Understanding and controlling the skyrmion lattice (SkL) phase facilitates its versatile applications. Here the direct observation of a SkL phase with large topological Hall effect in centrosymmetric Gd3Ru4Al12 is reported, which is stabilized by thermal fluctuations and magnetic field without Dzyaloshinskii-Moriya interactions.
Activation of APC/C depends on transient interactions with an activator subunit. Here, the authors show that cellular polyanions trigger APC/C-activator dissociation and that high-affinity substrates block this effect, suggesting that substrate availability controls APC/C-activator binding.
Selective hydrogenolysis of biomass glycerol to propanediol is a promising route for the production of high-value chemicals but remains a challenge. Here, the authors find a PtCu single atom alloy catalyst exhibits remarkably boosted performance with a turnover frequency value of 2.6 × 103 molglycerol·molPtCu–SAA−1·h−1.
Single strand breaks represent the most common form of DNA damage yet no methods to map them in a genome-wide fashion at single nucleotide resolution exist. Here the authors develop such a method and apply to uncover patterns of single-strand DNA “breakome” in different biological conditions.
Producing ethanol from carbon dioxide, water, and renewable electricity offers a route to sustainable energy. Here, the authors enhance electrocatalytic activity for carbon dioxide reduction by tuning adsorbed hydrogen in a class of copper catalysts with oxide- and hydroxide-modified surfaces.
Triple-negative breast cancer (TNBC) is an aggressive subtype lacking effective targeted therapies. Here, the authors show that RNF208, an estrogen-induced ubiquitin ligase, promotes the degradation of Vimentin, thereby suppressing lung metastasis of TNBC, and may serve as a biomarker for the disease.
Integrating independent large-scale pharmacogenomic screens can enable unprecedented characterization of genetic vulnerabilities in cancers. Here, the authors show that the two largest independent CRISPR-Cas9 gene-dependency screens are concordant, paving the way for joint analysis of the data sets.
The increasingly prevalent view of magmatic systems as mush-dominated challenges the common assumption that melt inclusions record the pre-eruptive storage and processing of the melts they were erupted with. Here, the authors show that melt inclusions from Kīlauea Volcano, Hawai'i exhibit extreme compositional diversity, consistent with the accumulation of inclusion-bearing crystals in magmatic mush zones for >170 years before their eventual eruption in unrelated carrier melts.
Stroke risk is influenced by genetic and lifestyle factors and previously a genomic risk score (GRS) for stroke was proposed, albeit with limited predictive power. Here, Abraham et al. develop a metaGRS that is composed of several stroke-related GRSs and demonstrate improved predictive power compared with individual GRS or classic risk factors.
The repressive states of peroxisome proliferator-activated receptor γ (PPARγ) are ill-defined, despite nuclear receptors being a major drug target. Here authors demonstrate multiple structurally distinct repressive states, providing a structural rationale for ligand bias in a nuclear receptor.
Although it is known that microglia respond to injury and systemic disease in the brain, it is unclear if they modulate blood–brain barrier (BBB) integrity, which is critical for regulating neuroinflammatory responses. Here authors demonstrate that microglia respond to inflammation by migrating towards and accumulating around cerebral vessels, where they initially maintain BBB integrity via expression of the tight-junction protein Claudin-5 before switching, during sustained inflammation, to phagocytically remove astrocytic end-feet resulting in impaired BBB function
The use of machine learning for identifying small molecules through their retention time’s predictions has been challenging so far. Here the authors combine a large database of liquid chromatography retention time with a deep learning approach to enable accurate metabolites’s identification.
Pavlovian and instrumentally driven actions often conflict when determining the best outcome. Here, the authors present an arbitration theory supported by human behavioral data where Pavlovian predictors drive action selection in an uncontrollable environment, while more flexible instrumental prediction dominates under conditions of high controllability.
Although the hedgehog (HH) pathway is known to be deregulated in medulloblastoma, inhibitors of the pathway have shown disappointing clinical benefit. Using single-cell sequencing in a mouse model of the disease, the authors show that the response to the HH pathway inhibitor vismodegib is cell-type specific.
Newly acquired plasmids are frequently lost due to fitness costs. Here, Zhang et al. show that the evolution of satellite plasmids with gene deletions can reduce fitness costs by driving down the copy number of full plasmids and thus favor maintenance of the full plasmid and its novel accessory genes.
Why transposable elements (TEs) accumulate in polyploids and the evolutionary implications remain unclear. Here, the authors show that following whole genome duplication, relaxed purifying selection is the main driver of TE over-accumulation, which provides variants for rapid local adaptation.
Heart failure is a major health issue worldwide. Here, Egerstedt et al. perform proteomic profiling of human plasma at different stages of heart failure, providing a comprehensive analysis of changes in the plasma proteome during disease progression.
Mechanical forces are sensed by cells and can alter plasma membrane properties, but biochemical changes underlying this are not clear. Here the authors show tension is sensed by c-Abl and FBP17, which couples changes in mechanical tension to remodelling of the plasma membrane and actin cytoskeleton.
Here, Heaney et al. show that La Niña conditions are associated with higher than average incidence of childhood diarrheal disease in Botswana in the early rainy season. This finding could help to predict childhood diarrhea outbreaks in southern Africa.
Acetylation of p53 is critical for its transcriptional activity and its tumour suppressive function. Here, the authors show that PBRM1 is a reader protein for p53′s C-terminal domain acetylation on lysine 382 through its bromodomain 4 and that mutations in this domain leads to compromised tumour suppressive function and renal tumour growth.
