In science news around the world, polio resurfaces in the Ukraine and in Mali, a report by the Global Forest Watch finds that trees are now disappearing fastest in the Mekong Delta, 16 U.S. agencies including Health and Human Services are moving to tighten rules intended to protect human research subjects, the authors of a study on grizzly bears and obesity retract the study due to falsified data, China's People's Liberation Army has trained monkeys to destroy bird nests near airfields, and more. Also, polluted waters and invasive sea stars are threatening the critically endangered spotted handfish, native to Tasmania, Australia.
