Researchers find new biomarker for fatal prostate cancer
New research findings out of Wake Forest University School of Medicine and the University of Wisconsin may help provide some direction for men diagnosed with prostate cancer about whether their cancer is likely to be life-threatening. view more (2009-02-13)
Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron. view more (2006-12-07)
Hot springs microbes hold key to dating sedimentary rocks, researchers say
Scientists studying microbial communities and the growth of sedimentary rock at Mammoth Hot Springs in Yellowstone National Park have made a surprising discovery about the geological record of life and the environment. view more (2008-01-23)
Boosting key milk nutrients may help lower type 2 diabetes risk
Most Americans fail to get the calcium and vitamin D they need, but this shortfall could be affecting more than their bones. view more (2007-07-11)
Vitamin D status appears more important than high calcium intake for maintaining calcium metabolism
Calcium intake levels of more than 800 mg/day may be unnecessary for maintaining calcium metabolism if vitamin D status is adequate. view more (2005-11-09)
Turning on hormone tap could aid osteoporosis fight
A potential new drug that 'opens the taps' for the release of useful hormones could stimulate new bone growth - and may eventually bring relief to osteoporosis sufferers. view more (2008-07-16)
Channels of cellular communication
A potential new channel of communication between different cellular compartments has been discovered by researchers at the University of Leeds. Dr Jim Deuchars` group show how the protein P2X7, which forms a channel known to mediate ion movements between cells and their external environment, may also work internally, facilitating communication... view more...

Young adults not drinking enough milk
Calcium and dairy products play major roles in health maintenance and the prevention of chronic disease. Because peak bone mass is not achieved until the third decade of life, it is particularly important for young adults to consume adequate amounts of calcium, protein and vitamin D found in dairy products to support health and prevent... view more...

Plants' management of nutrient suggests environmental remedies
A new understanding of how plants manage their internal calcium levels could potentially lead to genetically engineering plants to avoid damage from acid rain, which robs soil of much of its calcium. view more (2007-03-09)
Enzyme doesn't act alone in atrial fibrillation
An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. view more (2009-06-18)
A new understanding of why seizures occur with alcohol withdrawal
Epileptic seizures are the most dramatic and prominent aspect of the "alcohol withdrawal syndrome" that occurs when a person abruptly stops a long-term or chronic drinking habit. Researchers have shown that the flow of calcium ions into brain cells via voltage-gated calcium channels plays an important role in the generation of alcohol... view more... (2009-10-19)
Research casts doubt on controversial scientific theory
Scientists at the University of Sheffield have cast doubt on the validity of the controversial theory of biological cold fusion, the principle sometimes used to lend credence to the practice of selling silicon tablets to strengthen bones, on the assumption that the body will turn the silicon into calcium. view more (2003-05-07)
Rat kidneys and toad brains communicate in almost the same manner
Dutch researcher Niels Cornelisse used computer models to study the electrochemical communication between cells from rat kidneys and cells from the pituitary gland of a toad species. He found many similarities in the coupling of chemical and electrical signals in these completely different cells. view more (2004-05-07)
Diabetics on high-fiber diets might need extra calcium, report UT Southwestern researchers
The amount of calcium your body absorbs might depend, in part, on the amount of dietary fiber you consume. view more (2009-03-24)
Majority of osteoporosis patients not receiving calcium and vitamin D with treatment
New research published today at the annual meeting of the American Society for Bone and Mineral Research (ASBMR), Montréal, Canada, reveals that less than half (43%) of patients in Europe with osteoporosis are claiming to take both calcium and vitamin D supplementation with their osteoporosis treatment. view more (2008-09-15)
High calcium level in arteries may signal serious heart attack risk
Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology. view more (2009-07-28)
Calcium supplements may be little help for healthy kids
There's little question that most kids get too little calcium, but a new review of evidence casts doubt on the value of supplements and calcium-fortified foods to build stronger bones. view more (2006-04-19)
Calcium may be the key to understanding Alzheimer's disease
Researchers at the University of Pennsylvania School of Medicine have shown that mutations in two proteins associated with familial Alzheimer's disease disrupt the flow of calcium ions within neurons. The two proteins, called PS1 and PS2 (presenilin 1 and 2), interact with a calcium release channel in an intracellular cell compartment. view more (2008-07-21)
Scientists discover how coffee can reduce risk of pancreatitis
Scientists at the University of Liverpool have found how coffee can reduce the risk of alcohol-induced pancreatitis. view more (2006-03-14)
Calcium and vitamin D may not be the only protection against bone loss
Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2008-12-03)
