TRANSCRIPT BOB HIRSHON (host): Dreaming up answers. I’m Bob Hirshon and this is Science Update. Many creative thinkers, including artists, musicians and scientists, report getting new insights through dreams. Harvard clinical psychologist Deirdre Barrett studies creative dreaming, and has found that t he dreaming brain specializes in visual-spatial solutions. BARRETT: Problems that start off as visual always get solved in a straightforward visual way in the dream, but things that are more of a word problem or math problem often get represented in images, because that seems to be the part of the mind that’s most active during dreaming. HIRSHON: She says dreams also excel at solving problems requiring outside the box thinking, probably because our prefrontal cortex—the part of the brain that filters out ideas that are silly or inappropriate—is quiet during sleep, allowing unusual ideas to surface. She says visualizing a problem before going to sleep, and having paper, pen and a flashlight on a bedside table frequently yields valuable new insights. I’m Bob Hirshon, for AAAS, the science society. MORE INFO If you want to hear Dr. Barrett discuss sleep in detail, check out this podcast on the Science of Dreaming from the American Psychological Association: A study titled Increased Creative Thinking in Narcolepsy looks at creativity in patients with narcolepsy, a condition characterized by a sudden onset of REM-stage sleep. Since creativity has been associated with this stage of sleep, the authors wanted to see if narcolepsy patients were more creative than a control group. Researchers are also looking at the effects of daytime napping on different types of creativity. And this study looks at our ability to enhance the creativity-boosting qualities of our sleep .

BOB HIRSHON (host): Refining robot social skills. I’m Bob Hirshon and this is Science Update. Making eye contact is an important social skill, but so is occasionally breaking eye contact. That’s true for robots as well. Bilge Mutlu is a professor of computer science, psychology, and engineering at the University of Wisconsin, Madison. His team found that humans were most comfortable talking to robots that glanced away in typical human patterns: to signal the other person’s turn to speak, for example. BILGE MUTLU (University of Wisconsin, Madison): People don’t interrupt the robot when it’s averting its gaze. And both when no aversion, or, sort of badly timed aversions happen, people are more likely to interrupt the robot, they think the robot’s not as thoughtful, and they don’t think that the robot’s behaviors are intentional. HIRSHON: Next, Mutlu says he’d like to teach robots more sophisticated gaze aversion habits: for example, making them respond to changes in eye contact from their human partners. I’m Bob Hirshon for AAAS, the Science Society. —————————— This research was a project of the Human-Computer Interaction Laboratory at the University of Wisconsin–Madison, co-led by Professors Bilge Mutlu and Michael Gleicher, and carried out by graduate student Sean Andrist and undergraduate student Zhi Tan.

Bombardier Beetle Buddies 1:00

Multispecies aggregation. (Schaller et al., 2018 CC-BY) BOB HIRSHON (Host): Bombardier beetle buddies. I’m Bob Hirshon and this is Science Update. Bombardier beetles are bright blue and red, which helps to advertise their fierce defensive arsenal: burning hot toxic chemicals they can spray from nozzles on their butts. In the journal PLOS ONE, University of Arizona entomologist Wendy Moore and her colleagues report that while the nocturnal beetles are solitary at night, many different species shelter together during the day, under rocks. WENDY MOORE (University of Arizona, Tucson): It’s actually a fairly unusual phenomenon for different species to regularly associate with one another. HIRSHON: One reason could be that the different species bring different toxic weapons. MOORE: –that probably contribute to a big chemical cocktail for a vertebrate predator that might find them during the day. HIRSHON: And the huge mass of brightly colored beetles could warn would-be predators to back off. I’m Bob Hirshon for AAAS, the science society.

A male superb lyrebird performs his courtship dance and song. (Alex Maisey) BOB HIRSHON (host): Dancing with the lyrebirds. I’m Bob Hirshon and this is Science Update. (Lyrebird song) This might sound like a shoot-’em up arcade game, but it’s really an Australian bird serenading a female. Superb lyrebirds are known for their prodigious vocal talents. But now, scientists have discovered that the males also impress females by pairing each of their courting songs with a particular dance. Australian National University behavioral ecologist Anastasia Dalziell led the study. ANASTASIA DALZIELL (Australian National University): When they’re dancing they have just four different songs, and with each of those four songs, the lyrebirds have a unique set of dance movements. So depending on what songs they sing, you can predict what kind of dance moves they’re going to perform. HIRSHON: She says as in humans, coordinating dance moves with songs is hard work. So it’s possible that females pick their mates based on their ability to groove. I’m Bob Hirshon, for AAAS, the science society.

