BBC's Shortwave shares captivating science stories and productivity tips: Listeners learned about albatross navigation, ancient animal discovery, Orionid meteor shower enjoyment, and productivity tools from sponsors Integrative Therapeutics and Slack
The BBC provides valuable information and inspiration through storytelling, encouraging listeners to think for themselves. During this episode of NPR's Shortwave, Elsa Chang shared intriguing science stories, including how albatrosses use sound for navigation and a rare discovery of two animals interacting on the ocean floor 480 million years ago. Additionally, listeners were given a hint about the best way to enjoy the Orionid meteor shower. The sponsor messages featured Integrative Therapeutics, offering clinician-curated supplements now available on Amazon, and Slack, an AI-powered platform for businesses to increase productivity with features like impromptu meetings and task automation. Overall, this episode of Shortwave, sponsored by the BBC, showcased fascinating stories and useful tools to make listeners think and grow.
Albatrosses use infrasound for ocean navigation: Researchers found that albatrosses navigate the open ocean using infrasound, a low frequency sound wave, marking the first time this has been identified for seabirds.
Researchers have discovered that wandering albatrosses use infrasound, low frequency sound waves, to navigate over the open ocean. This new finding adds to the existing knowledge that some animals, like elephants and certain whales, use infrasound for communication. However, this is the first time that infrasound has been identified as a potential navigational cue for seabirds. The researchers created acoustic maps of the ocean using data from a network of microphones to detect this phenomenon. Infrasound is created when waves collide with each other and is prevalent in the ocean environment. This discovery sheds light on the fascinating ways that animals, even those as large as albatrosses, are able to navigate and survive in the vast open ocean.
Birds use infrasound for better flying conditions navigation: Birds navigate using low-frequency sound waves, enhancing their flying abilities by detecting strong winds and waves. This discovery has potential implications for weather predictions and climate modeling.
Birds use infrasound, low-frequency sound waves, to navigate towards areas with strong waves and wind for better flying conditions. This is the first study to show animals using infrasound for navigation. Birds rely on wind for soaring, and choppy, wavy areas provide more wind and updrafts. Additionally, waves crashing against a shoreline create infrasound, which could also help birds find their way home. This discovery has implications for human use of infrasound in improving weather predictions and climate models. Meanwhile, a fascinating fossil discovery from 480,000,000 years ago reveals how ancient cephalopods and sea worms coexisted. A cephalopod with a shell died and fell to the seafloor, where sea worms built tough tube-like houses on its shell. This discovery sheds light on ancient marine ecosystems and how organisms interacted with each other and their environment. These findings highlight the complex and intriguing ways animals navigate and interact with their environments, both above and below water.
Ancient marine ecosystem discovery and Orion meteor shower: Studying ancient marine fossils and observing meteor showers offers insights into the natural world and survival strategies during mass extinctions, as well as the wonders of the cosmos
The fossil discovery of a whole colony of ancient worms interacting with a dead cephalopod is a significant find, as it provides a rare glimpse into ancient marine ecosystems and the strategies used by organisms to survive mass extinctions. Additionally, the Orion meteor shower, peaking this weekend, is a natural phenomenon worth staying up late for, as it offers the opportunity to witness pieces of Halley's Comet burning up in the Earth's atmosphere. The fossil discovery and meteor shower both highlight the intrigue and importance of studying both the natural world and the cosmos.
Orion Meteor Shower: A Bright and Speedy Spectacle: Find a dark location, give eyes time to adjust, and be patient for approximately 20 visible meteors per hour during the Orion Meteor Shower, named after the constellation Orion, for optimal viewing.
The Orion meteor shower is an annual event caused by the debris left behind by Halley's comet. These meteors are known for their brightness and speed, leaving glowing trails that can last for several seconds to minutes. To best view this shower, find a dark location away from city lights, give your eyes time to adjust, and be patient as the shower produces approximately 20 visible meteors per hour. The Orionids get their name from the constellation Orion and can be seen all across the night sky. For optimal viewing, avoid interruptions by becoming a subscriber to NPR's Shortwave Plus.
