Of all the questions we get about calcium, most come from women in their 40s and 50s who are rightfully worried about getting enough calcium to ward off osteoporosis later in life. But nobody can afford to skimp on calcium. Not women, not men and especially not children. Osteoporosis is a very expensive problem not just for the individuals who develop it, but for society at large.

A complication that afflicts as many as 20% of all cancer patients can be partly controlled by a new drug, researchers reported last week in the Archives of Internal Medicine. The condition, called hypercalcemia, causes high calcium levels in the bloodstream because of bone loss in severely ill cancer patients.

Columbia's astronauts took turns cycling around the world Wednesday and crawled into a vacuum bag that forced more blood into their legs. Payload commander M. Rhea Seddon made the ultimate sacrifice for the 14-day medical research mission--she exercised, and hard. After an hourlong session on a stationary cycle as the shuttle flew two-thirds of the way around Earth, the Tennessee-born physician informed Mission Control: "Us Southern girls don't like to perspire very much."

Researchers have identified a gene that may raise the risk of getting late-onset Alzheimer's disease by about 45% in people who inherit one copy of it. That form of the gene appears to hamper a brain cell's ability to take in calcium, according to a report Friday in the journal Cell.

A team of Harvard researchers may have discovered a new way to ward off the red, itchy rash caused by allergies to nickel. All it takes is a dab of topical cream, according to research published online Sunday in the journal Nature Nanotechnology. Thirty million to 45 million people -- more than 10% of the U.S. population -- are sensitive to nickel found in common objects including jewelry and coins, the paper reported. Among the sufferers: study lead author Jeffrey M. Karp of Harvard's Brigham and Women's Hospital in Boston, a nanoparticles specialist who sought a way to treat the irritating allergy.

Every so often, we take a candid look at the private dietary lives of people whose food choices need a makeover. Up this week: the kitchen and dining habits of 22-year-old Jessica Watson and her boyfriend, 31-year-old Todd Preboski. She's a vegan; he eats fish but no other animal-based foods. Such diets may conjure up images of fresh vegetables and fruits, nuts, tofu and whole grains. But a lack of time and planning have cornered the couple into relying too often on Taco Bell burritos, protein bars and potato chips.

Question: You have mentioned that water hardness can affect the natural pigments in food and result in color changes. Can you explain what is meant by water hardness? Answer: Hard water is simply water that contains natural salts. There are two types of hard water. In one, called "temporarily hard," the calcium, magnesium and iron bicarbonate are precipitated when water is boiled. Over a long period of time, deposits of these mineral salts build up.

Even a good night's sleep doesn't totally compensate for many weeks of sleep loss. And it's the late-night period when the accumulation of sleep loss may be most apparent. Researchers at Brigham and Women's Hospital examined the effect of weeks of insufficient sleep on performance. They scheduled nine healthy volunteers to live for three weeks on a schedule consisting of 43-hour periods in which they were awake for 33 of those hours. That equals about 5.6 hours of sleep for every 24 hours.

Women 65 and older who take calcium channel blockers--a widely used type of drug for high blood pressure and heart disease--are about twice as likely to develop breast cancer, researchers from the University of Washington reported in Wednesday's edition of the journal Cancer. But the risk of uncontrolled high blood pressure may outweigh any possible added risk of breast cancer, the National Institutes of Health said.

The high doses of Vitamin B-6 sometimes prescribed for premenstrual syndrome may be toxic, according to a University of Chicago scientist whose dietary guidelines mirror those recommended by other physicians debating the keys to women's nutritional health. Dr.
