How Does Imagination Work? 07.10.2022

Every second of every day, whether we’re actively aware of it or not, we’re using our imagination: from what we might have for dinner to life on other worlds. But how can our brains conjure up stuff that we are not looking at or even images of things that don’t exist? Our host Dr Alfredo Carpineti is joined by cognitive scientist Professor Tyler Marghetis from the University of California, Merced...

Why Is The Universe Made Of Matter And Not Antimatter? 23.09.2022

Everything we see, from galaxies to capybaras, is made of matter. But matter has a mirrored version of itself known as antimatter. If the two come into contact they annihilate one another, turning into pure energy. Why does the universe prefer one over the other? This is a fundamental mystery of the universe, and at the forefront of the search for an answer is the  Alpha Experiment  at CERN. In th...

How Do We Know When A Species Is Extinct? 09.09.2022

It’s no secret that species extinction and biodiversity loss are making our environment increasingly less stable. As it feels like we inch closer to waving goodbye to threatened animals like the Javan rhino, a question springs to mind: How do we know when a species is extinct? How, for instance, do we know there aren’t some animals left just hiding in a bush somewhere? In this episode, host Rachae...

Can Humans Live Forever? 26.08.2022

We live in a society that idolizes youth for sure, but also with age comes wisdom. However, aging is not all it’s cracked up to be. Could we keep getting older without the drawbacks of being old? Other animals do it, so maybe one day it could apply to humans too. In this episode, host Dr Alfredo Carpineti is joined by Dr Andrew Steele, author of Ageless: The New Science of Getting Older Without Ge...

Is The Future Of Farming Underwater? 12.08.2022

As the human population increases so too does our demand for food, but in the face of the climate crisis scientists are seeking alternative and sustainable solutions to traditional agricultural practices. In this episode of IFLScience, The Big Questions, we teamed up with BBC Earth to speak with Luca Gamberini of Nemo’s Garden to ask: Is the future of farming underwater? Nemo’s Garden is working t...

How Will The Universe End? 29.07.2022

Studying the Universe told us the cosmos began with the Big Bang. But how will everything end? In a cold and desolate nothingness? Or will everything collapse back into itself in a Big Crunch? In this episode, host Dr Alfredo Carpineti is joined by theoretical astrophysicist Dr Katie Mack, the Hawking Chair in Cosmology and Science Communication at the Perimeter Institute, who has written extensiv...

What Is The Universe Made Of? 28.10.2021

Everything we see and interact with, regular matter, is only a small fraction of what the universe contains. In fact, the vast majority of the universe is invisible to us. We've named these mysterious components dark matter and dark energy, but our understanding of them – and if they even exist – remains lacking. To unravel more of this mystery, Dr Alfredo Carpineti sat down with Dr Mandeep Gill f...

Can We Achieve Unlimited Energy? 14.10.2021

Humanity's ever-growing need for energy has led to a world that is dramatically changing, ravaged by extreme weather events. The way we get power has to change. Our question in this episode is about a potential new approach. Can we master nuclear fusion and achieve unlimited energy? Our host Dr Alfredo Carpineti talks to Dr Elise Delchambre of the International Thermonuclear Experimental Reactor (...

What Is Consciousness? 30.09.2021

Of all the mysteries of the universe, none is closer to us as human beings than this one: what is consciousness? How does our brain turn electrical signals into thoughts and feelings? In this episode, host Dr Alfredo Carpineti and Professor Liad Mudrik from the School of Psychological Sciences And Sagol School of Neuroscience at Tel Aviv University discuss these questions and more as they try and...

Can We Stop Or Reverse Climate Change? 16.09.2021

The climate crisis is unfolding around us with extreme weather events becoming more common and living organisms having to survive or perish in a changing world. In this episode, host Dr Alfredo Carpineti sat down with Dr Alexandre Kōberle, a research fellow at the Grantham Institute for Climate Change, to discuss how we got here, how we can avoid the worse case scenarios, what political will is ne...

Are We Alone In The Universe? 02.09.2021

From extraterrestrial intelligence to simple life forms, the Universe might be teeming with life. Can we find and communicate with these life forms? IFLScience spoke to Dr Seth Shostak, Senior Astronomer at the SETI Institute to tackle the fundamental question: are we alone in the Universe?
