Deep in the heart of our galaxy lies one of the most chaotic and mysterious regions in space. Now, scientists have created the first detailed map of magnetic fields in this turbulent zone, providing crucial insights into how stars form and evolve in extreme environments.

The research, led by University of Chicago Ph.D. student Roy Zhao, focused on a region called Sagittarius C, located in the c near the center of the Milky Way...

A new study reveals that fragmented sleep causes cellular damage to the brain’s blood vessels, providing further evidence to suggest that sleep disruption predisposes the brain to dementia.

The research, published in the journal Brain, is the first to offer cellular and molecular evidence that sleep disruption directly causes damage to brain blood vessels and blood flow.

“We found that individuals who had more fragmented sleep, such as sleeping restlessly and waking up a lot at night, had a change in their balance of pericytes—a brain blood vessel cell that plays an important role in regulating brain blood flow and the entry and exit of substances between the blood and the brain,” said Andrew Lim, principal investigator of the study and a sleep neurologist and scientist at Sunny...

Scientists at the Institute for Photonic Quantum Systems (PhoQS) and the Paderborn Center for Parallel Computing (PC2) at Paderborn University have developed a powerful open-source software tool that allows them to simulate light behavior in quantum systems.

The unique feature of this tool, named “Phoenix,” is that researchers can use it to very quickly investigate complex effects to a level of detail that was previously unknown, and all without needing knowledge of high-performance computing. The results have now been published in Computer Physics Communications.

Phoenix solves equations that describe how light interacts with material at the quantum level, which is essential for under...

A new paper reveals that ground acceleration from moonquakes, rather than meteor impacts, was responsible for shifting lunar landscapes at the moon’s Taurus-Littrow valley, where Apollo 17 astronauts landed in 1972. The study also pinpointed a possible cause for those surface changes and assessed damage risk using new models of the quakes—findings that may impact the safety of future lunar missions and the establishment of long-term bases on the moon.

The paper, authored by Smithsonian Senior Scientist Emeritus Thomas R...
