A triangular-lattice organic conductor κ-(BEDT-TTF)₄Hg_2.89 Br₈ is a promising doped spin liquid candidate which also exhibits superconductivity. Here the authors report thermoelectric measurements under pressure and find a quantum critical phase that could be correlated to BEC-like superconductivity.

Charge-frustration-induced melting of charge order is identified on a conducting organic triangular lattice, with a possible role of quantum effects.

Several organic materials exhibit spin liquid phases, which are predicted to host exotic spinon excitations that emerge from non-local quantum effects. Here, the authors identify a quasi-continuous phase transition in κ-(ET)₂Cu₂(CN)₃ that may be associated with the presence of spinons.

It is expected that introducing charge carriers into an exotic quantum spin liquid state may lead to an unconventional metal but there are no clear realizations of a metallic spin liquid. Here, the authors present a spin liquid candidate that also shows evidence of strange metal behavior.

Mayumi Tamari and colleagues report a genome-wide association study for adult asthma in a Japanese population. They identify three new asthma susceptibility loci.

Emmanuel Mignot and colleagues report that variants in the T-cell receptor alpha (TRA@) locus are strongly associated with narcolepsy. This is the first documented involvement of the TCR locus in human disease and will shed light on how HLA-TCR interactions contribute to organ-specific autoimmune targeting.

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.

Saloner et al. used large-scale cerebrospinal fluid proteomics to uncover molecular signatures in frontotemporal dementia, revealing RNA splicing and synaptic protein candidate markers for genetic and sporadic disease progression.

Photoinduced phase transition is a central issue in the field of non-equilibrium quantum physics. Here, the authors demonstrate that a terahertz electric-field pulse changes a Mott insulator of an organic molecular compound to a macroscopically polarized charge-order state.

The Mott transition between an insulator and a metal can be tuned by applying pressure, which affects the electronic correlations. In an insulating organic salt, NMR studies reveal that the spin fluctuations are suppressed whereas the conductance is enhanced by the same critical exponent as pressure drives the insulator into a bad metal.

The Mott transition is investigated in three different organic insulators with triangular lattices and evidence of quantum criticality in an intermediate temperature regime is uncovered.

Irradiation with a strong terahertz electric-field pulse is found to induce a Mott transition in an organic molecular compound. The metallization is attributed to an impulsive dielectric breakdown.

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.

Strong electronic correlations are expected to generate novel behaviour in materials possessing exotic massless electrons with a relativistic nature. Here, the authors demonstrate the reshaping of tilted Dirac cones and ferrimagnetism associated with Coulombic interactions in a layered organic compound.

Pulmonary arterial hypertension is a progressive fatal disease characterized by pathological pulmonary artery remodeling. Here the authors show that the dysregulation of the activin A-bone morphogenetic protein receptor type 2 link in the endothelium is involved in the progression of pulmonary hypertension.

The ATLAS Collaboration reports a measurement of the ratio of the decay rates of W bosons to τ leptons and muons, in agreement with universal lepton couplings as postulated in the standard model of particle physics.

The ATLAS experiment at the Large Hadron Collider reports a search for charged-lepton-flavour violation in decays of Z bosons into a τ lepton and an electron or muon of opposite charge.

Geometrically frustrated spin-systems do not order magnetically even at absolute zero, forming instead a spin liquid or a glassy state. An organic conductor in which the charges, rather than spins, are frustrated now shows a similar absence of long-range order, resulting in a charge-cluster glass at low temperature.

Quantum electrodynamics predicts a rare process in which light is scattered by light. The ATLAS Collaboration reports signs of this elusive effect in the collisions of ultra-relativistic lead ions.

Ten years after the discovery of the Higgs boson, the ATLAS  experiment at CERN probes its kinematic properties with a significantly larger dataset from 2015–2018 and provides further insights on its interaction with other known particles.

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.

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.

Emmanuel Mignot and colleagues report genome-wide association analyses identifying a new susceptibility locus for narcolepsy. They identify associated variants in the 3′ untranslated region of P2RY11, a purinergic receptor that modulates immune cell viability.

Transperineal prostate biopsy is re-emerging after decades of being an underused alternative to transrectal biopsy guided by transrectal ultrasonography (TRUS). The authors describe the evolution of both the prostate biopsy techniques, focusing on the clinical implications of the transperineal approach and the potential future directions for prostate biopsy.

Kaoru Ito, Yoichiro Kamatani, Toshihiro Tanaka and colleagues report a genome-wide association study for atrial fibrillation in the Japanese population. They identify six new loci, five of which are not associated with atrial fibrillation in individuals of European ancestry, suggesting that they may be specific to the Japanese population.
