Robot exercises shoulder cells for better tissue transplants
00:47 The robot shoulder that exercises cellsRecreating the movements that tendon cells experience as they develop in the human body is necessary for growing tissue for transplantation, but this has been difficult to achieve in a laboratory setting. Now, a team has developed a system that uses a robot shoulder to stretch and twist these cells, which they hope could be used to improve the quality of tissue grafts in the future.Research article: Mouthuy et al.Video: A robotic Petri dish: How to grow human cells in a robot shoulder07:56 Research HighlightsA robotic surgeon that works within an MRI chamber, and an ancient huma...

Fixing fat bubbles for vaccines, and preventing pain from turning chronic
On this week’s show: Lipid nanoparticles served us well as tiny taxis delivering millions of mRNA vaccines against COVID-19, but they aren’t optimized—yet, and why we might need inflammation to stop chronic pain The messenger RNA payload of the mRNA vaccines against SARS-CoV-2 is wrapped up in little fatty packets called lipid nanoparticles (LNPs). These fat bubbles were originally designed for something much different—carrying molecules into cells to silence genes. But they were useful and we were in a hurry, so not much was changed about them when they were pressed into service against COVID-19. ...
