For hundreds of years biologists have studied cells through the lens of a microscope. With a little help from a team of engineers, these scientists could soon be donning 3-D glasses in a home-theater-like lab to take their own fantastic voyage into the petri dish.

Scientists have developed dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and "smart" textiles; or propulsion systems for fist-sized "nanosatellites."

Skates have primitive colons. This may not sound like a big deal, but it is. The discovery could change scientific understanding of evolution, of how animals emerged from water to live on land.

When people are in a bad mood, they are more likely to actively search social networking sites like Facebook to find friends who are doing even worse than they are, a new study suggests. "One of the great appeals of social network sites is that they allow people to manage their moods by choosing who they want to compare themselves to," the authors said.

Scientists are analyzing the bottles of beer salvaged from the 1840s shipwreck found near the Åland Islands in 2010. Living bacteria found in the bottles were subject to further tests to find out how the cells had survived for so long in the wreck.
