Quote of the day by Robert A. Heinlein: “Everything is theoretically impossible, until…” – why the word “impossible” has such a poor track record |

Robert A. Heinlein (Image: Wikipedia) History is full of confident predictions that turned out to be spectacularly wrong. Flight was impossible, right up until two bicycle makers got a machine off the ground. Reaching the moon was a fantasy, right up until a man stepped onto it. The science fiction writer Robert A. Heinlein captured…

Arctic alarm: Earth’s frozen carbon stores in the Arctic may stop absorbing CO2 and start releasing it by the 2050s |

The Arctic is warming far faster than the rest of the planet, and a new study published in Science Advances suggests that this warming could transform one of Earth’s biggest natural carbon stores sooner than scientists once thought. Researchers say northern soils above 30°N, including vast areas of permafrost, may switch from absorbing carbon to…

A concrete-free wind turbine could change how renewable energy is deployed worldwide |

For decades, wind power has relied on a familiar formula: enormous towers, vast concrete foundations and specialised heavy-lift equipment capable of transporting and assembling components that can weigh hundreds of tonnes. While effective, these requirements have limited where wind turbines can be deployed and increased both costs and environmental impacts. Now, a new generation of…

Soviet spacecraft built to land on Venus in 1972 spent 53 years orbiting Earth and finally returned without burning up |

A Soviet spacecraft designed to land on Venus in 1972 finally completed its journey more than half a century later, though not in the way its builders intended. Kosmos 482, part of the Soviet Union’s ambitious Venera programme, was supposed to explore the Solar System’s hottest planet. Instead, a rocket malfunction left the spacecraft trapped…

NASA prepares Nancy Grace Roman Space Telescope for Florida launch from Kennedy Space Centre ahead of August launch |

The journey is almost over for NASA’s next major space observatory, though its most important work has yet to begin. After years of design, assembly and testing, the Nancy Grace Roman Space Telescope has arrived at the agency’s Kennedy Space Centre in Florida, where teams will spend the coming weeks preparing the spacecraft for launch….

Trees have a hidden climate superpower: They keep absorbing carbon long after growth stops |

For decades, forests have occupied a central place in discussions about climate change. Trees remove carbon dioxide from the atmosphere, convert it into organic matter and store part of that carbon in their trunks, branches and roots. The process seems straightforward enough. More photosynthesis should mean more growth, and more growth should mean more carbon…
