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)

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)

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)

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... 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)

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... view more (2002-06-07)

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)

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)

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... 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... view more (2004-12-15)

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)

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... view more (2007-08-20)

Hard shell, glowing core
Tiny semiconductor crystals can be prompted to give off light - brighter than conventional dyes and in wavelength ranges that these only produce under certain conditions. Israeli chemist Uri Banin and his coworker Yun-Wie Cao demonstrated this with several core/shell nanocrystals made of the... view more (1999-12-09)

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... view more (2003-07-15)

Method slashes quantum dot costs by 80 percent
In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricey solvents used in quantum dot synthesis with cheaper oils that are commonplace at industrial chemical plants.   view more (2005-09-08)

A First in Integrated Nanowire Sensor Circuitry
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics made of different crystalline materials.... view more (2008-08-05)

Microwave synthesis connects with the (quantum) dots
Materials researchers at the National Institute of Standards and Technology (NIST) have developed a simplified, low-cost process for producing high-quality, water-soluble "quantum dots" for biological research.   view more (2008-06-13)

Biosensors to probe the metals menace
Researchers from CRC CARE are pioneering a world-first technology to warn people if their local water or air is contaminated with dangerous levels of toxic heavy metals and metal-like substances.   view more (2007-08-30)

TREATING POLLUTED LAND WITH CARBON DIOXIDE
First a granular binder containing products which react with carbon is added to the contaminated soil and then carbon dioxide is pumped into the mixture. The three components rapidly combine to produce a cement that is very stable, and although marginally more expensive is immediately available for... view more (1999-11-25)

Nanoporous 'sponge' removes mercury from offshore produced waters
Contaminated water resulting from offshore oil and gas platform drilling contains mercury and other toxic heavy metals.   view more (2006-03-30)

Gold nanoparticles help detect a toxic metal -- mercury
With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and... view more (2007-04-27)

Researchers Can Learn From Antimony and Cot Death Controversy
Professor Fell will be detailing his latest research, due to be published this month in The Analyst, in which he made a careful analysis of a number of toxic metals, such as lead, cadmium and antimony, in newborns and infants. He compared the levels of the metals in those that had died from cot... view more (1999-09-08)

Improved NIST SRM aids lead poisoning detection
Lead in goat blood might not be on the top of your shopping list, but for U.S. medical personnel who each year perform more than 2 million human blood measurements, Standard Reference Material (SRM) 955c from the National Institute of Standards and Technology (NIST) can't be beat.   view more (2007-08-06)
