Universal and annual voluntary testing followed by immediate antiretroviral therapy treatment (irrespective of clinical stage or CD4 count) can reduce new HIV cases by 95% within 10 years, according to new findings based on a mathematical model developed by a group of HIV specialists in WHO.
The first trench-to-bench field guide for tracking wild primate infectious diseases provides integrated information that could help scientists identify infection patterns and prevent epidemics.

Scientists may soon give avid golfers another way to improve their game — better balls that fly farther. Up to now, dimple design has been more of an art than a science. For many years, sporting goods companies would design their dimple patterns by simple trial and error, testing prototype after prototype against one another.

Based on the amount and frequency of meteorite falls and the formation of impact craters on the Earth, there should be over 20 impact craters in the <100 m size range that formed within the past 10,000 years, yet only five such craters are known worldwide.
Human degradation of the environment has the potential to stall an ongoing process of planetary evolution, and even rewind the evolutionary clock to leave the planet habitable only by the bacteria that dominated billions of years of Earth’s history, according to Harvard geochemist Charles Langmuir.

Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to an article in PLoS Genetics. Scientists have conducted a genome-wide association study with metabolomics, identifying genetic variants in genes involved in the breakdown of fats. The resulting differences in metabolic capacity can affect individuals’ susceptibility to complex diseases such [...]

If you’re a cancer cell, you want a protein called Bcl-2 on your side because it decides if you live or die. It’s usually a trusted bodyguard, protecting cancer cells from programmed death and allowing them to grow and form tumors. But sometimes it turns into their assassin. Scientists knew it happened, but they didn’t [...]

Scientists have found that blocking the receptor for a specific neuropeptide, short chains of amino acids found in nerve tissue, significantly decreases the desire for nicotine in animal models. In addition, these data may explain intriguing findings from human smokers who spontaneously quit smoking when they suffer brain damage restricted to a small portion of [...]
