Researchers have developed a teeth-whitening powder that works with the vibrations of an electric toothbrush to safely remove stains. Unlike traditional whiteners, it not only brightens teeth but also repairs enamel and supports healthy oral bacteria. Lab tests showed dramatic whitening effects, while animal studies revealed reduced harmful microbes and inflammation. This could pave the way for a new generation of at-home dental care.

На локалке всё летает, а на проде ложится замертво? Дело в масштабировании. Big O — это не скучная теория для алгоритмических собеседований, а реальный инструмент, чтобы ваш код не «убивал» сервера. В этой статье я на простых примерах и без зубодробительной математики объясню, как оценивать сложность своих алгоритмов. От до — только суть, примеры на Python и немного здоровой иронии над медленным кодом. Читать далее Read more ›

Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa. By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even... Read more ›

Dinosaur DNA may still be out of reach, but scientists are uncovering something almost as exciting—ancient blood vessels hidden inside fossilized bones. In a massive Tyrannosaurus rex nicknamed Scotty, researchers discovered a network of preserved vessels within a rib that once fractured and began healing 66 million years ago. Using powerful synchrotron X-rays from particle accelerators, they were able to peer inside the dense fossil without damaging it, revealing intricate,... Read more ›

The famous mezcal “worm” has long puzzled scientists, but DNA testing has finally cracked the case. Researchers found that all sampled larvae were actually agave redworm moth caterpillars—not a mix of species as once believed. While the discovery clears up a long-standing mystery, it also raises concerns about sustainability. Growing demand for mezcal and edible larvae could put pressure on wild populations and the agave plants they depend on. Read more ›

For decades, the Gulf of Panama has relied on strong seasonal winds to trigger upwelling, bringing cool, nutrient-packed water to the surface. But in 2025, this dependable event didn’t happen. Researchers point to unusually weak winds as the likely culprit, reducing ocean productivity and warming coastal waters. The surprise disruption highlights how vulnerable these critical systems may be to climate change. Read more ›

Mixing up your workouts might be the real secret to a longer life. Long-term research tracking over 100,000 people for more than three decades suggests that doing a variety of physical activities—rather than just more of the same—can significantly lower the risk of death. Interestingly, the benefits don’t keep rising endlessly; they seem to level off after a certain point, hinting at a “sweet spot” of activity. Read more ›

A bizarre, cyclops-like creature from nearly 600 million years ago may hold the key to how your eyes—and even your sleep cycle—evolved. Scientists have discovered that all vertebrates, including humans, trace their vision back to a single light-sensitive “median eye” perched atop a worm-like ancestor’s head. As this ancient animal shifted from a sedentary to a more active lifestyle, it lost and then reinvented its vision, eventually giving rise to... Read more ›

A major new study finds that living in pesticide-heavy environments could raise cancer risk by up to 150%, even when the chemicals are considered “safe” on their own. The research suggests these mixtures may silently damage cells years before cancer appears. Read more ›

Deep within the brain, scientists have uncovered a hidden “switch” that may decide whether pain fades away—or lingers for months or even years. Researchers found that a small, little-known region called the caudal granular insular cortex (CGIC) acts like a command center, telling the body to keep pain signals alive long after an injury has healed. In animal studies, shutting down this pathway not only prevented chronic pain from forming... Read more ›

In a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors. Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before. This suggests a major gap in the classic theory of superconductivity.

A group of undergraduate students pulled off something remarkable: they built their own dark matter detector and used it to probe one of physics’ biggest mysteries. Working with limited resources but plenty of creativity, they designed a stripped-down experiment to hunt for axions — hypothetical particles that could make up dark matter. Read more ›
