An anonymous reader quotes a report from Science Magazine: Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. "It's like the embers in a barbecue pit," says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own -- or require extraordinary interventions to avert another accident.

AmiMoJo shares a report from the BBC: The World Health Organization (WHO) has granted emergency approval for the Covid vaccine made by Chinese state-owned company Sinopharm. It is the first vaccine developed by a non-Western country to get WHO backing. The vaccine has already been given to millions of people in China and elsewhere. The WHO had previously only approved the vaccines made by Pfizer, AstraZeneca, Johnson & Johnson and Moderna.
With little data released internationally early on, the effectiveness of the various Chinese vaccines has long been uncertain. But the WHO on Friday sai[...]
Sennheiser has sold its consumer electronics division to a Swiss company called Sonova that specializes in hearing care, Sennheiser has announced. Engadget reports: Sonova said it made the 200 million euro ($241 million) deal to expand its aging demographic to younger customers, particularly in the wireless in-ear segment. "Even if they don't have hearing loss, most of them will gradually get hearing loss with age, and devices like Sennheiser's allow us to have earlier consumer access to such people," Sonova chief Arnd Kaldowski told Reuters. The company said it would build on Sennheiser's HiF[...]
boudie2 writes: According to his own employees, Elon Musk has been exaggerating the capabilities of Tesla's Autopilot system. Documents obtained from the California Department of Motor Vehicles show that despite Musk's tweets to the contrary, "Elon's tweet does not match engineering reality per CJ. Tesla is at Level 2 currently." CJ Moore is the company's director of Autopilot software. "Level 2 technology refers to a semi-automated driving system, which requires supervision by a human driver," reports The Verge. "Tesla is unlikely to achieve Level 5 (L5) autonomy, in which its cars can drive [...]
An anonymous reader quotes a report from The New York Times: Federal health officials on Friday updated public guidance about how the coronavirus spreads, emphasizing that transmission occurs by inhaling very fine respiratory droplets and aerosolized particles, as well as through contact with sprayed droplets or touching contaminated hands to one's mouth, nose or eyes. The Centers for Disease Control and Prevention now states explicitly -- in large, bold lettering -- that airborne virus can be inhaled even when one is more than six feet away from an infected individual. The new language, poste[...]
Video site LiveLeak, best known for hosting gruesome footage that mainstream rivals wouldn't touch, has shut down after fifteen years in operation. In its place is "ItemFix," a site that bans users from uploading media containing "excessive violence or gory content." The Verge reports: In a blog post, LiveLeak founder Hayden Hewitt did not give an explicit reason for the site's closure, saying only that: "The world has changed a lot over these last few years, the Internet alongside it, and we as people." In a video posted on his YouTube channel Trigger Warning, Hewitt offered no further detail[...]
An early look at an ongoing analysis of Apple's App Tracking Transparency suggests that the vast majority of iPhone users are leaving app tracking disabled since the feature went live on April 26 with the release of iOS 14.5. MacRumors reports: According to the latest data from analytics firm Flurry, just 4% of iPhone users in the U.S. have actively chosen to opt into app tracking after updating their device to iOS 14.5. The data is based on a sampling of 2.5 million daily mobile active users. When looking at users worldwide who allow app tracking, the figure rises to 12% of users in a 5.3 mil[...]
An anonymous reader quotes a report from TechCrunch: SpaceX is fresh off a high for its Starship spacecraft development program, but according to CEO Elon Musk, it's already looking ahead to potentially repeating its latest success with an unplanned early reusability experiment. Earlier this week, SpaceX flew the SN15 (i.e. 15th prototype) of its Starship from its development site near Brownsville, Texas, and succeeded in landing it upright for the first time. Now, Musk says they could fly the same prototype a second time, a first for the Starship test and development effort.

A new study suggests some sharks can read Earth's field like a map and use it to navigate the open seas. ScienceMag: The result adds sharks to the long list of animals -- including birds, sea turtles, and lobsters -- that navigate with a mysterious magnetic sense. "It's great that they've finally done this magnetic field study on sharks," says Michael Winklhofer, a biophysicist at the Carl von Ossietzky University of Oldenburg in Germany, who was not involved in the study. In 2005, scientists reported that a great white shark swam from South Africa to Australia and back again in nearly a strai[...]
The average US home-Internet bill increased 19 percent during the first three years of the Trump administration, disproving former Federal Communications Commission Chairman Ajit Pai's claim that deregulation lowered prices, according to a new report by advocacy group Free Press. From a report: For tens of millions of families that aren't wealthy, "these increases are felt deeply, forcing difficult decisions about which services to forgo so they can maintain critical Internet access services," Free Press wrote. The 19 percent Trump-era increase is adjusted for inflation to match the value of 2[...]
