Science news today spans both planetary instability and technological ambition. A powerful 7.3 to 7.4 earthquake off southern Mexico near the Guatemala border triggered tsunami warnings across parts of Central America, prompting evacuations and alerts before the threat was later eased, with no immediate reports of major casualties. In a very different kind of energy story, India unveiled its first domestically built hydrogen-powered passenger train in Haryana, a symbolic step toward cutting emissions across one of the world’s largest rail networks. And in Texas, SpaceX’s latest Starship test was halted just 13 seconds before liftoff when engine ignition failed, a dramatic reminder that even routine-looking countdowns can end in setbacks. Together, the day’s developments capture science and engineering at their extremes: managing nature’s sudden force while pushing cleaner transport and heavier-lift spaceflight forward through trial and error.
