Why so many of us sleep

A special thank you to reader Dr. Barbara Goodman, Professor of Physiology at Sanford School of Medicine of the University of South Dakota who sent me a story from The Scientist about sleep in animals complete with footage of a dolphin that was seen apparently “sleeping” (video posted on YouTube): Why do animals sleep? This is a question with many…

Sleeping with one eye open

Researchers from La Trobe University and Max Planck Institute for Ornithology recorded young crocodiles and found that while the animals typically sleep with both eyes closed, in the morning hours they will sometimes open one eye periodically. If they placed another crocodile in the tank or stood nearby however, the animal would open one eye and look at…

Congratulations to Mallory Ballinger, a graduate student from the University of Minnesota-Duluth, who is the 2015 recipient of the Dr. Dolittle Travel Award! The purpose of this award is to recognize an outstanding graduate student or postdoctoral fellow involved in comparative and evolutionary research and to provide assistance for them to attend the annual American Physiological Society…

Sex differences in sleep apnea

I came across an interesting study published last month in American Journal of Physiology – Regulatory, Integrative and Comparative Physiology on obstructive sleep apnea (OSA), which is a disorder in which the upper airway is repeatedly obstructed during sleep resulting in bouts of intermittent hypoxia (low oxygen concentrations). I had no idea that OSA is…

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…
