The Sky Is Not Falling: Pollution in eastern China cuts light, useful rainfall
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country. view more (2009-08-17)
Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and marine chemists. view more (2007-09-10)
Bacteria checkmate yeasts and moulds
Lactic acid bacteria are found in many foods, for example, yoghurt, cheese or sauerkraut. These bacteria are desirable, as they change the taste and consistency of a raw material in such a way that a completely new foodstuff is created. In the manufacture of cheese, propionic acid bacteria also play an important role. They are responsible for the... view more... (2005-04-01)
High salicylic acid content in fruits and vegetables may explain protection from heart disease among vegetarians
The high salicylic acid content of fruits and vegetables may explain why vegetarians suffer less heart disease and bowel cancer than meat-eaters, suggests research in the Journal of Clinical Pathology. Salicylic acid is the main anti-inflammatory component of aspirin, which is widely prescribed to reduce the risk of heart attacks. Research also... view more... (2001-06-26)
Governments committing "public health malpractice" over flour fortification
The failure of European governments, including the United Kingdom, to fortify flour with folic acid has allowed a continuing epidemic of preventable human illness, according to an editorial in this week's BMJ. Fortification could save as many lives as are lost each year in vehicle crashes, writes Professor Godfrey Oakley of Emory University in the... view more... (2002-06-05)
Dutch diet contains too little folic acid
The average Dutch person consumes about 85% of the recommended daily intake of folic acid. Furthermore, it is estimated that our bodies fail to absorb no less than one quarter of the folic acid in food. These findings were made by Alida Melse-Boonstra during her doctoral research, which she carried out at the Wageningen Centre for Food Sciences... view more... (2003-09-05)
Link possible between pet food contamination and baby formula contamination
A study published in the November issue of a scientific journal, Toxicological Sciences, which is published by Oxford Journals on behalf of the Society of Toxicology, describes the kidney toxicity of melamine and cyanuric acid based on research that was done to characterize the toxicity of the compounds that contaminated pet food in North America... view more...

Massage after exercise myth busted by Queen's research team
A Queen's University research team has blown open the myth that massage after exercise improves circulation to the muscle and assists in the removal of lactic acid and other waste products. view more (2009-05-08)
Are certain congenital birth defects and heart disease linked?
The study implicates homocysteine, a chemical by-product of human metabolism. Homocysteine is particularly important for cell growth and is regulated by enzymes, the activities of which are partly genetically determined, and partly affected by diet, including the levels of vitamins B6, B12, and folic acid in the blood. view more (1999-11-15)
Scientists discover why plague is so lethal
Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology. view more (2008-05-05)
Rainfall research could help flood control
A new method of measuring rainfall accurately could help to improve flood control. Following a study in the Bolton area, the method, devised by the University of Essex and using dual-frequency microwave links, will now be tested in Italy and Germany. The recent devastating floods in central Europe have demonstrated the need for accurate rainfall... view more... (2002-09-27)
Rain showers may be caused by vortices in the air
The Delft researchers calculated how hundreds of thousands of water droplets contained in about one litre of cloud move and grow. During this process, it would seem that tubular-shaped vortices a few centimetres in size are formed and that these force the droplets outwards by centrifugal force, so that they congregate at the edge. For rain to be... view more... (1999-11-09)
High doses of folic acid may help to prevent stomach cancer
High doses of folic acid may help to prevent digestive tract cancers, suggests animal research reported in Gut. view more (2001-12-17)
Pitt professor says harmful byproducts of fossil fuels could be higher in urban areas
Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize. view more (2007-10-23)
A safe folic acid boost from flour
Public consumption of folic acid from fortified flour at current mandated US levels (100micro-gram/day) and at double this amount is probably safe, at average intakes, according to an article published today in the open access journal BMC Public Health. view more (2007-03-22)
Acid-reducing medicines may lead to dependency
Treatment with proton pump inhibitors (PPIs) for eight weeks induces acid-related symptoms like heartburn, acid regurgitation and dyspepsia once treatment is withdrawn in healthy individuals. view more (2009-07-01)
Scientists question folic acid fortification
Scientists at the Institute of Food Research have highlighted possible consequences of fortifying flour with folic acid due to new evidence of how it is absorbed by the body. view more (2007-11-05)
Food Supplementation With Folic Acid Could Substantially Reduce Neural-Tube Defects (p 2047)
A public-health initiative to enrich cereal grain foods in Canada with folic acid has halved the prevalence of neural-tube defects among both unborn and newborn children, report authors of a research letter in this week's issue of THE LANCET. Folic acid tablet supplementation around the time of conception is known to dramatically reduce the risk... view more... (2002-12-18)
Australia's climate: Drought and flooding in annual rings of tropical trees
Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation. view more (2009-06-12)
Satellites can help Arctic grazers survive killer winter storms
Rain falling on snow sounds like a relatively harmless weather event, but when it happens in the far north it can mean lingering death for reindeer, musk oxen and other animals that normally graze on the Arctic tundra. view more (2008-03-19)
