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)

Production of 'mint-scent'
In the industry, many tons of alcohol are used annually, as a starting point for the synthesis of many substances. Alcohol first has to be oxidised, after which aromas such as mint or cinnamon, or substances needed for the production of nylon are produced. Until now heavy metals such as... view more (2000-03-03)

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)

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)

Heavy metals in the Peak District -- evidence from bugs in blanket bogs
Bacteria that consume heavy metals have been found in some of the most contaminated parts of the Peak District in the Southern Pennines and may be changing the pollutants into more toxic forms that could leak out into reservoirs.   view more (2008-04-02)

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)

Greenland Ice Core Reveals History of Pollution in the Arctic
New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions.   view more (2008-08-20)

Sunflowers that love heavy metal
Sunflowers take up uranium twice or even three times better than their maize and soybean counterparts, making them a top 'clean crop' for removing toxic metals from the environment. Scientists at the Centre for Pesticides and Environmental Research, Yugoslavia, studied growth and uranium uptake in... view more (2001-04-01)

Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East... view more (2001-09-07)

Geologists use biotools to understand geosystems
Geologists are now becoming microbiologists in order to discover how biosystems affect geosystems.   view more (2005-10-12)

New sensor system improves detection of lead, heavy metals
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals.   view more (2008-02-13)

Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic... view more (2002-09-11)

Heavy Rainfall on the Increase
With at least one episode of serious flooding already this autumn, new research from the University of East Anglia (UEA) shows that one of the main contributors to flooding, three or more days of heavy rainfall in a row, is on the increase.   view more (2001-11-19)

Exotic Materials Using Neptunium, Plutonium Provide Insight into Superconductivity
Physicists at Rutgers and Columbia universities have gained new insight into the origins of superconductivity - a property of metals where electrical resistance vanishes - by studying exotic chemical compounds that contain neptunium and plutonium.   view more (2008-07-22)

Heavy metal link to mutations, low growth and fertility among crustaceans in Sydney Harbor tributary
Heavy metal pollutants are linked to genetic mutations, stunted growth and declining fertility among small crustaceans in the Parramatta River, the main tributary of Sydney Harbour, new research shows.   view more (2008-08-25)

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)

A new hope for heavy metal contaminated soils
In the 1980s scientists began laboratory studies on metal hyperaccumulator plants, i.e. plants which accumulate exceptionally high concentrations of heavy metals in their above-ground biomass. This coincided with the recognition that a number of serious human diseases are the result of disruptions... view more (2003-12-05)

New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers.   view more (2006-10-13)

Journal of Alzheimer's Disease is devoted to metal ions and neurodegenerative diseases
The recent issue of the Journal of Alzheimer's Disease (Volume 8, Issue 2) published by IOS Press is devoted to "Metal Ions and Neurodegenerative Diseases" and presents a collection of important papers dedicated to uncovering the role of various metals in human neurophysiology and... view more (2006-01-13)

University of Chicago Press Journals
Waifish models have long been accused of setting unrealistic beauty standards and lowering self-esteem.   view more (2006-02-13)

A glass of wine can help find new mineral deposits
In a fascinating piece of spare-time research, CSIRO Exploration & Mining scientist Dr Ryan Noble has found that chemical ingredients in these drinks, including weak organic acids, have the ability to dissolve weakly-bound metals into solution.   view more (2007-09-17)

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)

Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated.   view more (2006-12-12)

Magnetic transistor could 'dial in' quantum effects
A team of theoretical and experimental physicists from Rice University is preparing a unique probe in hopes of "dialing in" elusive quantum states called "quantum criticalities."   view more (2005-12-13)

Heavy drinking increases risk of infection after surgery
Research news from the British Journal of Surgery 17 October 2003: Nosocomial infection is a risk faced by any patient undergoing general surgical procedures. A recent study published in the British Journal of Surgery reveals that some patients increase this inevitable risk to themselves and others... view more (2003-10-20)
