- Researchers find a two-dimensional, self-assembling material that might produce solar cells or transistors
- Graphene only as strong as weakest link

Researchers around the world have been working to harness the unusual properties of graphene, a two-dimensional sheet of carbon atoms. But graphene lacks one important characteristic that would make it even more useful: a property called a bandgap, which is essential for making devices such as computer chips and solar cells.

There is no disputing graphene is strong. But new research by Rice University and the Georgia Institute of Technology should prompt manufacturers to look a little deeper as they consider the miracle material for applications.

New research has helped unpick a long-standing mystery about how dietary fiber supresses appetite. In a study led by Imperial College London and the Medical Research Council (MRC), an international team of researchers identified an anti-appetite molecule called acetate that is naturally released when we digest fiber in the gut. Once released, the acetate is transported to the brain where it produces a signal to tell us to stop eating.
