Tiny RNA Molecule QT45 Achieves Self-Replication, Shedding Light on Life's Origins
Researchers at MRC Laboratory of Molecular Biology discovered QT45, a small RNA polymerase ribozyme that copies itself and its complementary strand, supporting the RNA world hypothesis for life's beginnings. This breakthrough, published in Science, was achieved through laboratory evolution of random RNA sequences. It challenges prior theories by showing feasible spontaneous emergence due to its tiny size.
Indian Scientists Decode Triggers for Explosive Solar Eruptions Threatening Power Grids
Scientists at ARIES identified weak background magnetic fields and rapid buildup of Absolute Net Current Helicity (ANCH) as key factors enabling coronal mass ejections (CMEs) to escape the Sun. Using MHD simulations based on the breakout model, the study explains higher CME rates in weaker solar cycles like Cycle 24. These findings aid space weather forecasting to protect infrastructure.
