A promising new approach to cadmium induced hepatoxicity: Cytoprotective effect of midkine
Cadmium comes from a wide variety of sources in the environment and from industry and is extremely toxic to humans. Environmental exposure can occur via the diet and drinking water. view more (2008-01-17)
Low level cadmium exposure linked to lung disease
New research suggests that cadmium is one of the critical ingredients causing emphysema, and even low-level exposure attained through second-hand smoke and other means may also increase the chance of developing lung disease. view more (2008-08-20)
Global warming increases oyster sensitivity to pollution
Do you enjoy eating oysters on a hot sunny afternoon? Make the most of it - it may not last forever. Research has shown that global warming increases the sensitivity of oysters to metal pollution, causing a deadly threat to populations in polluted areas. view more (2005-07-12)
Snails snack on poison metals
SOILS tainted with heavy metals from industrial pollution and sewage sludge may poison organisms that live in the soil far more readily than thought. The finding raises fears that unexpectedly high levels of toxins are getting into the food chain. Contaminated soils are given hazard ratings that are based on the key assumption that organisms can... view more... (2002-12-18)
Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops
Deficiencies of micronutrients such as Iron and Zinc commonly limit plant growth and crop yields. Dartmouth Professor Mary Lou Guerinot is conducting research to better understand the mechanisms of micronutrient uptake, distribution and regulation. view more (2006-08-07)
Rising ocean temperatures, pollution have oysters in hot water
Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy. view more (2006-10-11)
Garlic Helps Protect Our DNA
Mutagens damage DNA. Consequently, antimutagens have to repair these damages. As the effects on DNA differ, the ways of reparation also vary. However, the mechanism of the activity of some antimutagens has not been found yet. A team headed by Professor G.D. Zasukhina at N.I. Vavilov Institute of General Genetics (http://www.vigg.ru/vigg-en.htm),... view more... (2002-06-07)
Study shows transfer of heavy metals from water to fish in Huelva estuary
A team of researchers from the University of Cadiz has confirmed that zinc, copper and lead are present at high levels in the water and sediments of the Huelva estuary, and have studied how some of these heavy metals are transferred to fish. view more (2009-06-16)
New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). view more (2009-02-19)
BIOMARKERS IN ADOLESCENTS COULD PROVIDE MEASUREMENT FOR ENVIRONMENTAL POLLUTION (p 1660)
Biological markers in adolescents could be a reliable measure of exposure to environmental pollutants, according to a study in this week's issue of THE LANCET which highlights how increased exposure among adolescents slows sexual development. Human exposure to chemicals is normally monitored by measurement of environmental pollutants externally.... view more... (2001-05-23)
Tiny crystals promise big benefits for solar technologies
Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials that previously thought. view more (2006-01-05)
Truly sick or simply scared?
Scientists at Pacific Northwest National Laboratory have discovered a way to increase the sensitivity of test strips that will enable creation of a portable biosensor that can address a major concern associated with incidents involving chemical or nerve agents - the need to quickly distinguish between individuals who have been exposed and the... view more...

Heavy Metal Rocks Plant Cells too
Heavy metals can trigger widely varying stress reactions in plants. A team at the Campus Vienna Biocenter was now able to provide evidence for this in a research funded by the Austrian Science Fund (FWF). The results, now awaiting publication, are an important basis to comprehend how plants cope with an increase in heavy metal concentrations in... view more... (2004-09-22)
Quantum dot recipe may lead to cheaper solar panels
Rice University scientists today revealed a breakthrough method for producing molecular specks of semiconductors called quantum dots, a discovery that could clear the way for better, cheaper solar energy panels. view more (2007-05-03)
Scientists Reveal The Dangers of Counterfeit Cigarettes
Scientists at the Universities of Glasgow and St Andrews have discovered high levels of a cancer-causing toxic metal in counterfeit cigarettes, widely available in the UK. The fakes are not only illegal but pose an extra health hazard to smokers buying them. The discovery was made when examining samples of the most popular cigarette brands sold... view more...

Sun exposure seems to reduce risk of multiple sclerosis
Higher sun exposure during childhood and early adolescence is associated with a reduced risk of multiple sclerosis, finds a study in this week's BMJ. Multiple sclerosis is more common at higher latitudes, which generally have lower levels of ultraviolet radiation. The study was carried out in Tasmania, which is located at high latitude and has a... view more... (2003-08-06)
Papers recently published online by Nature and the Nature Research Journals
NATURE MEDICINE(http://www.nature.com/naturemedicine) [1] Cadmium's disguise does damage to estrogen-sensitive tissues DOI: 10.1038/nm902 (http://dx.doi.org/10.1038/nm902) With 15,000 tons produced each year for batteries, alloys, and pigments, the heavy metal cadmium is one of the most serious environmental pollutants. Chronic exposure can... view more... (2003-07-15)
Nanomanufacturing: Systematic study of nanostructure growth yields production 'road map'
Researchers have taken an important step toward high-volume production of new nanometer-scale structures with the first systematic study of growth conditions that affect production of one-dimensional nanostructures from the optoelectronic material cadmium selenide (CdSe). view more (2005-11-01)
Exposure to phthalates may be a risk factor for low birth weight in infants
Many parents worry about their child's exposure to phthalates, the chemical compounds used as plasticizers in a wide variety of personal care products, children's toys, and medical devices. view more (2009-06-25)
Three out of four junior doctors risk potential HIV infection during course of work
Three out of four junior doctors are at potentially high risk of HIV infection at some time during their careers, shows a survey in Sexually Transmitted Infections. Yet two thirds were unaware that they could be treated immediately afterwards to minimise the risk of infection. view more (2001-11-20)
