During the Second World War, the British Royal Navy experimented with the idea of using ice reinforced with wood pulp to build an aircraft carrier. The composite material, known as Pykrete, was apparently as strong as concrete, as long as it could be kept frozen. The ship would've effectively been a floating, custom-made, strengthened iceberg for planes to take off from and land on – but with rising costs and better options becoming available, the project was eventually abandoned. Now researchers led by a team from the Hebrew University of Jerusalem in Israel have extended that idea from the 1940s to create what they're calling BioPykrete. By adding plant-based crystals and a bespoke protein to ice, they've created something that's 10 times stronger than regular ice and able to absorb 70 times more energy before breaking. A study of the new material has been published in Colloids and Surfaces B: Biointerfaces, and the team behind it hopes that it may one day be used as a building material. A sample of the new ice.

Orcas are hunting great White Sharks around the world, scientists confirm - Geo News
Orcas are hunting great White Sharks around the world, scientists confirmThe killing of great whites by orcas has been reported in the waters of South Africa, California, and Australia, and the implications that the hunting behaviour would have on the marine ecosystem have been considered. In fact, it all started back on May 3, 2017, when the body of a female great white, weighing 1,100 kilograms, washed ashore in Gansbaai, close to Cape Town, with a deep gash through which its 90-kilogram liver had been extracted. Five more corpses of great whites appeared with similar wounds in the coming months, as claimed by shark biologist Alison Towner of Rhodes University. Two adult males, called Port and Starboard, who are supposed to be brothers judging by their dorsal fins that fold differently, were identified as the most probable perpetrators. The connection was officially established in 2022 based on video footage of a drone that caught three orcas chasing and biting a 3-meter great white off Mossel Bay. The sharks quickly disappeared from Dyer Island, one of the best places in the world to witness a great white.
