Iron and biological production in the high-latitude North Atlantic
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions. view more (2009-07-08)
Scientists find key to ocean bacterium that helps control greenhouse gas
Scientists are a step closer to understanding how the world's oceans influence global warming - as well supply us with the oxygen we breathe. A study led by Imperial College London has revealed how the most abundant ocean bound photosynthetic bacterium helps control levels of the greenhouse gas, carbon dioxide. Reporting in Nature the researchers... view more... (2003-08-27)
Astronomers Pioneer New Method For Probing Exotic Matter
Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properties of these ultradense objects. view more (2007-08-28)
EPA-led group finds same protein that attracts nutrient iron protects lung from particles
Multi-vitamin products, nutritional supplements and parents tout the need for such mineral elements as calcium, zinc, phosphorus, iron and others. view more (2005-10-05)
New finding points way to foiling anthrax's tricks
University of California, Berkeley, chemists have discovered a trick that anthrax bacteria use to make an end run around the body's defenses, but which may turn out to be their Achilles' heel. view more (2006-12-01)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
Implant bacteria, beware: Researchers create nano-sized assassins
Staphylococcus epidermidis is quite an opportunist. Commonly found on human skin, the bacteria pose little danger. But S. epidermidis is a leading cause of infections in hospitals. view more (2009-06-26)
New properties of the very deep Earth discovered
To truly understand some of the movement we see at the Earth's surface, scientists have to probe deep into the interior. view more (2006-04-28)
Iron controls patterns of nitrogen fixation in the Atlantic
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. view more (2009-11-03)
Neutron stars warp space-time, U-M astronomers observe
Einstein's predicted distortion of space-time occurs around neutron stars, University of Michigan astronomers and others have observed. view more (2007-08-29)
Estrogen Linked to Lowered Immunity in Fish
Exposure to estrogen reduces production of immune-related proteins in fish. This suggests that certain compounds, known as endocrine disruptors, may make fish more susceptible to disease. view more (2009-06-04)
Social parasites of the smaller kind
Cooperation is widespread in the natural world but so too are cheats - mutants that do not contribute to the collective good but simply reap the benefits of others' cooperative efforts. view more (2007-08-27)
New sunscreen ingredient to heal sunburn and help prevent skin cancer
People who suffer from sunburn could soon benefit from a new sunscreen ingredient that actively repairs sunburnt skin and helps prevent the onset of skin cancer. view more (2006-09-08)
Physicists offer new theory for iron compounds
An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors. view more (2009-03-13)
New process offers slick solution to tyre waste
With fossil fuels running out, the oil and gas tied up in the millions of waste tyres discarded each year has been targeted as a possible fuel source for decades. Tyres can yield up to 60% of their weight as fuel oil, but the relatively low price of refined crude means it makes little economic sense to use tyre-derived products. Dr Williams... view more...

New ways to prevent stroke and reduce excess iron in sickle cell anemia
St. Jude Children's Research Hospital will lead a national Phase III clinical trial to investigate whether a new combination treatment can prevent a secondary stroke in children with sickle cell anemia (SCA) and eliminate the need for nightly injections with a drug that reduces iron overload in these patients. view more (2005-09-01)
New study closes in on geologic history of Earth's deep interior
By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, two UC Davis geochemists have produced the first picture of how different isotopes of iron were initially distributed in the solid Earth. view more (2009-06-16)
Study Finds That Nutritionally Enhanced Rice Reduces Iron Deficiency
Breeding rice with higher levels of iron can have an important impact on reducing micronutrient malnutrition, according to a new study in the Journal of Nutrition. view more (2005-12-05)
Iron-arsenic superconductors in class of their own
Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors. view more (2009-04-30)
NASA satellite detects red glow to map global ocean plant health
Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. view more (2009-05-29)
