Increasing temperatures and carbon dioxide levels in the world’s oceans may actually speed the growth of starfish, according to research published this week in the Proceedings of the National Academy of Sciences. The results contrast with previous findings of global warming’s negative effects on the five-armed fish’s relatives. [More] rss.sciam.com |

Nano-Risks: A Big Need for a Little Testing A decade ago the great worry about nanotechnology was that it could quite literally destroy the planet. As Sun Microsystems co-founder Bill Joy warned in his essay “Why the Future Doesn’t Need Us,” self-assembling nanobots could potentially spread out of our control (Mis-)programmed to replicate ad infinitum, these subsentient bots would spread across the landscape as a gray goo of devastation, consuming the earth and every unlucky creature who called it home.Nowadays we can only wish that our planet-dooming scenarios were so far-fetched. Our existential worries revolve around the all too immediate problems of global warming and disease, and nanotechnology--incorporated into improved solar panels, wind turbines or drug delivery mechanisms--could, if anything, emerge as an important tool to fight these threats.
