Traders of financial options bet that firms’ stock prices will be affected by forecasts of seasonal climate produced by the U.S. National Oceanic and Atmospheric Administration. Firms are exposed throughout the economy, and traders spend more to hedge the news from more skillful forecasts
The authors use femtosecond K-edge X-ray absorption spectroscopy to follow nuclear motion in a manganese-based tri-nuclear single-molecule magnet, and resolve changes in bond lengths on the order of hundreds of ångströms and on sub-picosecond timescales.
Esophageal adenocarcinoma is characterised by frequent amplifications in oncogenes. Here, the authors use short- and long-read sequencing approaches to analyze primary tumor samples and tumour-derived organoids and to investigate the mechanisms underlying complex amplifications.
The Sargasso Sea is a natural laboratory for understanding future conditions of warmer oceans and associated nutrient limitation. Here, the authors combined short- and long-read sequencing to survey Sargasso Sea viral communities.
The relationship between the structural configurations of M-N-C electrocatalysts and their performances in neutral environments has been insufficiently investigated. Here the authors demonstrate that an ultralow metal-loaded Co-N-C electrocatalyst, featuring the asymmetric Co-C/N/O configuration, exhibit exceptional efficiency in electrochemically producing hydrogen peroxide under neutral conditions.
Adaptive laboratory evolution provides a real-time record of physiological change. In bacteria adapted to glucose over 40 000 generations, this study finds an apparent increase in enzyme efficiency consistent with increased substrate saturation due to loss of a flux sensing mechanism early in adaptation.
Anaplastic thyroid cancer (ATC) is a particularly aggressive cancer type with limited effective therapeutic options. Here, the authors identify the SUMO E3 ligase PIAS2 as a potential therapeutic target in ATC and mechanistically investigate its role in mitotic spindle and centrosome assembly.
HIMU-type seamounts may be subducted elsewhere beneath the Mariana arc, but obvious HIMU-type components appear only in the initial stages of arc rifting due to the low melting degree and being consumed during the process of back-arc spreading.
How diurnal primates develop exploration-navigation strategy and how the physiology of primate hippocampus is shaped in navigation are not fully understood. Here authors show that marmosets adapted their navigation strategies to their diurnal ecological niche. Notably, marmoset hippocampal neurons are specialized for encoding combinations of view, head direction and place, and that theta oscillations are triggered by rapid head-gaze movements.
Single-cell sequencing has enabled detailed analyses of the tumour microenvironment (TME). Here, the authors perform an integrative analysis of the TME using single-cell and spatial transcriptomics data from over a thousand tumours across thirty cancer types, identifying interferon-enriched community states predictive of immunotherapeutic responses.
NH4+-derived pathways, rather than NO3--derived pathway, are the dominant hyporheic N2O sources in lower-order streams. These findings provide insights into better estimation of N2O emissions in global models of riverine ecosystems and emphasize the importance of managing ammonium.
There is a lack of atomic level insight on the role of defects on carbon nanotubes' growth. Here, authors present a machine learning force field to drive near-microsecond simulations the entire growth process of this material, unveiling mechanisms of defect formation and healing.
Children typically exhibit weaker memory than adults. Here, the authors report a developmental reversal-like phenomenon that children show better memory for attended but outdated information, suggesting underdeveloped memory selection in children.
How cells adapt to glucose starvation is still elusive. Here, Levy et al. show that the mTOR substrate 4EBP1 protects human, mouse, and yeast cells from glucose starvation and is exploited by cancer cells to promote tumorigenesis.
Efforts to apply targeted protein degradation for antibiotic development are limited by our understanding of prokaryotic protein degradation. Here, the authors establish a chemical-genetic platform and predictive model to determine the degradation potential of essential mycobacterial proteins.
The impact of obesity on cancer remains insufficiently explored. Here the authors show that in mouse models, dysfunctional adipocytes exhibit low levels of BECN1 which induce YAP/TAZ activity to promote breast and colorectal tumor progression.
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.
