Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.

Привет, Хабр! На связи команда Рег.облака, а это третья статья про Free Tier. В первой мы считали, что помещается в один‑два гигабайта памяти, во второй перевозили сайт с виртуального хостинга на бесплатный сервер с ispmanager.В обеих статьях был раздел, где мы перечисляли, чего на Free Tier делать не стоит: тяжелые CMS, неоптимизированные проекты под трафиком, серьезные базы. Этот раздел пора переписывать. Стартовал третий этап программы: юрлица получают на два месяца... Read more ›

В декабре 2016 я запустил доску объявлений. В марте 2017 написал на Спарке статью о том, как пытаюсь притащить на неё трафик. Статья была честная до неприличия: три месяца работы, около 14 тысяч рублей на рекламу, 450 рублей выручки.Отдельным памятником стоит таргет во ВКонтакте. 515 тысяч показов, 41 переход, два поданных объявления. CTR ноль целых ноль ноль восемь. Восемь тысячных процента. Я тогда пересчитал трижды, потому что решил, что где‑то... Read more ›

The tech industry is still reeling from the recent Hugging Face incident, where an autonomous, rogue OpenAI model escaped its testing environment and hacked into Hugging Face's systems. Hugging Face tried unsuccessfully to defend itself by using leading US closed models like Anthropic's Fable 5 and was finally able to contain the breach using the open-weight GLM 5.2 by Chinese Z.ai. For context, closed models operate in their own closed... Read more ›

Менеджер проектов в IT — одна из профессий, про которые сложно дать короткое определение. Он не пишет код и не дизайнит. Но от него зависит, выйдет ли продукт в срок, уложится ли команда в бюджет и не сойдёт ли разработка с рельсов в середине пути.По данным Хабр Карьеры, медианная зарплата менеджера проектов — почти 180 тысяч рублей, опытный PM в крупной компании зарабатывает 300–450 тысяч. При этом профессия считается одной... Read more ›

Привет, Хабр! Меня зовут Михаил Рязанский, я руководитель группы технической аналитики в Дзене. Группа включает в себя команды DWH, антифрода, аналитики модерации и ML‑аналитики. Вместе с Марком Хабаровым, лидом команды ML‑аналитики, мы расскажем про наш инструмент для анализа результатов А/Б‑тестов и про интеграцию в него LLM. Получилось интересно, местами — больно. Но обо всём по порядку. Перейдем к подробностям Read more ›

China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnetic shield.

Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the Eyes of K’gari. Read more ›

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage in the brain’s white matter. Surprisingly, sitting itself did not appear to be the main issue, since people who spent long hours seated at mentally engaging jobs... Read more ›

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is generally safe and may even be linked to lower risks of heart disease, stroke, heart failure, and Type 2 diabetes. But the source matters: highly concentrated energy... Read more ›

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical. A single chip could eventually perform several tasks that currently require separate devices, potentially reducing energy use, cost, and complexity in AI servers and data centers. Read more ›

A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more personal insight and later improvements in well-being. The findings suggest that the psychedelic experience itself may help people break free from entrenched patterns of thinking. Read more ›

Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resistance. The combination restored the antibiotic’s ability to kill drug-resistant E. faecium, raising hopes that similar chemical helpers could rescue other failing medicines. Read more ›

MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts. Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals. In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view. Read more ›

Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started. This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalytic reactions. Read more ›
