Researchers find sex-specific lung cancer genes
Reuters via Medscape Medical News
Lung cancer is often dramatically different in women than it is in men, U.S. researchers reported in another study that suggests ways to tailor treatment for cancer patients. They also found that some elderly patients have forms of lung cancer that make them likely to benefit from chemotherapy, even though the treatments can be harsh.More

Grasping bacterial 'friending' paves the way to disrupt biofilm creation
Medical News Today
Finding a biological mechanism much like an online social network, scientists have identified the bacterial protein VpsT as the master regulator in Vibrio, the cause of cholera and other enteric diseases. This discovery, now published in the journal Science, provides a major tool to combat enteric disease.More

Preeclampsia
Clinical Laboratory News
Preeclampsia is a multisystem disorder of pregnancy characterized by the presence of hypertension and proteinuria after 20 weeks gestation. While estimated to affect only 3 percent–5 percent of all pregnancies in the U.S., the disorder is responsible for 15 percent of premature deliveries and up to 18 percent of maternal deaths.More

Self-cannibalizing cancer cells targeted
Science Daily
A team of scientists from Princeton University and The Cancer Institute of New Jersey has embarked on a major new project to unravel the secret lives of cancer cells that go dormant and self-cannibalize to survive periods of stress. The work may help produce new cancer therapies to stem changes that render cancer cells dangerous and resistant to treatment.More

New decision rule identifies kids with minor head trauma who need CT
Medscape Medical News
A new decision rule can identify children with minor head injury who need to undergo computed tomography, thereby reducing the number of scans and saving children from unnecessary exposure to ionizing radiation, according to a new study published in the Canadian Medical Association Journal.More

Study disputes concerns over plasma from female donors
Los Angeles Times
Three years after the U.S. blood-banking industry recommended against transfusing plasma from female donors because of a potentially life-threatening antibody reaction, researchers have found that plasma from women may actually be better, not worse, for heart surgery patients.More

Stuttering linked to cell waste recycling genes
Reuters
Three genes linked to a rare metabolic disorder may also cause some cases of stuttering, researchers said in a finding that could lead to a new treatment for the speech condition. Two of the genes are used by brain cells as part of a waste recycling process, the researchers reported in the New England Journal of Medicine. A third has no other known role.More

Who owns your cells? New book tackles thorny issue
Reuters
No one cares about the untold numbers of cells our bodies slough off every day. But imagine that someone got hold of your cells — and the DNA they contain — and used them to cure a disease, or somehow managed to make a lot of money off of them. Should you be proud? Could you claim royalties?More
