What is Deep Vein Thrombosis (DVT)?
Jeudi 18 Septembre 2008 - 15:30 - 2 mois depuis - 3 lectures - Presse spécialisée - Scientific American
Acting Surgeon General Steven Galson issued a "call to action" this week to make more Americans aware of Deep Vein Thrombosis, life-threatening blood clots that occur in the legs or pelvis. The condition affects 350,000 to 600,000 Americans every year. DVT and pulmonary embolism (lung blood clots; some originate in the legs) kill an estimated 100,000 people annually, according to Galson. [More]

Rethinking the Wrinkling: Key Genes Cause Aging
Mercredi 17 Septembre 2008 - 22:00 - 2 mois depuis - 3 lectures - Presse spécialisée - Scientific American
It afflicts every creature on this planet, and everyone dreams of an antidote. But even after decades of research, aging largely remains a mystery. Now new research findings suggest there is a good reason for this impasse: scientists may have been thinking about the causes of aging all wrong. Instead of being the result of an accumulation of genetic and cellular damage, new evidence suggests that aging may occur when genetic programs for development go awry.The idea that stress and reactive forms of oxygen--“free radicals” that are the normal by-products of metabolism--cause aging has dominated the field for 50 years. Studies on the worm Caenorhabditis elegans have shown that reducing exposure to reactive oxygen species increases life span, and worms that have been bred to live longer are also more resistant to stress. But few studies have definitively linked oxidative damage to altered cellular function. [More]

Seedy but Speedy: Fungus Spews Spores at 55 Mph
Mercredi 17 Septembre 2008 - 17:55 - 2 mois depuis - 3 lectures - Presse spécialisée - Scientific American
In a finding that could help control harmful fungus, researchers have discovered a high-speed mechanism the germs use to project their spores into the air. Scientists from Miami University (M.U.) in Oxford, Ohio, and the College of Mount St. Joseph in Cincinnati report in the journal PLoS ONE that fungi may be one of the fastest land species, clocking speeds of up to 55 miles (88 kilometers) per hour and producing accelerations 180,000 times greater than gravity.

Open-Source Thinking Revolutionizes Prosthetic Limbs
Mardi 16 Septembre 2008 - 22:00 - 2 mois depuis - 3 lectures - Presse spécialisée - Scientific American
Before Jonathan Kuniholm, a marine reservist, was shipped off to the war in Iraq, he and three friends formed a research and development firm they called Tackle Design. The four men had worked together in an industrial engineering class at North Carolina State University (N.C.S.U.), and, filled with youthful enthusiasm, they hoped their fledgling company could survive on jobs that were interesting and beneficial rather than simply moneymaking. They worked with inventors--making prototypes for a plastic lock to keep shoestrings tied and a fishing lure with an embedded LED--as well as with medical engineers from their alma mater, who were developing tools for minimally invasive robotic surgery.Then, before business had a chance to get off the ground, Kuniholm was deployed. A few months later, on New Year’s Day 2005, he and about 35 other marines were ambushed near the Hadithah Dam along the Euphrates River northwest of Baghdad. His platoon had been looking for insurgents who had fired at a Swift boat patrolling around the dam a few hours earlier. As the marines closed in on the suspected hotspot, an IED--improvised explosive device--hidden in a can of olive oil exploded. Shrapnel ripped through the platoon, and Kuniholm was blasted off his feet. Moments later, when he came to his senses, he discovered his M16 rifle had been blown in half and his right arm was nearly severed just below the elbow. Caught in a raging firefight, Kuniholm pulled himself out of harm’s way. His fellow marines called for air evacuation, and soon surgeons at a hospital near Baghdad were amputating his ravaged arm.
