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.

Steam активно портирует игры на Linux с помощью Proton, да и нативные версии игр (особенно учитывая популярность Steam Deck) сейчас не редкость. Но что делать с остальным софтом и играми? Для них есть проверенное решение — Wine и его удобная обертка Bottles.Я решил проверить на практике, насколько сложно запустить олдскульную игру на моей Fedora 43. В качестве подопытного выбрал S.T.A.L.K.E.R.: Тень Чернобыля. Читать далее Read more ›

When the Robotics and AI (RAI) Institute talks technology, it’s wise to take notice. The company was, after all, founded by Marc Raibert, who also launched robotics pioneer Boston Dynamics, the firm behind the astonishing Atlas robot and the dog-like Spot quadruped. Massachusetts-based RAI Institute has just unveiled Roadrunner, a 15 kg (33 lb) bipedal-wheeled robot prototype. […] Read more ›

Postmenopausal women may have a powerful new edge in the battle against weight gain. A Mayo Clinic study found that those using menopausal hormone therapy while taking the obesity drug tirzepatide lost about 35% more weight than those on the drug alone. The findings hint at a surprising synergy between hormones and cutting-edge weight-loss medications, potentially opening the door to more effective, personalized treatments for millions of women facing increased...

The loneliest part of being an overthinker isn’t the racing thoughts — it’s realizing that most people genuinely don’t think about things as deeply as you do and there’s no way to explain that without sounding arrogant. I need to be careful how I say this. Because the moment you try to articulate what it ... Read more Read more ›

Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s measured. This faint rotation in the cosmic microwave background could point to entirely new physics, including hidden particles such as axions and clues about dark matter or dark energy. Read more ›

Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than 10 billion years ago whose light was bent and magnified by a foreground galaxy, creating multiple images through gravitational lensing. Because the light from each image traveled slightly different paths, it arrived at Earth at different times, letting scientists effectively watch different moments... Read more ›

mRNA vaccines saved millions of lives during COVID-19 but have limitations like waning immunity and complex production. Scientists are now testing a new platform called DoriVac, which uses folded DNA nanostructures to better control how the immune system responds. In early studies, it produced strong antibody and T cell responses in both mice and human models. Researchers say it could lead to more stable, easier-to-manufacture vaccines for diseases like COVID-19,... Read more ›

The James Webb Space Telescope has revealed new details in a bizarre nebula that looks like a brain floating in space. Formed by a dying star, the “Exposed Cranium” nebula shows layered gas and a dark central divide that creates its eerie shape. Webb’s infrared view suggests powerful jets may be shaping the structure. The images capture a brief and dramatic phase in a star’s final evolution. Read more ›

Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of “sleep-like” activity during demanding tasks. These moments are linked to more mistakes, slower reaction times, and lapses in attention.

A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix of rock and metal forged through countless violent collisions? To find out, researchers simulated how a massive crater near Psyche’s north pole formed, revealing that the asteroid’s internal “porosity”... Read more ›

A key Alzheimer’s drug has finally revealed its secret. Researchers discovered that lecanemab works by activating the brain’s immune cells—but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, prompting microglia to clear harmful amyloid plaques. The finding could reshape how future Alzheimer’s therapies are designed. Read more ›

Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of sulfur deep inside. Observations from the James Webb Space Telescope revealed unusual sulfur-rich gases in its atmosphere and a surprisingly low density for its size. Read more ›

Bull sharks may have a reputation as lone hunters, but new research reveals they actually form social bonds and even have preferred “friends.” After six years of observing 184 sharks in Fiji, scientists discovered these animals don’t just mix randomly—they choose companions, swim together, and even follow one another in coordinated ways.

Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones. Read more ›
