Phys.org / Trees and microbes team up to improve nitrogen nutrient processes in higher CO₂ conditions

Forest trees growing in air containing higher levels of carbon dioxide (CO2) radically change the way they "cycle" nitrogen, a key plant nutrient, with implications for forests as a nature-based climate solution.

Phys.org / Beyond wrinkles: New rule explains why growing shapes suddenly crumple

Scientists have discovered a previously unknown law of geometry that explains why some growing surfaces, whether in nature or in engineered materials, suddenly stop being able to stay smooth and instead form dimples and folds. ...

Phys.org / Two attosecond flashes capture electrons in motion

Electronic motion sets the stage for virtually every light-induced process in nature, from the first step of a chemical reaction to the flow of charge in a solid. Yet these processes unfold so rapidly that they can be observed ...
