"Save Your Face - Drink Sensibly" - Assault And Alcohol Major Causes Of Facial Injury
Assault and alcohol consumption are the two major factors responsible for serious facial injuries in young adults. One half of the facial injuries in the 15 - 25 year age group were sustained in assaults, usually in bars or streets, and were associated with alcohol consumption. From 1977 to 1987 the proportion of patients with facial injuries sustained in road accidents fell by 34 per cent, but violent crime has more than compensated for this decrease.

Study Shows Active, Passive Smoking Harden Arteries, Increase Stroke Risk
Both active and passive smoking speed up the process by which arteries become clogged and increase the risk of strokes and heart attacks, according to a major new study. The damage -- sometimes likened to rust building up in iron pipes and restricting water flow -- may be irreversible.

Tiger Beetles Go Blind At High Speeds
Entomologists have long noticed that tiger beetles stop-and- go in their pursuit of prey. But up to now, scientists have had no idea why this species of beetle attacks its food in fits and starts. Why do they stop and go? During hot pursuit of prey, the tiger beetles go blind.

Researchers at Columbia University College of Physicians & Surgeons have discovered the first human gene associated with hair loss. The new gene, called hairless, is linked to a severe form of inherited baldness and may be the trigger that turns on the entire human hair cycle. The discovery could lead to a better understanding of the hair cycle and, eventually, more effective treatments for various forms of hair loss.

Transcranial Magnetic Stimulation Enhances Short-Term Brain Plasticity
For the first time, scientists studying how the brain reorganizes itself have shown that they can modify this process using a technique called transcranial magnetic stimulation (TMS). The finding suggests new ways to help people recover normal function after stroke, amputation, and other injuries.

Natural Killer Cells Need A Good Night's Sleep
Disrupted sleep may be weakening the immune systems of elderly widows and widowers. After 29 patients with bereavement-related depression spent three nights in a sleep lab, analysis of blood samples showed those whose sleep had been disrupted had fewer natural killer cells (NKCs), which help destroy illness-causing cells.

National Jewish Researchers Study Value Of Frequent Nurse Visits To Homes Of Low-Income Children At High Risk Of Asthma
