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.

Owing to the presence of strongly bound excitons and degenerate valleys, monolayer transition metal dichalcogenides show promise for valleytronic applications. Here, the authors embed monolayer WSe₂ in a monolithic dielectric cavity, and observe room-temperature valley coherence of valley-polaritons.

Microcavity exciton-polaritons in atomically thin semiconductors are a promising platform for valley manipulation. Here, the authors show valley-selective control of polariton energies in monolayer WS2 using the optical Stark effect, thereby extending coherent valley manipulation to a hybrid light-matter regime

The authors timestamp the development of amyloid plaques in a mouse model of Alzheimer’s disease in order to examine how plaque age affects the surrounding brain tissue. This includes a growing loss of nearby synapses, an increase in toxicity, and an increase in structural aggregation.

Impurity spins in solids are controllable multilevel quantum systems that can be harnessed for implementing quantum memories. In this work, the authors investigate the coupling strength between spins in a ruby crystal and a quantized electromagnetic mode using electron spin resonance technique.

Conservation laws are a key ingredient in the non-equilibrium dynamics of quantum many-body systems. Here, the authors develop generalised quantum fluctuation relations in order to identify the presence of conserved quantities relevant for a generalised Gibbs ensemble.

Using an artificial three-level lambda system realized in a superconducting transmon qubit in a microwave cavity one can observe coherent population trapping, electromagnetically induced transparency and superluminal pulse propagation.

The evolution of a quantum state undergoing radiative decay depends on how the emission is detected. Here, the authors demonstrate how continuous field detection, as opposed to the more common detection of energy quanta, allows control of the back-action on the emitter’s state.

Methods to identify bacterial cell surface adaptations are limited. The authors combine phage display with high-throughput DNA sequencing to create a highly-multiplexed technology for surveying bacterial cell surfaces.

An analysis of data from 522 population-based studies encompassing 82 global regions and spanning more than a century (1920–2024) shows spatiotemporal transitions across epidemiologic stages 1 to 3 of inflammatory bowel disease, and models stage 4 progression.

Cellular glycosylation is complex and heterogeneous, which is challenging to reproduce synthetically. Here, the authors report on enzymatic remodelling of multivalent glycosylated bacteriophages to produce genetically encoded library of N-glycans which can be used to measure glycan-protein interactions with lectins on the surface of live cells and organs.

Microwaves are usually used to interact with superconducting qubits, but optical photons can be processed at room temperature. The electro-optical transceiver presented here allows all-optical readout of a qubit without affecting its performance.

Alterations in the tumour suppressor genes STK11 and/or KEAP1 can identify patients with advanced non-small-cell lung cancer who are likely to benefit from combinations of PD-(L)1 and CTLA4 immune checkpoint inhibitors added to chemotherapy.

Phylogeographic analyses can provide broad descriptions of the spread of pathogens between populations, but are limited by incomplete sampling. Here, the authors develop an inference framework that reconstructs sequential transmission events and use it to characterise dynamics of dengue in Thailand.

A short isoform of the SARS-CoV-2 host receptor ACE2, expressed in human nasal and bronchial respiratory epithelia, is upregulated in response to interferon treatment and rhinovirus infection, but not SARS-CoV-2 infection.

A 'circuit' quantum electrodynamics system where a superconducting qubit acts as an atom-like two-energy level system and is embedded in a microwave transmission circuit (acting as the optical cavity) is studied. In this system, it is demonstrated that the creation of pure quantum states, known as Fock states, which give specific numbers of energy quanta, in this case photons. Fock states with up to six photons are prepared and analysed.

Sequential drinks of crosslinker and polymer solutions form a tough hydrogel in the stomach, enabling delivery of drugs and biologics in this harsh chemical environment.

A biosensor comprising bacteria engineered to respond to transient inflammatory signals has been packaged with electronic readout and transmission circuits in a small device that could be swallowed to monitor gastrointestinal health.

The Parker Solar Probe mission has reached the inner heliosphere of the Sun and made measurements of energetic particle events in the near-Sun radiation environment.

FGF19 increase in post-bariatric hypoglycaemia is mediated by bile acid dysregulation, and can be countered by inhibiting bile acid transport.

Networks of atom–cavity systems necessarily require that single atoms sit near dielectric interfaces. Real-time monitoring of caesium atoms just 100 nm from the surface of a micro-toroid resonator now demonstrates that the Casimir effect plays an important role in these systems.

A systematic investigation of the spin relaxation in nitrogen vacancy centres in diamonds, induced by phononic vacuum modes at low temperature, reveals an upper limit of eight hours.

Alternative superconducting qubit designs with improved performance are attracting attention. Here the authors introduce an inductively shunted transmon qubit that offers protection against flux noise and measures quantum tunneling between fluxon states that are shown to be stable for hours.

The CMS Collaboration reports the study of three simultaneous hard interactions between quarks and gluons in proton–proton collisions. This manifests through the concurrent production of three J/ψ mesons, which consist of a charm-quark–antiquark pair.

A novel variant annotation metric that quantifies the level of expression of genetic variants across tissues is validated in the Genome Aggregation Database (gnomAD) and is shown to improve rare variant interpretation.

Fine-mapping of causal variants and integration of epigenetic and chromatin conformation data identify likely target genes for 150 breast cancer risk regions.

The CMS Collaboration reports evidence for off-shell Higgs boson contributions in the production of Z boson pairs, and measures the width of the Higgs boson, which is inversely related to its lifetime.

The most up-to-date combination of results on the properties of the Higgs boson is reported, which indicate that its properties are consistent with the standard model predictions, within the precision achieved to date.
