Rugby Kick Success May Come Down To Swing Of The Arm, Shows Research
The prodigious kicking success of England rugby player Johnny Wilkinson's may come down to what he does with his arms -- but it is not just his trademark preparation stance that does the trick. Locating the Source of the Plame Leak
Collection of news stories (audio files) and background information on the events surrounding the CIA leak case, in which "identity of an undercover CIA operative, Valerie Plame, appeared in the press, with Bush administration officials cited as the source. An ongoing investigation has resulted in the indictment of Lewis Libby, ... chief of staff for Vice President Dick Cheney."Includes a timeline (2002-2005), questions and answers, and legal documents from the case. From National Public Radio (NPR). Sticky Mutant Proteins Implicated In Lou Gehrig's Disease
A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell. Testing For Joint Substance In Blood Might Improve Diagnosis Of Osteoa
Measuring a biological chemical called hyaluronan found naturally in joints and the fluid that lubricates cartilage might enable doctors to diagnose osteoarthritis of the knee and hip earlier or more accurately, a new study concludes. Improving diagnosis of the painful inflammatory disorder should become increasingly important as baby boomer age, doctors say. Telling Axons Where To Go ... And Grow
In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg (Germany) describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons. 'Bad Carbs'Not The Enemy, Professor Finds
The latest common wisdom on carbohydrates claims that eating so-called "bad"carbohydrates will make you fat, but University of Virginia professor Glenn Gaesser says, "that's just nonsense."Eating sandwiches with white bread, or an occasional doughnut, isn't going to kill you, or necessarily even lead to obesity, he said. Non-steroidal Anti-inflammatory Drug Increases Liver Damage In Mice Ca
Research performed at Washington University School of Medicine in St. Louis sheds light on the mechanisms that contribute to liver disease in alpha-1-AT deficiency patients. People with alpha-1-deficiency have a genetic mutation that can lead to emphysema at an early age and to liver damage. Using an experimental mouse model of the disorder, the researchers investigated the effects of a non-steroidal anti-inflammatory drug on liver injury. More Species In The Tropics Because Species Have Been There Longer, St
Why are there more species in the tropics than in the temperate regions of the globe? Many of the world's species live in the tropics (perhaps more than half), but the reason has been debated for more than 100 years. Debunking Constipation Myths: The Truth About High Fiber Diets And Lax
There are a lot of common myths about constipation treatment. An article in the January issue of The American Journal of Gastroenterology dispels those myths and clears numerous misconceptions regarding chronic constipation. From a high fiber diet to taking laxatives, researchers address the common beliefs concerning various aspects of the condition and review results based on medical trials. Bone Marrow Fat May Indicate Bone Weakening
Measuring bone marrow fat (BMF) along with bone mineral density (BMD) can better predict weakening of bones than either test done alone, a new study indicates. BMD measurement with DEXA is presently the most commonly used parameter for determining bone weakening. Researchers have long questioned whether there may be other measurable bone components that influence mechanical stability of bone.
