What if The Brain Doesn't Create Consciousness? Scientist Proposes It Might Be The Fabric of Reality Itself - ScienceAlert

Here’s what you’ll learn when you read this story:For nearly 40 years, scientists have debated whether some aspects of consciousness are non-computational, and therefore, quantum in nature. While regarded as controversial and fringe for decades, evidence hasn’t entirely refuted the theory, and its core ideas are generating more and more attention. Recent studies have provided compelling evidence that quantum processes, with microtubules in neurons serving as a substrate, play a role in human consciousness. The rise of consciousness in humans and all living beings is arguably the greatest wonder of the natural world—and it’s also one of its biggest mysteries. Over millennia, theologians, natural philosophers, and neuroscientists have put forward their own ideas about how this phenomenon arises within our minds, and by the tail end of the 20th century, one of these new theories raised more than a few eyebrows. This interest was warranted for a couple of reasons. First, the person proposing the idea was Roger Penrose, English mathematician and Nobel Laureate. And the second? Well, it involved the most devilishly complex of all scientific fields: Quantum theory.

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.
