Cell phone users beware: Talking and listening impairs your ability to drive safely
New research shows that people have greater difficultly maintaining a fixed speed, or keeping their car safe in a single lane when performing tasks that simulated conversing on a mobile phone, than if they were driving without the distraction.

New images reveal different magma pools form the ocean's crust
For the first time, scientists have produced images of the oceanic crust and found that the upper and lower layers of the crust are likely formed from different magma pools.

Race and sex disparities in heart attack care, survival not improving
Differences based on race and sex in treatment patterns for hospitalized American heart attack patients have remained unchanged over an eight-year period, despite improvements in quality of heart attack care during this time, Emory and Yale School of Medicine researchers write in the August 18 issue of New England Journal of Medicine.

Ways to avoid hazards of heart bypass under study
The heart-lung bypass machine that stills the heart while surgeons bypass an adult's clogged arteries or repair a baby's malformed heart can also trigger a potentially deadly inflammatory response.

Improving the potential of cancer vaccines
A special stretch of genetic material may turn off the immune suppression that stymies attempts to fight cancer with a vaccine, said researchers at Baylor College of Medicine (BCM) at Houston.

Researchers seek to discover what really happens when a virus enters the body
Does the immune system respond to viruses because they are foreign or when they cause harm?

New defibrillator signals doctor of patient's irregular heartbeat or device malfunction
In a major advance for heart patients, Loyola University Health System is the first hospital in the U.S. to implant into a patient a new FDA-approved defibrillator which automatically signals the doctor via wireless satellite transmission if the patient's heart beats abnormally or if the device malfunctions, e.g., battery failure.

K-State eye researchers focus on stopping spread of damaged eye cells
A team of four eye researchers at Kansas State University is examining how cells communicate.

Novel plague virulence factor identified
Researchers at Duke University Medical Center have identified a previously unknown family of virulence factors that make the bacterium responsible for the plague especially efficient at killing its host.

The team of Prof. Stefan H.E. Kaufmann at the Max Planck Institute for Infection Biology in Berlin has designed a novel tuberculosis vaccine with high vaccine efficacy.

Species evolve to the brink of evolution
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics.

Fewer wrinkles and firmer skin linked to earlier use of estrogen therapy
Long-term hormone therapy used earlier in menopause is associated with fewer wrinkles and less skin rigidity in postmenopausal women, Yale School of Medicine researchers report in the August issue of Fertility and Sterility.
