Starting antiretroviral treatment early improves outcomes for HIV-infected individuals
A major international randomized clinical trial has found that HIV-infected individuals have a considerably lower risk of developing AIDS or other serious illnesses if they start taking antiretroviral drugs sooner, when their CD4+ T-cell count—a key measure of immune system health—is higher, instead of waiting until the CD4+ cell count drops to lower levels. Together with data from previous studies showing that antiretroviral treatment reduced the risk of HIV transmission to uninfected sexual partners, these findings support offering treatment to everyone with HIV.

Study reveals novel use of 3-D imaging for measurement of injectable wrinkle reducers
A three-dimensional imaging technique often used in the automotive and aerospace industries for accurate measurement may be useful to measure the efficacy of injectable wrinkle reducers such as Botox and Dysport, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The procedure, called three-dimensional speckle tracking photogrammetry, is described in the May issue of Plastic and Reconstructive Surgery. Authors say it has the potential to measure the efficacy of several treatments for which these types of injections are used, not only for cosmetic purposes but also to reduce facial paralysis arising from stroke and Bell's palsy.

Study tackles evolution mystery of animal, plant warning cues for survival
Not every encounter between predator and prey results in death. A new study co-authored by a University of Tennessee, Knoxville, professor suggests that prey emit warning cues that can ultimately lead to both their survival and that of their predators. The hypothesis addresses a 150-year-old mystery of evolution on how warning signals of animals and plants arise and explains animals' instinctive avoidances of dangerous prey.

Importance of clinically actionable results in genetic panel testing for cancer
While advances in technology have made multigene testing, or 'panel testing,' for genetic mutations that increase the risk of breast or other cancers an option, authors of a review say larger studies are needed in order to provide reliable risk estimates for counseling these patients.
