| A complete solution for oil-spill cleanup Posted: 03 Oct 2012 12:09 PM PDT Scientists are describing what may be a "complete solution" to cleaning up oil spills -- a super-absorbent material that sops up 40 times its own weight in oil and then can be shipped to an oil refinery and processed to recover the oil.  |
| Graphene nanopores can be controlled: Less costly ways of sequencing DNA Posted: 03 Oct 2012 11:14 AM PDT Engineers have used advanced techniques to make the material graphene small enough to read DNA. Shrinking the size of a graphene pore to less than one nanometer opens the possibility of graphene as a low-cost tool to sequence DNA.  |
| NASA's infrared observatory measures expansion of universe Posted: 03 Oct 2012 10:48 AM PDT Astronomers using NASA's Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant, or the rate at which our universe is stretching apart.  |
| Surprising black hole discovery changes picture of globular star clusters Posted: 03 Oct 2012 10:21 AM PDT An unexpected discovery is forcing scientists to rethink their understanding of the environment in globular star clusters, tight-knit collections containing hundreds of thousands of stars. The astronomers were studying a globular cluster called Messier 22 (M22), a group of stars more than 10,000 light-years from Earth. They hoped to find evidence of a rare type of black hole in the cluster's center called an intermediate-mass black hole, which is more massive than those larger than the Sun's mass, but smaller than the supermassive black holes found at the cores of galaxies. However, they found something very surprising - two smaller black holes, which is unusual because most theorists say there should be at most one black hole in the cluster.  |
| Sea urchin's spiny strength revealed Posted: 03 Oct 2012 06:46 AM PDT For the first time, a team of Australian engineers has modelled the microscopic mechanics of a sea urchin's spine, gaining insight into how these unusual creatures withstand impacts in their aquatic environment.  |
| New 3-D camera for space missions Posted: 03 Oct 2012 05:25 AM PDT A new 3-D camera has been developed for space missions. Researchers are now completing a study identifying alternatives to the cameras currently deployed on spacecrafts and space rovers.  |
