A West Virginia University biologist is studying why some animals can regenerate while others cannot and has identified the genes that play a role in the process. Christopher Arnold, assistant ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on ...

Losing a limb or an organ is life-altering for most creatures, but not for all. Some animals have evolved regeneration skills that go far beyond healing scrapes or broken bones. These species can ...

Our bodies can adapt to changes in the environment. For example, whether it’s hot in summer or cold in winter, our internal temperature stays steady at 37°C. This ability is due to a process called ...

Imagine losing a limb and growing it back like nothing ever happened. Sounds like science fiction? Not for many animals in the natural world! While humans are capable of healing cuts and fractures, ...

Learn how axolotls are able to fully regenerate their thymus, a small organ that trains immune cells to fight infections.

At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -- but how? Regenerating functional tissue across species, including ...

This image shows Xenopus laevis swimming in a tank pre-amputation. [Celia Herrera-Rincon/Tufts University] Scientists at Tufts University have developed a wearable bioreactor that can promote partial ...

This ability is widespread in the animal kingdom, but its distribution is spotty. Salamanders are the best-known regenerators, but cockroaches can regrow legs, Drosophila can renew discs, deer regain ...

A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults. Scientists have ...

An image of a planaria, a flatworm that can regenerate its entire body, under a fluorescent microscope. WVU research, led by biologist Chris Arnold, is looking at genes that lay the framework for ...
