A new study tracks how cockroaches spread around the globe to become the survival experts we know today. Researchers analyzed the genes of over 280 cockroaches across 17 countries and confirmed that the German cockroach, found around the world, actually originated in southeast Asia over 2,000 years ago. The cockroaches then may have hitchhiked in…

Post-doctoral researcher Joe Edwards and graduate student Sarah Love, both in the University of Tennessee at Knoxville’s Department of Ecology and Evolutionary Biology, have published published findings this spring that can save fellow researchers a lot of time and energy when storing soil samples for later study of their microbial content. Post-doctoral researcher Joe Edwards and…
Researchers analyzed water quantity and quality data from domestic agricultural reservoirs to shed light on the hydrological impacts of a severe drought on degrading the water quality.

Drinking tea can have several health benefits. There is seemingly a brew for everything from sleep to inflammation to digestion. In 18th century England, however, drinking tea may have saved a person’s life, and it likely had very little to do with leaves and herbs. Drinking tea can have several health benefits. There is seemingly a…
