I am thrilled to see Dr. Stan Lindstedt’s review article published in the April 2015 issue of American Journal of Physiology: Regulatory, Integrative and Comparative Physiology from his 2013 August Krogh lectureship at the annual Experimental Biology conference. My original blog from the lecture can be found here. Dr. Lindstedt and co-author Dr. Niisa Nishikawa (Northern…

Ever wonder how flies navigate?

Dr. Vivek Jayaraman and colleagues at the Howard Hughes Medical Institute Janelia Research Campus discovered that the ellipsoid body located in the middle of a fly’s brain acts like a compass to help navigate flight even in darkness. By placing the flies into a small virtual reality arena and having the flies walk on a…

The opah (Lampris guttatus), otherwise known as a moonfish, lives in the deep sea where warm blood can be advantageous. According to a quote from Nicholas Wegner (NOAA) posted in Live Science, “Increased temperature speeds up physiological processes within the bod. As a result, the muscles can contract faster, the temporal resolution of the eye is…

Many species of ants are known for being rather clean by disposing of their dead outside of the nest and placing other wastes, like bits of food, in refuse chambers. Dr. Tomer J. Czaczkes (University of Regensburg) was surprised therefore to see “dark patches” build up in plaster nests that housed black garden ants (Lasius niger).…

Professor Wayne Vogl and colleagues at the University of British Columbia discovered that rorqual whales can gulp volumes of water that are bigger than their body. Nerves in the mouth and tongue make this amazing feat possible as they can actually stretch to twice their resting length without sustaining damage. Dr. Vogl was quote in CBC News…

Dr. Frank van Breukelen is an Associate Professor in the School of Life Sciences at the University of Nevada, Las Vegas. He was invited to tell us about a new research project in this laboratory about some really cool mammals called tenrecs. Here is the post: In a recent post, Dr. Dolittle mentioned a talk…

Sheep as models for diabetes

Insulin is a major hormone responsible for regulating blood sugar. Its main function is to lower sugar by increasing glucose uptake into muscle and fat cells. Insulin resistance is the hallmark of type 2 diabetes and occurs when tissues in the body are not able to respond to insulin resulting in sustained elevations in blood sugar,…

Hats off to all of the comparative physiologists who were recognized for their hard work and exciting research at the 2015 annual Comparative and Evolutionary Physiology Business meeting at the Experimental Biology conference earlier this month. I thought I would take a moment to recognize each awardee:              

Pretoria

I am listening Pretoria! Since there have been so many wonderful discussions led by students from the University of Pretoria over the last couple of years (refer to the comments), I thought I would recognize this wonderful place.  First of all, thank you for being so actively involved in the blog for your classes. I am…

Yesterday was the final day of the meeting with many late breaking poster presentations as well as this year’s Nobel Laureate lecture. This year’s American Physiological Society Nobel Prize in Physiology or Medicine Lecture was given by Dr. Robert J Lefkowitz from Howard Hughes Med. Inst. and  Duke Univ. Med. Ctr. He was awarded the Nobel…
