It’s colds and flu season, and as any parent knows, colds and flu spread like wildfire, especially through schools.

New research using human-networking theory may give a clearer picture of just how, exactly, infectious diseases such as the common cold, influenza, whooping cough and SARS can spread through a closed group of people, and even through populations at large.

With the help of 788 volunteers at a high school, Marcel Salathé, a biologist at Penn State University, developed a new technique to count the number of possible disease-spreading events that occur in a typical day.

This results are published in this week’s issue of the journal Proceedings of the National Academy of Sciences. (more…)

ANN ARBOR, Mich.— Several important findings come out of this year’s Monitoring the Future study, the 36th annual, national survey of American teens in a series that launched in 1975.

• Marijuana use, which had been rising among teens for the past two years, continues to rise again this year—a sharp contrast to the considerable decline of the preceding decade.

• Ecstasy use—which fell out of favor in the early 2000s as concerns about its dangers grew—appears to be making a comeback this year, following a considerable recent decline in the belief that its use is dangerous.

• Alcohol use—and, specifically, occasions of heavy drinking—continues its long-term decline among teens into 2010, reaching historically low levels. (more…)

Zen meditation has many health benefits, including a reduced sensitivity to pain. According to new research from the Université de Montréal, meditators do feel pain but they simply don’t dwell on it as much. These findings, published in the month’s issue of Pain, may have implications for chronic pain sufferers, such as those with arthritis, back pain or cancer. (more…)

COLUMBUS, Ohio — A spoonful of sugar may be enough to cool a hot temper, at least for a short time, according to new research.

A study found that people who drank a glass of lemonade sweetened with sugar acted less aggressively toward a stranger a few minutes later than did people who consumed lemonade with a sugar substitute.

Researchers believe it all has to do with the glucose, a simple sugar found in the bloodstream that provides energy for the brain. (more…)

Or does it? Fresh research from Oxford University seems to reveal that a low dose of aspirin taken over a substantial period of time produces promising results, indicating that the death rates of many types of cancer reduce greatly. In fact, the evidence presented is staggering and if true, would be a medical breakthrough of exponential proportions.

Let us be optimistic, for cancer is a disease which has cut across most families around the globe. Few of us have not lost a grandparent, parent, uncle or aunt to this disease, in some cases even brothers, or worse still, nephews or nieces…or worse still, sons or daughters, grandsons and daughters. Now it seems there is good news which does not involve chemo-therapy or radio-therapy, which create many success stories but also many victims. (more…)
