As more people rise to the challenge of rock climbing for fun and exercise, the number of injuries related to the sport also increases, according to the first national study on the subject.
More than 40,000 people sought treatment in U.S. emergency rooms from 1990 to 2007 for fractures, sprains and other ailments related to rock-climbing -- a 63 percent increase during that time.

A new survey by the Emergency Nurses Association suggests that more than one-half of emergency department (ED) nurses experience physical violence in the workplace. The report, which was based on an online survey conducted in spring 2007 of 3,465 ED nurses nationwide, also finds that one in four ED nurses reports being physically assaulted while on the job more than 20 times during the past three years. In addition, the report finds that one in five ED nurses reports having been verbally abused in the workplace more than 200 times during the last three years.
Placebos are a sham - usually mere sugar pills designed to represent "no treatment" in a clinical treatment study.

How well placebos work varies widely among individuals. Why that is so, and why they work at all, remains a mystery, thought to be based on some combination of biological and psychological factors.
