Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery. That is until now. A group of Dartmouth and UCLA researchers, who normally work on genes…

Polar bears live a feast and famine lifestyle. They are large animals (an adult males weighs 300-600kg) that live in the freezing tundra so they have huge metabolic needs. They normally prey on…

Many studies in coaching literature have found that male athletes tend to prefer a male coach. Newly released research from the University of Alberta has indicated that male athletes actually prefer…

With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the…
