00:47 The robot shoulder that exercises cells
Recreating 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.

10:30 Overcoming COVID-19 vaccine hesitancy
Identifying sources of vaccine hesitancy is a key challenge in public health. This week, a team show that correcting misperceptions about doctor’s COVID-19 vaccine views increased vaccination rates in the Czech Republic. The team suggest this finding could extend to other countries, and represents a cost-effective intervention for reducing vaccine hesitancy.
