Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crystal’s underlying symmetry, creating an almost impossible-sounding effect where two rotations combine into one spi

Меня зовут Иван, и я счастливый обладатель ЧПУ станка CNC3018. Точнее даже так: я уже два года счастливый обладатель набора для изготовления печатных плат на ЧПУ: CNC3018, модуль лазерной гравировки, свёрла, фрезы, хотя у меня был набор конкретных проектов плат, которые я хотел сделать. Но я собрал станок, доработал болгаркой лазерный модуль (он квадратный, а крепление — круглое). Попробовал запускать дома — шумно. Перенёс в мастерскую — всё ок, я... Read more ›

В десятой части при изучении случайного леса мы наткнулись на проблему: переход от одиночного дерева к лесу частично снизил дисперсию, но вопрос со смещением остался открытым. Сегодня мы перейдем к концепции градиентного бустинга, которая позволяет последовательно сводить смещение к нулю, и заодно разберем, как заставить деревья эффективно учиться на ошибках своих "предшественников".

Now, Insta360 has filed two countersuits against DJI in the US, asserting DJI infringed its patents related to gimbal and 360° camera tech. Insta360 says the patents infringed by DJI relate to gimbal stabilization, gimbal directional control,... Read more ›

In early April, a staffer for Sam Liccardo, a freshman congressman representing the heart of Silicon Valley, got a call from a reporter telling them he was about to receive an endorsement—from Leading the Future, the $125 million political action committee funded by Andreessen Horowitz, OpenAI President Greg Brockman and Palantir billionaire Joe Lonsdale. It was the first Liccardo and his team had heard about the support. Under normal circumstances,... Read more ›

Я много раз слышал мнение, что Dolby «убивает верх» и делает кассеты мутными. Но Dolby — это не эквалайзер и не простой шумодав. Это система, которая должна работать парой: кодирование при записи и декодирование при воспроизведении. Я решил проверить, что будет, если записать один и тот же материал с Dolby B, с Dolby C, а потом намеренно перепутать режимы на воспроизведении.В сравнении Type I–IV мы уже гоняли один альбом через...

Researchers have finally resolved a key problem in a 100-year-old theory of color, showing that the qualities we perceive in colors are intrinsic to the mathematics of color space itself. The discovery sharpens our understanding of human vision and could lead to more precise color technologies and visualizations. Read more ›

A traditional Chinese medicinal root used for over a thousand years is attracting new scientific attention for its potential to combat hair loss. Studies suggest Polygonum multiflorum can block harmful hormones, activate hair-growth signals, protect follicles, and boost blood flow to the scalp. Researchers say the herb’s effects align remarkably well with both ancient descriptions and modern hair biology. Read more ›

A trio of major studies found that finerenone may protect the kidneys and heart in far more people than previously thought. The drug significantly slowed kidney disease progression and reduced the risks of kidney failure, heart failure, cardiovascular death, and overall mortality. Researchers saw benefits not only in patients with diabetes but also in those with non-diabetic kidney disease, a group with limited treatment options. Read more ›

A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a lower risk of developing dementia, while higher nitrate and nitrite intake from red meat, processed meat, and even drinking water was linked to a greater risk.

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together in a timeless "block universe." The argument suggests that physicists may be blurring the difference between things that exist and things that merely occur, creating deep confusion about what space-time actually is. Read more ›

Scientists have uncovered a key brain signal that helps us break old habits and adapt when circumstances suddenly change. By watching mice navigate a virtual maze, researchers found that disappointment—when an expected reward failed to appear—triggered a surge of the neurotransmitter acetylcholine, making the animals more likely to try a new strategy. When acetylcholine was blocked, the mice became less flexible and were more likely to stick with outdated choices. Read more ›
