What sponges can tell us about the evolution of the brain

Despite its central importance, the brain's origins have not yet been uncovered. The first animal brains appeared hundreds of millions of years ago. Today, only the most primitive animal species, such as aquatic sponges, ...

How you mix cells changes the brain

Brain organoids are models of the brain made from growing stem cells like iPS cells into three-dimensional structures. They are used to study all sorts of brain-related phenomenon, including neural networks and disease development. ...

Using nanofibers to stop brain tumor cells from spreading

Brain cancer is difficult to contain and is often resistant to conventional treatment methods. Predicting tumor cell behavior requires a better understanding of their invasion mechanism. Now, researchers from University of ...

What makes us human? The answer may be found in overlooked DNA

Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers at Lund University in Sweden have now found a previously overlooked part of our DNA, so-called ...

Team rewires a behavioral circuit in a worm using hydra parts

For two people to communicate in a loud, crowded room, they need to be standing side by side. The same is often true for neurons in the brain. But the same way a cell phone allows two people to communicate clearly across ...

Controlling carbs and fat: Learning from the fruit fly

Incretins are hormones secreted by intestinal cells that regulate pancreatic insulin and glucagon to control sugar metabolism in mammals. Although counterparts of insulin and glucagon have been identified in invertebrates, ...
