MERCURY POLLUTION IN BOLIVIAN RIVERS
Mercury contamination in rivers of the Amazon Basin is increasingly a cause for concern. The region's soils, naturally containing abundant heavy metals, are one source of this mercury. Gold mining, which is an increasing activity in the Amazon region since gold fever took hold in the 1970s, is the additional major source. Many studies have been... view more... (1999-09-13)
How does media exposure affect self-esteem in overweight and underweight women?
Overweight women's self-esteem plummets when they view photographs of models of any size, according to a new study in Journal of Consumer Research. And underweight women's esteem increases, regardless of models' size. view more (2009-10-14)
Finnish study identifies factors that increase death in stroke patients ages 15 to 49
Heavy drinking, being 45 to 49 years old, type 1 diabetes or having a preceding infection are associated with more than twice the risk of death in stroke patients 15 to 49 years old, according to a Finnish study. view more (2009-07-10)
What, oh, what are those actinides doing?
Researchers at Pacific Northwest National Laboratory are uniting theory, computation and experiment to discover exactly how heavy elements, such as uranium and technetium, interact in their environment. view more (2007-08-20)
Scientists from the UGR are using olive stones to depollute industrial sewage water
Research carried out by the Department of Chemical Engineering makes it possible to remove chrome, a hard metal which can be dangerous for humans. view more (2007-05-24)
Decoding mushroom's secrets could combat carbon, find better biofuels & safer soils
Researchers at the University of Warwick are co-ordinating a global effort to sequence the genome of one of the World's most important mushrooms - Agaricus bisporus. view more (2007-07-18)
Discovery of the chemically oldest star in the Milky Way
During the last 30 years researchers have tried to find stars that still carry vestiges of the very origin of the Milky Way Galaxy, when it formed from a gigantic collection of gas soon after the Big Bang. The gas of our galaxy, which was presumably composed of hydrogen and helium at the beginning, is continuously polluted by exploding stars that... view more... (2002-10-31)
Could Viagra cause nosebleeds?
If you have had a bad nosebleed recently, think back over the last few days. Have you been taking Viagra? If so, it is worth mentioning it to your doctor, say surgeons writing in the August Journal of the Royal Society of Medicine. Lucy Hicklin and colleagues at St George's Hospital in London describe two case histories where very severe... view more... (2002-07-29)

Metals could forge new cancer drug
Drugs made using unusual metals could form an effective treatment against colon and ovarian cancer, including cancerous cells that have developed immunity to other drugs, according to research at the University of Warwick and the University of Leeds. view more (2009-10-19)
Are tougher electronic components on the way?
Like modern day alchemists, materials scientists often turn unassuming substances into desirable ones. But instead of working metal into gold, they create strange new compounds that could make the electronic components of the future smaller, faster, and more durable. view more (2006-03-09)
Study shows heavy snoring is an independent risk factor for carotid atherosclerosis
A study in the Sept. 1 issue of the journal Sleep shows that objectively measured heavy snoring is an independent risk factor for early carotid atherosclerosis, which may progress to be associated with stroke. view more (2008-09-02)
No evidence that housework as part of ‘active lifestyle’ is good for health
A dose of heavy housework will meet new recommended targets for daily physical activity levels, but there is no evidence that it is good for health, finds research in the Journal of Epidemiology and Community Health. Brisk walking is a much healthier option, shows the study. view more (2002-05-13)
Best Microchemical Study of an Archeomaterial
Bronze age artifacts, physical links between us and people alive 3000 years ago, have long been closely examined with physics-based instruments such as x-ray crystallography and mass spectrometry. Now scrutiny of microchemical surface properties of such ancient bronze in some respects surpasses the diagnostic information gained by... view more... (2001-09-04)
Ayurvedic medicines sold via Internet may contain lead, mercury or arsenic
An analysis of Ayurvedic medicines (based on a traditional medical system commonly used in India) purchased via the Internet found that one-fifth of these products contain levels of lead, mercury or arsenic that exceed acceptable standards, according to a study in the August 27 issue of JAMA. view more (2008-08-27)
Major grant backs science behind UK metals industries
A world-leading University of Sheffield research institute whose scientific input is boosting the UK metals industries' global competitiveness has itself received a boost worth almost £4m. IMMPETUS, the Institute for Microstructural and Mechanical Process Engineering, launches the next phase of its work next week with the help of a five-year... view more... (2002-10-17)
Cornell Research is Key - New Company Promises to Detoxify Pollutants with Plant Biologicals
A company formed as a spin-off from research conducted at Cornell University, the University of Surrey and the University of Naples, Italy, will provide biological systems that detoxify heavily contaminated soil and water. "Our goal is to develop biological products with broad capabilities for the detoxification of polluted soils or sediments... view more... (2003-04-30)
Bleeding disorders going undiagnosed; new guidelines to help
Nearly one percent of the population suffers from bleeding disorders, yet many women don't know they have one because doctors aren't looking for the condition, according to researchers at Duke University Medical Center. view more (2009-06-02)
Heavy smoking cuts women's chance of pregnancy — even with donated oocytes
Heavy smoking may reduce female fertility by directly affecting the uterus - making it less receptive and reducing the chances the embryo will implant, according to research published on line (Thursday 9 November) in Europe's leading reproductive medicine journal Human Reproduction. view more (2006-11-09)
Scientists describe new way to peer inside bacteria
As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria. view more (2005-08-30)
