Light-programmed system projects 28-layer 3D images in single shot

Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a passive diffractive optical decoder, jointly optimized end-to-end through deep learning. The hybrid architecture projects multiple distinct images onto closely spaced axial planes in a single shot, marking a significant step toward compact, high-fidelity volumetric display technologies. The research is published in the journal Light: Science & Applications.

3D image display technology is essential for next-generation holography, immersive visualization, and augmented and virtual reality (AR/VR) interfaces, where accurate focal cues across depth are critical for natural depth perception and visual comfort. However, dense depth multiplexing in conventional holographic displays remains a challenge: As the axial image planes approach one another in the output volume, diffraction-induced crosstalk rapidly degrades depth selectivity and image fidelity.

Supercomputer illuminates subatomic particle that helps hold matter together

A team of researchers has leveraged a supercomputer at the U.S. Department of Energy’s (DOE) Argonne National Laboratory to reveal the internal structure of a pion in unprecedented detail. The findings are published in the Journal of High Energy Physics.

Pions are subatomic particles that help bind matter at some of the smallest scales in nature. They are closely connected to the strong nuclear force, the fundamental force that holds protons and neutrons together inside atomic nuclei. Understanding how pions work can help scientists explain how matter forms at its most fundamental level.

“Pions mediate the strong force that binds nucleons—that is, the protons and neutrons that account for an atom’s mass,” said Yong Zhao, an Argonne physicist and principal investigator on the project.

Unique chromium beam experiment unlocks cosmic ray origins and galactic chemistry

When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them encounter manmade detectors. Recording how many of each of these elements show up helps scientists better understand cosmic processes—but despite incredible research advances over the last century, uncertainty around how these elements transform as they travel across the light-years has left fundamental questions about our galaxy’s composition unanswered.

Priyarshini Ghosh, a UMBC nuclear physicist with the Center for Space Sciences and Technology, is at the forefront of research that could significantly improve our understanding of these cosmic phenomena.

Ghosh and her collaborators have just completed a pioneering experiment at the Facility for Rare Isotope Beams (FRIB) at Michigan State University, where they generated and then fragmented a beam of chromium-52 nuclei. Chromium-52 is of particular interest because it can shed light on different processes happening in our galaxy, and yet it has never been measured.

Scientists Mapped Every Neuron in a Fruit Fly and the Brain Wasn’t Running the Show

Scientists have created the first complete brain-to-body wiring map of a fruit fly, revealing that complex behavior may arise from distributed neural teamwork rather than a central controller. A large international research team led by labs at Harvard Medical School and Princeton University has r
