Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while ...
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [1] Every species is capable of regeneration, from bacteria to humans. [2][3][4] Regeneration can either be complete [5] where the ...
Morphallaxis. Morphallaxis is the regeneration of specific tissue in a variety of organisms due to loss or death of the existing tissue. The word comes from the Greek allazein, (αλλάζειν) which means to change. The classical example of morphallaxis is that of the Cnidarian hydra, where when the animal is severed in two (by actively ...
Deer grow antlers anew each spring, often at the rate of an inch per day. Now, scientists want to take the cells that power deer antler growth and figure out how to give that same ability to humans.

Cold and heat adaptations in humans are a part of the broad adaptability of Homo sapiens. Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research ...
Dec. 10—With the help of pink alien-looking salamanders about the size of a hot dog, scientists at a Bar Harbor laboratory are hoping to unlock secrets about how humans can regrow their limbs ...
The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.
