New study shows drivers using cell phones twice as likely to cause rear-end collisions
Drivers talking on cell phones are nearly twice as likely as other drivers involved in crashes to have rear-end collisions, according to a new University of North Carolina at Chapel Hill study.

Mothers' psychological symptoms influence which children go to the doctor
Children whose mothers are the most depressed, anxious, and report high levels of psychosomatic symptom are twice as likely to be taken to a doctor when they complain of a stomach ache or abdominal pain than are children whose mothers report the least amount of such mental stress.

The National Institute on Drug Abuse is hosting a symposium,

Economist says trading life for identity is key to the 'logic' of suicide terrorism
Suicide terrorism seems to many to defy logic. Economists find the idea particularly hard to understand in the context of economic theories that are usually based on ideas of self interest: surely self interest must preclude self killing?

Study finds opioids offer significant reduction in nerve-damage pain
Attempting to resolve a long-standing controversy, UCSF researchers have shown that people suffering from chronic pain due to nervous system damage - known as neuropathic pain -- improved significantly after an eight-week course of the morphine-like medication levorphanol.

Reducing the number of walk-in patients won't help solve emergency department overcrowding: Study
On any given day, hospitals divert ambulances as much as 40 per cent of the time due to overcrowding in their emergency departments - but reducing the volume of walk-in patients with minor illnesses will not alleviate the problem, says a new study by University of Toronto researchers.

New proteomic techniques reveal workings of bacteria linked to cystic fibrosis
Researchers have identified a cell signaling system that may help the bacterium Pseudomonas aeruginosa establish itself in the lungs of cystic fibrosis patients.
