The discovery of hybrids in both Texas and Louisiana also suggests that scientists and officials may want to “refocus” their red wolf conservation efforts on those areas, said Lisette Waits, a conservation geneticist at the University of Idaho and co-author of the 2018 paper on the Louisiana hybrids. In addition to studying the hybrids, it […]

It was not the first time in recent memory that people have wondered about seemingly mysterious activities overhead. In December 2018, the sky over New York City erupted in a blue light. People theorized about a U.F.O. flyby or an alien invasion, though the cause turned out to be a transformer explosion at a Con […]

Oh, yeah, I would love to have seen it earlier, but it wasn’t going to happen. There are certain series of missions that are so big they’re called strategic missions. For them to actually happen, the stars have to align. You have to propose it, have a solid case work, go to the NASA administration […]

Robotic missions to Mars and advances in space tourism dominated the space activities of 2021. But in 2022, the moon is likely to stand out, as companies and governments launch various moon-bound spacecraft. Most of those missions revolve around Artemis, NASA’s multibillion dollar effort to return astronauts to the moon later in the decade and […]

PARIS — The deal was simple: Get vaccinated and get your normal life back. In a country with high levels of misgivings about Covid-19 vaccines and citizens quick to challenge authority, the deal was an unexpected success. It turned France into one of Europe’s most vaccinated countries, quashed street protests by government critics, and boosted […]

America was a nation divided, but that did not stop it from building parts of the James Webb Space Telescope in a red state and testing them in a blue one. The European Union and Russia were facing off over Ukraine and other issues this year, but scientists from both sides will benefit greatly from […]

Millions of rapid at-home Covid tests are flying off pharmacy shelves across the country, giving Americans an instant, if sometimes imperfect, read on whether they are infected with the coronavirus. But the results are rarely reported to public health departments, exacerbating the longstanding challenges of maintaining an accurate count of cases at a time when […]

In the pre-vaccine pandemic days, as shutdowns dragged on, odes to the lost joys of the dance floor became a motif in media. Recollections of sweaty nights out in crowded clubs captured much of what Covid had taken from us: community, freedom, gloriously messy physical proximity. When restrictions began to loosen, teeming dance floors became […]

In a holiday season of extreme weather events, this one stands out: a 67-degree Fahrenheit reading in Alaska the day after Christmas. The reading on Sunday, from a tidal station on Kodiak Island, set a statewide temperature record for December, the National Weather Service reported. The temperature at the station, in southern Alaska, reached the […]

People who have recovered from an infection with the new Omicron coronavirus variant may be able to fend off later infections from the Delta variant, according to a new laboratory study carried out by South African scientists. If further experiments confirm these findings, they could suggest a less dire future for the pandemic. In the […]
