Is Pain Made in the Brain?
In your hands, you have separate sensors for heat, cold, and pain. Here's what happens when you touch something hot and cold at the same time.
Your Memories Are Not as True as You Think
Did your memories ever really happen? Turns out, every time you recall a memory, it gets a little more false. Scientists explain why your memories change over time—and why they’re less real than you think.
How Your Brain Interprets Color
Remember the infamous debate about “the dress”? Whether you saw it as blue/black or white/gold, it all comes down to the way your brain perceives color. A vision scientist explains.
Your Brain: Perception Deception Preview
Is what you see real? Join neuroscientist Heather Berlin on a quest to understand how your brain shapes your reality, and why you can’t always trust what you perceive. Learn the surprising tricks and shortcuts the brain takes to help us survive.
Could Whale Poop Help Cool the Planet?
Whales are massive reservoirs of carbon and they are key to the health of our oceans. But there are fewer whales — and less whale poop — in the ocean today than before industrial whaling took off.
How an Underwater Volcano Produced a 60-Foot Tsunami
On January 15, 2022, an underwater volcano erupted off the shores of the Pacific islands of Tonga—the most explosive event ever recorded on Earth. The blast triggered a massive tsunami with waves over 60 feet high. Here's how it happened.
Scientists Make Rare Discovery in Active Volcano
The volcano that produced one the most powerful eruptions in history has a twin, and it’s more active than scientists thought.
Witnesses Recount Surviving a Volcanic Explosion
At 5:15pm on January 15, 2022, satellites recorded the volcano Hunga Tonga-Hunga Ha’apai blast a cloud of ash and rocks into the atmosphere. Within minutes, tsunami waves crashed into the South Pacific nation of Tonga. These are the stories of some of the survivors.
Hidden Volcano Abyss Preview
In January 2022, one of the most powerful volcanic eruptions in recorded history rocked the islands of Tonga. Join scientists as they investigate what caused the blast, how it spurred a devastating tsunami, and if another eruption could be imminent.
Scientists Attempt To Free Entangled Right Whale
Endangered right whale populations are declining and not a single adult is known to have died of natural causes in more than a decade.
Meet Snow Cone the Right Whale and Her Calf
In 2020, the number of North Atlantic right whale calves born in the Southeast was slightly higher than it had been in previous years, but still nowhere near enough to get the population moving in a positive direction.
Saving the Right Whale Preview
The North Atlantic right whale is on the brink of extinction. But a handful of specialists are determined to help save it as they discover new secrets about the lives of these giants of the sea.
Why Induction Stoves Are Better for You and the Environment
These stoves use electricity to create a magnetic field that causes the electrons inside pots and pans that contain iron to vibrate tens of thousands of times. This creates the friction and heat needed for cooking without the energy or fumes from gas stoves.
How Heat Pumps Can Help Cities Lower Carbon Emissions
Heat pumps are a key solution to help reduce carbon emissions. Instead of creating heat, they move heat from one place to another and have a much lower carbon footprint. But can we make them accessible to all?
Chasing Carbon Zero Sneak Peek
Follow scientists and engineers as they explore different solutions for lowering our carbon emissions: from switching to induction stoves for cooking to making heat pumps accessible.
Chasing Carbon Zero Preview
Can the U.S. reach net-zero carbon emissions by 2050 and avoid the biggest impacts of climate change? Experts say it can be done. Here’s the technology that could get us there.
This Fungus Is Spreading Rapidly in Hospitals
Most fungi can’t grow and reproduce in the human body because it’s too warm. But experts say they’re evolving.
Hurricanes Are Getting More Destructive
For 100-million Americans living in coastal communities, more destructive storms are an increasing worry. Some are starting to confront the possibility of losing their land entirely.
How Coating Roads Could Help Beat the Heat
Concrete and asphalt make cities hotter, because they absorb the sun’s energy and re-radiate it as heat, even well into the night.
How Sewage Becomes Drinking Water
Ongoing droughts are straining the supply of clean drinking water. One solution might lie in an unexpected source: wastewater. Through a method of purification called reverse osmosis, Orange County is making millions of gallons of dirty water drinkable again.
