Blood tests are part of the process of receiving cancer treatment. But they can be time-consuming and require visits to hospital. A new blood test machine is changing this. The Liberty is a small device that allows patients to take blood tests and upload the results from home without supervision. Lynn Thompson took part in the trial, and she tells Tech Life it's made a huge difference to her life. Also this week, we answer a listener's question about smart glasses. We learn about a project, involving electrolysers and hydrogen cooking stoves, which could improve the health of villagers in rural Nepal. And cutting down on e-waste - we speak to Tech for Troops.
