Just because more men pursue careers in science and engineering does not mean they are actually better at math than women are. The difference is that men think they are much better at math than they really are. Women, on the other hand, tend to accurately estimate their arithmetic prowess.
New research could help reverse deadly side effects caused by excessive doses of the drug acetaminophen, the major ingredient in Tylenol and many other medicines. Researchers have developed a mathematical model of acetaminophen metabolism based on data from rats. The findings suggest that giving patients glutamine -- a common amino acid in the body -- alongside the standard antidote for acetaminophen overdose could prevent liver damage and boost the body's ability to recover.
