A simple brain-training program that sharpens how quickly older adults process visual information may have a surprisingly powerful long-term payoff. In a major 20-year study of adults 65 and older, those who completed five to six weeks of adaptive “speed of processing” training — along with a few booster sessions — were significantly less likely to develop dementia, including Alzheimer’s disease, even two decades later. Participants who received the boosted speed training had a 25% lower dementia risk compa

I’ll be honest with you. There was a stretch in my mid-thirties where I had more people around me than at any other point in my life. Corporate colleagues, clients, acquaintances from networking events, the whole lot. And yet I’d never felt more alone. Not because nobody was there. But because the conversations never seemed ...

Расширение стека средств защиты информации на предприятиях, и в особенности внедрение SIEM-систем, неизбежно ведет к кратному увеличению потока событий, поступающих на обработку аналитикам. Как следствие, рост нагрузки на сотрудников вызывает увеличение показателей MTD (среднее время обнаружения) и MTTR (среднее время реагирования).Одним из решений этих проблем выступает класс систем SOAR — Security Orchestration, Automation and Response. SOAR фокусируется на реагировании и управлении инцидентами и становит Read more ›

Кофеин целенаправленно восстанавливает способность распознавать знакомых людей, вспоминать их лица и имена, даже при дефиците сна. Это связано со способностью кофеина питать область CA2 гиппокампа. Социальная память избирательно нарушается, когда мозг лишен полноценного отдыха, что приводит к ослаблению связи между нейронами. Наливайте кофе и готовьтесь вспоминать Read more ›

Современный бизнес переживает очередную трансформацию под влиянием информационных технологий. Он движется от стадии слепого принятия концепций больших данных (Big data) и искусственного интеллекта к более осознанной работе с информацией. На этом фоне появляются новые профессии, такие как инженер по обеспечению качества данных — data quality assurance engineer, или просто инженер DQ, как часто указывают в вакансиях. Почему эта профессия на пике востребованности, где она нужна и кому легче освоить её... Read more ›

После того как я написал статью про то, что ваш монитор не умеет показывать бирюзовый и 65% видимых цветов для него просто не существуют, один мой знакомый (далекий правда от технической отрасли) спросил: «Окей, монитор врёт, а что тогда делает JPEG с оставшимися 35%?» И это хороший вопрос. Я полез в спеку, а через полчаса забыл, зачем вообще полез. Потому меня уже интересовало другое: ребята, которые в 1992-м финализировали этот... Read more ›

Как именно чип понимает, какую инструкцию он должен выполнить? В случае с Intel 8087 этот вопрос оказывается гораздо глубже, чем просто разбор опкодов. За внешне компактным набором команд скрывается многослойная система декодирования: наблюдение за шиной, работа с ESCAPE-опкодами, комбинация логики, PLA и микрокода, а также отдельные аппаратные ветки для специальных случаев.В статье — разбор того, как это реализовано на уровне кристалла: от структуры инструкций и роли ModR/M до выбора микрокодовых...

A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix of rock and metal forged through countless violent collisions? To find out, researchers simulated how a massive crater near Psyche’s north pole formed, revealing that the asteroid’s internal “porosity”... Read more ›

A key Alzheimer’s drug has finally revealed its secret. Researchers discovered that lecanemab works by activating the brain’s immune cells—but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, prompting microglia to clear harmful amyloid plaques. The finding could reshape how future Alzheimer’s therapies are designed. Read more ›

Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of sulfur deep inside. Observations from the James Webb Space Telescope revealed unusual sulfur-rich gases in its atmosphere and a surprisingly low density for its size. Read more ›

Bull sharks may have a reputation as lone hunters, but new research reveals they actually form social bonds and even have preferred “friends.” After six years of observing 184 sharks in Fiji, scientists discovered these animals don’t just mix randomly—they choose companions, swim together, and even follow one another in coordinated ways.

Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones. Read more ›

A new study put ChatGPT to the test by asking it to judge whether hundreds of scientific hypotheses were true or false—and the results were far from reassuring. While the AI got it right about 80% of the time on the surface, its performance dropped significantly when accounting for random guessing, revealing only modest reasoning ability. Even more concerning, it frequently contradicted itself when asked the exact same question multiple... Read more ›

Researchers have pushed quantum chip design into a new era by simulating every physical detail before fabrication. Using a supercomputer with nearly 7,000 GPUs, they modeled how signals travel and interact inside an ultra-tiny chip. Unlike earlier “black box” approaches, this method captures real materials, layouts, and qubit behavior. The result is a powerful new way to spot problems early and build better quantum hardware faster. Read more ›

MIT physicists have built a powerful new microscope that uses terahertz light to uncover hidden quantum motions inside superconductors. By compressing this normally unwieldy light into a tiny region, they were able to observe electrons moving together in a frictionless, wave-like state for the first time. This discovery opens a new window into how superconductors really work. It could also help drive future breakthroughs in high-speed wireless communication. Read more ›

A new tomato-picking robot is learning to think before it acts. Instead of simply identifying ripe fruit, it predicts how easy each tomato will be to harvest and adjusts its approach accordingly. This smarter strategy boosted success rates to 81%, with the robot even switching angles when needed. The breakthrough could pave the way for farms where robots and humans work side by side.

Kepler-51d is a giant, ultra-light “super-puff” planet wrapped in an unusually thick haze that’s blocking scientists from seeing what it’s made of. Observations from JWST revealed that this haze may be one of the largest ever detected, possibly stretching as wide as Earth itself. The planet’s low density and close orbit don’t match existing models of how gas giants form or survive. Now, researchers are left with more questions than... Read more ›
