Somewhere on Earth: The Global Tech Podcast

Capturing shooting stars with your doorbell cam

We’ve had the first meteor shower of 2025 – you may have missed it but your doorbell cam may have recorded it. The Quadrantids shower has captivated both amateur and professional astronomers, some of whom are now working together to find the meteors once they land on the Earth’s surface. When this occurs, there is a strong likelihood that the aptly named UK Fireball Alliance will identify them. This alliance consolidates images and videos from various sources, including doorbell cameras, dash-cams, security systems, and professional telescopes. The primary objective is to issue a comprehensive alert to scientists, indicating where they can locate the fallen meteors. Gareth met with Luke Daly, a lecturer in planetary geoscience at the University of Glasgow. He is also the treasurer of the UK Fireball Alliance and is on the show to tell us more.

EdTech Apps – are they any good?

The EdTech App market is worth billions of dollars a year but many of these apps are, in fact, counterproductive and may be causing more harm than good. That’s according to an Educational Technology researcher who has recently expressed her concerns in the journal Nature. Natalia Kucirkova, the Director of the International Centre for EdTech Impact and a professor at the University of Stavanger in Norway, is concerned that educational institutions, along with families, are squandering resources on apps that do not yield effective results. As she tells Gareth, better testing of these apps is needed, as is a certification process to identify those that are truly beneficial to children.

The programme is presented by Gareth Mitchell and the studio expert is Angelica Mari.
