    If each energy field pervading space is thought of as the surface of a pond, and waves and particles are the turbulence on that surface, then the new evidence strengthens the argument that a vibrant, hidden world lies beneath. For decades, the surface-level description of the subatomic world has been sufficient to make accurate calculations about most physical phenomena. But recently, a strange class of matter that defies description by known quantum mechanical methods has drawn physicists into the depths below... Of all the strange forms of matter, cuprates -- copper-containing metals that exhibit a property called high-temperature superconductivity...

And it is being done with the help of U.S. taxpayers through the municipal bond market."
  • The Milk Wars: Should Milk Be Taken Off the School-Lunch Menu?

    (Updated) The war on milk has shifted fronts. First it was sugar-laden chocolate milk, which parents and school administrators battled in recent years to remove from school-lunch menus. Now, it’s plain old moo that’s under fire. On Thursday, a national doctors group petitioned the U.S. government to remove milk as a required food group from the National School Lunch Program, the federally assisted program that has provided lunch to millions of public school kids since 1946. The doctors’ reasoning: milk doesn’t help protect kids’ bones. The promotion of milk to help build strong bones in kids is, “in effect, the...

    ( Summary) Magnesium balances calcium and its functions within the human body. It is believed that the adult human body contains approximately 1200 grams of calcium, with approximately 99% of it in the skeleton, and approximately 1% (about 12 grams) in extracellular fluids, intracellular structures, and cell membranes. This approximately 1% plays an essential role, in conjunction with magnesium, in the functions of nerve conduction, muscle contraction, blood clotting, and membrane permeability. It is believed that serum calcium concentration is maintained by several hormones, including estrogen and testosterone. It is known that dietary protein enhances calcium absorption, and dietary phosphorus...

    NEW YORK (Reuters Health) - A new analysis of earlier research finds that both higher vitamin D intake and higher blood levels of the vitamin's active form are linked to lower risk of colon and rectal cancers. In 18 studies that included more than 10,000 people, colon cancer risk was as much as 33 percent lower in subjects with the highest blood levels of vitamin D compared to those with the lowest levels, researchers report in the Journal of Clinical Oncology. Those with the highest intake of vitamin D through supplements and food had 12 percent lower risk than those...

    Excessive intake of calcium supplements may have adverse effect on health, notes a study.  Postmenopausal and pregnant women, transplant recipients, patients with bulimia (an eating disorder) and individuals on dialysis face the highest risk of developing the calcium-alkali syndrome.  The incidence of the calcium-alkali or the milk-alkali syndrome is growing in large parts, because of widespread use of over-the-counter calcium and vitamin D supplements.  Study authors Stanley Goldfarb and Ami Patel from the University of Pennsylvania School of Medicine (UPSM) recommend changing milk-alkali syndrome's name to calcium-alkali syndrome because it is now associated with a large calcium intake, not just...

    NEW YORK (Reuters Health) – Getting a bit more calcium in your diet could help you live longer, new research suggests. Swedish researchers found that men who consumed the most calcium in food were 25 percent less likely to die over the next decade than their peers who took in the least calcium from food. None of the men took calcium supplements. The findings are in line with previous research linking higher calcium intake with lower mortality in both men and women, the researchers point out in a report in the American Journal of Epidemiology.

    SNOWMASS, COLO. — Serious questions exist about the safety and efficacy of the popular practice of high-dose vitamin D supplementation across a broad swath of the population. One of these concerns is that not all of the extra calcium absorption promoted by boosting vitamin D is going into bone to prevent fractures. Some of it may actually be taken up by atherosclerotic plaque, increasing the risk of cardiovascular events, Dr. Lenore M. Buckley cautioned at a symposium sponsored by the American College of Rheumatology. This is of particular concern in patients with known coronary disease and for those at high...

  • New model suggests role of low vitamin D in cancer development

    In studying the preventive effects of vitamin D, researchers at the Moores Cancer Center at the University of California, San Diego, have proposed a new model of cancer development that hinges on a loss of cancer cells' ability to stick together. The model, dubbed DINOMIT, differs substantially from the current model of cancer development, which suggests genetic mutations as the earliest driving forces behind cancer. "The first event in cancer is loss of communication among cells due to, among other things, low vitamin D and calcium levels," said epidemiologist Cedric Garland, DrPH, professor of family and preventive medicine at the...

    Calcium linked to dementia Last Updated: 1:27am BST 14/05/2007 Calcium and vitamin D in dairy products may help to cause brain damage and dementia in older people, new research suggests. Scientists believe too much calcium can narrow blood vessels in the brain, leading to neural damage. The effect may be compounded by vitamin D, which regulates calcium retention and activity. Researchers made the discovery after scanning the brains of 79 men and 153 women aged up to 86. All had at least a number of brain lesions - areas of tissue damage. But those consuming the most calcium and vitamin...

    People taking powerful antacid drugs called proton pump inhibitors face an increased risk of hip fracture, University of Pennsylvania researchers report. Common proton pump inhibitors include Aciphex, Nexium, Prevacid, Prilosec and Protonix; they are often prescribed for stomach conditions such as gastroesophageal reflux disease (GERD). The report is published in the Dec. 27 issue of the Journal of the American Medical Association. "If you take acid-suppression medications on a chronic basis and you are 50 or older, your hip fracture risk is even higher than usual," said study author Dr.Yu-Xiao Yang, an assistant professor of medicine and epidemiology.

    The biggest study ever of calcium and vitamin D supplements for older women showed they offered only limited protection against broken bones, raising questions over what has been an article of faith among doctors and nutritionists. The supplements seemed to reduce the risk of broken hips in women over 60 and also helped those who took the supplements most regularly. But as to preventing bone fractures overall, vitamin D and calcium flunked in these healthy women. One of the researchers, Dr. Norman Lasser at New Jersey Medical School, said the study is "not as ringing an endorsement of calcium as...

    Anyone concerned about their bones is likely to make sure they have plenty of vitamin D, either by getting enough sunshine, eating fish, or taking supplements. Yet scientists know surprisingly little about how the compound works. A new study has finally shed some light on this process, showing how the vitamin takes part in a delicate balancing act between cells that tear down our bones and cells that rebuild them. Vitamin D is a familiar player in bone health. Without sufficient amounts of this hormone, our frames become frail with disorders such as osteoporosis or rickets. But vitamin D has...

The flimsy molecular pen may help map the brain's chemical circuitry and decipher the signals that control the beating heart. One way to study how cells function is to control the availability of a particular biomolecule by encapsulating it in a chemical box until a flash of light sets it free. Researchers have used this strategy to probe how cells...

A large study presented at a cancer conference Thursday found that men with higher levels vitamin D in their blood were half as likely to develop aggressive forms of the disease than those with lower amounts. Doctors are not ready to recommend the ``sunshine vitamin'' without more study, but many see little harm in getting the 15 minutes a day that the body needs to make enough of this nutrient. ``When you were little and...

    PERSONAL HEALTH Evolution is an excellent teacher when it comes to figuring out what and how much people should eat. For example, primates (including those with two legs and big brains) evolved on foods rich in potassium and very low in sodium. Early humans evolved to conserve sodium, which was hard to obtain, and to excrete excess potassium, abundant in many fruits and vegetables. But Western-style diets these days are the reverse of what those early humans consumed, rich in processed foods, loaded with sodium and relatively poor in potassium. Consequently, according to a report released this year by the...
