    A smart pill for seniors?

    From Washington, D.C., at the Experimental Biology 2007 Conference

    Many people approaching retirement age find that memories fade and quick-wittedness flags. Scientists at the University of Massachusetts in Lowell have formulated what they call a "smart pill" to optimize brain health in such people. In pilot trials, its combination of dietary supplements boosted performance on simple...

    Alzheimer's marker yields blood test

    From Washington, D.C., at the Experimental Biology 2007 meeting

    Despite memory-test and brain-imaging advances in recent years, diagnosis of Alzheimer's disease remains a challenge. Usually, only the presence of clumps of the protein amyloid-beta in the brain at autopsy confirms that a person's dementia was Alzheimer's. A study in mice, however, suggests that a test for excess amyloid-...

    Gene dispensers

    From Chicago, at the American Chemical Society Meeting

    Researchers have developed a new means for transferring genes to treat diseases. The gene therapy method relies on a nanoscale architecture with many alternating layers of polyester and DNA. Once this material is inside the body, water degrades the polyester layer by layer, for a slow, controlled release of genetic material to...

    Keep on Going: Busy seniors live longer, more proof that it pays to stay active

    Elderly people who bustle around the house, spend much time on their feet, climb stairs, and hold down jobs might be buying themselves precious years of life.

    In a new study, researchers used a precise measure of calorie burning to assess activity. A total of 302 people, ages 70 to 82, completed questionnaires regarding their daily activities. All the volunteers got around without help...

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    Two drugs are equal in preventing breast cancer

    A commonly prescribed anti-osteoporosis drug works as well at preventing breast cancer in postmenopausal women as the sole drug currently prescribed for the task, a head-to-head trial shows.

    Scientists designed the study to compare oral doses of the osteoporosis drug raloxifene (Evista) with tamoxifen (Nolvadex) taken for 5 years. Roughly half of the nearly 20,000 women received...

    Tipsy Superfluids: Glimpsing off-kilter quantum clouds

    Physicists last year created an exotic state of matter previously unattainable in the laboratory but whose characteristics theorists have debated for more than 40 years. The latest probes of the new state suggest that the material—a cloud of ultracold atoms that's imbalanced with regard to a quantum property known as spin—behaves differently than most theorists had anticipated.

    Easy Answers: Quantum computer gives results without running

    Physicists have long known that quantum computers have the potential to race through calculations trillions of times as fast as ordinary computers do. Now, it seems that those machines may not have to calculate at all to deliver answers.

    That seemingly absurd possibility, which was advanced as a theory several years ago, has now received experimental verification. What's more, although...

    Fooling the Satiety Meter (with recipe)

    Want to lose weight without counting calories? A new study finds that the easiest strategy might be reducing a meal's energy density—calories per ounce of food. When volunteers were offered such density-diminished meals, they rated the fare as filling—and as palatable—as they had full-calorie versions of the same foods.

    Smaller portions also curbed how much someone...

    Inflammation-Fighting Fat

    Arthritis-ameliorating cheese, anyone? Asthma-moderating yogurt? How about a scoop of lupus-fighting ice cream? Although such foods don't yet exist, they might one day. Data from a new study finds that an unusual fatty acid, a type of dairy fat, can modulate the injurious, runaway inflammation that underlies these and many other diseases.

    The agent is a variant of the essential...
