Singapore scientists synthesize gold to shed light on cells' inner workings
Highly fluorescent gold nanoclusters for sub-cellular imaging have been synthesized by researchers at the Institute of Bioengineering and Nanotechnology (IBN). view more (2009-04-16)
Researchers Find Controls to Gold Nanocatalysis
Researchers at the Georgia Institute of Technology have made a discovery that could allow scientists to exercise more control over the catalytic activity of gold nanoclusters. view more (2006-08-10)
Controlling the Size of Nanoclusters: First Step in Making New Catalysts
Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have developed a new instrument that allows them to control the size of nanoclusters - groups of 10 to 100 atoms - with atomic precision. view more (2008-07-10)
NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon monoxide (CO) into harmless carbon dioxide at room... view more...

Scientists discover how nanocluster contaminants increase risk of spreading
For almost half a century, scientists have struggled with plutonium contamination spreading further in groundwater than expected, increasing the risk of sickness in humans and animals. view more (2008-04-18)
Amanda Fisher receives EMBO Gold Medal
Amanda Fisher, group head at the MRC Clinical Science Centre, London (U.K.), is this year`s winner of the EMBO Gold Medal. This prestigious prize is awarded by EMBO in recognition of Amanda Fisher`s outstanding work on nuclear organization and gene expression as well as for her research on the molecular characterisation of the AIDS virus (HIV).... view more...

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)
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 develop an eco-friendly way to make tiny gold particles... view more...

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)
Withdrawal syndrome after consumption of 'Spice Gold'
A clinical report from Dresden supports the impression that "Spice Gold" is strongly addictive. view more (2009-07-09)
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 Magnetic Resonance Imaging (MRI) or other imaging... view more...

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 the laboratory the process of precipitation of gold... view more...

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)
New rotors could help develop nanoscale generators
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. view more (2009-05-28)
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
Researchers from the National Institute of Standards and Technology (NIST), the Naval Research Laboratory (NRL) and the University of Maryland (UMD) have demonstrated a deceptively simple technique for chemically bonding single strands of DNA to gold. view more (2006-12-27)
