Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life. […]
A doctoral student who discovered a new species of bee in Toronto has completed a study of 84 species of sweat bees in Canada. Nineteen of these species are new to science -- never before identified -- including the new Toronto bee, which is actually quite common in eastern Canada and the US. The new research will help scientists track bee diversity, and und […]
Uninsured minority pedestrians hit by cars are at a significantly higher risk of death than their insured white counterparts, even if the injuries sustained are similar, new research suggests. […]
Iron deficiency is a relatively common nutritional disorder that affects more than one third of the general population, and is often associated with chronic diseases such as inflammatory bowel disease, Parkinson's disease, rheumatoid diseases and renal failure.
