More screen time among children and teens is linked to higher risks of heart and metabolic problems, particularly when combined with insufficient sleep. Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic “fingerprint” in frequent screen users. Experts say better sleep and balanced daily routines can help offset these effects and safeguard lifelong health.

Costco's consistency -- from its $1.50 hot dog and drink combo to its functional shopping carts and satisfied employees -- has produced what The Atlantic calls a "cultlike loyalty" among members at more than 600 locations across the U.S. Its annual membership costs $65. The model traces back to Fedco, a nonprofit wholesale collective for federal employees founded in Los Angeles in the 1940s. Costco's private label Kirkland Signature has... Read more ›

An anonymous reader shares a report: Only the government could spend 20 years creating a national ID that no one wanted and that apparently doesn't even work as a national ID. But that's what the federal government has accomplished with the REAL ID, which the Department of Homeland Security (DHS) now considers unreliable, even though getting one requires providing proof of citizenship or lawful status in the country. In a... Read more ›

A new record-high clock speed has been achieved on AMD's Ryzen 7 9800X3D. The best gaming CPU in the world doesn't need to be overclocked to achieve exceptional performance, but Chinese overclocker "Hero" has just pushed it to 7,335 MHz using a Colorful iGame X870E Vulcan motherboard, using liquid nitrogen.

Iran is offering to sell advanced weapons systems including ballistic missiles, drones and warships to foreign governments for cryptocurrency, in a bid to use digital assets to bypass western financial controls. From a report: Iran's Ministry of Defence Export Center, known as Mindex, says it is prepared to negotiate military contracts that allow payment in digital currencies, as well as through barter arrangements and Iranian rials, according to promotional documents...

Three decades after RFC 1883 promised to future-proof the internet by expanding the available pool of IP addresses from around 4.3 billion to over 340 undecillion, IPv6 has yet to achieve the dominance its creators envisioned. Data from Google, APNIC and Cloudflare analyzed by The Register shows less than half of all internet users rely on IPv6 today. "IPv6 was an extremely conservative protocol that changed as little as possible,"... Read more ›

Some years ago, I was writing a science fiction short story in which I wanted to incorporate verses from a 1928 song, "Button Up Your Overcoat." However, when I sold the story, my editor told me that since the song was still copyrighted, it was safer not to include the verses. If I had written […] Read more ›

UBC Okanagan researchers have uncovered how plants create mitraphylline, a rare natural compound linked to anti-cancer effects. By identifying two key enzymes that shape and twist molecules into their final form, the team solved a puzzle that had stumped scientists for years. The discovery could make it far easier to produce mitraphylline and related compounds sustainably. It also highlights plants as master chemists with untapped medical potential. Read more ›

Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process incoming information before sending signals onward. This reveals a missing layer of brain communication that has been invisible until now. The discovery could reshape how scientists study learning, memory, and brain disease. Read more ›

A new randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking... Read more ›

Scientists discovered that common food emulsifiers consumed by mother mice altered their offspring’s gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. As adults, the offspring were more vulnerable to gut disorders and obesity. The findings suggest that food additives may have hidden, lasting effects beyond those who consume them directly. Read more ›

The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds and speed up melting, while emissions from nearby oil fields alter the chemistry of the air. These interactions trigger feedback loops that let in more sunlight, generate smog, and push warming even further. Together, they paint a troubling picture... Read more ›

MIT researchers have designed a printable aluminum alloy that’s five times stronger than cast aluminum and holds up at extreme temperatures. Machine learning helped them zero in on the ideal recipe in a fraction of the time traditional methods would take. When 3D printed, the alloy forms a tightly packed internal structure that gives it exceptional strength. The material could eventually replace heavier, costlier metals in jet engines, cars, and...

A major breakthrough in battery science reveals why promising single-crystal lithium-ion batteries haven’t lived up to expectations. Researchers found that these batteries crack due to uneven internal reactions, not the grain-boundary damage seen in older designs. Even more surprising, materials thought to be harmful actually helped the batteries last longer. The discovery opens the door to smarter designs that could dramatically extend battery life and safety. Read more ›

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. Two populations facing different kinds of change can end up on completely different evolutionary paths. The findings challenge the idea that one population’s response can represent a whole species.

A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before. Researchers discovered that only the crystal’s outer surfaces become superconducting—allowing electrons to flow with zero resistance—while the interior remains ordinary metal. Even stranger, the electrons on the surface pair up in a highly unusual pattern that breaks all known rules of superconductivity. Read more ›

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone emergency fix that helps them survive. Some cancer cells rely heavily on this backup system, even though it makes their DNA more unstable. Blocking this process could expose a powerful new way to target tumors. Read more ›
