Most NIR radiation absorbers used in multi jet fusion 3D printing have an intrinsic dark color which prevents printing parts with variable colors. Here, the authors design an activating fusing agent containing a strong NIR absorbing dye that turns colorless after harvesting irradiation energy during the 3D printing process and provide a bright colored part when working with other color agents.
Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena but little is known about how organisms regulate crystallization to produce optically useful morphologies. Here, the authors demonstrate that pre-assembled, fibrillar sheets in developing scallop eyes template nucleation and direct the growth and orientation of plate-like guanine crystals showing a striking resemblance to melanosome morphogenesis.
Physical distancing measures introduced to control the spread of COVID-19 had socio-economic trade-offs that may have particularly impacted vulnerable population groups. Here, the authors perform a scoping review and summarise the impacts on different vulnerable groups described in 265 studies.
Covalent organic frameworks (COFs) are an emerging type of crystalline and porous photocatalysts for hydrogen evolution. Here, the authors report a β-ketoamine COF by systematically engineering N-sites, architecture, and morphology for improved water splitting activity.
The Planckian metal is a special case of a strange metal, in which the linear-in-temperature scattering rate reaches a universal limit. Here the authors study this state in a heavy-fermion superconductor in magnetic field and propose a microscopic mechanical based on quantum criticality of the Kondo hybridization.
Morphogenetic shape changes are regulated by mechanical properties of interacting tissues, but other factors remain less studied. By exploring how homeotic genes regulate morphogenesis, Villedieu et al. uncover how the interplay between genetic patterning and initial tissue geometry drives morphogenesis during development.
Glycerol flux across the plasma membrane is critical to metabolism and linked to disease. Here, authors present the cryo-EM structure of the glycerol channel AQP7 composed of two adhering tetramers and displaying well-defined densities in the central pore.
The paper presents a method that allows scaling machine learning interatomic potentials to extremely large systems, while at the same time retaining the remarkable accuracy and learning efficiency of deep equivariant models. This is obtained with an E(3)- equivariant neural network architecture that combines the high accuracy of equivariant neural networks with the scalability of local methods.
Sustainable recycle of spent Li ion batteries is an effective strategy to alleviate environmental concerns and support resource conservation. Here, authors report the direct regeneration of LiFePO4 cathode using multifunctional organic lithium salts, leading to high environmental and economic benefits.
Covalent organic frameworks are more and more used in the design of stimuli responsive materials. Here, the authors expand the application range of COFs by demonstrating a sweat induced colour change for detection of fingerprints using a sweat responsive COF.
Plant biosynthetic enzymes rapidly evolve to catalyze specialized reactions. Here, the authors present the crystal structure and mechanism of COSY, the enzyme involved in coumarin biosynthesis of the BAHD-acyltransferase family that catalyzes an intramolecular acyl transfer reaction through a proton exchange mechanism.
Controlling molecular motion is challenging. Here, the authors report the effect of counter cations on the rotational barriers of hydroquinone rings in a molecular rotor based on anionic pillar[5]arenes.
This paper finds that the winter sea-ice over the Barents-Kara Seas has exhibited strengthened interannual variations in recent decades likely due to increased amplitudes of the El Niño-Southern Oscillation in a warming climate.
Much recent work has focused on the kagome metals AV3Sb5 (A = K, Rb, and Cs), but studies of the monolayer form are only just beginning. Here, the authors theoretically study monolayer kagome metals, and predict modified van Hove singularities that lead to charge-density-wave doublets and d-wave superconductivity.
Clathrate hydrates are topological duals of Frank-Kasper phases. Here, the authors employ MD simulations to provide an alternative way to explore the intrinsic structural relationships of H-bonded networks of clathrate hydrates and other unrelated ordered materials.
Myelodysplastic syndromes are characterised by clonal haematopoiesis, with the affected cells often harbouring mutations in the TET2 gene, an important regulator of DNA methylation state. Here authors show that the same mutations are also found in NK cells, perturbing their DNA methylation pattern and cytolytic function.
The anti-freezing property of electrolyte is crucial for aqueous batteries under extreme conditions. Here authors explore the relationship between tetrahedral entropy and the freezing behavior of aqueous electrolyte, and further develop anti-freezing electrolyte for aqueous zinc ion batteries.
SARS-CoV-2 variants of concern continue to emerge, reducing vaccine efficacy and limiting therapeutic options. Here, Chen and colleagues describe the identification and design of shark nanobodies with pansarbecovirus activity.
Alternative polyadenylation (APA) contributes to the post-transcriptional regulation of most human genes, yet the effects of APA are largely overlooked by conventional transcriptome-wide association studies (TWAS). Here, the authors conduct an APA-TWAS for 11 brain disorders, identifying hundreds of APA-linked disease susceptibility genes.
The authors report a systematic analyses of blood biomarkers for metabolism against the whole spectrum of diseases in 100,000 individuals and reveals a prominent role of numerous metabolic biomarkers as risk markers beyond heart disease and diabetes.
