A situation like this would result in less milk available to each nursing pup. I just read an interesting paper published in Physiology. Animals periodically undergo periods of food deprivation such as during hibernation, mating, molting and migration. During these period of […]

Researchers discover new genes that protects water bears when they dry out

Water bears, aka tardigrades, are resilient little creatures. These microscopic animals can survive both freezing and boiling temperatures, radiation, high pressure, starvation, the vacuum of space and even desiccation. This last ability caught the attention of a team of researchers interested in how they are able to survive for years despite being completely dried out, an ability known as anhydrobiosis. Video by Daiki D. Horikawa, via YouTube. The team discovered special genes that […]
