In May 2020, some unusual rocks containing distinctive greenish crystals were found in the Erg Chech sand sea, a dune-filled region of the Sahara Desert in southern Algeria. On close inspection, the rocks turned out to be from outer space: lumps of rubble billions of years old, left over from the dawn of the Solar System….
An elusive particle proposed in 1956 by theoretical physicist David Pines has just been discovered by a team of scientists led by Peter Abbamonte of the University of Illinois. Scientists long suspected that this particle, called a ‘demon’, plays a fundamental role in the characteristics of several metals, but had been unable to confirm its…

Around 150 years ago, three scientists named Ernest Rutherford, Hans Geiger, and Ernest Marsden exposed a thin gold foil to radiation. Based on how the rays were deflected by atoms in the foil, they figured out that every atom has a dense centre where its mass and positive charge are concentrated. Seventy years ago, Robert…
