Over 20,000 galaxies glimmer in this sweeping view of the sky between the constellations of Pisces and Andromeda. But more than just an arresting sight, the view has helped astronomers determine what sparked the Epoch of Reionization, the period when the opaque universe gave way to the transparent one.First Full-Color Images From Webb Space TelescopeThe earliest days of the universe were cloaked in a dense gas that limited the amount light could travel through it. During the Epoch of Reionization—when the universe was…

New research has found that viruses such as the one that causes COVID-19 can cause brain cells to fuse together and malfunction. The findings might explain the ‘brain fog’ and other neurological symptoms some people experience following infection with the SARS-Cov-2.It’s well-known that some viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19, involve the brain and nervous system by infecting nerve cells (neurons).Some viruses don’t kill their host cells and, instead,…

Of all of COVID-19’s symptoms, one of the most troubling is “brain fog.” Victims report headache, trouble concentrating, and forgetfulness. Now, researchers have shown that SARS-CoV-2 can cause brain cells to fuse together, disrupting their communication. Although the study was only done in cells in a lab dish, some scientists say it could help explain one of the pandemic’s most confounding symptoms. “This is a first important step,” says Stefan Lichtenthaler, a…

Storms, sleet, snow, and even high winds can provide added danger to highways where large vehicles like semitrucks are traveling at high speeds. The abundance of caution and safety is multiplied when you remove the truck driver from the equation. As it prepares to launch its Horizon autonomous service, self-driving tech company Aurora has shared footage of its Driver software responding appropriately when it encounters areas of lower visibility. Check out the video below. Aurora is an…

“This isn’t a fog. This is life under an ice sheet. The term brain fog has everyone I meet expecting I’ll be better any day now.” This is what one of us (Ken) wrote in his journal about the periodic memory loss and inability to concentrate that he experienced throughout 2022, when he struggled with symptoms of long COVID. Long COVID is a neurological disease that happens after people are no longer infected with SARS-CoV-2. Its prevalence appears to be between 15 percent and 30 percent, according to numerous studies.…

CLIMATEWIRE | Arctic sea ice is rapidly vanishing as the world warms, opening up potential new shipping routes across the top of the world. But there’s a catch: Less ice means more fog, making it harder and more dangerous for ships to navigate the thawing sea. It’s an overlooked climate trade-off, according to a new study. And while new Arctic passages often are touted as faster alternatives to conventional shipping routes through the Panama and Suez canals, foggy conditions can cause delays. Fog in the Northwest…

The male desert sandgrouse might not be much to look at, but his belly feathers give him the unique ability to absorb and carry water. Researchers have, for the first time, closely examined the structure of the feathers to see how they absorb water and whether the process might be adapted for human use.When you think of feathers, you probably think of their ability to repel water. Not so the belly feathers of the male desert sandgrouse. He can visit a watering hole, absorb water into his feathers, fly more than 12 mi (20…

The company's cars use a system consisting of lidar sensors, cameras and radar sensors to perceive their surroundings.Alphabet Inc's self-driving technology unit Waymo said on Wednesday that some of its vehicles in San Francisco encountered dense fog and briefly pulled over to the side of the road.The incident, which occurred at around 6.00 a.m. Pacific Time, impeded some traffic movement before the cars moved out of the area as the fog began to clear, Waymo said."We…

Driving in thick fog is a big enough challenge for humans, but it turns out self-driving cars find it pretty tricky, too. Overwhelmed by dense fog in San Francisco early on Tuesday morning, five of Waymo’s fully driverless vehicles suddenly parked by the side of a residential street in what appeared to be a precautionary measure, the San Francisco Chronicle reported. Another of its cars apparently came to halt in the middle of the street, the news outlet said. Other vehicles were unable to pass as “baffled motorists…

Tabletop RPGs are a time-intensive hobby, with some gamemasters spending hours setting up the perfect virtual or physical map for the climax of the D&D session. If you're looking to add a little more pizzaz to your sessions, one Kickstarter will sell you a 3D-printed portal that lets you make your own fog gates, and the effect is pretty impressive.Black Scrolls Games is one of many companies that sells 3D-printed terrain pieces for D&D campaigns, which are intended for use with grid-based combat,…
