The first measurement of the mutation rate in koalas shows that their population began to collapse about 100 years ago – before humans arrived in Australia. A small eastern population survived and re-expanded.

Researchers from the Hebrew University of Jerusalem have documented for the first time the coordinated circular movement of thousands of terrestrial isopods of the species Armadillo sordidus. According to the study, the phenomenon is caused by artificial lighting at night, and not by breeding or magnetic attraction.
