A cure for ageing, without the price-tag? It might sound too good to be true, but the team digs into <a href="https://www.newscientist.com/article/2354698-a-blast-of-ultrasound-waves-could-rejuvenate-ageing-cells/" rel="noopener noreferrer" target="_blank">new evidence that shows low-frequency ultrasound may rejuvenate cells in our body which are thought to cause age-related diseases</a>.&nbsp;Our galaxy, <a href="https://www.newscientist.com/article/2354280-the-milky-way-seems-to-be-missing-nearly-half-of-its-regular-matter/" rel="noopener noreferrer" target="_blank">the Milky Way, is missing half of its matter</a> - and the team asks where it’s all gone. They also discuss NASA’s ShadowCam which has taken pictures of Shackleton Crater on the south pole of the Moon, a region of particular interest if humans are to settle on the Lunar surface.Despite dramatic heat waves over the past few years, the Earth has actually been in a cooling period, known as La Niña, for the last three years.

And as the team finds out, they even do it in a pretty gruesome way, using a sort of nerve gas. The question is, can they still be considered vegan?For a unique take on the climate crisis and the personal responsibility we feel in tackling it, Rowan chats to <a href="https://twitter.com/AssaadRazzouk" rel="noopener noreferrer" target="_blank">Assaad Razzouk</a>, author of Saving the Planet Without the Bullshit: What They Don't Tell You About the Climate Crisis.
