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)

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere
Scientists have discovered a bacterial "switch gene" in two groups of microscopic plankton common in the oceans. The gene helps determine whether certain marine plankton convert a sulfur compound to one that rises into the atmosphere, where it can affect the earth's temperature, or remain... view more (2006-10-30)

Iron 'snow' helps maintain Mercury's magnetic field, scientists say
New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground.   view more (2008-05-08)

Researchers probe a DNA repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA. Enzymes called helicases play a key role in human health, according to Maria Spies, a University of Illinois biochemistry professor.   view more (2008-02-19)

New approach removes sulfur from military-grade fuel; Syngas powers the process
The military needs to get the sulfur out of its fuel, in order to use the fuel to produce hydrogen for fuel cell use in the field.   view more (2006-03-29)

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... view more (2003-03-07)

Chemists forge a new form of iron
An international team of chemists has discovered a new and unexpected form of iron, a finding that adds to the fundamental understanding of an element that is among the most abundant on Earth and that, in nature, is an essential catalyst for life.   view more (2006-06-02)

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)

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)

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... view more (2005-02-10)

Better measurements reveal seasonal changes in sulfur
Researchers from the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have developed a new and improved technique for the simultaneous measurement of sulfur isotopic ratios and concentrations of atmospheric sulfate using snow samples from Greenland and... view more (2005-10-10)

Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way.   view more (2008-03-28)

UGA scientists discover bacterial 'switch gene' that regulates oceans' sulfur emissions into the air
The number of plankton in the seas is almost beyond comprehension. A single teaspoonful of ocean water holds several million of these microscopic drifters, and in recent years, scientists have discovered plankton are involved with everything from the health of the water to global warming.   view more (2006-10-27)

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)

Removal of Nitrogen from Motor Exhaust Sulfur-resistant process
Who doesn’t want to save fuel? Vehicles with lean-burning engines are therefore gaining ground. These engines work with excess air and can run on noticeably less fuel. This spares thewallet of the frequent driver, and also releases less carbon dioxide into the atmosphere. However,these... view more (2000-08-16)

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen.   view more (2006-08-24)

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)

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)

Iraq war service: A risk factor for bronchiolitis?
A large group of soldiers returning from Iraq have been diagnosed with bronchiolitis, a disease affecting the small airways of the lung, according to Vanderbilt University Medical Center physicians who will present their findings at the American Thoracic Society's 2008 International Conference in... view more (2008-05-21)

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)

Early environmental exposure may accelerate age-related neurodegeneration
Exposure to iron during the first weeks of life in combination with exposure later in life to a common herbicide may contribute to the subsequent degeneration of brain cells associated with the onset of Parkinson's disease (PD), according to a new study in mice.   view more (2007-06-28)

Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere.   view more (2008-01-17)

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)
