View ArticleAncient gene gives planarians a heads-up in regeneration
A seldom-studied gene known as notum plays a key role in the planarian's regeneration decision-making process, according to Whitehead Institute scientists. Protein from this gene determines whether a...

(PhysOrg.com) -- Scientists have been wrong for 250 years about a fundamental aspect of tissue regeneration, according to a University of Dayton biologist who says his recent discovery is good news for...
View Article3-legged dogs boost robot research
The new research looked at walking and running techniques in dogs with fore-limb or hind-limb amputations, using a treadmill and a set of high-tech infra-red cameras.
View ArticleNew contrast agents detect bacterial infections with high sensitivity and...
A new family of contrast agents that sneak into bacteria disguised as glucose food can detect bacterial infections in animals with high sensitivity and specificity. These agents -- called...

A Murdoch University PhD candidate envisions a future in which everyone wears a low-energy sensor to monitor their health – and he's doing the computing work to make it a reality.
View ArticleThe secrets of a tadpole's tail and the implications for human healing
Scientists at The University of Manchester have made a surprising finding after studying how tadpoles re-grow their tails which could have big implications for research into human healing and...
View ArticleWound healing: 'See-saw' switch sends cells on the march
Many genes are transcribed into messenger RNA (mRNA) molecules that provide instructions for protein synthesis. Other genes encode regulatory RNAs known as 'microRNAs', which can block protein...
View ArticleGenetic factors shaping salamander tails determine regeneration pace
Salamanders' capacity to regrow lost limbs may seem infinite when compared with that of humans, but even amongst salamanders, some species regenerate body parts very slowly, while others lose this...
View ArticleTissue loss triggers regeneration in planarian flatworms
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.

Slicing bread, pouring a cup of coffee, and sitting down at the kitchen table are a part of everyday life for most people, but for people with physical impairments such as limb amputations or...
View ArticleUnraveling the mechanisms behind organ regeneration in zebrafish
The search for the holy grail of regenerative medicine -- the ability to "grow back" a perfect body part when one is lost to injury or disease -- has been under way for years, yet the steps involved in...
