Engineers at a deep underground research facility noticed something strange during major rainstorms: airflow underground sometimes reversed direction. Using new sensors and mathematical modeling, they found that water rushing down a shaft was effectively pushing air through the tunnels like a giant piston. The breakthrough explains a long-standing mystery and could help underground operations better predict and manage ventilation during storms and emergencies.

Champagne and Bullets belongs on the Mount Rushmore of bad movies

There's something about a movie like The Room, Troll 2, or Fateful Findings that I find irresistible.

Конец парольного SMTP: хронология по первоисточникам — и что изменение политики Яндекса и Mail видно в DNS

TL;DR. Этим летом Mail (VK) и Яндекс ограничили бесплатный доступ к почте по IMAP/POP3/SMTP — новости об этом на Хабре уже были, эмоций в комментариях тоже хватило. Эта статья — не третья новость, а попытка собрать всю картину по первоисточникам: точную хронологию того, как парольный доступ к почте закрывали Google (2022–2025) и Microsoft (2025–2027), что именно и для кого ограничили в рунете, чем технически парольная авторизация в почтовых протоколах заслужила...

Из 468 749 доменов top-1M, опубликовавших DMARC, реально применяют политику (p=quarantine/reject) 49.31%.

Scientists are testing two promising ways to destroy PFAS, the stubborn “forever chemicals” that can accumulate in water and resist normal treatment. One method uses collapsing vapor bubbles to generate extreme heat and reactive molecules, while the other uses cold plasma and rising gas bubbles to pull PFAS to the surface and break them apart.

A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible drug target that could help control harmful activity in supporting brain cells. Read more

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop. Their results matched both theoretical predictions and simulations performed with a quantum computer. The method could open new paths for exploring quantum dynamics and materials. Read more

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged. Read more

Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team found that collagen’s carefully organized molecular “handedness” can collapse even while the tissue still appears structurally intact and contains the same amount of collagen. This suggests that skin may begin deteriorating at a much deeper level long before conventional imaging can detect... Read more

A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics.

That decline could leave room for galaxies, stars, planets, and life to form locally amid... Read more
