Covering the outer reaches of space to the tiniest microbes in our bodies, Science Friday is the source for entertaining and educational stories about science, technology, and other cool stuff.


Science Friday

Just about <a href="https://www.sciencedirect.com/science/article/pii/S0003347222000719" target="_blank" rel="noopener noreferrer">every animal</a> with a backbone yawns (maybe even dinosaurs), but why we do it is still something of a mystery. A SciFri listener from Texas recently spotted some <a href="https://www.sciencedirect.com/science/article/pii/S1569904826000340" target="_blank" rel="noopener noreferrer">research that suggests</a> yawning could play a role in clearing waste products from the brain, and asked us to get to the bottom of it. Biomechanical engineer Lynne Bilston, an author on that study, joins Flora to <a href="https://www.sciencefriday.com/segments/why-we-yawn-brain-waste-cleaning?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">discuss the findings</a> and what they could mean for neurodegenerative diseases like Alzheimer's.
Plus, about a third of Americans aren’t getting the recommended seven hours of sleep per night, according to a <a href="https://www.cdc.gov/nchs/products/databriefs/db559.htm" target="_blank" rel="noopener noreferrer">new CDC report</a>. We check in with sleep researcher Stuti Jaiswal to break down the report and find out how to get a better night's sleep.

How yawning might help clear dirty fluid from the brain

An upcoming resupply mission will carry tumor samples to the International Space Station for research. Experiments in microgravity have yielded shocking results: Some tumors triple in size in just 10 days—the kind of growth that could take 10 years on Earth. What does that mean for science, and for astronauts? 
Joining Ira to discuss this new frontier in <a href="https://www.sciencefriday.com/segments/cancer-research-space-microgravity-tumors?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">cancer research</a> are hematologist Catriona Jamieson and aerospace engineer Meenal Datta.

Who's composing music for my washing machine?

Scientists studying climate models say there’s a high chance this will be <a href="https://www.sciencefriday.com/segments/super-el-nino-weather-trends/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">an El Niño year</a>—and that we could be in for a “super” El Niño. The difference is indicated by sea surface temperatures in part of the Pacific Ocean rising a little—or a lot—above their long-term average.
El Niño is one half of what climatologists call the ENSO, the El Niño-Southern Oscillation. The oscillation operates on a roughly 3-7 year cycle, changing the path of the jet stream and shifting weather conditions around the world. An El Niño year, for instance, typically brings wetter weather in the western U.S. but dryer conditions in the Pacific Northwest, and can be a drought buster for regions such as southern California.  But shifting ocean currents also have the potential to affect marine ecosystems, leading to algal booms, coral bleaching, and more.  
Climate scientist Dillon Amaya joins Host Ira Flatow to describe the role of the El Niño in shaping world weather, and what effects a particularly strong El Niño year might have on global ecosystems.
Guest: 
Dr. Dillon Amaya is a research scientist at the NOAA Physical Sciences Laboratory in Boulder, Colorado.

Planning your photo ops for a trip around the moon

When Kemi Doll was in medical school, she learned that Black women are twice as likely to die from uterine cancer as white women, and also suffer disproportionately from other uterine-related conditions. What wasn’t explained was why. Now a gynecologic oncologist, Doll has made it her mission to change these trends and <a href="https://www.sciencefriday.com/segments/gynecologic-health-crisis-for-black-women-improving-uterine-health/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">improve care for Black women</a>. 
She joins Flora to discuss her new book, “<a href="https://bookshop.org/a/18570/9780593977477" target="_blank" rel="noopener noreferrer">A Terrible Strength: The Hidden Crisis of the Black Womb and Your Survival Guide to Healing.”</a> They explore the way systemic racism and the normalization of Black women’s pain lead to later diagnoses of uterine cancer and poorer health outcomes for a range of gynecologic conditions including fibroids, endometriosis, and heavy periods. And Doll explains the problem with using reproductive health as a synonym for uterine health. 
Guest: 
Dr. Kemi Doll is a gynecologic oncologist and professor at the University of Washington Schools of Medicine and Public Health.

Data about your body is up for sale. Who's buying it?

Breaking news out of eastern Oklahoma! A hole in the sky has opened. Through it, an unidentified turtle-shaped craft has descended. Alerts say that this is first contact. 
So it goes in <a href="https://www.sciencefriday.com/segments/sci-fi-thriller-combines-aliens-robots-and-cherokee-culture/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">the sci-fi thriller</a> “Hole in the Sky.” In the book, author Daniel H. Wilson imagines this moment where we meet alien life for the first time. It’s set in the heart of Cherokee Nation and follows characters including a military man, a NASA scientist, and a Cherokee father named Jim who is just trying to survive the alien entity.
Wilson joins Flora for a conversation about the book and how he integrated elements of Cherokee culture with science fiction. They get into the ways we project our own fears—like genocide and slavery—onto aliens, and how science fiction helps us imagine the unimaginable.

Beavers could be humans' biggest ally, if we let them

Deep in an active nickel mine near Sudbury, Ontario, researchers are installing and calibrating a set of sensitive detectors. They hope that the location roughly 6,800 feet underground will screen out much of the ordinary radiation and cosmic rays felt on the surface, and allow their detectors to sense tiny disturbances caused by a dark matter particle passing close to the nucleus of one of the germanium atoms in a target material.
If successful, the <a href="https://www.sciencefriday.com/segments/searching-for-dark-matter-deep-in-the-earth?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">SuperCDMS SNOLAB experiment</a> may shed some light on the nature of dark matter, an unseen something that is thought to make up around 85% of the matter in the universe.
Priscilla Cushman, a physicist who has been working on the project for over 20 years, joins Host Flora Lichtman to describe the hunt, the timeline of the experiment, and the big unknowns facing the SuperCDMS team. 
Guest: 
Dr. Priscilla Cushman is spokesperson for the SuperCDMS SNOLAB experiment, and a professor in the School of Physics and Astronomy at the University of Minnesota.

Searching for dark matter, deep in the Earth

Hurricane season officially begins in June. And in the event of a big storm, local and state governments often rely on help from the Federal Emergency Management Agency or <a href="https://www.sciencefriday.com/segments/decades-long-movement-to-kill-fema?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">FEMA</a>. But, President Trump has questioned the value of the agency.  
“I've never been a big fan of FEMA. I like to keep it local. I like to see governors and neighboring states help each other as opposed to FEMA,” Trump said in March.
We’ve heard this from the administration about other federal agencies, but FEMA is a special case. People have mistrusted this agency since its founding in the late 1970s.  
Host Flora Lichtman talks with Micah Loewinger, co-host of the show “On The Media,” who traced FEMA’s history in a new series called <a href="https://www.wnycstudios.org/podcasts/otm/american-emergency-movement-kill-fema" target="_blank" rel="noopener noreferrer">“American Emergency: The Movement to Kill FEMA.”</a>

The decades-long movement to kill FEMA

Animal neuroaudiologist Pete Scheifele joins us to answer some burning questions from SciFri listener Paul: Why can dogs and cats hear a wider range of frequencies than we do? Is it in their ears, their brains? And what would life be like if you had dog ears or cat ears?
And, scientists have created the first <a href="https://www.sciencefriday.com/segments/animal-hearing-smell-map/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">“smell map”</a> of the nose using a mouse model. Host Flora Lichtman talks with neurobiologist Bob Datta about this latest research, and what it tells us about olfaction.
Guests: 
Dr. Pete Scheifele is a neuroaudiologist at the University of Cincinnati and executive director of the FETCHLAB, an animal audiology clinic and lab.
Dr. Bob Datta is a neurobiologist at Harvard Medical School.
