Why lizards have bird breath: Iguanas evolved one-way lungs surprisingly like those of birds

17/11/2014 | CIENCIA ON LINE
Biologists long assumed that one-way air flow was a special adaptation in birds driven by the intense energy demands of flight. But now scientists have shown that bird-like breathing also developed in green iguanas – reptiles not known for high-capacity aerobic fitness. The finding bolsters the...

The 'dirty' side of soap: Triclosan, a common antimicrobial in personal hygiene products, causes liver fibrosis and cancer in mice

17/11/2014 | CIENCIA ON LINE
Triclosan is an antimicrobial commonly found in soaps, shampoos, toothpastes and many other household items. Despite its widespread use, researchers report potentially serious consequences of long-term exposure to the chemical. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/g...

80 million bacteria sealed with a kiss

17/11/2014 | CIENCIA ON LINE
As many as 80 million bacteria are transferred during a 10 second kiss, according to research in journal Microbiome. The study also found that partners who kiss each other at least nine times a day share similar communities of oral bacteria. Fuente :...

Magic tricks created using artificial intelligence for the first time

17/11/2014 | CIENCIA ON LINE
Researchers working on artificial intelligence have taught a computer to create magic tricks. The researchers gave a computer program the outline of how a magic jigsaw puzzle and a mind reading card trick work, as well the results of experiments into how humans understand magic tricks, and the...

'Not just a flavoring: Menthol, Nicotine, Combined Desensitize Airway Receptors

16/11/2014 | CIENCIA ON LINE
Menthol doesn't just act as a flavoring, but has a pharmacologic impact, a new study suggests. The researchers say menthol acts in combination with nicotine to desensitize receptors in lungs' airways that are responsible for nicotine's irritation. Though not a focus of the work, the findings are...

Half of STEMI heart attack patients may have additional clogged arteries

16/11/2014 | CIENCIA ON LINE
A blocked artery causes a deadly kind of heart attack known as STEMI, and a rapid response to clear the blockage saves lives. But in more than half of cases studied, one or both of the patient’s other arteries were also obstructed, raising questions about whether and when additional procedures...

High Mortality Associated with STEMI Heart Attacks That Occur in Hospitalized Patients

16/11/2014 | CIENCIA ON LINE
Researchers have confirmed their surprising earlier finding: Patients who suffer a STEMI heart attack while while in the hospital for something else are more likely to die than patients who have the same type of heart attack outside the hospital. Fuente :...

Rosetta's comet lander: Pioneering Philae completes main mission before hibernation

15/11/2014 | CIENCIA ON LINE
Rosetta's lander has completed its primary science mission after nearly 57 hours on Comet 67P/Churyumov-Gerasimenko. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/p...

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

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 :...
