Tiny diamonds on Santa Rosa Island give evidence of cosmic impact
Nanosized diamonds found just a few meters below the surface of Santa Rosa Island off the coast of Santa Barbara provide strong evidence of a cosmic impact event in North America approximately 12,900 years ago. view more (2009-07-22)
Getting the most out of gemstones
"We were astounded when our customer, Markus Wild, approached us and we were not at all certain whether mathematics could offer a solution for the very complex problem of volume optimization of gemstones," says Dr. Anton Winterfeld from the Fraunhofer Institute for Industrial Mathematics ITWM. view more (2009-06-26)
IUPUI study finds living near fast food outlet not a weighty problem for kids
A new study by Indiana University-Purdue University Indianapolis (IUPUI) researchers contradicts the conventional wisdom that living near a fast food outlet increases weight in children and that living near supermarkets, which sell fresh fruit and vegetables as well as so called junk food, lowers weight. view more (2009-06-17)

6 North American sites hold 12,900-year-old nanodiamond-rich soil
Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team. view more (2009-01-05)
Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen. view more (2008-09-04)
X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks? view more (2008-08-13)
Diamond conference at the Goethe University

University of Pennsylvania Engineers Reveal What Makes Diamonds Slippery at the Nanoscale
They call diamonds "ice," and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably low friction, making it an ideal material or coating for seals, high performance tools and high-tech moving parts. view more (2008-06-24)
Diamonds Are Forever Revealing New Insights into Earth's Development
Diamonds will take center stage this month in countless wedding ceremonies and other celebrations. In addition to their usual role as symbols of enduring love and fidelity, diamonds are now also helping geologists unravel clues about how the earth's precious metal mineralization was formed and why diamonds and some of these metals are found in... view more...

Data mining personnel
With the dark clouds of global recession now is the time for companies to make the most of their most valuable assets - their personnel. Writing in a forthcoming issue of the International Journal of Business Information Systems, researchers in India explain how data mining could help unearth the diamonds in the rough. view more (2008-04-23)
Fake diamonds help jet engines take the heat
Engineers are developing a technology to coat jet engine turbine blades with zirconium dioxide -- commonly called zirconia, the stuff of synthetic diamonds -- to combat high-temperature corrosion. The zirconia chemically converts sand and other corrosive particles that build up on the blade into a new, protective outer coating. In effect, the... view more... (2008-03-18)
Smithsonian researcher probes Hope Diamond's fiery red glow
A study released in the January 2008 edition of the journal Geology proves that a blue diamond's rare appeal goes far beyond its beauty. The study was conducted by Jeffrey Post, curator of the National Gem Collection and mineralogist, at the Smithsonian's National Museum of Natural History. view more (2008-01-09)
Hope Diamond's phosphorescence key to fingerprinting
