The Canadian policy of fortifying grain products with folic acid has already proved to be effective in preventing neural tube defects. view more (2009-05-15)
High-normal uric acid linked with mild cognitive impairment in the elderly
Researchers at the Johns Hopkins and Yale university medical schools have found that a simple blood test to measure uric acid, a measure of kidney function, might reveal a risk factor for cognitive problems in old age. view more (2007-01-02)
Immigrant women may be at higher risk of having a baby with a birth defect
Immigrant women are less likely to use folic acid supplements before pregnancy to prevent spina bifida, particularly those who recently immigrated to the country, according to a new study led by a St. Michael's Hospital physician in collaboration with Statistics Canada, Health Canada and the University of Toronto. view more (2009-04-17)
Ancient mineral shows early Earth climate tough on continents
A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents. view more (2008-06-16)
Cognitive impairment link found in older adults taking popular stomach acid medications
Long-term use of histamine2 receptor antagonists (H2A), one class of drugs that blocks stomach acid, may be associated with cognitive impairment in older African-American adults. view more (2007-08-06)
For fats, longer may not be better
Researchers have uncovered why some dietary fats, specifically long-chain fats, such as oleic acid (found in olive oil), are more prone to induce inflammation. view more (2009-01-09)
Root Beer May Be "Safest" Soft Drink for Teeth
Exposing teeth to soft drinks, even for a short period of time, causes dental erosion—and prolonged exposure can lead to significant enamel loss. Root beer products, however, are non-carbonated and do not contain the acids that harm teeth. view more (2007-03-21)
Antioxidant herbal extract may help prevent and treat reflux oesophagitis
A herbal extract, which contains a powerful antioxidant, may help prevent and treat the extremely common and distressing condition reflux oesophagitis, shows research in Gut. Free radical damage to the lining of the oesophagus or gullet is probably more important than contact with stomach acid in the development of the condition, the study... view more... (2001-08-14)
NASA Looks at Hurricane Cloud Tops for Windy Clues
Scientists at NASA are finding that with hurricanes, they can look at the cloud tops for clues about the behavior of winds below the hurricane on the Earth's surface. view more (2006-05-17)
'Silent' nighttime acid reflux symptoms can cause poor sleep and sleep apnea
Patients with sleep complaints but no heartburn symptoms suffered episodes of nighttime acid reflux. view more (2005-10-31)
Uric acid may provide early clues to diabetic kidney disease
For patients with type 1 diabetes, increased levels of uric acid in the blood may be an early sign of diabetic kidney disease-appearing before any significant change in urine albumin level, the standard screening test, reports a study in the May 2008 issue of the Clinical Journal of the American Society of Nephrology. view more (2008-03-19)
NASA's TRMM satellite captures Typhoon Melor as it reaches Japan
Melor began as a tropical depression back on the 29th of September 2009 about 1000 miles (~1600 km) east-southeast of Guam in the Northern Mariana Islands. view more (2009-10-09)
Maybe it's raining less than we thought
It's conventional wisdom in atmospheric science circles: large raindrops fall faster than smaller drops, because they're bigger and heavier. view more (2009-06-11)
For hurricanes, storms, raindrop size makes all the difference
When Tropical Storm Gaston hit Richmond, Va., in August 2004, its notable abundance of small and mid-sized raindrops created torrential rains that led to unexpected flash flooding throughout the city and its suburbs. New research from NASA has concluded that tropical cyclones like Gaston produce rain differently than another class of storms called... view more... (2008-06-10)
Self-moisturizing contact lenses, naturally
Even contact lenses are joining the trend to go green. view more (2008-07-09)
Documenting a paradox: smoke decreases rainfall but ultimately increases its intensity
Air pollution and smoke suppress rainfall, but cause the remaining rain amounts to fall in greater intensities, with lightning and hail, says a researcher at the Hebrew University of Jerusalem. The researcher, Prof. Daniel Rosenfeld, was one of a group of scientists that included also participants from Germany, Sweden and Brazil who conducted... view more... (2004-02-25)
Earthquakes in the sky
AN AFTERNOON shower in London may have more in common with an earthquake in California than you`d think, because both processes obey similar statistical rules. The scientists who discovered the link say thinking about rain as a kind of "earthquake in the sky" may help improve models of the weather. ... view more... (2002-05-01)
The Influence Of Disturbance On Tropical Rainforest Biodiversity: End Of A Controversy In Sight
The many species which make up tropical rain forest tree communities show widely differing reactions to environmental factors. This is particularly so with regard to light. Pioneer species, highly heliophile (light-loving or shade-intolerant), establish themselves by taking advantage of canopy light gaps, opened up by treefalls. Rapid growth, a... view more...

Concerns raised over policy to add folic acid to flour
A UK Department of Health committee has now recommended universal fortification of flour with folic acid to reduce the level of neural tube defects. Yet researchers in this week's BMJ warn that we need to be cautious before introducing such a policy. Although the benefits of supplementation are clear, the possible harms of such a policy are not,... view more... (2001-11-20)
Potential candidate chemical for antidepressant effects of exercise found
The antidepressant effects of exercise may be down to a chemical called phenylethylamine, reports a pilot study in the British Journal of Sports Medicine. Although research suggests that exercise is an effective antidepressant, exactly how it works has not been clear. The study focused on 20 healthy young men, average age 22. The young men did... view more... (2001-09-26)
