Synthetic catalyst mimics nature's 'hydrogen economy'
By creating a model of the active site found in a naturally occurring enzyme, chemists at the University of Illinois have described a catalyst that acts like nature's most pervasive hydrogen processor. view more (2009-05-19)
A Zen discovery: Unrusted iron in ocean
Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or - a surprising new study finds - float up from the sea floor. view more (2009-02-09)
A better screening test for infant iron deficiency?
A unique blood test detects iron deficiency in infants earlier and more accurately than the commonly used hemoglobin screening test. view more (2005-08-24)
XMM-Newton takes astronomers to a black hole's edge
Using new data from ESA's XMM-Newton spaceborne observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy. view more (2009-05-28)
Arsenic discharged from landfills, says Dartmouth research
A group of researchers at Dartmouth have studied the concentrations of toxic metals at the former Coakley Landfill in North Hampton, N.H. They've found that while the level of iron and some other contaminants decreased, the level of arsenic slightly increased. view more (2005-12-05)
MIT forges greener path to iron production
MIT engineers have demonstrated an eco-friendly way to make iron that eliminates the greenhouse gases usually associated with its production. view more (2006-09-13)
A Bridge to History
A successful operation to rescue an historically unique cast iron bridge, the only surviving remnant of the early nineteenth century 'Innocent' Railway from Dalkeith into Edinburgh, was awarded a Special Commendation by the Institution of Civil Engineers on Friday 21 March 2003. The 20 foot wide Braid Burn Bridge at Duddingston in Edinburgh, which... view more... (2003-03-21)
Plymouth Leads 'healthy Oceans' Research
Plymouth researchers will be presenting new research findings at an international conference they are hosting in the city next month. Professor Paul Worsfold, Co-director of Plymouth Environmental Research Centre (PERC), heads the Plymouth team working on a three-year research project which investigates the role of iron in ocean productivity and... view more...

MIT uncovers key blood protein
Scientists working in the only lab at MIT doing hematology research have uncovered a protein that plays a key role in the recycling of iron from blood. view more (2007-10-12)
Iron overload
One in every three hundred people in the US and UK has the potential to develop hemochromatosis, a disorder which overloads the body with iron. So why do only some of them go on to develop the disease? American scientists have been studying the genetic make-up of patients with hemochromatosis, a potentially fatal disease. Sufferers have high... view more... (2001-04-04)
University of Toronto chemists uncover green catalysts
A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours. view more (2009-04-14)
Iron isotopes as a tool in oceanography
New research involving scientists from the National Oceanography Centre, Southampton (NOCS) highlights the potential utility of iron isotopes for addressing important questions in ocean science. view more (2009-07-31)
Separating the brain's 'bad' from 'good' iron
Duke University chemists are developing ways to bind up iron in the brain to combat the neurological devastation of Parkinson's and Alzheimer's diseases. view more (2007-08-24)
Iron on its route to the sea-floor: A new path
Iron dust, the rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or--a surprising new study finds--float up from the sea floor in the material spewed from hydrothermal vents. view more (2009-02-09)
Topical Papers in Biochemical Journal - Selective determination of mitochandrial chelatable iron in viable cells with a new fluorescent sensor
This paper by Petrat and colleagues marks an important advance in our understanding of the regulation of iron in the human body. Real-time changes in the concentration of the ionized form of iron (Fe2+) can now be monitored within the mitochondria of living cells for the first time, thanks to the technique described in this article. For some... view more... (2002-02-08)
Clemson chemists discover new way antioxidants fight debilitating diseases
Cancer, cardiovascular diseases, Parkinson's and Alzheimer's are often linked to DNA damage that occurs when metal ions in the body such as iron and copper produce reactive oxygen compounds that damage human cells. view more (2007-08-20)
Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops
Deficiencies of micronutrients such as Iron and Zinc commonly limit plant growth and crop yields. Dartmouth Professor Mary Lou Guerinot is conducting research to better understand the mechanisms of micronutrient uptake, distribution and regulation. view more (2006-08-07)
Metabolic insight to illuminate causes of iron imbalance
New insight into key players in iron metabolism has yielded a novel tool for distinguishing among root causes of iron overload or deficiency in humans, the researchers report in the August issue of Cell Metabolism, a publication of Cell Press. While the body needs iron to produce hemoglobin, a substance in red blood cells that enables them to... view more... (2008-08-06)
New clues about the Earth's movements
Synchrotron light has just revealed new clues about how the Earth moves. A team of scientists (Dubrovinsky et al) from four different countries and different fields of expertise have come to the ESRF to study materials submitted to extreme conditions of pressure and temperature, similar to those found at the boundary between the core and the... view more...

Trojan horse strategy defeats drug-resistant bacteria
A new antimicrobial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist. The joint project, conducted at the UW, the University of Iowa, and the University of Cincinnati, will be... view more... (2007-03-19)
