Groundbreaking study on complex movements of enzymes
A groundbreaking study has revealed in great detail how enzymes in the cell cooperate to make fat. These enzymes are integrated into a single molecular complex known as fatty acid synthase. This complex is regarded as a potential target for developing new anti-obesity and anti-cancer drugs. view more (2009-02-12)
News brief: Effects of aspirin and folic acid on inflammation markers for colorectal adenomas
Unexpectedly, inflammation markers do not appear to be involved with the chemopreventative effect of aspirin on colorectal adenomas, according to a brief communication published online October 12 in the Journal of the National Cancer Institute. view more (2009-10-13)
Ida now a coastal low assaulting the Mid-Atlantic
Ida is one stubborn girl. Her remnants have moved out to sea and reformed as a powerful coastal low pressure system that's been raining on the mid-Atlantic since Tuesday night, November 10. view more (2009-11-13)
Fortifying food with folic acid benefits babies
Adding folic acid to food can dramatically reduce the incidence of spina bifida and other birth defects. A study, published today in BMC Pregnancy and Childbirth, shows that the proportion of babies born with neural tube defects in the province of Newfoundland and Labrador dropped by 78% after the Canadian Government directed that folic acid must... view more...

Use of acid-suppressive medications associated with increased risk of hospital-acquired pneumonia
Hospitalized patients who receive acid-suppressive medications such as a proton-pump inhibitor have a 30 percent increased odds of developing pneumonia while in the hospital. view more (2009-05-27)
Adding folic acid to flour significantly reduces congenital malformations
Dr. Philippe De Wals of Université Laval's Department of Social and Preventive Medicine today publishes a study clearly indicating that the addition of folic acid to flours has led to a 46% drop in the incidence of congenital neural tube deformation (mainly anencephaly and spina bifida) in Canada. view more (2007-07-13)
European folic acid policies are not effective enough
The prevalence of neural tube defects in Europe has not declined substantially in the past decade, despite national policies of folic acid supplementation in half the countries, finds a study in this week's BMJ. view more (2005-03-09)
On the volcano island Krakatau: regeneration of rain forest goes hand in hand with genetic diversity
Rain-forest trees colonizing a new piece of land contain a large genetic diversity. The Indonesian island Krakatau is a good natural test case for disrupted tropical rain forest. Here, fig species hybridise unexpectedly. A lesson for the future of nature reserves. Just today, May 13, Tracey Parrish of the Netherlands Institute of Ecology... view more... (2002-05-13)
Gains in the fight against acid aspiration lung injury
Doctors are gaining new leverage in the fight against lung injury caused by acid reflux. The paper by Bonnans et al., "Lipoxin A4 regulates bronchial epithelial cell responses to acid injury," appears in the April issue of The American Journal of Pathology and is accompanied by a commentary. view more (2006-05-03)
Folic acid supplementation does not appear to reduce risk of cardiovascular diseases
An analysis of previous studies suggests that for people with a history of vascular disease, folic acid supplementation does not decrease the risk of coronary heart disease or stroke, as has been suggested in some research. view more (2006-12-13)
Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. view more (2009-10-19)
Rain forest protection works in Peru
A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. view more (2007-08-10)
Acetaminophen or acetylsalicylic acid increases risk of developing chronic kidney failure
People who regularly use high dosages of pain-relievers or antipyretic drugs containing acetaminophen (paracetamol) or acetylsalicylic acid run an increased risk of developing permanent reduced kidney function (chronic renal failure). This was found in a nation-wide Swedish research study published on December 20 in The New England Journal of... view more... (2001-12-21)
Combination treatment enhances tetanus vaccination
In studies with mice, Penn State researchers have shown that a combination of retinoic acid - a product the body makes naturally from vitamin A - and PIC, a synthetic immunity booster, significantly elevates the immune system response to a tetanus shot. view more (2005-09-13)
Desert rhubarb -- a self-irrigating plant
Researchers from the Department of Science Education-Biology at the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert. view more (2009-07-02)
UF geographer: New tools to forecast hurricane rainfall inland
All eyes are on where hurricanes make landfall, but the massive storms actually cause the most deaths inland, where severe flooding often surprises residents. view more (2007-06-20)
Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder. view more (2006-06-21)
Fat overrides effects of vitamin C
Fats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential cancer-forming compounds in the stomach is less... view more...

Studies highlight little known, but potentially serious, manifestations of acid reflux
Many people may not realize that symptoms such as chronic cough or chest pain can be caused by acid reflux into the esophagus, because they do not experience classic heartburn symptoms or acid regurgitation. view more (2007-10-15)
University of Ulster spearheads giant leap forward in medicine
Researchers at the University of Ulster have uncovered a vital weapon in the fight against killer conditions like cancer and heart disease - frog venom. The team, headed by Professor Chris Shaw, has discovered that molecules called peptides, secreted by rain forest frogs to ward off predators, have the potential to: * Dramatically... view more...
