Space launches have become so routine these days that they're about as worthy of reporting as a transatlantic passenger plane taking off. However, sometimes mishaps happen and some of these can have major implications. Launched on November 27, 2025, MS-28 was a routine mission to send Roscosmos cosmonauts…...

AutoFlight Aviation Technology is developing a vertiport that's essentially a solar-powered barge that can go where it's needed " water permitting. VTOL air taxis based on a new generation of multi-rotor craft might fulfill the promise of the old helicopter passenger services that emerged in America and Britain in the 1940s and 50s, only to flame out and be reduced to a niche market. Now, AutoFlight is showing off its solution in the form of a self-propelled, solar-powered barge called the Integrated Sea"Air Low-Altitude Economy Solution that can be moved where it is needed on any reasonably sized waterfront. Consisting of a landing pad covered with solar panels and a cabin that doubles as a departure lounge and technical room,…...

Perovskites are inorganic crystalline structures similar to the natural mineral perovskite (calcium titanium oxide, CaTiO3). Halides are binary compounds of halogens (such as fluoride from fluorine, or chloride from chlorine); they're the inorganic salts of halogen acids (such as hydrochloric acid). Previously, scientists faced limits in working with halide perovskites. Light, heat, and moisture make them unstable, and perovskite solar cells generally used lead, famous for causing developmental, neurological, and other damage (and without which, the cells were inefficient). The Cambridge method not only produces better results, but less hassle. "A lot of perovskite research uses solution processing, which is…...

According to the Ministry, the latest tests of DragonFire not only demonstrate its lethality against high-speed targets but also the rapid maturity of the program. Originally slated to see active service in 2032, it will now be installed in the Navy's Type 45 frigates by 2027 as part of the ship's regular armament. In addition to detecting, tracking, and shooting down drones flying at high-subsonic speeds, DragonFire also demonstrated new, advanced capabilities. These include not only the ability to hit a target the size of a "1 coin or US quarter at the distance of a kilometer (0.62 miles), but also a new above-the-horizon targeting capability. Until now DragonFire has…...

This example provides a hot and steamy take on small living with a sauna that seats up to six people. "Aquila is fully off grid, enabling sauna culture to be transported anywhere and for any occasion," explains Out of the Valley. "Made from sustainable materials, its rustic cabin styling keeps it connected to its natural environment, whilst the high quality Narvi stove and alder interiors ensure a premium sauna experience." Its thermal alder and larch interior is insulated with sheep's wool. The layout is arranged over a single level and looks authentic " like a traditional stationary sauna. Bench seating is installed and a wood-fired…...

What they found was that kids who had been exposed to recommended levels of fluoride in drinking water " 0.7 and 1.2 mg/liter between 1962 and 2015, and 0.7 mg/L from 2015 to present " had, on average, higher scores across the board by their final school year. They came out on top in vocabulary, reading and math. The advantage, the researchers noted, continued through life until some participants were aged 60, however, the results were not statistically significant. "It is vitally important for the public " and people who influence public policy " to know that there is absolutely no'credible scientific evidence to support the claim that putting fluoride…...

16+ hour, 42+ min ago (327+ words) While lithium extraction technologies generally focus on ways to get the essential metal out of the ground, there's another source to mine: existing batteries that no longer work. A new technique could now make that process economically viable. Enter the new technique from scientists at the University of Illinois Urbana-Champaign. There, a team led by chemical and biomolecular engineering professor Xiao Su, has been spending time disassembling batteries and then submerging them in an organic solvent. This leads to a brine that contains lithium as well as other metals present in the batteries. To harvest the lithium, the team developed a special electrode created from a copolymer consisting of molecules that attach to lithium and those that respond to an electrical current. When placed inside the brine and electrified, it sucked only lithium from the solution like a sponge, leaving…...

It uses a combination of AI models to make sense of the prompts and generate monochrome outlined illustrations, while a thermal printer spits out the artwork on BPA- and BPS-free paper. That's all there is to it, and it's kind of genius, really. The idea came from Hapiko co-founder Bob Whitney who recently found himself dusting off a desktop printer at home to make coloring pages based on his son's imaginative ideas. The compact Stickerbox " a 3.75-inch (9.5 cm) cube that fits on a child's desk " streamlines that entire process, and puts kids in control of the artistic output. The company says it's committed to…...

1+ day, 3+ hour ago (535+ words) It may surprise some to learn that Polaris has a serious research, development, and testing facility. One that rivals the kinds of equipment and know-how found at many full-scale automotive manufacturers. I got a full tour of the place, along with a dedicated test track that I got to use later. In the wee hours of the morning, I left my home in Wyoming and traveled 900 miles to Wyoming. It was then I learned that there is a town in Minnesota named Wyoming. It's also where Polaris has its headquarters for testing, and it was celebrating the 10th anniversary of the Slingshot three-wheeled autocar. I've driven the Slingshot several times. Back when it had an engine provided by General Motors, and now with an in-house engine made by Polaris. The Slingshot is a fun two-seater with a high-revving engine, tadpole-style three-wheeled…...

1+ day, 3+ hour ago (670+ words) On a remote coral reef near Papua New Guinea, endless streams of bubbles rise from cracks in the seabed into the shallow water, fed by an underground volcanic system. For scientists, this natural phenomenon has become a kind of crystal ball, revealing how our changing oceans will shape the marine life within them. A team led by researchers from the Australian Institute of Marine Science (AIMS) has found that these volcanic bubbles " made up of almost pure carbon dioxide (CO2) " create a kind of localized change in the environment, due to the increased acidification of the water. As the gas rises, it forms visible streams of bubbles, which dissolve into the surrounding seawater and change its chemistry. And because this is occurring near coral reefs in Papua New Guinea's Milne Bay, the scientists are able to see what elevated CO2 in the…...
