In the wilds of New York City — or as wild as you can get so close to skyscrapers — scientists have found a new leopard frog species that for years biologists mistook for a more widespread variety of leopard frog.

While biologists regularly discover new species in remote rain forests, finding this one in the ponds and marshes of Staten Island, mainland New York and New Jersey — sometimes within view of the Statue of Liberty — is a big surprise, said the scientists from UCLA, Rutgers University, UC Davis, and The University of Alabama who worked together to make the unexpected discovery.

*A scarcity of women leads men to be impulsive, save less, and borrow more*

If you’re a male living in an area with fewer females than you would like, beware: You may be facing a double whammy.

According to new research from Vlad Griskevicius in the U’s Carlson School of Management, the perception that women are scarce in an environment leads men to be impulsive, borrow more, and save less.

First, mating insecurity; then, financial insecurity. Some guys can’t catch a break. (more…)

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…)

*Plant lineages with multiple copies of their genetic information face higher extinction rates than their relatives, researchers report in Science magazine.*

While duplication of hereditary information is a relatively rare event in animal evolution, it is common in plants. Potatoes, coffee, bananas, peanuts, tobacco, wheat, oats and strawberries, to name but a few, all carry multiple copies of their genetic material, in a condition called polyploidy.

In contrast, most animals including humans are diploid, meaning an individual carries only two copies of each chromosome, the carriers of genetic information, one from each parent. (more…)

Shade-coffee farms support native bees that help maintain genetic diversity in remnant tropical forests

ANN ARBOR, Mich. — Shade-grown coffee farms support native bees that help maintain the health of some of the world’s most biodiverse tropical regions, according to a study by a University of Michigan biologist and a colleague at the University of California, Berkeley.
