CAMBRIDGE, Mass. (May 12, 2011) – Ever since animals, such as lizards and starfish, were observed regenerating missing body parts, people have wondered where the new tissues come from. In the case of ...

Scientists have discovered a key biological safeguard that helps one of nature's most impressive regenerators, the planarian ...

Forbes contributors publish independent expert analyses and insights. I write about biodiversity and the hidden quirks of the natural world. Imagine waking in the morning with no brain, and no memory ...

An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria -- the small worms whose power to regrow body parts makes them a research model in ...

Add Yahoo as a preferred source to see more of our stories on Google. A tiny animal with an extraordinary ability could teach us how to regenerate lost or damaged body parts. A beheading is lethal for ...

Unlike humans, planarian flatworms have the remarkable ability to regrow any missing body part, making them an ideal model with which to study the molecular basis of regeneration. Over the years ...

FINDINGS: Devising a novel method to identify potential genetic regulators in planarian stem cells, Whitehead Institute scientists have determined which of those genes affect the two main functions of ...

Planarian worms could show the way for tissue regeneration. For they have an amazing ability to regenerate body parts, including a head and brain, following amputation. These remarkable creatures ...

In the present study, we specifically crossed individuals with known genotypes. Using four highly polymorphic microsatellite loci, we compared genotypes of both adults and offspring to examine the ...

The ability of some animals to regenerate body parts has been a source of fascination since at least the eighteenth century. In recent years, the power of molecular genetics has been brought to bear ...

Similar to humans, planarians have brains, similar organs, and stem cells, so they are often used as model organisms for basic research. In addition, it is known that planaria has totipotent stem ...
