Immune cell 'survival' gene key to better myeloma treatments
Scientists have identified the gene essential for survival of antibody-producing cells, a finding that could lead to better treatments for diseases where these cells are out of control, such as myeloma and chronic immune disorders.

Plant scientists at CSHL demonstrate new means of boosting maize yields
A team of plant geneticists at Cold Spring Harbor Laboratory has successfully demonstrated what it describes as a

Growth factor aids stem cell regeneration after radiation damage
Epidermal growth factor has been found to speed the recovery of blood-making stem cells after exposure to radiation, according to Duke Medicine researchers.

Researchers discover mutations linked to relapse of childhood leukemia
After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer -- the first time anyone has linked the disease's reemergence to specific genetic anomalies.

DNA reveals mating patterns of critically endangered sea turtle
New University of East Anglia research into the mating habits of a critically endangered sea turtle will help conservationists understand more about its mating patterns.

Recreating natural complex gene regulation
By reproducing in the laboratory the complex interactions that cause human genes to turn on inside cells, Duke University bioengineers have created a system they believe can benefit gene therapy research and the burgeoning field of synthetic biology.

Changes to DNA on-off switches affect cells' ability to repair breaks, respond to chemotherapy
Penn cancer biologists have found a key determinant in the balance between two proteins, BRCA1 and 53BP1, in the DNA repair machinery.

Security protocol for online banking and Facebook has 'serious weaknesses,' say researchers
The protocol that provides security for online banking, credit card data and Facebook has major weaknesses, according to researchers at Royal Holloway University.

Prescription overdose rate reaches epidemic levels in NYC
The rate of drug overdose from prescription opioids increased seven-fold in New York City over a 16-year period and was concentrated especially among white residents of the city, according to latest research at Columbia University's Mailman School of Public Health.

Pioneering research helps to unravel the brain's vision secrets
A new study led by scientists at the Universities of York and Bradford has identified the two areas of the brain responsible for our perception of orientation and shape.

Climate change clues from tiny marine algae -- ancient and modern
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago.
