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.

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.

Disheartened by the failures of vaccines and microbicides in blocking HIV transmission, some AIDS researchers are now touting a third possibility: using existing HIV drugs prophylactically. By next year, as many as 15,000 people worldwide will be enrolled in trials to test the concept -- more than are enrolled in all vaccine and microbicide trials combined -- according to a report issued Sunday at the International AIDS Conference in Mexico City. There are seven trials underway or planned.

Federal officials have been underestimating the number of new HIV infections in the United States by 40% every year for more than a decade, a finding that indicates the U.S. epidemic is much worse than thought, researchers said Saturday. Using sophisticated testing to identify new infections, the Centers for Disease Control and Prevention concluded that there are about 56,300 new infections each year, not the 40,000 figure that has been gospel for so long.
