Holographic Breakthrough: This New Futuristic 3D Imaging System Overcomes a Longstanding Problem for Holographic Tech
A new 3D image projection system from researchers at the UCLA Samueli School of Engineering and the California NanoSystems Institute (CNSI) marks a major step toward overcoming a longstanding problem for holographic technology.
Professor Aydogan Ozcan led the work reported in a recent paper published in Light Science and Applications, which describes the team’s new snapshot 3D image projection system, solving one of the technology’s most daunting issues.
“These results establish the diffractive 3D display system as a compact and scalable framework for depth-resolved snapshot 3D image projection, with potential applications in holographic displays, AR/VR interfaces, and volumetric optical computing,” the authors write.

Advancing Surgical Robotics with AI-Driven Simulation and Digital Twin Technology
Imagine a surgeon being able to “step inside” a digital version of a patient’s body — studying organs, tissues, and complex structures, rehearsing procedures, and evaluating possible approaches before performing the actual operation.
The integration of robotic surgical assistants (RSAs) in operating rooms offers substantial advantages for both surgeons and patient outcomes. Currently operated through teleoperation by trained surgeons at a console, these surgical robot platforms provide augmented dexterity that has the potential to streamline surgical workflows and alleviate surgeon workloads. Exploring visual behavior cloning for next-generation surgical assistants could further enhance the capabilities and efficiency of robotic-assisted surgeries.
This post introduces two template frameworks for robotic surgical assistance: Surgical First Interactive Autonomy Assistant (SuFIA) and Surgical First Interactive Autonomy Assistant – Behavior Cloning (SuFIA-BC). SuFIA uses natural language guidance and large language models (LLMs) for high-level planning and control of surgical robots, while SuFIA-BC enhances the dexterity and precision of robotic surgical assistants through behavior cloning (BC) techniques. These frameworks explore the recent advances in both LLMs and BC techniques and tune them to excel to the unique challenges of surgical scenes.
This research aims to accelerate the development of surgical robotic assistants, with the eventual goal of alleviating surgeon fatigue, enhancing patient safety, and democratizing access to high-quality healthcare. SuFIA and SuFIA-BC advance this field by demonstrating their capabilities across various surgical subtasks in simulated and physical settings. Moreover, the photorealistic assets introduced in this work enable the broader research community to explore surgical robotics—a field that has traditionally faced significant barriers to entry due to limited data accessibility, the high costs of expert demonstrations, and the expensive hardware required.

FOXO3: The Longevity Switch Inside Our Cells — Decoding the Master Regulator of Aging, Stress, and Disease
Aging is a universal biological process, yet the reasons why some individuals live significantly longer and healthier lives have long puzzled scientists. Among the genes linked to exceptional longevity, FOXO3 consistently stands out as one of the most influential “master controllers” of cellular resilience. This single transcription factor integrates signals from stress, metabolism, DNA repair, and stem cell biology, orchestrating a vast genetic program that determines how cells survive, adapt, or age [1].
In recent years, interest in FOXO3 has surged across aging research, regenerative medicine, oncology, and precision therapeutics. Variants of the FOXO3 gene are strongly associated with centenarian populations worldwide, while disruptions in its regulatory network contribute to multiple disorders, including cancer, neurodegeneration, metabolic decline, and tissue degeneration. With advances in computational biology and pathway analysis, it is now possible to map FOXO3’s complex signaling network and uncover new therapeutic strategies.
This blog post explores FOXO3’s multifaceted biological roles, its influence on disease, and what our curated data from TRANSFAC®, TRANSPATH®, and HumanPSD™ reveals about the FOXO3 regulatory network. The goal is to provide a scientifically rich yet accessible overview that sparks curiosity among researchers studying aging, longevity, and systems-level biology.
