We are excited to share the following interview with Dr. Lizzette Cambron, an NSF Graduate Fellow working in Dr. Kendra Greenlee’s laboratory at North Dakota State University. Dr. Cambron was scheduled to present her research at the 2020 Experimental Biology conference last month in a Comparative and Evolutionary Physiology session hosted by the American Physiological Society. As with many conferences, the meeting was cancelled due to Covid-19. She has agreed […]
Dr. Jose Pablo Vazquez-Medina (pictured at right), a comparative physiologist at the University of California – Berkeley, was scheduled to present several ongoing studies from his lab at the Experimental Biology conference last month. Dr. Vazquez-Medina is a member of the Comparative and Evolutionary Physiology section of the American Physiological Society. Although the conference was cancelled due to Covid-19, Dr. Vazquez-Medina has agreed to share his research with us. […]
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 […]
I am pretty sure most people would agree that dolphins are pretty smart. But did you know that they may develop similar neurological conditions as humans? I read an interesting article published in Drug Target Review exploring how dolphins that have washed up on beaches may help us understand neurological diseases like Alzheimer’s as well as responses to viral infections. For example, Dolphin morbillivirus (DMV) is a virus similar to […]
Researchers at Duke University in North Carolina have identified the first known case of coronavirus in a dog in the United States. Three human members of Winston’s family were known to have the virus and were participating in a study exploring treatments and vaccines. The research team discovered Winston had small amounts of the virus as they were collecting blood samples and nasal swabs weekly from members of his household […]
Phoenixin-20 is a small peptide that has been detected in mammals, birds, amphibians and fish. Studies have shown that it can modify reproductive processes in female mammals and fish. In addition, it has been shown in mammalian studies to act as a pain reducer and modulator of food intake. In a new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology, researchers explored whether phoenixin-20 has […]
Could you imagine eating a pile of chile peppers or spicy hot mustard and not feeling any pain? The ability to sense pain is physiologically quite important as it alerts us to potentially dangerous or poisonous chemicals. Many plants (stinging nettles, pungent bulbs, hot chilies) and animals (stinging ants, scorpions, snakes) produce noxious chemicals to protect themselves from predators. In turn, some predators have evolved resistance to these chemicals. An […]
