370 Gravitational waves may have created dark matter in the early universe

ScienceDaily
ScienceDaily · 04/25/2026 10:16 EDT

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself. New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today.

Server Actions без ручного API, предсказуемый useActionState для inline CRUD в Next.js

В Next.js формы и inline CRUD довольно быстро упираются в одну и ту же развилку. Можно пойти привычным путём и собрать ручной API: отдельный route handler, fetch из клиента, локальные флаги pending, error, success, плюс своя логика для blur, Enter, Escape и закрытия редактора. На небольшом примере это выглядит терпимо. Но как только в проекте появляются создание, переименование, удаление и несколько inline-форм на одном экране, код начинает расползаться не по... Read more

Базовый минимум метрик, который реально работает у меня (но и у вас тоже будет)

Всем привет! Я, Дианов Стас, product manager. Сегодня разработка фичей и продуктов действительно очень похожа на сложный производственный конвейер, только вместо токарных станков — Jira, пайплайны CI/CD и вечный, леденящий душу вопрос «а когда в прод?» от бизнеса.На таком «заводе», особенно если мы говорим о финтехе с его регуляциями и ценой ошибки, выживают те команды, которые не только пишут чистый код, но и умеют измерять, как этот код проходит путь...

Нейтродин. Забытая радиосхемотехника 1920-х

С нежностью и умилением вспоминая кухонные радиотехнологии предков, самодельные детали приёмников и передатчиков на заре эры радиовещания — резисторы [1], конденсаторы [2], детекторы [3], грешно не сказать несколько слов и о нейтродине — как о примечательном и своеобразном явлении в тогдашнем радио, тем более что термин этот нам уже не раз попадался (нейтродинные конденсаторы). Отдадим дань и находчивости тогдашних конструкторов, пользовавшихся и творящих из небогатого доступного ассортимента, причём решени Read more

A major research study is challenging one of evolution’s most influential ideas: that most genetic changes that become permanent are essentially neutral. Researchers at the University of Michigan found that beneficial mutations are actually far more common than scientists have long assumed. The puzzle is that these advantageous mutations rarely spread through entire populations. Their answer? Nature keeps changing the rules. Read more

A decades-old mystery about Saturn has finally been solved thanks to the James Webb Space Telescope. Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s unprecedented observations revealed that Saturn’s northern lights actively heat the atmosphere, creating winds that generate electrical currents, which then power the aurora all over again in a...

Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building proteins begins to jam and malfunction over time. Tiny structures called ribosomes start colliding and stalling while reading genetic instructions, triggering a chain reaction that leads to faulty proteins and harmful clumps linked to diseases like Alzheimer’s.

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. Read more
