Extreme Diet: The blood thirsty vampire bat

Just in time for Halloween: I came across a preprint in bioRxiv that identified 13 genes missing from vampire bats (Desmodus rotundus), but found in other bat species. Animals that drink blood, or sanguivores, have to deal with a diet that is high in protein but typically lower in fat and sugar. Many of the missing genes are thought to be related to their ability to drink blood and obtain […]

Now there’s an endurance athlete:

With the Beijing 2022 Olympics quickly approaching, I thought it would be fun to showcase some extreme animals. Take the Arctic tern (above), for example. These birds hold the record for longest migration. Terns are born during the summer in the Arctic circle and travel all the way to the Antarctic circle every year to spend the summer – a distance of ~30,000 km, talk about a marathon! For comparison, […]

Featuring: Ohio Physiological Society, Part 3

Granted the following topics are not comparative physiology research, I think they are certainly worth mentioning: Sayani Bhattacharjee, a graduate student at The University of Toledo, presented research on a novel way to overcome drug resistant prostate cancer, at least in cancer cells. A common treatment for prostate cancer is to block androgens. The problem with this treatment is that nearly all patients become resistant to the treatment. Fingers crossed […]

Featuring: Ohio Physiological Society, Part 2

Here are some additional highlights from the 35th annual Ohio Physiological Society conference… Elizabeth Evans (Graduate Student, University of Dayton), Dr. David Goldstein (Wright State University), and Dr. Carissa Krane (University of Dayton) presented research examining the effects of multiple freeze-thaw cycles on Cope’s Gray treefrogs (Dryophytes chrysoscelis). Yes, that’s right, I said freeze-thaw cycles. These freeze tolerant animals build up glycerol in their bodies to help survive seasonal conditions […]
