Yes, you read that right. Ornithologists in Australia have received enough witness accounts of birds starting new fires by picking up burning twigs to believe the birds may actually be starting fires deliberately. They think these so-called ‘firehawks’ start fires to flush out prey. Yikes!
A new study published in American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored the effects of modest heat stress (35°C, 95°F) on the physiology of pigs. The found that pigs exposed to heat stress ate less than those exposed to ambient temperatures. I understand. I eat less when it is hot outside too. Since skeletal muscle is such a large metabolically active tissue, things that alter muscle metabolism […]
The growth and development of a human fetus is difficult to study, both practically and ethically, as I am sure you can imagine. A new review article published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored how sheep have helped solve this problem as fetal sheep share similar brain, lung and cardiac development and placental physiology with humans, many aspects of which differ from […]
‘Tis the season. Check out this video from YouTube explaining why certain species of reindeer do indeed have red noses. As Christmas draws near, these blood vessels will help keep Rudolphs’ nose warm as he leads the way for Santa’s sleigh. Sometimes I wish I had more blood vessels in my nose too as my nose is always cold in the winter.
Ever wonder how humans and other animals evolved the ability to detect foods that can potentially harm us? A recent article published in Physiological Reviews, explains the physiology behind why certain foods taste bad. The act of tasting is very complex and includes receptors in our mouths that can detect specific chemicals in our food and prepare our digestive system to receive the food and, as anyone with a cold knows, […]
About a year ago we talked about how Mexican tetra (Astyanax mexicanus) may hold the clues to treating diabetes. New research shows that is not all these tiny fish can teach us. Researchers at the University College London and the University of Oxford now think these fish may hold clues to regenerating damaged heart tissue. Their findings were published in Cell Reports. Mexican tetra are freshwater fish. Over millions of years, […]
Just in time for Thanksgiving… While wild turkeys are known to spend time in the snow, I read an interesting article about the effects of cold exposure on livestock during transport. According to the article, nearly all livestock animals are transported at some point in their life, which can be pretty stressful to the animals. In fact, some turkeys lose weight during transport and others do not even make it […]
