First 'perovskite camera' can see inside the human body

news.ycombinator.com Unknown 2025-09-24 11:49:08

Physicians rely on nuclear medicine scans, like SPECT scans, to watch the heart pump, track blood flow and detect diseases hidden deep inside the body. But today’s scanners depend on expensive detectors that are difficult to make. Now, scientists led by Northwestern University and Soochow University in China have built the first perovskite-based detector that can capture individual gamma rays for SPECT imaging with record-breaking precision. The new tool could make common types of nuclear medic

The biggest announcement coming out of the iPhone 17 series' launch event earlier this week wasn't about the most powerful iPhone yet -- it was for the thinnest. At 5.6mm, or less than a quarter of an inch, the iPhone Air stole the show. And even though it was far from the first mainstream "thin phone," it may just kick off the trend in a major way in the years to come.

When a comet meets solar winds, its nuclear coma—a bright cloud of gas around its core—reacts vibrantly to our Sun’s solar maximum, leaving a trail of stellar gas and dust across the solar system. Miraculously, the sky above June Lake, California, cleared up for a full 13 minutes for photographer Dan Bartlett to image the comet clearly enough for his photograph, “Comet 12P/Pons-Brooks Taking a Final Bow.” With incredible technological advances, the continuous flow of space photos can sometimes

Physicists Made a Time Crystal We Can Actually See

Of all the eccentricities of the quantum realm, time crystals—atomic arrangements that repeat certain motions over time—might be some of the weirdest. But they certainly exist, and to provide more solid proof, physicists have finally created a time crystal we can actually see. In a recent Nature Materials paper, physicists at the University of Colorado Boulder presented a new time crystal design: a glass cell filled with liquid crystals—rod-shaped molecules stuck in strange limbo between solid

The moment a cyberattack strikes, the clock starts ticking. Files lock up, systems stall, phones light up and the pressure skyrockets. Every second counts. What happens next can mean the difference between recovery and catastrophe. In that moment, you need three things above all else: clarity, control and a lifeline. Without them, even the most experienced IT team or managed service provider (MSP) can feel paralyzed by confusion as damage escalates. But with clarity, control and a lifeline, you
