For years, doctors treating those with HIV have recognized a relationship between how faithfully patients take the drugs they prescribe, and how likely the virus is to develop drug resistance. New research is helping to explain why those differences exist, and may help doctors quickly and cheaply design new combinations of drugs that are less likely to result in resistance.

DEAD-box proteins, which are ancient enzymes found in all forms of life, function as recycling "nanopistons." They use chemical energy to clamp down and pry open RNA strands, thereby enabling the formation of new structures.

Pooling data from thousands of tests of the antiviral activity of more than 20 commonly used anti-HIV drugs, AIDS experts have developed what they say is the first accurate computer simulation to explain drug effects. Already, the model clarifies how and why some treatment regimens fail in some patients who lack evidence of drug resistance.

Scientists have restored the sense of smell in mice through gene therapy for the first time -- a hopeful sign for people who can’t smell anything from birth or lose it due to disease. The achievement in curing congenital anosmia may also aid research on other conditions that also stem from problems with the cilia.

Men and women who undergo joint replacement procedures, as well as those who have significant fractures, tend to be at an increased risk of developing pulmonary emboli (PE), blood clots that travel to the lungs where they may cause serious complications and even death. Patients are often aggressively treated with anticoagulants, or blood thinners, to help prevent the clots from forming, but a new study indicates that some blood clots being identified by today's sensitive testing methods may not require aggressive treatments.
