Researchers at UC Berkeley have uncovered a microbe, *Methanosarcina acetivorans*, that challenges a fundamental genetic principle by interpreting a "stop" codon as an instruction to insert an unusual amino acid and continue protein synthesis. This discovery reveals a surprising flexibility in the genetic code, overturning long-held beliefs about its rigidity and opening new avenues for understanding genetic disorders.
Scientists have discovered "bizarre, plume-like swirls" deep beneath Greenland's ice sheet, a thermal convection phenomenon likened to a "pot of boiling pasta." This groundbreaking observation reveals ice is softer and more sensitive to stress than previously thought, significantly impacting predictions for global sea-level rise and the stability of the massive ice sheet.
Joint Israeli-U.S. airstrikes have reportedly killed five students at an Iranian girls' school, with U.S. President Trump confirming "major combat operations" and urging the Iranian public to revolt.
