A 100 million year old ichthyosaur dug out of the ground near Richmond in outback Queensland was scanned in three dimensions, and the stony nodules beside it turned out to be its last meal, a pterosaur. The ichthyosaur had in turn been eaten by a pliosaur, leaving a three-tier Cretaceous food chain in a single specimen. The study ran in Gondwana Research on 27 July.
Researchers at University of Utah Health programmed the CRISPR enzyme Cas12a2 to recognise the mutated KRAS gene and then tear a cell's DNA apart rather than edit it. Human lung cancer cell growth halved in the dish, cells carrying healthy KRAS were left untouched, and tumours in mice slowed. The work is published in Nature.
Romina Pourmokhtari, Sweden's climate and environment minister, set 1 January 2028 as the date PFAS must leave clothing, shoes, waterproofing agents, kitchenware, cosmetics and ski wax. The national ban runs well ahead of the European Commission, which is not expected to propose EU-wide restrictions until 2027.
Jane and Winnie have joined Hilo, a veteran of more than a decade, on Alberta's invasive mussel patrol, picking up zebra, quagga and golden mussel larvae in the parts of a boat an inspector cannot reach. The province runs 12 inspection stations on its borders, checked 21,995 boats last year and has stopped six infested craft this season.
