A group of international collaborators has found a way to deliver Ebola prevention information to people in every part of Sierra Leone - safely, and at negligible cost. The team is rolling out animated videos narrated in local languages that can be viewed on cell phones, tablets, computers and other digital devices.
Thanks to a bit of genetic sleuthing, researchers now know the invasion history of the tropical fire ant (Solenopsis geminata), the first ant species known to travel the globe by sea.
The University of Illinois’ Institute for Genomic Biology has been renamed in honor of a microbiology professor who changed the course of science with his discovery of a third major branch of the tree of life. That professor, Carl R. Woese, died in late 2012.
Researchers report that trap-jaw ants recognize the unique odor of a fertile queen only if the queen also shares the workers’ own chemical cologne – a distinctive blend of dozens of smelly, waxy compounds that coat the ants’ bodies from head to tarsus.

A new study of muskrats and minks in central Illinois indicates that toxoplasmosis, a disease spread by cats, is moving rapidly through the landscape and contaminating local waterways.
