New gene regulation mechanism discovered

Scientists at Cold Spring Harbor Laboratory identified a messenger RNA molecule that switches from non-protein coding status to protein coding status in response to cellular stress. This 'cut and run' mechanism likely controls the expression of many genes, providing a rapid response to viral infection or other stresses.

Breakup of glaciers raising sea level concern

Researchers warn that the breakdown of major ice sheets in Greenland and Antarctica could significantly speed up sea level rise, potentially doubling current projections. The study suggests that these mechanisms should be carefully considered in future climate models to ensure accurate sea level rise predictions.
