Here, Sun et al. report the pressure-induced dome shape of a magnetic phase superceding the nematic order in FeSe, suggesting competing nature between magnetism and superconductivity.

The understanding of the reemergence of pressure induced superconductivity in alkali-metal intercalated FeSe is hampered by sample complexities. Here, Sun et al. report the electronic properties of (Li_1–xFe _x )OHFe_1–ySe single crystal not only in the reemerged superconducting state but also in the normal state.

Here, the authors report pressure-induced superconductivity with concomitant enhancement of antiferromagnetic transition in layered EuTe₂. The superconductivity is distinctly characterized by the high upper critical fields exceeding the Pauli limit among binary tellurides, a prerequisite of the coexistence of ferromagnetism with superconductivity.

Despite much recent effort, the highest reported T_c of the infinite-layer nickelates remains lower than 15 K. Here, the authors apply pressure to Pr_0.82Sr_0.18NiO₂ thin films and observe a monotonic increase of T_c to 31 K at 12.1 GPa, an increase that does not level off with increasing pressure.

Understanding the physics of transition metal oxides that move beyond the commonly studied 3d orbital state is important for future studies. Taking the (CaCu₃)B₄O₁₂ family as an example, Meyers et al.examine the electronic and magnetic structure as the B-site changes from Co to Rh and Ir.

John Chambers and colleagues identify common variants at four loci associated with serum creatinine levels, a marker of kidney function. Their findings provide insight into the pathways underlying susceptibility to chronic kidney disease.

In anaphase, any unresolved DNA entanglements between the segregating sister chromatids can give rise to chromatin bridges. Here, the authors present an in vitro single-molecule assay that mimics chromatin under tension, to show that PICH is a tension- and ATP-dependent nucleosome remodeler.

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.

Chemical mapping of a single molecule by optical means down to subnanometre resolution is achieved by spectrally matching the resonance of a nanocavity plasmon to the vibronic transitions of the molecules being studied, using tip-enhanced Raman scattering.

Measurements of the inelastic cross section of anti-³He allow the estimation of the transparency of the Milky Way to the propagation of these light antinuclei produced in either cosmic-ray collisions or annihilation of dark-matter particles.

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.

Lasing in X-ray free-electron lasers is typically achieved by self-amplification of spontaneous emission, which is known to have non-ideal temporal coherence and suffer from beam fluctuations. Here researchers report lasing based on echo-enabled harmonic generation at the Shanghai Deep Ultraviolet free-electron laser facility.

Nanocavity plasmons are exploited as a coherent optical source with tunable energy and to actively control the radiative channels of molecules. Intense resonance enhancement of both excitation and emission, in an effect called resonant hot-electroluminescence, is demonstrated for porphyrin molecules confined inside a nanocavity.

Atomically thin boron nitride remains undercharacterized in terms of their mechanical properties. Here authors test high-quality mono- and few-layer BN and show it to be one of the strongest electrically insulating materials and dramatically better in interlayer integrity than graphene under indentation.

Biological fate of nanomaterials in organisms is an important topic, however, limitations of analytical techniques has hampered understanding. Here, the authors report on a study into the fate of model, gold nanoparticles in an aquatic food chain using an analytical workflow and range of analytical methods.

Lipid concentration in the serum is one of the most important risk factors for coronary artery disease and can be targeted for therapeutic intervention. A genome-wide association study in >100,000 individuals of European ancestry now finds 95 significantly associated loci that also affect lipid traits in non-European populations. Among associated loci are those involved in cholesterol metabolism, known targets of cholesterol-lowering drugs and those that contribute to normal variation in lipid traits and to extreme lipid phenotypes.

Accumulation of lipid-laden macrophages in the arterial wall is a critical step in atherosclerosis. Here, the authors show that downregulation of Zeb1 in macrophages promotes lipid accumulation and atherosclerotic plaque formation while its restoration with macrophage-targeted nanoparticles reverses these effects.

It is challenging to quantitatively diagnose the lithium-ion distribution in batteries. Here, the authors use laser-assisted atom probe tomography to probe the nanoscale compositional fluctuations of lithium ions in two popular lithium-ion battery cathodes before and after electrochemical cycling.

Different adjacent molecules adsorbed on a surface can be distinguished by their Raman modes using a plasmon-enhanced Raman scattering technique with a spatial resolution below 1 nm.

Luminescence induced by highly localized excitations that are produced by electrons tunnelling from the tip of a scanning tunnelling microscope is used to map the spatial distribution of the excitonic coupling in well-defined arrangements of a few zinc-phthalocyanine molecules and the dependence of this spatial distribution on the relative orientation and phase of the transition dipoles of the individual molecules.

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

The physics of thermal diffusion — mass diffusion driven by a temperature gradient — is poorly understood. One obstacle has been that the Soret coefficient (S_T, which describes the steady-state result of thermal diffusion) is sensitive to many factors. It is now shown that the difference in S_T between isotopes of diffusing elements that are network modifiers is independent of composition and temperature. The findings suggest a theoretical approach for describing thermal diffusion in silicate melts and other complex solutions.

Reduced glomerular filtration rate (eGFR) is a hallmark of chronic kidney disease. Here, Pattaro et al. conduct a meta-analysis to discover several new loci associated with variation in eGFR and find that genes associated with eGFR loci often encode proteins potentially related to kidney development.

A combination of single-molecule techniques shows that the repair proteins XRCC4 and XLF form heteromeric mobile sleeve-like complexes that can bridge and hold together fragments of broken DNA.
