New resource opens the door for enzyme research

The European Molecular Biology Laboratory's European Bioinformatics Institute has launched the Enzyme Portal, a freely available resource for people who are interested in the biology of enzymes and proteins with enzymatic ...

A unique on-off switch for hormone production

Weizmann scientists have revealed a new kind of on-off switch in the brain for regulating the production of a main biochemical signal from the brain that stimulates cortisol release in the body.

New information on the waste-disposal units of living cells

Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and ...

Winning fights increases aggression, even in crickets

Winning a fight can raise aggressiveness, and a study of fighting crickets, published Dec. 21 in the online journal PLoS ONE, provides new insight into the biochemical mechanism that may be responsible.

Salt-tolerant crops show higher capacity for carbon fixation

Salt can have drastic effects on the growth and yield of horticultural crops; studies have estimated that salinity renders an about one-third of the world's irrigated land unsuitable for crop production. Imbalances in soil ...

Biologists learn how plants synthesize their growth hormone auxin

Biologists at the University of California, San Diego have succeeded in unraveling, for the first time, the complete chain of biochemical reactions that controls the synthesis of auxin, the hormone that regulates nearly all ...

Protein plays role in helping plants see light

Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between ...
