Summary: Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. Special laser-textured metal panels use sunlight to evaporate water while automatically moving salt deposits away from the working surface, preventing clogging. The process was successfully tested with water from three oceans and can recover nearly all salts as solids. Those leftover materials could even become a source of valuable lithium for batteries.
‘This is a tragedy’: swimming snakes open new front in battle with Balearic lizards
Sam Jones in Madrid
Irrefutable proof of what Spanish researchers and wildlife experts had long suspected, and long feared, finally presented itself in the form of a grainy video that was shot on a minuscule island in the Balearics in April 2024.
Ribboning its way through the turquoise waters that separate the east coast of Ibiza from the islet of Santa Eulària 450 metres away, came a pale and solitary horseshoe whip snake in search of new territory and fresh sustenance.
The arrival of the snake on Santa Eulària, recorded by a local wildlife ranger, confirmed that the insatiable invader from the Spanish mainland – which has almost wiped out Ibiza’s endemic population of dazzlingly coloured wall lizards – had opened up a new front.
“There’d been increasing anecdotal evidence from fishermen and tourists who’d seen the snakes swimming, so we’d thought it was happening very often,” said Oriol Lapiedra, a biologist at the Centre for Ecological Research and Forestry Applications (Creaf) in Catalonia. “But this was the first proper [evidence] we’d had of a snake swimming from Ibiza to the islet.”
The horseshoe whip snake, a non-venomous reptile found across southern and eastern Spain, has become an existential threat to the lizards since it began appearing on the island two decades ago.
Its rapid colonisation has been attributed to the fashion among wealthy property owners in Ibiza for importing ancient olive trees from mainland Spain to adorn the grounds of their homes. Unbeknown to them, however, the trees – replete with their nooks and hollows – have provided ideal travel berths for hibernating snakes and snake eggs. (snip-MORE)
