To counter this massive artillery fire, Ukraine has asked allies to supply it with modern artillery systems that can shoot and scoot—in other words, fire the munition from a vehicle and then drive away before the shell has even hit its target. That makes it very hard for the enemy to counter-attack, because by the time it has worked out where the shell was fired from, the gunners have scampered....

The drugs used to treat Alzheimer’s today work to alleviate symptoms without slowing the actual progression of disease—drugs like cholinesterase inhibitors, for example, work to preserve memory functions while decreasing mood symptoms like depression and apathy. Aduhelm is different in that it is the first Alzheimer’s drug to target the believed biological pathways that cause the condition. It targets and clears beta-amyloid, toxic proteins that build up and form sticky plaques in the brains of those with Alzheimer’s....

Previous genetic studies of dog lineages have concluded that domestication occurred in Southern China around 16,500 years ago, but the earliest archaeological evidence of domesticated canines is found in Europe and Siberia. All of this contrasting evidence has understandably created not a small amount of debate, but one thing that can be agreed upon is that all dogs came from Eurasian gray wolves at least 15,000 years ago. One key factor was largely neglected in previous studies, however....

Folman’s work earned the Golden Globe award for best foreign film over the weekend, and has also scooped up best picture from the National Society of Film Critics. Film reviewers have praised the animated effort for its surreal, searing depiction of the director’s repressed wartime recollections. It also cost just $2 million to make—a far cry from the $100 million budgets for CGI behemoths such as Pixar’s WALL-E. Unlike films such as Waking Life and A Scanner Darkly, which used the technique of rotoscoping to draw on top of live footage, Waltz With Bashir relied on animation drawn from scratch....

A device like the Pixel Slate is the perfect candidate to take that relationship to the next step. When you’re holding the tablet without its keyboard, the hardware itself to the Android selections found in the Google Play store. At the same time, the beautiful 12.3-inch screen demands a full version of Google Chrome that displays complete versions of websites rather than nerfing them down to the smushed mobile versions....

What happened? First, it’s important to know what was supposed to happen. Scientists would open a borehole with the drill, giving them enough time to lower remote-control probes into the depths. Those probes would search for life. All of this would’ve taken a mere six days. But there were complications. The drill, meant to dive straight down, leaked hot water into the ice well before its destination–just 300 meters under the surface, or about 10 percent of the way to Lake Ellsworth....

1. Cylinders Combustion needs room to boom. This V-8 has 426 cubic inches of cylinder space (a metric known as displacement). It’s not the biggest engine in the world—or even in Dodge’s lineup—but it’s strong, which is crucial when supercharging. 2. Supercharger More oxygen in the engine equals more explosive power. A massive 3-liter supercharger forces more air into the belly of the monstrous beast. It generates 15 pounds per square inch of boost, providing extra ­giddyup the second you tap the gas....

No space agency has ever sent a spacecraft so close to the sun before. Previous attempts have inched as near as 25 million miles from the surface, but Parker Solar Probe will orbit the sun at an average distance of only 4 million miles. In order to do this and not melt into a gooey pile of metal, it is equipped with a revolutionary heat shield. The surface of the sun averages around 10,000 degrees Fahrenheit, but Parker Solar Probe won’t get that close....

This story originally featured on The Conversation. As experts warn that the world is running out of time to head off severe climate change, discussions of what the U.S. should do about it are split into opposing camps. The scientific-environmental perspective says global warming will cause the planet severe harm without action to slow fossil fuel burning. Those who reject mainstream climate science insist either that warming is not occurring or that it’s not clear human actions are driving it....

According to an announcement earlier this week via the University of Central Florida, a team from the school’s Department of Mechanical and Aerospace Engineering developed a new construction material composed partly of lunar regolith—the loose rocks, dust, and other debris covering the Moon’s surface. Using both 3D printing and a method called binder jet technology (BJT) in which a liquid binding agent (in this case saltwater) is infused into a bed of moon powder supplied by UCF’s Exolith Lab, Associate Professor Ranajay Ghosh’s group was able to produce bricks capable of withstanding pressure of up to 250 million times greater than our own atmosphere....

One of the hallmarks of dementia is cognitive decline. There are several lifestyle changes that may slow cognitive decline, such as doing mentally stimulating activities (crossword puzzles, learning a new language), getting plenty of exercise and maintaining a healthy diet—especially one low in saturated fats, refined carbohydrates, and sugar. Of these, diet is a favourite among health reporters, perhaps because the message can be delivered clearly and succinctly. The latest such story comes from the Daily Mirror which claims that eating just two teaspoons of nuts a day “boosts brain function by 60%....

And while there are standard recommendations, coffee making is really all about personal taste. For example, I (a coffee enthusiast, clearly) prefer the pour-over method and use a Chemex to brew my coffee. But that’s just one way to get a pitch-perfect cuppa. During my college barista years, I picked up some tips of the trade—and worked with some quality gear—that I still use daily. Read on.

The stealthy, semisubmersible ship is designed to move agilely around a battle zone and remain flexible in any type of mission, says Mark Steel, a manager of the Combat Systems Team at BMT Defence Services, a naval design firm involved in the project. The battleship could function with a crew as small as 50, as opposed to the usual 200. It would serve as a mobile command center, unleashing and directing armies of drones, missiles, and rovers....

The COVID-19 pandemic has held an extra layer of uncertainty for immunocompromised people, who in some cases face an increased risk of contracting severe disease. As the Washington Post recently reported, researchers are also concerned about whether vaccines offer sufficient protection for certain immunocompromised people, like transplant recipients and people with blood cancers—leaving them potentially at-risk for a serious case of COVID-19 as the CDC’s new unmasking guidelines come into effect....

It took 30 days for COVID-19 to spread from a single province in China to the entire country. The virus is now spreading to dozens of other nations around the world, and the rate of growth has a lot of folks worried. It’s only making matters worse that there’s a lack of good data on this new disease—people have questions, and often public health officials don’t yet have the answers....

Or, in layperson’s terms, the Barrette Bot… or, rather, two Barrette Bots: Using what team leads Zechen Xiong, Yufeng Su, and Hod Lipson dubbed their Hair Clip Mechanism (HCM), the group developed a pair of small, soft robots that utilize strips of prestressed plastic that is then attached to basic electric servos. When activated, the strips alternate between convex and concave shapes, thus enabling movement while simultaneously amplifying the force behind them....
