Some good news for cats (and their owners)! Like people, cats can develop chronic kidney disease. In fact, about 10% of felines over the age of 9 years develop it. Common symptoms in cats include weight loss, reduced muscle mass, and often excessive urination and thirst. Other symptoms include metabolic acidosis and more advanced stages may include protein loss in the urine In a new study published in Physiological Reports, researchers […]
A new study seems to have provided an answer to the age-old question of who is smarter: dogs or cats? The speculation before the study was conducted was that hunting may require extra brain cells (neurons). If true, that would mean that cats would have more neurons than dogs. My apologies to all of the cat lovers out there. The findings from the study suggest that dogs may actually be […]
Our lives are regulated by a complex biological clock that controls our circadian rhythms. The master clock is located in our hypothalamus and functions to ensure that specific proteins are turned on or off at the right times. These functions are important not only for cell function, but also for proliferation and survival of species. Of concern to our health is the notion that changes in our exposure to environmental […]
On this Father’s Day, I would like to pay tribute to a few of nature’s most ‘devoted’ fathers. Take the emperor penguin for example. If you have ever watched the movie March of the Penguins, or even Happy Feet, then you know these avian fathers are rock stars of parenting. Males are responsible for keeping the eggs warm for two months while the females go away to feed. They do […]
Check out this study from RMIT University that shows bees understand the concept of the number zero: The paper was published in Science: Howard SR, Avargues-Weber A, Garcia JE, Greentree AD, Dyer AG. Numerical ordering of zero in honey bees. Science. Vol. 360, Issue 6393, pp. 1124-1126 DOI: 10.1126/science.aar4975
Leptin is a hormone that was discovered in 1994 and was once heavily studied by researchers who had hoped it might be useful in promoting weight loss. It is produced by fat cells and signals to the brain whether those fat cells have sufficient energy, at which time it suppresses hunger and thereby promotes weight loss (WebMD; Klok et al., 2007). One of the reasons it failed as a weight […]
I came across a really interesting interview of Dr. Barry Pinshow, a comparative physiologist and member of the American Physiological Society. In this Living History of Physiology video, Dr. Pinshow talks about growing up in South Africa and his decision to move to Israel as a teen. He also discusses how he became interested in science, his research in desert biology and the influential people in his career. Very inspiring!
