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…)
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…)
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…)
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…)
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.

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.

EAST LANSING, Mich. — Latinos still tend to favor Democratic candidates, although Latinos who identify themselves as Republicans are more likely to vote in the Nov. 2 midterm elections, a Michigan State University scholar says.
According to the 2010 National Survey of Latinos, 44 percent of Latino Republicans said they had given the election a lot of thought, compared to 28 percent of Latino Democrats.
“While Latinos in general are much more likely to support the Democratic Party, when it comes down to it, Latino Republicans may be more likely to show up at the polls on Tuesday,” said Rubén Martinez, director of MSU’s Julian Samora Research Institute.
According to the national survey data, Latinos generally favor Democrats, with nearly 66 percent of Latino registered voters saying they plan to support the Democratic candidate in their congressional district. In contrast, only 22 percent said they plan to support the Republican candidate in their district. (more…)
