Virtual liver model could help reduce overdose risk from acetaminophen, other drugs Researchers at Indiana University's Biocomplexity Institute have developed a virtual model of the human liver to better understand how the organ metabolizes acetaminophen (paracetamol), a common non-prescription painkiller and fever-reducer used in over-the-counter drugs such as Tylenol. Extreme tornado outbreaks are becoming more extreme Outbreaks of tornadoes—where multiple tornadoes form over an area in just a few hours or days—are responsible for most of the devastating destruction caused by severe weather, and a new analysis has reached a worrying conclusion about the worst of these outbreaks.
