Less than two percent of the Hiroshima bomb's uranium actually detonated

Little Boy, the nuclear bomb that U.S. forces dropped on the Japanese city of Hiroshima on August 6th, 1945, leveled a two-mile radius of the city, killing an estimated 80,000 people. It was an enormous amount of destruction—and it was caused by less than two percent of the uranium carried by the bomb. » 8/20/14 1:16pm Yesterday 1:16pm

New Nanotech Sensors Could Put Bomb-Sniffing Dogs Out of a Job

TSA lines are the very definition of a "necessary evil." Everyone hates the long waits and the awkward disrobing dances as you rid yourself of all your shoes, smartphones, metal, etc. Yet, we're eternally grateful when crazy people with samurai swords don't fly coach. Now, a new breakthrough in nanotechnology could… » 7/22/14 12:31pm 7/22/14 12:31pm

Today, France Is Still Cleaning Up Hundred-Year-Old Bombs From WWI

A century ago today, the first shots of WWI were fired. It was the first modern conflict, fought with fatally efficient technology. Even today, crews must safely destroy bombs left untouched for a century. Erik Olsen traveled with one of those crews for The New York Times, bringing us a video glimpse at the delicate… » 6/28/14 3:00pm 6/28/14 3:00pm

How WWI Bombs Shattered Bedrock and Changed the Geology of France

Every once in a while, we're reminded of World War I's awful legacy: Trenches that run like gashes through the French countryside, craters in farmland, the iron harvest. These scars are even deeper than we might imagine. Bombs actually shattered bedrock and created the bizarre, dimpled landscape of modern day Verdun. » 6/13/14 4:40pm 6/13/14 4:40pm

America's Tactical Nukes Are Worth Twice Their Weight in Gold

The GBU-57A-B is by far America's biggest bunker buster, but it's not actually our most powerful one. That acclaim goes to the deep diving, hard hitting, supersonic B-61 tactical nuclear bomb. And we're about to spend more than $11 billion to ensure they stay on the front lines through the middle of the next decade. » 4/25/14 11:40am 4/25/14 11:40am

The Weirdest Thing on the Internet Tonight: Monsieur Cok

Allegories abound in this macabre tale of runaway industrialism in post-World War Europe. An enterprising defense contractor replaces his inefficient human workforce with mechanical monstrosities, a move that doesn't sit well with his former employees. Returning with the hammer and sickle of socialist justice, one… » 2/27/14 12:00am 2/27/14 12:00am

Incredibly clear footage shows the blast effect of 1953 atomic bomb

In the video below, you can see cars, jeeps, buses and tanks against the backdrop of the ginormous blast's initial burst and… » 2/26/14 9:44pm 2/26/14 9:44pm

Holy crap, this train derailment created a massive freaking explosion

Oh my. This is beyond scary. A mile-long train carrying crude oil derailed near a small town in North Dakota and sent explosions, flames and dark black smoke into the sky. Luckily (and almost unbelievably), no one was hurt in the accident that looked a lot more like a nuke exploding than a train derailment. Thank god. » 12/30/13 10:41pm 12/30/13 10:41pm

Guy Builds a Bomb Just With Stuff You Can Buy After Airport Security

Just in case you were still being fooled into thinking that the TSA is good for, well, anything, follow along with You Tube contributor Terminal Cornucopia as he constructs a home-made "FRAGGuccino" from stuff you can buy from airport terminal kiosks—you know the ones you can enter after passing through security. » 11/15/13 4:53pm 11/15/13 4:53pm

How Dogs Become Awesome Bomb Sniffing Dogs

Because my imagination is trapped within the confines of my human pea brain, I always giggle to myself when I see dogs sniff anything and everything they run into. But dogs have 50 times more olfactory cells than we do! Of course they would put it to good use. And of course our human pea brains would put a dog's nose… » 7/09/13 10:00pm 7/09/13 10:00pm

The Most Terrifying Cherry Blossom to Ever Take Flight

By 1945 Allied forces were knocking on Japan's front door. As the Empire's military grew increasingly desperate, it began to focus on eliminating the Allies' willingness to fight—by intentionally crashing manned aircraft in kamikaze attacks. And for pilots aboard one breed of these notorious flying coffin, the MXY-7… » 6/05/13 11:30am 6/05/13 11:30am
