Scientists catch a hidden electronic state forming in just 30 femtoseconds
A hidden electronic state formed in a material in just 30 femtoseconds when triggered by light, with bonds reorganizing in a repeating pattern before atomic shifts occurred. This ultrafast pathway reveals a previously unseen step that could enable control of electronic properties with light.

A hydrogel platform using vitamin B2 and blue light enables researchers to create customized biomaterials for tissue engineering and drug discovery under cell-friendly conditions. The plug-and-play crosslinking technology allows incorporation of biological molecules including proteins, peptides, and nucleic acids into hydrogels.
Climate change could triple the price of wheat
Climate change could triple wheat prices by simultaneously causing water shortages across major wheat-growing regions in North America, Europe, and Asia. These shortages would increase costs for bread, pasta, and breakfast cereals on supermarket shelves.
Complex odors prove easier to map than expected with machine learning
A machine learning model can map complex odors using chemical composition data, similar to how the Pantone system categorizes colors. The researchers found that odor perceptions cluster predictably based on molecular properties, enabling systematic comparison between different scents.
