Best printer: Epson EcoTank ET-2400 Every home or office needs an all-in-one printer for when a document needs to be scanned, printed, or copied. This may only happen a handful of times a year (unless the printer is living in a house with school-age kids), but you’re guaranteed to get a “THANK YOU!” text each time it does. We like Epson’s ET-2400 because its ink tanks are more efficient and eco-friendly than disposable ink cartridges....
So goes this excellent review of Halo 4 by friend of PopSci (and, um, roommate of me) Joe Bernstein over at Kill Screen. Read it, it’s the tops.
Capture all the beauty of the sea without worrying about camera damage. The Olympus is waterproof, with five underwater shooting modes including underwater microscope and underwater white balance modes. The camera shoots footage in crisp 4K HD and is designed to work down to 50 feet of water. It’s also perfect for other tough photography adventures, with anti-fog, freeze-proof, and shockproof features. This compact camera is no lightweight. It’s waterproof down to 65 feet, freeze-proof to 14-degrees-Fahrenheit, and shockproof for falls reaching 5....
Why are space watches so popular? Space watches are popular for a few different reasons. When we’re talking about the specific models of wristwatches that have gone into space, those models have a certain cachet: they were durable enough for some of the most extreme environments a human can experience. These watches must be waterproof, airproof, resistant to both extreme heat and extreme cold, and capable of withstanding the bumpiest of landings....
Building your own website gives you a way to own your online identity and, for many, it’s a way to present a portfolio to potential clients or employers or to even start your own business. And long gone are the days when creating a website required technical know-how or design skills. There are a variety of services that allow you to choose from a library of professionally designed templates so that you don’t need to spend time agonizing over design choices or technical questions, with robust options to add every function you might need on your website....
Security is always a work in progress, as designers and engineers respond to new threats online, at home, and on the battlefield. Sometimes that means big, bold efforts like building hypersonic missiles that streak across the sky at five times the speed of sound. But it also means finding ways of filling the small gaps that arise in everyday life, like making it a bit easier to protect our data online or developing an AI-powered security camera that costs just 20 bucks....
Scientists know for certain that all domestic cats are descended from the North African and Near Eastern subspecies of wildcat Felis silvestris lybica, and recent evidence has shown that this domestication occurred probably 10,800 years ago near the Middle East. But new findings suggest that cats were likely domesticated twice–the second time some 5,000 years ago in China, when an altogether different species of wildcat was brought into a then catless human community....
The whirlybird flew at an average speed of some 200 mph for the journey, and had to make a couple fuel stops along the way. “It really behaved flawlessly,” Paul Lemmo, Sikorsky’s president, said. “There were no issues. Fuel burn was less than what we expected.” The helicopter in question is called Defiant, and it’s a unique-looking bird. The most noticeable difference between it and a regular helicopter is the fact that it has two large rotors up top....
For starters, it’s not just grain-free diets that seem to be the problem. To really understand what’s going on here, we first need to talk about general canine nutrition. In recent years, many pet owners seem to have begun to think of grains as filler products in dog food—something our pups don’t need that could harm them. The truth is that grains provide essential nutrients, even protein, and there are very few dogs out there with grain allergies....
Lab: DHS Center of Excellence for Explosives, Mitigation and Response at the University of Rhode Island Career: FBI explosives expert, government defense contractor Car bombs, improvised explosive devices and pipe bombs—for students at the University of Rhode Island’s energetic materials lab, those tools are as common as a hammer is to a carpenter. The lab, run by chemist Jimmie Oxley and supported largely by the Department of Homeland Security, offers the most diverse explosives curriculum in the U....
The loophole was apparently first noticed by TikTok users over the last week, who quickly brought the hack to viewers’ (and, naturally, Spotify’s) attention. The media streaming giant wasted no time in going after the offenders, and have since reportedly shut down at least the first round of pirated films available via the video podcast tool. “IP infringement is an industry-wide issue that we take very seriously. Any content that is provided to Spotify that infringes on third-party rights will be removed,” a spokesperson said in a statement provided to Fast Company, adding that the company “invests heavily in processes to detect and remove such content....
