A nanofluidic intracellular delivery (NanoFLUID) patch provides a versatile, biocompatible and efficient method for the targeted delivery of payloads to internal organs for therapeutic purposes and for biomolecular investigations.

Designing efficient and stable acidic oxygen evolution catalysts is challenging. Here, the authors construct high-density grain boundaries in V-doped RuO₂ to tune its electronic structure and boost stability, addressing the activity/stability trade-off in proton exchange membrane water electrolyzers.

Developing electronic skins for sensing the spatial ___location of objects beyond two-dimensional space is difficult. The authors present a flexible, lightweight, and transparent electronic skin for non-contact accurate 3D motion sensing. This achieves micron-level precision, reducing complexity and power consumption.

Ancient DNA, stable isotopes and other archaeological methods establish that humans were living at extremely high elevation on the Tibetan Plateau 4,400 years ago, maintaining sedentary lifestyles that combined fishing, hunting and crop exchange.

The SARS-CoV-2 pandemic highlighted our need for methods that allow rapid viral surveillance. Here, authors report a wireless, battery-free and wearable self-diagnosis platform that can continuously capture viral particles, diagnose infection status and evaluate symptom severity via breath and blow.

The haptic interface is an essential part of human–machine interfaces where tactile information is delivered between human and machine. Yao et al. develop a soft, ultrathin, miniaturized and wireless electrotactile system that allows virtual tactile information to be reproduced over the hand.

Incorporation of a ‘liquid diode’ into a wearable electronic platform enhances comfort and stability by shunting away sweat as it accumulates.

A haptic interface that uses thermal, mechanical and electrotactile modes of stimulation to target different receptors in the skin can provide users with diverse haptic sensations, reproducing the tactile information of fine roughness, macro roughness, slipperiness, force and temperature.

Continuous monitoring of arterial blood pressure is limited by bulky connecting systems and poor interfacial contact. Here, Li et al. report a wearable thin, soft, miniaturized system that integrates sensing, active pressure adaptation, and signal processing for improved performance and accuracy.

Breast cancer cells are known to metastasize to the bone but why the cells should migrate and metastasize to this particular organ is not clearly understood. Here, the authors show that EZH2 activates an integrin B1 and FAK signaling pathway in breast cancer cells, which activates TGFB signaling to drive metastasis in the bone.

Efficient and stable electrocatalysts for acidic oxygen evolution are essential for proton exchange membrane electrolyzers. Here, the authors report Ru–O–Ir atomic interfaces that enable bridging oxygen-mediated deprotonation pathways, overcoming the activity/stability trade-off in acidic oxygen evolution.

No method exists for real-time evaluation of the status of spinal implants. Here, the authors developed a bio-adhesive metal detector array (BioMDA) that provides a wearable, non-invasive solution for positional analyses of osseous implants within the spine.

Existing ingestible electronics suffer from poor tissue contact, short dwell time, and limited battery life. Here, the authors report an ingestible, battery- free, and tissue-adhering robotic interface for non-invasive and chronic electrostimulation of the gut.

Increasing the metal loading of single-atom catalysts (SACs) typically results in aggregation, which can have a detrimental effect on catalytic performance. Now, a nitrogen-doping-assisted atomization approach is reported that transforms metal-sulfide nanoparticles into ultrahigh-density metal–nitrogen–carbon SACs.

An electronic skin that connects rigid inorganic electronic components with a multilayered stretchy liquid metal fibre mat using a hybrid liquid metal solder can offer high integration density while remaining soft, permeable and biocompatible.

Perovskite zinc sulphide phosphors in perovskite-based alternating-current electroluminescent devices are employed as skin-wearable devices with high stretchability, monochromaticity and power efficiency.

Electromagnetic devices involving a vibratory actuator and a soft strain-sensing sheet can dynamically measure the Young’s modulus of skin and of other soft biological tissues at depths of millimetres.

In atherosclerotic plaques, transformation of macrophages into foam cells is a key step in initiating the inflammatory response. Here Fan et al. show that casein kinase 2-interacting protein-1 (CKIP-1) limits foam cell formation and atherosclerosis by preventing expression of the scavenger receptor LOX-1 through REGγ-mediated degradation of Oct-1.

Prabhakar et al. demonstrate in rats with mitomycin C-caused pulmonary veno-occlusive disease activation of protein kinase R (PKR) and the integrated stress response (ISR), leading to the depletion of VE-cadherin and RAD51 from endothelial junctions, endothelial barrier disruption and vascular remodeling. Inhibiting the PKR–ISR axis protects against mitomycin C-induced endothelial damage.

Virtual reality technologies need olfactory systems to improve human perception, but their bulky formats limit their practicality. Here, Liu et. al. report flexible and miniaturized odor generators with tunable odor concentration in close user proximity for immersive virtual reality applications.

The formation of secondary organic aerosol in Chinese megacities is dominated by the condensation of anthropogenic organic vapours, according to measurements across three urbanized regions.

Health-oriented emissions reduction in China focusing on the iron and steel industry can reduce costs by 1.56 billion dollars while lowering the population-weighted toxic potency-adjusted exposure risk.

Analyses of atmospheric nitrogen chemistry in Beijing’s air pollution during the COVID-19 lockdown suggest an increasing role of nighttime nitrogen chemistry in haze formation above the city.
