At least twenty people are dead following an explosion in Bangkok, "reports the BBC—but footage from the scene already offers a suspect.
Videos taken by nearby CCTV and tourists show how the blast hit a crowded shrine in Thailand's largest city.
Police are now hunting the yellow-shirted man seen dumping a backpack at the site of the blast.
In the new footage, he is shown carefully and deliberately removing his backpack inside the shrine, getting up without it and immediately leaving the scene.
The spot where he was sitting is precisely where the bomb went off a few minutes later, says the BBC's Jonathan Head in Bangkok.
"There is a suspect... we are looking for this guy," Prime Minister Prayuth Chan-ocha told reporters.
Authorities were "quite close" to identifying the suspect, Thai government spokesman Maj Gen Weerachon Sukhontapatipak told the BBC, but other leads were also being pursued.
I've seen this video described as a musical depiction of all the nuclear bombs ever detonated. But that sort of makes it sound like you're about to get a particularly bombastic version of the 1812 Overture. Instead, "1945-1998" by Isao Hashimoto is more like an infographic with sound effects — or, possibly, a mash-up of the games Simon and Global Thermonuclear War.
What you get is an interesting depiction of nuclear tests through time — 2053 of them (including the non-test explosions at Hiroshima and Nagasaki). I found it particularly interesting to watch the slow ramp up over the course of the late 1940s and early 1950s, when months or years would tick by between tests. After that, beginning in the late 1950s, you see these patterns of sudden flurries of explosions, usually happening in the US and the USSR almost simultaneously. The cultural sense of panic is almost palpable.
At the New Yorker, Paige Williams visits forensic chemist Adam B. Hall to talk about the surprising things you can learn about bombs and their makers by looking at the effects they produce
— from the type and color of the smoke, to the smell that lingers in the air, to what the "boom" sounds like. I'd take Hall's speculation about the Boston Marathon bombings with a grain of salt (he's making his judgements from low-grade video and isn't part of the investigation), but the process he describes is absolutely fascinating.
At Scientific American, Larry Greenemeier has a piece about the science behind the three (possibly four) improvised explosive devices that killed at least three people yesterday in Boston
. It might be easy to build bombs like these, but their DIY construction techniques also leave clues that help investigators find the people responsible.
In the photo above: "Manixia Thor (left) and a member of her all women’s bomb clearance team head into the field to clear unexploded ordnance in the Lao countryside." In April, Manixia is on a speakers' tour in the US, focused on the urgent need for funding of bomb clearance and survivor assistance efforts in Laos.

Baker was a 23-kiloton nuclear weapon that was detonated underwater at Bikini Atoll in 1946. The goal was to see what would happen to Navy boats if they were in the region where a nuclear bomb went off. The boats you see in this photo were unmanned, but there were sailors relatively close by, taking these shots. There's evidence that they weren't properly protected against fallout, and later used contaminated water to drink and bathe in. (Also, as a fictional side effect, Bikini Atoll nuclear tests like Baker might have been responsible for the creation of Spongebob Squarepants.)
My Modern Met has compiled several photographs and video that give you an up-close, mind-boggling view of the explosion — including the massive column of water that shot into the mushroom cloud and the 2-mile-high tidal wave that followed.
When the feds busted the Unabomber they found a live bomb under his bed. They needed it for evidence. But they also needed it to not explode. Enter a crack team of bomb experts who were flown in to Montana to dismantle the explosives in Ted Kaczynski's backwoods cabin.
