Showing results by narrator "David Drummond" in Science & Engineering

How does the brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind a conscious state.

In early May 2006, a young British climber named David Sharp lay dying near the top of Mount Everest while forty other climbers walked past him on their way to the summit. A week later, Lincoln Hall, a seasoned Australian climber, was left for dead near the same spot. Hall's death was reported around the world, but the next day he was found alive after spending the night on the upper mountain with no food and no shelter.

Alexander von Humboldt (1769-1859) is the great lost scientist: more things are named after him than anyone else. There are towns, rivers, mountain ranges, the ocean current that runs along the South American coast; there's a penguin, a giant squid - even the Mare Humboldtianum on the moon. His colourful adventures read like something out of a Boy's Own story.

As Carl Safina's compelling natural-history adventure makes clear, the fate of the leatherback turtle is in our hands. The distressing decline of these ancient sea turtles in Pacific waters and their surprising recovery in the Atlantic illuminate the results - both positive and negative - of our interventions and the lessons that can be applied, globally, to restore the oceans and their creatures. We accompany award-winning natural-history expert Safina and his colleagues as they track leatherbacks across the world's oceans and onto remote beaches of every continent.
