Redox-active iron is a sensor of cognitive impairment associated with Alzheimer's disease
An innovative discovery has been reported that highlights the problems that oxidative stress resulting from iron cumulated in the human brain can generate in relation with the pathogenesis of Alzheimer's disease (AD), the brain disorder affecting almost 30 million throughout the world.   view more (2008-04-07)

Iron supplements may relieve unexplained tiredness in young women
Unexplained tiredness is common in young women. In this week's BMJ, researchers find that non-anaemic women with fatigue may benefit from taking an iron supplement. The study took place in Switzerland and involved 136 women aged 18 to 55 who consulted a doctor with fatigue, but who were not... view more (2003-05-22)

From food scraps to fuel cell
EMBARGOED UNTIL WEDNESDAY 9 OCTOBER 2002 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk SCRAPS of food could soon be helping power your home, thanks to an ultra-cheap bacteria-driven battery. Its developers hope... view more (2002-10-09)

Ironing out malnutrition
Two of the three keys are in place to unlock the secret to controlling and enhancing plant iron uptake. Scientists are poised to identify the final step in the process that could supply the world with iron-rich crops. Collaboration between American and French scientists has led to the... view more (2001-04-02)

Mom's nutrition during pregnancy related to child's behavior at age three
Children born to teenage mothers who were iron deficient early in their pregnancies were less active at age 3 than the children of iron sufficient moms, a Penn State study has shown.   view more (2006-04-04)

Microbial Fuel Cells: Optimization Of The Anode Compartment For Improved Electron Transfer
A microbial fuel cell mimics a biological system, in which bacteria do not directly transfer the energy-rich electrons gained out of the feeding to their characteristic electron acceptor. Instead, the electrons are diverted towards an electrode (anode) and subsequently conducted over a resistance... view more (2003-11-14)

Iron Can Have Negative Side Effects On People With Kidney Disease
More than 20 million Americans- one in nine adults- have chronic kidney disease, and most don't even know it.[1] Physicians are constantly searching for the most effective therapies to help people with end-stage renal disease (ESRD), which occurs when kidney disease has progressed and about 90% of... view more (2004-07-30)

Plant studies reveal how, where seeds store iron
Biologists have learned where and how some plant seeds store iron, a valuable discovery for scientists working to improve the iron content of plants.   view more (2006-11-07)

Dartmouth study contributes to research addressing malnutrition and iron deficiency
Dartmouth biologists are leading a research team that has learned where and how some plant seeds store iron, a valuable discovery for scientists working to improve the iron content of plants.   view more (2006-11-03)

More safety for cell phone batteries
Fraunhofer researchers will be presenting a novel lithium-ion battery at Hannover Messe on April 21 - 25. It is based on a polymer electrolyte, which is - unlike the liquid electrolyte in conventional lithium-ion batteries - not inflammable. A test set-up for redox flow batteries will also be on... view more (2008-04-14)

Iron banded worms drying out of blood could be linked to Parkinson's and Alzheimer's
Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood stream can, in certain circumstances, collapse into a state which grows long worm-like "fibrils" banded by... view more (2008-02-11)

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... view more (2008-08-06)

Iron-deficient infants have lower cognitive scores at 19, especially in lower socioeconomic levels
Costa Rican teens who were iron-deficient as infants continue to lag behind their peers in cognitive test scores, with a wider gap for children at lower socioeconomic levels.   view more (2006-11-07)

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)

Unexpected discovery about earth's core
The core of the earth doesn't look the way it was expected to. Scientists at the Royal Institute of Technology in Stockholm, Sweden , KTH, can now show that iron, under extremely high pressure, such as that found in the inner earth, takes on unexpected properties, and this can be of importance in... view more (2003-08-29)

A genetic cause for iron deficiency
The discovery of a gene for a rare form of inherited iron deficiency may provide clues to iron deficiency in the general population - particularly iron deficiency that doesn't respond to iron supplements - and suggests a new treatment approach.   view more (2008-04-14)

Increased hepcidin expression: A novel oncogenic signalling mechanism
Historically anaemia, which is associated with colorectal cancer, has been attributed to blood loss. Previous studies have elegantly shown that the anti-microbial peptide hepcidin can also induce anaemia as a consequence of infection and or inflammation.   view more (2008-03-19)

Europe's most common genetic disease is a liver disorder
Much less widely known than the dangerous consequences of iron deficiencies is the fact that too much iron can also cause problems. The exact origin of the genetic iron overload disorder hereditary hemochromatosis [HH] has remained elusive.   view more (2008-02-07)

NC State breakthrough results in super-hard nanocrystalline iron that can take the heat
Researchers at North Carolina State University have created a substance far stronger and harder than conventional iron, and which retains these properties under extremely high temperatures - opening the door to a wide variety of potential applications, such as engine components that are exposed to... view more (2008-05-28)

Scientists discover novel way to remove iron from ferritin
A new study led by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, Ph.D., is the first to suggest that a small protein or heptapeptide (seven amino acids wrapped into one unit) could be used to accelerate the removal of iron from ferritin.   view more (2007-11-05)

Iron supplements might harm infants who have enough
A new study suggests that extra iron for infants who don't need it might delay development -- results that fuel the debate over optimal iron supplement levels and could have huge implications for the baby formula and food industry.   view more (2008-05-05)

MRI study opens door to assessing, preventing dangerous brain iron levels
A magnetic resonance imaging (MRI) study at UCLA opens new doors to assessing and potentially preventing brain iron accumulation associated with risk of developing degenerative brain diseases such as Alzheimer's, Parkinson's and Dementia With Lewy Bodies.   view more (2006-03-27)
