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…)

*The U’s active learning biology courses garner attention*

What if you could remove lead from a person’s blood with a bacterial protein that snags the toxic metal?

Or treat spinal cord injury by shutting off a gene that prevents nerve regrowth?

Ideas like these used to be the exclusive province of practicing biologists. But they are among 14 ideas conceived and presented recently by students in the University of Minnesota’s introductory biology course. (more…)

ANN ARBOR, Mich.— In these lean times, smart consumers refuse to pay a lot for throwaway items, but will shell out a little more for products that can be used again and again. The same is true of bacteria and other microbes, researchers at the University of Michigan have learned.
