EAST LANSING, Mich. — Peer influence and low self-control appear to be the major factors fueling juvenile cybercrime such as computer hacking and online bullying, according to a new study led by a Michigan State University criminologist.

Thomas Holt, assistant professor of criminal justice, said the findings reinforce the need for parents to be more aware of their children’s friends and Internet activities.

“It’s important to know what your kids are doing when they’re online and who they are associating with both online and offline,” Holt said. (more…)

EAST LANSING, Mich. — Women’s bias against male strangers increases when women are fertile, suggesting prejudice may be partly fueled by genetics, according to a study by Michigan State University psychology researchers.

The study, funded by the National Science Foundation, appears online in Psychological Science, a major research journal.

“Our findings suggest that women’s prejudice, at least in part, may be a byproduct of their biology,” said Melissa McDonald, a doctoral student and lead author on the paper. (more…)

There’s More to Shopping Than Just Buying Stuff

EAST LANSING, Mich. — For women, shopping is more than just buying stuff. For some it can be therapeutic, for others a time to socialize, or for some a challenge to find the right product at the right price.

Michigan State University’s Patricia Huddleston is co-author of a new book, “Consumer Behavior: Women and Shopping,” which looks at the reasons why women go shopping, as well as provides a history of how shopping has evolved over the years. (more…)

Spurring Sweet Success

EAST LANSING, Mich. — Thanks to Michigan State University, a sweet partnership has helped resurrect Michigan’s $444 million sugar beet industry.

In 1996 the industry was in peril. Yields hit an all-time low due to pest, disease and production issues that greatly reduced crop health. Farmers were looking to get out of sugar beet farming and switch to more profitable crops. Industry representatives reached out to MSU to help solve the problem. (more…)

New Study Suggests Link Between Estrogen, Blood Pressure

EAST LANSING, Mich. — While recent studies have shown long-term exposure to estrogen can be a danger to women – overturning physicians’ long-held beliefs that the hormone was good for their patients’ hearts – the process by which estrogen induces high blood pressure was unclear.

In a new study, Michigan State University researchers found long-term estrogen exposure generates excessive levels of the compound superoxide, which causes stress in the body. The buildup of this compound occurs in an area of the brain that is crucial to regulating blood pressure, suggesting that the estrogen-induced buildup causes increased blood pressure. (more…)

Virtual Workout Partners Spur Better Results

EAST LANSING, Mich. — Can’t find anyone to exercise with? Don’t despair: New research from Michigan State University reveals working out with a virtual partner improves motivation during exercise.

The study led by Deborah Feltz, chairperson of MSU’s Department of Kinesiology, is the first to investigate the Kohler effect on motivation in health video games; that phenomenon explains why inferior team members perform better in a group than they would by themselves. (more…)

Solar Cells more Efficient than Photosynthesis – for Now

EAST LANSING, Mich. — In a head-to-head battle of harvesting the sun’s energy, solar cells beat plants, according to a new paper in Science. But scientists think they can even up the playing field, says Michigan State University researcher David Kramer.

Plants are less efficient at capturing the energy in sunlight than solar cells mostly because they have too much evolutionary baggage. Plants have to power a living thing, whereas solar cells only have to send electricity down a wire. This is a big difference because if photosynthesis makes a mistake, it makes toxic byproducts that kill the organism. Photosynthesis has to be conservative to avoid killing the organisms it powers.

Research Maps Out Trade-offs Between Deer and Timber

EAST LANSING, Mich. — In a sweeping study of a huge swath of Michigan’s Upper Peninsula, Michigan State University researchers document that in many places the sugar maple saplings that should be thriving following harvesting are instead ending up as a deer buffet. This means the hardwood forests are not regenerating.

Since the 1950s, sustainability in northern hardwood forests was achieved by chopping down trees in small clumps to naturally make room for new ones to spring up. Early experiments with single-tree and group selection logging found that desirable species like sugar maples did a great job of regenerating in the sunny, rain-drenched harvest gaps – theoretically eliminating the need to replant.
