A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up dramatically — but stem cells became less resilient over time. The work suggests aging may reflect a survival trade-off rather than straightforward decline.

Three YouTube channels have banded together and filed a class action lawsuit against Apple, as first spotted by MacRumors. According to the lawsuit, the creators behind h3h3 Productions, MrShortGameGolf and Golfholics have accused Apple of violating the Digital Millennium Copyright Act by scraping copyrighted videos on YouTube to train its AI models. While the YouTubers' videos are available to watch on the platform, the lawsuit alleged that Apple illegally circumvented... Read more ›

NASA's Artemis II crew just set a new distance record in miles traveled away from Earth. The team of four astronauts are in the process of circling the Moon, reaching 5,000 miles beyond the natural satellite. That brings the total distance traveled away from our home to over 250,000 miles. Gene Roddenberry would be proud. This broke the previous 1970 record set by Apollo 13's crew by around 4,000 miles.... Read more ›

An anonymous reader quotes a report from KrebsOnSecurity: An elusive hacker who went by the handle "UNKN" and ran the early Russian ransomware groups GandCrab and REvil now has a name and a face. Authorities in Germany say 31-year-old Russian Daniil Maksimovich Shchukin headed both cybercrime gangs and helped carry out at least 130 acts of computer sabotage and extortion against victims across the country between 2019 and 2021. Shchukin... Read more ›

Если говорить о производительности вне существующих решений в железе, то интуиция будет подсказывать достаточно простую модель выполнения, когда процессор обрабатывает инструкции, а память поставляет данные, и чем быстрее и то и другое, тем быстрее работает программа. Но процессоры научились выполнять миллиарды операций в секунду, а память наращивает скорость доступа намного медленнее, и разрыв между скоростью вычислений и доступа к данным стал настолько большим, что именно ожидание памяти, превратилось в г Read more ›

Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind this process, uncovering a delicate feedback loop in which sleep boosts growth hormone, and that same hormone helps regulate wakefulness.

Scientists at the University of Waterloo have uncovered a bold new way to explain how the universe began—one that could reshape our understanding of the Big Bang. Instead of relying on patched-together theories, their approach shows that the universe’s explosive early growth may arise naturally from a deeper framework called quantum gravity. Read more ›

A breakthrough urine test could dramatically speed up how doctors treat urinary tract infections, identifying the right antibiotic in under six hours instead of waiting days. By testing directly from urine—skipping the usual lab culturing step—the method quickly shows which drugs stop bacterial growth and which don’t. In trials involving hundreds of patient samples, the test proved highly accurate, matching standard methods in over 96% of cases. Read more ›

Perovskite crystals can dramatically and reversibly change shape when hit with light, a behavior not seen in conventional semiconductors. This effect, called photostriction, can be finely tuned depending on the light’s intensity and color. Researchers say these materials act more like adjustable systems than simple switches. The finding could lead to a new generation of light-powered sensors and devices. Read more ›

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in these systems, researchers can now measure motion and forces with unprecedented precision. This advance could unlock new ways to study gravity, probe quantum physics, and even revolutionize navigation with ultra-accurate, satellite-free systems. Read more ›

A new shape-shifting material can change both its texture and color in seconds, inspired by the camouflage abilities of octopuses. By precisely controlling how a polymer swells with water, researchers can create detailed, reversible patterns at the nanoscale. The material can even mimic realistic surfaces and dynamically adjust how it reflects light. In the future, AI could allow it to automatically blend into its surroundings. Read more ›

Scientists have uncovered a surprising secret about our DNA: it’s not a static blueprint, but a constantly shifting, folding structure that helps control how genes turn on and off. Researchers at the Salk Institute found that different parts of the genome loop and unloop at different speeds, with more active regions constantly reshaping themselves to support gene activity.

Salt substitutes offer a simple, low-cost way to reduce sodium intake and improve blood pressure, yet very few Americans actually use them—even among those who need them most. A large national analysis spanning nearly two decades found that usage remains surprisingly low and has not improved over time. Researchers say this gap represents a major missed opportunity for preventing heart disease and stroke. Read more ›

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining them with DNA folding techniques, scientists are creating structures that can move and act with precision. These robots can be guided using chemical reactions or external signals like light and magnetic fields. Read more ›

A surprising breakthrough suggests that a drug best known as Viagra could help treat a devastating childhood disease. Researchers found that sildenafil significantly improved symptoms in patients with Leigh syndrome—a rare and often fatal disorder that affects the brain and muscles. In a small study, patients showed stronger muscles, fewer seizures, and better recovery from dangerous metabolic crises, with some experiencing dramatic improvements in mobility and daily life.
