China introduced a 35 µg m⁻³ annual PM₂.₅ limit in 2012 and later cut population-weighted exposure from 62.8 to 29.7 µg m⁻³ between 2013 and 2024 through clean air actions. Yet major economies and the ...
Images, videos, files: every day, we generate enormous amounts of digital data, a volume that is growing rapidly with the rise of artificial intelligence. How can we preserve this data over the long ...

Although the main prey of spotted hyenas (Crocuta crocuta), migratory ungulates such as blue wildebeest (Connochaetes taurinus), now spend substantially less time within hyena territories than they ...
RNA polymerases usually use a DNA or RNA template to direct synthesis. Other enzymes add nucleotides to the end of an existing RNA molecule. Could a protein instead assemble an RNA chain directly from ...
Biological clocks coordinate the spatiotemporal organization of metabolism with diurnal time cues, and bulk-tissue RNA sequencing studies in mammals have revealed widespread circadian (about 24 h) ...
