Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored communication between neurons in this pathway and reversed the memory deficits caused by lost sleep. The effect was remarkably targeted, helping the impaired circuit recover without overstimulating normal brain function.

Всем привет, недавно я собрал и сейчас активно использую ПК для локального запуска хоть сколько-то серьезных LLM, и захотелось поделиться этим опытом с сообществом. На статью меня сподвигло то, что в рунете до обидного мало информации на тему, как собрать ПК на несколько GPU не на майнерском, не на серверном или не на HEDT, а именно на пользовательском железе. Поговорим, про сложности, про возможности домашнего инференса и про опыт использования... Read more ›

Принято считать, что современный IT-мир построили Гейтс, Джобс или Торвальдс. Но без одного бородатого хакера из MIT, который в 80-х вусмерть разругался с принтером Xerox, у нас бы не было ни Linux, ни Android, ни концепции Open Source в её нынешнем виде.Ричард Столлман — создатель проекта GNU и вирусной лицензии GPL, самый радикальный, неудобный и бескомпромиссный философ от мира IT. Долгие годы индустрия считала его эксцентричным параноиком, который принципиально не... Read more ›

Вы всё ещё решаете за своих сотрудников, что им делать? Каждый сложный вопрос идёт к вам?Без вас ничего не работает — ни отпуска, ни больничного?При этом вы слышали, что нужно «систематизировать бизнес», но в голове сразу возникают страшные картинки: горы регламентов, надзиратели с чек-листами, бесконечные планерки и люди, которые делают вид, что работают, а на самом деле заполняют отчёты.Я понимаю. Поэтому сразу скажу главное.Систематизация — это не бюрократия.Это комплекс из... Read more ›

Российские селлеры уже давно действуют так: сначала выбирают нишу, придумывают и регистрируют бренд, затем — закупаются на оптовом рынке КНР (напрямую, через сервис закупки или китайский маркетплейс), далее — перепродают товары здесь. Эта схема иногда становится крайне рисковой: дело в том, что китайские бизнесмены, получив заказ, нередко копируют чужой товарный знак, регистрируют его на себя в своем государстве, а потом «блокируют» предпринимателей-инициаторов цепочки.

Если вы хоть раз ловили себя на мысли «ещё лет пять-семь — и можно будет всё бросить», у этой мысли есть имя, инфраструктура и сорокалетняя история. Называется FIRE — Financial Independence, Retire Early. Финансовая независимость и ранний выход на пенсию. В американском опросе Shopify & Angus Reid в конце 2020 года 9% не вышедших на пенсию взрослых сообщили, что активно идут к FIRE; ещё 39% сказали, что рассматривают такую траекторию.... Read more ›

A colossal new sea predator named Tylosaurus rex has been identified from fossils found in Texas, revealing a brutal 43-foot-long hunter that ruled ancient oceans 80 million years ago. The discovery not only introduces one of the biggest mosasaurs ever known, but also shakes up long-standing ideas about how these marine reptiles evolved. Read more ›

NASA scientists were stunned when a strange radio signal from the Sun refused to fade away. Instead of lasting a few hours or days like normal solar radio bursts, this one persisted for an astonishing 19 days — shattering the previous record. Using a fleet of spacecraft spread across the solar system, researchers tracked the mysterious signal to a massive magnetic structure on the Sun called a helmet streamer. Read more ›

NASA’s Psyche spacecraft skimmed past Mars in a precision flyby that helped catapult it deeper into space toward its ultimate target: the bizarre metal-rich asteroid Psyche. During the encounter, it snapped detailed images of heavily cratered Martian terrain, including the striking double-ring Huygens crater. The flyby gave the spacecraft a critical gravity boost without using extra fuel. Read more ›

Scientists have created an AI-powered system that can scan and map an entire mouse body in extraordinary detail — and it just uncovered a surprising new effect of obesity. Beyond disrupting metabolism, obesity appears to damage facial sensory nerves linked to touch and sensation, while also triggering widespread inflammation across the body. Read more ›

A new analysis is raising concerns about Wegovy, the blockbuster weight-loss drug, after researchers found it may carry the highest risk of a rare “eye stroke” that can cause sudden vision loss. The study, based on millions of FDA side-effect reports, found the risk signal was nearly five times stronger for Wegovy than for Ozempic, despite both containing semaglutide. Read more ›

A breakthrough lithium-extraction method could help solve one of clean energy’s dirtiest problems. Researchers at Columbia Engineering have developed a fast new technique that pulls lithium directly from salty underground brines using a temperature-sensitive solvent, avoiding the giant evaporation ponds that can take years and drain precious water supplies. Even better, the method works on low-quality lithium sources that current technologies struggle to use. Read more ›

Scientists found that storing mangoes at 54°F dramatically slows ripening and keeps the fruit fresh far longer than typical tropical temperatures. The cooler conditions helped mangoes stay firm, retain moisture, and preserve important antioxidants while reducing cellular damage. Researchers also uncovered the internal defense systems that switch on during cold storage, protecting the fruit from stress and decay. Read more ›

A surprising study suggests vitamin D2 supplements may reduce the body’s levels of vitamin D3 — the more effective form of vitamin D. Researchers found D3 not only boosts vitamin D status more efficiently, but may also play a unique role in helping the immune system fight off viruses and bacteria. The discovery is prompting scientists to rethink whether D3 should become the preferred choice for supplementation. Read more ›

A newly identified brain protein may play a major role in how the body ages. Researchers discovered that declining levels of Menin in the hypothalamus triggered inflammation, memory problems, bone loss, and other aging-related changes in mice. Restoring Menin reversed several of these effects, while a simple amino acid supplement called D-serine boosted cognition. The discovery opens a surprising new path for fighting age-related decline.

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crystal’s underlying symmetry, creating an almost impossible-sounding effect where two rotations... Read more ›
