Reptiles have been growing armor in their skin on and off for hundreds of millions of years, but scientists never fully understood how it evolved. A massive new evolutionary study shows these skin bones appeared independently in multiple lizard groups rather than coming from a single armored ancestor. Even more astonishing, Australian goannas lost this armor long ago — then evolved it back again millions of years later.

Когда бизнес просит объяснить, почему модель вчера одобрила заявку, а сегодня отклонила похожую, одной записи с предсказанием уже недостаточно. В статье разберём, как выстроить воспроизводимый ML‑пайплайн с контролем данных, версий и состояний, чтобы решения модели можно было восстановить, проверить и обосновать. Разобрать пайплайн Read more ›

Когда я учился в университете, мне повезло с преподавателем математического анализа. Он не просто объяснял теоремы и выводил формулы на доске — ему удалось показать красоту чистой математики и то, что за каждой абстрактной конструкцией скрываются вполне реальные инженерные задачи.Иногда вместо обычных лекций он приглашал своих бывших студентов, уже работавших в в самых разных сферах. Например, на предприятии, где изготавливались крупногабаритные металлические конструкции из сверхтолстой стали, для контроля. Read more ›

A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope the discovery will lead to healthier ways to enhance the cardiovascular and performance benefits of dietary nitrate without relying on sugar. Read more ›

Chimpanzees showed a remarkable attraction to crystals, choosing them over ordinary stones and studying them with intense curiosity. The results suggest that the same unusual features may have fascinated early humans long before crystals had any practical use. Read more ›

A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still tadpoles, giving them a head start before the fungus can attack after metamorphosis. The study also uncovered a vast collection of previously unknown antimicrobial peptides that could someday inspire new drugs to fight infections. Read more ›

Going to the cinema, visiting museums, or attending concerts may do more than entertain. Researchers found that older adults who regularly participated in cultural activities tended to have bodies that functioned like those of people about three years younger. They believe stronger social ties, better mental health, and healthier habits could help explain the link, although more research is needed to determine whether cultural activities directly slow aging.

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm. The findings match long-standing predictions and suggest our corner of the galaxy may contain many more undiscovered white dwarf binaries. Read more ›

Humans are often described as the planet's ultimate "super-predator," but wild animals do not fear every human the same way. After analyzing three decades of research, scientists found that animals become much more alert and spend less time feeding when people pose a real threat, such as hunters or fishers. In contrast, tourists, researchers, and other non-lethal humans trigger far weaker and less predictable reactions. Read more ›

A 1,600-year-old mummy discovered in Egypt has revealed something archaeologists had never seen before: a fragment of Homer’s Iliad used during embalming. The papyrus was identified as part of the famous "Catalogue of Ships," one of the best-known sections of the ancient epic. Researchers say it is the first archaeological evidence of a Greek literary text being intentionally incorporated into the mummification process, adding a fascinating new chapter to the...

NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose reflective shells brighten the water enough to be seen from space. An astronaut aboard the International Space Station also photographed the bloom spreading through the Bosphorus, revealing swirling currents. Read more ›
