Laser goes tubing for faster body-fluid tests
... and then they calculated corrections. It was easy enough
to inject the light by using the end of the tube opposite the laser. The resulting corrections made chemical predictions significantly more accurate. The team measured 11 chemicals in blood serum, including total protein, cholesterol, LDL and HDL l...
Joslin study indicates insulin receptors play a critical role in promoting islet growth
...es. In type 2 diabetes, the body doesn't produce enough
insulin and/or is unable to use insulin properly (insulin resistance). This form of diabetes usually occurs in people who are over 40, overweight, and have a family history of diabetes, although today it is increasingly occurring in younger people, i...
Flowers shape themselves to guide their pollinators to the pollen

Ewwwww! UCLA anthropologist studies evolution's disgusting side
..."The emotion allowed our ancestors to survive long enough
to produce offspring, who in turn passed the same sensitivities on to us." Across a series of subtle and ingenious studies, Fessler has managed to illuminate the ways in which disgust may have served to protect our ancestors during such biological...
International risk research strategy and funding needed for nanotech safety
