EAST LANSING, Mich. — The peak risk for misusing prescription pain relievers occurs in mid-adolescence, specifically about 16 years old and earlier than many experts thought, according to a new study by Michigan State University researchers.
The results, based on recent nationwide surveys of nearly 120,000 U.S. adolescents, suggest prevention programs may need to be introduced earlier, in childhood and early adolescence, said James C. Anthony of MSU’s Department of Epidemiology and Biostatistics. (more…)
COLUMBIA, Mo. — The sayings “variety is the spice of life” and “happiness isn’t getting what you want, but wanting what you get” seem to have a psychological basis, according to a new study by an MU psychologist who identified two keys to becoming happier and staying that way.
“Although the Declaration of Independence upholds the right to pursue happiness, that search can be a never-ending quest,” said Kennon Sheldon, professor of psychological sciences in the College of Arts and Sciences. “Previous research shows that an individual’s happiness can increase after major life changes, such as starting a new romantic relationship, but over time happiness tends to return to a previous level. Through our research, we developed a model to help people maintain higher levels of happiness derived from beneficial changes. The model consists of two major components: the need to keep having new and positive life-changing experiences and the need to keep appreciating what you already have and not want more too soon.” (more…)
COLUMBUS, Ohio – New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene.
This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient.
But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the body: They actually block some actions of vitamin A, which is critical to human vision, bone and skin health, metabolism and immune function. (more…)
If you throw a rubber balloon filled with water against a wall, it will spread out and deform on impact, while the same balloon filled with honey, which is more viscous, will deform much less. If the balloon’s elastic rubber was stiffer, an even smaller change in shape would be observed.
By simply analyzing how much a balloon changes shape upon hitting a wall, you can uncover information about its physical properties.
Although cells are not simple sacks of fluid, they also contain viscous and elastic properties related to the membranes that surround them; their internal structural elements, such as organelles; and the packed DNA arrangement in their nuclei. Because variations in these properties can provide information about cells’ state of activity and can be indicative of diseases such as cancer, they are important to measure. (more…)
EAST LANSING, Mich. — Researchers at Michigan State University have shown a prebiotic may help the body’s own natural killer cells fight bacterial infection and reduce inflammation, greatly decreasing the risk of colon cancer.
Prebiotics are fiber supplements that serve as food for the trillions of tiny bacteria living in the gut. When taken, they can stimulate the growth of the “good” bacteria. The evolution of prebiotic supplements (as well as probiotics, which are actual bacteria ingested into the system) provide new therapeutic targets for researchers and physicians. (more…)
In testing older patients’ blood vitamin D levels, there’s uncertainty about where the dividing line falls between enough and not enough. The threshold amount has become controversial as several scientific societies set different targets.(more…)
COLUMBUS, Ohio – Just 20 minutes of playing a violent shooting video game made players more accurate when firing a realistic gun at a mannequin – and more likely to aim for and hit the head, a new study found.(more…)
Former NBA player Herren recounts struggle with substance abuse
Former college basketball and NBA player Chris Herren spoke on the University of Delaware campus Thursday, April 19, about the struggle with substance abuse that eventually ended his career.
As a high school athlete, Herren played in the 1994 McDonald’s All-American game, was named player of the year from 1992-1994 by the Boston Globe and was the Gatorade New England Player of the Year from 1993-1994, before enrolling in Boston College to continue playing basketball. (more…)
