Ukraine just struck deep into Russia, destroying a key electronics factory in Cheboksary that powers Putin’s missiles, drones, and glide bombs. With only two stealth drones, Ukraine crippled a plant essential to Russia’s war machine—impacting everything from missile guidance systems to nuclear sub components. As smoke rises, Ukraine’s message is clear: nowhere is safe.

YouTuber and US inventor Styropyro has assembled and tested a 250-watt handheld laser. VIDEO: https://www.youtube.com/watch?v=UBVlL0FNbSE According to him, the laser system he created is 50 thousand times more powerful than laser pointers. Probably, his laser is much more powerful than it can be allowed by american law. This, however, did not stop Styropyro from testing its own development. In a video of the results of field tests, the YouTuber burned several objects and even left burn marks on diamonds. The most common type of handheld lasers are laser pointers, which are mainly used in educational institutions. The power of their...

Freeport, New York — At eWorks in Freeport, New York, piles of dusty televisions, personal computers, printers and other old tech are the start of an electronic treasure hunt. "There is a value that would be there," eWorks CEO Mark Wilkins told CBS News. "Maybe it's a small value, but it's our job to really go through that process and evaluate each one of those components." Wilkins' team first tests to see if electronics still work. If not, they are disassembled, because anything with a chip can contain gold, and more than you might think. And it's not just the...

The United States and Russia exchanged prisoners in Abu Dhabi on Thursday, as Washington and Moscow edge toward a diplomatic rapprochement. Russia released Ksenia Karelina, a U.S.-Russian dual national, who was found guilty in Russia for donating a small sum to a U.S.-based Ukrainian charity and was sentenced to 12 years in prison. Karelina, a former ballet dancer, became a U.S. citizen in 2021 after marrying an American and moving to Los Angeles. In exchange, the U.S. freed Artur Petrov, a German-Russian dual citizen who was arrested in 2023 in Cyprus at the request of U.S. authorities for allegedly exporting...

Russian-American ballerina Ksenia Karelina was released from Kremlin custody in a prisoner swap with the United States on Thursday morning. Karelina was freed in exchange for German-Russian Arthur Petrov at a swap in Abu Dhabi, the Wall Street Journal reported. “American Ksenia Karelina is on a plane back home to the United States,” Secretary of State Marco Rubio said. “She was wrongfully detained by Russia for over a year and President Trump secured her release. @POTUS will continue to work for the release of ALL Americans,” he added. The dual-citizen spa worker was accused of treason against the Russian government...

A major lithium deposit discovered near the Portuguese border in Castilla Leon could power Spain’s energy future. Found within the Conchas Project by Berkeley Energy, the 31 square kilometre site has been hailed financially as a highly significant resource that, if mined efficiently, could meet Spain’s lithium needs, reducing the country’s reliance on imports. Currently, most of the lithium Spanish battery manufacturers use comes from South America. The project, which is still in feasibility studies, promises significant economic growth for the region but faces hurdles. Environmental groups warn that extraction could harm water resources and biodiversity, and they are calling...

The mysterious duo who were pulled over in Coventry, Vt. in the deadly shootout are leftist trans militants with alleged ties to a trans terror cell allegedly involved in three other homicides. On Inauguration Day, the shocking news that a US Border Patrol officer had been shot dead near the Canadian border in Vermont in an incident involving a now-deceased foreign national was overshadowed by coverage of Donald Trump's events in the nation's capital. One week later, a 21-year-old Washington woman was charged over the deadly incident, but little has been reported about her and her deceased accomplice, a German...

U.S. — The general public was finally able to breathe a sigh of relief this weekend due to knowing that, with the TikTok ban, Americans were now only being spied on by the Pentagon, Google, Facebook, Apple, Samsung, their doorbells, and toasters. The U.S. Supreme Court upheld the ban on TikTok that was poised to take effect soon, which would officially shut down the social media platform that had been widely criticized as being a tool for surveillance and data collection by the Chinese Communist Party, leaving just every other major tech corporation, government entity, and smart household device to...

In metals, electrons are normally expected to be diffusive in their movement, operating as individual particles – in other words, they don't gain momentum as a group. In a new study, scientists have now discovered a type of metal where electrons actually do flow in a fluid-like way – like water in a pipe – by interacting with quasiparticles called phonons, which emerge from vibrations in a crystal structure. This causes the electrons to shift from diffusive (particle-like) to hydrodynamic (fluid-like) behavior in their movement. The metal superconductor that causes this behavior is a synthesis of niobium and germanium called...

