Marine parchment worms have an unusual response to threats. They release a sticky bioluminescent mucus that glows blue. This physiological response is unique because the bioluminescence is constant as opposed to appearing in flashes like other marine organisms. In order to produce sustained light, the mucus would have to contain a source of energy. What they found was that the slime contained an iron protein called ferritin. When the team […]

Today marked the final day of the 2019 Experimental Biology meeting in Orlando. As usual it was a great day for Physiology. Crupi et al., from the University of Messina and the Universita della Magna Grecia in Italy put up a poster presentation describing their research on how red blood cells respond to environmental toxins. Their research showed that isolated red blood cells from rabbits are more sensitive to venoms […]
Abigail Harms, an undergraduate student at Beloit College working with Dr. Kathryn Johnson, also presented her research today at the Experimental Biology 2019 conference examining the effects of obesity in horses. Just like humans and pets, horses are increasingly becoming obese. Her research is seeking ways to measure hormonal changes that occur with obesity in different breeds of horses.
So jealous. Research presented by Anthony Basile, graduate student in the laboratory of Dr. Karen Sweazea at Arizona State University, at Experimental Biology 2019 examined how mourning doves would respond to a diet high in saturated fats. He reported on how mice fed a similar diet develop pathological changes in hormones and metabolism, as would be expected. But, doves fed a similar diet did not seem to show any notable […]
I am pleased to showcase this year’s Comparative and Evolutionary Physiology Section (CEPS) award recipients at the Experimental Biology conference. Winners received their awards at the CEPS banquet last week. In earlier posts, I introduced this year’s Dr. Dolittle Travel awardee as well as Dr. Stanley Hillman, this year’s August Krogh Distinguished Lecturer. Here are the rest of award recipients: The New Investigator Award was earned by Dr. Allyson Hindle […]
Dr. Allyson Hindle from Massachusetts General Hospital in Boston, presented some interesting research on seals at the Experimental Biology conference this week in San Diego. Seals are known for being rather plump, which for humans often leads to inflammation and cardiovascular disease. In addition, seals undergo repeated bouts of hypoxia and reoxygenation during their dives, which is also known to promote inflammation and cardiovascular disease in humans. Her research team […]
Brine shrimp, Artemia franciscana, are neat little aquatic crustaceans. According to the University of Utah, these tiny creatures grow to about 1cm in length. They are a favorite meal choice of some migratory birds and they are often sold for use as food for fish destined for human consumption. Christopher Melendez, a graduate student in the lab of Dr. Casey Mueller at California State University San Marcos, presented his research on brine […]
