Discovery alters long standing concept of fixed protein structure

The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life.

Zebrafish enables cell regeneration studies to help understand, treat human disease

One aquarium fish's uncanny ability to regenerate essentially any cell type has given scientists a way to mimic cell loss that occurs in diseases such as Parkinson's and diabetes then watch how the fish make more of them.

Wine harder on the brain than beer

Scientists say wine damages the brain more than beer or spirits, because it particularly affects the hippocampus, the part of the brain associated with memory and spatial awareness.

Gene network disrupted by obesity

According to new research an entire network of genes in the body is disrupted by overeating and this not only causes obesity, but also diabetes and heart disease.
