The US Environmental Protection Agency (EPA), guided by President Joe Biden’s administration, introduced these legally binding regulations to protect communities from the detrimental impacts of […]

**New Mass Spectrometry Studies Question Water Microdroplet Chemistry** Recent studies by Ryan Julian and his team at the University of California, Riverside, challenge the previously accepted idea that water microdroplets can spontaneously produce hydroxyl radicals. This investigation indicates that trace ammonia contamination may be the cause of signals that were formerly identified as reactive hydroxyl […]

**StructureMASST: Revolutionizing Access to Public Metabolomics Data with Structure-Oriented Searching** The field of metabolomics is experiencing rapid expansion, with the public release of a variety of datasets increasing consistently. This increase brings forth a distinct challenge: efficiently exploring and leveraging raw mass spectra data. Although indexing technologies have accelerated search processes, existing methods struggle when […]

The idea of cell-cultured, or ‘lab-created’, chocolate is gaining traction amidst climate-driven supply chain challenges and a notable surge in cocoa prices. Researchers at the University of California, Davis are collaborating with the food technology firm California Cultured to create innovative bioreactors capable of growing plant cells, bringing this kind of alternative chocolate closer to […]
