On the Taylor Glacier in Antarctica, there’s a glacier gushing water the color of blood. The oddity, first discovered in 1911, was understandably named Blood Falls. What makes it happen? Scientists have now mapped the glacier’s innards, allowing for a clear scientific explanation of the seemingly biblical phenomena.There’s always been a rough understanding of how Blood Falls works: The water is loaded up with iron oxide, the same as rust. Previous studies, like one in 2015, hinted that Blood Falls might be aberration stemming from unseen underwater network....

We’ll update with information as it becomes available.Original post: On November 21, the last day of the Los Angeles Auto Show, Tesla will unveil its long-anticipated pickup truck. CEO Elon Musk announced the event on Twitter last week, indicating that it will take place near his SpaceX factory in Los Angeles....

The Hubble Telescope’s spiritual successor, the James Webb Space Telescope, is now slated or a 2019 launch. The Webb will mainly be looking at the Universe in infrared with a larger mirror than Hubble, meaning that it will be able to collect more light. More light means its will be able to look further back in time. But before any of that can happen, NASA’s still got to put the thing together....

Media Platforms Design TeamThese days, the T-90 battle tank isn’t exactly the belle of ball when it comes to Russian heavy armor. The third-generation battle tank is likely on the way out, with the fifth-generation T-14 Armata now the crown jewel of Russia’s rolling thunder.Still, watching the T-90 pull off a move like the one seen above, it’s hard not to admire it.View full post on YoutubeBy the way, if you’re wondering why the camera shakes so much it’s not because of the tank hitting the ground....

On May 22, NASA photographer Bill Ingalls set up his Canon camera to capture footage of the launch of a SpaceX Falcon 9. He got the shot, sort of, but not before that very launch ignited a small brush fire that did the poor camera in for good. Although this martyr of rocket photography has closed its shutter for the very last time, we’re all fortunate enough to be able to see the footage it died to bring us....

Methane is a colorless, odorless, and highly flammable gas, and the main component in natural gas, which is used to generate electricity and heat homes around the world.Methane accounted for roughly 10 percent of all human-driven greenhouse gas emissions in the U.S. in 2017, according to the EPA.The EPA announced in August 2019 that it would roll back regulations on methane gas.Last year, the Environmental Protection Agency (EPA) announced it would begin to roll back Obama-era regulations on methane, a powerful greenhouse gas....

Tonight, Amazing Grace—a documentary film about Aretha Franklin’s two-night performance January 1972, which turned into one of the best-selling gospel albums of all time—makes its long-awaited debut with screenings at the DOC NYC festival.Although the 46-year delay was due in part to negotiation issues with Franklin herself, there was another reason entirely that a documentary shot by legendary director Sydney Pollack took so long to appear: The audio wasn’t synced correctly....

The tomb of King Tutankhamen was found in Luxor, Egypt in 1922, putting to rest the mystery of the boy king’s final resting place. But preliminary results of an ultrasound investigation of the tomb show that it may be hiding other secrets – including rooms behind Tut’s burial chamber. No one is for sure what – if anything – is hiding behind those walls, but many archaeologists are suggesting it could be the final resting place of Queen Nefertiti....

The USS Zumwalt and her two sister ships are undergoing a dramatic change of mission just three years after the first ship was commissioned. The destroyers, originally meant to provide naval gunfire support for the Marines and bombard targets far inland, are now being reorientated to a ship-killer role. The Zumwalt-class of destroyers was meant to dramatically boost the fleet’s gun firepower. After the retirement of the four Iowa-class battleships in the early 1990s, the service studied a number of solutions before deciding on the Zumwalts....

As I waited for the lights to dim at the screening of Blade Runner 2049, I literally had my arms crossed. “Why are they doing this?” I called to whomever was listening. “Blade Runner is perfect, leave it the hell alone! Nobody asked for a sequel.” Five minutes in, and I realized that this, if nothing else, did feel a lot like Blade Runner.By the end of the picture I knew I’d seen one of the best movies of the year....

Lets start at the front of the car and move to the back. Can you talk a little bit about the hood and lights?Im a big believer that vehicles have faces. The Vipers eyes have been kind of these horizontal slits for a long time with multiple headlamp projectors in them. This time around we went to single projector and literally styled the eyes of the car around a snakea little bit more vertically oriented, with a little hood over the projector....

Always looking to take the next technological leap, the Dubai Police have announced their intent to use hoverbikes. The futuristic move is in line with developments across the local Dubai government, which has aggressively adopted expensive, unproven, but sci-fi technologies.View full post on FacebookThe hoverbikes, as seen in a Facebook video distributed by Gulf News, appear to be Scorpion-3s built by the Russian company Hoversurf. On its website, however, the company does not advertise the Scorpion-3 to law enforcement, saying that “for the moment, [the] SCORPION platform is increasingly seen as an extreme sports instrument, yet the vessel’s transportation potential remains evident....

Media Platforms Design TeamFord Mustang GT: Dealers will give you a choice, either the Mustang with its 210-hp V6 or the GT with its 300-hp V8. Guess which one we chose? For straight-up, bang-for-the-buck performance, the Mustang beats the Corvette for the gold. It may not be as fast as the Chevy or as capable around a racetrack, but it’s too much fun to drive to care about those minor shortcomings....

There’s nothing too exotic about the Honda CRF50F. It’s got a 49-cc four-stroke, a kick-starter, and a three-speed sequential transmission. My kids have a friend who has a 2005 model, and that one looks almost identical to a 2019. “These things are bulletproof,” the Honda dealer told me. “I could take it up on the roof of the building and throw it off and it would fire right up.” Well, perhaps that’s a bit of dealer hyperbole, but not by much....

Night is falling, and we’re lost. Somewhere in the canyon lands of southern Utah, I’m trudging across a seemingly endless sagebrush plain, and the twilight gloom is thick. My group of 14 hikers has been on the trail for 5 hours, and our delight at the majesty of the red rock landscape has long since given way to grumbling about hunger and sore feet. As the first stars start to twinkle, the question arises, “Okay, now what?...

In the Sawtooth Mountains of central Idaho, 1,416 square miles (3,668 square kilometers) of land has been named the country’s first International Dark Sky Reserve by the International Dark-Sky Association (IDA), the leading organization that fights against the light pollution that slowly swallows our view of the universe. The Gold-Tier designation, the highest the IDA can award, signifies the quality of the central Idaho’s night sky. The IDA defines a Dark Sky Reserve as having a “‘dark core’ zone surrounded by a populated periphery where policy controls are enacted to protect the darkness of the core....

In a press release last month, defense contractor Lockheed Martin announced that its in-house fusion reactor program could produce a working prototype in as few as five years—and a practical, working system that could take the place of a conventional power plant on the grid within ten years.It’s a bold claim by a single company—one that not even people behind the multinational, multibillion-dollar ITER fusion power research effort in France is making....

Bladeless fans can be a cool little conversation piece and maybe even avert an injury or two if you’ve got some kids around who like sticking their fingers into things. But the famous Dyson variety can cost as much as $400. So why bother with that when you can just make your own out of a a 5 gallon water jug, a plant vase, and some engineering. This simple tutorial from Rulof Maker not only shows you how to make a bladeless fan, but also betrays their greatest secret: There definitely are blades....
