A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Post-translational modifications play crucial roles in viral infections, yet many potential modifications remain unexplored in orthoflavivirus biology. Here we demonstrate that the UFMylation system, a post-translational modification system that catalyzes the transfer of UFM1 onto proteins, promotes infection by multiple orthoflaviviruses including dengue virus, Zika virus, West Nile virus, and yellow fever virus. We found that depletion of the UFMylation E3 ligase complex proteins UFL1 and UFBP1, as well as other UFMylation machinery components (UBA5, UFC1, and UFM1), significantly reduces infectious virion production for orthoflaviviruses but not the hepacivirus, hepatitis C.

Aims: To explore physician-reported knowledge, use, and perceptions of genetic testing for advanced ovarian cancer management.

Materials & Methods: Gynecology/oncology specialists ( = 390) in the US, Europe, Canada, Japan, and Australia completed an online survey spanning March 2021 to April 2022.

Results: Physician-reported breast cancer gene mutation (BRCAm) testing rates increased over the 2 years before the survey; most patients underwent testing in the preceding 6 months.

Article Synopsis
  • The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
  • A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
  • The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.

Ecosystems globally have reached critical tipping points because of climate change, urbanization, unsustainable resource consumption, and pollution. In response, international agreements have set targets for conserving 30% of global ecosystems and restoring 30% of degraded lands and waters by 2030 (30×30). In 2021, the United States set a target to jointly conserve and restore 30% of US lands and waters by 2030, with a specific goal to restore coastal ecosystems, namely wetlands, seagrasses, coral and oyster reefs, and mangrove and kelp forests, to increase resilience to climate change.
