    How fintech startups can help the underserved and make a profit
    Working as a tech journo, I meet many people with big, world-changing ideas. But despite the hyperbole, when I ask about how they are going to achieve their aims – or indeed if they are already up and running, who they have helped – the Zoom call often gets really quiet.  So when I meet someone who is making the lives of some of the most disadvantaged people in the world a better place, and they’re using tech to do so, I get wildly excited.  This week I had the pleas

    NASA taps into the magic of diffraction to build solar sailing spacecraft
    Sails have propelled earthlings across the seas for millennia, but NASA believes their future is off-world. The space agency has unveiled plans to develop a new solar sail system for a demonstration mission.

    Electric mobility is hot, but its lithium-ion batteries are burning
    Not a week goes by without seeing a video, news item, or tweet about a lithium-ion battery fire. Just over the weekend, there was news in Canada of a Tesla Model Y 2021 driver who had to break a window to escape after his car shut down and caught fire unexpectedly.

    What are nuclear isomers? And why are they so awesome?
    Nobel laureate Otto Hahn is credited with the discovery of nuclear fission. Fission is one of the most important discoveries of the 20th century, yet Hahn considered something else to be his best scientific work. In 1921, he was studying radioactivity at the Kaiser Wilhelm Institute for Chemistry in Berlin, Germany, when he noticed something he could not explain. One of the elements he was working with wasn’t behaving as it should have. Hahn had unknowingly discovered the first nuclear is
