Injectable biomaterial could be used to manipulate organ behavior Posted: 01 Jul 2016 03:33 PM PDT Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists set out to see if they could design a material with all three of those properties. |
Frigate birds: In the air for months at a time Posted: 01 Jul 2016 09:07 AM PDT Frigate birds were already known for their ability to fly continuously for weeks without landing. A telemetric study of their trajectory and flight strategy has just revealed that they can remain airborne for over two months during their transoceanic migrations. |
Physicists find missing link between glass formation and crystallization Posted: 01 Jul 2016 06:55 AM PDT Glasses are neither fluids nor crystals. They are amorphous solids and one of the big puzzles in condensed matter physics. For decades, the question of how glass forms has been a matter of controversy. Is it because some regions freeze their thermal motion? Or is it because there are particles or clusters which do not fit to form a crystal? At least for the model system of hard spheres, researchers have now taken a major leap in reconciling these two opposing views. Using a clever combination of light scattering and microscopy, they were able to demonstrate that within a melt of hard spheres small compacted regions form comprising a few hundred spheres. |
Learn much you can, from Yoda’s spoken and subtitled discourse Posted: 01 Jul 2016 06:54 AM PDT The structural oddity of the speech pattern of the Star Wars character Master Yoda is probably one of the most instantly recognizable of all TV and film characters, even to those unfamiliar with the Star Wars series of films themselves. But how well does this speech 'oddity' translate into the accompanying sub-titles, and can we learn about how the structure of language can add weight to the perception of a character? |
Gelatin instead of the gym to grow stronger muscles Posted: 01 Jul 2016 06:39 AM PDT Scientists have devised a way to develop bigger, stronger muscle fibers. But instead of popping up on the bicep of a bodybuilder, these muscles grow on a tiny scaffold or 'chip' molded from a type of water-logged gel made from gelatin. |
What does the sperm whale say? Posted: 30 Jun 2016 07:20 AM PDT When a team of researchers began listening in on seven sperm whales in the waters off the Azores, they discovered that the whales' characteristic tapping sounds serve as a form of individual communication. But what are they actually saying? |
