A long, controversial investigation of a polar bear scientist has ended with his government employer saying it does not look like he engaged in any scientific misconduct.
Charles Monnett is a wildlife researcher with the Bureau of Ocean Energy Management, part of the Department of the Interior. He and a colleague, Jeffrey Gleason, wrote an influential 2006 report describing apparently drowned polar bears floating in the Arctic, which they saw during a routine aerial survey of whales.

On the surface, the new coronavirus detected in the Middle East this month looks quite similar to SARS. It apparently causes severe respiratory problems, and can be lethal.
But with viruses, the devil is in their details — the genetic details.
Dutch virologists have just published the whole genome of the new coronavirus — all 30,118 letters of its code. And, the sequence reveals that the mystery virus is most closely related to coronaviruses that infect bats in Southeast Asia.

The Food and Drug Administration isn't sure, but Rita Desollar of Pekin, Ill., feels she knows what killed Heidi, her 7-year-old German shepherd. She feels it was the chicken jerky strips she bought at her local Walgreen's.
Desollar says on the Wednesday before Memorial Day, she gave two pieces of Waggin' Train jerky to Heidi as a treat. A few days later, Heidi was throwing up and "in a lot of distress," she says. By the time the holiday rolled around on Monday, Desollar says, Heidi was convulsing in her bed. She died that day, before Desollar could even take her to the vet.
Up next, the biology of raptors, moving from giant animals to the birds, we're going to talk about here in Boise. Just outside of town is the Snake River Birds of Prey National Conservation Area. And that park has one of the highest concentrations of nesting raptors in the world, more than 20 different birds of prey, including golden eagles, red-tailed hawks, screech owls.
When police find DNA at a crime scene, the amount and how it's handled are crucial components in solving a case. Greg Hampikian, Director of the Idaho Innocence Project, discusses the use and misuse of DNA analysis, and why he says all DNA evidence is not created equal.
Cheatgrass, an invasive weed, is choking out native sagebrush in the Great Basin--and setting the stage for hotter, more catastrophic fires there. Jen Pierce, an expert on ancient fires, and Mike Pellant, of the Great Basin Restoration Initiative, talk about how fires are reshaping landscapes in the American West.
Mammoths and saber-toothed cats may be the most famous beasts of the Ice Age. But they shared the prairie with horses and camels, too--both of which evolved in North America and crossed the ice bridge into Eurasia, before disappearing here. Matthew Kohn and Christopher Hill talk about the lesser-known fauna of the Ice Age.
NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.
The exposed rocks look like broken slabs of concrete sidewalk, about four inches thick, and are made of rounded bits of gravel in a sandy matrix. The rock has eroded a little bit, and some of the smooth pebbles — about the size of M&M candies — have fallen down into a little pile.
A future in which a discarded cell phone dissolves into a landfill, rather than living on for thousands of years as garbage, may not be that far off. Melissa Block talks with John A. Rogers, a 2009 MacArthur Fellow and professor of engineering at University of Illinois, about his research into "transient electronics."
