Researchers have discovered a new way ribonucleic acid (RNA) impacts fear-related learning and memory. Researchers demonstrated that a noncoding RNA known as Gas5 coordinates the trafficking and clustering of RNA molecules inside the long processes of neurons, and orchestrating neuronal excitability in real time that contributes to learning and memory. This study builds on earlier findings this year which identified a separate population of learning-related RNAs that accumulate near the synapse -- the junction between neurons that allow them to communicate. In that paper, published in the Journal of Neuroscience, they uncovered several new synapse-specific RNA that harbour a specific chemical tag called N6-methyladenosine (m6A).

Scientists provide new evidence to motivate rapid fossil fuel phaseout. The science team determined exposure to ambient air pollution and its health impacts using an updated atmospheric composition model, a newly developed relative risk model and recent satellite-based fine particle data. They estimated all-cause and disease-specific mortality and attributed them to emission categories. They show that phasing out fossil fuels is a remarkably effective health-improving and life-saving intervention. About 5 million excess deaths per year globally could potentially be avoided.
