Antartica’s Southern Ocean, a crucial "carbon sink" into which 15 percent of the world’s excess carbon dioxide flows, is reaching saturation and soon may be unable to absorb more — a deeply troubling development, the journal Science reported Thursday.

Pasta tastes like pasta – with or without a spiral. But when you jump to the nanoscale, everything changes: carbon nanotubes and nanofibers that look like nanoscale spiral pasta have completely different electronic properties than their non-spiraling cousins. Engineers at UC San Diego, and Clemson University are studying these differences in the hopes of creating [...]

The number of stars that appear to be orbited by Earth-like planets increases on an almost daily basis. But if that is the case, where is everybody? Why are there no signs of their existence? Why does SETI [...]
