Scientists Make Bricks With Sludge Filtered From Arsenic-Laced Water

Arsenic-contaminated water is a massive problem in the developing world. But, even when you filter it out, the toxic sludge that the process produces often gets dumped right back into the water supply.

How A Mass Whale Graveyard Ended Up Beneath A Highway

Connecting Alaska to Argentina, the Pan-American Highway runs some 48,000km north to south. Construction to widen the highway briefly stopped, however, to make way for dead whales back in 2010, when workers digging through a remote stretch of the Chilean desert found a huge trove of bones millions of years old. Now, scientists think they have figured out how the extinct whales ended up on land in the first place.

Breaking The Record For The Largest Concrete Pour In The World

New skyscrapers will do anything for attention — which is why an under-construction supertall in Los Angeles, soon to be the tallest building on the West Coast, is trying to break another record too. Starting Saturday, construction crews will pump 16,000 cubic metres of concrete onto the Wilshire Grand site, which might make it the largest continuous foundation pour in the world.

The Concrete Blocks At This Bakery Are Made From Empty Sacks Of Flour

From afar, the walls at this Gowanus restaurant look like they’re made from grey fabric — but they’re actually made from concrete bricks poured into empty bags of flour from the resident bakery. Concrete masonry unit? More like cookie masonry unit! Sorry.

Sochi's Olympic Village Is Half-Built And Full Of Trash

Sochi’s in bad shape. With two weeks to go before the most expensive Olympic Games ever, the sleepy city on the Black Sea sort of looks like a giant garbage dump. All it needs now is a giant torch to start a giant tire fire.
