877 Your DNA has a secret “second code” that decides which genes get silenced

ScienceDaily
ScienceDaily 2 place · 04/09/2026 04:32 EDT

Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence them. A protein called DHX29 plays a key role in this process by identifying and suppressing weaker messages. This finding reveals a hidden layer of control in how genes are used.

Fears mount that PlayStation has "re-armed the CBOMB" issue which stops you playing purchased games, amid 30-day DRM and AI chat bot confusion

PlayStation users have discovered an issue whereby some digital games become unplayable unless an online connection is made every 30 days - although further community digging suggests it seems to be only a one-off, temporary form of digital rights management (commonly known as DRM).

[Перевод] Проблемы санации SVG

Рендерер Scratch имеет долгую историю связанных с SVG уязвимостей. Их источником становится то, что Scratch парсит сгенерированный пользователем (то есть контролируемый нападающими) контент в элемент  и добавляет его в основной документ для выполнения различных операций (например, для измерения ограничивающего прямоугольника SVG более надёжным образом, чем viewbox или width/height).Даже если SVG остаётся в основном документе очень недолго, это небезопасная по своей природе операция. Для обеспечения защиты S Read more

Началось: РКН запустил автоматический бот по сайтам — проверки ужесточили, предпринимателям массово шлют предписания

Осенью 2025 года заработал новый закон о персданных. Ввели новые требования и штрафы, достигающие 15 000 000 рублей.И если в ноябре того года «письма счастья» были единичными, то теперь РКН запустил автоматический бот и проверки стали массовыми. Я как юрист уже успел насмотреться всякого от РКН. Давайте на примере реальных предписаний разберем, как проверить себя и свою компанию, чтобы не влететь. Читать далее Read more

A routine blood marker tied to inflammation may reveal Alzheimer’s risk years in advance. Scientists found that higher neutrophil levels—part of the body’s first immune response—were linked to a greater chance of developing dementia. The discovery suggests this common lab value could help flag at-risk individuals before symptoms appear. It also raises the possibility that immune cells themselves may be fueling the disease.

A newly discovered virus hiding inside a common gut bacterium could help explain one of medicine’s long-standing mysteries: why a microbe found in both healthy people and cancer patients is linked to colorectal cancer. The research suggests that the interaction between bacteria and the viruses they carry may be key to understanding disease risk. It may even lead to future screening tests that detect cancer risk earlier. Read more

Scientists at UC Irvine have found a way to potentially reverse age-related vision loss by targeting the ELOVL2 “aging gene” and restoring vital fatty acids in the retina. Their experiments in mice show that supplementing with specific polyunsaturated fatty acids—not just DHA—can restore visual function and even reverse cellular aging signs. Read more

Scientists have mapped how Earth’s deepest mantle is being deformed—and the results point to long-lost tectonic plates buried thousands of kilometers underground. Using a massive global dataset of seismic waves, they found that most deformation happens in regions where these ancient slabs are thought to reside. The findings confirm long-standing theories but, for the first time, show the pattern on a global scale. It’s a major step toward understanding how... Read more

A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient. Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time. Unlike conventional chips that waste energy moving data back and forth, this device operates with ultra-low power—potentially slashing energy use by up to 70%. Read more

A new minimally invasive procedure may help people keep weight off after stopping popular drugs like Ozempic and semaglutide—something most patients struggle with. In a clinical trial, those who underwent a technique called duodenal mucosal resurfacing regained far less weight compared to others after discontinuing the medication. The procedure works by renewing the lining of the upper small intestine, potentially “resetting” metabolism and preserving the benefits of weight loss. Read more

By analyzing donated brain tissue with advanced genetic tools, the researchers found changes in neurons linked to mood and stress, as well as in immune-related microglia cells. These differences point to disruptions in key brain systems and reinforce that depression is rooted in... Read more
