Black men are over-diagnosed with schizophrenia at least five times higher than any other group--a trend that dates back to the 1960s, according to new University of Michigan research.
Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy.
Using a technique that provides detailed images of nanoscale structures, researchers at the University of Michigan and Detroit's Henry Ford Hospital have discovered changes in the collagen component of bone that directly relate to bone health.
It's commonly known that plants interact with each other on an everyday basis: they shade each other out or take up nutrients from the soil before neighboring plants can get them. Now, researchers at the University of Michigan have learned that plants also respond to the past.
The most widely used human embryonic stem cell lines lack genetic diversity, a finding that raises social justice questions that must be addressed to ensure that all sectors of society benefit from stem cell advances, according to a University of Michigan research team.
Name all the venomous animals you can think of and you probably come up with snakes, spiders, bees, wasps and perhaps poisonous frogs. But catfish?
Proteins, which perform such vital roles in our bodies as building and maintaining tissues and regulating cellular processes, are a finicky lot. In order to work properly, they must be folded just so, yet many proteins readily collapse into useless tangles when exposed to temperatures just a few degrees above normal body temperature.
In a study that elevates the role of entropy in creating order, research led by the University of Michigan shows that certain pyramid shapes can spontaneously organize into complex quasicrystals.
With growing concerns about the effects of global warming on polar bears, it's increasingly important to understand how other environmental threats, such as mercury pollution, are affecting these magnificent Arctic animals.
A new study using solid-state NMR spectroscopy to analyze intact bone paves the way for atomic-level explorations of how disease and aging affect bone.
iPhones are being used as musical instruments in a new course at the University of Michigan.
We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines.
A new application for the Android smartphone shows users and software developers how much power their applications are consuming. PowerTutor was developed by doctoral students and professors at the University of Michigan.
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity.
A new center at the University of Michigan College of Engineering will enable fundamental research on low-temperature plasmas---ionized gases with vast potential for practical technological advancements in fields such as energy, lighting, microelectronics and medicine.
One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties.
Immunity to whooping cough lasts at least 30 years on average, much longer than previously thought, an analysis by researchers at the University of Michigan and the University of New Mexico shows.
Spend a little time people-watching at the beach and you're bound to notice differences in the amount, thickness and color of people's body hair. Then head to the zoo and compare people to chimps, our closest living relatives.
A University of Michigan survey released today shows widespread consumer interest in buying plug-in hybrid electric vehicles (PHEVs). But the cost of the cars is much more influential than environmental and other non-economic factors as a predictor of purchase probabilities.
Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins.
Standing out in a crowd is better than blending in, at least if you're a paper wasp in a colony where fights between nest-mates determine social status.
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock.
A new investigation of a fossilized tracksite in southern Africa shows how early dinosaurs made on-the-fly adjustments to their movements to cope with slippery and sloping terrain. Differences in how early dinosaurs made these adjustments provide insight into the later evolution of the group.
Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers. But although scientists have been investigating coal outbursts for more than 150 years, the precise mechanism is still unknown.
Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis.
University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications.
The Great Depression had a silver lining: During that hard time, U.S. life expectancy actually increased by 6.2 years, according to a University of Michigan study published in the current issue of the Proceedings of the National Academy of Sciences.
Older Americans have weathered the financial crisis relatively well, although many now expect to work longer than they did just a year ago, according to a University of Michigan study released on Capitol Hill today (Sept. 16).
Consumer spending will lag rather than lead the recovery from the current recession, according to University of Michigan economist Richard Curtin.
Cash for Clunkers may have run out of money, but certainly not gas.

As Congress and the White House explore ways to encourage Americans to conserve energy, a new study by the University of Michigan shows that the average individual energy demand for heating and cooling has decreased over the past 50 years.
The official poverty rate has never fallen below its 1973 level, but a University of Michigan researcher says this could change after the economy recovers from this recession if anti-poverty policies put in place by this year's stimulus package are made permanent.
With all the hype about beneficial antioxidants in everything from face cream to cereal bars, you'd think their targets---oxygen radicals---must be up to no good. It's true, the buildup of oxygen radicals and other reactive oxygen species (ROS) in cells contributes to aging and possibly to diseases such as cancer and Alzheimer's.
University of Michigan researchers have identified a gene that acts as a master switch to control obesity in mice. When the switch is turned off, even high-fat-diet mice remain thin.
