Planet Oat's oat milk offers a rich and creamy experience with added calcium, vitamins A and D, and unsweetened varieties contain no sugar. During this episode of NPR's science podcast, Shortwave, hosts Regina Barber, Ari Shapiro, and Rachel Carlson discuss three intriguing science stories. The first is about black-capped chickadees, known for their impressive memory abilities. Second, robots are becoming more advanced, anticipating human smiles. Lastly, insects and poetry, specifically haiku, are intertwined in a unique scientific exploration. Enbridge invests over a billion dollars annually in renewable energy and lower carbon solutions, while Mint Mobile offers affordable wireless plans to help navigate inflation.
Birds Use Unique Brain Patterns to Remember Seeds Like a Barcode System: Researchers discovered birds use unique brain patterns to remember seed locations, providing a new framework for understanding memory binding in both birds and humans. Robots are advancing in verbal communication but now also mimic human emotions, including smiling, for more engaging human-robot interactions.
Birds, like chickadees, use unique brain patterns to remember the location of hidden seeds, much like a barcode system. Researchers discovered this by observing the neural activity in the birds' hippocampus, a brain region crucial for memory. Each time a bird hid a seed in a specific location, a unique brain pattern emerged. This pattern, or "barcode," was identified through small probes inserted in the birds' brains. The barcode was more connected to the experience than the place, as it only appeared when the bird successfully retrieved the seed. This discovery could provide a new framework for understanding how the brain binds together various elements, such as time, place, and context, into a single memory for both birds and humans. In another realm, robotics have made significant strides in verbal communication using AI. However, communication between robots and humans can be more complex and sophisticated than just words. Enter the robot that smiles, a development that might sound eerie but is an essential step towards more human-like interaction. This robot, named Replika, was designed to learn from interactions with its human counterparts and mimic their emotions, including smiling. This advancement in robotics could lead to more nuanced and engaging human-robot interactions, potentially revolutionizing industries such as healthcare, education, and customer service.
Creating a robot that learns human emotions: Columbia University researchers developed a robot named Emo, which uses AI to learn human emotions and respond with facial expressions, moving towards realistic robots that could be useful for caretaking and beyond.
A team of roboticists at Columbia University has created a new kind of robot named Emo, which uses AI to learn facial expressions and smile in response to human emotions. This is significant because it's a step towards overcoming the uncanny valley, the eerie feeling people experience when interacting with robots that are almost human but not quite. Emo is still in its early stages, but it's a start to creating realistic robots that could be useful for caretaking and other applications. The robot's ability to learn and respond to human emotions makes it feel more alive and in sync with humans, taking the illusion of aliveness to a whole new level. Researchers believe that as Emo and similar robots continue to develop, they could help overcome the uncanny valley and make robots more accepted and integrated into society. Emo is not meant to be human, but rather a new species, and its potential uses go beyond just caretaking. However, it's important to remember that this technology is still in its infancy and there are many ethical considerations to be addressed as it develops.
Haikus about Arthropods: A Focus on Butterflies and Overlooked Aquatics: Butterflies are commonly referenced in haikus, but aquatic arthropods, essential to ecosystems, are often overlooked.
Haikus, originating in Japan, have evolved and adapted to various languages and cultures, often depicting moments in nature, including arthropods. A recent study by researchers at Penn State's Frost Entomological Museum analyzed thousands of English haikus referencing arthropods, finding that Lepidoptera, or butterflies and moths, are the most frequently mentioned. For instance, the haiku "Fresh scooped mud from the little ditch, a little flitting butterfly" references the behavior of butterflies called puddling, where they suck up liquids from mud or river banks for essential nutrients. However, the study also revealed that aquatic arthropods, such as crayfish and various insects that live part of their life cycle in water, are often overlooked in haikus. Despite their importance to ecosystems, these aquatic arthropods received few or zero mentions in the analyzed haikus. So, the next time you write or read a haiku, consider incorporating the often-overlooked aquatic arthropods to add more depth and accuracy to your nature-inspired poetry.
Annual Hexapod Haiku Challenge at Frost Entomological Museum: Explore the power of poetry through the annual Hexapod Haiku Challenge, focusing on aquatic arthropods. Listen to Ari's story on NPR's Consider This podcast and support NPR sponsors Easycater and Capella University.
The Frost Entomological Museum is currently hosting its annual Hexapod Haiku Challenge, which is free for anyone to enter, and this year includes a special category for aquatic arthropods. This means you have the opportunity to highlight the importance of stoneflies, crayfish, and other water-dwelling insects. This brings us back to a personal story shared by the guest, Ari, about winning a poetry contest as a child, showcasing the power of poetry and creativity. Additionally, listeners were reminded of NPR's afternoon news podcast, Consider This, where Ari can be heard. A shout-out was given to Shortwave Plus listeners, who help support the show. Easycater and Capella University were introduced as NPR sponsors. Lastly, listeners were encouraged to visit npr.org/podcast to discover their next favorite show, with a variety of topics available.
