Engineers use 3-D gaming gear to give eye-opening look at cells in action

Posted: 03 Oct 2014 06:43 PM PDT

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.

Fast, cheap nanomanufacturing: Tiny conical tips fabricate nanoscale devices cheaply

Posted: 03 Oct 2014 10:54 AM PDT

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.

In a bad mood? Head to Facebook and find someone worse off

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.

Beer from 1840 shipwreck: Scientists developing new taste sensations for beer lovers from old beer
