A research team has reviewed the crucial role of light-dependent protochlorophyllide oxidoreductase (LPOR) in chlorophyll synthesis and chloroplast development, particularly during the dark-light transition in plants.
Revealing the underlying patterns behind complex systems and predicting their behavior has become a focal point of current interdisciplinary research. In this study, researchers delved into the intrinsic mechanisms of complex systems behavior of photonic phase transitions in one-dimensional Rayleigh scattering systems by establishing a Rayleigh-scattering-phase-variation model with experimental realization. This work expands the current understanding of photonic phase transitions, which is an important reference value for the study of various complex systems. Furthermore, it advances the application of random fiber lasers in critical fields such as high-power laser devices.
Measuring computer chips to identify defects during manufacturing is crucial to improve production yield. Scientists from Delft and Utrecht investigated a novel imaging technique using EUV light—a high-energy short-wavelength radiation—to examine the 3D nanoscale structures on the chips. This technique eliminates the need to use any imaging system containing expensive EUV reflective mirrors in the measurement tool. Instead, images are reconstructed computationally from acquired diffraction data, resulting in a significant cost reduction.
Photothermoelectric (PTE) detectors have garnered substantial research interest for their promising capabilities in broadband self-driven photodetection. To get higher performances, it is crucial to localize light and heat energies for efficient conversion. Therefore, scientists in China fabricated a three-dimensional (3D) tubular detector by nanomembrane self-rolling, and remarkably enhanced performance has been achieved. The proposed self-rolled device holds promise for next-generation on-chip photodetection.
A long-wave, high-power, wide-tunable, single-longitudinal-mode solid-state laser was designed as light source in photoacoustic gas detection technology. The laser emits at ~2 μm with an excellent wavelength and power stability.
Sepsis survivors remain at significant risk for readmission, with unexpectedly high rates of returning to the hospital for those discharged to home health care or home settings, according to a study published in American Journal of Critical Care
The SGLT2 inhibitor empagliflozin confers kidney-protective benefits and can therefore be given safely and effectively to patients when they are hospitalized for acute myocardial infarction (MI), a Mount Sinai-led global team of researchers has shown.

This study suggests single-pixel detection as a cost-effective alternative to expensive InGaAs focal plane arrays (FPAs) for near infrared (NIR) hyperspectral imaging.
Colloidal quantum dots (CQD) are of interest for optoelectronic devices because of the wide energy gap tunability from ultraviolet to infrared wavelengths.
