A groundbreaking Swedish study that tracked people for nearly 50 years has revealed when the body’s physical decline quietly begins. Researchers found that fitness, strength, and muscle endurance start slipping around age 35, with the decline accelerating over time. But there’s an encouraging twist: adults who became active later in life still improved their physical performance by up to 10 percent.

Самой важной частью шахматной программы, которая вносит основной вклад в силу игры, является направленный перебор. А самой главной частью направленного перебора являются отсечения и сокращения наиболее неперспективных ходов. Отбрасывая наименее важные ветви, программа вкладывает ресурсы машины в наиболее перспективные варианты. Чем больше отсекает программа, тем дальше она углубляется по дереву вариантов. И чем глубже она считает, тем сильнее играет.Если бы программа считала до конца - до конечного результа Read more ›

Запутались в многоэтажных SQL‑запросах? Обобщённые табличные выражения (CTE) — тот инструмент, который превращает лапшу из JOIN и подзапросов в читаемый, модульный код. Разберем на реальных примерах из FinTech и e‑commerce, как разбивать сложную логику на цепочку простых шагов, использовать CTE в UPDATE/DELETE, строить рекурсии для иерархий и избегать ловушек оптимизатора в PostgreSQL.

Стек: prisma-generator-express + prisma-guard: генерация CRUD-роутера, валидация ввода, ограничение формы запроса и изоляция тенантов. Подход я для себя называю shape-as-boundary: форма запроса становится исполняемой границей доступа.В примерах ниже - сайт аренды/продажи недвижимости. Реальный проект был другим, кадровой платформой, но я перевожу примеры на недвижимость, чтобы не добавлять лишний контекст. Читать далее Read more ›

Наверное многие из вас помнят шахматные состязания людей против компьютеров, которые проводились еще относительно недавно. Обычная картина для того времени - на сцене, за шахматным столом, под светом софитов и вспышками фотокамер в своих креслах расположились два человека. Один из них - шахматный гроссмейстер, сосредоточенно смотрит на доску. Второй же - оператор, часто поглядывает на экран монитора, который установлен рядом. Многочисленные зрители затаив дыхание наблюдают за этим действом со стороны.Но... Read more ›

Scientists may have uncovered a surprising secret behind why life exists at all. A new study suggests that the Universe’s fundamental constants — the deep physical rules that govern everything from atoms to stars — appear to sit within an incredibly narrow “sweet spot” that allows liquids to flow properly inside living cells. Even tiny shifts in these constants could make blood too thick, water too sticky, or cellular motion... Read more ›

Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able to encourage healthier bacteria while reducing disease-linked microbes tied to gum disease. Even more intriguing, the bacterial conversations changed depending on oxygen... Read more ›

A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease — a condition that affects millions and often leads to dialysis. In a clinical trial involving 150 patients, researchers found that lubiprostone, a medication normally used to treat constipation, helped preserve kidney function in people with moderate CKD. Scientists traced the effect to changes in gut bacteria that boosted production of spermidine, a compound... Read more ›

Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced. Even more surprising, people and mice missing this protein don’t become obese as... Read more ›

Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mice, marking a major step toward future treatments that could replace... Read more ›

Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the site using tiny calcite crystals inside animal bones, revealing the tools are much older than expected. The discovery challenges the idea that human creativity only thrives in easy, prosperous times. Read more ›

Fur seals may look like they’re simply resting after exhausting hunting trips at sea, but their bodies are secretly working overtime. Scientists discovered that hours after returning to land, the seals’ heart rates suddenly surge — sometimes doubling — as they recover from the intense physical stress of deep diving. The findings suggest that seals postpone much of their recovery until they’re safely ashore, likely flushing out lactic acid and... Read more ›

Scientists may have found a smarter, safer way to wipe out termites hiding inside homes. A chemical called bistrifluron prevents drywood termites from forming new exoskeletons during molting, killing entire colonies from within. In tests, it eliminated about 95% of termites while avoiding the toxic side effects of traditional fumigation. Researchers say the method could provide longer-lasting protection as termites spread into new areas. Read more ›

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system. Even more exciting, these strange particles may be adjustable, allowing scientists to tune their behavior in ways never before possible. Read more ›

A new study shows that listening to your own favorite workout music can dramatically boost endurance. Cyclists exercising with self-selected songs lasted nearly 20% longer than when riding in silence, yet they didn’t feel more exhausted at the end. Researchers say music may help people stay in the “pain zone” longer without increasing perceived strain. Read more ›
