Birds’ agile perching maneuvers allow large energy dissipation in short approach flights. Here, authors test an objective that birds are hypothesized to employ in perching maneuvers on an avian-inspired drone and find that it mimics the birds’ behavior, enabling exploration of key morphing actuations.

The GEOCARBSULF model provides the most detailed reconstructions of Phanerozoic O₂, but its predictions are not supported by geochemical data. Here, a GEOCARBSULF model rebuilt from first principles, with the addition of an amended sulphur cycle and the latest isotope records, supports a Paleozoic Oxygenation Event.

The rocky disk surrounding the young Sun may have experienced a close flyby of another star. Simulations show that a highly inclined flyby of a star slightly smaller than the Sun at 100 au almost perfectly reproduces the orbits of the numerous small objects beyond Neptune.

The initial steps of the ion solvation process are observed for the solvation of a single sodium ion in liquid helium, opening possibilities for benchmarking theoretical descriptions of ion solvation.

Fundamental theories do not predict a difference between the properties of matter and antimatter, but experimental tests of this are still in their infancy. To this end, this study analyses the effects of electric fields on antihydrogen atoms in the ALPHA trap to place a bound on the charge of antihydrogen.

The authors model the role of algal symbiont shuffling and evolution in coral resilience to warming and ocean acidification, globally. They find that shuffling is more effective than evolution, and show global patterns of vulnerability due to the interaction of warming rate and adaptive capacity.

One intriguing question about antimatter that is yet to be directly answered is whether or not it behaves exactly the same as matter under gravity. Here, a direct experimental method is presented to measure the ratio of inertial to gravitational mass for antihydrogen under free-fall conditions.

A high-resolution three-dimensional global climate model of Saturn captures the small-scale dynamics of its stratosphere. It is able to reproduce the observed semi-annual equatorial oscillation and finds evidence of an interhemispheric meridional circulation that can explain the periodicity of its equatorial oscillation and the seasonal behaviour of hydrocarbon abundances.

Antihydrogen has been created, trapped and stored for 1,000 s. The improved holding time means that we now have access to the ground state of antimatter—long enough to test whether matter and antimatter obey the same physical laws.

Winter sea ice is thought to provide critical grazing habitat for overwintering Antarctic krill. In contrast, here the authors show that the pack-ice zone is a food-poor habitat, but does serve as an important sheltering ground for developing larvae.

The FET family proteins FUS, EWSR1 and TAF15 are RNA-binding proteins with diverse nuclear functions. PAR-CLIP analyses now reveal the genome-wide RNA targets of all three human FET proteins and of two FUS mutants that cause amyotrophic lateral sclerosis. Although the RNA-binding properties of the mutants remain unchanged, the spectrum of RNA targets is altered because of the changed subcellular localization of the mutants.

Intrinsic randomness, also known as spontaneous stochasticity, has been suggested to limit the finite-time predictability of multiscale chaotic dynamics, but an explicit demonstration of its effect is still lacking. Here, the authors use numerical simulations to show the existence of spontaneous stochasticity in the discontinuous shear layer leading to the Kelvin-Helmholtz instability.

Models of thermochemical convection reveal flow patterns in the deep lower mantle under the north Pacific since 100 million years ago that explain how the enigmatic bend in the Hawaiian–Emperor hotspot track arose.

The measurement of the total cross-section of proton–proton collisions is of fundamental importance for particle physics. Here, the first measurement of the inelastic cross-section is presented for proton–proton collisions at an energy of 7 teraelectronvolts using the ATLAS detector at the Large Hadron Collider.

The U.S. Budyko water balance is influenced by snow fraction and irrigation, driving changes in aridity-streamflow dynamics, while deviations in Great Britain are driven by precipitation-streamflow dynamics, according to an analysis of 1,342 catchments.

The micronutrients iron and manganese are enriched in the Southern Ocean eastern Pacific sector at 2 to 4 km depth, probably from hydrothermal activity at ocean ridges, as revealed in depth profiles, and they could reach the surface mixed layer within two decades according to simulated water trajectories.

Bright solitary waves are wavepackets that propagate without dispersion and have been under intense investigation in a variety of settings, including Bose–Einstein condensates (BEC), with a view of realizing a matter-wave interferometer. The authors present experimental and theoretical results on a bright-matter-wave soliton from a BEC, and observe splitting and recombination at a barrier potential enabling them to place constraints on the barrier stability needed to implement soliton interferometry.

Genetic, molecular, and computational analyses reveal that salt stress alters root apical meristem size through miR165/166-mediated regulation of cytokinin levels via the PHB-IPT7 pathway.

Transcriptional alterations demonstrate that adipose tissue responded to exercise completely distinct from skeletal muscle in the same human subjects. Adipose tissue showed acute and repeated reduction in transcripts of lipid uptake, synthesis and storage. The data also suggest the restoration of a healthier circadian rhythm in adipose tissue of subjects with obesity after regularly performed exercise. The interconnection of circadian rhythm with lipid metabolism possibly contributes to improved metabolic health and prevention of diabetes.
