014 | CIENCIA ON LINE
Astronomers have provided the first direct evidence that an intergalactic 'wind' is stripping galaxies of star-forming gas as they fall into clusters of galaxies. The observations help explain why galaxies found in clusters are known to have relatively little gas and less star formation when...

The science behind total recall: New player in brain function and memory

13/11/2014 | CIENCIA ON LINE
Is it possible to change the amount of information the brain can store? Maybe, according to a new international study. The research has identified a molecule that puts a brake on brain processing and when removed, brain function and memory recall is improved. Fuente :...

Investigational medication used to resolve life-threatening seizures in children

13/11/2014 | CIENCIA ON LINE
In its first clinical application in pediatric patients, an investigational medication has been found to effectively treat children with life-threatening and difficult-to-control epileptic seizures without side effects, according to a research report. Fuente :...

Atomic timekeeping, on the go: New approach may enable more stable and accurate portable atomic clocks

13/11/2014 | CIENCIA ON LINE
What time is it? The answer, no matter what your initial reference may be -- a wristwatch, a smartphone, or an alarm clock -- will always trace back to the atomic clock. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/s...

Genetic tweak gave yellow fever mosquitoes a nose for human odor

13/11/2014 | CIENCIA ON LINE
One of the world's deadliest mosquitoes sustains its taste for human blood thanks in part to a genetic tweak that makes it more sensitive to human odor, according to new research. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/D...

Predicting US Army suicides after hospital discharge

13/11/2014 | CIENCIA ON LINE
Some Army suicides can be predicted with enough accuracy to justify implementing preventive interventions in patients at high risk, experts say. The study looked at 53,769 regular Army soldiers during the 12-month period following their discharge from a psychiatric facility during 2004 to 2009....

Secrets in stone: Art historian cracks the code of an ancient temple

13/11/2014 | CIENCIA ON LINE
For 13 centuries, the Virupaksha Temple in Pattadakal has been one of the most recognizable landmarks in Indian art —- a towering layer cake of elaborate, hand-carved friezes populated by a bevy of Hindu deities and symbols. Now a professor of Asian art history has shown that these figures are...

Twisted light waves sent across Vienna

12/11/2014 | CIENCIA ON LINE
A group of researchers from Austria have sent twisted beams of light across the rooftops of Vienna. It is the first time that twisted light has been transmitted over a large distance outdoors, and could enable researchers to take advantage of the significant data-carrying capacity of light in both...

Piecing together signaling pathway leading to obesity

11/11/2014 | CIENCIA ON LINE
A team of researchers has now drawn connections between known regulators of body mass, pointing to possible treatments for obesity and metabolic disorders. As scientists probe the molecular underpinnings of why some people are prone to obesity and some to leanness, they are discovering that weight...

Key protein can reduce severity of disease equivalent to multiple sclerosis in mice

11/11/2014 | CIENCIA ON LINE
Researchers have identified a key protein that is able to reduce the severity of a disease equivalent to multiple sclerosis in mice. This molecule, Del-1, is the same regulatory protein that has been found to prevent inflammation and bone loss in a mouse model of gum disease. Fuente :...

First analysis of new human glucose disorder revealed

11/11/2014 | CIENCIA ON LINE
Glycogen storage disorders are metabolic conditions that manifest in the first years of life. This inability to process and store glucose can be difficult to diagnose. Now, researchers who have studied enzymes involved in metabolism of bacteria have cataloged the effects of abnormal enzymes...
