When you look at your body in the mirror, most of what you consider to be “you” actually isn’t you, at least not in a biological sense.
Biotech Startup uBiome Aims To Sequence The Bacteria That Call Our Bodies Home
Software can transform a computer from a word processor to a number cruncher to a video telephone. But the underlying hardware is unchanged. Now, a type of transistor that can be switched with magnetism instead of electricity could make circuitry malleable too, leading to more efficient and reliable gadgets, from smart phones to satellites.

One Astrobiologist's Plan to Save the Search for Alien Life | Wired Science
Jupiter’s moon Europa hides an ocean of water beneath its icy crust that might harbor extraterrestrial life. Unfortunately, big dollar signs have kept alive the fictional decree in Arthur C.
Modern Earth is wet and temperate (last week's heat wave aside), but the early Earth was molten and hostile, meaning water and other volatile substances like hydrogen and nitrogen compounds must have been deposited after formation. The likely culprits are comets—full of water ice and organic compounds—and meteorites, which were likely more water-laden in the early days of the Solar System. Knowing exactly where Earth's water and organic molecules originated would reveal a great deal about our planet's history and help us understand the environment in which life arose.
Meteorites, not comets, may have brought water to Earth
The Neuroscience of Creativity and Insight | Think Tank
The Internet has a terrible habit of misquoting Einstein on energy and creativity until he sounds like he’s the author of , not the theory of relativity. Here’s something he actually did say . Describing the effect of music on his inner life, he told a friend: “When I examine myself and my methods of thought, I come close to the conclusion that the gift of imagination has meant more to me than any talent for absorbing absolute knowledge.”
