Scientists have discovered that bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth’s atmosphere, preventing them from burning up. This is the conclusion of a new study carried out by a researcher from Imperial College London. Cosmic dust particles originate from events such the arrival of comets in the inner solar system and collisions between asteroids, which pulverises them into dust. Some make…

When Geoffrey Coates, the Tisch University Professor of Chemistry and Chemical Biology, gives a talk about plastics and recycling, he usually opens with this question: What percentage of the 78 million tons of plastic used annually for packaging – for example, a 2-liter bottle or a take-out food container – actually gets recycled and reused in a similar way? The answer, according to the Ellen MacArthur Foundation, is just 2%….
