On a rainy Thursday in Tuktoyaktuk, NWT, last week a group of children, using paper and a sewing needle, built an amplifier for the turntables they were learning to build. It was part of a four-week camp in July that incorporates traditional learning with science, technology, engineering, and math, also known as STEM fields. “I …

In February, for the first time, a Black Hawk helicopter flew alone with no humans on board. The autonomous military helicopter project involved both DARPA and Sikorsky, which produces the UH-60 helicopters. Meanwhile, in some places, companies like Zipline and Wing deliver goods via drones. Other companies are working on electric air taxis to transport …

If the era of quantum computing began 3 years ago, its rising sun may have been hiding behind a cloud. In 2019, Google researchers claimed they passed a milestone known as quantum supremacy when their Sycamore quantum computer performed an abstruse computation in 200 seconds that would have blocked a supercomputer for 10,000 years. Now, …

The pigs had been lying dead in the lab for an hour: there was no blood circulating in their bodies, their hearts were still, their brainwaves flat. Then a group of Yale scientists pumped a bespoke solution into the bodies of the dead pigs with a device similar to a heart-lung machine. What happened next …
