Gamma-ray flares from blazars can be accompanied by high-energy neutrino emission. To better understand this phenomenon, an international research team has statistically analyzed 145 bright blazars. They constructed weekly binned light curves and utilized a Bayesian algorithm, finding that their sample was dominated by blazars with low flare duty cycles and energy fractions. The study suggests that high-energy neutrinos of blazars might be produced mainly during the flare phase.

Итан Сигел (американский астрофизик-теоретик и научный журналист, автор рубрики "Спросите Итана", один из пропагандистов современных научных знаний), опубликовал эту статью в далеком 2020-м в ответ на вопрос одного из читателей. @avshkol перевел эту захватывающую статью (и снабдил несколькими примечаниями, в т.ч. с более подробным разъяснением немногочисленных формул, а также упоминанием роли русского ученого Александра Фридмана), поскольку в ней кратко и доступно рассказана история взглядов на динамику наш Read more ›

Motorola is onto something with the Moto Edge 70 Max – the phone combines a large, high-quality display (6.83” LTPO OLED with 1440p+ resolution, 10-bit colors and 144Hz refresh rate) with a chipset powerful enough to drive it (Snapdragon 8 Gen 5), a large battery to last long streaming or gaming sessions (7,100mAh, 90W wired, 25W wireless charging – with magnets!) and a rugged build (IP69, MIL-STD-810H). However, last week’s... Read more ›

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow. Read more ›

Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent's unique mammals evolved. The discovery challenges the idea that Australia's marsupials all came from a single straightforward ancestral lineage. 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 ›
