Dozens of mammoths under new airport At least 60 mammoth skeletons have turned up in excavations for a new airport north of Mexico City — and more are likely to come. “There are too many, there are hundreds,” says archaeologist Pedro Sánchez Nava. The site is on what used to be the shores of a lake called Xaltocan, where a military airport is now being converted to civilian use. The wealth of remains suggests that mammoths died after being chased by prehistoric humans some 15,000 years ago and getting stuck in the mud. Smithsonian | 5 min read

How circuits simulate hyperspace geometry

Physicists have created a virtual crystal with four spatial dimensions that acts as a topological insulator — a material that conducts electricity on only its outer boundary. To do so, the team wired up connections among electrical circuits to simulate those in a four-dimensional (4D) crystal. (Just as cubes have six square faces, hypercubes have eight cubic ‘faces’ — so when hypercubes are stacked in 4D, each one is in contact with eight neighbours.) A similar scheme could extend to even more dimensions of space, leading to the observation of new phenomena. “There are suggestions that some really cool things could happen in 5D and 6D,” says theoretical physicist Hannah Price. Exotic topological insulators could find applications in future quantum computers.
