Diamonds from outer space — Geologists discover origin of Earth's mysterious black diamonds
If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space. view more (2007-01-10)
Alloy of hydrogen and oxygen made from water
Water, the only indispensable ingredient of life, is just about the most versatile stuff on Earth. Depending on its temperature we can heat our homes with it, bathe in it, and even strap on skates and glide across it, to name only the most common of its many forms. When subjected to high pressures, however, water can take any of more than 15... view more... (2006-10-27)
Nanotech discovery could have radical implications
It has been 20 years since the futurist Eric Drexler daringly predicted a new world where miniaturized robots would build things one molecule at a time. The world of nanotechnology that Drexler envisioned is beginning to come to pass, with scientists conjuring new applications daily. view more (2005-12-01)
Z machine melts diamond to puddle
Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid. view more (2006-11-06)
CBEN: Buckyball aggregates are soluble, antibacterial
In some of the first research to probe how buckyballs will interact with natural ecosystems, Rice University's Center for Biological and Environmental Nanotechnology finds that the molecules spontaneously clump together upon contact with water, forming nanoparticles that are both soluble and toxic to bacteria. view more (2005-06-23)
Liquid CO2 drives rapid thrust of diamond-bearing structures
Freeze-dried ice cream looks like the original product, and even tastes pretty good, but "drying" ice cream at room temperature would leave a sour-smelling, sloppy mess. view more (2007-05-03)
Minerals go 'dark' near Earth's core
Minerals crunched by intense pressure near the Earth's core lose much of their ability to conduct infrared light, according to a new study from the Carnegie Institution's Geophysical Laboratory. view more (2006-05-26)
Diamond by-product of hydrogen production and storage method
There may not be a pot of gold at the end of the rainbow, but there appears to be nanocrystalline diamonds at the end of a process to produce and store hydrogen using anthracite coal. view more (2006-06-26)
New nanotech products hitting the market at the rate of 3-4 per week
New nanotechnology consumer products are coming on the market at the rate of 3-4 per week, a finding based on the latest update to the nanotechnology consumer product inventory maintained by the Project on Emerging Nanotechnologies (PEN). view more (2008-04-25)
Researchers locate mantle's spin transition zone, leading to clues about Earth's structure
Researchers have located the spin transition zone of iron in Earth's lower mantle, a discovery which has profound geophysical implications. view more (2007-09-24)
Nanoengineers mine tiny diamonds for drug delivery
Northwestern University researchers have shown that nanodiamonds -- much like the carbon structure as that of a sparkling 14 karat diamond but on a much smaller scale -- are very effective at delivering chemotherapy drugs to cells without the negative effects associated with current drug delivery agents. view more (2007-10-15)
Rensselaer researchers create tiny magnetic diamonds on the nanoscale
Diamonds have always been alluring, but now a team of scientists has made them truly magnetic - on the nanoscale. view more (2005-09-13)
WATER HELPS TO FIND DIAMONDS
For many years geologists at the Research Institute of Geological and Geoecological Problems, Cheboksary, have been studying the River Karla region, which includes the south-western part of Chuvashia and a part of the Tatar Republic. The scientists used a new isotope-hydrogeochemical method, while searching for kimberlitic pipes. They achieved... view more... (2002-08-06)
Durham diamond expert reports to the White House
The US Government has called in a University of Durham geologist for advice on diamonds in an effort to crack down on the illegal gems-for-arms trade. Dr Graham Pearson is one of a group of international experts and government representatives invited tot he White House Diamond Conference, convened in conjunction with The National Economic Council,... view more...

UCSB researchers show how to make polymeric micro- and nanoparticles
Researchers in the College of Engineering at UC Santa Barbara have discovered how to make polymeric micro- and nanoparticles in a wide variety of different shapes and sizes using commonly-available lab chemicals and equipment. view more (2007-07-10)
Scientists levitate diamond, lead and platinum
Scientists at The University of Nottingham have successfully levitated diamond and some of the heaviest elements, including lead and platinum. view more (2005-05-11)
Circumstellar space: Where chemistry happens for the very first time
Picture a cool place, teeming with a multitude of hot bodies twirling about in rapidly changing formations of singles and couples, partners and groups, constantly dissolving and reforming. view more (2007-08-01)
No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The... view more... (2004-01-12)
Medicine and Biology at the Institute of Physics Congress Brighton Conference Centre, 27-30 March
In-Vitro Bio-Medical Sensing Monday 27 March 2000 Bodily fluids can be screened for the presence of infections by a range of tests using relatively simple technology. X-rays can analyse molecular structures and may be used to distinguish between healthy, benign and malignant breast tissue. In other areas of research, microtechnology is playing an... view more...

Laser-induced shocks in diamond anvil can achieve pressures inside supergiant planets
Combining diamond anvils and powerful lasers, laboratory researchers have developed a technique that should be able to squeeze materials to pressures 100 to 1,000 times greater than possible today, reproducing conditions expected in the cores of supergiant planets. view more (2007-05-03)
