Sun-powered flyers could explore the mysterious mesosphere

00:46 Tiny solar flyer

Researchers have used a phenomenon known as thermal transpiration to create a solar-powered flying device that can stay aloft without any moving parts. The diminutive device, just one centimetre across, consists of two thin, perforated membranes that allow air to flow through the device, generating lift. Although only a proof-of-concept, the team hope that a scaled-up version of the device could be used to measure conditions in the mesosphere, a particularly hard-to-study part of the Earth’s atmosphere, or even on Mars.

10:22 Quantum gravity goes to the lab

Despite being one of the most successful scientific frameworks in history, there is one thing that quantum physics can’t explain: gravity. Whether gravity is quantum in nature is something that has had physicists vexed, but now a slew of experiments are being planned to try and answer this question. We hear how these experiments will work, and what their results might mean for physicists’ understanding of the universe.
