The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

We report the outcome of an international optical observation campaign of a prototype constellation satellite, AST SpaceMobile’s BlueWalker 3, which features a 64.3 m² phased-array antenna and a launch vehicle adaptor.

The Earth’s bow shock results from the interaction of the solar wind with the terrestrial magnetic field. With global numerical simulations and spacecraft observations, the transmission of fast magnetosonic waves through the bow shock is revealed.

The transport properties of materials with topologically non-trivial band structures may be manipulated by an applied magnetic field or by magnetic doping. Here, the authors demonstrate quantum Hall states for temperatures up to 2 K in thin film bilayers comprising pristine and Cr-doped topological insulators.

Electromagnons are collective electric and magnetic excitations of electron spins. Here, the authors discover a strong magnetochiral dichroism in a magnet with helical spin order, where light at the electromagnon resonance is absorbed differently depending on its polarization and propagation direction.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Measurement of the bound-state β⁻ decay of ²⁰⁵Tl⁸¹⁺ gives a new, longer half-life, allowing for the calculation of accurate stellar ²⁰⁵Pb yields and the isolation time of the early Solar System.

The strength of the interaction between the spin state and orbital motion of electrons in a semiconducting quantum dot can be controlled by electrical gates.

Clatworthy and colleagues examine adult nasal lymphoid tissues in response to SARS-CoV-2 infection. Longitudinal profiling reveals changes in barrier tissue to block viral entry beyond the epithelial cell layer and how tissue repair occurred after viral infection.

In most van der Waals ferromagnets, reducing the number of layers reduces the Curie temperature. Here, Chuang et al., find that Cr₂Se₃ has an increased Curie temperature for thinner samples, and through angle-resolved photoemission spectroscopy they attribute this to differences in the valley carrier density in different thickness samples.

Devices that generate electricity from electric fluctuations are promising for wireless power transmission as well as energy harvesting from environmental radio waves. Here the authors report the electric power generation from environmental fluctuations by using superconducting vortex strings in MoGe/YIG bilayer system.

Iron pnictide compounds have recently been shown to have superconducting properties. Xuet al. show that the superconducting gap of underdoped pnictides scales linearly with the transition temperature, and that a pseudogap develops with underdoping.

Three-dimensional topological insulators are materials that are nonmagnetic insulators in the bulk but exhibit metallic surface states. Yoshimi et al, now identify a signature of such two-dimensional states, the quantum Hall effect, in bismuth-based chalcogenide topological insulators.

In this phase 2 basket trial, patients with heavily pretreated HER2-mutated metastatic breast cancer received the small-molecule HER2 inhibitor tucatinib and anti-HER2 trastuzumab, leading to encouraging clinical response rates.

A topologically protected state can exist at the interface between a topological insulator and an ordinary insulator. Here, the authors use photoemission spectroscopy to show that the topological Dirac-cone state migrates from the surface of the topological insulator TlBiSe₂to an attached bismuth film.

In spin hydrodynamic generation originating from the coupling of mechanical rotation in a fluid and electron spin, fluid vorticity can be converted into an electric voltage via a spin current. Here, the authors demonstrate experimentally that the energy conversion in a laminar flow regime is strongly enhanced over the turbulent regime.

Genome-wide association studies (GWAS) have improved our understanding of the genetic basis of lung adenocarcinoma but known susceptibility variants explain only a small fraction of the familial risk. Here, the authors perform a two-stage GWAS and report 12 novel genetic loci associated with lung adenocarcinoma in East Asians.

The dissipation of heat towards cooler regions of a thermodynamic system is a ubiquitous phenomenon. It is now shown that collective excitations known as spin waves can be used to control the flow of heat in a ferrimagnet consisting of Y₃Fe₅O₁₂.

Controlling the motion of atoms in solids with light allows for a deeper understanding of their fundamental properties, yet most studies only deal with one spatial dimension. Katsuki et al.extend this approach to two-dimensional control and use it to visualize atomic motion in bismuth.

Genome-wide association and fine-mapping analyses in ancestrally diverse populations implicate candidate causal genes and mechanisms underlying type 2 diabetes. Trans-ancestry genetic risk scores enhance transferability across populations.

The evidence of topological origin for the recently observed anomalous Hall effect remains elusive. Here, the authors report that the resonance of the optical Hall conductivity resulted from topological electronic structure gives rise to the large intrinsic anomalous Hall effect in the magnetic Weyl semimetal Co₃Sn₂S₂.

Relative contributions to Earth’s total heat flux from the radioactive decay of isotopes versus primordial heat are debated. Measurements of geoneutrino particles emitted during radioactive decay in the Earth’s interior indicate that radiogenic isotopes contribute only about half of the total heat flux.

Using more than 100 independent iPSC lines derived from patients with Alzheimer’s disease, the authors discovered loci associated with the neuronal production of amyloid β and confirmed their influence using RNA interference.
