Morphing robots and shape-shifting sculptures: Origami-inspired design merges engineering, art

Posted: 21 May 2012 01:41 PM PDT

Researchers have shown how to create morphing robotic mechanisms and shape-shifting sculptures from a single sheet of paper in a method reminiscent of origami, the Japanese art of paper folding.

Method to strengthen proteins with polymers

Posted: 21 May 2012 01:41 PM PDT

Scientists have synthesized polymers to attach to proteins in order to stabilize them during shipping, storage and other activities. The study findings suggest that these polymers could be useful in stabilizing protein formulations.

Totally RAD: Bioengineers create rewritable digital data storage in DNA

Posted: 21 May 2012 01:37 PM PDT

Scientists have devised a method for repeatedly encoding, storing and erasing digital data within the DNA of living cells. In practical terms, they have devised the genetic equivalent of a binary digit -- a "bit" in data parlance.

Stunning view of Lyrids and Earth at night

Posted: 21 May 2012 12:33 PM PDT

On the night of April 21, the 2012 Lyrid meteor shower peaked in the skies over Earth. While NASA allsky cameras were looking up at the night skies, astronaut Don Pettit aboard the International Space Station trained his camera on Earth. Video footage from that night is now revealing breathtaking images of Earth with meteors ablating -- or burning up -- in the atmosphere.

Hubble spies edge-on beauty: Galaxy NGC 891

Posted: 21 May 2012 12:31 PM PDT

Visible in the constellation of Andromeda, NGC 891 is located approximately 30 million light-years away from Earth. The NASA/ESA Hubble Space Telescope turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern half.

Cell network security holes revealed, with an app to test your carrier

Posted: 21 May 2012 10:28 AM PDT

Popular firewall technology designed to boost security on cellular networks can backfire, unwittingly revealing data that could help a hacker break into Facebook and Twitter accounts, a new study shows.

From lemons to lemonade: Using carbon dioxide to make carbon nitride

Posted: 21 May 2012 08:56 AM PDT

Scientists have discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it creates some useful compounds to boot.

Cloak of invisibility: Engineers use plasmonics to create an invisible photodetector

Posted: 21 May 2012 07:46 AM PDT

Engineers have for the first time used "plasmonic cloaking" to create a device that can see without being seen -- an invisible machine that detects light. It is the first example of what the researchers describe as a new class of devices that controls the flow of light at the nanoscale to produce both optical and electronic functions.

Hall effect at the speed of light: How can you demonstrate relativistic effects with your mobile phone?

Posted: 21 May 2012 07:29 AM PDT

The relativistic Hall effect describing objects rotating at speeds comparable with the speed of light has now been reported.

Diamond used to produce graphene quantum dots and nano-ribbons of controlled structure

Posted: 17 May 2012 04:31 PM PDT

Researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics.