BOB HIRSHON (host): Debunking a sticky myth…I’m Bob Hirshon and this is Science Update. Listener Michelle Simms of Alexandria, Virginia says her parents warned her never to swallow chewing gum because it wouldn’t be digested for seven years. We asked Dr. Aaron Carroll, a health services researcher at the Indiana University School of Medicine, if this is true. AARON CARROLL (Indiana University School of Medicine): There’s no truth to the idea that swallowed gum will stay in your stomach for seven years. The body is incredibly good at getting things from one end to the other, even things that aren’t digestible. HIRSHON: Carroll says gum will normally pass through the system in about 24 hours. However, he warns that swallowing very large pieces of gum could cause an emergency blockage. And if you have a science question, give us a call at 1-800-WHY-ISIT. Thmat’s 1-800-949-4748.

2017 total solar eclipse photographed from Warm Springs, Oregon. (Susanne Bard) BOB HIRSHON (host): Buzzing about the eclipse. I’m Bob Hirshon and this is Science Update. The total solar eclipse of August 21, 2017 captivated people across North America, including 5th graders living in the path of totality. The young citizen scientists investigated what bees do when the sun disappears behind the moon. University of Missouri researchers Candi Galen and Zack Miller helped them deploy tiny microphones to record the buzzing of bees in flight before, during, and after the eclipse. Galen says instead of gradually ramping down their buzzing as darkness fell, the bees kept flying. But as soon as totality hit, they stopped. CANDI GALEN (University of Missouri): At that time, the buzzing ceased, which meant that there were no bee flights. That surprised us. HIRSHON: They write in the Annals of the Entomological Society of America that the students continued to learn from their data for months afterwards. Catch the next total solar eclipse on April 8, 2024. I’m Bob Hirshon, for AAAS, the science society. LEARN MORE Story by Susanne Bard The post The 2017 Bee-Clipse appeared first on Science Update .…

A striped skunk. (K. Theule/USFWS/CC BY 2.0, via flickr) BOB HIRSHON (host): Skunk vs skunk. I’m Bob Hirshon and this is Science Update. [ Pepé LePew clip ] The cartoon skunk Pepé LePew was oblivious to his own stink, and listener Arthur Magida wonders whether skunks in general are immune. We asked University of New Mexico skunk researcher Jerry Dragoo. He says that skunks and other members of the order Carnivora, including dogs, don’t seem to mind the smell. But they are still repelled because the spray is an irritant. JERRY DRAGOO (University of New Mexico): If one skunk gets sprayed by another one, and it hits him in the face, gets him in the eyes, they do go through a lot of the typical behaviors you could see a dog do, you know, rub their face in the dirt, put their paws up to their face and rub it a little bit, so they are definitely affected by it when another animal sprays them.

The solar arrays on NASA’s InSight lander, eventually bound for Mars, inside a clean room at Lockheed Martin Space Systems, Denver. (NASA/JPL-Caltech/Lockheed Martin) BOB HIRSHON (host): Spacecraft hygiene. I’m Bob Hirshon and this is Science Update. The NASA Office of Planetary Protection is sort of a high-tech janitorial service cleaning and checking spacecraft for bacteria and their tough spores. Betsy Pugel is deputy to the Planetary Protection Officer. BETSY PUGEL (NASA): So that when something goes to Mars, or Enceladus, places that may have life, that we know what we’re taking along in terms of a biological load. HIRSHON: But she says no matter how carefully they scrub, some spores manage to survive. PUGEL: Nature always finds a way. You think you’ve cleaned something to the nth degree and somehow, somewhere there’s something that manages to persist. HIRSHON: In fact, the extreme efforts the group takes to disinfect the spacecraft have led to the discovery of new types of super-tough microorganisms that survive their efforts — clues to the very sorts of microbes that might live on other worlds.

A praying mantis munches on a guppy it caught in an artificial pond in India. (Rajesh Puttaswamaiah) BOB HIRSHON (host): A guppy-munching insect. I’m Bob Hirshon and this is Science Update. Giants among insects, praying mantises have been observed to gobble up frogs , rodents, and even small birds. Now, researchers report in the Journal of Orthoptera Research that fish can be added to that list. Italian entomologist Roberto Battiston of the Musei del Canal di Brenta has been working with the insects for 20 years. ROBERTO BATTISTON ( Musei del Canal di Brenta / Museums of the Canal of Brenta): So I was quite surprised because it is the first time heard about mantis feeding on a fish. HIRSHON: He says colleagues in India first alerted him to the unusual behavior via social media. They documented the mantis climbing onto pond vegetation to grab the guppies at night. BATTISTON: They have very sharp mandibles, so they basically cut the fish like a Japanese chef. HIRSHON: Battiston says the insects have large brains and may actually learn to fish through repeated experience. I’m Bob Hirshon for AAAS, the science society. Original source: Battiston R, Puttaswamaiah R, Manjunath N (2018) The fishing mantid: predation on fish as a new adaptive strategy for praying mantids (Insecta: Mantodea).
