Mice in the early stage of Alzheimer’s disease had some of their brain abnormalities reversed and their declining mental function restored when they were given low doses of a rarely used cancer drug. The drug, bexarotene, stimulated the removal of ­beta-amyloid, a substance whose accumulation in the brain appears to be the main cause of Alzheimer’s dementia. After treatment, the animals fared better in tests of memory and social behavior, according to a study published online Thursday by the journal Science. Read full article > >

When it comes to warding off premature death, how fit you are may be more important than how much you weigh. Research published Monday afternoon in Circulation, the Journal of the American Heart Association followed 14,358 middle-aged men (median age 44) over 11.4 years. Those who became more fit (according to measurements of aerobic intensity on a treadmill) or maintained fitness were at lower overall risk of death and also of dying from cardiovascular disease during the followup period.

Explicit “sexting” by kids may be far less prevalent than previously thought, and police intervention may also be less common according to two new reports published online today in the journal Pediatrics . The first survey finds that only about 1 percent of children 17 and younger have texted explicitly pornographic images. That’s a significantly lower percentage than previous studies have found, such as one that reported as many as 20 percent of kids participate in sexting . Read full article > >

Too much time spent sitting increases the risk of developing cancer, even for those who exercise regularly. That’s according to research presented Thursday morning at the American Institute for Cancer Research’s annual conference . The AICR presented data suggesting that about 100,000 new cases of breast cancer and colon cancer per year can be associated with physical inactivity. One study presented at the conference and published in October in the journal Cancer Prevention Research found that among post-menopausal women, taking frequent breaks from sitting was associated with smaller waist circumference and lower levels of C-reactive proteins, both biomarkers associated with elevated risk of some cancers. In an analysis of data for 4,757 participants in the National Health and Nutrition Examination Survey (NHANES) published in the European Heart Journal, even short periods of light activity — frequently standing up and walking for as little as a minute at time — reduced risk for such biomarkers as large waist circumference, elevated triglyceride levels and increased insulin resistance, which are linked to heightened cardiovascular disease but might also boost cancer risk.

HAGERSTOWN, Md. — Three scientists say they’re preparing a research paper questioning the government’s conclusion that an Army microbiologist at Fort Detrick in Frederick was the sole perpetrator of the 2001 anthrax attacks. Louisiana State University epidemiologist Martin Hugh-Jones said Monday that the paper is scheduled for publication next month in the Journal of Bioterrorism & Biodefense. Read full article > >

If you wonder what kinds of beverages you should allow your kids to drink, a report published Monday morning in the journal Pediatrics makes things crystal clear: That’s just one of many useful nuggets of information from the report’s informative review of sports and energy drinks, the differences between the two and the way they should and, more important, shouldn’t be consumed. In short, the report, by the American Academy of Pediatrics Committee on Nutrition and the Council on Sports Medicine and Fitness, notes that sports drinks and energy drinks are not interchangeable and that most kids shouldn’t drink either of them, ever.

Somewhere in my journal, “2011″ is written big and bold across an entire page. The same thing is hanging on a piece of paper on the wall of my room in New Jersey. I wrote them two years ago, signifying my goal — to represent my country in the FIFA Women’s World Cup in Germany. Also in my journal is written “2008,” the year of the last Olympics. I did not achieve that goal.
