Dancing frogs

Scientists in the jungles of southern India have discovered 14 new species of “dancing frogs” many of which are unfortunately already endangered. DNA analyses have shown that these new species are members of an ancient genus that has been around since the time of the dinosaurs, Micrixalus. There are now 24 known species of dancing…

Here is a neat video that I watched at the David Bruce Undergraduate Poster session at the Experimental Biology conference last week. It describes the amazing physiology of the avian lung and was created by an undergraduate student researcher, Peter Luu for the Physiology Video Contest sponsored by the American Physiological Society. This video won…

Additional highlights from the Comparative Physiology posters presented at the 2014 Experimental Biology conference in San Diego, CA: TA White, G Evans, GC Verzosa, T Pirtskhalava, T Tchkonia, JD Miller, JL Kirkland, and NK LeBrasseur. “Aging and cellular senescence and disease: The influence of diet and exercise” Not surprisingly, mice consuming a fast food diet…

Experimental Biology Day 4

Day 4 of the meeting turned out to be pretty exciting for a comparative physiologist as well. The first session that I went to was called “RNASEQ approaches to understanding extreme physiological adaptations.” Considering the Comparative and Evolutionary Physiology section business and dinner meeting was the night before, I was impressed at my ability to…

Day 3 of the Experimental Biology meeting was arguably one of the most exciting for comparative physiology. Here are the highlights from Monday: Morning Seminars: Birgitte McDonald from Aarhus University, Denmark presented, “Deep-diving sea lions exhibit extreme bradycardia in long-duration dives.” Birgitte and Dr. Paul Ponganis measured the heart rate of California sea lions (Z.…

Check out the world’s fastest animal (relative to its size): This research was featured at this year’s Experimental Biology conference!

Experimental Biology Day 2

Another exciting day at the Experimental Biology meeting for physiologists! Although I am a bit nervous about the session on the negative effects of sleep deprivation, “Sleepless in San Diego: Is Sleep Deprivation the New Silent Killer?” Hmmm, maybe I should have gone to bed a bit earlier last night… Dr. Karen Matthews (Univ of…

Experimental Biology Day 1

The meeting is off to a good start. I attended a session sponsored by the American Physiological Society on Animal Models of hypertension caused by the nervous system, or neurogenic hypertension. While their definition of comparative really only meant rats, dogs and humans, I found it very interesting nonetheless. The speaker, Dr. Olson from the…

Heading to the airport

I am very excited about the Experimental Biology conference that starts this weekend. I have my bags packed, my poster printed and I am heading to the airport to catch my plane. I can’t wait to learn about all of the exciting physiology (especially comparative physiology) research. I will be sure to keep you up-to-date…

Cats beware…

The FDA has issued a warning that Easter lilies are toxic to cats. According to veterinarian Dr. Melanie McLean at the US Food and Drug Administration ingestion of even a small portion of the leaves, pollen or flowers of the plant are very poisonous to cats. Initial complications include vomiting but then may lead to…
