Should professors engage in public and political debate?

ANN ARBOR — Andrew Hoffman, a University of Michigan professor who teaches and researches business sustainability at the U-M Stephen M. Ross School of Business, frequently wades into the controversial debate over climate change.

Knowing how and when to do so is something he has figured out through trial and error. Why more academics don’t speak up and what the ground rules should be for those who do is a little hazy. (more…)

Architecture of signaling proteins enhances knowledge of key receptors

ANN ARBOR — A team of scientists from the University of Michigan, Duke Medicine and Stanford University has determined the underlying architecture of a cellular signaling complex involved in the body’s response to stimuli such as light and pain.

This complex, consisting of a human cell surface receptor and its regulatory protein, reveals a two-step mechanism that has been hypothesized previously but not directly documented. (more…)

Evolution and venomous snakes: Diet distinguishes look-alikes on two continents

ANN ARBOR — On opposite sides of the globe over millions of years, the snakes of North America and Australia independently evolved similar body types that helped them move and capture prey more efficiently.

Snakes on both continents include stout-bodied, highly camouflaged ambush predators, such as rattlesnakes in North America and death adders in Australia. There are slender, fast-moving foragers on both continents, as well as small burrowing snakes. (more…)

A new way to make laser-like beams using 250x less power

ANN ARBOR — With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam.

They have made what’s believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero. (more…)

Growing inequalities make science more of a ‘winner takes all’ field

ANN ARBOR — As new research documents growing inequalities in health and wealth, the gap between “haves” and “have-nots” is growing in the field of scientific research itself, says University of Michigan sociologist Yu Xie.

“It’s surprising that more attention has not been paid to the large, changing inequalities in the world of scientific research, given the preoccupation with rising social and economic inequality in many countries,” said Xie, research professor at the U-M Institute for Social Research and professor of sociology, statistics and public policy.
