The fossilized skull of a 455-million-year-old fish reveals an anatomy that’s completely new to the study of vertebrates, bridging a knowledge gap of 100 million years. Insights gained from studying the Ordovician jawless fish, Eriptychius americanus, suggest the early development of the vertebrate brain’s protective dome was more complex than scientists thought. “This fills a

Engineers working with the European Space Agency have developed a new thruster design smaller than the tip of your finger. Despite its small size, this mini-thruster designed for CubeSats appears to be highly efficient without the use of toxic chemicals. Called the Iridium Catalysed Electrolysis CubeSat Thruster (ICE-Cube Thruster), it allows CubeSats to maneuver without

NASA’s Parker Solar Probe flew right through a massive solar eruption and caught the whole thing on camera. It’s the first up-close footage ever captured of a solar explosion like this. The video, released by scientists at Johns Hopkins Applied Physics Laboratory, features an especially powerful coronal mass ejection that took place last year. CMEs

An experiment that took place on Mars has shown that it’s feasible to extract breathable oxygen from the thin Martian atmosphere. From its little home in the belly of NASA’s Perseverance rover, the briefcase-sized Mars Oxygen In-Situ Resource Utilization (ISRU) Experiment (MOXIE) has been repeatedly breaking apart molecules in Mars air to generate a small,

Former political leaders and heads of international organisations called Thursday for national moratoriums on deploying technologies to slow global warming by dimming the impact of the Sun. The Climate Overshoot Commission said research and experiments into so-called solar radiation modification (SRM) should move forward, but only under international supervision and in jurisdictions with strong environmental

Human activity and appetites have weakened Earth’s resilience, pushing it far beyond the “safe operating space” that keeps the world liveable for most species, including our own, a landmark study said Wednesday. ​Six of nine planetary boundaries – climate change, deforestation, biodiversity loss, synthetic chemicals including plastics, freshwater depletion, and nitrogen use – are already
