In this episode:<h2></h2><h2>00:46 An injectable gel for healing muscles</h2>Severe muscle injury can be debilitating, with long recuperation periods. Now, researchers have developed a material that can be directly injected into injured muscle, helping to stimulate and heal damaged tissue. The team showed this approach could rapidly restore walking ability in severely injured rats and regenerate muscles within four weeks. They hope that this solution could one day help humans with similar injuries, and overcome some of the limitations of current recuperation strategies.Research article: <a href="https://www.nature.com/articles/s41586-023-06628-x" rel="noopener noreferrer" target="_blank">Jin et al.</a>News and Views: <a href="http://www.nature.com/articles/d41586-023-03211-2" rel="noopener noreferrer" target="_blank">Hydrogel implant rehabilitates muscles through electrical stimulation</a><h2></h2><h2>10:02 Research Highlights</h2>Ancient human genomes fill in a missing link between Europe’s first humans and later arrivals, and how ferns are inspiring pest-resistant crops.Research Highlight: <a href="https://www.nature.com/articles/d41586-023-03278-x" rel="noopener noreferrer" target="_blank">Ancient DNA reveals traces of elusive first humans in Europe</a>Research Highlight: <a href="https://www.nature.com/articles/d41586-023-03281-2" rel="noopener noreferrer" target="_blank">Fierce ferns make insect-fighting proteins</a><h2></h2><h2>12:43 Briefing Chat</h2>Largest release of Wolbachia-infected mosquitoes shows promise at controlling dengue, and the genes that explain why starfish aren’t so symmetrical.Nature News: <a href="https://www.nature.com/articles/d41586-023-03346-2" rel="noopener noreferrer" target="_blank">Dengue rates drop after release of modified mosquitoes in Colombia</a>Video: <a href="https://www.youtube.com/watch?v=ZxfTkjkgZt0" rel="noopener noreferrer" target="_blank">How would a starfish wear trousers?
