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.

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.

Pfizer Inc. is shifting its drug research focus to diseases that have high potential for big profits and for treatment improvements in such fields as cancer and Alzheimer's disease. The world's biggest drug maker also is ending new research on conditions including obesity and heart disease, but research on drugs already in late-stage human testing will continue, spokeswoman Liz Power said Tuesday.

Even viruses can suffer a viral infection, French scientists reported Thursday in the journal Nature in a discovery that may help explain how viruses swap genes and evolve so rapidly. A new strain of giant virus was isolated from a cooling tower in Paris and found to be infected by a smaller type of virus, named Sputnik, after the first man-made satellite. Sputnik is the first example of a virus infecting another virus to make it sick. The finding may shed light on how viruses mutate so quickly, a feature that can make them difficult to tackle with drugs and vaccines.
