Here, the authors present a cryo-EM validation method for the local analysis of the map-to-model fit and introduce FSC-Q as a quality measure. FSC-Q provides a quantitative estimation of how much of the model is supported by the signal content of the map.
Early life trauma has been associated with multiple sclerosis, but the causal link is unclear. Here the authors show in mice that early life trauma can result in IFN-β-resistant EAE as a result of β-adrenergic desensitization in immune cells and that a β1 adrenergic receptor agonist can reverse this susceptibility.
Global energy transformation requires quantifying the "price of energy" and studying its evolution. Here the authors present a predictive framework that calculates the average US price of energy, estimating future energy demands for up to four years with excellent accuracy, designing and optimizing energy and monetary policies.
RIG-I is a cytosolic antiviral nucleic acid sensor that signals via MAVS to produce type 1 interferons. Here the authors show that hepatits B virus can repress this pathway by activating glycolysis and lactate production, enabling accumulated lactate to bind MAVS and prevent its mitochondrial localization.
The genetic determinants of sex-specific differences in obesity are still incompletely understood. Here, the authors demonstrate that adipocyte specific loss of Trim28 in committed adipocytes leads to sex specific differences in the development of obesity, and that this phenotype is associated with altered metabolic flexibility and lipid metabolism.
Nanopore reads have been advantageous for de novo genome assembly; however these reads have high error rates. Here, the authors develop an error correction and de novo assembly tool, NECAT, which produces efficient, high quality assemblies of nanopore reads.
Loss of small GTPase RAC1 suppresses intestinal tumorigenesis caused by APC loss, but impacts normal intestinal homeostasis. Here, the authors provide an alternative method of reducing RAC1 activity by the combined targeting of three RAC-GEFs and show that this approach delays intestinal tumorigenesis without the detrimental effects on normal intestinal architecture.
Recent observations of missing odd Shapiro steps have been interpreted in the context of topological superconductivity. Here, the authors observe missing odd Shapiro steps in topologically trivial Josephson junctions due to high transparency of the junctions, calling for caution in relationship to topological superconductivity.
Centrosome clustering is a promising therapeutic target in cancer but how it is regulated remains unclear. Here, the authors show that in response to DNA damage, ATM/ATR stabilize the centrosome clustering regulator KIFC1 leading to increased clustering efficiency and tumour recurrence.
SARS-CoV-2 induces mild infection in ferret model. Here, Ryan et al. characterise optimal infection dosage inducing upper respiratory tract (UTR) viral shedding, progression time of viral shedding, and pathology in ferrets and finally provide evidence for protection after re-challenge.
Mitochondrial oxidation-induced cell death is an important physiological process activated by cancer therapeutics, but its investigation is challenging. Here, the authors report a multifunctional iridium(III) photosensitiser, Ir-OA, able to induce mitochondrial oxidative stress and monitor the corresponding changes in mitochondrial properties.
The SOX2 pioneer transcription factor performs critical roles in pluripotency and self-renewal of embryonic stem cells. Here the authors show that SOX2’s two nuclear localization signal sequences form a contiguous binding interface on the nuclear import receptor importin-α3, and provide a structural basis for the preference of SOX2 binding to IMPα3.
COVID-19 diagnosis is commonly performed by PCR testing, however, serologic methods are more accurate and versatile for monitoring disease burden and epidemiology. Here the authors report a protein microarray with antigens from SARS-CoV-2, SARS-CoV, MERS-CoV as well as common human respiratory viruses.
Age is one of the strongest risk factors for severe illness from COVID-19. By integrating human lung transcriptomes with experimental data on SARS-CoV-2, the authors pinpoint specific age-associated factors that could contribute to the heightened severity of COVID-19 in older populations.
Influencer networks include a small set of highly-connected nodes and can reach synchrony only via strong node interaction. Tönjes et al. show that introducing an optimal amount of noise enhances synchronization of such networks, which may be relevant for neuroscience or opinion dynamics applications.
Computational catalysis would strongly benefit from general descriptors applicable for predicting adsorption energetics. Here the authors propose a machine-learning approach for adsorption energy predictions based on learning the relevant descriptors in a surface atom's density of states as part of the training.
Citrullination of arginine is crucial for several physiological processes. Here the authors report the site-specific incorporation of citrulline into proteins in mammalian cells using an engineered tRNA synthetase/tRNA pair and a photocaged-citrulline.
ZEB2 transcription factor is increased in a subset of cardiomyocytes during stress to induce cardioprotective effects after injury. Here the authors show that therapeutic delivery of ZEB2 prevents cardiac dysfunction after ischemic damage and promotes the activation of pro-angiogenic signals.
Current histone microarrays cannot be used to directly study the transient interactions of histone deacetylases (HDACs). Here, the authors show that hydroxamic acid-modified microarrays can capture HDACs, provide insights into their substrate specificity, and serve to develop peptide inhibitors.
Some algae produce compounds called alkenones that can reconstruct sea surface temperature through geological time, but in high latitudes unknown species complicate use of this proxy. Here the authors find a lineage of sea ice algae that produces alkenones and can be used as a paleo-sensor for sea ice abundance.
