Life on Earth has weathered boiling-hot oceans and volcanic-ash-darkened skies—but that’s nothing like the climate change we’re experiencing now. In this episode of Crash Course Biology, we’ll talk about the greenhouse effect, learn why...

Community ecology is the study of interactions between different species of living things, and lets ecologists examine the effects of predator-prey relationships, parasites, and mutually beneficial interactions. In this episode of Crash...

Ecology is the study of the interactions of living things with each other and their environment. It’s a field that not only lets us explore the interconnections between living things, but also how our environment affects us, and how we...

What if doing your chores were as easy as flipping a switch? In this talk and live demo, roboticist and founder of 1X Bernt Børnich introduces NEO, a humanoid robot designed to help you out around the house. Watch as NEO shows off its...

Look around — almost everything you see was manufactured, from baby formula to AI data centers and beyond. Yet we rarely think about how it’s all made. Factory fixer Lauren Dunford pulls back the curtain on modern manufacturing,...

In this video Paul Andersen shows how increasing ocean temperatures causes coral polyps to release their symbiotic algae. This process of coral bleaching decreases the availability of energy for the coral and may eventually lead to coral...

The world is heading toward a massive copper shortage that could derail the clean energy transition, says mining expert Jeff More. He shows how advanced sensing technology could get us back on the right track, drastically cutting down on...

How prevalent is solar power, really? According to researcher Jenny Chase, it's already displacing fossil fuels in key energy markets around the world. She explains the rise of affordable solar power and dives into how her team tracked...

Humans have been transforming seawater into potable freshwater for millennia. Today, billions of people can’t access clean drinking water, and 87 different countries are projected to be “water-scarce” by 2050. So, how can we use seawater...

In 1968, the American Heart Association made an announcement that would influence people’s diets for decades: they recommended that people avoid eating more than three eggs a week. Their reasoning was that the cholesterol packed into egg...

Industrial manufacturers spend a huge amount of energy generating heat to make everyday materials and objects, like cement, steel, and paper. And since most companies use fossil fuels to reach these high temperatures, industrial heat...

Most living things on Earth need oxygen to survive, but scientists discovered a species of bacteria that uses oxygen totally differently from every other organism on Earth.

The Olympics inspire dreams by showcasing athletes' dedication and passion while reminding viewers of the hard work, struggles, and triumphs behind the scenes. Beyond athletics, the Games highlight global diversity, humanizing stories...

An upcoming project deadline, a fight with a family member, or even an embarrassing moment can easily trigger our body’s stress response. While we can’t always control what life throws at us, there are ways to better prepare for...

From its life-sustaining energy to its explosive geomagnetic storms, the Sun has many mysteries, says astrophysicist Nour E. Rawafi. He sheds light on NASA's latest endeavor to better understand our fiery neighbor and its impact on the...

Lily Yeh calls herself a barefoot artist: she travels the world with a suitcase full of art supplies, working with whoever wants to join her. In an inspiring talk, she shares the fruits of her collaborative art projects that bring color,...

Is it possible to meet the world's seemingly infinite demand for data storage while also caring for the natural environment? Biomedical researcher Keolu Fox and professional surfer and scientist Cliff Kapono believe that Indigenous...

The answer to this question has everything to do with drag & kinetic energy vs momentum change (thrust) ie, a bigger engine fan allows for a larger air mass to be accelerated a smaller amount to give the same thrust as you'd get from a...

How is the chemical energy of gasoline transformed into kinetic energy of a moving car? And where does that kinetic energy go when the car crashes into something and stops moving?

Which is the most intense Olympic throwing event? Shot put? Hammer? Discus? Javelin?

Where does all the stuff in the universe come from?
