A study at Rhode Island Hospital has found that despite complications, patients co-infected with the pandemic 2009-2010 influenza A H1N1 and a second respiratory virus were not associated with worse outcomes or admission to the hospital's intensive care unit. The study is published online in the...

Mars has lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate, scientists report. Evidence has strengthened that Mars lost much of its original atmosphere by a process of gas escaping from the top of the atmosphere. Fuente :...

As the globe warms from rising atmospheric concentrations of greenhouse gases, more moisture in a warmer atmosphere will make the most extreme precipitation events more intense, new research shows. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/C...

Another innovative feature has been added to the world's first practical "artificial leaf," making the device even more suitable for providing people in developing countries and remote areas with electricity. It gives the leaf the ability to self-heal damage. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/f...

Researchers were able to selectively breed rats that exhibited traits of either extreme activity or extreme laziness. They say these rats indicate that genetics could play a role in exercise motivation, even in humans. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/L...

A new study offers new insights into how the nervous system processes hot and cold temperatures. The research found an interaction between the neural circuits that detect hot and cold stimuli: cold perception is enhanced when nerve circuitry for heat is inactivated.

A new study suggests that the way carbon moves from within a planet to the surface plays a big role in the evolution of a planet's atmosphere. Mars, which likely released much of its carbon as methane, might have been warm enough to support liquid water. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/g...
