It all adds up teens and sex
Too much television, low self-esteem, low grades and poor family relationships can add up to early teenage sex, according to a new study. “If you add up all the factors, you get a much more powerful predictor of who has sex and who doesn’t,” said Dr. Janet Hyde, of the University of Wisconsin, who headed the research team.

Winnipeg lab working on swine flu vaccine
Work on a new vaccine to guard against human swine flu is under way in a Winnipeg lab as health officials across the continent move to contain the growing threat that could spark a worldwide influenza outbreak. With the mysterious disease that initially cropped up in Mexico spreading to Canada, teams of scientists from the Winnipeg-based National Microbiology Lab have started work on a vaccine to protect against H1N1 swine flu and are investigating whether the existing flu shot could offer any protection from the virus.

HIV may be increasing in virulence
These findings agree with those of other researchers, who have reported that patients starting treatment for HIV infection in recent years may have lower CD4+ cell counts at diagnosis and require antiretroviral therapy earlier in the course of disease, Dr. Nancy Crum-Cianflone, from the Naval Medical Center, San Diego, California, and colleagues report.

Fewer than half of U.S. women screened for chlamydia
Fewer than half of vulnerable U.S. women are being screened for chlamydia, a common sexually transmitted disease that often causes few symptoms but can lead to infertility, researchers reported on Thursday. Screening rates have spiked up from 25 percent in 2000 to nearly 42 percent in 2007, but that is still far too few women being screened, the team at the U.S. Centers for Disease Control and Prevention reported.

Breast cancer and ovarian cancer
Cells in general develop and divide simply when they are required to keep our bodies running appropriately. But occasionally, the mechanisms that control cell development end working and cells break up out of control to shape tumors. This is named cancer. When it expands in the cells of breast or ovarian tissue it is called breast or ovarian cancer, respectively. Read more
