Wobbling stars reveal hidden companions in Gaia data

Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to sense the gravitational tug or 'wobble' the planet induces on a star. Both the planet and brown dwarf are orbiting low-mass stars, a scenario thought to be extremely rare.

Как мы сделали простой мониторинг загрузки станков через Zigbee-сеть: open source стек без кабелей и вендорлок

На машиностроительном заводе с цехом в несколько десятков единиц оборудования загрузка станков всю жизнь считалась «на глаз» — сменный мастер периодически обходил цех и делал отметки в бумажном журнале. Но сколько именно часов конкретный токарный станок фактически резал металл, а сколько просто стоял включенным вхолостую — без цифрового инструмента понять это было невозможно. В этой статье я разберу конкретное решение на базе беспроводной Zigbee-сети. Простой и дешевый мониторинг вместо кабелей... Read more

ER, ERR и обратная зависимость охвата от вовлечённости

Если загуглить «как посчитать вовлечённость», все источники говорят одно и то же. Реакции поделить на охват, умножить на сто. Это и есть ERR. Формулу повторяют десятки статей и любая нейросеть. Чего не делает почти никто, так это не объясняет, как потом эту цифру читать. А там начинается самое интересное, потому что у метрики есть пара неочевидных свойств, из‑за которых выводы на ровном месте получаются неверными. Читать далее Read more

Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible. Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations. The unusual behavior could open the door to recyclable buildings, reconfigurable structures, and even futuristic robotic technologies. Read more

NASA satellites have detected a vast pulse of warm water reaching the coast of South America, signaling that El Niño is likely developing. The warm water is being carried eastward by massive ocean waves known as Kelvin waves, which also cause sea levels to rise. El Niño can reshape weather patterns worldwide, bringing floods, droughts, and temperature extremes. Read more

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to spot. The effect could be especially important around M-dwarf stars, the most common stars in... Read more

Researchers analyzing health records from nearly 60,000 adults found that people taking semaglutide experienced about 15% fewer fractures than those using other common weight-loss medications, despite losing more weight.
