Credit: iStock Menopause is a stage in a person’s life when their menstrual cycle stops. The average age in the U.S. is 52. During this time, the ovaries stop producing estrogen and progesterone—hormones that regulate the reproductive cycle and support pregnancy—marking the end of reproductive function. After going without a period for 12 consecutive months, … Continue reading Spotlight On: Menopause
Credit: iStock We see unique body sizes and shapes, faces and personalities every day. So, it should not come as a surprise that no two people are exactly alike—not even identical twins. Aside from the obvious differences in people’s outward appearance, there are many differences in people’s physiology as well. Mary-Ellen Harper, PhD, from the … Continue reading When It Comes to Losing Weight, One Size Does Not Fit All

She presented her work last month at Experimental Biology. Dr. Dolittle, the American Physiological Society’s comparative physiology blogger, chatted with Pearson and her mentor, Michael Tift, PhD, an assistant professor at UNCW. … Continue reading Experimental Biology 2021: Q&A with Dr. Michael Tift and Anna Pearson
Credit: iStock Scientists who study physiology and other biomedical research fields—including anatomy, biochemistry, pathology and pharmacology—network, collaborate and communicate about the latest research at the APS annual meeting at Experimental Biology (EB). This year’s virtual EB featured studies ranging from mitochondrial function and tissue repair to the effects of capsaicin on exercise performance. Read on to learn more … Continue reading New Science on Deep Heat Creams, Herbicides and Daytime Sleepiness Presented at Experimental Biology 2021
Credit: iStock As we get older, our cardiovascular system changes dramatically. Specifically, our blood vessels become stiffer and lose some of their ability to relax. This is known as endothelial dysfunction. Scientists debate and propose many theories about the specific causes of endothelial dysfunction with aging. Recently, telomeres have become a hot research topic. Telomeres … Continue reading Small but Mighty: How Telomeres Could Control Vascular Aging
Credit: iStock Getting older is a fact of life. As we age, we can grow bigger, smarter and stronger. But at a certain point, our bodies often start to slow down. The idea behind why we age and why our bodies slow down is that we start to lose the ability to make enough energy … Continue reading The Key to Reversing Aging: Folded Mitochondria?

After working out for an hour or so on a hot summer day, you may begin to sweat, get muscle cramps and/or become … Continue reading Sip a Sports Drink to Keep the Electrolytes Flowing
Credit: iStock Are you a fan of spicy foods? You might be in luck. Research presented at Experimental Biology 2021 suggests a specific compound found in fiery foods such as chili peppers may have the ability to help you improve your exercise performance. Capsaicin, the bioactive ingredient in chili peppers, stimulates our pain receptors. This … Continue reading Can Chili Peppers Improve Exercise Performance?
Credit: iStock Experimental Biology (EB) is an annual flurry of science, collaboration and connection, and this year's virtual meeting is no exception. Dr. Dolittle, the American Physiological Society's comparative physiology blogger, caught up with Christian Damsgaard, PhD, of Aarhus University in Denmark, at EB to chat about his work with teleosts, a type of ray-finned … Continue reading Experimental Biology 2021: Q&A with Dr. Christian Damsgaard
Credit: iStock Cardiovascular disease is the leading cause of death in the U.S. In fact, it has been previously predicted that by 2030, cardiovascular disease will affect more than 40% of the U.S. population. With this in mind, it seems clear that we—as a nation—need to improve our cardiometabolic health! A brief glance at health … Continue reading Hot Tubs: The New Home Treadmills?
