Scientists may have found a way to make old cells act young again
Scientists have discovered that old cells lose their coordinated gene activity. By resetting these internal control systems, researchers made aged human cells behave like younger ones. This approach showed promise in mice, improving liver function. The findings suggest a future where age-related decline could be slowed or reversed by fixing cellular organization, not replacing cells.
Why NASA releases half million gallons of water before every rocket launch
NASA's massive water deluge system, releasing nearly 450,000 gallons, is crucial for rocket launches. This powerful spray controls extreme sound, vibration, and heat generated at ignition, preventing catastrophic damage to the rocket and launchpad. Lessons learned from past missions underscore its vital role in ensuring successful liftoffs.
ChatGPT ‘nearly kills’ woman after giving confident advice about a poisonous plant
A YouTuber has warned of the dangers of trusting AI after ChatGPT repeatedly misidentified poison hemlock as harmless carrot foliage, nearly putting her friend at risk. Despite visual evidence, the chatbot doubled down with confident reassurances. The incident highlights how AI errors, especially in health and safety contexts, can have serious real-world consequences.
