Dogs keep dying: Too many owners remain unaware of toxic dog food
Even though Diamond, Country Value and Professional brand dog foods have been recalled for containing highly toxic aflatoxins, they have caused at least 100 dog deaths in recent weeks, say Cornell University veterinarians, who are growing increasingly alarmed. view more (2006-01-09)
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)
All change at the Earth's core
It is hard to know what is going on over 3000 km beneath our feet, but until recently scientists were fairly confident that they understood the way the iron atoms in the Earth's core packed together. view more (2007-08-17)
Secrets to antibody's success against West Nile Virus surprise scientists
A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. view more (2005-09-29)
Penn researchers discover key to how SARS virus infects cells
Researchers from the University of Pennsylvania School of Medicine have found that inhibitors of an enzyme called cathepsin L prevent the SARS (severe acute respiratory syndrome) virus from entering target cells. SARS is caused by an emergent coronavirus. view more (2005-08-02)
Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky... view more... (2002-08-16)
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)
HIV-1 kills immune cells in the gut that may never bounce back
People with HIV have been living longer, healthier lives since the development of highly active antiretroviral therapy (or HAART) in 1995. In fact, most patients on the drug regimen do so well that, according to blood tests, their immune cells appear to return to pre-HIV levels. view more (2006-12-05)
Argonne researchers create new diamond-nanotube composite material
Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material - diamond - with the world's strongest structural form - carbon nanotubes. view more (2005-08-31)
Selenium-protein deficiency raises prostate cancer risk
Selenium, an essential dietary mineral that can act as an antioxidant when incorporated into proteins, has been shown in many studies to reduce the incidence of cancers - notably lung, colorectal and prostate. view more (2006-05-23)
Argonne theorist gains new insight into the nature of nanodiamond
The newest promising material for advanced technology applications is diamond nanotubes, and research at the U.S. Department of Energy's Argonne National Laboratory is giving new insight into the nature of nanodiamond. view more (2005-09-12)
UC Santa Barbara researchers light up 'dark' spins in diamond
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins - an initial step towards... view more...

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)
On the cutting edge: Carbon nanotube cutlery
Researchers at the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder (CU) have designed a carbon nanotube knife that, in theory, would work like a tight-wire cheese slicer. view more (2006-11-27)
Are tougher electronic components on the way?
Like modern day alchemists, materials scientists often turn unassuming substances into desirable ones. But instead of working metal into gold, they create strange new compounds that could make the electronic components of the future smaller, faster, and more durable. view more (2006-03-09)
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)
Tough new probe developed for nanotechnologists
Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA, proteins and cells. In all these applications, the... view more... (2005-08-11)
Livermore researchers shed new light on the physical properties of carbon
A team based in Livermore has shed some new light on the phase diagram of carbon at high pressure and temperature. view more (2006-01-25)
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)
