[:es]Geoengineers inch closer to Sun-dimming balloon test[:]
[:es]For years, the controversial idea of solar geoengineering—lofting long-lived reflective particles into the upper atmosphere to block sunlight and diminish global warming—has been theoretical. It’s starting to get real: Today, after much technical and regulatory wrangling, Harvard University scientists are proposing a June 2021 test flight of a research balloon designed to drop small amounts…

[:es]‘The game has changed.’ AI triumphs at solving protein structures[:]
[:es]Artificial intelligence (AI) has solved one of biology’s grand challenges: predicting how proteins curl up from a linear chain of amino acids into 3D shapes that allow them to carry out life’s tasks. Today, leading structural biologists and organizers of a biennial protein-folding competition announced the achievement by researchers at DeepMind, a U.K.-based AI company.…

[:es]Microbes’ mystery DNA helps defeat viruses—and has genome-editing potential[:]
[:es]Seven years ago, an understanding of nature inspired a revolutionary new technology, when researchers turned a defense system used by bacteria to thwart viruses into the gene-editing tool now known as CRISPR. But for another emerging gene editor the understanding has lagged the applications. For several years, researchers have been adapting retrons—mysterious complexes of DNA,…

[:es]The Maya built the Western Hemisphere’s first water filtration system[:]
[:es]The Maya city of Tikal is famous for its soaring palaces and temples. But something far more humble kept Tikal functioning: its water filtration system, the earliest known of its kind. Researchers recently discovered a volcanic mineral that captures microbes and heavy metals in one of Tikal’s largest reservoirs. Because the material is not found…
