Current thyroid ultrasounds rely heavily on the experience and skills of the sonographer and of the radiologist, and the process is physically and cognitively exhausting. Here, the authors show a fully autonomous robotic ultrasound system, which is able to scan thyroid regions without human assistance and identify malignant nodules.

Melting and squeezing pure metals between two sapphires covered in molybdenum disulfide produces diverse two-dimensional metals at the ångström thickness limit.

Gut inflammation and bone loss have previously been linked. Here, the authors show colon-targeted engineered postbiotics can protect the gut and reduce systemic inflammation, which rebalances inflammation disturbed osteoblast-osteoclast levels restoring bone homeostasis.

In the CNS, glutamatergic neurons directly control functional hyperemia via synaptic-like transmission onto arteriolar smooth muscle cells. Inhibiting this process reduces brain atrophy following cerebral ischemia.

Controlling the crystallization of perovskites is not trivial. Here Wang et al. develop a close-space annealing to improve the structural and optoelectronic quality of perovskite films with different chemical compositions, leading to over 25% efficiency in all-perovskite tandem solar cells.

An in situ phase-separation method at microscale level creates stretchable superelastic porous nanocomposite conductors, reduces conductive filler usage and enables strain-resilient wireless wearable and implantable bioelectronics.

A self-assembled monolayer of (4-(7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid is integrated in wide-bandgap perovskite solar cells, which enables a high power conversion efficiency and low open-circuit voltage deficiency, as well as efficient centimetre-scale all-perovskite tandem solar cells.

Via Raman and infrared spectroscopy measurements, X. Zan et al. find that rhombohedral ABC trilayer graphene has stronger electron/infrared-phonon coupling than Bernal ABA trilayer graphene.

As cancer is increasingly considered a metabolic disorder, it is postulated that serum metabolite profiling can be a viable approach for detecting the presence of cancer. Here, the authors report a machine learning model using mass spectrometry-based liquid biopsy data for pan-cancer screening and classification.

Effective reprogramming of chronic wound healing remains challenging due to the limited drug delivery efficacy hindered by physiological barriers, as well as the inappropriate dosing timing in distinct healing stages. Here, the authors report a core-shell structured microneedle array patch with programmed functions which dynamically modulates the wound immune microenvironment according to the varied healing phases

Using genetically tailored protein-based nanoprobes and taking advantage of image-segmentation-based machine learning, a high-throughput assessment of vascular permeability of individual blood vessels in 32 different tumours is quantified. These insights are valuable in developing personalized anticancer nanomedicine therapeutics and strategies modulating vascular permeability to treat tumours.

Tumour repopulating cells (TRC) are stem-like cells that can escape immune-mediated killing. Here, the authors show IFN-γ results in either dormancy or apoptosis of TRC depending on the activation of the IDO1 metabolic pathway, and that combining IFN-γ with IDO1 inhibitors results in enhanced tumour regression.

Many biological tissues exhibit directionally dependent properties. Here, authors develop tissue-like elastomer composites with programmed mechanical and electrical anisotropy and discuss potential applications in bioelectronics and humanoid artificial muscles.

Li et al. demonstrate mitochondrial fission in macrophages as key for phagocytosis induced by therapeutic antibodies. They identify overexpression of GFPT2 as an inhibitor of the process and phase transition of the phagocytic machinery as its regulator.

The Clivias are a series of small, monomeric fluorescent RNAs that emit with a large Stokes shift in the orange–red. They enable multiplexed RNA imaging in live cells and BRET-based detection of protein–RNA interactions in mice.

IL-2 is a classic T cell growth factor. Huang and colleagues demonstrate, however, that chronic IL-2 stimulation leads to a new exhaustion pathway that impairs antitumor immune responses.

Lu et al. demonstrate that allergens induce the formation of eosinophil extracellular traps, which activate pulmonary neuroendocrine cells to secrete neuropeptides and neurotransmitters as well as amplify allergic immune responses.

Electrochromic smart windows can be low-power routes to control building temperatures. This Review describes the working modes, assembly protocols and implementation of these windows.
