Anyone who has watched a lot of Saturday morning television likely has seen Taz, the voracious Tasmanian devil of Looney Tunes fame, a loud and voracious presence.

While Taz thrives in the cartoon, in the wild the species isn’t doing so well. About 20 years ago, a mysterious illness caused its population to dive.

Conservationists are scrambling to save the animals and educate the public about them. As part of that effort, Yindi and Jannali, two female Tasmanian devils, recently arrived at the St. Louis Zoo, where researchers are studying how they adjust to life in captivity.

Radioactive material has been discovered in a drainage area located in the northwest portion of the West Lake Landfill.

The federal Environmental Protection Agency ordered landfill owner Republic Services and the Cotter Corporation to collect sediment samples in March in response to heavy rains that occurred in late December and early January.

An international panel of scientists reported this week that glyphosate, the main ingredient used in Monsanto's weed killer Roundup is unlikely to cause cancer in humans.

Researchers have produced insulin-secreting cells from stem cells derived from the skin of patients with type 1 diabetes. The cells (blue), made from stem cells, can secrete insulin (green) in response to glucose.

After a meal, your blood sugar tends to rise. When it does, there are cells in your pancreas called beta cells that react by releasing insulin, which controls blood sugar.

People who have Type 1 diabetes have damaged beta cells and can't produce insulin. To manage the disease, they either have to inject insulin or wear a pump all day.

But new stem cell research at Washington University could lead to a breakthrough that helps their bodies produce the insulin they need.
