Mouse study points to understanding, enhancing pain therapy
HHMI researchers have knocked out a gene that muffles the painkilling signal of morphine, yielding mice that can tolerate pain for longer periods of time, even while receiving lower doses of morphine.

Engineered mice point to new target for pain relief
Duke University Medical Center scientists have discovered a biological mechanism in mice that prolongs morphine's painkilling effects.

Chromosome centers defined and sequenced for model plant
Researchers have defined the centromeres of the five chromosomes of Arabidopsis thaliana, the primary model for plant genetics.

Study identifies new tumor suppressor gene in Li-Fraumeni syndrome
A research team based at the Massachusetts General Hospital has identified a novel gene that is mutated in some families that have Li-Fraumeni syndrome or a closely related condition but do not have mutations in p53, the gene most closely associated with Li-Fraumeni. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
