450 Scientists found a protein that drives brain aging — and how to stop it

ScienceDaily
ScienceDaily · 04/05/2026 07:08 EDT

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced FTL1, something remarkable happened — the brain began to recover, rebuilding lost connections and restoring memory performance.

Пузырь или не пузырь? Что там с AI-провайдерами?

TLDR; сам инференс прибылен для компаний, они не продают токены дешевле их себестоимости. Проблем в плане пузыря ровным счетом две - избыточные обязательства, взятые на себя в ближайшие годы и неготовность пользователей менять модель поведения, вследствие перехода с request based на usage based подписки.За подробностями прошу под кат.

Как устроены LLM-агенты: архитектура, планирование и инструменты

Если вы хоть раз просили ChatGPT выполнить какую-то задачу и получали в ответ инструкцию "как это сделать" вместо того чтобы он взял и сделал сам - вы столкнулись с ограничением обычной языковой модели. Она умеет объяснять и советовать, но сама ничего не делает: не лезет в интернет, не запускает код, не сохраняет файлы. Просто отвечает. LLM-агент - это другая история. Это система, которая получает задачу и начинает её решать: ищет... Read more

Scientists have uncovered a surprising new way to control superconductivity — the mysterious phenomenon where electricity flows with zero energy loss. By pairing twisted layers of graphene with a synthetic diamond material, researchers were able to effectively switch superconductivity on and off by tweaking how electrons interact with their surroundings. Even more intriguing, the material behaved in ways that defied the rules of conventional superconductors, hinting at an entirely new... 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
