Social media use among teens has risen alongside rates of anxiety and depression. Addressing what he calls a mental health crisis, the Surgeon General has called for warning labels on social media platforms akin to those on tobacco and alcohol. But this comes before scientific consensus has been reached that social media causes harm. We consider the evidence that social media may be eroding the mental health of Gen Z and a challenge to the claim that presents an alternative explanation for why young people are struggling. Guests: Alison – High schooler who wrote a column describing the positive and negative effects of social media Zach Rausch – Associate Research Scientist at NYU-Stern School of Business and lead researcher to Social Psychologist Jonathan Haidt for his book, “The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness” Sarah Coyne – psychologist and Sarah Coyne Associate Director of the School of Family Life at Brigham Young University Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

Have scientists discovered an alphabet in whale calls? As researchers try to decipher the series of clicks made by sperm whales, we ask whether these cetaceans might have language, and if it follows that whales are thinking animals too. Could we one day get a peek into the thoughts of a humpback whale? Meanwhile, somewhere along the long path of evolution, one species emerged with an impressive gift for gab. Are speech and language unique human superpowers? Guests: Carl Zimmer – Columnist, The New York Times, including the article, “Scientists Find an ‘Alphabet’ in Whale Songs”.

Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.” Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis?

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today. At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.

You are getting sleeeepy and open to suggestion. But is that how hypnotism works? And does it really open up a portal to the unconscious mind? Hypnotism can be an effective therapeutic tool, and some scientists suggest replacing opioids with hypnosis for pain relief. And yet, the performance aspect of hypnotism often seems at odds with the idea of it being an effective treatment. In our regular look at critical thinking, Skeptic Check, we ask what part of hypnotism is real and what is an illusion. Plus, we discuss how the swinging watch became hypnotism’s irksome trademark.

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society. We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future? Guests: Jonathan Waldman – Author of Rust: The Longest War. Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.

Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end. We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations. Guests: Anders Sandberg – Researcher at the Future of Humanity Institute at the University of Oxford Katie Mack – Assistant professor of physics at North Carolina State University, and the author of “The End of Everything, Astrophysically Speaking.” Brian Greene – Brian Greene, professor of physics and mathematics at Columbia, and author of “Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe” Originally aired May 3, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too. Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact. Guests: Thomas Carr - Vertebrate paleontologist and Professor of Biology, Carthage College Peter Makovicky - Vertebrate paleontologist and Professor of paleontology in the Department of Earth and Environmental Sciences at the University of Minnesota David Randall - Author of “The Monster’s Bones: The Discovery of T Rex and How It Shook Our World” Steve Brusatte - Personal Chair of Paleontology and Evolution, University of Edinburgh.

Owls are both the most accessible and elusive of birds. Every child can recognize one, but you’ll be lucky to spot an owl in a tree, even if you’re looking straight at it. Besides their camouflage and silent flight, these mostly nocturnal birds, with their amazing vision and hearing, are most at home in the dead of night, a time humans find alien and scary. Ecologist Carl Safina got to know an injured baby screech owl well. Their relationship saved the owl’s life and gave Safina insider’s wisdom about these aerial hunters of the night. Guests: Carl Safina – ecologist at Stony Brook University, head of the non-profit Safina Center, and author of “Alfie & Me: What Owls Know, What Humans Believe” Tom Damiami – natural resources interpreter, singer on Long Island, NY and leader of the Shelter Island Owl Prowl Gordy Slack – science writer, former senior editor of California Wild, the science and natural history magazine published by the California Academy of Sciences Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds. Guests: Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.

Have you ever heard worms arguing? Deep-sea scientists use hydrophones to eavesdrop on “mouth-fighting worms.” It’s one of the many ways scientists are trying to catalog the diversity of the deep oceans — estimated to be comparable to a rainforest. But the clock is ticking. While vast expanses of the deep sea are still unexplored, mining companies are ready with dredging vehicles to strip mine the seafloor, potentially destroying rare and vulnerable ecosystems. Are we willing to eradicate an alien landscape that we haven’t yet visited? Guests: Craig McClain - deep-sea and evolutionary biologist and ecologist, Executive Director of the Louisiana Universities Marine Consortium. Steve Haddock - senior scientist at the Monetary Bay Aquarium Research Institute, and co-author of a New York Times op-ed about the dangers of mining.

Brace yourself for heatwave “Lucifer.” Dangerous deadly heatwaves may soon be so common that we give them names, just like hurricanes. This is one of the dramatic consequences of just a few degrees rise in average temperatures. Also coming: Massive heat “blobs” that form in the oceans and damage marine life, and powerful windstorms called “derechos” pummeling the Midwest. Plus, are fungal pathogens adapting to hotter temperatures and breaching the 98.6 F thermal barrier that keeps them from infecting us? Guests: Kathy Baughman McLeod – director and senior vice president of the Adrienne Arsht-Rockefeller Foundation Resilience Center at The Atlantic Council Pippa Moore – Marine ecologist at Newcastle University in the U.K. Ted Derouin – Michigan farmer Jeff Dukes – Ecologist and director of Purdue Climate Change Research Center at Purdue University.

Ready to become a space emigre? For half a century, visionaries have been talking about our future off-Earth – a speculative scenario in which many of us live in space colonies. So why haven’t we built them? Will the plans of billionaire space entrepreneurs to build settlements on Mars, or orbiting habitats that would be only minutes away from Earth, revive our long-held spacefaring dreams? And is having millions of people living off-Earth a solution to our problems… or an escape from them? Guests: Marianne Dyson – Author and former NASA flight controller Emily St. John Mandel – Author, most recently of “Sea of Tranquility” John Adams – Deputy Director, Biosphere 2, University of Arizona Featuring music by Dewey Dellay and Jun Miyake *Originally aired July 25, 2022 Big Picture Science is part of the Airwave Media podcast network.

Birds and bees do it … and so do fish. In a discovery that highlights the adaptive benefits of walking, scientists have discovered fish that can walk on land. Not fin-flap their bodies, mind you, but ambulate like reptiles. And speaking of which, new research shows that T Rex, the biggest reptile of them all, wasn’t a sprinter, but could be an efficient hunter by outwalking its prey. Find out the advantage of legging it, and how human bipedalism stacks up. Not only is walking good for our bodies and brains, but not walking can change your personality and adversely affect your health. Guests: Hans Larsson – Paleontologist and biologist, and Director of the Redpath Museum at McGill University in Montréal. Shane O’Mara – Neuroscientist and professor of experimental brain research at Trinity College Dublin.
