Astrocytes, once thought to be mere brain “support cells,” are now revealed to be key players in fear memory. Researchers found they actively help form, recall, and weaken fear responses by interacting with neurons in real time. Changing astrocyte activity directly altered how strong fear memories became. This breakthrough could lead to entirely new treatments for anxiety-related disorders.

I’ve spent months in the lab testing the latest AR glasses from Xreal and Viture. By “lab,” I mean cozied up on my couch each night, playing my Steam Deck or Nintendo Switch 2 on a huge, virtual screen that only I can see through these glasses. Using AR glasses as a portable display for […] Read more ›

An anonymous reader quotes a report from Ars Technica: When it comes to large language model-powered tools, there are generally two broad categories of users. On one side are those who treat AI as a powerful but sometimes faulty service that needs careful human oversight and review to detect reasoning or factual flaws in responses. On the other side are those who routinely outsource their critical thinking to what they... Read more ›

After forty years of dawn starts and seventy-hour weeks, I discovered the brutal truth about blue-collar retirement: the silence hits harder than any physical job ever did, and nobody warns you that hanging up your work boots means losing everything that told you who you were. Read more ›

Near the corner of Sixth and Market streets in downtown San Francisco, Frontier Tower has become a 15-story haven for the wildest and weirdest thinkers in technology. Floor 11 is full of longevity and health tech enthusiasts. The crypto folks are a floor above, with a lounge full of expensive furniture. AI is on floor 9. And the big event there this weekend is down on floor 8, where a... Read more ›

Ниже представлены рекомендуемые системные требования от разработчиков. На самом деле характеристики для «минималки» чересчур завышены, и игра неплохо себя показывает даже на не самых топовых сборках. Благодаря обширному списку доступных для настройки параметров, вы сможете без проблем запустить Battlefield 6, не покупая дорогостоящее железо. Игроки уже протестировали «шестерку» на «мамонтах» — GTX 1070 и 1080, и результат оказался куда более оптимистичным, чем вы могли подумать. Проект выдает 60–80 кадров в Read more ›

Знаете, бывают проекты, которые начинаются как «сделать быстренько за выходные», а превращаются в эпопею на несколько лет. Вот у меня именно так и вышло.Всё началось с того, что решил я сделать себе каротажную станцию. Идея возникла не просто так. Когда‑то давно закончив РГГРУ и не работая по специальности но имея определенный багаж знаний и желание... решение было принято. Сразу скажу, что более ленивого человека чем я, встречать мне не доводилось,... Read more ›

Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, it delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments. Read more ›

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and polarization, rather than just on a surface. An AI model then reconstructs the data from light patterns, simplifying the process. This could pave the way for faster, denser, and more efficient data storage systems. Read more ›

Scientists have created a microscopic QR code so tiny it can only be seen with an electron microscope—smaller than most bacteria and now officially a world record. But this isn’t just about size; it’s about durability. By engraving data into ultra-stable ceramic materials, the team has opened the door to storing information that could last for centuries or even millennia without needing power or maintenance.

Nicotine e-cigarettes may be one of the most effective tools yet for quitting smoking, according to a sweeping review of global research. By analyzing findings from 14 major reviews spanning nearly a decade, researchers found consistent, high-quality evidence showing that nicotine vapes outperform traditional methods like patches, gum, and even behavioral support. While some lower-quality studies produced mixed results, the strongest data clearly favored nicotine e-cigarettes. Read more ›

What teens eat might matter more for their mental health than previously thought. A sweeping review of nearly 20 studies found that healthier diets are often linked to fewer depressive symptoms, while poor eating habits may go hand in hand with greater psychological distress. Interestingly, focusing on whole dietary patterns—not just individual nutrients—showed more consistent benefits, suggesting that overall eating habits could play a meaningful role during this critical stage...

A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also genetic risk factors like lipoprotein(a). A new, more advanced risk calculator now uses broader health data to better predict heart attack and stroke risk over decades. Read more ›

After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, unaffected side can actually look younger. This unexpected shift seems to reflect the brain’s effort to rewire itself, strengthening healthy regions to compensate for lost function. Read more ›

Scientists have discovered that the ocean’s “missing” plastic hasn’t vanished—it has broken down into trillions of invisible nanoplastics now spread through water, air, and living organisms. These tiny particles may be everywhere, including inside our bodies, raising serious concerns about their impact. Read more ›

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways. Despite the importance of these findings, their work initially struggled to get published, highlighting a deeper issue in science. Read more ›

Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was made possible by ultra-fast X-ray lasers that captured water before it froze. This discovery could reshape our understanding of water’s role in nature—and possibly even life itself. Read more ›
