PET Outperforms CT In Characterization Of Lung Nodules, Study Shows
Researchers involved in a large, multi-institutional study comparing the accuracy of positron emission tomography and computed tomography in the characterization of lung nodules found that PET was far more reliable in detecting whether or not a nodule was malignant.

Giving Mice A Cold Virus Offers Hope Of New Asthma Treatments
Scientists have been able to recreate rhinovirus infection, which is behind most common colds, in a small animal for the first time. For fifty years since they were discovered, it had been thought that rhinoviruses could only infect humans and chimpanzees. Rhinoviruses are an unwelcome inconvenience for the majority of the population as they cause around three quarters of common colds.

Study Examines Lifestyle Factors and Ovarian Cancer
Are smokers and coffee drinkers at a greater risk for ovarian cancer? Harvard Medical School researchers looked for links. Their results, published this week in Cancer, come with caveats.

Birth Control Pill Use Cuts Ovarian Cancer Risk
A new study from The Lancet finds that the longer a woman takes birth control pills, the lower her risk of ovarian cancer.

Antiretroviral Drugs May Protect Against Sexual Transmission Of HIV
A new study in macaques suggests that antiretroviral drugs used to treat HIV could also protect people from getting the AIDS virus, especially if two drugs are taken in combination before exposure to the virus occurs. The study found that macaques which were repeatedly exposed to SHIV (a virus closely related to HIV) but received antiretroviral drugs were less likely to become infected than exposed macaques that received no anti-HIV medication. The best protection was seen in macaques that had received a combination of two drugs.
