In this randomized, controlled integrated phase 1/2/3a/3b clinical trial, the authors show that the self-amplifying mRNA COVID-19 vaccine ARCT-154 shows good immunogenicity and is safe and efficient against COVID-19 (57% against any COVID-19, and 95% against severe COVID-19).
Phytoplankton blooms provoke bacterioplankton blooms, from which bacterial biomass (necromass) is released via zooplankton grazing and viral lysis. Here, Beidler et al. show that the bacterial biomass, including alpha-glucan polysaccharides generated from the consumption of algal organic matter, is reused by microbes in vitro and during a diatom-dominated bloom.
Lead toxification in society is a public health crisis. The exposure to lead poisoning gives rise to a multitude of health issues. In this work, a chip-scale photonic platform that enables the highly quantitative detection of lead is demonstrated.
Accurate monitoring of methane emissions is essential to understand its contribution to global warming. The authors here employ multi-spectral satellite data to create a methane detection tool with global coverage and high temporal and spatial resolution.
Providing a suitable multi-electrode array (MEA) for free-floating neural organoids is a great challenge. Here, authors present a mesh soft stretchable MEA for recording neural signals in human hippocampal organoids derived from induced pluripotent stem cells.
This study uses a customized metasurface to unveil a distinct parity Hall effect in degenerate optical vectorial modes. This work realizes the advances in meta-devices and showcases new possibilities for manipulating optical fields based on parity.
The main challenge for anti-HSV therapy is to target latent virus in ganglionic neurons. Here, the authors report a well-tolerated anti-HSV gene editing approach against HSV which targets latent HSV genomes and leads to reductions of ganglionic viral loads, and viral shedding upon reactivation in mouse models.
Here, the authors demonstrate a wafer-scale, low-temperature process using atomic layer deposition, for the synthesis of uniform, conformal amorphous boron nitride (aBN) thin films. They further fabricate aBN-encapsulated monolayer MoS2 field-effect transistors.
Oxidative damage to intracellular membrane proteins is critical to cells. Here, the authors use a water-oxidizing photocatalyst, generating ∙OH even under hypoxia, to show that membrane-specific protein oxidation triggers pyroptosis via non-canonical inflammasomes.
Microfibrillar-associated protein 4 (MFAP4) is involved in fibrotic and cardiovascular diseases. Wozny et al. reveal structural aspects mediating MFAP4 octamer formation critical for its interaction with elastogenic proteins and cells.
Here the authors have developed a superconducting microwave frequency comb that is fully integrated, easy to manufacture, and operates with ultra-low power consumption, and could significantly advance microwave photonics and quantum processor integration.
Utilizing “Chemistry at a point”, Ni is exsolved from a perovskite lattice under deposited Pt nanoparticles. This yields even smaller Ni Pt alloy nanoparticles on a perovskite nanofiber structure, exhibiting high catalytic activity.
Crystals with mechanical responses are of interest, but often only one or two dynamic motions can be achieved with one crystal. Here, the authors report a combination of dynamic movements in naturally twisted optical waveguiding microcrystals.
Here, the authors utilise NMR and cryo-EM to characterise the binding of an allosteric modulator to μ-opioid receptor (MOR), revealing modulator binding can potentiate receptor activation by altering the conformational dynamics in the core region of MOR.
Methylation of CHMP2B regulates abscission timing by modulating ESCRT-III dynamics during cytokinesis. This methylation also plays a role in HIV-1 budding, highlighting the broader significance of ESCRT-III methylation.
In recent years a growing demand for drug design approaches that incorporate a higher number of sp3-hybridized carbons fuelled the development of innovative cross-coupling strategies to reliably introduce aliphatic fragments. Here, the authors present a powerful approach for the light-mediated B-alkyl Suzuki−Miyaura crosscoupling between alkyl boranes and aryl bromides.
The details of how the protein folding and degradation systems collaborate to combat potentially toxic non-native proteins are unknown. Here the authors perform systematic studies of missense and nonsense variants of the cytosolic aspartoacylase, ASPA, where loss-of-function variants are linked to Canavan disease.
In this work, the authors apply polymer models to reconstruct the 3D structure of the genome during SARS-CoV-2 infection and examine how the virus impacts key mechanisms of chromatin organization.
Here, the authors characterize selenium and sulphur incorporated FeMo cofactors of the catalytic MoFe protein component from Azotobacter vinelandii under turnover conditions using EPR.
The term ‘holobiont’ refers to a multicellular organism and its microbial symbionts. Whether and how symbionts react to host injury and how cellular responses are integrated across species remain unexplored. Here, the authors report a deeply conserved animal regeneration regulatory program that links molecular networks across species in an animal-algal holobiont.
