The Yarrabubba crater’s unimpressive look is hardly surprising; really old craters are rare because Earth’s surface is constantly being reshaped by plate tectonics and erosion. “There’s no longer any kind of crater morphology that we’re used to; there’s no bowl shape or rim of the crater,” says Timmons Erickson, a geologist at the NASA Johnson Space Center in Houston. “It’s all been eroded away.” However, Erickson and his colleagues have found evidence that the Yarrabubba crater was created when a meteorite struck the planet about 2....

Then, it opens its mouth. Yikes. Fang blennies get their name from their distinct twin fangs, which fit securely into slots in their heads when their mouths are closed. Scary enough. But some fang blennies add a little extra juice to their bite. In a paper published Thursday in Current Biology, biologists describe the potent venom of these fish, denizens of coral reefs in Australia and around the world. (Not to be confused with the land-dwelling blenny fish....

The company’s newest partner in this endeavour is called Jaunt, and yesterday they revealed a design for a flying rotorcraft that could one day whisk people around urban areas. Like other concepts and prototypes we’ve already seen in this field, it’s an electric vehicle designed to take off and land vertically, and then cruise horizontally from place to place with passengers onboard. And like others, it has multiple electric motors to do that job....

See, data centers, or buildings where all of the internet is processed use a ton of energy. No, really. In the United States alone, they annually suck up the equivalent of the energy output of 34 coal-fired power plants. A lot of that energy goes to powering the actual servers, but almost half of it goes to keeping the servers nice and cool, so they don’t overheat and crash, sending us all into the apocalypse keeping parts of the internet offline for a while....

But don’t be fooled by the tenderness—that careful touch is meant to handle some extremely hazardous materials. As recently announced by CSU, in combining “soft robotics” with “superomniphobic coatings,” scientists have developed a flexible and lightweight machine whose finger-sized gripper is composed of only a few dollars’ worth of nylon fiber and adhesive tape. Despite the robot’s small size and low cost, the embedded artificial muscle is 100-times stronger than its human counterpoint....

A study appearing in the Journal of Neuroscience suggests that specifically three-dimensional video games can boost performance on memory tests by up to 12 percent. Researchers note that this is typically the percentage of memory function lost between the ages of 45 and 75. “Just by playing a commercial video game and by exploring the world in it, you seem to get better in your ability to learn and remember details of other events,” Craig Stark said, in an email to Popular Science....

Now, Ozempic’s newfound status as a weight loss hack has infiltrated TikTok, which is causing the drug to fly off the shelves. But the increased demand for the injection has also sparked a drug shortage worldwide, leaving people with diabetes without a means to get their prescribed medication. As the trend takes off, multiple health professionals are questioning the safety of using an off-label drug and its long-term effectiveness for keeping the weight off....

Researchers from Sweden and Germany assessed the little animals—segmented, six-legged and often less than a millimeter long—after the European Space Agency shot them into space with the FOTON-M3 mission in September 2007. The brave micro-astronauts returned to earth ten days later, where scientists experimented with reviving them after their exposure to vacuums, oxygen deprivation and bombardment by ultraviolet and other radiation. The results of tests on the critters were just published in the journal Current Biology, around a year after the launch and mission....

While this isn’t the fist dinosaur mummy to be discovered, they are a historically rare find. Typically, fossilized skin forms when the carcass of a dinosaur was protected from becoming a predator’s snack due to a quick burial and/or desiccation. Desiccation is when the moisture is sucked out of the skin of a living organism and deflated is when it shrinks down. Dinosaur “mummies” have well preserved skin like those of this Edmontosaurus, but this specimen was different because of its crocodile wounds....

“We have no clear indications that there is any non-terrestrial explanation for them—but we will go wherever the data takes us,” a senior government official told NBC News in advance. In its statement, the Pentagon avoided outright denying any UFO activity. “Incursions into our training ranges and designated airspace pose safety of flight and operations security concerns, and may pose national security challenges. The Department of Defense takes reports of incursions—by any aerial object, identified or unidentified—very seriously, and investigates each one....

Lifferth’s HB 420 is titled Unmanned Vehicle Amendments, and it wants to give public safety officials the authority to disable or destroy drones that get in the way of emergency response. As written, the authority is pretty narrow, with “acute emergency” defined as “a fire, a flood, extreme weather, a missing person situation, or a natural or man-made disaster that is expected to present an imminent threat to life or property, or to public health, safety, or welfare for more than 24 hours,” and “neutralize” spelled out as forcing termination by disabling or destroying the drone, interfering with it, or taking it over....

Smart displays aren’t particularly new, but Vestaboard’s approach is notably different. Instead of presenting one large digital display, the board is made up of 132 individual “bits,” which flip to reveal different characters and colors. Vestaboard’s founder was inspired by the arrival and departure boards found in European train stations. While the board’s “screen” is completely analog, the inside is totally digital. Once it’s connected to your home network, via Ethernet or Wi-Fi, you can send messages to the board using the Vestaboard app, which will pop up on its display like giant text messages....

Local ecological knowledge is any sort of traditional or Indigenous knowledge that has been passed down through the generations, according to Franciany Braga-Pereira, a PhD candidate in the Department of Ecology and Systematics at the Federal University of Paraíba in Brazil and one of the authors of the study. It is knowledge that has been created through deep familiarity and personal interactions with local ecosystems. Their findings were then contrasted with interviews from 291 local people across 18 different Indigenous and non-Indigenous communities in Brazil and Peru....

According to the NFL, there were 271 documented game-related concussions this past season — the most recorded by the league since 2011. Roughly one-third of those were caused by helmet-to-helmet contact. One of the worst of those hits occurred in January, during a grinding back-and-forth playoff match between Cincinnati Bengals and the Pittsburgh Steelers, a game generally regarded as one of the season’s dirtiest. How dirty? With 22 seconds left in the game, the Steelers’ star wide receiver, Antonio Brown, was mid air, ready to catch a ball that he hoped would put the Steelers within range of a game-winning field goal....

In this work of nonfiction, Mark Vanhoenacker—a pilot who flies the Boeing 787 Dreamliner from London to cities around the world—moves between memories of his childhood in small-town New England and an adult life that encompasses more cities than he ever imagined possible. Each chapter focuses on a particular aspect of city geography or life. In this excerpt from the chapter titled “City of Air,” Vanhoenacker pairs his first flying lesson in Pittsfield, Massachusetts with a flight as a Boeing 747 pilot to Nairobi, Kenya’s mile-high capital....
