Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light’s intensity and color. Researchers say these materials act more like adjustable systems than simple switches. The finding could lead to a new generation of light-powered sensors and devices.

![[Перевод] Что именно делал компилятор: как ассемблер помогает разобраться в производительности кода на C++](https://times42.com/media/1/1/5/12512115_640x200.jpg "[Перевод] Что именно делал компилятор: как ассемблер помогает разобраться в производительности кода на C++")
Расскажу вам одну историю о том, как смог прокачаться в качестве C++-программиста. Мне в этом помогло не чтение стандарта. Я тогда ещё не понимал до конца метапрограммирование с использованием шаблонов (честно говоря, прямо сейчас эту тему изучаю). Нет, просветление наступило, когда я всмотрелся в целую простыню кода на ассемблере x86–64, но не запаниковал, а подумал: “O, нет, нет. ЧТО ТАМ сделал компилятор?”Читать вывод компилятора — это не какое-то мистическое тёмное... Read more ›

На маркетплейсе покупатель сначала видит картинку и только потом — цену, бренд и отзывы. Главное фото в выдаче решает, кликнут по вам или пролистнут к соседу, поэтому слабый визуал означает слитый трафик и низкий CTR. Долгое время выход был один: платить дизайнеру и ждать правки по два-три дня.

Весной 2022 года я поднимал в этом блоге две необычные темы из области фундаментальной химии. Первая называлась «Из чего состоит мировой эфир. Последняя теория Менделеева» — в ней я рассказывал, как Дмитрий Иванович Менделеев, продолжая опираться на атомный вес, пытался надстроить «нулевой» период над водородом и, вероятно, неосознанно двигался к открытию нейтрона. Вторая статья называлась «Распад протона – невозможность 2,5 класса». Наряду с проблемой практически абсолютной стабильности протона (без внешне Read more ›

Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key building block of the cholesterol-carrying particles linked to clogged arteries and heart disease.

Scientists at McGill University have found a way to supercharge the immune system’s natural killer (NK) cells, helping them break through the defenses tumors use to stay alive. By temporarily blocking two proteins, researchers turned these cells into far more effective cancer fighters against difficult cancers like leukemia, glioblastoma, kidney cancer, and triple-negative breast cancer.

Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults did not.

A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species. About the size of a golf ball, the tiny creature stunned researchers during a deep-sea expedition when it suddenly appeared on camera, crawling across the ocean floor near an underwater mountain.

Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic material — a mistake linked to aging, cancer, and other major diseases. Researchers discovered that not all of these failures are equal. Read more ›

Generative AI is transforming the workplace faster than ever, but new research from the University of Vaasa suggests the biggest threat may not be AI itself — it’s falling behind in learning how to use it. Researcher Zhe Zhu found that employees who see tools like ChatGPT and Gemini as helpful collaborators rather than job-stealing rivals tend to be more engaged, adaptable, and optimistic about their careers.

A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who didn’t receive them. Read more ›

Deep inside 100-million-year-old amber from Myanmar, scientists uncovered a bizarre ancient bug with clawed front legs that look more like a crab’s pincers than anything seen in modern insects. The discovery is so unusual that researchers say these crab-like “chelae” evolved independently in this lineage, making it only the fourth known example of such structures appearing in insects at all.

Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may have helped it gulp air and a light-sensitive organ...

New NIH research reveals that semaglutide sparks different responses inside appetite-controlling brain cells, offering fresh insight into why GLP-1 weight-loss drugs don’t work the same for everyone. Scientists also found a possible way to extend the drugs’ effects, potentially helping patients push past weight-loss plateaus. Read more ›
