Two stars spiraling toward catastrophe test Einstein’s gravity

Astronomers have observed a pair of stars trapped in a death spiral, and their dance of destruction reveals more about how gravity works. The system, called ZTF J2130, is located about 4,000 light years away. Astronomers have known about this system for some time, but this is the first time they’ve seen it so clearly. […]
The Future of Digital Twins in Healthcare: From Virtual Replicas to Personalized Medical Models

As artificial intelligence and real-time data streams converge, digital twins are poised to redefine the very foundations of modern healthcare. But everything changed in 2002, when researchers and industry leaders pushed for a more precise definition: a true digital twin must maintain continuous, bidirectional communication with its physical version. Real-time data became the lifeblood of […]
