Wikipedia News: Brazzaville ammunition magazine explosion

Brazzaville arms dump blasts. Via Wikipedia News:

On 4 March 2012, a series of blasts occurred at an army arms dump in Brazzaville, the capital of the Republic of the Congo. As of late 6 March, 246 people have been confirmed dead.  ((Rep. of Congo: 246 Dead after arms depot blasts”. NPR. 6 March 2012. Retrieved 7 March 2012))  Additional bodies were said to be “unfindable.  ((CNN Wire Staff (4 March 2012). “Ammo dump explodes in Congo, killing 100-plus”. CNN. Retrieved 4 March 2012.))   Among the dead were six Chinese workers from a Beijing Construction Engineering Group work site close to the armoury.[4] Interior Minister Raymond Mboulou said that nearby hospitals were overflowing with injuries, with many wounded lying in hallways due to lack of space.  Total injures were estimated at 1,500-2,000.   ((Louis Okamba (5 March 2012). “Republic of Congo fire threatens second arms depot; first explosion killed hundreds”. Associated Press. Retrieved 5 March 2012.))  “Tens of thousands” of people were left without shelter. (( Hinshaw, Drew (4 March 2012). “Blasts Rock Republic of Congo’s Capital”. Wall Street Journal. Retrieved 4 March 2012.)) One survivor described the event as feeling like “the apocalypse;” (( Scores dead in Congo munitions depot blasts”. Al Jazeera. 4 March 2012. Retrieved 4 March 2012. ))     others described it as “like a tsunami” or earthquake.   ((  “206 killed in Republic of Congo arms depot blasts, including dozens attending Mass”. Washington Post. Associated Press. 4 March 2012. Retrieved 4 March 2012.))

A disturbing example of why hazardous materials must be handled and stored with an abundance of caution and, if possible, away from living things.

DARPA attempts to synthesize canine nose

[singlepic=167,320,240,,left] Sharon Weinberger reports at Danger Room that DARPA is attempting to synthesize or simulate the canine nose. We understand that it certain circumstances call for miniaturization – concealment, portability and risk limitation all make dog-and-handler teams, plus their needed transportation and support, relatively unwieldy. We’re reminded of General Patton’s admonition that “A good solution applied with vigor now is better than a perfect solution applied ten minutes later.” We can have new human/canine teams ready to go in a matter of months, depending on the particular specialty (debris search, explosives search, general guard work). In addition to time spent raising and selecting canine candidates.

In the long run – a successful simulation of canine olfactory capability – would do very well at airports, and other security bottlenecks. But let’s not plan around having this capability any time soon. Let’s plan around technologies in hand. As someone who has to cop to liking Star Trek quite a lot, I still had problems every time the Enterprise

(or Voyager, etc.) crew made a big scientific or engineering breakthrough on the fly – in hours or minutes, without experimentation, getting it right the first time. Technology takes false turns, rethinking, and redesign.

Alleged German terrorists apparently unable to improvise detonation mechanisms

In Suspect Denies Ties to German Bomb Plot, Souad Mekhennet and Nicholas Kulish report in the New York Times, dated 12 October, report on the case of a young GermanT man of Turkish extraction who

Atilla Selek, a young German man with Turkish parents, stands at the heart of the investigation here into the reports of a terrorist plot that shocked this nation last month. He is in Turkey, a free man for now, though he says he is under constant surveillance.

Intelligence officials say that Mr. Selek, 22, trained at a terrorist camp in Pakistan and was part of the inner circle of plotters, including the three who were arrested last month and accused of planning what the authorities say would have been a series of deadly bombings. Mr. Selek vehemently denies the accusations.

– snip –

This stood out:

German investigators are working to build a case against the three men under arrest and seven other people they say were associates in the suspected plot, which increasingly appears to have a Turkish connection. In the German federal court in Karlsruhe last week, a 15-year-old German boy of Tunisian descent testified that he had unwittingly carried the detonators from Istanbul to Germany, a security official said, speaking on the condition of anonymity because he was discussing a closed-door hearing.

The German magazine Spiegel reported that the boy had carried a package that included a pair of shoes and that the detonators had been hidden inside the soles of the shoes, to Fritz Gelowicz, one of the men in custody and a friend of Mr. Selek in Ulm. They attended the same religious centers, the Multi-Kultur-Haus and the Islamic Information Center, both of which German authorities say were sources of extreme Islamist teaching. The Multi-Kultur-Haus was closed by state authorities in December 2005.

If accurate, this group – or “cell” – didn’t have the sophistication to manage detonation by themselves. Detonation doesn’t necessarily call for sophisticated technology:

The explosive train, also called an initiation sequence or firing train, is the sequence of charges that progresses from relatively low levels of energy to initiate the final explosive material or main charge. There are low- and high-explosive trains. Low-explosive trains are as simple as a rifle cartridge, including a primer and a propellant charge. High-explosives trains can be more complex, either two-step (e.g., detonator and dynamite) or three-step (e.g., detonator, booster of primary explosive, and main charge of secondary explosive). Detonators are often made from tetryl and fulminates.  Source .

It’s not, in my view, bad news.

Land mine detection via plants – from GoodMagazine.com

GoodMagazine reports that that Denmark-based ARESA has conducted successful field tests with its genetically modified Thale Cress, for use in land mine detection.

Thale Cress, also known as Arabidopsis thaliana, commonly called arabidopsis, or mouse-ear cress, has a short life cycle – six weeks from germination to mature seed.The ARESA modified Thale Cress is very sensitive to nitrogen, which is a component of the explosives in land mines, and emitted in tiny amounts.

The Thale Cress

has been genetically modified to provide a natural warning in the presence of land mines. Thales cress is inherently sensitive to nitrogen dioxide, a chemical byproduct of land mines. The Copenhagen-based biotech company Aresa tweaked the weed’s genes so that its leaves would turn from their natural green to bright red in the presence of latent explosives. Field tests have thus far been successful, meaning traditional methods of human and canine mine detection may soon have a less dangerous alternative.

From Ben Jervey’s post in Good Magazine .While there are good reasons to have reservations about the genetic modification of plants, until and unless the powers that have been responsible for placing land mines start removing them, this seems an excellent technology.
