Faced With Job Loss? Perception is Everything

ANN ARBOR, Mich.— When faced with job loss, people who consider themselves poor may limit employment prospects by believing they have a smaller social network than they actually do, says a University of Michigan business professor.

“Social networks help explain people’s outcomes in the labor market by determining how people seek help,” said Ned Smith, assistant professor of strategy at the Michigan Ross School of Business. “Network contacts offer two primary resources for job search—information, which provides job seekers with knowledge about where to find employment, and influence, whereby network contacts affect people’s success in actually securing employment by swaying the hiring process.” (more…)

It Takes Two to Tango: Pairs of Entwined Proteins Handle The Stress

ANN ARBOR, Mich.— Imagine two tango dancers sweeping across the dance floor and suddenly encountering a slick spot. To avoid a slip or even a nasty tumble, the pair must work together to support one another and glide safely through the stressful moment.

In a similar way, a certain type of helper protein called a stress-specific molecular chaperone prevents its client proteins from collapsing during stressful situations by uncoiling a long, supportive arm that wraps around them, a University of Michigan-led research team has shown. (more…)

When Continents Collide: A New Twist To a 50 Million-Year-Old Tale

ANN ARBOR, Mich.— Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau.

India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end and why. She conducted a study that led to surprising findings that could add a new wrinkle to the well-established theory of plate tectonics – the dominant, unifying theory of geology. (more…)

Protecting People From Deadly Floods, Quakes in The Philippines

ANN ARBOR, Mich.— Typhoons thrash the Philippines every year, causing flash flooding and mudslides that often kill hundreds of people in the Southeast Asian nation. Many blame the death and destruction on the wrath of nature. But Gavin Shatkin has a different view.

“Disasters are not natural,” said Shatkin, an associate professor of urban planning at the University of Michigan. “They happen because of social structures.” (more…)

Fastest Wind From Stellar Mass Black Hole Discovered

ANN ARBOR, Mich.— The fastest wind ever discovered blowing off a disk around a stellar-mass black hole has been observed by a team of astronomers that includes a University of Michigan doctoral student.

Using NASA’s Chandra X-ray Observatory, an orbiting telescope, they clocked the record-breaking super wind at about 20 million mph, or about 3 percent of the speed of light. This is nearly 10 times faster than astronomers had previously observed from a stellar-mass black hole. (more…)

Pregnant Primates Miscarry When New Male Enters Group

ANN ARBOR, Mich.— Pregnant female geladas show an unusually high rate of miscarriage the day after the dominant male in their group is replaced by a new male, a new University of Michigan study indicates.

The “Bruce effect” – in which pregnant females spontaneously miscarry after being exposed to an unfamiliar male – has been found repeatedly in laboratory rodents. However, no conclusive evidence for this effect had ever been demonstrated in a wild population prior to this study. Geladas are Old World monkeys that are close relatives of baboons. (more…)

Genes Linked To Cancer Could Be Easier To Detect With Liquid Lasers

ANN ARBOR, Mich.— Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.

Their results are published in the current edition of the German journal Angewandte Chemie. (more…)

A Galactic Magnetic Field in A Lab Bolsters Astrophysical Theory

ANN ARBOR, Mich.— Why is the universe magnetized? It’s a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.

The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. (more…)
