ANN ARBOR — Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.
The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer’s disease and other neurodegenerative conditions. (more…)
ANN ARBOR — An increasing number of Americans indicate that there is evidence of global warming, with 67 percent now expressing a belief that the planet has warmed over the past four decades, according to a University of Michigan survey.
It marks the highest level of belief in global warming since a 72 percent-measure in 2008 and is up from 52 percent in spring 2010.
The results come from the National Surveys on Energy and Environment, a joint effort of the Center for Local, State, and Urban Policy at U-M’s Ford School of Public Policy and the Muhlenberg Institute of Public Opinion at Muhlenberg College in Allentown, Pa. (more…)
ANN ARBOR — Sea surface temperatures in the tropical South Atlantic Ocean can be used to accurately forecast, by up to four months, malaria epidemics thousands of miles away in northwestern India, a University of Michigan theoretical ecologist and her colleagues have found.
Colder-than-normal July sea surface temperatures in the tropical South Atlantic are linked to both increased monsoon rainfall and malaria epidemics in the arid and semi-arid regions of northwest India, including the vast Thar desert, according to Mercedes Pascual and her colleagues, who summarize their findings in a paper published online March 3 in the journal Nature Climate Change.

ANN ARBOR — Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.
Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. (more…)
ANN ARBOR — Young adults in Generation X are as likely to connect with friends, family and co-workers online as they are in person, according to a University of Michigan study.
In a typical month, adults in their late 30s report that they engaged in about 75 face-to-face contacts or conversations, compared to about 74 electronic contracts through personal emails or social media. (more…)
ANN ARBOR — In a study that gives astronomers new insights into how planets form, research led by the University of Michigan has enabled a dramatically more precise measurement of the amount of dust and gas in the planet-forming disk around a young star.
The findings speak, in a way, to a fundamental question: “Why are we here?” (more…)
ANN ARBOR — Michigan health officials are using HIV surveillance technologies to assist in enforcing a “health threat” law that makes it illegal for HIV-positive people to have sex without disclosing their status.
A new University of Michigan study reveals that health officials employ the state’s names reporting database, alongside partner services referrals, for law enforcement purposes. However, this is bad social policy for a variety of reasons, says Trevor Hoppe, the study’s author and a doctoral candidate in sociology and women’s studies. (more…)
ANN ARBOR — Gangs now occupy two spaces: the streets and the Internet.
A new University of Michigan study reports that, in addition to carrying guns, gang members have armed themselves with social media sites such as Twitter, Facebook and YouTube to incite dares, trade insults or make threats that may result in homicide or other crimes.
Researchers have described this new interaction as “Internet banging.” They examine several factors, including the role of hip-hop music in this phenomenon and urban masculinity’s influence on social media behavior. (more…)
