Just over five years ago, on 22 February 2019, an unmanned space probe was placed in orbit around the Moon. Named Beresheet and built by SpaceIL and Israel Aerospace Industries, it was intended to be the first private spacecraft to perform a soft landing. Among the probe’s payload were tardigrades, renowed for their ability to survive…
As the world rushes to make use of the latest wave of AI technologies, one piece of high-tech hardware has become a surprisingly hot commodity: the graphics processing unit, or GPU. A top-of-the-line GPU can sell for tens of thousands of dollars, and leading manufacturer NVIDIA has seen its market valuation soar past US$2 trillion as demand for…
