Brain scans reveal which disorders are linked to faster brain aging - Science Daily

RIYADH: The Kingdom has launched the first biological samples from the Middle East to space as part of the BioGravity-1 mission aboard a SpaceX resupply flight to the International Space Station, the Saudi Press Agency reported recently. The launch, led by the Saudi Space Agency and the King Abdullah University of Science and Technology, marks the first phase of a long-term research program aimed at advancing studies into Alzheimer’s disease, multiple sclerosis and other neurodegenerative conditions. The mission was carried into orbit aboard the SpaceX CRS-35 mission to the International Space Station with support from NASA. BioGravity-1 is designed to establish a scientific baseline for future research by sending biological samples from healthy donors into the microgravity environment of space. Researchers will study how cells respond to conditions that cannot be replicated on Earth and examine biological changes linked to aging and neurological diseases. The mission includes two experiments, SSA-1 and SSA-2, developed by KAUST.

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.
