  • Identifying jets originating from heavy quarks plays a fundamental role in hadronic collider experiments. In this work, the ATLAS Collaboration describes and tests a transformer-based neural network architecture for jet flavour tagging based on low-level input and physics-inspired constraints.

  • Although cellulose is abundant in the biosphere, its potential as a source of biofuel depends on finding efficient ways to degrade it. Blifernez-Klassen et al. show that phototrophic microalga Chlamydomonas reinhardtiican metabolize cellulose, indicating its potential as a catalyst for biofuel production.

  • Analyses of 475 ancient horse genomes show modern horses emerged around 2200 bce, coinciding with sudden expansion across Eurasia, refuting the narrative of large horse herds accompanying earlier migrations of steppe peoples across Europe.

  • An analysis involving the shotgun sequencing of more than 300 ancient genomes from Eurasia reveals a deep east–west genetic divide from the Black Sea to the Baltic, and provides insight into the distinct effects of the Neolithic transition on either side of this boundary.

  • Integrated data, including 100 human genomes from the Mesolithic, Neolithic and Early Bronze Age periods show that two major population turnovers occurred over just 1,000 years in Neolithic Denmark, resulting in dramatic changes in the genes, diet and physical appearance of the local people, as well as the landscape in which they lived.

  • Entanglement was observed in top–antitop quark events by the ATLAS experiment produced at the Large Hadron Collider at CERN using a proton–proton collision dataset with a centre-of-mass energy of √s  = 13 TeV and an integrated luminosity of 140 fb−1.

  • The ATLAS Collaboration reports the observation of the electroweak production of two jets and a Z-boson pair. This process is related to vector-boson scattering and allows the nature of electroweak symmetry breaking to be probed.
