Battling bias in medicine, and how dolphins use vocal fry
On this week’s show: Researchers are finding new ways to mitigate implicit bias in medical settings, and how toothed whales use distinct vocal registers for echolocation and communication
First up this week: how to fight unconscious bias in the clinic. Staff Writer Rodrigo Pérez Ortega talks with host Sarah Crespi about how researchers are attempting to fight bias on many fronts—from online classes to machine learning to finding a biomarker for pain.
Next up on the show: a close look at toothed whale vocalization. Though we have known for more than 50 years that toothed whales such as orcas, sperm whales, and dolphi...

How an increased heart rate could induce anxiety in mice
00:47 How a racing heart could trigger anxietyAnxiety can make the heart beat faster, but could the reverse be true as well? That question has been much debated, but hard to test. Now, a team has shown that artificially increasing a mouse’s heart rate can induce anxiety-like behaviours, and identified an area in the brain that appears to be a key mediator of this response. They hope that this knowledge could help to improve therapies for treating anxiety-related conditions in the future.Research article: Hsueh et al.News & Views: How an anxious heart talks to the brain08:32 Research HighlightsThe chance discovery of ...

BS 205 is a follow-up interview with molecular biologist Dr. Guy Caldwell we learn more about how the tools of molecular biology are used to unravel questions in neurobiology and provide hope for better treatments for problems like Parkinson's Disease.We learn about how gene editing techniques are used test the effects of single nucleotide changes in the neurons of the roundworm C. Elegans. This is possible because humans and C. Elegans share many genes. This makes it possible to economically explore a wide range of possibilit...

Is Meditation a "Mind Science?" with Evan Thompson (BS 202)
Brief Audience Survey
Evan Thompson (click to play, right click to download mp3
The idea that meditation is a "mind science" is popular, but in this interview Canadian philosopher Evan Thompson argues that this claim does not stand up to either scientific or philosophical scrutiny. As one of the pioneers of the Embodied Cognition movement Thompson reminds us that the Mind is not restricted to the Brain and we must also consider how ot...

Kurt Vonnegut ’s contribution to science, and tunas and sharks as ecosystem indicators
On this week’s show: How sci-fi writer Kurt Vonnegut foresaw many of today’s ethical dilemmas, and 70 years of tunas, billfishes, and sharks as sentinels of global ocean health
First up this week on the podcast, we revisit the works of science fiction author Kurt Vonneugt on what would have been his 100th birthday. News Intern Zack Savitsky and host Sarah Crespi discuss the work of ethicists, philosophers, and Vonnegut scholars on his influence on the ethics and practice of science.
Researchers featured in this segment:
Peter-Paul Verbeek, a philosopher of science and technology at the University of Amsterdam and ...

This month's episode of Brain Science is an interview with WA (Bill) Harris, author of Zero to Birth: How the Human Brain Is Built. We explore how the human brain develops from the fertilized egg up until birth. There are some surprises along the way, including the fact that we actually have more neurons before we are born than we will ever have agai...

Space-based solar power gets serious, AI helps optimize chemistry, and a book on food extinction
On this week’s show: Cheaper launches could make solar power satellites a reality, machine learning helps chemists make small organic molecules, and a book on the extinction of foods
First up on the podcast, space-based solar power gets closer to launch. Staff Writer Daniel Clery talks with host Sarah Crespi about how reusable rockets bring the possibility of giant solar array satellites that beam down gigawatts of uninterrupted power from space.
After that, we hear about small organic molecule synthesis. Making large organic molecules such as proteins and DNA can be a cinch for chemists, but making new smaller organic...

Human brain organoids implanted into rats could offer new way to model disease
In this episode:00:45 Implanted brain organoids could offer new insights into diseaseBrain organoids — lab-grown, self-organizing structures made of stem cells — are used in research to better understand brain development and disease progression. However, these structures lack connections seen in real brains, limiting their usefulness. To overcome this, a team has now transplanted human organoids into the brains of newborn rats, showing that these implanted organoids respond to stimuli and could influence the animals’ behaviour.Research article: Revah et al.News and Views: Human brain organoids influence rat behaviou...

This month's episode of Brain Science is an interview with Batja Mesquita, author of Between Us: How Cultures Create Emotions. This is an important book because it describes the evidence that Emotions are not just something people experience "from the inside out," but they also occur between people, which means that culture plays a critical role. We also explore why it is important to appreciate why people from from different cultures may experience emotions in surprisingly different ways.

Monitoring a nearby star ’s midlife crisis, and the energetic cost of chewing
On this week’s show: An analog to the Maunder Minimum, when the Sun’s spots largely disappeared 400 years ago, and measuring the energy it takes to chew gum
We have known about our Sun’s spots for centuries, and tracking this activity over time revealed an 11-year solar cycle with predictable highs and lows. But sometimes these cycles just seem to stop, such as in the Maunder Minimum—a 70-year period from 1645 to 1715 with little or no sunspot activity. News Intern Zack Savitsky joins host Sarah Crespi to discuss a nearby star that appears to have entered a similar quiet period, and what we can learn from it about...
