On monday in Washington, President Obama heralded the return of what he terms "sound science" to the administration of federal policy. At that moment in Los Angeles, a joint federal and local law enforcement task force was investigating the latest incident in a 3-year-old terrorist campaign being waged against UCLA medical researchers.

On the cusp of a new era in stem cell science, Democratic heavyweights are pushing to install the outgoing California Democratic Party chief in a leadership post at the state's $3-billion research program. Art Torres, who served two decades as a state lawmaker before assuming the party chairmanship a dozen years ago, is being backed by House Speaker Nancy Pelosi, U.S. Sens. Dianne Feinstein and Barbara Boxer of California and Sen. Ted Kennedy of Massachusetts, among others.

Patients with advanced Parkinson's disease who received deep brain stimulation showed greater improvement in movement and quality of life after six months than those treated with medication, a new study shows. But the deep brain stimulation patients had an almost four times greater risk of serious side effects such as depression, infections, falls or heart problems. Although most side effects could be treated, one patient suffered a brain hemorrhage and died.

An experimental drug protected mice exposed to tobacco smoke from developing chronic lung disease, raising hope for a treatment in humans, U.S. researchers reported Tuesday in the Proceedings of the National Academy of Sciences. CDDO-Im helped activate a gene called Nrf2 that bolsters the lung's ability to fight off chronic obstructive pulmonary disease, a condition that includes emphysema, chronic bronchitis and some types of asthma. Researchers exposed mice to cigarette smoke for six months to simulate the lung damage seen in emphysema.

Instead of infiltrating breaks in the skin, HIV appears to attack normal, healthy genital tissue in women, researchers have found. It had been thought that HIV sought breaks in the skin, such as a herpes sore, to gain access to immune-system cells deeper in the tissue. The findings were presented this week at a meeting of the American Society for Cell Biology in San Francisco.

Heart transplant patients are as much as 25% more likely to survive if the sex of the donor is the same as the patient's, researchers said Wednesday. The results surprised experts because, for most types of transplants, sex differences are irrelevant as long as a good immunocompatability is achieved.

A British plan to allow scientists to use hybrid animal-human embryos for stem cell research won final approval from lawmakers in a sweeping overhaul of sensitive science laws. The House of Commons also clarified laws that allow the screening of embryos to produce babies with suitable bone marrow or other material for transplant to sick siblings. The legislators voted 355 to 129 to authorize the proposals after months of debate that has pitted Prime Minister Gordon Brown's government and scientists against religious leaders, antiabortion campaigners and others.

Using a fan to circulate air seemed to lower the risk of sudden infant death syndrome in a study of nearly 500 babies, researchers reported Monday. Researchers found that fan use was associated with a 72% lower risk of SIDS, according to the study published in October's Archives of Pediatrics & Adolescent Medicine. Placing babies on their backs to sleep is the best advice for preventing SIDS, a still-mysterious cause of death. Experts also recommend a firm mattress, removing toys and pillows from cribs, and keeping infants from getting too warm.
