Samsung’s sequel, the Galaxy Z Flip4, is a new and improved version of that winning formula. It has a better processor and upgraded cameras. There are new ways to take advantage of the small cover screen that allows for quick actions when the phone is closed. Like its larger counterpart, the Samsung Z Fold4, it’s made with more durable materials and features a redesigned hinge. These are all good things, and they more-or-less justify the Flip4’s flagship-level price tag....

The scam works like this: After establishing a relationship with a victim on dating apps or through social media, the scammer will suggest that they can help the victim make money through cryptocurrency. They’ll use some sort of fake site to secure an initial investment and then let the victim withdraw a profit to further secure their trust. From there, the scammer will convince the victim to invest more—and then more, claiming there is a need for additional funding to cover taxes, fees, or meet a minimum balance....

Schools around the country continue to reopen, with some districts leaning on remote learning while others let kids pack maskless into halls. Seven months into the COVID-19 pandemic, scientists know far more about the novel virus than they did at the start. Even so, there’s still plenty of unknowns, including how readily kids spread COVID, and for how long people remain immune once infected. Uncovering these mysteries will play a crucial role in our ability to return schools, businesses, and our lives to something like normal....

Fast, simple, and secure, you can grab a lifetime subscription to the service for over 90-percent off....

Scientists at Procter and Gamble, for example, are harnessing Kerschmann’s technology to study how bone reacts to various drugs as it grows. Engineers at Sandia National Laboratories are employing the new scope to measure the tiny screws and gears they use to build microscopic robots. “We’d be up a creek without it,” says Christine Miller, a pediatric cardiologist at the University of Rochester. Miller is using the new imaging technique to investigate whether raising blood pressure around embryonic chick hearts can cause congenital heart defects....

In this batch, released today the mysterious bright spots that dot the dwarf planet’s Occator Crater are of course the center of attention. Scientists aren’t sure what the spots are made of, but they could contain water ice and salt. The ongoing investigations from Dawn’s 240-mile orbit, at which it arrived in December, could help shed light on the contents of the crater. “The intricate geometry of the crater interior suggests geologic activity in the recent past,” Ralf Jaumann, planetary scientist and Dawn co-investigator at the German Aerospace Center, said in a press release, “but we will need to complete detailed geologic mapping of the crater in order to test hypotheses for its formation....

“The Chinese government has put in place a system to spy on and gather information about every guest at hotels where Olympic visitors are staying,” said Brownback. With blogging now allowed by the International Olympic Committee, the Chinese may have plenty to monitor. It’s just the latest example of the Chinese government keeping a close eye on the Olympics. Tickets to the opening ceremony are embedded with RFID tags that hold personal information intended to verify the identity of spectator, minimize scalping and keep away protestors....

These collaboration apps don’t just have to be for the workplace, either—you may also find them useful for planning events or sharing information with family and friends. 1. Google Drive It’s no surprise Google makes some of the best web apps in the business, and Google Drive (including Docs, Sheets, and Slides) is just about the best it’s ever built. This suite of apps makes collaboration look easy: Open up a document, spreadsheet, or presentation, and tap the Share button (the portrait icon) at the top....

These little apps can make you more productive, but also keep your computer running faster for longer. Utilities for Windows Take back control of your volume levels with the help of EarTrumpet. This app sits down in the notification area in the bottom right-hand corner of the screen, alongside the standard Windows volume button, and lets you control volume levels for apps independently. This can be useful if you like your music quiet but your movies loud, for example....

Researchers hope it can be a valuable tool to monitor, for example, the opioid crisis. In a new study, rates of tweets about opioids and opioid misuse—analyzed and classified by a machine learning program—matched the rates of opioid overdose deaths in Pennsylvania counties and rates of opioid use measured on national surveys. “The ultimate goal is, of course, to be able to forecast potential crises like the opioid crisis. That is what we are working towards,” wrote study author Abeed Sarker, an assistant professor of biomedical informatics at Emory University School of Medicine, in an email to Popular Science....

The 60-foot-tall “Starhopper,” a partial mockup of the vehicle Elon Musk hopes will one day land on other worlds, soared nearly 500 feet into the Texas sky on Tuesday afternoon. This second and final test flight represents the most significant trial yet of the company’s Raptor engine. While the trial frustrated residents in Boca Chica, many of whom evacuated their homes for safety concerns, it encouraged aerospace enthusiasts with its demonstration of a new type of rocket that runs on methane—an essential feature for a space program targeting the moon and beyond....

Usually when a film wants to have a young actor play an older version of herself, the makeup team leaps in with prosthetics. Even more often, they just cast another actor altogether, someone age-appropriate. But that wasn’t good enough for The Winter Soldier. When prosthetics failed to realistically age Hayley Atwell, who plays Peggy Carter, director Anthony Russo re-shot the scene with Atwell wearing a grey wig and motion capture dots on her face....

We’ve covered the efforts to design machines that scale vertical surfaces using techniques borrowed from geckos, and another that uses vacuum forces. But this weekend, at a major robotics conference, researchers from SRI International will be discussing a different approach: electro-adhesion. The SRI robots can clamp on to glass, wood, brick, concrete and more by using electrostatic charges generated by a battery. The materials used are compliant, so their robots can attach to just about any surface – rough and dusty or clean and flat....

In the study, 153 healthy men and women tracked and reported their sleep volume and quality for 14 consecutive days. At the end of the trial, each participant was quarantined and administered nasal drops containing a rhinovirus. Those participants who had slept less than 7 hours per night were 2.94 times more likely to develop a cold than those who had slept 8 hours or more. As a fitness professional in New York, I have seen first hand the negative effect that little or low-quality sleep has on my clients....

Current airplanes (and, weirdly, some wind turbines) hide their appearance from radar two ways: weird body geometry that reflects radio waves away from their receivers, and materials that absorb the waves, turning them into heat instead of reflecting them back. Seen primarily on modern aircraft like the B-2 Spirit bomber, the F-22 and F-35 fighters, and the experimental unmanned combat drone X-47B, the technology is used by the Pentagon to protect nuclear bombers, spyplanes, and the entire next generation of fighters....

Polyamory literally means to love many, and those that see themselves as polyamorous essentially either are or want to be in a romantic or sexual relationship with more than one person at the same time. It’s not as rare as you might think: Some recent research suggests that more than one in five single adults in America has been in a consensual nonmonogamous (CNM) relationship at some point. Despite that this kind of nontraditional relationship is not exactly rare (and possibly on the rise), the U....

In Asian countries, many people have a convenient tool at their disposal: They’ll often use umbrellas to shield them from the sun’s powerful rays. In the U.S., even though most people own an umbrella to keep dry when it’s raining, almost no one uses it for sun protection. Yet at one time, American women did use umbrellas for sun protection. As a historian of technology, I’m interested in why some technologies are readily accepted by some groups but not others....
