Sending Bugs into Space
These microbes, and not humans, may be the first species to inhabit another planet. A. cylindrica could be used by scientists to biologically ‘mine’ nutrients and metals from other planets to help human colonists. The bacteria, which are usually used to fertilize rice paddies, extracted metals from space rock analogues after surviving low Earth orbit, vacuum, heat, cold, and radiation.

The color green isn’t actually ‘green’
Synthetic green dyes, paints and pigments are made with a noxious cocktail of toxins and pollutants, making green an ironic symbol for the environmental movement.

Identify trees with your iPhone
A new iPhone app from the Arbor Day Foundation lets you identify trees on the go — and even geo-tag them to start a national tree inventory system.
A devastating tsunami triggered by the biggest earthquake on record in Japan looked set to kill at least 1,000 people along the northeastern coast on Friday after a wall of water swept away everything in its path.
Some supermassive black holes at the centers of galaxies seem to have voracious appetites, gobbling up material so fast that some of it escapes as jets of radiation. But others, including the black hole at the heart of our own Milky Way, are oddly dormant.
According to new research, published March 10 in the Astrophysical Journal (http://iopscience.iop.org/0004-637X/) , hungry black holes also generate wider swaths of radiation that drive strong winds of gas. As illustrated above, these winds push material out of reach, until there’s nothing near enough to fall into the black hole’s grasp. Starved, the black hole goes dormant.

one of the things i used to do is show readers cool infographics. it’s time to get back to that.
the purpose of an infographic is to take a handful of data and make it easily understandable in a visual way.
here’s one that shows some interesting information about Women & Stroke.
