Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.

В начале 1980-х годов рынок персональных компьютеров представлял собой шумный базар, изобилующий разнообразием. У каждого отдельного типа персонального компьютера — от Atari, Radio Shack, Apple, Commodore, Texas Instruments и многих других — была своя собственная субкультура, состоящая из клубов и журналов, наполненных сторонниками, готовыми воспевать превосходство выбранных ими машин. [1]Хотя значительная клика мелких производителей, таких как North Star и Vector Graphic, поддерживала стандарт аппаратного. Read more ›

Как технически безупречный запрос на серверную завернули на финкомитете — и что я изменил, чтобы бюджет всё-таки дали. Мой профиль — строить ИТ-подразделения, которые из банальной поддержки превращаются в подразделение, с которым считаются при принятии бизнес-решений. А если точнее — приходить туда, где от ИТ остались руины, и за полгода собирать направление и команду заново, в рамках жёстких ограничений. Вот одна история из практики, которая многому меня научила. Придя в... Read more ›

Каждый раз, когда заходит разговор "что дешевле — поднять у себя открытую модель или платить за API", его почему-то ведут в ценах за токен. И почти всегда это спор не в тех единицах.Во-первых, self-hosting — это постоянные затраты, а API — переменные. Значит, ответ зависит не от цены за токен, а от того, насколько плотно вы это железо загрузите. Во-вторых, токены вообще никто не покупает как цель. Покупают решённые задачи.... Read more ›

Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These protective effects disappeared when the receptor was removed, strengthening the connection. Surprisingly, plant-based compounds such as caffeic acid seemed far more active than caffeine itself.

The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external. Read more ›

Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around stars and how comets, asteroids and meteorites may have carried those ingredients to Earth.

A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems. Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atrial fibrillation. Unlike genetic risk scores, which remain fixed throughout life, the system captures biological changes linked to a person’s... Read more ›

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 ›

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is closely connected to other major planetary threats, including warming, pollution, biodiversity loss, and ocean acidification. Read more ›
