Cool science: Researchers craft tiny biological tools using frozen ethanol

Imagine drawing on something as delicate as a living cell -- without damaging it. Researchers have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes. By advancing a method called ice lithography, the team was able to etch incredibly small, detailed patterns directly onto fragile biological surfaces.

GitHub и PyPI сбоят в России: РКН предлагает ГосVPN — что это значит и что делать

Если у вас в начале июня внезапно завис git clone, а pip install начал валиться на каждом втором пакете — выдохните, дело не в вас и не в карме. С мая 2026 доступ к ключевым инструментам разработчика из России потихоньку деградирует. 8 июня Роскомнадзор предложил отрасли решение, и отрасль встретила его, мягко говоря, без оваций. Давайте по порядку: что сломалось, почему достаётся именно репозиториям, что это за «ГосVPN» такой, почему... Read more

Заморозка по fingerprint: как ТСПУ в июне 2026 ломает соединения по поведению, а не по протоколу

Полгода назад я написал здесь разбор «почему VLESS работает» — он собрал 169 тысяч просмотров и под тысячу закладок. Я тогда уверенно заявил: REALITY не отличить от обычного HTTPS, поэтому он держится там, где всё остальное давно отвалилось. Прошло полгода — и оказалось, что я был прав ровно наполовину.В феврале ТСПУ перешёл на поведенческий анализ, а в июне — на то, что в чатах называют «заморозкой по fingerprint». И тут... Read more

A trio of major studies found that finerenone may protect the kidneys and heart in far more people than previously thought. The drug significantly slowed kidney disease progression and reduced the risks of kidney failure, heart failure, cardiovascular death, and overall mortality. Researchers saw benefits not only in patients with diabetes but also in those with non-diabetic kidney disease, a group with limited treatment options. Read more

A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a lower risk of developing dementia, while higher nitrate and nitrite intake from red meat, processed meat, and even drinking water was linked to a greater risk.

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together in a timeless "block universe." The argument suggests that physicists may be blurring the difference between things that exist and things that merely occur, creating deep confusion about what space-time actually is. Read more

Scientists have uncovered a key brain signal that helps us break old habits and adapt when circumstances suddenly change. By watching mice navigate a virtual maze, researchers found that disappointment—when an expected reward failed to appear—triggered a surge of the neurotransmitter acetylcholine, making the animals more likely to try a new strategy. When acetylcholine was blocked, the mice became less flexible and were more likely to stick with outdated choices. Read more
