#262 Geologists have just drilled deeper into Earth’s mantle than ever before. The hole is in an area of the ocean called Atlantis Massif, where the upper mantle is exposed. Reaching 1268 metres deep, this incredible sample core could help uncover secrets to the very origins of life. Ancient human ancestors called Homo floresiensis and known as the “hobbits” may have evolved their short stature much faster than expected. Remains found on the Indonesian island of Flores suggest a much older group of hominins may have been slightly smaller, averaging just 1 metre tall, and possibly the ancestors of Homo floresiensis. How could this change the story of our mysterious cousins? Quantum telepathy may allow stock market traders to act faster and get richer. Using quantum entanglement, coordinating transactions in distant stock exchanges could happen faster than the speed of light. And surprisingly, this type of technology wouldn’t be hard to get up and running – so what happens if someone tries it? If we want to move to Mars one day, we have to make it a bit more enticing to live on. Ideas to terraform the Red Planet, or make it more Earth-like, have mostly been too expensive and unworkable. A method involving glittery clouds could be the answer to coaxing better conditions for human life.  Plus: The microbes and bacteria that can survive the harsh heat of your microwave; how the microbiome of a baby horse impacts its racing performance in adulthood; and the special trick leeches use to hunt the ultrafast blackworm. Hosts Christie Taylor and Timothy Revell discuss with guests Chen Ly, Sam Wong, Karmela Padavic-Callaghan and Alex Wilkins. To read more about these stories, visit newscientist.com. Hosted on Acast.
