Studies Aim to Preempt Resistance to New Class of Cancer Drugs
August 12, 2008
Researchers have begun scouring cancer cells for potential sites of resistance against a promising new class of drugs currently under development. Their goal is to identify resistance mutations in the lab, before they arise in patients. More

Scientists Replicate Diseases in the Lab with New Stem Cell Lines
August 07, 2008
Researchers have converted cells from individuals with ten different diseases, including muscular dystrophy, juvenile diabetes, and Parkinson's disease, into stem cells. These cells will allow researchers to reproduce human tissue formation in a Petri dish as it occurs in individuals with any of the diseases. More

So Many Genes, So Little Time
August 01, 2008
Researchers have used new technology to pinpoint a critical gene mutation in worms in only a few weeks. It would have taken years for scientists using older technology to sift through the worm's DNA until they found the proverbial needle in the haystack. More

Newly Identified Genetic Deficiency in Children Illuminates Immune System Breakdown
July 31, 2008
Children with meningitis and other serious infections need swift treatment
with antibiotics to survive, but physicians have not been able to figure out
why the same microbe causes some children to get seriously ill and not
others. Now researchers have identified a genetic defect that makes these
children susceptible to attack by a certain type of bacteria, a finding that
will speed up the diagnosis and treatment of these sick children. More

Researchers Identify Drugs that Enhance Exercise Endurance
July 31, 2008
HHMI researchers have identified two drugs that mimic many of the physiological effects of exercise. The drugs increase the ability of cells to burn fat and are the first compounds that have been shown to enhance exercise endurance. More
