Final 2019 Ohio Physiological Society Highlights

As you can probably tell from the prior posts, the 34th annual Ohio Physiological Society conference was a great meeting filled with exciting new developments in research. However, I would be remiss if I did not mention the outstanding students who received awards for their presentations at the conference.   Below are the 2019 Ohio Physiological Society Travel Award Winners (also pictured above). Each recipient was given $750 to attend […]

Adapting (or not) to increasing temperatures

Birds are not the only animals experiencing massive declines in populations. Rising temperatures and heat waves, in particular, have been blamed for killing humans and animals. In fact, a new review article published in Physiology mentioned that globally, heat is “a significant natural killer of humans, with the first decade of the 21st Century seeing a 23-fold increase in human casualties from heat waves compared with the 1990s.” If current predictions hold true, […]

New research on how treefrogs protect their cells during freezing

  Brian Stogsdill, Jim Frisbee and Dr. David Goldstein at Wright State University discussed their research at the 34th annual Ohio Physiological Society meeting on special water channels in the red blood cells of freeze-tolerant Cope’s gray treefrogs. These channels can shuttle both water and glycerol in and out of the cells to protect them from damage during freezing. Check out this video showing a treefrog waking up from a […]

On the path to understanding the effects of white-nose syndrome

Molly Simonis and colleagues from Wright State University and Ohio University presented interesting research at the 34th annual Ohio Physiological Society conference on their work looking at the physiological effects of exposure to white-nose syndrome. White-nose syndrome is caused by the fungus Pseudogymnoascus destructans and has been blamed for killing millions of bats in North America. This new study seeks to examine whether pregnant female Eptesicus fuscus bats, a species less susceptible to […]

Antarctic icefish do not tolerate rising temperatures

Antarctic finfishes may be facing rising ocean temperatures. This is of particular concern to icefishes, as they are not very tolerant of increasing temperatures. Prior studies have shown that this lack of tolerance may be due to an inability for their hearts to beat normally and actually collapse at higher temperatures. In a study presented at the 34th annual Ohio Physiological meeting at Wright State University today, researchers Evans et al., (working […]

Ohio talks about physiology and disease

Researchers from around the state of Ohio met today at the 34th annual Ohio Physiological Society meeting to discuss their research. Although many of the presentations were not on comparative physiology topics, I found some particularly interesting and thought I would share them with you anyway. Here goes: Dr. Katherine Vest and her research team (Kierra Ware, Yu Zhang, Thomas Whitlow) from the University of Cincinnati College of Medicine presented their research on […]
