Genome-wide ancient DNA data from individuals from the Middle Bronze Age to Iron Age documents large-scale movement of people from the European continent between 1300 and 800 bc that was probably responsible for spreading early Celtic languages to Britain.
Studies using neural ensemble recordings in rats show that cells in the piriform cortex carry a spatial representation of the environment and link locations to olfactory sensory inputs.
A mechanism involving intracellular recycling of the morphogen Decapentaplegic (Dpp) underlies the scaling of the Dpp gradient in the Drosophila wing disc, and this is modulated by the extracellular factors Pentagone and Dally.
Intra- and inter-specific grafting is possible in most orders of monocotyledonous plants, and this process could be used to combat diseases that affect crops, such as Panama disease in bananas.
Two very-high-frequency quasi-periodic oscillations (at 2,132 Hz and 4,250 Hz) are detected within the initial hard spike of a magnetar giant flare originating from the galaxy NGC 253, and detailed temporal and spectral analyses are performed.
The cryo-electron microscopy structure of the glucocorticoid receptor (GR)-loading complex—a complex in which Hsp70 loads GR onto Hsp90 and Hop—is described, providing insights into how the chaperones Hsp90 and Hsp70 coordinate to facilitate GR remodelling for activation.
Microbial methanogenesis converts up to 19% of the carbon dioxide injected into an oil field to methane, suggesting that microbial methanogenesis may be a globally important subsurface process.
Studies based on cryo-electron microscopy structures of Hsp90 chaperone complexes reveal the molecular mechanism of the chaperone-mediated maturation of the human glucocorticoid receptor.
The reported network of connectivity between atomic ensembles is entirely programmable and independent of its geometrical arrangement, because of the interaction with an optical cavity.
A study reports and characterizes a high-entropy electrocaloric polymer that switches under low fields, and discusses its potential suitability for use in caloric heat pumps.
An analysis of cancer mortality data for zoo mammals highlights marked differences across mammalian orders and an influence of diet, and shows that mortality risk is largely independent of body mass and life expectancy across species.
An electrochemical process stimulates the progression toward the electrode of isolated or ‘dead’ lithium in a battery, recovering its electrical connection, and the effect is demonstrated by increased cycle life.
Inelastic neutron scattering measurements show that superconductivity in UTe2 is associated with a resonance near antiferromagnetic order that suggests an unexpected spin-singlet component to the electron pairing.
Unphosphorylated PINK1 of Pediculus humanus corporis forms a dimerized state before undergoing trans-autophosphorylation, and phosphorylated PINK1 undergoes a conformational change in the N-lobe to produce its phosphorylated, ubiquitin-binding state.
By tracing the changing size of ostrich eggshell beads, climate is shown to have an important role in influencing when and where regional African populations interacted.
Studies using viral coat glycoproteins show that alphaviruses can enter cells via the very low-density lipoprotein receptor (VLDLR) and apolipoprotein E receptor 2 (ApoER2), members of an evolutionarily conserved family of lipoprotein receptors.
