Crystal meth users were also significantly more likely to use other drugs, the results showed. Most (85%) of the 396 samples positive for crystal meth also tested positive for at least...

Tests for 'face-blindness' reveal disorder may not be so rare

The neurological basis of the disorder remains poorly understood, although research has confirmed that the brain processes fac...

Study shows interruption of antiretroviral therapy increases risk of disease and death

... the largest HIV/AIDS therapy studies conducted to date show that a specific strategy of interrupting antiretroviral therapy more than doubles the risk of AIDS or death from any cause. Researchers affiliated with the Mailman School of Public Health and Harlem Hospital Hospital led a large multi-center int...

High HPV concentrations combined with smoking significantly raise risks of cervical cancer

...cancer-free women in one of the largest studies to date to examine the relationships between smoking and the human papilloma virus (HPV). The virus and smoking behavior have long been associated with the disease, but not enough evidence has come forth to determine how either may cause the disease. Gunn...

Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals

In the most thorough study to date of the Neanderthal genome, scientists suggest an early human-Neanderthal split. The two species have a common ancestry, say the authors, but do not share much else after evolving their separate ways. The study, published in this week's issue of Scien...

Working on extracts of stalagmite deposits from immediately above and below the body, they dated the skeleton at around 2.2 million years old. Their findings, published in the American journal Science, are controversial. Earlier estim...

Two studies on bee evolution reveal surprises
