A prestigious scientific journal Wednesday took the unusual step of retracting some high-profile research that had generated international excitement about stem cell research.
The British scientific journal Nature retracted two papers published in January by scientists at the Riken research institute in Japan and at Harvard Medical School that claimed that they could create stem cells simply by dipping skin and blood cells into acid.
Blame it on the animal crackers. A plastic jar of the treats was too enticing for a young bear in New Jersey, which got its head irretrievably wedged in the container. When people approached it to help, the 28-pound bear cub got scared — and climbed 40 feet up a tree, where it became stuck.
The incident happened in Ringwood, a small New Jersey town that's situated among forests and parkland. Workers from the state Environmental Protection Department and other local agencies got the cub safely back down and cut the jar off its head — but not before taking a photo of its plight.
