In a June letter to Nature Ecology and Evolution1, 19 researchers from around the world warned that job losses during the pandemic
WASHINGTON — Xtar, a company that provides satellite communications services to the U.S. government, has sold its only satellite to Hisdesat, one of its shareholders. Virginia-based Xtar signed a leasing agreement that allows it to retain the same amount of capacity on the satellite, Xtar-Eur, despite the change in ownership, Jay Icard, Xtar’s chief executive,
Plenty of prognostications, including this one from the World Economic Forum, tout the integral role artificial intelligence could play in “saving the planet.” Indeed, AI is integral to all manner of technologies, ranging from autonomous vehicles to more informed disaster response systems to smart buildings and data collection networks monitoring everything from energy consumption to

Mars 2020, the spaceship carrying NASA’s new rover Perseverance to the Red Planet, is experiencing technical difficulties and is running on essential systems only, the agency said Thursday. “Data indicate the spacecraft had entered a state known as safe mode, likely because a part of the spacecraft was a little colder than expected while Mars

Deep-sea angler fish have a bizarre reproductive strategy, compared to other animals. This reproductive strategy costs them their acquired immune functions, yet they are thriving, giving new hope to human patients who have inborn or acquired immune disorders. The males, guided by pheromone and lights from the female’s bioluminescent lure, find their mates. Once they have
The CBETA accelerator at Cornell University, New York, is designed to recoup the energy it pours into making high-energy electron beams. Credit: Cornell University Particle physics 31 July 2020 Most linear accelerators are energy hogs, but a new model recovers waste energy that can be ploughed back into the system. Linear accelerators excel at speeding
WASHINGTON — The U.S. Federal Communications Commission on July 30 approved Amazon’s request to operate a constellation of roughly 3,200 internet satellites in low Earth orbit. The FCC said Amazon has until July 30, 2026 to launch at least 50% of its satellites in order to maintain its authorization, and until July 30, 2029 to
Farming is a tough business where success depends on a range of factors, including the weather. Hard frosts and flooding can be particularly damaging to those who grow crops and rear livestock, while severe droughts also have the capacity to wreak havoc. One country that’s been hit hard by drought is Zimbabwe, in southern Africa.