LOOMIS DAY | May 30 Each year on May 30th, Loomis Day recognizes the man who received the patent for wireless telegraphy in 1872. The Washington, D.C. dentist, Mahlon Loomis, received US patent number 129,971titled “An Improvement in Telegraphing” on wireless telegraphy in July of 1872 beating Guglielmo Marconi's United Kingdom patent by nearly 25 years. #LoomisDay Born on July 21, 1826, Loomis was also the inventor of artificial teeth and one of the earliest inventors of wireless communication. Loomis died on October 13, 1886. Leading up to his patent, Loomis conducted many experiments in electricity using kites flying miles...

Reading for fun sharply declines around age nine in an alarming trend that coincides with years of learning loss since the pandemic, data shows. Only 35% of nine-year-olds are reading at least five days a week compared to 57% of eight-year-olds, according to the latest Scholastic survey on the issue. “The number of kids who say they love reading drops significantly from 40% among eight-year-olds to 28% among nine-year-olds,” the Scholastic report notes. The trend, dubbed the “decline by nine” has concerned researchers, who note that reaching reading proficiency by third grade is a good predictor of academic success. [snip]...

Being proved right isn't always fun. Just weeks after my warning in the March issue that our modern high-tech cars are tracking us and sharing data with manufacturers, cops, and parties unknown, came a report of soaring auto insurance premiums because of snitching vehicles. The consequences get worse from there. Fortunately, there are ways to keep your snoopy ride from contacting the mothership. Your Driving History May Be Transmitted and Stored "Car companies are collecting information directly from internet-connected vehicles for use by the insurance industry," Kashmir Hill reported this month for The New York Times. "Sometimes this is happening...

Hidden cameras are being found in hotel rooms, house rentals, cruise ships, and even airplane bathrooms, leaving many travelers to wonder: “Could a hidden camera be watching me?” Spycams, as they’re called, are getting smaller, harder to find and easier to buy. From alarm clocks to air fresheners, water bottles and toothbrush holders, cameras come embedded in common household items that seamlessly blend with home decor. They can be purchased in shops or online, and through retailers like Amazon and Walmart. And rather than having to retrieve the camera to obtain the recording, owners can stream live images straight to...

I've built power supplies using full wave rectifiers in the past, and a couple circuits with single diode half wave rectification for non-critical supplies, but in all cases the power requirements were low and the diodes I had on hand several times overrated for the current and voltage / power involved.This time though, I want to add a half power function to a 1500 watt 120 volt quartz heater. (Over-simplification - see below comments. But ~half of the 1500 watts is the design target.)*So... I know a diode in series with the quartz element and no power supply capacitor** will...

About 3 million Americans live with cardiovascular pacemakers. But over time, scar tissue or blood clots can form around the leads, or wires, that carry the electrical impulses from the pacemaker to the heart. Scar tissue or clots may hinder the flow of blood, potentially resulting in swollen extremities or pain. However, the incidence and clinical impact of such lead-related venous obstruction, or LRVO, among patients with pacemaker devices is not well characterized. Physician-researchers found that the incidence of symptomatic LRVO among patients implanted with cardiovascular implantable electronic devices to be four times higher than previously reported—with only a minority...

The germanium-tin processor was fabricated at the Helmholtz Nano Facility, the Helmholtz Association's central technology platform for the manufacturing of nanostructures and circuits. Credit: Forschungszentrum Juelich Scientists at Forschungszentrum Jülich have fabricated a new type of transistor from a germanium–tin alloy that has several advantages over conventional switching elements. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation. The transistor thus appears to be a promising candidate for future low-power, high-performance chips, and possibly also for the development of future of quantum computers. Over the past 70 years, the number...

The week of last Thanksgiving, Michael Larkin, a business owner in Hamilton, Ohio, picked up his phone and answered a call. It was the local police, and they wanted footage from Larkin’s front door camera. Larkin had a Ring video doorbell, one of the more than 10 million Americans with the Amazon-owned product installed at their front doors. His doorbell was among 21 Ring cameras in and around his home and business, picking up footage of Larkin, neighbors, customers and anyone else near his house. The police said they were conducting a drug-related investigation on a neighbor, and they wanted...
