New research reveals why early human attempts to leave Africa repeatedly failed—until one group succeeded spectacularly around 50,000 years ago. Scientists discovered that before this successful migration, humans began using a much broader range of environments across Africa, from dense forests to harsh deserts. This ecological flexibility, developed over thousands of years, gave them the adaptive edge needed to survive the more difficult exit routes into Eurasia.

Интеграция больших языковых моделей (LLM) в процессы промышленной автоматизации долгое время упиралась в серьезное ограничение: базовые ИИ-модели предлагают лишь обобщенные фрагменты кода, которые инженеру приходится вручную адаптировать под архитектуру конкретного проекта. Этот процесс сопряжен с риском галлюцинаций, не учитывает реальную топологию сети и часто сводит на нет всю экономию времени. Читать далее Read more ›

# Как мы четыре раза неправильно диагностировали зависание на джобе 281 339Несколько месяцев назад я писал, [как мы четыре раза неправильно чинили мерцание](https://habr.com/ru/articles/1042962/) при рендеринге 4,4 миллиона полигонов. Тогда казалось, что это рекорд: месяц блужданий, четыре отброшенных подхода, решение на неделю. Эта история хуже. Баг пережил четыре диагноза подряд, два из которых мы успели «подтвердить числами», получил по дороге три работающих фикса от несуществующих причин - и в итоге ока Read more ›

1С 7.7 сегодня живет в странном статусе: платформа давно не новая, типовые решения на ней уступили место 1С 8, но в реальном бизнесе старые базы продолжают работать. Часто это сильно доработанные конфигурации, которые годами закрывали конкретные процессы компании, и переписать их «на восьмерку» быстро не получается. С нейросетями похожая история: для 1С 8 примеров, обсуждений и готовых фрагментов заметно больше, а код под 7.7 они пишут менее уверенно. Синтаксис вроде... Read more ›

Всем привет!Ранее мы разбирались с одним конкретным примером - Supabase: как его поставить, зачем он нужен, какие есть аналоги и почему вокруг него в последнее время так много шума.Но, мне кажется, что сейчас будет правильно сделать шаг назад и поговорить не про конкретный сервис, а про весь BaaS (Backend-as-a-Service). Как мы уже узнали из прошлой статьи, Supabase не возник сам по себе, до него был Firebase, а до Firebase были... Read more ›

A trio of major studies found that finerenone may protect the kidneys and heart in far more people than previously thought. The drug significantly slowed kidney disease progression and reduced the risks of kidney failure, heart failure, cardiovascular death, and overall mortality. Researchers saw benefits not only in patients with diabetes but also in those with non-diabetic kidney disease, a group with limited treatment options. Read more ›

A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a lower risk of developing dementia, while higher nitrate and nitrite intake from red meat, processed meat, and even drinking water was linked to a greater risk.

Ancient grooves on human teeth, once hailed as evidence of tooth-picking, may simply be the result of natural wear, according to a new study of wild primates. The research also revealed that a common modern dental defect appears to be uniquely human, hinting that today's lifestyles may be reshaping our teeth in unexpected ways. Read more ›

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together in a timeless "block universe." The argument suggests that physicists may be blurring the difference between things that exist and things that merely occur, creating deep confusion about what space-time actually is. Read more ›

Scientists have uncovered a key brain signal that helps us break old habits and adapt when circumstances suddenly change. By watching mice navigate a virtual maze, researchers found that disappointment—when an expected reward failed to appear—triggered a surge of the neurotransmitter acetylcholine, making the animals more likely to try a new strategy. When acetylcholine was blocked, the mice became less flexible and were more likely to stick with outdated choices. Read more ›
