This study evaluates blue-LIRIC (400-405 nm femtosecond laser) treatment on rabbit corneas, demonstrating that lower repetition rates (8.3 MHz vs 80 MHz) achieve greater optical phase change while avoiding tissue ablation, with collagen denaturation confirmed through histological and TEM analysis.
A technical FAQ on reversible cryopreservation technology that reviews the current state of the science—from successful preservation of human embryos (with over a million live births) and C. elegans to recent rat kidney cryopreservation—and maps the scaling challenges to preserve larger human organs. The article contextualizes cryopreservation as a way to 'buy time' for patients awaiting medical treatments that may become available in the future.
