"Quantum-Inspired Imaging Breakthrough Unveils Hidden Details Amidst Noise"

Researchers have developed a new quantum-inspired phase imaging method that is resistant to phase noise and can function in low-light conditions. This technique, which utilizes light intensity correlation measurements, is poised to enhance imaging in medical research, art preservation, and other fields that require high precision imaging under challenging conditions. The method's robustness to noise and ability to operate with dim illumination could revolutionize phase imaging applications, including infrared and X-ray imaging, as well as quantum and matter-wave interferometry. The research has been published in Science Advances and promises to open up new possibilities in various scientific domains.

"Tonga's Merging Magma Chambers: A Volcanic Eruption Waiting to Happen"

Scientists have mapped the magma system beneath the Hunga Tonga-Hunga Ha'apai volcano, revealing that the massive 2022 eruption was likely caused by the merging of two magma chambers. The eruption, which was the most intense lightning storm ever recorded and triggered a mega tsunami, ejected about 30% of the magma from a shallow chamber, forming a caldera. Despite the eruption, up to 6.2 cubic miles of eruptible magma may still be present beneath the volcano. The study, published in Science Advances, used gravity variations to image the magmatic system, a rare approach for submarine volcanoes. The findings help understand the volcano's structure but do not pinpoint the eruption's trigger.
