In 1967, Jocelyn Bell Burnell made a discovery that revolutionized astronomy. She detected the radio signals emitted by certain dying stars called pulsars. Today, Jocelyn's story. Scientist-in-residence Regina G. Barber talks to Jocelyn about her winding career, her discovery and how pulsars continue to push the field of astronomy today. (encore)

Being small has its advantages - and some limitations. One organism that intimately knows the pros and cons of being mini is the pumpkin toadlet.

As an adult, the animal reaches merely the size of a chickpea. At that scale, the frog's inner ear is so small, it's not fully functional. That means the frog's movements seem haphazard. Today, with the help of Atlantic science writer Katie Wu, we investigate: If a frog can't jump well, is it still a frog? (encore)

Read Katie Wu's piece in The Atlantic, A Frog So Small, It Could Not Frog.

Does your mum’s singing make you cringe with embarrassment? Do your dad’s jokes make you want to scream - and not with laughter? Or maybe you are the parent driving your offspring round the bend with rules and curfews?

If so, you are not alone. CrowdScience listener Ilixo, age 11, has been wondering why it is that our parents become so annoying as we become teenagers. Is it something that is changing in his brain or are they actually becoming more annoying as they age? Presenter Marnie Chesterton consults our assembled panel of experts to discuss conflict between parents and their offspring.

Developmental psychologist Liane Alampay, from the Ateneo de Manila University, Philippines, describes how the teenage experience varies around the world. Child and educational psychologist Laverne Antrobus in London says the teenage quest for independence is a normal - and necessary - developmental stage for becoming an adult. And Jennifer Lansford, a Research Professor at Duke University who studies parenting and child development, offers insights into the role peers play. Do not despair! - the panel offers tips for how to keep the peace - whether you’re an argumentative adolescent or a provoking parent.

Kwasi Wrensford describes the subjects of his research as "elfin": skittish little squirrel-cousins with angular faces, pointy ears and narrow, furry tails. He studies two species in particular: the Alpine chipmunk and the Lodgepole chipmunk. As the climate warms, these two chipmunks have developed different ways of coping. The Alpine chipmunk has climbed higher, in search of cooler habitat, while the Lodgepole chipmunk continues to thrive in its historic habitat. On this episode, Kwasi explains to Emily Kwong how these squirrelly critters typify two important evolutionary strategies, and why they could shed light on what's in store for other creatures all over the globe.

This week, the UN Biodiversity Conference (COP 15) wrapped up in Montreal, Canada. Nations from around the world came together to establish a new set of goals to help preserve the planet's biodiversity and reduce the rate of loss of natural habitats. The last time biodiversity targets were set was in 2010, at COP 10. In the 12 years since, the world collectively failed to meet any of those biodiversity benchmarks.

Aaron Scott talks to Giuliana Viglione, an editor at Carbon Brief covering food, land and nature. She shares what she saw on the ground at COP 15, what the new goals for 2030 are, and why she has more hope that progress will be made this time around.

Psychedelic drugs – like LSD, salvia, ayahuasca, Ibogaine, MDMA (AKA ecstasy), or psilocybin (AKA 'magic mushrooms' or 'shrooms') – are experiencing a resurgence of interest in their potential medical benefits.

At the Neuroscience 2022 meeting held by the Society of Neuroscience, the appetite for psychedelic research permeated the sessions, discussions, and even after-hours barroom talk — drawing in researchers, neuroscientists, companies, reporters, and advocates alike.

"In the last couple of years there has been a lot of excitement in psychedelics. I think it started first in the popular media." says Alex Kwan, associate professor at Cornell University. "Neuroscience, actually, I think took another year or two to catch on."

Today on the show, host Aaron Scott and NPR's brain correspondent Jon Hamilton chat psychedelic drugs — whether this renewed interest will represent incremental or revolutionary changes in the fields of medicine, psychology, and neuroscience.
