Not Old Enough to Know Better

1 Chronic Cocaine Use Causes "Old Age” Brain

Researchers at the University of Cambridge have found that the brains of chronic, dependent cocaine users show signs of premature aging compared to non-users, with the brains of the former decreasing in volume by approximately 3.08 milliliters of gray matter per year, nearly twice the decline of 1.69 milliliters observed in the brains of the control group. The loss of brain tissue was most advanced in those areas of the brain that are associated with decision making, self-control, memory and attention span: the temporal and prefrontal cortex. The new findings correlate and reinforce previous studies which determined that middle-aged chronic coke users suffered from cognitive decline and cerebral atrophy, signs of mental deterioration usually seen in old age.

Harness Being Investigated

2 Actor Dies After Hanging Himself on Stage

Brazilian actor, Tiago Klimeck, died after accidentally hanging himself while performing in the play “The Passion of the Christ.” Klimeck, 27, spent more than two weeks in a medically-induced coma due to extensive brain injuries from a prolonged lack of oxygen. Klimeck played Judas Iscariot who committed suicide as told in the book of Matthew in the New Testament and wore a harness under his robe during the scene that facilitated his ability to perform without harm. Klimeck hung for four minutes before cast members realized that something was wrong and came to his aid. The harness, and the rope used in the play, are being analyzed at the Criminal Institute of Sorocaba. Klimeck had performed this role for the past three years as part of an annual Good Friday production in Itarare, Brazil.

Disease Not Spread by Milk

3 Mad Cow Disease Found in California Dairy Cow

Mad cow disease was discovered in a dairy cow in the Central Valley in California. The animal was never intended for human consumption. Los Angeles Times reports that while the cow was found at a rendering facility, infected meat never entered the food chain. Federal regulators say that the food supply isn't threatened. John Clifford, the USDA’s chief veterinarian, also stresses that the milk supply is safe. The infected cow was identified through routine testing for bovine spongiform encephalopathy (BSE). According to the World Health Organization, BSE can't be spread through milk. Since 2003, mad cow disease, officially named variant Creutzfeldt-Jakob disease, has been found four times in U.S. cattle.

Women Down by 12

4 Men More Likely to Exercise 30 Minutes Daily

Men are more likely than women to exercise for at least 30 minutes a day, finds a new study. According to research findings, on average, women exercised 18 minutes daily, and men completed 30 minutes of exercise daily. The exercises for both men and women were described as moderate-to-vigorous. Study participants wore an accelerometer, which kept track of movement. MSNBC reports that people in the study who didn't exercise for at least 30 minutes a day were at increased risk for metabolic syndrome, a collection of symptoms that are linked with cardiovascular disease. Symptoms of metabolic syndrome include high blood pressure, low levels of good cholesterol and high blood sugar. The research is published in Preventive Medicine.
