By Leah Crane A 3D-printed isotropic helicoid G. Voth/Wesleyan University A strange shape described by mathematician Lord Kelvin in 1871 and predicted to behave unusually in a fluid has finally been fully studied in the real world thanks to 3D printing – and it seems Kelvin may have been wrong.
By Matthew Sparkes NASA’s Deep Space Atomic Clock, the first GPS-like technology for deep space General Atomics Electromagnetic Systems A toaster-sized atomic clock orbiting Earth is 25 times more accurate than existing space clocks and will soon be tested on a mission to Venus. The highly accurate timepiece could improve
By James Urquhart [embedded content] Stainless steel foil that normally sinks in water has been made so water-repellent that not only is it unsinkable, it appears to defy gravity by jumping out of water too. Jiann Shieh at the National United University in Taiwan and his team chanced on the
By Chanda Prescod-Weinstein David Kashakhi/Alamy PART of what turned me into a theoretical cosmology enthusiast as a child was watching the documentary A Brief History of Time and hearing about the mystery around the big bang. It showed how the equations that we use to describe space-time broke down into
By Leah Crane One of the 40-kilogram mirrors that has been cooled to near absolute zero Caltech/MIT/LIGO Lab A set of four mirrors used by the Laser Interferometer Gravitational-Wave Observatory (LIGO) to detect ripples in space-time have been cooled down so much that they are nearly at their minimum-energy state.
By Matthew Sparkes The ITER fusion reactor will contain the world’s largest magnet, which stands vertically in the centre of this illustration ITER The world’s most powerful magnet is being shipped to France for installation in the core of ITER, the experimental fusion reactor. It is hoped that ITER will
