【#Tech24H】NASA’s Curiosity rover has, for the first time, detected a nitrogen-bearing molecule structurally similar to a DNA precursor deep within the ancient lakebed of Gale Crater on Mars, an unprecedented chemical signature on the Martian surface. The rover also confirmed the presence of benzothiophene, a “bulky” double-ring sulfur-containing molecule that typically arrives via meteorite hitchhikers. [ By Zhang Liyan | Tang Ruohan ]
