New injectable hydrogel accelerates healing of deep wounds

Any minor cut or scrape sets the body's natural healing process in motion. However, deep wounds are far more vulnerable to bacterial infection and the accumulation of harmful molecules called reactive oxygen species (ROS) that damage cells and disrupt normal repair mechanisms.

Taste preference genes drive overeating and metabolic disease risk

Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty tastes not only tend to eat more of these foods but also have a higher risk of obesity and type 2 diabetes as a result.

Primate study reveals molecular basis of red-green color vision

Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green, or blue light.
