Highways and urban sprawl have left the cats' territories increasingly isolated from each other, a study shows

Archaeologists have determined that artwork found in limestone caves on the Indonesian island of Sulawesi is far older than previously thought.

It’s Octopus Awareness Day, and although we at Octopus Chronicles treat every day as if it were a celebratory day for the cephalopod, today it gets extra special treatment.

The 2014 Nobel Prize in Physiology or Medicine goes to John O'Keefe, May-Britt Moser and Edvard I. Moser for their discoveries of cells that constitute a positioning system in the brain—an inner GPS. The winning work is explained by Karolinska Institute faculty and Nobel Committee members Göran Hansson, Ole Kiehn, Hans Forssberg and Juleen Zierath
 

The biting midge Culicoides (Trithecoides) anophelis Edwards is a predator of engorged mosquitoes, which was first described by Edwards in 1922 [1].At least 19 mosquito species in the genera Anopheles, Culex, Aedes and Armigeres have been documented as hosts of C.
