Enzyme's Cancer-promoting Activities Linked To Inactivation Of 'Genome
The enzyme WIP1 becomes cancer-causing when there is too much of it, preventing the p53 gene from protecting the genome against dangerous DNA mutations, according to new research. The gene p53 prevents a damaged or stressed cell from dividing. When these damaged cells cannot reproduce, they cannot repeat the genetic changes that have led to their damage. America's Farm Bill 2007
Material from the U.S. Department of Agriculture (USDA) about the 2007 reauthorization of the Farm Bill, which provides subsidies to U.S. farmers. The 2007 bill includes "more than 65 proposals [that] correspond to the 2002 farm bill titles with additional special focus areas, including specialty crops, beginning farmers and ranchers, and socially disadvantaged producers."Includes news, fact sheets, and related material on topics such as conservation, energy, forestry, nutrition, and rural development. Gene Therapy For Parkinson's Hitches Ride On Virus
A new clinical trial is examining whether therapeutic genes that hitch a ride with a harmless virus attracted to nerve cells can reduce Parkinson's disease symptoms. The year-long trial involves pairing an inactive virus known as AAV2 with a gene that causes nerve cells to produce neurturin, a protein that may improve the function of dopamine-producing cells and protect them against damage. Landmark Addiction Study Finds People Underestimate Power Of Drug Crav
A novel experiment conducted by Carnegie Mellon University Professor George Loewenstein and colleagues may explain why people try a drug, such as heroin, for the first time despite ample evidence that it is addictive. The results of the study, which are being published in the Journal of Health Economics, reveal that even longtime addicts underestimate the influence that drug cravings have over their behavior. Proteins As Parents: Recombining Parts Yields New Mechanical Propertie
A team from the University of British Columbia succeeded in producing proteins with new mechanical properties through the combination of two "parent"protein fragments. Water of Life, Water of Death
Article about "'water intoxication' or hyponatremia [which] occurs when there is little or no sodium in the blood stream. This usually happens because sodium is lost in sweat during high intensity exercises (such as marathons)."This condition, which may lead to death, also has occurred during hazing incidents. Includes symptoms and tips to prevent water intoxication. From Mothers Against School Hazing (MASH). .. LII Tip of the Week: LII Site Migration Countdown
Reminder: we're getting ready to push off from the old LII system and migrate to the new system. We're not exactly sure what the magic day will be, except that it will be before September 30. Our main URL will continue to be http://lii.org and we will redirect as many queries and pages as possible. Anyone interested in a peek at the new system is welcome to email us at lii@lii.org. Fossils Older Than Dinosaurs Reveal Pattern Of Early Animal Evolution
The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago. Charting The Path Of The Deadly Ebola Virus In Central Africa
Over the past ten years, separate outbreaks of the deadly Zaire strain of Ebola virus (ZEBOV) have killed hundreds of humans and tens of thousands of great apes in Gabon and the Republic of Congo -- which harbor roughly 80% of the last remaining wild gorilla and chimpanzee populations. In a new study, Peter Walsh, Roman Biek, and Leslie Real combined genetic data with information on the timing and location of past ZEBOV outbreaks to support the hypothesis that a "consistently moving wave of ZEBOV infection"recently spread to outbreak sites in Gabon and Congo. Taking A Bite Out Of The Problem: Researchers Devise Dinosaur Classifi
Josh Smith, PhD, assistant professor of earth and planetary sciences at Washington University in St. Louis, has concocted a mathematical scheme for identifying dinosaurs based upon measurements of their copious Mesozoic dental droppings. His method could help paleobiologists identify and reconstruct the lives of the creatures that roamed our terra firma many millions of years ago.
