Authors analysed genome-wide data from 4,587 ancient individuals against four models of Celtic origin and favour a movement from eastern central Europe as the most parsimonious.
A study in The Astrophysical Journal found that dwarf galaxies retain only a small fraction of the oxygen their stars produce, far less than simulations predict.
Authors report a physics-based starlight subtraction method tested on real JWST NIRCam data. It reduces dependence on the stability of reference images.
Two Nature studies by a team from Copenhagen and Leiden analysed DNA of over 4,500 ancient individuals; the authors tie migrations to the spread of Germanic and Celtic languages.
Barcelona-based Titan OS raised €40 million ($46 million) from Highland Europe, Mangrove and a BlackRock credit facility for its independent Linux-based smart TV OS.
In blood samples from 34 patients with systemic lupus erythematosus, Nature authors found 271 splicing events absent in controls; peptides from them activated T cells in vitro.
Orbital Matter says its 13 kg demonstrator printed a rigid beam in vacuum and helped unfold a solar module. Load capacity data are not yet published.
Italian teams (Niguarda, IFOM, INGM) linked early-onset colorectal cancer to reactivated HERVH sequences; in organoids, ATR inhibitors reduced viability. The result is preclinical.
Spanish researchers placed 219 engineered circuits of four types in bacteria and found that chromosomal position alone modulates performance and switches dynamics, via expression noise.
Amsterdam-based Return plans to install at least 1 GW of battery storage a year in Germany from 2027. The first framework covers three projects with a combined 117 MW.
Satellite records since 2001 show planted forests in temperate regions burned more often and over larger areas, but the effect varied by biome, from a near-threefold rise to an 18% drop.
Aluminum projectiles hit a diamond composite at up to Mach 8.45; parts of it turned to graphite within microseconds, dispersing impact energy, the authors report.
The first low-floor passenger train on hydrogen fuel cells has been assembled at Demikhovo and moves to testing. It is intended for non-electrified lines on Sakhalin.
Astrophysicists measured the deuterium-to-hydrogen ratio in the methane of 3I/ATLAS and found it about 13 times that of comet 67P. The exact age remains uncertain.
Portuguese and UK groups deleted the EMC3 subunit in mouse and Drosophila tissues. Lipid droplet homeostasis was disrupted and levels of the protein FITM2 fell.
Molecular dynamics of Trp-cage cooled at seven rates, the slowest matching experiment, found small but observable population shifts and a way to correct them.
Authors showed that endosomal Gs/cAMP signaling from one activated receptor outweighs concurrent plasma membrane RhoA activation, and in parathyroid cells suppresses hormone secretion.
Researchers at the Chinese University of Hong Kong compared stool microbiomes of 720 children with ASD and 151 controls. Associations with severity were significant but explained little variance.
In mice, deleting IRE1α or XBP1 in hepatocytes worsened liver metastasis, while the IRE1α inhibitor MKC8866 did not control metastases in the liver.
Multi-year measurements in four ocean regions show that precipitation below cloud base depends on cloud type, not only on liquid water content.
