| DNA building blocks can be made in space, NASA evidence suggests Posted: 08 Aug 2011 07:06 PM PDT NASA-funded researchers have evidence that some building blocks of DNA, the molecule that carries the genetic instructions for life, found in meteorites were likely created in space. The research gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by meteorite and comet impacts assisted the origin of life.  |
| Light speed hurdle to invisibility cloak overcome by undergraduate Posted: 08 Aug 2011 05:25 PM PDT An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also has the ability to slow down light.  |
| Like superman's X-Ray vision, new microscope reveals nanoscale details Posted: 08 Aug 2011 12:41 PM PDT Physicists have developed a new kind of X-ray microscope that can penetrate deep within materials like Superman's fabled X-ray vision and see minute details at the scale of a single nanometer, or one billionth of a meter.  |
| You can count on this: Math ability is inborn, new research suggests Posted: 08 Aug 2011 12:24 PM PDT We accept that some people are born with a talent for music or art or athletics. But what about mathematics? Do some of us just arrive in the world with better math skills than others? It seems we do, at least according to the results of a new study. The research indicates that math ability in preschool children is strongly linked to their inborn and primitive "number sense," called an "Approximate Number System" or ANS.  |
| Posted: 08 Aug 2011 05:36 AM PDT Researchers can now watch molecules move in living cells, literally millisecond by millisecond, thanks to a new microscope developed by scientists in Germany. The new technique provides insights into processes that were so far invisible.  |
