Episode notes

This chapter discusses a breakthrough in 3D printing technology that allows for the creation of fully-formed robots in one go, without the need to add different materials separately. The method incorporates machine vision to bring material compatibilities that were previously not possible, enabling the creation of multi-material constructs with high resolutions and higher throughput.

00:46 Machine vision enables multi-material 3D printing

3D printers are capable of producing complex shapes, but making functioning objects from multiple materials in a single print-run has proved challenging. To overcome this, a team has combined inkjet printing with an error-correction system guided by machine vision, to allow them to print sophisticated multi-material objects. They used this method to make a bio-inspired robotic hand that combines soft and rigid plastics to make mechanical bones, ligaments, and tendons, as well as a pump based on a mammalian heart.

Citizen-scientists help identify an astronomical object that blurs the line between asteroid and comet, and how a Seinfeld episode helped scientists to distinguish the brain regions involved in understanding and appreciating humour.

10:31 Assessing the effectiveness of lifestyle interventions for diabetes

Type 2 diabetes affects hundreds of millions of people around the world and represents a significant burden on healthcare systems. But behaviour change programmes — also known as lifestyle interventions — could potentially play a large role in preventing people from developing type 2 diabetes. This week in Nature a new paper assesses how effective this kind of intervention might be. Looking at a huge amount of data from the NHS Diabetes Prevention Programme, the paper concludes that these interventions represent a viable diabetes prevention strategy.
