Sulfur in marine archaeological shipwrecks -- the 'hull story' gives a sour aftertaste
Advanced chemical analyses reveal that, with the help of smart scavenging bacteria, sulfur and iron compounds accumulated in the timbers of the Swedish warship Vasa during her 333 years on the seabed of the Stockholm harbour. view more (2008-05-19)
The prevalence of gluten-sensitive enteropathy in iron-deficient anemia patients
Gluten sensitive enteropathy (GSE) is an autoimmune enteropathy due to food gluten intolerance in genetically predisposed people. view more (2009-01-05)
A Grab for Iron - Breakthrough for Innsbruck Scientists
Nearly all organisms need iron to survive, even mould. For people with a weakened immune system such fungi pose a deadly threat. Scientists from Innsbruck (Austria) have now been able to genetically block the iron metabolism of Aspergillus fumigatus mould and thus render it harmless to humans. This discovery opens up completely new paths for... view more... (2004-10-25)
Toward a systems biology map of iron metabolism
Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a systems biology map of iron metabolism. view more (2009-04-29)
Wheat gene may boost foods' nutrient content
Researchers at the University of California, Davis; the U.S. Department of Agriculture; and the University of Haifa in Israel have cloned a gene from wild wheat that increases the protein, zinc and iron content in the grain, potentially offering a solution to nutritional deficiencies affecting hundreds of millions of children around the world. view more (2006-11-27)
Do the hyper-coordinate planar transition metal atoms exist?
A study reported in Vol 51, Issue 7 (July, 2008) of Science in China Series B: Chemistry has shown that wheel-shaped structures with octa- and enneacoordinate planar cobalt, iron and nickel centered in perfect octagonal and enneagonal boron rings, are stable on corresponding potential hyper-surfaces. This suggests that the central element bonding... view more... (2008-07-01)
Filming an ultra-fast biological reaction essential to life
A team of scientists from the USA in collaboration with staff at the European Synchrotron Radiation Facility1 (Schotte et al) have managed to film a protein at work in unprecedented detail. The protein is the oxygen-storing molecule myoglobin, which plays a central role in the production of energy in muscles. The motion of the protein was recorded... view more... (2003-06-24)
Virtual Reality - NPL develops new software for aluminium alloy property prediction
The National Physical Laboratory (NPL) has developed a solution to the arduous and expensive task of obtaining reliable values for material properties for aluminium alloys. It comes in the form of the Virtual Measurement System (VMS), a software tool that allows engineers, material scientists and researchers working with aluminium alloys to... view more... (2003-11-13)
New theory for latest high-temperature superconductors
Physicists from Rice and Rutgers universities have published a new theory that explains some of the complex electronic and magnetic properties of iron "pnictides." In a series of startling discoveries this spring, pnictides were shown to superconduct at relatively high temperatures. The surprising discoveries created a great deal of... view more... (2008-08-14)
Unexpected link between gene in liver and iron overload
A new study in the December Cell Metabolism reveals an unexpected connection between a tumor suppressor gene in the liver and the normally careful control over the amount of iron absorbed from the diet. view more (2005-12-07)
Iron Age "Housing Estate" Uncovered by University of Warwick Researchers - Earliest Evidence of Settlement in Coventry
Researchers at the University of Warwick have discovered the outline of 15 late iron age roundhouses on the University of Warwick's campus. This discovery marks the earliest evidence of settlement within the modern boundary of the City of Coventry. The 15 building outlines uncovered so far appear to be just the edge of a larger complex of iron age... view more... (2002-08-01)
Nature Points the way to a sustainable hydrogen economy
"This is an exciting early step in developing a sustainable system for producing electricity from hydrogen" said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). "In Nature iron-sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal... view more... (2005-02-10)
Key site in iron metabolism aids in diagnosing anemia of chronic disease
University of Utah School of Medicine researchers have developed a new tool that facilitates diagnosis of anemia related to chronic illness, as well as diseases of iron overload. The results of a study detailing the new tool are published in the August 2008 issue of the journal Cell Metabolism, a publication of Cell Press. view more (2008-08-06)
Electronic equipment gets a second life
As of next year, electronics manufacturers in Europe will be required to take back and partially recycle old equipment. Beginning in 2006, electronics must be completely lead-free. An industry conference in Berlin sheds light on how companies can meet these regulations. view more (2004-08-27)
Polar clouds take a 'bite' out of meteoric iron
Polar clouds are known to play a major role in the destruction of Earth's protective ozone layer, creating the springtime 'ozone hole' above Antarctica. Now, scientists have found that polar clouds also play a significant role in removing meteoric iron from Earth's atmosphere. Polar clouds have been widely studied in recent years, because of their... view more... (2004-04-14)
Ancient Chinese remedy shows potential in preventing breast cancer
A derivative of the sweet wormwood plant used since ancient times to fight malaria and shown to precisely target and kill cancer cells may someday aid in stopping breast cancer before it gets a toehold. view more (2005-12-20)
Iron supplement as treatment for anaemia in infants
In Vietnam, nearly 60% (1) of children under two years old suffer from anaemia owing to iron deficiency. This is a disease which affects their growth and psychomotor development and reduces their resistance to infections. The iron deficit stems essentially from a diet poor in the easily assimilated form of this element. Rice broth, traditionally... view more... (2003-05-22)
News Release : Carbon Acts Like Rustoleum Around Hydrothermal Vents
The cycling of iron throughout the oceans has been an area of intense research for the last two decades. Oceanographers have spent a lot of time studying what has been affectionately labeled the Geritol effect ever since discovering that the lack of iron is a reason why phytoplankton grow lackadaisically in some of the most nutrient-rich surface... view more...

Hydrogen protects nuclear fuel in final storage
When Sweden's spent nuclear fuel is to be permanently stored, it will be protected by three different barriers. Even if all three barriers are damaged, the nuclear fuel will not dissolve into the groundwater, according to a new doctoral dissertation from Chalmers University of Technology in Sweden. view more (2009-04-27)
Earth's magnetic field really did reverse itself
NWO researchers have developed an improved method of identifying the magnetic signals in old geological strata. The researchers used the new method to show that the earth's magnetic field really did reverse itself ten million years ago. Particles of iron in sediments orient themselves in accordance with the local magnetic field of the earth. As... view more... (2001-11-27)
