Life on Terra Firma Began with an Invasion

Scientists are now confident animal life on solid ground started with a few short bursts of marine creatures making the leap from the oceans. New research at the University of Portsmouth also paints a clear picture of how animals rapidly spread out and changed once they made the leap.

High Levels of PFOA Found in Mid-Ohio River Valley Residents From 1991 to 2013

New research from the University of Cincinnati (UC) reveals that residents of the Mid-Ohio River Valley had higher than normal levels of perfluorooctanoic acid (PFOA) based on blood samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver. This is the first study of PFOA serum concentrations in U.S. residents in the 1990s.

Changing natural electrical signaling in non-neural cells improves innate immune response to bacterial infections and injury. Tadpoles that received therapeutics, including those used in humans for other purposes, which depolarized their cells had higher survival rates when infected with E. coli than controls. The research has applications for treatment of emerging diseases and traumatic injury in humans.
