A new study has revealed that pilot whales are "the cheetahs of the deep sea," making high-speed, all-or-nothing dives to chase and catch large prey before surfacing to catch their breath. Such sprinter-like dives stand in stark contrast to the longer, slower, and more conservative dives of other whale species that have been studied. Marine mammal researchers working off the Canary Islands attached non-invasive, temporary tags, known as D-tags, to 23 whales to digitally record movements during their 15-minute dives, as well as the sounds that they make and hear. Researchers analyzed the recorded "clicks," "buzzes," and other whale sounds, together with the whales' recorded speeds, orientations, and depths, to reconstruct a picture of the whales' hunts. The tags recorded movement, sound, and depth for one day, after which they disconnected and floated to the surface for collection.
Freedom from suffering is not only possible, but the means for achieving it are immediately within our grasp—literally as close to us as our own breath. This is the 2,500-year-old good news contained in the Anapanasati Sutra , the Buddha's teaching on cultivating both tranquility and deep insight through full awareness of breathing. In this book, Larry Rosenberg brings this timeless meditation method to life. Using the insights gained from his many years of practice and teaching, he makes insight meditation practice accessible to modern practitioners.
Meet Trevor Hutton, a South African freediver. Diving as deep as possible on one breath is a dangerous but exhilarating business, and in Deep Blue Dive we follow Trevor as he negotiates the hostile South African coastline, the ocean swells and dangerous marine life that inhabit his local waters. Trevor is self-trained but South Africa has always cautioned against the sport, and for good reason. But something incredible happens to this six-feet-plus man as he enters the water. We’ll watch as nerve receptors in his heart trigger oxygen-saving responses in his body, slowing his heart down by 50 per cent. Blood vessels constrict, his spleen shunts red blood cells into his bloodstream to prepare for a lack of oxygen and a litre of blood floods into the chest. His body turns into a deep diving machine.
