Personifying AI, The Reading Brain, Environmental Sampling Via Bees. April 28, 2023, Part 2

Why Do Humans Anthropomorphize AI?

Artificial intelligence has become more sophisticated in a short period of time. Even though we may understand that when ChatGPT spits out a response, there’s no human behind the screen, we can’t help but anthropomorphize—imagining that the AI has a personality, thoughts, or feelings.

How exactly should we understand the bond between humans and artificial intelligence?

Guest host Sophie Bushwick talks to Dr. David Gunkel, professor of media studies at Northern Illinois University, to explore the ways in which humans and artificial intelligence form emotional connections.

A Bee’s Eye View Of Cities’ Microbiomes

When you want to look at the microbial health of a city, there are a variety of ways to go about it. You might look at medical records, or air quality. In recent years, samples of wastewater have been used to track COVID outbreaks. Studies of urban subway systems have involved painstaking swabs of patches of subway muck. But now, researchers are offering another approach to sample a city’s environment—its beehives.

A report recently published in the journal Environmental Microbiome used the bees foraging in a city to provide information about the town’s bacteria and fungi. The researchers found that by looking at the debris in the bottom of a beehive, they could learn about some of the environments in the blocks around the hives. The microbes they collected weren’t just species associated with flowers and plant life, but included organisms associated with ponds and dogs. The team found that the hive samples could reveal changes from one neighborhood to another in a city, and in the microbial differences between different cities—samples taken in Venice, for instance, contained signals associated with rotting wood that were not seen in samples from Tokyo.

Elizabeth Henaff, an assistant professor in the NYU Tandon School of Engineering at New York University and a co-author of the report, joins SciFri’s Kathleen Davis to talk about what bees and microbes can tell us about the cities we share.

This Is Your Brain On Words

What happens after you pick up a book, or pull up some text on your phone?

What occurs between the written words hitting your eyes and your brain understanding what they represent?

Scientists are trying to better understand how the brain processes written information—and how a primate brain that evolved to make sense of twisty branches and forking streams adapted to comprehend a written alphabet.

Researchers used electrodes implanted in the brains of patients being evaluated for epilepsy treatment to study what parts of the brain were involved when those patients read words and sentences. They found that two different parts of the brain are activated, and interact in different ways when you read a simple list of unrelated words, compared to when you encounter a series of words that builds up a more complex idea.

Dr. Nitin Tandon, a professor of neurosurgery at UTHealth Houston and one of the authors of a report on the work published in the Proceedings of the National Academy of Sciences, joins guest host Sophie Bushwick to talk about the study, and what scientists are learning about how the brain allows us to read.

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
