ANN ARBOR, Mich.— A new study from the University of Michigan and the University of Pittsburgh shows that even if a child isn’t crying, frowning or displaying other negative emotions on a consistent basis, another warning sign is when a child shows fewer positive displays, like hugging a parent or smiling and laughing.

“Surprisingly, it seems that it is low levels of happiness, as opposed to high levels of sadness, what may help explain why these kids too often develop depressive disorders,” said Nestor Lopez-Duran, an assistant professor of psychology at U-M and one of the study’s authors. (more…)

Preventing Diabetes Damage: Zinc’s Effects on a Kinky, two-faced Cohort

ANN ARBOR, Mich.—In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving.

Recent research at the University of Michigan offers new details about how zinc performs this “security guard” function. The findings appear in the July 8 issue of the Journal of Molecular Biology. (more…)

Winning margins in the Tour de France can be tight. In 2010 just 39 seconds separated the top two after more than 90 hours in the saddle. When every second counts, riders do all they can to gain competitive advantage, from aerodynamic carbon fibre bikes to the latest sports nutrition. (more…)

Death Rate From Heart Attack Higher in U.S. Territories Than on Mainland

There is a 17% greater risk of dying after a heart attack if you are treated in a hospital located in a U.S. territory-i.e. the U.S. Virgin Islands, Guam, Puerto Rico, American Samoa, and Northern Mariana Islands-rather than in a hospital in the mainland United States, according to new findings published in the Archives of Internal Medicine.

The study by Yale School of Medicine researchers shows that many U.S. citizens who call the U.S. territories home, are at a major healthcare disadvantage. (more…)

A new advance by UCLA biochemists has brought scientists one step closer to developing treatments that could delay the onset of Alzheimer’s disease and prevent the sexual transmission of HIV.

The researchers report that they have designed molecular inhibitors that target specific proteins associated with Alzheimer’s disease and HIV to prevent them from forming amyloid fibers, the elongated chains of interlocking proteins that play a key role in more than two dozen degenerative and often fatal diseases.

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…)
