Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the direction of rotation can unexpectedly flip as momentum is transferred. The strange reversal happens because of the crystal’s underlying symmetry, creating an almost impossible-sounding effect where two rotations combine into one spi

Our social media feeds are being inundated by clips. Big names like Justin Bieber, reality shows like RuPaul’s Drag Race, and even AI companies like Perplexity — they’re all using bite-sized video segments to advertise themselves on social media. And they’re not just posting from their own accounts; they’re paying thousands of anonymous people to […] Read more ›

Waymo is the undisputed leader in the robotaxi space, operating a fleet of over 3,000 driverless cars in at least 10 cities across the US. A number of companies, including Tesla, Zoox, Avride, and Motional, are racing to catch up with the Alphabet-owned firm. But what if being No. 2 was actually better? Nuro, the […] Read more ›

These Russian satellites are getting uncomfortably close to a U.S.- and European-operated radar satellite, particularly in Ukraine, used for reconnaissance missions. While their intentions are unclear, these maneuvers consume a lot of fuel and are not typically undertaken by other satellites. Read more ›

В современной науке о данных и машинном обучении мы постоянно решаем задачу оптимизации: найти в многомерном пространстве параметров точку, минимизирующую функцию потерь. Градиентный спуск, метод Ньютона, эволюционные алгоритмы — все они суть разные способы ответить на вопрос: «Как из точки А (хаос, необученная сеть) попасть в точку Б (порядок, решающая правило)?»Однако за этой, казалось бы, сугубо прикладной проблемой скрывается фундаментальный философский вопрос: обязательно ли наличие единственного «прав Read more ›

Аннотация. В статье рассматривается физическая основа измерений Ekahau Sidekick и механизм применяемого RSSI‑offset с позиций теории антенн, теории шума радиоприёмных устройств, статистической теории сигналов и стандартов IEEE 802.11. Показано, что scalar RSSI‑offset является линейным сдвигом уровня и не моделирует ни реальный SNR клиентского устройства, ни структуру QAM‑созвездия, ни алгоритм rate adaptation, ни роуминговое поведение. Помимо пяти независимых физических и системных причин неточности, рассма Read more ›

Scientists have discovered that the human body undergoes a dramatic internal transformation during extended fasting, with major changes appearing only after about three days without food. In a seven-day water-only fasting study, researchers tracked thousands of proteins in the blood and found widespread shifts affecting organs throughout the body — including the brain. While the body quickly switches from burning glucose to fat, the most intriguing biological changes linked to... Read more ›

Studies suggest watermelon could be a hidden powerhouse for better health. Researchers found that people who eat watermelon tend to have higher-quality diets packed with more vitamins, fiber, and antioxidants — while consuming less added sugar and saturated fat. Another study showed watermelon juice may help protect blood vessel function and support heart health. Read more ›

Scientists have uncovered evidence that the vanished Tethys Ocean may have sculpted Central Asia’s mountainous landscape during the dinosaur era. Using decades of geological data, researchers found that distant tectonic activity linked to the ancient ocean appears to match periods of rapid mountain formation. Surprisingly, climate and mantle processes played only a minor role. The discovery could reshape how scientists understand mountain building across the planet. Read more ›

Coffee may give your blood pressure a temporary jolt, but that doesn’t mean it’s secretly wrecking your heart. Researchers say caffeine can briefly raise blood pressure by stimulating your heart and tightening blood vessels, especially in people who don’t drink coffee regularly. But large studies involving hundreds of thousands of people found no strong evidence that moderate coffee drinking increases the risk of developing hypertension. In fact, coffee also contains...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself. Stephan Schlamminger and his team at NIST painstakingly recreated a landmark French experiment designed to measure “big G,” the universal gravitational constant that governs everything from falling apples to galaxies. When he finally opened a sealed... Read more ›

Scientists have achieved something that once sounded almost impossible: using ordinary sunlight to create quantum-linked photon pairs, a phenomenon normally dependent on precise laboratory lasers. By building a sun-tracking system that funnels sunlight through optical fiber into a special crystal, researchers generated strongly correlated photons capable of performing “ghost imaging,” where images are reconstructed indirectly through quantum correlations. Remarkably, the sunlight-powered setup produced imag Read more ›

Electric vehicles are pushing scientists to tackle one of the biggest hidden energy drains inside electric motors: magnetic energy loss. Now, researchers in Japan have developed a powerful AI-driven physics model that can peer into the chaotic “maze-like” magnetic patterns inside motor materials and reveal how heat and microscopic magnetic structures trigger wasted energy.

Scientists at the University of Cambridge have achieved what was once considered impossible by electrically powering insulating nanoparticles to create a completely new kind of LED. Using tiny organic “molecular antennas,” the team found a way to funnel energy into materials that normally cannot conduct electricity, producing ultra pure near infrared light with remarkable efficiency.

A new study suggests humans became overwhelmingly right-handed because of two major evolutionary shifts: walking on two legs and developing much larger brains. Researchers found that as human ancestors evolved, their right-hand preference steadily intensified — transforming a mild tendency into one of humanity’s most distinctive traits. Read more ›
