Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even better when paired with fluoride and xylitol, significantly reducing damage to teeth. The innovation could be especially life-changing for cancer patients who lose saliva production after treatment.

Дисклеймер: это не попытка "доказать Гегеля физикой" или наоборот. Это размышление о том, как философские категории помогают осмыслить то, что физика описывает математически и почему эти два языка говорят об одном и том же, просто разными словами.У меня есть давняя идея - написать книгу о том, как философия Гегеля перекликается с современной физикой. Не в духе "Гегель всё предсказал", а в более тонком смысле: многие структурные ходы его мысли -... Read more ›

"Canonical is no longer pretending that 4GB is enough," writes the blog How-to-Geek, noting Ubuntu 26.04 LTS "raises the baseline memory to 6GB, alongside a 2GHz dual-core processor, and 25GB of storage..." Ubuntu 14.04 LTS (Trusty Tahr) set the floor at 1GB — a modest ask when it launched more than a decade ago in 2014. Then came the Ubuntu 18.04 LTS (Bionic Beaver) that pushed the number to 4GB,...

Когда наши горячо любимые вожди в очередной раз заводят разговоры о том, что для экономического прорыва людям нужно просто работать дольше и без лишних вопросов, всегда за кадром остаётся одна фундаментальная проблема. Технологическая конкуренция XXI века все меньше зависит от того, сколько часов человек способен простоять у станка, и все больше - от того, кто быстрее внедряет автоматизацию, переобучает кадры и встраивается в глобальные производственные цепочки.Человека можно заставить работать дольше....

A 42-core SKU from the upcoming Nova Lake-S CPU family has reportedly been upgraded to 44 cores by swapping the 6P+12E tile with an 8P+12E tile, allowing the chip to achieve symmetry across its dual-tile config. Those leftover 6P+12E tiles could now become locked variants with 144 MB of bLLC as a new 22-core SKU (6P+12E+4LPE). Read more ›

Всё началось на второй паре по системному программированию. Нам дали задачу: написать CLI-утилиту для анализа логов - парсить файл, фильтровать записи по уровню ошибок, считать статистику, выводить красиво в консоль. "Ну понятно", - открыл я vim и началось мое долгое приключение...Неделя. Две. Утилита называлась logz, она умела читать логи nginx и apache, фильтровать по уровню (DEBUG, INFO, WARN, ERROR), по дате, по IP, выводила топ адресов с наибольшим числом ошибок,... Read more ›

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced FTL1, something remarkable happened — the brain began to recover, rebuilding lost connections and restoring memory performance. Read more ›

Apple's HomePod mini today reached a notable milestone, marking 2,000 days since its introduction in October 2020, an unusually long lifespan for an Apple hardware product that has yet to receive a second-generation refresh. Apple unveiled the HomePod mini at its iPhone 12 event on October 13, 2020, positioning it as a smaller and more affordable alternative to the original HomePod. The device launched at just $99, with pre-orders beginning... Read more ›

Не так давно мы с удовольствием рассуждали, какую портативную консоль из Китая купить, чтобы с большим удовольствием окунуться в ретро-гейминг, и даже больше, показывали варианты и цены. А потом кризис добрался и до них.Сейчас почти все флагманские компании так или иначе сокращают производство, убирают устройства с продажи, поднимают цены и в целом делают всё, чтобы усложнить жизнь простому геймеру.В таком случае что мы делаем? Правильно, смотрим в сторону настоящих игровых... Read more ›

Scientists have discovered that the ocean’s “missing” plastic hasn’t vanished—it has broken down into trillions of invisible nanoplastics now spread through water, air, and living organisms. These tiny particles may be everywhere, including inside our bodies, raising serious concerns about their impact. Read more ›

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways. Despite the importance of these findings, their work initially struggled to get published, highlighting a deeper issue in science. Read more ›

Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was made possible by ultra-fast X-ray lasers that captured water before it froze. This discovery could reshape our understanding of water’s role in nature—and possibly even life itself. Read more ›

Far beneath the ocean near Japan, scientists have discovered that the magma system linked to the most powerful eruption of the Holocene is slowly rebuilding. By using seismic imaging, researchers mapped a large magma reservoir under the Kikai caldera and confirmed it is the same system that fueled the massive eruption 7,300 years ago. However, the magma now present is newly injected, not leftover, as shown by changes in the... Read more ›

Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize an egg. In lab experiments simulating space conditions, far fewer sperm successfully made it through a maze designed to mimic the reproductive tract, and fertilization rates... Read more ›

Scientists may have been unknowingly inflating microplastics pollution estimates, and the surprising source could be their own lab gloves. A University of Michigan study found that common nitrile and latex gloves release tiny particles called stearates, which closely resemble microplastics and can contaminate samples during testing. In some cases, this led to wildly exaggerated results, forcing researchers to track down the unexpected culprit. Read more ›

Just a few minutes of getting out of breath each day could dramatically cut your risk of major diseases—including heart disease, dementia, and diabetes. A large study of nearly 100,000 people found that it’s not just how much you move, but how intensely you move that matters. Short bursts of vigorous activity—like rushing for a bus or climbing stairs quickly—were linked to striking reductions in disease risk, especially for inflammatory... Read more ›

A powerful cholesterol-lowering drug may be changing the rules of heart disease prevention. Researchers found that evolocumab, typically used for people who already have cardiovascular disease, can significantly cut the risk of first-time heart attacks and strokes in high-risk patients with diabetes—even before any artery-clogging plaque is detected.

A large U.S. study reveals that more than a quarter of people with hard-to-treat high blood pressure may have an overlooked hormone problem. Elevated cortisol—often linked to stress—was found in 27% of these patients, far higher than expected. This hidden condition could explain why standard medications fail. The discovery could lead to new testing and treatments that finally help bring blood pressure under control. Read more ›

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation. Read more ›
