Proponents of the fermented liquid seem to think it can cure just about any ailment, and sometimes advise taking shots of it to stave off illness. Cider vinegar is just one in a sea of trendy superfoods that plague the web, but it’s a great example of how easy it is to ascribe unfounded health benefits to generally innocuous ingredients. Apple cider vinegar won’t magically make your problems go away, no matter how much you believe in it....

Hyundai notes that the solar cells could provide a boost of about 808 miles annually. In other words, if you drove this car every day for a year, you’d be getting about 2.2 miles of daily travel from the sun, on average. Unlike with plug-in charging or previous attempts at cars with photovoltaics, the solar system shunts power to the Sonata’s battery even when you’re driving. And in October of last year, Hyundai announced that they have been working on different types of solar cells for cars, one of which is designed to juice the battery of a car with an internal-combustion engine, “thereby improving fuel efficiency,” they argue....

But even as the species teeters on the edge of extinction, the federal government hasn’t stepped in to save it. In 1999, when the insect’s population still numbered above a thousand, the nonprofit Center for Biological Diversity petitioned the US Fish and Wildlife Service (FWS) to grant the butterfly legal protection under the Endangered Species Act (ESA). Since then, the agency has received and declined another petition to list the vanishing critter, and is presently considering a third....

So far, car companies have had trouble keeping up with computing advances. While Apple issues a new iPhone annually, General Motors needs to finalize in-dash hardware and software years before a car reaches the market. But automakers could soon cede much of the software development to the same engineers who write smartphone apps. Today you can connect your phone to your car using a USB cable; the vehicle’s software will load your music and your contacts....

In contrast to what their name implies, supermassive black holes can be one of the brightest sources of continuous light in the universe. Their extreme gravitational pull brings in all kinds of material that manifests as a bright ring, or corona, around the so-called event. Little is known about supermassive black hole coronas, so scientists turned to black hole I Zwicky 1, which lies 100 million light-years from Earth, to investigate the beams shooting out....

Which emoji do those singles use? Women and men are united in their most and least popular choices:

This will be separate from the ‘Home’ tab, which will continue recommending content to users in a TikTok-like way. The Home tab will continue to be powered by an algorithm that recommends content that it feels may be relevant or of interest to the user. The company says that this tab will work like a “discovery engine.” This change should be rolling out to users in the coming week, and they can access these two tabs through the shortcut bar on the bottom panel....

The FDA’s decision, based on lab studies of the treatments, mirrors the practices of many healthcare providers, who had been administering the two drugs to treat lingering Delta infections, but stopped as Omicron cases dominated. Monoclonal antibodies are lab-grown versions of antibodies that the immune system would make against COVID after an infection or vaccination. They’re given via an infusion (a bit like an IV drip) within five days of a patient developing symptoms in order to soup up the early immune response....

Understandably, everyone’s got SARS-CoV-2—the coronavirus behind the COVID-19 pandemic—on their minds. But even amidst a global emergency, we should take care not to forget the existence of the countless other microbes that surround us. Not all bugs are bad (in fact, trillions exist on or inside us that we can’t survive without). But many of the microbes that do cause disease have developed the ability to thwart the drugs we use to treat them....

“The health and safety of Fitbit users is our highest priority. We are taking this action out of an abundance of caution for our users,” the Google-owned company said in a consumer notice posted on its website Wednesday. According to the US Consumer Product Safety Commission (CPSC), the issue is caused by the smartwatch model’s lithium-ion battery. While these are incredibly common in electric devices like laptops, TVs, cell phones, and even electric cars, lithium-ion batteries can be fire hazards when improperly handled....

Proton exchange membrane fuel cells are an old idea, and were used on early space exploration missions, though they were later pulled because of weak power generation. The fuel cell runs on hydrogen and oxygen, and it produces water as a byproduct. Fuel cells have been powering experimental airplanes for a little while now, but the technique that would make them economical always seems to be five years away. The design and approach set for the HY4 doesn’t seem to be any different....

Here’s how the researchers describe their system: After the robot scans the package, experts can examine what’s inside, and make a call about whether or not to destroy the suitcase. Having that information is helpful for the actual process of defusing. It also provides a record that experts can then hand off to law enforcement looking to track down bombers. Presently, if a bomb squad wants to look inside a package, they have to have the robot carry it and place it in a mobile x-ray station, which could risk dislodging some part of the bomb in the process....

NIU Kqi3 Pro Electric Scooter, $599.25 (Was $799) This scooter can go up to 20 miles per hour and lasts up to six hours (up to 31 miles) per charge, which makes it perfect for short trips to the store or a joyride around the beach or park. We found the Kqi3 very easy to handle, even for someone who hasn’t used an electric scooter before, and were impressed at how well its beefy tires handled small bumps, rocks, and other obstacles....

Pichai offered some insight into areas that will benefit from the expansion, including Georgia, where the company will open a new office, and Texas and Colorado, where new offices are already underway. Existing offices in New York, Massachusetts, Washington, and Pennsylvania will also receive additional funding, as will data centers in many of those states and others, including California, Iowa, and Nebraska. The focus on improving Google’s physical spaces comes a week after the company began calling some employees back into the office, albeit on modified schedules....

Night vision technology picks up on infrared wavelengths, energy usually emitted in the form of heat that humans can’t see with the naked eye. Researchers have known for years that because of how it conducts electricity, graphene is an excellent infrared detector, and they wanted to see if they could create something less bulky than current night-vision goggles. These goggles rely on cryogenic cooling to reduce the amount of excess heat that might muddle the image....

The reason for such grisly bird murders might be due to a shift in migration and nesting timelines for both birds, according to a new study published Thursday in Current Biology. While great tits typically breed two weeks earlier than pied flycatchers, their breeding periods now occasionally overlap due to climate change-related factors, the authors say. Sara Keen, a behavioral ecologist at Cornell University who wasn’t involved with the new study, says she was really struck by how behavioral changes in response to climate change can manifest in a wide variety of ways, like an uptick in macabre bird murders, for instance....

Stop previews from playing automatically One of viewers’ longest-running criticisms has been the trailers that automatically play when you open the app or hover over a movie or show. No longer: Netflix recently announced users can control whether or not they see these teasers. To turn previews off, sign into Netflix in a web browser, select Manage Profiles from either the “Who’s watching?” screen or the drop-down menu under your avatar (top right)....
