Infection control experts at The Johns Hopkins Hospital have found that a combination of robot-like devices that disperse hydrogen peroxide vapor into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bacteria.


Of special note, researchers say, was that enhanced cleaning with the vapor reduced by 80 percent a patient's chances of becoming colonized by a particularly aggressive and hard-to-treat bacterium, vancomycin-resistant enterococci (VRE). ...

We asks ourselves this a lot, so do stem cells!

Check out this amazing image of am urodid moth cocoon. According to entomologist and Amazon explorer Phil Torres, It has a really beautiful woven lattice structure that hangs about a foot below a leaf on a thin silk string.

This is an unusual structure because the pupa, resting inside the cocoon, seems fairly exposed to the elements. The hanging likely helps to prevent predation from ants, and the bright orange color may serve as an aposematic signal to predators to prevent it from getting eaten. The tube part at the bottom is the 'escape hatch' from which it eventually will exit as an adult moth. There is not a lot of research that has been done on the evolutionary origin structure - this is one of the many mysteries of the Amazon you can c ...

The lines over the circles are colour coded. Notice the single red line and 3 blue lines representing 13 groups together while the single green and 2 black lines take their own group. Simply draw your first group of lines in one direction then your second group of lines going over the first, count the groups of intersections and there\'s your answer.

In 1995 a group of NASA scientists repeated and refined some earlier tests on the effect that various drugs have on the web building abilities of the common garden spider. They tested the the effect of caffeine, benzedrine, marijuana and chloral hydrate and as you can see the results were pretty extreme!

Sometimes, the Sun itself seems to dance. On just this past New Years Eve, for example, NASAs Sun-orbiting Solar Dynamic Observatory spacecraft imaged an impressive prominence erupting from the Suns surface. The dramatic explosion was captured in ultraviolet light in the above time lapse video covering four hours. Of particular interest is the tangled magnetic field that directs a type of solar ballet for the hot plasma as it falls back to the Sun. The scale of the disintegrating prominence is huge -- the entire Earth would easily fit under the flowing curtain of hot gas. A quiescent prominence typically lasts about a month, and may erupt in a Coronal Mass Ejection expelling hot gas into the Solar System. The energy mechanism that creates a ...
