It may be possible to treat cardiac hypertrophy and injury by using drugs that inhibit a protein called SIRT2.

A genetic duplication event during evolution allowed male wood tiger moths to have either yellow or white patterns on their wings.

A molecular pathway involving compounds found in processed foods and biogenic amines increases food intake and aging in the roundworm C. elegans.

Gene expression profiling of a diverse mouse population helps to decipher how a fat-rich diet contributes to inflammatory bowel disease.

Why do some inhibitors select the on-state in ERK2, a kinase that is involved in many signaling pathways in cells, whereas others bind to more than one conformation?

The larvae of an annelid worm use nitric oxide signalling to activate the neural pathways needed to swim away from the harmful ultraviolet light of the sun.

A range of experiments suggests that creatine, a molecule known for recycling ATP in muscle and brain tissue, may also function as a neurotransmitter in the central nervous system.

Individual species of bacteria and yeast present in the food of wild fruit flies work together to provide the nutrients needed for larval growth.

Experiments on tropical trees suggest that new mutations in plants are driven by age rather than number of cell divisions during growth.
