Hidden Archimedes Page Emerges From French Museum Archive

Researchers from CNRS identified a long-lost Archimedes page tucked within a 13th‑century palimpsest in the Musée des Beaux‑Arts de Blois. The fragment sits beneath Byzantine prayers and contains geometric arguments related to On the Sphere and Cylinder. It was authenticated by matching with Johan Heiberg’s 1906 photographs, reviving interest in the Archimedes Palimpsest. Scientists plan multispectral imaging to reveal more of the hidden text.

Camera Lets Humans See Colors Beyond Our Spectrum

A high-tech camera system, developed by Vera Vasas and the Hanley Color Lab at George Mason University, records four color channels (blue, green, red, and UV) to render real-time videos of how different animals perceive color, translating photoreceptor data into perceptual units with over 92% accuracy versus traditional methods, and making animal-vision visualization practical for scientists and filmmakers using off-the-shelf cameras in a modular, 3D-printed setup.

Proteins in Margins Reveal Renaissance DIY Medicine

Researchers combined multispectral imaging and proteomics to study two 1531 Renaissance medical manuals, uncovering faded text and protein traces from readers’ hands. The marginalia show extensive at‑home experimentation with vernacular remedies, including both common ingredients and exotic compounds like hippopotamus teeth; proteomics also detected immune-related proteins, illustrating how Renaissance knowledge blended practical tinkering with book knowledge. The work demonstrates a new way to contextualize historical recipes and could scale to more collections.

Revolutionary tech reveals secrets of alfalfa seeds.

Scientists at China Agricultural University have used multispectral imaging technology to identify the characteristics of alfalfa hard seeds, which have low value and pose major challenges from an economic standpoint. The team found that alfalfa dormancy is structured by the PY+PD pattern, rather than the PY pattern alone, and that abscisic acid (ABA) responses played a key role in hard alfalfa seeds. The study provides a theoretical and technical framework for exploring alfalfa hard seed dormancy, which could guide the optimal processing of these seeds in the agriculture industry.
