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

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
