Severed bow of US warship finally found in the South Pacific

The bow section of the US warship USS New Orleans, which was blown off by a Japanese torpedo in 1942, has been located near the island of Guadalcanal in the South Pacific. Although the ship survived the attack, more than 180 of the crew on board the heavy cruiser were killed when one of the ship's magazines of ammunition was hit by a torpedo and detonated, tearing off the front of the vessel.

Scientists transform urine into material fit for medical implants

Scientists have developed a method that can transform human urine into the hard mineral in bones and tooth enamel. The research, funded by the US military's Defense Advanced Research Projects Agency (DARPA), uses yeast to break urine down into hydroxyapatite, a form of calcium used in bone and dental implants. And hydroxyapatite isn't useful only for implants; the researchers behind the study said the material could be used in archaeological restoration, as biodegradable alternatives to plastic and as building materials for construction projects.

World's first planned migration of an entire nation

More than 5,000 people have applied for a first-of-its-kind migration visa that offers residents of a Pacific island an escape from the worst effects of climate change. Applications for the visa closed to people in Tuvalu on 18 July. Under its terms, 280 Tuvaluans can relocate to Australia each year from 2025 through a ballot system. Four days after the ballot opened, 3,125 Tuvaluans, roughly one-third of the nation's population of 11,000 people, had already registered for a chance to receive the visa. “This is the first agreement of its kind anywhere in the world, providing a pathway for mobility with dignity as climate impacts worsen,” Australian government representatives said. The representatives said that they recognised the “devastating impact climate change is having on the livelihoods, security and well-being of climate-vulnerable countries and people, particularly in the Pacific region.”

The world's dams hold so much water they've shifted Earth's poles

The construction of thousands of dams since 1835 has caused Earth's poles to wobble, new research suggests. Scientists found that large dams hold so much water, they redistribute mass around the globe, shifting the position of Earth's crust relative to the mantle, the planet's middle layer. Earth's mantle is gooey, and the crust forms a solid shell that can slide around on top of it. Weight on the crust that causes it to shift relative to the mantle also shifts the location of Earth's poles. \"Any movement of mass within the Earth or on its surface changes the orientation of the rotation axis relative to the crust, a process termed true polar wander,\" researchers wrote in the journal Geophysical Research Letters.

BURMESE PYTHONS HAVE CELLS THAT HELP THEM DIGEST ENTIRE SKELETONS

Researchers found that specialised cells in Burmese pythons' intestinal lining process calcium from the bones of their meals. This helps explain how these predators digest whole prey.
