Origin of life in a digital microcosm

, 2017
While all organisms on Earth descend from a common ancestor, there is no consensus on whether the origin of this ancestral self-replicator was a one-off event or whether it was only the final survivor of multiple origins.

The Efficacy and Safety of Bevacizumab/Irinotecan/Temozolomide (BIT) for Relapsed/Refractory Neuroblastoma: The UK Children's Cancer and Leukaemia Group Experience

Pediatric Blood &Cancer, Volume 73, Issue 5, May 2026.
ABSTRACT Background Patients with high‐risk neuroblastoma who either are refractory to induction chemotherapy or relapse following multi‐modal treatment have a dismal prognosis. Based on data from the BEACON trial, since 2021 the UK national guidelines recommend bevacizumab, irinotecan, and temozolomide (BIT) for patients with relapsed/refractory ...

Design and Development of Molecular Beacon-Based Real-Time PCR Assays to Identify Clostridioides difficile Types of Main Evolutionary Clades

Microbiology Research
C. difficile infection (CDI) has an important impact on both human and animal health. The rapid detection and monitoring of C. difficile PCR-ribotypes (RTs) cause of CDI is critical to control and prevent this infection.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, Volume 600, Issue 9, Page 1373-1385, May 2026.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Decoding the Cardiac Immune Microenvironment and Fibroblast Crosstalk in Radiotherapy Combined with Immunotherapy‐Induced Cardiac Fibrosis Based on Single‐Cell Transcriptomic Analysis

Advanced Science, Volume 13, Issue 25, 4 May 2026.
This study highlights that radioimmunotherapy drives crosstalk between fibroblasts and immune cells (especially macrophages) in the cardiac microenvironment, with IL‐6 as the key mediator, and tocilizumab alleviates cardiac fibrosis by targeting this interplay.
