Drop impact on a liquid surface leads to the formation of vortex rings, but this process is still poorly understood due to the lack of effective experimental characterization. Here, Leeet al. visualize the process using ultrafast X-ray phase-contrast imaging and follow the dynamics of vortex rings.

There has been impressive progress in the development of perovskite solar cells in recent years, but the best performing systems tend to be fabricated on glass surfaces. Here, the authors present a cell built on a polymer substrate, allowing flexibility whilst maintaining high efficiency.

Control of liquid-based materials is important for developing materials based on these, but topological flexibility is limited. Here, the authors report a method for digital fabrication of slippery objects with solid-liquid composite interfaces and geometric design freedom.

Light trapped in the active polymeric layer limits the total efficiency of polymer light-emitting diodes. Here, Lee et al.get round this bottleneck by enhancing light extraction in waveguide optical modes via ripple-shaped nanostructures that spontaneously form on ZnO electrode surfaces.

Ni-rich cathodes in all-solid-state batteries experience capacity fading due to surface degradation, particle isolation and detachment at the cathode–electrolyte interface. This study quantifies these degradation factors, showing that detachment increases with Ni content and emphasizing the need for strategies to address these challenges.

Water has remarkable dynamic properties; a transition from a fragile to a strong liquid has been proposed to explain how they change on cooling. Experiments now show evidence for such a transition in bulk supercooled water at around 233 K.

An improved device design for perovskite-based photovoltaic cells enables a certified power conversion efficiency of 25.2 per cent, translating to 80.5 per cent of the thermodynamic limit for its bandgap, which approaches those achieved by silicon solar cells.

Metal-free neural electrodes enable simultaneous electrophysiological recording and optical imaging but often face challenges in impedance reduction. Here, Kim et al. develop a fully metal-free PEDOT:PSS neural interface with ultra-low impedance, high transparency, and compatibility with two-photon imaging.

Here, the authors present cryoEM structures of AftB, a key mycobacterial enzyme that adds terminal arabinose residues to the cell wall. In concert with functional assays and MD simulations, mechanistic insights are presented.

Cultured neuron networks provide insight into network structure and function, but the ability to control network topology is a challenge. Here the authors develop a nanorod-mediated thermoplasmonics platform that enables the formation of new connections, the abolishment of existing connections, and the modulation of network activity during cultivation.

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.

Thermal lepton pairs are ideal probes for the temperature of quark-gluon plasma. Here, the STAR Collaboration uses thermal electron-positron pair production to measure quark-gluon plasma average temperature at different stages of the evolution.

The Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) in South Korea has now entered operation with a timing jitter of just 20 fs.

Integrating self-healing capabilities into skin-like stretchable transistors presents a persistent challenge. Here, by using a supramolecular polymer matrix, the authors develop autonomous self-healing transistors and skin-like logic circuits.

Small-conductance Ca²⁺ -activated K⁺ (K_Ca2.1-K_Ca2.3) channels modulate neuronal and cardiac excitability. Here, authors report cryo-EM structures of the K_Ca2.2 channel, providing a basis for understanding the small unitary conductance and pharmacology of K_Ca2.x channels.

Yoon Shin Cho and colleagues report a genome-wide association study for nine metabolic traits in east Asians. They identify ten new loci that are associated with these traits.

How the Drosophila lymph gland hemocytes develop and are regulated at a single-cell level is unclear. Here, the authors use single-cell RNA sequencing to show heterogeneity of developing hemocytes in the lymph gland and how they react to wasp infestation, and compare hemocytes from two independent origins.

The Somatic Mosaicism across Human Tissues Network aims to create a reference catalogue of somatic mosaicism across different tissues and cells within individuals.

Here the authors merge spatiotemporal modulation LED device, precise control and efficient polarization emission and programmable patterning/positioning using 3D printing demonstrating encryption in visible light communication (VLC) enabled by polarization state modulation.

Comprehensive analyses of 178 lung squamous cell carcinomas by The Cancer Genome Atlas project show that the tumour type is characterized by complex genomic alterations, with statistically recurrent mutations in 11 genes, including TP53 in nearly all samples; a potential therapeutic target is identified in most of the samples studied.

Persistent antigen stimulation can cause exhaustion and unresponsiveness of CD8 cells, impairing the immune response. Here the authors show that increasing the number of CD8 cells, decreasing the antigen load or providing CD4 help can overcome the exhaustion and establish a memory response.

Anthraquinones are aromatic polyketides and have been used for treating various diseases, but the biosynthetic pathway is unclear. Here, the authors assemble the genome of an anthraquinone-producing medicinal plant Senna tora and show the evidences that CHS-like genes may be involved in anthraquinone biosynthesis.

The collective-flow-assisted nuclear shape-imaging method images the nuclear global shape by colliding them at ultrarelativistic speeds and analysing the collective response of outgoing debris.

Microvilli can participate in adhesion or migration of T cells, but whether they are involved in function regulation is unclear. Here the authors show that T cell microvilli form budding vesicles containing T cell signalling components for deposition onto antigen presenting cells (APC) and modulation of APC functions.

An antimatter hypernucleus formed by an anti-lambda hadron, an antiproton and two antineutrons was observed through its two-body decay after production in ultrarelativistic heavy-ion collisions.

Prevalence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) higher in men than premenopausal women. Here the authors report that formyl peptide receptor 2 (FPR2) levels are regulated by estrogen, and that FPR2 contributes to NAFLD resistance in female mice.

The STAR collaboration reports a measurement of the mass difference and binding energy of the hypertriton and its antiparticle. This work constrains the hyperon–nucleon interaction and allows us to test the CPT theorem in a nucleus with strangeness.
