Several posters at EB 2022 in Philadelphia this month were focused on understanding the remarkable physiology of diving seals. Although we may think of the image below when we picture seals, they really are quite the athletes in water. Kaitlin Allen (a graduate student working in the laboratory of Dr. José Pablo Vázquez-Medina at the University of California Berkeley) presented her research on Northern elephant seals and how these animals […]
I learned a lot about how animals adapt to changing environmental oxygen levels in the Experimental Biology symposium on “Functional Integration across the Oxygen Cascade in the Face of Challenging Environments.” Here is what I learned… The first presenter, Dr. Lara do Amaral-Silva (postdoctoral fellow at the University of North Carolina at Greensboro working with Dr. Joseph (Joe) Santin), spoke about her research on adaptations in the bullfrog “super-brain” that […]
EB 2022 was a fantastic meeting (as usual) for comparative physiology. This meeting marked the last Experimental Biology conference as each society will be hosting their own meetings going forward. I soaked up as much as I could and will be sharing what I learned at the meeting over the coming weeks. “Predicting Species Physiological Responses to a Changing Climate” The first speaker in this symposium was Dr. Hollie Putnam […]
I sat through a very interesting session at this year’s Experimental Biology conference called, “The Power of Comparative Models for Accelerating Translational Healthspan Research: Underutilized Lab Animals, Companion Pets, Old World Monkeys, and Pumas.” While the title seems to capture the general idea of the symposium, I thought I would share a bit more information about the presenters and their exciting research. Dr. Karyn Hamilton from Colorado State University presented […]
Today we have a guest blog written by Elizabeth Evans (pictured above), a graduate student at the University of Dayton working in the laboratory of Dr. Carissa Krane. She presented her research on freeze tolerance today at the 2022 Experimental Biology conference in Philadelphia. She wrote the award-winning blog entry below which earned the 2022 Dr. Dolittle Travel Award to attend the conference. Congratulations Elizabeth!! Stranger than science fiction: treefrogs […]
Each year, the Comparative and Evolutionary Physiology section of the American Physiological Society presents their highest award, the August Krogh Distinguished Lecture, to a comparative physiologist who “has made major and meritorious contributions” to the field. Dr. August Krogh (1874-1949) was a physiologist who won the Nobel Prize in Physiology or Medicine in 1920. He was very interested in zoology and joined the University of Copenhagen as an Associate Professor […]
It is that time of the year again…I am so excited to be attending the upcoming Experimental Biology conference! This year’s program is packed with interesting Comparative Physiology sessions including the August Krogh Distinguished Lecture which will be given by Dr. Patricia Schulte from the University of British Columbia. Her lecture is titled, “Physiology in the Anthropocene: Insights from Intraspecific Variation in Response to Environmental Stressors.” Other seminars will include […]
I don’t know about you, but when I see an article claiming to be able to explain “The Biology of Beauty Sleep”, I simply have to read it. Clicking on the title brought me to a news article from the journal Nature Ecology & Evolution that featured a recent study examining the idea of how sleep impacts aging. The burning question of course is whether or not there is any […]
According to a study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, we have a lot in common with fruit flies when it comes to the layer of cells that line our airways. So much so, that researchers claim Drosophila melanogaster are important models for lung diseases such as chronic obstructive pulmonary disease (COPD). COPD is a debilitating disease that claimed the lives of over […]
Hibernating mammals are amazing! How in the world do they prevent blood clots when they not only reduce their body temperature but also their blood flow during hibernation? That question is precisely what a new study published in Physiological Genomics examined. Typically, cold temperatures are known to activate the process of blood clotting by stimulating platelets. Platelets are sticky cells without a nucleus that circulate in the blood. When […]
