Background: Placenta accreta spectrum (PAS) is one of the most dangerous pregnancy-related conditions. This study aims to conduct a systematic review of current research on the ultrasound scoring systems used in PAS patients with a comprehensive summarization of researches and comparison of prenatal ultrasound scoring in evaluating postpartum outcomes.
Methods: This systematic review was conducted and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Building on the algorithmic equivalence between finite population replicator dynamics and particle filtering based approximation of Bayesian inference, we design a computational model to demonstrate the emergence of Darwinian evolution over representational units when collectives of units are selected to infer statistics of high-dimensional combinatorial environments. The non-Darwinian starting point is two units undergoing a few cycles of noisy, selection-dependent information transmission, corresponding to a serial (one comparison per cycle), non-cumulative process without heredity. Selection for accurate Bayesian inference at the collective level induces an adaptive path to the emergence of Darwinian evolution within the collectives, capable of maintaining and iteratively improving upon complex combinatorial information.

Introduction: Tobacco consumption is a leading cause of mortality globally. Eighty percent of these deaths occur in low- and middle-income countries (LMICs). Despite this, there is a large treatment gap due to both demand and supply-side barriers.

Most members of the genus Orthonairovirus, represented by Crimean-Congo hemorrhagic fever virus and Nairobi sheep disease virus, are tick-borne, and some have become a public health concern in recent years. Here, we report the isolation and genetic and biological characterization of a new orthonairovirus, designated as "Iwanai Valley virus" (IWVV), from Ixodes ovatus ticks in Hokkaido, Japan. The amino acid sequence of the viral nucleoprotein (NP) was found to be 34-45% identical to those of known orthonairoviruses.

Article Synopsis
- Jumbo phages are large viruses with genomes over 200 kbp, and little is known about their life cycle and unique reproductive genes.
- Researchers assembled 668 high-quality jumbo phage genomes from 955 samples of various animal species and identified the largest known phage genome at 716 kbp, revealing they can synthesize NAD and contain numerous NAD-consuming enzymes.
- The study highlights the widespread presence of NAD-jumbo phages in different ecosystems, emphasizing the need for further research on their ecological roles and survival strategies.
