News Scan Briefs: Eyes on the Tops of Their Heads; Play Dates for Germ Sharing; Another Gene for Alzheimer's
Jeudi 11 Septembre 2008 - 22:00 - 2 mois, 2 semaines depuis - Presse spécialisée - Scientific American
Not So Rapid Eye MovementThe bizarre metamorphosis that occurs in halibut and other flatfish had even Charles Darwin floundering for an explanation. At birth, these fish have one eye on each side of the skull, but as adults, both eyes reside on the same side. Certainly, for fish that spend their lives along the sea bottom, having both eyes topside confers a survival advantage. But there seemed to be no evolutionary reason to start down the gradual path toward such lopsidedness--any intermediate steps would not seem to be especially helpful. So some biologists theorized that the fish evolved from a single, sudden mutation. [More]

From Wine to New Drugs: A Novel Way to Reduce Damage from Heart Attacks
Jeudi 11 Septembre 2008 - 16:30 - 2 mois, 2 semaines depuis - Presse spécialisée - Scientific American
An alcohol-busting enzyme may help prevent heart attack damage, according to a new study in Science.

Pass It On: Children Can Inherit Herpes via Parental DNA
Mercredi 10 Septembre 2008 - 14:30 - 2 mois, 3 semaines depuis - Presse spécialisée - Scientific American
A chip off the old block, a kid inherits a multitude of his or her parents' traits, such as eye and hair color. But new evidence suggests that parents may also pass on a common virus to their offspring hereditarily. Researchers estimate that one of every 116 newborns may have human herpesvirus 6 (HHV-6) infections that originated when the virus inserted its genetic material into that of their parents' DNA.HHV-6 is the virus responsible for roseola--a mild childhood infection resulting in high fevers and occasionally associated with a rash. In rare cases the infection is accompanied by seizures as well as respiratory and gastrointestinal complications. By age three, nearly all children have acquired the virus, most likely passed through the saliva of caretakers or other kids. [More]

What is histoplasmosis?
Vendredi 05 Septembre 2008 - 16:30 - 2 mois, 3 semaines depuis - Presse spécialisée - Scientific American
Fungal infections are common and usually treatable. But they can be deadly in patients with immune systems compromised by diseases such as AIDS or by meds taken to keep them in check when they become too active (causing so-called autoimmune conditions such as lupus and rheumatoid arthritis), or to prevent rejection of organ transplants.

Researchers Pinpoint Genes Linked to Childhood Inflammatory Bowel Disease
Vendredi 05 Septembre 2008 - 10:00 - 2 mois, 3 semaines depuis - Presse spécialisée - Scientific American
Researchers have identified a pair of genes that increase a child's risk of developing inflammatory bowel disease (IBD) before the age of 19--adding to a growing list of 30 known genetic factors for the malady.Inflammatory bowel disease is a chronic condition that affects an estimated 1.4 million people in the U.S., according to the Centers for Disease Control and Prevention (CDC) . Abnormal immune responses lead to inflammation in the digestive tract lining causing several disorders, the most common of which are Crohn's disease (usually affecting the small intestine) and ulcerative colitis (restricted to the colon).
