  Lund, Sweden (SPX) Jun 05, 2018 Millions of years of evolutionary fine-tuning have made dolphins phenomenally good at using echolocation to orient themselves, find food and communicate with one another. But how do they actually do it? New research from Lund University in Sweden shows that they emit two intertwined ultrasound beam components at different frequencies - and with slightly different timing. This new knowledge brings us one step closer to solving the puzzle. Josefin Starkhammar, a researcher in biomedical engineering ... read more |
