Here the authors report a strategy to alter these properties by modifying the protein coatings with biofunctional molecules, and generate long-wavelength fluorophores for in vivo imaging.

Sexual dimorphism exists in a number of physiological processes, including energy homeostasis. Here, the authors show that pro-opiomelanocortin neurons in female mice fire more rapidly than males, and that deletion of the transcription TAp63 leads to a reduced neuronal firing rate and a male-like susceptibility to diet-induced obesity.

Black carbon (BC) is distinguished into two parts (char vs soot) in emission sources and inventories, char is revealed as the core component of China’s historical emissions and the optimal target for future BC reductions.

Skeletal muscle’s metabolic status has an impact on health and the prognosis of chronic diseases. Here the authors unveil an atlas of open chromatin regions in skeletal muscles using single-nucleus techniques on juvenile male mice, highlight regulatory dynamics between normal and denervated states, and pinpoint ELK4 as a pivotal factor in muscle atrophy.

A new donkey reference genome and comparisons with wild asses yields insights into the evolutionary history of donkey domestication and identifies a genetic variant that results in the non-Dun coat colours of domestic donkeys.

COVID-19 pandemic is a global health risk, but our understanding on the induced durable immunity remains scarce. Here the authors assess antibody responses in 869 convalescent COVID-19 patients to find that specific antibody titers reduce with time, and the RBD-IgG positive rate exceed 70% at 12 month post diagnosis, with male and older patients showing stronger responses.

Suppressing grain boundaries and defects in perovskite solar cells remains a quest to address the efficiency and stability issues. Here, the authors use methylamine gas for assisting the growth of uniaxial-oriented perovskite thin films with millimeter-sized grains.

Actuators provide robot locomotion and manipulation, but most are limited by their number of motion types and coupled motions. Here, Zhang et. al. present an origami actuation module based on a modified Kresling pattern with pneumatically-driven pouches, thus enabling seven motion modes in one module.

A liquid drop hovers over the surface when placed on a hot surface that is hotter than the Leidenfrost point because a vapor film will form beneath the drop. Here authors report how to manipulate drops by cutting the Leidenfrost film using chemically heterogeneous surfaces.

Flexible perovskite solar cells suffer huge efficiency loss upon area scale-up due to brittleness of ITO and poor perovskite film quality. Here Meng et al. solve this by inserting a conductive and glued polymer layer between ITO and perovskite layers and obtain efficiency of 17% for 30 cm² devices.

Neurons expressing pro-opiomelanocortin (Pomc) regulate food intake and body weight. Here the authors show that Steroid Receptor Coactivator-1 (SRC-1) regulates the function of Pomc expressing neurons, and that rare heterozygous variants found in obese individuals lead to loss of SRC-1 function.

3D photonic crystals (PCs) attract attention due to their unique optical properties but printing of colloidal particles is limited by lack of control over the assembly. Here, the authors demonstrate a continuous digital light processing 3D printing strategy using hydrogen bond assisted colloidal inks for fabricating well-assembled 3D PC structures.

A truncating variant of 17β-hydroxysteroid dehydrogenase-13 (17β-HSD13), a lipid droplet -associated protein, associates with lower risk of chronic liver disease. Here the authors identify a phosphorylation site in 17β-HSD13 which promotes lipolysis, and report that a knock-in mouse with a 17β-HSD13 mutant defective for phosphorylation is more susceptible to nonalcoholic steatohepatitis.

Intragastrically delivered polymeric micelles releasing butyrate along the intestinal tract restore barrier-protective responses in mouse models of peanut allergy and colitis.

Satellite drops formed on droplet impact hinder applications from inkjet printing to drop energy harvest. Here, authors reveal that patterned-wettability surfaces can break the symmetry of droplet impacts and suppress the Plateau–Rayleigh instability, preventing satellite drop generation and improving the hydropower harvest.

Neuronal signaling has an important role in the regulation of energy expenditure and body weight, however, the underlying mechanisms are incompletely understood. Here, the authors report a AgRP-MC4R-serotonin expressing neuronal circuit that regulate energy expenditure without affecting feeding.

Digital light processing and stereolithography have low wet material utilization efficiency. Here the authors propose a one-droplet 3D printing strategy to fabricate 3D structures from a single resin droplet.

Chronic obstructive pulmonary disease is a leading cause of morbidity and mortality. Here, the authors analyse whole genome sequence data and find new loci associated with lung function and COPD.

Molecular diagnostics for tuberculosis have focused on predicting drug susceptibilities in a binary manner (i.e., strains are either susceptible or resistant). Here, CRyPTIC Consortium researchers use whole genome sequencing and a quantitative assay to identify associations between genomic mutations and minimum inhibitory concentrations in over 15,000 Mycobacterium tuberculosis clinical isolates.

Conventional human pluripotent stem cells (hPSCs) fail to contribute to interspecies chimaeras when injected into mouse blastocysts. Here the authors show that forced expression of BMI1 overcomes apoptosis of hPSCs in blastocysts of mouse, rabbit and pig allowing them to contribute to chimaeras.
