EPFL scientists have developed an injectable gel that can attach to various kinds of soft internal tissues and repair tears resulting from an accident or trauma. 

Researchers at ETH Zurich have developed fluorescent polymers whose colour can be easily tuned. Depending on their length, the polymers emit a different colour. Potential applications include biomedicine, security printing and solar energy.

SwissFEL, the new large research facility at PSI, has been in regular operation since January 2019. And it turns out that this X-ray free-electron laser really is as compact, high-performance, and versatile as planned. "The Swiss Army knife of FELs" is what PSI researcher Henrik Lemke likes to call this large research facility. In an interview, he talks about the latest research successes.

Microplastic pollution is a serious problem, but blanket bans won’t solve the issue, says Denise Mitrano. We should regulate plastics more precisely to create incentives for both innovation and environmental safety.

Researchers at ETH Zurich and Empa have chemically modified wood and made it more compressible, turning it into a mini-generator. When compressed, it generates an electrical voltage. Such wood could serve as a biosensor or as a building material that harvests energy.
