Volcanic rocks discovered by Nasa’s Perseverance Mars rover on the floor of the Red Planet’s 3.7-billion-year-old Jezero Crater are offering a tempting clue to how the Martian climate evolved.

It’s part of analysis of the rover’s findings, after it’s spent a year trundling around collecting samples.

Now scientists are trying to work out when and how the igneous rock was formed as strangely there’s no substantial evidence of volcanic activity in the crater.

It’s emerged that while Europe faces a winter of rocketing energy bills, Russia is actually burning off natural gas at the Portovaya plant worth about £8.5 million each day and contributing to the climate crisis.

Experts are trying to get to the bottom of why the gas is being burned, whether it’s linked to trade embargoes over Russia’s invasion of Ukraine, or if there are technical problems at the Gazprom plant requiring the fuel to be “flared” .

University of Cambridge researchers have built model embryos from mouse stem cells that form a brain, beating heart and other foundational body organs. The study is hoped to offer understanding why some embryos fail while others go on to develop into a healthy pregnancy.

Tech & Science Daily spoke to Magdalena Zernicka-Goetz, expert in mammalian development and stem cell biology.

SpaceX and T-Mobile have announced a plan to use satellites to beam phone service to all those nooks and corners that coverage just can’t reach. International Dog Day: Research as part of the Dog Aging Project found that the risk of canine dementia increases by over half each year the animal ages. Twitter has begun testing its new audio experience, which will eventually see podcasts launch alongside Spaces. It’s the day for Samsung’s release of two foldable smartphones, the Galaxy Z Fold 4 and the Galaxy Z Flip 4. Researchers at the French National Institute of Health and Medical Research in Paris say sub-optimal sleep is linked to a heightened risk of heart disease and stroke. And, scientists say new analysis of a seven-million-year-old leg bone fossil found two decades ago in Chad in north-central Africa has revealed it’s actually a relative of us humans that walked on two feet.
