Genetic mutations affecting a single gene called LRRK2 play an outsized role in Parkinson's disease, but nobody's been able to say what the connection is between the genetic defect and the brain-cell die-off that characterizes the condition. Here's a clue.

Stanford researchers have shown in rats that pharmacologically active amounts of a fast-acting anesthetic drug could be released from nanoparticle "cages" in small, specified brain areas at which the scientists had aimed a beam of focused ultrasound. In principle, the same approach could work for many drugs with widely differing pharmacological actions and psychiatric applications, and even for some chemotherapeutic drugs used to combat cancer.

Much of what we know about the immune system comes from experiments conducted on mice.  But lab mice are not little human beings. The two species are separated by both physiology and  lifestyles. Stanford immunologist Mark Davis is calling on his colleagues to shift their research focus to people.

Antiretroviral therapy, a breakthrough treatment for HIV infection, suppresses the levels of circulating HIV viral particles in the blood. When it works, cancer rates drop, according to a new study. Still, even when the therapy is successful, HIV-positive individuals retain elevated rates of cancer.
