New Evidence On Why Alcohol Consumption Is A Risk Factor For Cancer Why is alcohol consumption a risk factor for cancers of the oral cavity, pharynx, larynx, and esophagus? Scientists long have suspected that the culprit is acetaldehyde, a compound produced as the body breaks down the alcohol in beer, wine and hard liquor. New Test For Early Detection Of Prostate Cancer Shows Promise In the first clinical study of a new blood protein associated with prostate cancer, researchers have found that the marker, called EPCA or early prostate cancer antigen, can successfully detect prostate cancer in its earliest stages. At the same time, the marker successfully avoids the problem of false positive results that plagues prostate-specific antigen (PSA) testing. Reading Ability Protects Brain From Lead Exposure Lead smelter workers who are better readers have more protection against the effect of lead exposure on the brain than those who do not read as well, according to a study on the impact of cognitive reserve. Experiencing Auras? You May Be A Good Candidate For Epilepsy Surgery People with epilepsy who experience multiple auras, sensations such as a cold breeze or bright light before they have a seizure, may be good candidates for epilepsy surgery because their seizures seem to be coming from one area of the brain, according to a new study. Early School Success Protects Against Teen And Young Adult Drug Use Adolescents who do well in school are less likely to smoke, drink or do drugs. But which comes first: drug use or school failure? Patterns of educational success or failure are well established for most adolescents by the time they reach the end of eighth grade, while drug use has only begun to emerge by that time. Nanotube Adhesive Sticks Better Than A Gecko's Foot Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers have now taken one sticky step in the right direction, creating synthetic "gecko tape"with four times the sticking power of the real thing. Discovery Could Help In The Development Of Sensors Against Chemical Th Single-walled carbon nanotubes (SWNTs), which could play an important role in developing sensors against chemical threats, have enhanced interaction with ammonia because of the presence of oxygen groups on the nanotubes, researchers at Temple University have discovered. Spring In Your Step Helps Avert Disastrous Stumbles, Scientists Say From graceful ballerinas to clumsy-looking birds, everyone occasionally loses their footing. New Harvard University research suggests that it could literally be the spring, or damper, in your step that helps you bounce back from a stumble. NASA's Swift Satellite Finds Newborn Black Holes Scientists using NASA's Swift satellite say they have found newborn black holes, just seconds old, in a confused state of existence. The holes are consuming material falling into them while somehow propelling other material away at great speeds. Genetics Has Key Role In Obesity A new line of evidence ties the risk of obesity to genetics. The modern Pima Indians have an unusually high rate of obesity but the new findings could be extrapolated to other populations.
