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... view more (1999-09-13)

Growing green gold
A new way to make gold form inside the cells of a micro-organism is published today in the Institute of Physics journal Nanotechnology. Researchers from the National Chemical Laboratory and the Armed Forces Medical College, both in Pune, India, have been using “green chemistry” to... view more (2003-06-06)

Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.   view more (2007-08-23)

Gold beads show previously unseen parts of the eye
A new study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO), shows that gold beads injected into eye tissue can be used to obtain images of important structures in the orbit that cannot be seen with... view more (2006-05-01)

Scientists peel away the mystery behind gold's catalytic prowess
Few materials have exercised as much of a hold on the human imagination, or on human history, as has gold.   view more (2008-09-05)

Bacteria Precipitate Gold
Roman A. Amosov and a team of Russian scientists from the Central Institute for Geological Exploration of Non-ferrous and Noble Metals, Institute of Paleontology, Russian Academy of Sciences, and from the Institute of Microbiology, Russian Academy of Sciences, led by, have managed to simulate in... view more (2002-07-26)

Gold nanoparticles prove to be hot stuff
Gold nanoparticles are highly efficient and sensitive "handles" for biological molecules being manipulated and tracked by lasers, but they also can heat up fast-by tens of degrees in just a few nanoseconds-which could either damage the molecules or help study them.   view more (2006-09-01)

Gold for the jubilee year
The Queen's Golden Jubilee year has been suitably marked by two British students, who were awarded gold medals at the International Biology Olympiad, held in Latvia.   view more (2002-07-16)

Scientists discover how gold eases pain of arthritis
Scientists at Duke University Medical Center may have solved the mystery surrounding the healing properties of gold - a discovery they say may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases.   view more (2007-10-23)

When gold becomes a catalyst
Gold has always been perceived as a precious material: you win a gold medal when you prove to be the best in a competition; you only get a Gold credit card when you are a preferential customer, and the jewelry made of this material is amongst the most valuable.   view more (2006-06-23)

Gold Nanoparticles Emit Intense Heat, Study Finds
Nanoparticles of gold can act as tiny, precise and powerful heaters, which potentially could be used in biomedical applications, according to a new study.   view more (2006-03-31)

Adenine 'tails' make tailored anchors for DNA

Gold in the realm of dwarves
"Man has been fascinated by gold since ancient times," says a bland introduction to related scientific studies. The fact that there is still room for surprises was shown by a recent publication: Nanoparticles of the precious metal behave differently from those of its close relatives.   view more (2004-10-25)

The nanoworld of corrosion
The effect of corrosion has an impact on about 3% of the world's Gross Domestic Product. From a positive point of view, however, chemical attack of metal surfaces may result into surface nano-structures with very interesting technological applications such as catalysts and sensors.   view more (2006-02-10)
