Study confirms gender differences in progression from HIV to AIDS
From the ALIVE cohort, a study of HIV infection and sex differences confirms that women, despite having significantly lower initial plasma viral levels, progress to AIDS just as swiftly as men (NEJM).

How to keep invasive plants out of forest fragments
Fragmented habitat is vulnerable partly because it has more edges, which are susceptible to invasion by non-native species.

Aspirin and other non-specific COX inhibitors may slow atherosclerosis
Mouse-model research by scientists at the University of Pennsylvania School of Medicine has demonstrated that aspirin, ibuprofen and other drugs in the class of pharmaceuticals known as non-specific COX inhibitors may aid substantially in preventing heart disease, slowing the build- up of plaque in blood vessels by more than 50 percent.

MIT pioneers online lab in microelectronics
MIT students can now test and probe fragile, microscopic electronic structures via an online lab that can be accessed from dorm rooms and other convenient locations 24 hours a day.

Girls can internalize negative body images even as pre-adolescents
Dieting among pre-adolescent girls can affect growth and increase risk for low self-esteem, depression and eating disorders.

Study confirms gender differences in progression from HIV to AIDS
One of the largest studies of gender-specific differences of HIV infection found that despite differences in initial viral load, men and women develop AIDS at the same rate.

New infrared and visible-light pictures from the Hubble telescope reveal for the first time important details of large clusters of stars in galaxy M82, which arose from an ancient encounter with its larger neighbor, M81.

Women blame stress for their breast cancer, attribute positive attitude for remission
Most breast cancer survivors attribute a role to stress for causing their disease and believe that a positive attitude has helped them beat it.

New superconducting material packs an applied punch
A team of scientists from the Applied Superconductivity Center at the University of Wisconsin-Madison have discovered that a new high-temperature superconducting metal, magnesium diboride, carries large currents without the common barriers seen in the ceramic superconductors in development for real- world electric power applications.
