This is the first study to look at cat attachment by looking at bonding styles, the same way researchers study dogs and human babies, says Kristyn Vitale, who researches cat behavior at Oregon State University. Studying these loyalty methods in animals can show us how similar our bonds with our pets are to those with other humans. Both babies and dogs display the same basic attachment styles—secure or one of two types of insecure attachment—although they manifest differently in different species, Vitale says....

Shortly after the test, North Korea’s English language news service released a statement claiming it was the country’s first successful test of a hydrogen bomb. Worst case scenario, that means North Korea has a smaller, weaker version of a weapon the United States first tested in 1952, and without the means to launch it–it’s even less likely that they have that. Nuclear tests are detected in stages. Seismographs are the first to pick up on the tests, as they read the force of the blast almost immediately....

Earlier this month, the Camera and Imaging Products Association released its annual report regarding digital camera sales, which includes stats from 2018 and predictions for 2019. The results were tough. Overall, the numbers show a nearly 23 percent drop in total cameras shipped, with attached-lens cameras like small compacts taking the brunt of the losses. The forecast for 2019 also predicts losses, but it’s not all doom and gloom....

That’s a lot to handle. The news is already proliferating, and people are wondering if this will be a piece of chocolate/peanut butter goodness or a complete wreck, even though there aren’t a lot of details on what the film is going to look like yet. (Expect intense speculation on that soon.) George Lucas is staying on board as a “creative consult,” but there’s no telling how much sway he’ll continue to have over his creation....

By the mid-’50s, the experience of exploring the deep in this way was still quite uncommon, but ingenious DIYers wanted in on the action. Pfister described underwater diving as “a brand-new sensation, a feeling of really being out of this world.” In 23 photographed steps, he explained how to repurpose then-ordinary items like surplus CO2 tanks, high-pressure connectors from oxygen-therapy-equipment dealers, and aluminum sheets to build an aqualung—all for about $40 (about $438 in 2022 money)....

Chloroquine and hydroxychloroquine, a closely related drug, “seem to suppress the growth of coronavirus in laboratory studies—in test tubes, so to speak,” says David Juurlink, the head of clinical pharmacology and toxicology at the Sunnybrook Health Sciences Center in Toronto, Canada. “Whether or not they do anything of value for people infected with the coronavirus is not at all clear.” That is, just because something works in a very specific lab setting doesn’t always mean it will work in the human body in the same way....

That’s because the Wrangler 4xe (pronounced ‘four by e’) carries a 400-volt, 17-kilowatt-hour, 96-cell battery pack amidships, which packs enough juice for about 22 miles of silent running on electric power. As a plug-in hybrid-electric vehicle, the Wrangler 4xe also has a turbocharged, direct-injected 2.0-liter four-cylinder engine that provides 370 miles of total driving range, so there’s no electric range anxiety here. They don’t say exactly how many 4xe Wranglers they are selling, but Jeep executives do claim that this plug-in off-roader is actually the best-selling plug-in hybrid electric in the country, so it has obviously found an audience....

Dubuc is set to make a four-seat all-electric supercar called the Tomahawk in North America. Its rounded, sporty design is noted for being an “American look,” and it’s got scissor doors for maximum super car cred. Dubuc engineers are aiming for a 160 mph top speed, a 0-60 mph time of about 3 seconds, and a range of 300 miles or so. There’s not much power train detail on the web site, though we do know that there will be two electric motors, one front and one rear, giving it a sporty all-wheel drive function....

Worldwide, more than 130 million ebikes will be sold from 2020 to 2023, representing a value of $20 billion, according to a new report from the Technology, Media, and Telecommunications practice at Deloitte. The consulting and advisory firm also predicts that annual global ebike sales will reach 40 million units in 2023, far eclipsing the 12 million electric automobiles and trucks Deloitte is forecasting to be sold in 2025. Deloitte attributed the aggressive ebike growth forecast to recent strides in lithium-ion battery (LIB) technology, pricing, and power in the ebike market....

Researchers at the University of Pisa in Italy discovered in controlled experiments conducted in the coral reefs of Mexico, Indonesia, Thailand and Egypt that even in small amounts, the ultraviolet filters in lotions caused the coral to discharge large amounts of coral mucus, a sign of environmental stress, and to eventually bleach. The research also indicated elevated virus levels in the seawater, suggesting that sunscreens may induce latent viral infections in coral....

While studying gelatin, Damodaran realized that its protein is similar to the one that keeps the lowly snow flea from freezing in Arctic temperatures. To isolate the molecule involved, he mixed the gelatin with papaya enzymes, which are excellent at freeing proteins from other cellular material, and separated all the protein chunks by size. Then he mixed each batch with ice cream. The final step was to subject the dessert to a series of temperature changes until he found the one that remained ice-crystal-free....

Cross that finish line with C25K 5K Trainer The app stores are awash with running apps, but C25K 5K Trainer is a fantastic pick if you’re starting from zero (or close to zero). No matter how much you worked out in 2019, this app aims to get you ready for a 5K run in eight weeks through a series of activities and other exercises that gradually get more intense. Starting is quick and easy, and you can map out your runs inside the app as you go....

The pair of fertilized eggs came from a Chinese couple, and the woman gave birth to seemingly healthy twin girls. Rather than a typical genomic mix from the mom and dad, the babies were born with an alteration to a gene called CCR5, making it non-functional. Research shows that people without well working copies of CCR5 are either immune or resistant to HIV. The researchers’ goal for the trial was just that: To make babies who would never get HIV, the virus that leads to AIDS....

But cooking outdoors fills plenty of folks with anxiety. After all, it’s quite different from cooking in a fully-stocked and well-equipped kitchen. Fortunately, there are plenty of ways to make your next meal at the campground less stressful and more satisfying. It just requires more preparation, organization, and the right ingredients. The classically-trained chef also recommends limiting recipes to those requiring 10 ingredients or less, and cooking times shorter than 30 minutes....

The Icona vehicles will join Ferrari’s existing lineup of exclusive, limited-edition, incredibly expensive cars. With names like F40, F50, Enzo, and LaFerrari, these cars — really, more engineering works of art — sell out instantly. And, unlike basically every other car in the world, they go up in value when they drive off the lot. Then there’s the more “standard” vehicles like the 488 GTB, the GTC4Lusso, and the Portofino....

Most years, the majority of people in the U.S. fail to get vaccinated for the flu. Rates have hovered just above 40 percent for years, but for the 2017-18 season only 37.1 percent got the shot. Alicia Fry, chief of epidemiology and prevention in CDC’s influenza division, told The Washington Post that this unusually low coverage might have contributed to the severity. But while 37.1 percent is a paltry number across the entire population, the story changes a bit when you break it down by age group....

This is easiest to understand with an example. You’ve probably noticed that when you copy and paste a URL after following it from social media or an email newsletter, there’s often a lot of extra bits tacked on the end. Take this link to our story on sharks learning to love coastal cities. The URL that was posted to Facebook was: https://www.popsci.com/environment/sharks-near-coastal-cities/. However, the actual URL when I clicked it on Facebook was: https://www....

Such were the high and low points of last night’s game between the San Diego Chargers and the Oakland Raiders — the first NFL game to be shot and broadcast live in 3D. Though there were some glitches, it went pretty well for an experiment that had never been tried before. “This is an alpha test,” said Peter Shapiro, a co-founder of 3ality Digital, the game’s broadcaster. “It may not be perfect, but we hope to change the game....
