New study singles out factors linked to cognitive deficits in type 2 diabetes
Older adults with diabetes who have high blood pressure, walk slowly or lose their balance, or believe they're in bad health, are significantly more likely to have weaker memory and slower, more rigid cognitive processing than those without these problems, according to a new study.

Misfolded neural proteins linked to autism disorders
Scientists have identified misfolding and other molecular anomalies in a key brain protein associated with autism spectrum disorders.

Flying fish glide as well as birds, researchers find
How well do flying fish fly? This is the question that puzzled researchers in South Korea. Measuring aerodynamic forces on dried darkedged-wing flying fish in a wind tunnel, they discovered that flying fish glide better than insects and as well as birds. The fish also derive an aerodynamic advantage from gliding close to the water's surface to cover distances as great as 400 meters.

Yikes! Sensor measures yoctonewton forces fast
Physicists have used a small crystal of ions (electrically charged atoms) to detect forces at the scale of yoctonewtons. Measurements of slight forces -- one yoctonewton is equivalent to the weight of a single copper atom on Earth -- can be useful in force microscopy, nanoscale science, and tests of fundamental physics theories.
