The reason may lie in some of the gyre’s eddies. A study published yesterday in the journal Nature finds that marine predators (tunas, billfishes, and sharks, for example) get together in rotating ocean eddies that spin clockwise and are anticyclonic, or rotating around the center of a high pressure in the reverse direction of a cyclone. The study suggests that the predators are moving with these temporary loops of water as they travel throughout the open ocean and foraging on the biomass (or life) that is within the eddies....

The fact that we haven’t studied that simple, straightforward issue is a testament to how little we study firearms, which the authors write in their research letter published in JAMA. They begin by noting that “Currently, there are no comprehensive assessments of injuries from different types of firearms,” and later note that, even though they were asking a fairly simple research question, their findings were limited by how little data was available about each shooting....

That may be fast, but it’s still nothing next to the lasers some physicists get to play with. Welcome to the world of ultrashort light pulses: little blips of a light wave, lasting as little as a quadrillionth of a second after they leave the laser that makes them. At those timescales, strange things start to happen. For instance, pulses often pop out in pairs, one after the other. Now, physicists at the Universities of Bayreuth and Konstanz in Germany have found they can control the pacing of those duos....

Apple first introduced its “Find My [device]” feature in 2019, which uses location tracking to pinpoint owner’s potentially missing iPhones, iPads, and AirPods. When enabled, Find My can issue a pinging alarm tone to help locate the items if they are connected to WiFi or a cellular network, and sends an alert to users’ Apple ID email address. Users can also pull up the device’s approximate location on their Maps app....

So we asked a few forward-thinking professionals in the business of buildings. The question went something like this: If we were going to remake a famous building or bridge using the materials we have today or will have in the future, what would we do differently? That’s just vague enough to make things interesting. Here’s what we got back. THE GOLDEN GATE BRIDGE, 1937 JEROME LYNCH OF THE UNIVERSITY OF MICHIGAN We’re good at building bridges, for the most part....

The Ring Video Doorbell Pro 2 and Ring Floodlight Cam Wired Pro now include radar sensors inside. According to Ring’s chief product officer, Jason Mitura, the new radar rig consists of two transmitting antennas and four receivers. It works similar to any other radar system you’d find in a self-driving car. “The two transmit antennas send out a chirp—a wave with a distinct pattern,” he explained to PopSci via phone....

Though robots have taken over butchering most of the billions of chickens processed in factories every year, the same hasn’t happened for beef. Butchering cows requires fine-motor skills that robots simply don’t yet have. No two cows are alike, so butchers have to feel the carcass to divvy up the proper cuts of meat. Cutting into the bone can lead to the spread of disease, like Mad Cow; cutting too far from it leaves meat behind, costing the company money....

The 4 foot 9 robot, which weighs in at approximately 148 pounds, has built-in artificial intelligence (AI) that equips it with a variety of skills. Mahru comes with an advanced motion capture system, for instance, which allows it to mimic common actions like arm waving. Like a human, it can also move its lips, eyebrows and pupils, and when it walks, Mahru is able to pull its hands away from any obstacles....

It’s not clear yet exactly what happened to the Zenit-3SL rocket. It was carrying a telecommunications satellite made by Boeing, Intelsat-27, and the launch was organized by Sea Launch, a company owned by a Russian-led consortium that’s headed by another company headquartered in Switzerland. (You can read a semi-vintage 1999 Popular Science article about it here, if you’re so inclined.) Sea Launch has been setting up launches since 2011, after returning from Chapter 11 bankruptcy following another crash in 2007....

“Scientists all over the world are finding microplastics everywhere, everywhere you look,” says Javier Lloret, a marine ecologist at the Marine Biological Laboratory in Woods Hole, Massachusetts, “whether it’s at the bottom of the ocean or the top of the highest mountains, or even if you go to remote areas like the Antarctic.” Despite the ubiquity of microplastics, scientists are still just beginning to comprehend the impacts they may have on our ecosystems, Lloret says....

The new system, which the team purports could be more efficient than existing power-generating systems, is based off of a thermodynamics process described through a closed-loop Brayton cycle, and works similarly to a jet engine. Most jet engines are powered by an open Brayton cycle. Ambient air is brought in and compressed. Then, it’s heated with fuel and expanded through a turbine. That turbine can then mechanically operate a generator to produce electricity (if you’re ground-based), or thrust (if you’re on an aircraft)....

The Galaxy S22 Ultra packs a lot in its slim slab: a “built-in” Samsung S Pen stylus; a 108MP ultrawide back camera that allows you to record in 8K/24fps video, accompanied by a 12MP ultrawide lens, 10MP telephoto lens, and dual 10MP under-camera lenses; plus a 40MP front camera. And, filming is smooth and clear no matter the time of day with Auto Focus Video Stabilization and Night Mode. You have plenty of space for all those Oscar-worthy shots and apps thanks to the 128GB, 256GB, 512GB, and 1TB storage options....

Research conducted by Cornell and Johns Hopkins University researchers has shown that people who are able to handle rejection in the proper manner–by shrugging it off and blazing their own, independent trails–can experience heightened creativity and even commercial success through an ability to eschew mainstream thought and groupthink and instead pursue their own creative solutions to problems. They tested their hypothesis through a series of experiments in which they manipulated the experience of social rejection; subjects in the study were led to believe that everyone in a group exercise could choose whom to work with on a team project, only to be told later that no one had selected them for a team....

The researchers wanted to test two important tools that they suspected might work differently in zero gravity. The first involves moving liquid from one container to another using a pipette—a process that involves suction and usually relies on gravity to keep substances in their beakers. This would be important for preparing DNA for long-term storage, according to the Nature News article, but also for transferring specific amounts of a given solution to dozens of other biology experiments....

Arne Mooers, a professor of biodiversity at Canada’s Simon Fraser University, and colleagues worked for seven years to assess how much evolutionary history a specific bird represents compared to other bird species currently alive. In order to do it, the team developed an evolutionary tree containing all 9,993 known bird species, says Mooers, and then calculated the total amount of time evolutionary processes “worked” to create those species: about 77 billion years....

The animals spend most of their time in water, which sucks heat away from the body about 23 times faster than air. Their North Pacific habitat is impressively chilly, with water temperatures ranging from zero to 15 degrees Celsius (32 to 59 degrees Fahrenheit). Sea otters are also the smallest marine mammals, which means they have a larger surface area relative to their body size through which to lose heat, and they lack the insulating blubber found in their more massive relatives....

What is a private email server? An email server is a data drive that stores your messages before you download them to a client on your computer or a page in a web browser. These servers rely on whichever company provided your email address, so Google runs the Gmail servers, Microsoft takes care of Outlook, and so on. A private email server doesn’t sit in the server farms of Google or Microsoft....
