Schools in the U.K. are removing analog clocks from exam rooms after students complained about not being able to read the time, according to The Telegraph.Malcom Trobe, deputy general secretary at the Association of School and College Leaders, says students are accustomed to using digital devices today."They are used to seeing a digital representation of time on their phone, on their computer," Trobe told The Telegraph. "Nearly everything they've got is digital so youngsters are just exposed to time being given digitally everywhere."Teachers are concerned about students stressing out during exams because they can't keep track of time. One educator said her high schoolers are only able to tell the time on devices with digital displays, which they can't use during exams, according to People.Many teachers turned to Twitter to share their experience and found that issues with analog clocks is a common trend. 935

Scratch and sniff stickers have gone high tech, becoming another way to test for coronavirus.Researchers at the University of Colorado and Yale University have developed a “u-Smell-it” test that works with an app.Essentially, users will use a high-tech scratch and sniff to detect whether they've lost their sense of smell.“There's five windows and they have different odors on each of them. Basically, all you have to do is take an app on your phone, and you basically scan the card. It has a QR code, and it recognizes the unique combination of odors. This is really important because you want the test to be different every time,” said Derek Toomre, professor at the Yale University School of Medicine.The user will choose the corresponding odors. And after, they're done. The app will give them a score on how well they did or didn't do.This test isn't meant to replace the PCR test or antibody tests that are approved by the FDA.“This would be a supplement. This would not be to replace. This would be a supplement so that, if you failed to smell, then you would know to go in for an antigen or PCR test, but you're more likely to be positive on those tests, so it would actually be really, really helpful. Think of it as a pretest.”Researchers behind the “u-Smell-it” test hope that it will help with the current testing shortage. Right now, they are seeking FDA approval for emergency use. If approved, they'll be making the tests at a larger scale. 1464

SANTA CLARA, Calif. (AP) — Intel has revealed another hardware security flaw that could affects millions of machines around the world.The bug is embedded in the architecture of computer hardware, and it can't be fully fixed."With a large enough data sample, time or control of the target system's behavior," the flaw could enable attackers to see data thought to be off-limits, Bryan Jorgensen, Intel's senior director of product assurance and security, said in a video statement.But Intel said Tuesday there's no evidence of anyone exploiting it outside of a research laboratory. "Doing so successfully in the real world is a complex undertaking," Jorgensen said.It's the latest revelation of a hard-to-fix vulnerability affecting processors that undergird smartphones and personal computers. Two bugs nicknamed Spectre and Meltdown set a panic in the tech industry last year.Intel said it's already addressed the problem in its newest chips after working for months with business partners and independent researchers. It's also released code updates to mitigate the risk in older chips, though it can't be eliminated entirely without switching to newer chips.Major tech companies Google, Apple, Amazon and Microsoft all released advisories Tuesday to instruct users of their devices and software, many of which rely on Intel hardware, on how to mitigate the vulnerabilities.As companies and individual citizens increasingly sign their digital lives over to "the cloud" — an industry term for banks of servers in remote data centers — the digital gates and drawbridges keeping millions of people's data safe have come under increasing scrutiny.In many cases, those barriers are located at the level of central processing unit, or CPU — hardware that has traditionally seen little attention from hackers. But last year the processor industry was shaken by news that Spectre and Meltdown could theoretically enable hackers to leapfrog those hardware barriers and steal some of the most securely held data on the computers involved.Although security experts have debated the seriousness of the flaws, they are onerous and expensive to patch, and new vulnerabilities are discovered regularly.Bogdan Botezatu, director of threat research for security firm Bitdefender, said the latest attack was another reason to question how safe users can really be in the cloud."This is a very, very serious type of attack," Botezatu said. "This makes me personally very, very skeptical about these hardware barriers set in place by CPU vendors."Intel said it discovered the flaw on its own, but credited Bitdefender, several other security firms and academic researchers for notifying the company about the problem.Botezatu said Bitdefender found the flaw because its researchers were increasingly focused on the safety and management of virtual machines, the term for one or more emulated mini-computers that can be spun up inside a larger machine — a key feature of cloud computing. 2976

SAN FRANCISCO, Calif. (AP) — Gov. Gavin Newsom says California is turning the corner in its fight against the coronavirus pandemic. He cited a significantly lower number of confirmed new cases as California begins to clear backlogged cases caused by a technical error. Newsom says he's also encouraged by the downward trend in hospitalizations, which have fallen 21% in the past two weeks. Dr. Roger Lewis, director with the Los Angeles County Department of Health Services, says there’s been “a clear decline” in hospitalizations there. California reported 180 additional deaths from the virus Wednesday, bringing the state's coronavirus deaths to more than 10,600. 674

Security is being questioned after a plane was stolen from the Seattle-Tacoma International Airport on Friday. As officials look into how this happened, investigative reporter Jace Larson finds out more about the man piloting the plane.Richard Russell seemed coherent in his final conversations with air traffic control."I've got a lot of people that care about me, and uhh... it's gonna disappoint them to hear that I did this.”Russell did some aerial stunts while refusing air traffic control’s attempts to have him land.Russell’s final words were captured on radio, and he was apologetic to those he loved."Just a broken guy. Got a few screws loose, I guess,” Russell could be heard saying. “Never really knew it, until now."One of Russell's co-workers was surprised to hear his voice."You could tell he was in pain,” says Jeremy Kaelin, a former co-worker of Russell. “Kind of seemed a little delusional, and I was just shocked to see that someone who was so nice, so helpful and caring, actually he cared about his job, to do such a thing and you know and end his life."Russell had access to secure aircraft areas as a ground service agent and had knowledge on taxiing planes around the airport.Protocol requires two people to be present to tow the plane. Authorities are still unsure how Russell managed to access the plane alone and move it by himself."We believe he was in uniform,” says Brad Tilden, CEO of Alaska Airlines. “His job is to be around airplanes. He is tow certified, so he's meant to be-- airports have a non-secure side and a secure side. He's meant to be on the secure side. That's a part of the fulfillment of his job responsibilities."Once in the air, military jets were sent to follow Russell to make sure he didn't do anything dangerous."Military jets were scrambled from Portland, but it does not appear that the jets were involved in the crash of the Horizon aircraft," says Gary Beck, CEO of Horizon Air.The National Transportation Safety Board says Russell crashed through several lines of 10-foot-high trees. 2050
