A new wearable device that claims to turn your body into a biological battery has been developed by scientists at Colorado University, according to a story in The Daily Mail. The stretchy device attaches to the skin like a ring sits on a finger and taps into the user’s natural heat to convert the body’s internal temperature into electricity. Although currently only generating about one volt of electricity, the team eventually sees the technology evolving to the size of a sports wristband that can produce about five volts, allowing you to power other wearable electronics on the go.

Facebook has been accused of using nondisclosure agreements (NDAs) to try to build a “wall of secrecy” and prevent its moderators from discussing working conditions with Leo Varadkar, the Irish tánaiste (deputy PM). The workers, who are being forced to work in the company’s Dublin office throughout Ireland’s high-tier lockdown, were afraid of being sacked if they spoke to Varadkar about their working conditions and have sought guarantees from the social media giant they will not face legal action for doing so.
