Today we have an update on the biggest astrophysics drama of the year, that’s an observation which seems to be ruling out the most popular alternative to dark matter. Then we have a group of geologists who claim that parts of the moon are stuck in the mantle of earth, a new and quite plausible explanation for the sudden dimming and brightening of the star Betelgeuse, plans for a smaller and more energy-efficient particle collider, the first full colour images from the EUCLID mission, earthquakes in the laboratory, a microscopic engine with record efficiency, plans to produce hydrogen with small nuclear reactors, climate scientists who say we’d be better off cooking with synthetic oil, and of course, the telephone will ring.
