Physicists prove a long-suspected quantum speed limit for thermalization - Phys.org

No one would argue that the Ironman World Championship in Kona is physically taxing – but it goes well beyond the traditional post-Ironman fatigue due to the challenging conditions. Post-race, you’ll not only suffer physiological stress, but also nervous and digestive system stress, which can create brain fog and emotional volatility.

Ahead of Halloween, Zero Latency VR brought in "scientist of fear" Dr. Coltan Scrivner to explain why people can't stop playing with the things that scare them MELBOURNE, Australia, Oct. 2, 2026 /PRNewswire/ — Zero Latency VR, the world's largest and most innovative immersive VR network, is celebrating a double Halloween anniversary: three years since the launch of Outbreak, its free-roam zombie survival shooter, and one year since the debut of Haunted, its immersive haunted house experience. Rather than mark the occasion alone, the company brought in an outside expert: Dr. Coltan Scrivner, a research scientist who studies why humans seek out frightening things for fun.

Some quantum systems are so complex that even the most powerful supercomputers struggle to simulate their behavior. One solution is quantum simulation: building a controllable quantum system in the lab and tuning it to mimic the one researchers want to understand.

In optical fibers, chips and other light-guiding devices, minor defects can scatter photons and disrupt their path. A new study demonstrates a way to reveal properties which, in certain systems, help light wave behavior withstand such flaws. The method could help speed up the search for new kinds of electronics and optical technologies, and contribute to more reliable quantum devices.

Roman is designed to return about 1.4 terabytes of data daily, with observations becoming publicly available after processing. A collaboration of roughly 900 astronomers is preparing to search those observations for planets, black holes and cosmic explosions. The telescope’s surveys could sharpen measurements of dark energy, but their major discoveries still lie ahead. A distant star briefly brightens. A supernova appears in a galaxy. Somewhere else, an unseen object bends passing starlight. NASA’s Nancy Grace Roman Space Telescope is designed to capture such changes across crowded stretches of sky, then make its observations available for others to investigate. The challenge will be keeping up. Roman is expected to return about 1.4 terabytes of data daily during operations. Jessica Lu, an astronomy associate professor at the University of California, Berkeley, and David Weinberg of Ohio State University have organized a collaboration of roughly 900 astronomers to prepare. Their effort connects two ambitions: finding unusual objects in the Milky Way and understanding why the universe’s expansion is accelerating.
