Bone can heal itself, but not always in the ways we expect. Some animals regrow entire limbs. Others, like humans, can only ...

Axolotls are able to achieve this sort of regeneration because they react to injuries in an entirely different way than humans. When we are injured, a wound from a severed limb simply gets covered ...

Genes involved in wound response, including immunity- and cell migration-related functions, are activated during the early phases of regeneration while later stages are marked by increased activity of ...

Background Limb asymmetries have been identified as a significant predictor of injury risk. However, the natural boundaries of variation in a non-injured population using clinically relevant and ...

Animals show a quite interesting phenomenon called reconstitution, even after establishing their body structure through embryogenesis. A frog drastically changes its ...

And new data suggests that the optimization process can be fine-tuned: booster shots elicited higher quality memory B cells in mice when they were given in the same limb as the original dose, ...
