A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the […]

Author: Sevrine Sailley, Senior Scientist, Marine Ecosystem Modelling, Plymouth Marine Laboratory Climate change is reshaping fish habitats. Some fish are winners, others are losing out. Fish already face plenty of pressure from overfishing and pollution. Climate change is adding more: warmer waters and shifting food supplies cause what’s known as a predator-prey mismatch. This means […]

The Dead Sea is a confluence of extraordinary conditions: the lowest point on Earth’s land surface, with one of the world’s highest salinities. The high concentration of salt gives it a correspondingly high density, and the water body’s status as the deepest hypersaline lake gives rise to interesting and often temperature-related phenomena below the water’s […]

Authors: Davide Foffa, Research Fellow in Palaeobiology, University of Birmingham; Alfio Alessandro Chiarenza, Royal Society Newton International Fellow in Palaeontology, UCL, and Emma Dunne, Assistant Professor in Paleobiology, Friedrich-Alexander-Universität Erlangen-Nürnberg Ever since the first fragments of pterosaur bone surfaced nearly 250 years ago, palaeontologists have puzzled over one question: how did these close cousins of […]

Author: Ari Koeppel, Postdoctoral Scientist in Earth and Planetary Science, Dartmouth College Andy Weir’s bestselling story “The Martian” predicts that by 2035 NASA will have landed humans on Mars three times, perfected return-to-Earth flight systems and collaborated with the China National Space Administration. We are now 10 years past the Hollywood adaptation’s 2015 release and […]

Author: Cédric M. John, Professor and Head of Data Science for the Environment and Sustainability, Queen Mary University of London Nearly three fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth’s oceans were once green, in […]

Scientists have long puzzled over how pterosaurs became the first vertebrates to master flight. Some pterosaur species, such as the Quetzalcoatlus were the largest known animals to ever take to the skies, with wingspans of over ten meters (on par with military aircraft like the Spitfire). My team’s new study may help solve the evolutionary […]

When one tectonic plate sinks beneath another, it generates magmas rich in volatiles such as water, sulphur and chlorine. As these magmas ascend, they release magmatic fluids, in which sulphur and chlorine bind to metals such as gold and copper, and transport these metals towards the surface of the Earth. As the extreme conditions relevant […]

What would happen if humans dried out the Mediterranean sea, turning it into a giant salt lake? Would its wildlife survive, and if so, how long would it take to recover? These may seem like wildly theoretical questions, but not for Herman Sörgel, a Bavarian architect who dedicated much of his life to this exact […]
