Scientists have an ingenious explanation for the strange ridge belting Saturn's outermost moon, Iapetus For centuries, people wondered how the leopard got its spots. The consensus is pretty solid that evolution played a major role. But it's only been five years since the arrival of high-resolution Cassini Mission images of Saturn's bizarre moon Iapetus that the international planetary community has pondered the unique walnut shape of the large (735 kilometer radius) body, considered by many...

By Diana Lutz , Washington University in St. Louis It sounds a bit like spinning straw into gold, but novel metal catalysts may be able to turn greenhouse gases like methane and carbon dioxide into liquid fuels without producing more carbon waste in the process. If fossil fuels burn completely, the end products are carbon dioxide and water. Today the carbon dioxide is a waste product, one that goes into the air "” adding to global warming; or the oceans "” acidifying them; or...

Discovery may guide treatment for acute myeloid leukemia Decoding the DNA of a woman who died of acute myeloid leukemia (AML) has led researchers at Washington University School of Medicine in St. Louis to a gene that they found to be commonly altered in many patients who died quickly of the disease. The findings, if confirmed in larger studies, suggest that a diagnostic test for mutations in the gene could identify AML patients who need more aggressive treatment right from the start. The new...

By Jim Dryden, Washington University in St. Louis Researchers at Washington University School of Medicine in St. Louis have identified a gene linked to the spread of eye melanoma. Although more research is needed, the researchers say the discovery is an important step in understanding why some tumors spread (metastasize) and others don't. They believe the findings could lead to more effective treatments. Reporting online in the journal Science Express, the team found mutations in a gene...

"You don't have to go out into the woods anymore," says tick expert Brian F. Allan, PhD, who just completed a postdoctoral appointment at Washington University in St. Louis. "The deer are bringing tick-borne disease to us." So, it stands to reason that anything deer like, might increase the risk of tick-borne disease for people. The invasive plant bush honeysuckle, for example. Yes, that leafy shrub with the lovely egg-shaped leaves on arching branches, fragrant white or yellow flowers and...
