00:45 Researchers develop a new glue and test it on a rubber duckAided by machine learning, researchers have developed a super-sticky compound that works as an underwater adhesive. Inspired by animals like barnacles, the team developed a new kind of a material called a hydrogel. The material is capable of securely fastening objects together even when immersed in salty water— a challenge for existing adhesives. To show off its properties the researchers applied it to a rubber duck, which stuck firmly to a rock on a beach despite being battered by waves.Research Article: Liao et al.News and Views: AI learns from nature to design super-adhesive gels that work underwater07:37 Research HighlightsThe tomato-infused origins of the modern potato — plus, a specific group of stem cells that may help to drive osteoarthritis.Research Highlight: Potato, tomato: the roots of the modern taterResearch Highlight: Ageing stem cells in the knees drive arthritis damage09:46 The diversity of microbes within li
