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.

They Moved Mountains (And People) To Build L.A.’s Freeways

They Moved Mountains (And People) To Build L.A.’s Freeways

Carmageddon—it was the nightmare scenario L.A.’s transportation authorities warned of when a construction project shut down a critical stretch of freeway for an entire weekend in July 2011. Gridlock. The glow of brake lights. The overwhelming angst of a city denied its full and unimpeded access to its freeways. In the end, the public outreach built around that ominous term worked. Motorists stayed home, and life went on as normal. A few wags even staged a "dinner party" on the deserted freeway.

How a Mass Whale Graveyard Ended Up Beneath a South American Highway

How a Mass Whale Graveyard Ended Up Beneath a South American Highway

Connecting Alaska to Argentina, the Pan-American Highway runs some 30,000 miles 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.

I stumbled on this photo while writing last night’s post about the East Side Access Project in New York and just couldn’t resist: like some underground rail gun or a particle accelerator whirring to life, this is part of the Second Avenue Subway, the so-called "86th Street Cavern," a subterranean wonder that will soon be indistinguishable from mere infrastructure, captured by MTA photographer Rehema Trimiew.
