Experimental Biology 2016 – Day 2

Today was a great day for trainees in comparative physiology! Here are some of the highlights from their sessions: Poster presentations: Alexis MacDonald et al., (Union College – Mentor Dr. Scott Kirkton) presented research showing that grasshopper skeletal muscles may use lactate for energy! Similarly, Dongying Wang et al., (Saint Louis University – Mentor Dr. Daniel Warren) also showed that skeletal muscle from painted turtles may use lactate. I guess it […]

Experimental Biology 2016 – Day 1

Today marked the official start of the Experimental Biology meeting for the American Physiological Society! The highest award the society offers a scientist is named in honor of Dr. Walter B Cannon, the physiologist (and 6th President of the society) who came up with the term ‘homeostasis’ in his 1930 book The Wisdom of the Body. This year’s award recipient is Dr. Amira Klip from the University of Toronto. In her […]

Heat stress in livestock

With the approach of summer, a timely study was published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on whether inflammation plays a role in heat stress-related complications in muscles. Heat stress is a major problem in the livestock industry. In the United States alone it is reportedly associated with a loss of approximately $158 billion annually in the swine industry. To cool off, swine seek shade and often mud baths […]

Pesticide confuses bees

A new study conducted by researchers at the University of Guelph found that the use of certain pesticides impacts wildflower pollination by bees. According to a quote by study author Nigel Raine, published in CBCNews, the use of neonicotinoid-type pesticides “modify the way in which information flows through the nervous system.” The research team found that bees gather pollen more frequently, but less efficiently, when exposed to the pesticide compared to […]
