We dive into the mysterious world of the deep sea, sparked by a recent executive order aiming to ramp up offshore mineral extraction, as well as new research revealing that 99.999 per cent of the seabed remains unexplored. Experts discuss the surprising lack of deep-sea exploration, the ecological wonders already discovered, like hydrothermal vents and bizarre deep-sea creatures, and the debate over mining nodules from the ocean floor. With new battery tech on the horizon and mounting environmental concerns, questions grow about whether deep-sea mining is driven by necessity or a disregard for the ecosystems we barely understand.
Researchers have captured the faint glow emitted by living things to explore what happens when life ends. First theorised a century ago by Russian physicist Alexander Gurwitsch, biophotons are ultraweak light emissions which appear to track metabolism and fade dramatically at death. Could this eerie glow one day help detect disease, or even confirm the moment of death?
Chimpanzees across Africa have been observed rhythmically drumming on trees, but what are they trying to say? A new study spanning 11 chimp communities reveals that these drum beats may be individual signatures, offering fresh insight into the roots of musicality and communication. The team discuss how chimps may even show signs of awe or ritual, with their unique responses to storms, fire, and waterfalls. Could drumming mark not just the evolution of rhythm, but the first flickers of spiritual thought?
