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.

Первая AI-фича часто ломается задолго до релиза — ещё на этапе, когда команда пытается описать, что именно она собирается делать. Привычного PRD с user stories и acceptance criteria уже недостаточно: поведение LLM зависит от промпта, модели, данных для оценки и множества граничных случаев. В статье разбираем, какие разделы стоит добавить в спецификацию AI-продукта, чтобы команда понимала, как измерять качество, контролировать риски и принимать решения после запуска.

The Galaxy S26 series has been a smash hit for Samsung – the trio sold 3 million units in its home country of South Korea in just 118 days. That’s under four months. For comparison, the previous Galaxy S25 generation launched in early February and hit the 3 million mark in early August, which is six months. Before that, the S24 series needed two months more to reach the same... Read more ›

A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. It works on deep and irregular injuries where conventional hemostatic products often struggle and remains effective even after years of storage in harsh conditions. Originally created for the battlefield, the technology could also transform emergency care in disasters, ambulances, and hospitals. Read more ›

A protein called “Mitch” may hold the key to a new generation of obesity treatments. Researchers found that disabling it in human cells boosts fat burning, increases energy use, and makes it harder for new fat cells to develop. The findings help explain why mice lacking Mitch were leaner, more athletic, and resistant to obesity. Read more ›

An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may finally be within reach of discovery. If confirmed, they could solve one of astronomy's greatest mysteries by explaining the nature of dark matter. Read more ›

Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged and damaged blood vessels deep within the brain. The finding helps explain why standard treatments like aspirin are often less effective and is driving the search for new therapies that target the brain’s tiny blood vessels directly. Read more ›

Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow of time and even harvest energy from the measurement process itself. The breakthrough could lead to more powerful quantum computers, quantum batteries, and other advanced technologies. Read more ›

A UCLA study has identified a hidden Achilles' heel in aggressive small cell cancers that have resisted new treatments for decades. Scientists found that tumors lacking the RB gene become critically dependent on the protein E2F3 for survival. Blocking E2F3 shut down tumor growth in laboratory models, and existing FDA-approved drugs may be able to exploit this vulnerability. The discovery could pave the way for faster development of more effective... Read more ›
