t has, almost certainly, happened to you. You have a conversation in person, you mention something specific, and minutes later, there’s an ad for it on your phone. For the past decade, most of us have come to the same conclusion: Our phones must be listening. But are they, really? I wanted to dig into the “phone listening” theory — where it came from, what the official research says, and what’s actually happening every time you load an ad on the internet. What I learned is that creepy ads are just the tip of the iceberg, powered by a system auctioning off our location, identity, and behaviors to countless companies vying for our attention… and others looking for something else.

El Celler de Can Roca is not your typical restaurant. Nestled in the outskirts of Girona, Spain, is a humble family restaurant run by three brothers.

One is World's Best Chef.
One is the World's Best Sommelier.
One is the World's Best Pastry Chef.

What happens when this trio of talented brothers come together?

Each dish is viewed from three complimentary perspectives, allowing creations never before seen in the culinary world. Having won World's Best Restaurant and 3 Michelin Stars for 17 years, El Celler de Can Roca still operates with the same humility, grace, and love that it did 40 years ago when the Roca brothers started it in the basement of their parent's restaurant.

Therapy can pose unique challenges for men, and in this video, we delve into the reasons behind this difficulty.

In this video, I recreate some of the most fascinating photographic techniques ever invented — from pinhole cameras and RGB trichrome photography to wet plate collodion — and then explore them under a scanning electron microscope.

You'll see:

How pinhole cameras really work
Why making the pinhole smaller doesn't always improve image quality
How color photographs were created using black-and-white film
What film grain actually looks like under an optical microscope
Why a scanning electron microscope initially fails to reveal silver grains
How secondary and backscattered electrons show completely different information
A wet plate collodion selfie made from scratch
And finally... what a 19th-century photograph looks like at the micrometer scale.

Photography has changed dramatically over the last 170 years.
The chemistry hasn't.

This video traces the evolution of precision rotary motion, from brute-force turning shafts to angle encoders that resolve a fraction of an arc second.

Ozempic and similar medications are highly in-demand and yet remain deeply controversial. Online conversations about them are often full of misinformation and echo decades of flawed teachings on weight management. So what do we get wrong when we talk about this new wave of weight-loss medications? A lot, it turns out.

We went to Zermatt to experience the highest viewing platform and border crossing in Europe, operating at nearly 3,900 meters above sea level. The Matterhorn Alpine Crossing connects Switzerland directly to Italy over a glacier, and we wanted to see what it takes to build a $150 million project in these extreme conditions.

To secure the foundation, crews had to dig 25 meters down into solid permafrost. Markus took us inside the facility to show us the mechanics keeping this massive cable car moving. He explained the exact safety and backup procedures that activate if the grid fails while cabins are suspended 170 meters in the air over the Alps.

Mark Young has been living a self-sufficient lifestyle on a remote off-grid island in British Columbia for the past 21 years. He has built 9 experimental bu...

This video explores the surprising story behind one of the oldest and cheapest building materials on Earth. Thousands of years ago people built homes using simple adobe bricks made from clay sand and straw. Some of these houses are still standing today lasting longer than many modern buildings while costing only a few hundred dollars in materials. Even more incredible these thick earthen walls naturally regulate temperature keeping homes cool in summer and warm in winter without heating or air conditioning.

But if adobe works so well why is it difficult or even illegal to build this way in most places today. In this video you will discover the history of how building codes industry interests and financial systems slowly pushed natural construction methods out of the mainstream. The story reveals how a material that once housed entire civilizations became almost impossible to use in modern construction even though the science behind it is simple and proven.

You will also learn how thermal mass works and why thick earthen walls can store heat during the day and release it at night creating a natural temperature balance inside the home. Studies comparing adobe structures with conventional houses show that these buildings can maintain comfortable indoor temperatures with far less energy. In many climates they can even eliminate the need for mechanical cooling entirely.

The video also explores the people who tried to bring this ancient knowledge back. Architects engineers and builders around the world have demonstrated that earth construction can provide durable affordable housing using materials that already exist beneath our feet. Their work challenges the modern assumption that building a home must require massive loans expensive materials and complex technology.

Finally you will discover the remarkable story of a woman in Texas who found a legal loophole and used it to help hundreds of families build their own adobe homes. These homes cost a fraction of conventional houses require almost no energy to heat or cool and allow families to live without mortgages or energy bills. Her work proves that the knowledge has never disappeared and that people can still build strong comfortable homes using techniques that humanity has known for thousands of years.
