Ice Shelf Disintegration Threatens Environment, Queen's Study
The spectacular disintegration of Antarctica's "Larsen-B"Ice Shelf was unprecedented since the last ice age, according to a recent study published in Nature. And the disintegrating Antarctic ice could have huge implications for global warming and rising sea levels. Vanishing Beetle Horns Have Surprise Function
The function of horned beetles' wild protrusions has been a matter of some consternation for biologists. Digging seemed plausible; combat and mate selection, more likely. Even Charles Darwin once weighed in on the matter, suggesting -- one imagines with some frustration -- the horns were merely ornamental. In this month's American Naturalist (Dec. 2006) and the Nov. 2006 issue of Evolution, Indiana University Bloomington scientists present an entirely new function for the horns: during their development, Onthophagus horned beetles use their young horns as a sort of can opener, helping them bust out of thick larval shells. Intel, IBM: Transistor Overhaul
In what experts say is the most dramatic development in transistor tech since the '60s, Intel and IBM separately announce they have figured out how to reduce energy loss in microchip transistors. By the Associated Press. OHSU Discovery Sheds Light Into How Stem Cells Become Brain Cells
Researchers discovered one key gene that appears to control how stem cells become various kinds of brain cells. The scientists wanted to determine if the process can be controlled and used as a possible therapy. What amazed them is a single gene may be responsible for this important task The finding has significant implications for the study of Parkinson's disease, brain and spinal cord injury, and other conditions or diseases. Enhance-athon: Shoot Straighter
Old hat at first-person shooters but new to rifle ranges, Clive Thompson tries to improve his aim. The goal? Ten bull's-eyes in a row. Two Types Of Breast Cancer Treatments Show Similar Benefit
Results from a clinical trial comparing the effectiveness of the drugs paclitaxel and docetaxel, delivered over two different dosing schedules, showed that both drugs -- regardless of the dosing schedules tested in this trial -- provided similar benefits for women with stage II or III, operable breast cancer. However, more women treated with docetaxel than with paclitaxel experienced serious side effects from their treatment. New Drug Abuse Treatment Shows Promise
Patients who receive buprenorphine treatment for opioid addiction in an office--based setting are more likely than those receiving methadone treatment to be young men, new to drug use, and with no history of methadone treatment, Yale School of Medicine researchers report in a study published in Drug and Alcohol Dependence. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Needling Chromosomes Yields Insights Into Cell Division
By impaling individual chromosomes with glass needles one thousandth the diameter of a human hair, a Duke University graduate student has tested their "stickiness"to one another during cell division. Her uncanny surgical skills have added a piece to the large and intricate puzzle of how one cell divides into two -- a process fundamental to all organisms.
