Philanthropy disruptor Sara Lomelin thinks communities can build power through collective giving and the model of "giving circles": groups of people with shared values who come together to make change, strengthen their social fabric and...

Dark Energy is what we call the mysterious force that seems to be pushing the universe apart. By some calculations, it makes up 70% of everything in nature. Or...maybe it doesn’t exist at all! Plus, Juno’s observations give us new...

We live in an unusual age - the age when the stars still shine. We should count ourselves lucky - nearly all of future history will be dark. But events will still unfold in that long, cooling darkness, and civilizations may endure. So...

We only know 4% of what the universe is made up of. Can we also know what lies beyond our galaxy ... and if there are undiscovered forms of matter? Luckily, we have space messengers - cosmic rays - that bring us physical data from parts...

Animals have all kinds of adaptations to help them get through winter, from hibernation to boots and hats. But trees have to make it through the coldest months of the year alive, too, and they've developed some pretty extreme ways to do it!

David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. But -...

Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things.... a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst...

There is some super weird, noodley stuff inside neutron stars and scientists have found evidence that black holes can have strange geometries.

In this video Paul Andersen explains how the conservation of mass was replaced with the conservation of mass-energy when it was determined that they are equivalent. This famous equation not only show the mass-energy equivalence but can...

Coming to us from 50 years in the future, legendary sci-fi writer Kim Stanley Robinson tells the "history" of how humanity ended the climate crisis and restored the damage done to Earth's biosphere. A rousing vision of how we might unite...

Scientists predict climate change will displace more than 180 million people by 2100 -- a crisis of "climate migration" the world isn't ready for, says disaster recovery lawyer and Louisiana native Colette Pichon Battle. In this...

To futureproof your job against robots and AI, you should learn how to code, brush up on your math skills and crack open an engineering textbook, right? Wrong. In this surprisingly comforting talk, tech journalist Kevin Roose makes the...

The insides of the our gas giant friend, Saturn, might be less of a mystery now that we’ve figured out how to use its rings to indicate its internal makeup. And the light emitted from some very old, very hungry black holes could be...

If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which...

Minority Report science adviser and inventor John Underkoffler demos g-speak -- the real-life version of the film's eye-popping, tai chi-meets-cyberspace computer interface. Is this how tomorrow's computers will be controlled?

Scientists can’t directly observe dark matter, and they still don’t know what it is… so why are they so confident it exists?

On this Space Time Journal Club we look at how gravitational waves can be used to search for extra dimensions of space!

What exactly are the invisible things out there, and how did they help form the universe as we know it? To explore and understand the most spectacular structures out there, scientists have been using cosmic shear to indirectly detect...

It's moments after the Big Bang and you're still reeling. You're a particle of matter, amidst a chaotic stew of forces, fusion, and annihilation. If you're lucky and avoid being destroyed by antimatter, you'll be the seed of a future...

Vera Rubin graphed the rotation curves of galaxies, helping astronomers better understand the accelerated orbits of stars on the outskirts of galaxies. Her life's work generated some of the first solid evidence for dark matter in the...

Seemingly pointless scientific research can lead to extraordinary discoveries, says physicist Suzie Sheehy. In a talk and tech demo, she shows how many of our modern technologies are tied to centuries-old, curiosity-driven experiments --...
