It has been discovered for the first time that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether the solid oxide cell is generating electricity or producing hydrogen. This finding introduces a new design principle for improving the performance of next-generation solid oxide cells.

Herein, we report a user-friendly electrocatalytic glycosylation strategy that employs stable and readily available acetyl glycosides as glycosyl donors. The reaction proceeds at room temperature and ambient pressure in an undivided electrolytic cell, enabling rapid access to structurally diverse O‑, S‑, and N‑glycosides, as well as disaccharides, with moderate to excellent diastereoselectivity. The lithium perchlorate/acetonitrile electrolyte system was identified as the optimal reaction medium. Mechanistic studies reveal that a Brønsted acid generated in situ at the anode activates the C–O bond of the acetyl glycosides, thereby initiating the glycosylation process. This method features exceptionally broad substrate scope, excellent functional group tolerance, requires only a catalytic amount of charge (0.1 F/mol), and reaches completion within 10 minutes.

Data Release 20 (DR20) delivers more than two million spectra from twin observatories, revealing the chemical origins, stellar collisions, and ancient structure of the Milky Way

A team led by Penn State researchers has developed a synthetic mimic of an enzymes that drives an enzyme-like reaction, requiring only oxygen and producing only water as waste.

As part of Data Release 20 (DR20) of the fifth phase of the Sloan Digital Sky Survey (SDSS-V), astronomers are releasing a public preview of the Local Volume Mapper (LVM).

An international team led by Prof. LIU Yi from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences investigated how CH₄ emissions in Siberia are evolving under climate change, showing how atmospheric circulation promotes wildfire activity and methanogenesis and thereby drives the recent sharp rise in CH₄ emissions.

Movement is a central aspect of almost every animal’s survival, whether it relates to local exploration or global migration. Even more sophisticated behaviors, such as the collective interactions for which many types of ants are famous, are built upon the motion of the individual. As such, understanding this individual behavior is integral to piecing together the life and ecology of an animal. By recording how individual ants explore a laboratory environment, researchers have come up with a model for how these ants navigate based on stochastic physics. As one of the most rigorous descriptions of ant exploration behavior to date, this model allows researchers to explore how these ants might behave in new environments, and highlights how physics-based tools and models can be used to quantify and understand living systems.
