A study led by University of Calgary researchers reports that chronic wasting disease (CWD) prions can be detected in some animals that show no obvious symptoms, and that material from those animals was able to transmit infection in laboratory experiments. The authors say the findings do not indicate an immediate threat to people but add to evidence that CWD’s behavior across species warrants continued monitoring.

A new study warns that the growing koala population in South Australia's Mount Lofty Ranges could lead to widespread starvation if left unchecked. Researchers estimate the population makes up about 10 percent of Australia's total koalas and project further growth of 17 to 25 percent over the next 25 years without intervention. They recommend targeted fertility control as a humane solution.
