"DESI, based at the Kitt Peak National Observatory near Tucson, Arizona, has measured the precise distances of 47 million galaxies and quasars. Pictured is a thin slice of the map, with the Milky Way at its centre; the inset shows how galaxies form a web of clusters and filaments under the pull of gravity. DESI's preliminary results hinted that the leading model of cosmic expansion could be wrong."

Last month, a cosmology project completed its initial five-year mission to create the most detailed 3D map of the Universe so far. The Dark Energy Spectroscopic Survey (DESI) has measured the precise distances of 47 million galaxies and quasars."
"Leisurely scroll 'Dark' portions of the genome, which weren't thought to hold instructions for making working proteins, have mostly been excluded from research. Now thousands of the proteins encoded by these genes have an official, new name - peptideins - that marks their inclusion in major gene and protein databases used by the life-sciences community. Dark proteins tend to be very short in amino acid length and lack evolutionary relatives in other organisms."
"A growing community of synthetic biologists using biotechnology-led solutions - mostly microorganisms containing DNA tailored for a specific function - to tackle pollution ranging from microplastics and industrial waste to soils laced with heavy metals or explosive residues. But the field is held back by concerns around releas"
DESI at Kitt Peak National Observatory near Tucson completed an initial five-year mission to build a detailed 3D map of the Universe. The survey measured precise distances for 47 million galaxies and quasars. The map shows a thin slice with the Milky Way at its center and illustrates how galaxies form a web of clusters and filaments shaped by gravity. Preliminary DESI results indicate that the leading model of cosmic expansion could be incorrect. Separate coverage notes that previously overlooked “dark” genomic regions have been linked to thousands of newly named peptideins, which are short proteins lacking evolutionary relatives but have roles in disease and cellular functions. Synthetic biology is also described as using engineered microorganisms to address pollution, while facing concerns about release.
