Scientists Say They’ve Figured Out What That Golden Orb Found at the Bottom of the Pacific Ocean Actually Was

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech After spending two and half years pondering a “golden orb” found at the bottom of the ocean, scientists have finally figured out what in the thundering typhoons it actually is. The aureate object looked like some sort of alien relic when it was first discovered clinging to a rock over two miles underwater in the Gulf of Alaska, before collapsing into a blob resembling molten leafs of gold when it was recovered. Now, scientists at the National Oceanic and Atmospheric Administration and the Smithsonian Institution reveal that the baffling object is a remnant of what was once a giant anemone — though it took considerable detective work to reach that conclusion. “This turned into a special case that required focused efforts and expertise of several different individuals,” said Allen Collins, a zoologist and director of NOAA Fisheries’ National Systematics Laboratory, in a statement. “This was a complex mystery that required morphological, genetic, deep-sea and bioinformatics expertise to solve.” …

Mathematicians figured out the perfect espresso

Mathematicians figured out the perfect espresso

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. People love a good cup of coffee, but how do you get a perfect brew? Barring philosophical deep dives into the nature of perfection, an international team of mathematicians and environmental scientists believe that it’s entirely possible to calculate the ideal espresso. Not only that, but they now have the formulas to back it up. The math detailed in their study published in the journal Royal Society Open Science is dense. But the short answer is that’s all about puck size. Picture the typical espresso machine at your favorite cafe. The small dish into which your friendly barista tamps coffee grounds is called the puck. After inserting it into the machine, hot water flows through the receptacle and molecularly absorbs the beans’ flavor, hue, and (most importantly) caffeine.  The quality of the final espresso depends on many aspects, including how the grounds are packed, how long water passes through the coffee, and the size of the grounds themselves. It’s …

I finally figured out how to hide YouTube Shorts (and get them back)

I finally figured out how to hide YouTube Shorts (and get them back)

YouTube first introduced short-form videos around the world in 2021, and it didn’t take long for them to become popular. It was clearly a reaction to the popularity of TikTok, which specializes in short-form video, whereas YouTube has videos that are literally hundreds of hours long. So now, when you open your YouTube homepage, you’ll get recommended a variety of long-form videos in 16:9 format alongside several short-form videos in vertical format, perfect for consuming in quick bursts on your phone. The mix works for some people, but others miss the way YouTube started pushing Shorts so aggressively. There are ways to get rid of Shorts…and ways to get them back when you miss them. YouTube offers few official options for getting rid of Shorts And getting them back is even harder YouTube does not offer any official way to completely get rid of Shorts. The only option is to go to the first row of Shorts you see on your homepage, click the three dots in the upper right-hand corner, and hit “See Fewer …

Protesters Have Figured Out They Can Block Waymos and Berate Their Passengers While the Cars Are Paralyzed

Protesters Have Figured Out They Can Block Waymos and Berate Their Passengers While the Cars Are Paralyzed

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech Tech boosters might love them, but Waymo’s self-driving cars aren’t exactly currying favor with John Q Public. In the past few months, the company’s robotaxis have blocked first responders, drained government resources, and killed beloved pets. It might be a different story if they were publicly owned and operated, but Waymo — a subsidiary of Google’s parent company, Alphabet — is a for-profit entity, giving the whole operation an insidious optics problem. Doug Fulop, a tech industry worker in the San Francisco bay area, is one of Waymo’s aforementioned boosters. In January, he met one of the company’s detractors head-on — through the windshield of one of the robotaxis. According to the New York Times, Fulop and two passengers were inside a Waymo one January night when they were beset by an irate protestor, who proceeded to punch the robotaxi’s windows and berate the riders with death threats for six minutes. Waymo cabs are programmed to stop dead …

SpaceX Veteran Says He’s Figured Out How to Make Rocket Fuel From Water

SpaceX Veteran Says He’s Figured Out How to Make Rocket Fuel From Water

The idea of using in-situ resources, such as water, on the surface of distant worlds to synthesize rocket fuel has been around for many decades. For many years, for instance, scientists have suggested using frozen water on the Moon to ensure future space travelers have a way to make the journey back home. Now, as Wired reports, former SpaceX engineer Halen Mattison and his startup, General Galactic, are looking to put the concept to the test once and for all. The company is planning to launch a 1,100-pound satellite on a Falcon 9 rocket in October as part of an audacious proof of concept. The goal is to test water as the fuel for both electrical and chemical propulsion, processes that involve shooting out a stream of plasma with the use of a magnetic field and burning fuel at high temperature and pressure to generate thrust, respectively. In the case of chemical propulsion, General Galactic is planning to split hydrogen and oxygen in the water via electrolysis, and then burn the hydrogen gas with oxygen …

Scientists Figured Out the Problem With Johnson & Johnson’s COVID Vaccine

Scientists Figured Out the Problem With Johnson & Johnson’s COVID Vaccine

In 2021, just months after the first COVID vaccines debuted, concern was growing about an exceedingly rare but sometimes deadly outcome of certain shots. Two related vaccines—one from AstraZeneca and the other from Johnson & Johnson—were linked to dangerous blood clotting. Out of almost 19 million doses of Johnson & Johnson’s version given in the United States during the first two years of the pandemic, at least 60 such cases were identified. Nine of them were fatal. In the United Kingdom, where almost 50 million doses of the AstraZeneca shot were given, 455 cases occurred; 81 people died. In Germany, at least 71 cases were identified, also linked to AstraZeneca. By late spring, use of both the AstraZeneca and the Johnson & Johnson vaccine was paused, and ultimately both were pulled from the market. But the mystery surrounding the rare blood clotting caused by these vaccines lingered. Now researchers believe they have cracked the case. They have hard evidence for how the blood clotting happened, and they believe that their findings could help make similar …
