A new contender has entered the encapsulated toothpaste market, with a chewable, no-packaging form of toothpaste.Both existing toothpaste pills market themselves as fluoride free, perpetuating anti-science myths.Toothpaste tubes are technically recyclable, but it’s difficult to find facilities and people aren’t recycling them.New Atlas reports that a new contender has entered the “toothpaste capsule” space, with nearly identical ingredients to an existing product—and neither has cavity-fighting fluoride. The new version, a Canadian product called Change Toothpaste, is motivated primarily by a desire to take the packaging waste out of the existing toothpaste market....

On the whole, space is mostly empty, but the space around the Earth is anything but. Earth’s orbit is full of thousands of satellites, pieces of debris, and junk from the thousands of rocket launches over the past few decades. This presents a serious problem for future satellites: Any one of them could be randomly taken out by a flying piece of space junk.The only way to solve this problem is to clean up space, but that’s easier said than done....

The Midwest is full of strange weather, and it’s not uncommon to rain one minute and be sunny the next.

Five years ago, Mercedes-Benz rolled out the CLA, a play to hook younger buyers and turn them into Mercedes drivers via an entry-level Benz in the $30,000 range. It worked. Mercedes sold a ton of them, and now it’s doubling down on the strategy.Here is the 2019 A-Class. Mercedes debuted a European hatchback version in the spring, but revealed this sedan—the version that will go on sale in America later this year—at an event in Brooklyn last night....

American bombs are dropping in Syria. And while the Obama Administration had previously demanded that Bashar al-Assad be removed from power, the Syrian strongman is not the target. Instead, the gun sights are trained on radical Islamic group who have been fighting Assad’s government, especially Islamic State.When those groups were battling it out with Syria, the West let it go. But Islamic State has seized land in Iraq at an alarming rate in an attempt to create a new caliphate from the power vacuum there....

Elon Musk reveals the new Tesla Semi and transport truck.Alexis Georgeson / Tesla MotorsWhen you hear about futuristic driverless tech, you tend to hear about systems built for autonomous cars, like Tesla’s Autopilot or Cadillac’s Super Cruise. But the truth is some of the most important “autonomous” vehicles won’t ride on four wheels. They’ll ride on 18. And for good reason. Tractor trailers move 70 percent of all domestic freight, account for nearly a quarter of all greenhouse emissions in the U....

We’ve seen what North Korea can do, and even though it hasn’t been in the news lately, the experts we consulted say that terrorists are still trying to get dirty bombs into the country. The threat of a nuclear attack on the United States is higher than it’s been since Berlin had a wall down its center. But what would that attack entail? What kind of damage would a nuclear bomb cause, and what, if anything, could we do to get ready for it?...

The U.S. Air Force has awarded contracts to Northrop Grumman and Boeing to build a new long-range intercontinental ballistic missile. This new missile, called the Ground-Based Strategic Deterrent (GBSD), will replace the 45 year old Minuteman III.America’s strategic nuclear arsenal is built on a “triad” model—nuclear warheads are distributed among a force of bombers, ballistic missile submarines, and intercontinental ballistic missiles, each with their advantages and disadvantages. Bombers are slow but can be retasked, have a “man in the loop,” and can be recalled if necessary....

A Nova Scotia man is selling his British Army anti-tank guided missile carrier for the low, low price of $36,000.

Media Platforms Design TeamLAS VEGAS—Who says game night has to be confined to either a physical or digital world, without the ability to switch back and forth between the two?

The videos you shot on the International Space Station caught on like wildfire down here. Why did you start making them, and how did you feel about becoming an astronaut celebrity?I never thought about the second part of that. Truly, I was just living an amazing sequence of adventures and trying to figure out the best way to share them. That didn’t really change from my first two flights. My motivation, my impetus, was the same....

But you may be able to do as well by merely adjusting your current router’s settings....

Media Platforms Design TeamA Harvard research team has confirmed that NASA did indeed discover a new, hot super-Earth back in February. Some 180 light-years away from Earth, HIP 116454b is 2.5 times larger than our own planet and orbits a star smaller than the sun every nine days.This world is too hot for human life, but it’s important nonetheless: Its discovery confirms the success of the NASA K2 mission, a plan to revive the Kepler planet-hunting telescope that had once been written off for dead....

Air traffic controllers have a pretty stressful job. They have to manage dozens or hundreds of planes very quickly, and a single mistake can result in a serious accident or death. But while it’s a stressful job to have, it can be relaxing to listen to.That’s the premise behind the new website Listen To The Clouds, which couples live air traffic chatter with ambient music. The result is some relaxing background noise that you can listen to throughout the day....
