  • PARP inhibitors (PARPi) have been approved for the treatment of metastatic triple-negative breast cancer (BC), however resistance and recurrence are often observed. Here, in preclinical models of BRCA1/2 wild type and homologous recombination competent BC, the authors show that C5aR1-positive tumor associated macrophages are associated with PARPi-resistance, suggesting targeting C5aR1 as a therapeutic option.

  • Intermittency is the behavior of extreme fluctuations observed in the flow of a fluid that is often associated with high Reynolds numbers. Here, the authors report intermittency in elastic turbulence at the low Reynolds number and high Deborah number limit.

  • The structure of the Golgi and the localization of glycosylation enzymes remain largely elusive. Here, the authors use super-resolution microscopy to show that the Golgi is composed of small dynamic units which have rapidly moving zones of glycosylation enzymes.

  • The neural mechanisms setting the lower limit of conscious visual perception in humans is not fully understood. Here the authors show by correlating human vision experiments and non-human primate retina recordings that primates rely on the retinal ON pathway in perception of the dimmest light increments, and that nonlinear thresholding in this pathway eliminates single photons and neural noise thereby allowing perception of minute differences in light intensity.

  • Zero to ultralow-field NMR provides chemical information in the absence of a high magnetic field but it is difficult to measure molecules with quadrupolar nuclei due to their fast relaxation. This study examines zero-field J-spectra from isotopologues of ammonium cations, with quadrupolar nuclei, revealing the presence of a primary isotope effect of −58 mHz.

  • In this study, the authors employ metagenomics to explore the impact of environmental pollution on the human gut microbiome using samples from a cohort living in a very polluted area in Southern Italy, showing that pollutants degradation genes are more abundant in subjects with higher blood levels of those specific xenobiotics.

  • Bacterial-fungal interactions can stimulate the production of specialised microbial metabolites. Here, Richter et al. use co-culture experimental evolution to show that the presence of a fungus selects for increased surfactin production in the bacterium Bacillus subtilis, which inhibits fungal growth and facilitates the competitive success of the bacterium.

  • Urothelial cancer is a challenging disease and an emerging field for targeted therapies. Here, the authors optimize clinical proteomics to provide proteome-level data on tumor specificity and identify robust prognostic subtypes with predictive information for repurposed drug candidates.

  • Zhao P.J. and his colleagues uncover spatial directionality of urban mobility by using new metrics of anisotropy and centripetality. They find monocentric cities have longer commutes with city expansion, while polycentric cities maintain consistent commuting patterns.

  • Species-rich communities tend to be less vulnerable to species invasions, but whether this is maintained under environmental stress is unclear. This meta-analysis shows that the positive effect of biodiversity on resistance to invasion in grassland plant communities is reduced by drought but increased by warming and multiple global change factors.

  • The researchers showcase a silicon-photonics-based analog approach for large-scale image processing that can be deployed for high-speed image compression and de-noising using an auto-encoder framework with minimal power consumption.
