It gives you separate spaces for your music, with its own songs, playlists, and settings. This can be particularly useful if you have a musical taste that ranges over very different and clashing styles, and you don’t want to swing drastically from one to the other when you hit the shuffle button. At the time of writing, Apple Music (the program) has yet to make it over to Windows, but users still have access to iTunes, which also supports multiple music libraries....

“Neutron stars,” writes Jocelyn Read, an astrophysicist at California State University, Fullerton are “the place where matter makes its last stand against the overwhelming force of gravity.” While astronomers can detect neutron stars in a variety of ways, exactly what goes on inside them remains poorly understood. But after decades of research, recent observations and theoretical advances are coming together to suggest that the objects might be in need of rebranding....

This odd feud has now culminated in B.o.B. releasing an explicit “diss track” against Dr. Tyson on SoundCloud, which is full of demonstrably false conspiracy theories, anti-Semitism, and references to holocaust deniers. For those who thought Drake and Meek Mill’s beef wasn’t enough… But let’s back up to where this all began: earlier this week, Bobby Ray Simmons—better known by his rapper name B.o.B—the Atlanta native took to Twitter to begin parroting the completely incorrect and long-ago disproven theory that the Earth is actually flat....

As an astronomer, the question I hear the most is why isn’t Pluto a planet anymore? More than 10 years ago, astronomers famously voted to change Pluto’s classification. But the question still comes up. When I am asked directly if I think Pluto is a planet, I tell everyone my answer is no. It all goes back to the origin of the word “planet.” It comes from the Greek phrase for “wandering stars....

It’s a detail that sticks with people—and that Omega has certainly capitalized on in its marketing—in part because watches are so familiar for the rest of us. And what’s more rugged than a watch that can handle the vacuum of space? The Omega Speedmaster Moonwatch, as it’s now known, remains the only timepiece to meet NASA’s call, in the mid-1960s, for a mechanical chronograph that could endure 12 Gs of acceleration (that’s a lot—here’s what pulling 6 Gs feels like) and temperatures up to 200 degrees Fahrenheit....

Optical illusions are tricks of the light. For example, if you plunge a stick in the water, it will appear crooked because of the way light bends—even though, in reality, the stick is straight. Or, in the desert, when the ground is hot, and air is cool, and there is air turbulence, it might cause a shimmer at the horizon that looks like a pool of water. It’s about physics....

Picture this: While descending a precarious slope, you lose your balance, land awkwardly on a rock, and your foot wrenches sideways. Immediately, you hear a distinct cracking sound—one you’ll probably never be able to forget—and you fall to the ground in pain. What moments ago was a pleasant weekend hike has officially become a lot less enjoyable: you’re in the wilderness with a broken bone. While an injury like this means the end to an excursion, it’s rarely a life-and-death situation....

American chestnut Carpenters once used this hardwood for everything from construction to furniture. That changed in the early 1900s, when a fungus decimated the native population—but you can still find choice boards that have been reclaimed from old buildings or fallen trees. Black cherry Cabinetmakers prize black cherry as one of the finest all-around materials for the job because of its durability and innate beauty. It starts off as a light pinkish color and darkens to a deep reddish-brown over time....

I’m one of those men for whom it is impossible to find Father’s Day gifts. I don’t wear ties. My socks are all the same, in the interest of efficiency. I enjoy cooking, which would seem to open up some possibilities. But I have an annoying habit of buying useful gadgets as I need them, leaving my relatives to purchase paper bags specially designed for storing cheese, say, or devices that carve vegetables into the shape of noodles....

Across the country, buried beneath the pavement you walk on, an invisible network of waterways flows through the darkness. These are ghost streams, and they’re haunting us. In their former lives, they wound through natural landscapes above ground; it’s only through decades of development that humanity has relegated them beneath the earth’s surface, enclosing the waterways in tombs of concrete and iron. The effects, decades later, plague us. Without a natural habitat to snake through, these streams carry downstream an excessive amount of pollutants (like salt and sediment) and nutrients (like nitrogen and phosphorus) because they can’t divest these materials into their surrounding environs....

Below, tricks that’ll make you more secure online—wherever you roam. It seems like barely a week goes by without some data hack or leak hitting the headlines.

Some residents of ­Morocco who live near the Sahara used to spend hours ­every day retrieving ­water by donkey, but a new fog-​­collecting system is changing that. The ­Aqualonis Cloudfisher’s sturdy ­fabric mounts onto frames and can resist ­74-mile-per-hour winds while collecting moisture from the frequent mountain mist. This drips into a 16-mile pipeline, then flows directly into taps in more than 70 homes. Though people have erected similar systems in South America, Aqualonis claims Cloudfisher is the first to withstand stronger gusts....

“By itself, one year’s global temperature is an interesting note. But put in the context of the warming we’ve seen over the last several decades, it’s kind of an exclamation point at the end of a long run of warming,” says Deke Arndt, chief of the monitoring branch of the National Centers for Environmental Information, which undertook the NOAA analysis. Both reports drew from largely the same temperature measurements; however, each organization analyzed them a little differently....

If you don’t own a Pixel, it’s something of a guessing game as to when you’ll actually get Android 12. Your best option is probably to check with the manufacturer of your handset for updates. Samsung and OnePlus have already begun testing beta versions of Android 12, for example, but haven’t given a final release date yet. When Android 12 makes its way to you, there will be plenty to explore....

But just because you can’t avoid mud droplets drying on your shins, or sweating in humid, 90-degree temperatures, doesn’t mean you can’t still stay clean and—relatively—stink-free while enjoying time in nature. Hand sanitizer with at least 60 percent alcohol is effective at killing germs that can live on your paws and make you sick when you touch your food, nose, mouth, or eyes. Use it often, especially after going to the bathroom and before eating....
