The key is to evenly distribute elderly passengers, who move more slowly, among the aircraft cabins. The Federal Aviation Administration (FAA) requires that, in the event of an emergency, all airplane passengers must be able to evacuate any aircraft within a 90-second window. But is that a realistic requirement,…
“Things are certainly starting to feel real here at the Cape.” KENNEDY SPACE CENTER, Florida—The two-day countdown for the launch of NASA’s Artemis II mission began Monday evening, with clocks timed for the first of six opportunities in early April to send a crew of four astronauts around the…
Building the big electric SUV at two sites doesn’t make sense anymore. The Volvo factory outside Charleston, South Carolina, will get even busier this year. Formerly the site that built the S60 sedan, in recent years it shifted to building big electric SUVs, the EX90 and closely related Polestar…
Factory Zero went idle on March 16, workers expected to return April 13. After getting a little overoptimistic about the speed and nature of electric vehicle adoption in the US, automakers are now scaling back their production plans. The imposition of tariffs and the abolishment of federal EV incentives…
F1 cars don’t have enough energy in a lap to attack fast corners, and that’s bad. Following this past weekend’s Japanese Grand Prix, Formula 1 goes into a five-week hiatus now that war in the Gulf has made it impossible to hold races in Bahrain and Saudi Arabia. The…

Breathing capacity could have compensated for lower atmospheric oxygen. Three-hundred million years ago, the skies of the late Palaeozoic era were buzzing with giant insects. Meganeuropsis permiana, a predatory insect resembling a modern-day dragonfly, had a wingspan of over 70 centimeters and weighed 100 grams. Biologists looked at these…
A quantum experiment shows that we can formally test if the order of events matters. Over a decade ago, when I was first starting to pretend I could write about quantum mechanics, I covered a truly bizarre experiment. One half of a pair of entangled photons was sent through…
Specially equipped nets can help save some species, while allowing fisherman to still catch others. Our oceans are full of sophisticated, perfect traps: Nets, hooks, fishing lines. Designed to capture animals destined for our dinner tables, they often catch other wildlife too. This accidental harvest is known as bycatch,…