As with any groundbreaking technology, controversy arose, whether it was over a 3-D printed key that can crack open handcuffs or a 3-D printed firearm that could give average Joes on-demand access to guns–no five-day waiting period required. But even the projects that raised ethical questions or exposed our legal framework to gaping gray areas are, in their own ways, technological triumphs–proof of 3-D printing’s vast potential and popular momentum....
To recap: NASA was first put on alert in late August, when flight controllers at Johnson Space Center noticed dropping air pressure in the space station (although the crew was never in any real danger). Astronauts quickly found the leak was coming from a two-millimeter-wide hole in a Russian Soyuz capsule docked to the ISS, which had just brought three astronauts to the space station in June. The crew plugged the hole with epoxy and gauze, which effectively solved the leak, but everyone remained flummoxed as to how it got there in the first place—by all indications, the hole probably wasn’t created by an impact with space junk or micrometeoroids, which left open the possibility it was created by a human....
Scroll through any weightlifting or bodybuilding forum and it’s easy to feel out of the loop. People throw around advice about BCAAs and HMB and various kinds of protein powders like these are things everyone at the gym should know—and use. Even experienced runners and lifters can feel as if they’re doing something wrong by not supplementing. But here’s the truth: most of it is totally unnecessary. You could save yourself time and money by just eating a healthy, balanced diet with enough protein to meet your needs....
Angular momentum is the momentum contained in an object’s rotation. Linear momentum depends on the linear velocity of an object and its mass. However, angular momentum depends not only on the (angular) velocity and the mass of the rotating object, but also on the distribution of that mass. Let’s say you have two wheels of equal mass. If one of the wheels (let’s call it wheel A) has most of the mass distributed towards its circumference, it will have a greater rotational inertia than wheel B, which has more of its mass near the center....
EA unveiled the first gameplay trailer for the upcoming Star Wars title at an event last night and, even with massive hype going in, the video delivered on the promised excitement. From a gameplay standpoint, it offers a single-player campaign in which you can play as a rebel or the empire. The real draw, however, lies with the multiplayer modes. All the multi-player offerings are team-based. There’s a basic five-on-five battle option, but the signature online play mode is more complex....
Every January, fat’s in the crosshairs of health columnists, fitness magazines, and desperate Americans. This year, PopSci looks at the macronutrient beyond its most negative associations. What’s fat good for? How do we get it to go where we want it to? Where does it wander when it’s lost? This, my friends, is Fat Month. Like a nice mutton, your body gets more fatty as it gets older. This is just the unfortunate reality of aging: lean muscle slowly degrades, some of it turning into fat (and some people stop thinking you look tasty)....
But at least one fungus—one resistant to multiple drugs—has begun to adjust to the heat, thanks to climate change, meaning it could potentially thrive in human bodies, making it a serious global public health threat. “As the climate warms, fungi adapt to higher temperatures and some will be able to grow at humans’ temperatures,” said Arturo Casadevall, chair of molecular microbiology and immunology at Johns Hopkins Bloomberg School of Public Health....
It’s a great era to be a motorcyclist. Bikes are faster, more powerful, safer, and more refined than ever. And they come in all shapes and sizes. That means even the gnarliest machines out there can be surprisingly, paradoxically, wonderfully easy to ride—in spite of gaping ram air ducts, huge horsepower numbers, and evil-sounding exhaust notes that would suggest otherwise. However, none of these motorcycles are for beginners. I can’t stress that strongly enough....
Yet some frogs have evolved skulls that look more like crazy dinosaur fossils than your average Kermit. A process called hyperossification allows extra layers of bone to grow on parts of their skulls, creating anything from grooves or ridges to bony spikes or fangs. Researchers have known for a long time about the select groups of amphibians that have these unusual skulls, but it wasn’t previously clear how these subgroups ended up this way....
