Lensless holographic microscopy replaces imaging optics with computation, but its classical Gabor principle has long been confined to thin, weakly scattering specimens. Researchers at Warsaw University of Technology have now pushed the method into the multiple-scattering regime. Near-infrared illumination preserved resolvable information through tissue-like scattering layers up to 1.4 mm, while increasing the sample-sensor distance unexpectedly doubled lateral resolution—revealing a new acquisition strategy for high-throughput, robust, amplitude-and-phase imaging in complex media.

Respiratory disease in children is a significant public health concern. Conventional assessments require in-person clinic visits and specialized equipment. Smartphones, on the other hand, could be practical for home-based screening. However, existing models trained on electronic-stethoscope data face challenges when applied to smartphone audio. In a new study, researchers developed a domain-adaptive deep learning framework that adapts information from electronic-stethoscope recordings to smartphone audio, supporting smartphone-based abnormal lung sound detection with potential for remote screening. 

Aston University researchers have contributed to an AI adoption and evaluation guidance to help legal organisations assess, implement and increase the use of artificial intelligence with more confidence and clarity.

Infrared adaptive optical systems that correct aberrations via deformable mirrors are critical for astronomy, defense, and industry fields. To this end, scientists in China invented a chain‑ring dual‑network chalcogenide glass that combine broadband infrared-transparent with polymer-like flexibility, which overcomes the long-standing material trade-off. Based on this novel material, they fabricated infrared deformable lenses with real‑time aberration correction, opening new pathways for infrared adaptive optical technology.

Tomomichi Itoh and his colleagues at Ehime University have shown how tiny light-induced molecular shape changes can be amplified into visible deformation of polymer microparticles. The team developed light-responsive particles containing azobenzene molecules and revealed how structural changes triggered by light spread through the material, ultimately deforming particles several to tens of micrometers in size. These findings provide new insights for designing light-driven microscale materials and devices.
