Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
A new study analyzes the blood cells of bats (of both the hibernating and non-hibernating varieties) and humans to understand the role these cells play in keeping mammals alive during prolonged ...
Humans still don’t need to hibernate, Weiss said, nor can we afford to due to our social and occupational obligations. “But we can make adjustments to perform in a better way, to rest in a ...
States of suspended animation are common in micro-organisms and some plant tissue, such as seeds. Many animals, including large ones, may undergo hibernation, and most plants have periods of dormancy. This article focuses primarily on the potential of large animals, especially humans, to undergo suspended animation.
A hibernation factor is a protein used by cells to induce a dormant state by slowing or halting the cellular metabolism. [1] This can occur during periods of stress, [ 1 ] randomly in order to allocate "designated survivors" in a population, [ 1 ] or when bacteria cease growth (enter stationary phase ). [ 2 ]
Hibernation is a mechanism used by many mammals to reduce energy expenditure and survive food shortages over the winter. Hibernation may be predictive or consequential. An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period.
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
The black bear had hay in his hair, looked disoriented, and basically looked like what most of us tired humans look like every morning! Miller Zoo commenters couldn't help but laugh at Buddy's ...
