Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research has found that stem cells in the freshwater planarian Schmidtea ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Nelson Hall wants you to know that the googly-eyed flatworm he just sliced into four pieces is going to be OK. In fact, it’s going to be great. Three of the flatworm’s four pieces have started to ...

A wide variety of distantly-related animals, including flatworms, newts and zebrafish, have robust abilities to regenerate damaged or missing body parts. A new study shows little evidence of a common ...

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 ...

Flatworms are infamous in biology labs for their surreal ability to regenerate heads when you decapitate them. Now, researchers have discovered that an odd developmental defect can cause them to grow ...

A team of scientists has mapped the regions surrounding stem cells in planarians—small flatworms that are famous for being able to regrow whole bodies from small fragments—and discovered something ...

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 ...
