Cement is one of the most-consumed materials on Earth — second only to water — and it accounts for a whopping eight percent of the world's carbon pollution. What if we could turn this climate villain into a hero? Clean tech innovator and...

Concrete doesn't dry - it sets!

The world relies on manufacturing, and manufacturing relies on heat — a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a...

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Concrete is the second most-used substance on Earth (behind water), and it's responsible for eight percent of the world's carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement...

Greenhouse gases are colorless, scentless and invisible, making them exceptionally hard to measure. Fortunately, some tools and techniques can help -- one of the most powerful being artificial intelligence, says green technologist...

Throughout history humans have come up with lots of different ways to build shelters for themselves. But sometimes, inspiration for better construction materials comes from nature, in structures you might not expect — like the scales on a

The financial sector often talks of decarbonizing investment portfolios as a way to fight climate change. But portfolios can be "cleaned" without having any real impact on the problem, says investment expert Nili Gilbert. Bringing...

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Concrete is the most widely used construction material in the world. It can be found in swathes of city pavements, bridges that span vast rivers and the tallest skyscrapers on earth. But it does have a weakness: it's prone to...

Google's fun new time-waster is actually a pretty advanced piece of Artificial Intelligence. And there's some (about 43%) good news about cement's carbon footprint this week!

The Romans developed a lot of infrastructure like roads and aqueducts to both help their cities flourish and to... you know... be better at war. But the interesting thing about Roman Engineering is how it was almost all focused on Techne...

There are a lot of resources given by nature for free -- all we need is our sensitivity to see them and our creativity to use them, says architect Anna Heringer. Heringer uses low-tech materials like mud and bamboo to create structures...

Concrete doesn't dry - it sets!

Majd Mashharawi was walking through her war-torn neighborhood in Gaza when an idea flashed in her mind: What if she could take the rubble and transform it into building materials? See how she designed a brick made out of ashes that's...

A look back at some of our favorite moments from 2013 of Hank doing the messing up thing.

Engineers would love it if concrete bridges and skyscrapers didn't require so much maintenance, and they might have found the perfect solution using bacteria.

Join Squeaks for one of his favorite episodes all about RATS! You'll get to play a few rounds of true or false to learn some interesting facts about these furry creatures!

Concrete is all around us: we use it to build our roads, buildings, bridges and much more. Yet over the last 2,000 years, the art of mixing cement and using it to bind concrete hasn't changed very much -- and it remains one of the...

Concrete is responsible for 8% of humanity’s carbon emissions because making its key ingredient - cement - chemically releases CO2, and because we burn fossil fuels to make it...

Concrete sucks CO2 out of the atmosphere, but making it initially produces a lot of carbon dioxide as a byproduct. Fortunately, by rethinking the chemistry of cement altogether, we can actually use carbon dioxide to create our concrete...

Today we’ll explore more about two of the three main types of materials that we use as engineers: metals and ceramics. We’ll discuss properties of metals, alloys, ceramics, clay, cement, and glass-ceramic materials. We’ll also look at...

Today roads, sidewalks, bridges, and skyscrapers are made of a material called concrete. There's three tons of it for every person on Earth. It's also played a surprisingly large role in rising global temperatures over the last century....
