The likelihood of three genetic variants being associated with a risk of Crohn disease is lower than many previous studies indicated, states a research article (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj090684.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca.

Last year, researchers made a game-changing realization: brown fat, the energy-burning stuff that keeps babies warm, isn't just for the youngest among us. Adults have it, too (if they are lucky, anyway), and it is beginning to look like the heat-generating tissue might hold considerable metabolic importance for familiar and irritating trends, like our tendency to put on extra weight as we age.
DURHAM, N.C. – A new study reconstructing thousands of years of fire history in the southern Appalachians supports the use of prescribed fire, or controlled burns, as a tool to reduce the risk of wildfires, restore and maintain forest health and protect rare ecological communities in the region's forests.
CHICAGO (April 6, 2010) – For some, the phrase "spring is in the air" is quite literal. When the winter snow melts and flowers bloom, pollen and other materials can wreak havoc on those suffering from seasonal allergies, usually causing a habit called "mouth breathing." The physical, medical and social problems associated with mouth breathing are not recognized by most health care professionals, according to a study published in the January/February 2010 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD).
DURHAM, N.C. – The number of sea turtles inadvertently snared by commercial fishing gear over the past 20 years may reach into the millions, according to the first peer-reviewed study to compile sea turtle bycatch data from gillnet, trawl and longline fisheries worldwide.
Using CT scans to measure blood flow in the lungs of people who smoke may offer a way to identify which smokers are most at risk of emphysema before the disease damages and eventually destroys areas of the lungs, according to a University of Iowa study.
The study found that smokers who have very subtle signs of emphysema, but still have normal lung function, have very different blood flow patterns in their lungs compared to non-smokers and smokers without signs of emphysema.
Luminescent markers are an indispensable tool for researchers working with DNA. But the markers are troublesome. Some tend to destroy the function and structure of DNA when inserted. Others emit so little light, that they can barely be detected in the hereditary material. So researchers have been asking for alternative markers.
Now a PhD student at the University of Copenhagen has developed a tool in collaboration with researchers at Chalmers Technical University, which might save both problems: A tool that you might call a molecular gauge.
Jerusalem, April 6, 2010 -- Spectacularly increased yields and improved taste have been achieved with hybrid tomato plants by researchers at the Robert H. Smith Faculty of Agriculture, Food and Environment at the Hebrew University and the Cold Spring Harbor Laboratory (CSHL), New York.
An international team led by researchers from the University of Cordoba (UCO) has analysed seroprevalence (antibodies to a disease) of Toxoplasma Gondii, the parasite that causes toxoplasmosis in many species, including humans. This latest study reveals that the parasite is widespread in areas where the wild Iberian Lynx (Lynx pardinus) lives, and also in captive breeding centres. Scientists are now undertaking further research into the disease itself.
Philadelphia, PA, April 5, 2010 – The presence of metallic foreign bodies in the eye is an uncommon injury in children, so much so that two children with autism presenting with this injury led to detective work by two physicians that found the common cause.
Park Ridge, Ill. (April 6, 2010) – A new study demonstrates that eating protein-rich eggs for breakfast reduces hunger and decreases calorie consumption at lunch and throughout the day.
Darwin's finches – some 14 related species of songbirds found on the Galapagos and Cocos Islands – will forever be enshrined in history for having planted the seeds of the theory of evolution through natural selection. Today, exactly 150 years after Darwin's famous book, finches can still teach us a lesson about evolution. A large, international group of researchers, among them Prof. Doron Lancet and Dr. Tsviya Olender of the Weizmann Institute's Molecular Genetics Department, recently produced the full genome of the zebra finch and analyzed it in detail.
A mobile compression device is as effective as medication at preventing the formation of blood clots after hip replacement surgery but provides greater patient safety, according to a study in the March issue of the Journal of Bone & Joint Surgery.
Led by Professors Peter Krustrup and Jens Bangsbo from the Department of Exercise and Sports Sciences, University of Copenhagen, the 3-year project covered several intervention studies involving both men, women and children, who were divided into soccer, running and control groups. The results from the studies are so remarkable that the Scandinavian Journal of Medicine and Science in Sports are publishing a special edition issue entitled "Football for Health" containing 14 scientific articles from the soccer project on Tuesday 6 April 2010.
Soccer for Health
GALVESTON, Texas — Obesity can be detected in infants as young as 6 months, according to a new study by researchers at the University of Texas Medical Branch at Galveston.
