Ten miniature models of various human organs have been connected together to create the closest we've come yet to a human-on-a-chip. The system survived for four weeks, and allowed scientists to test the effects of a common painkiller on multiple organs. Such systems could eventually do away with animal testing, says Linda Griffith at the Massachusetts Institute of Technology, who led the work. Scientists around the world have been developing organs-on-chips.
Two people were injured Friday afternoon when a helicopter crashed near the helipad on top of Keck Hospital of USC, fire officials said. Officials have not determined who the injured occupants are or the extent of their injuries, according to the Los Angeles Fire Department. The aircraft that crashed was a private ambulance helicopter that was transporting a donated organ to the hospital. It was last reported to be on its side with no fire, said LAFD spokeswoman Margaret Stewart. "The aircraft is stable on its side, on the helipad," LAFD said in a news alert.
