Unique seal swimming patterns could inspire new underwater drones

Unique seal swimming patterns could inspire new underwater drones This competition is now closed Unique seal swimming patterns could inspire new underwater drones Advertisement While biologists have long known that seals and sea lions have had two different methods for swimming, the reason behind this has been a mystery. By using cutting-edge engineering alongside footage of animal behaviour, scientists can now explain the origins of efficient swimming in the animals. Seals and sea lions are fast-swimming ocean predators that use their flippers to “fly” through the water. But not all seals are the same – some use their front flippers to swim, while others propel themselves with their back feet.

Engineers and biologists join forces to reveal how seals evolved to swim

Researchers have discovered how seals and sea lions evolved to swim. The findings could have potential implications for improving the design of man-made machines such as underwater drones and submersibles. Using cutting-edge engineering and animal behaviour, scientists have explained the origins of efficient swimming in the animals. Seals and sea lions are fast-swimming ocean predators that use their flippers to “fly” through the water. But not all seals are the same – some use their front flippers to swim, while others propel themselves with their back feet. Fur seals and sea lions have wing-like front flippers specialised for swimming, while grey and harbour seals have stubby, clawed paws and swim with their feet.

Oh, by the way, I can t have children, so we re going to have to adopt – how do you put that in your Tinder profile?

Nikki Bradley feels it’s important to have conversations on the impact cancer treatment can have on people At the time, this wasn’t a huge blow, she reflects. “I was only 19, kids weren’t on my radar at all; I was so keen to just get back to normal.” In 2006, sitting at her kitchen table studying for her Leaving Certificate mocks, she felt a twinge in her hip. As the day went on the pain increased. Nikki ended up in hospital that evening on morphine. Three weeks in bed followed, with Nikki virtually unable to move. “I can’t fully describe how bad the pain was,” she says. She spent 10 weeks in St Vincent’s where doctors investigated the source of her pain. Nikki had been left with lymphedema and scar tissue after her cancer treatment, which somewhat blocked scans. An infection was suspected. She was sent home and had to wait another year before receiving her hip replacement in the summer of 2007. The bone had essentially started to crumble due to the treatment, and
