Recent science articles from The Washington Post:
"NASA, Pentagon award contract to build nuclear-powered rocket engine": Lockheed Martin wins a contract to develop a nuclear-powered rocket engine, aiming for a 2027 test flight. The article mentions that NASA is keen on such an engine for Mars missions, and notes that
"Nuclear thermal power uses a fission-based nuclear reactor to heat hydrogen to an extremely high temperature and then shoot the gas through an engine nozzle to create thrust. Lockheed Martin said that for safety reasons, the reactor would not be turned on until the spacecraft has reached a safe orbit."
"Scientists woke up a 46,000-year-old roundworm from Siberian permafrost": "A female microscopic roundworm that spent the last 46,000 years in suspended animation deep in the Siberian permafrost was revived and started having babies in a laboratory dish." "The frozen soil the nematode was embedded in came from an ancient gopher hole, excavated from about 130 feet below the surface." "Researchers thaw the soil, taking care to not warm it too quickly to avoid cooking the nematodes. The worms then start wriggling around, eating bacteria in a lab dish and reproducing."
