A major step forward towards drought tolerance in crops

When a plant encounters drought, it does its best to cope with this stress by activating a set of protein molecules called receptors. These receptors, once activated, turn on processes that help the plant survive the stress.

A chaperone for the 'guardian of the genome'

The protein p53 plays an essential role in the prevention of cancer by initiating the controlled death of a cell with damaged genes which is in danger to transform into a cancerous cell. The heat shock protein Hsp90, in turn, ...

Biologists identify a new clue into cellular aging

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy ...

Research spawns new discoveries showing how crops survive drought

(PhysOrg.com) -- Breakthrough research done earlier this year by a plant cell biologist at the University of California, Riverside has greatly accelerated scientists' knowledge on how plants and crops can survive difficult ...

Prion discovery gives clue to control of mass gene expression

The discovery in common brewer's yeast of a new, infectious, misfolded protein -- or prion -- by University of Illinois at Chicago molecular biologists raises new questions about the roles played by these curious molecules, ...

Obesity: Reviving the promise of leptin

(PhysOrg.com) -- The discovery more than a decade ago of leptin, an appetite-suppressing hormone secreted by fat tissue, generated headlines and great hopes for an effective treatment for obesity. But hopes dimmed when it ...
