Bottlenose dolphins working for the U.S. Navy discovered a rare 19th century torpedo off the coast of Coronado, Calif., while searching for underwater mines and other objects that evade technological detection. The brass torpedo is 11 feet long and weighs 132 pounds, and it could range 400 yards when launched. Called a Howell torpedo, the old military relic was a marvel in its day, the Los Angeles Times reports, and will likely find a home in a military museum.

While not as well known as the Gatling gun and the Sherman tank, the Howell torpedo was hailed as a breakthrough when the U.S. was in heavy competition for dominance on the high seas. It was the first torpedo that could truly follow a track without leaving a wake and then smash a target, according to Navy officials.

Only 50 were made between 1870 and 1889 by a Rhode Island company before a rival copied and surpassed the Howell’s capability.

Until recently only one Howell torpedo was known to exist, on display at the Naval Undersea Museum in Keyport, Wash. Now a second has been discovered, not far from the Hotel del Coronado.

The dolphins that uncovered the long-lost treasure use a biosonar system more sophisticated than any modern technology can provide. When dolphins find an object of interest, they resurface and tap the front of their handlers’ boat with their snouts. Last month, a dolphin named Ten indicated something was submerged in the area where the torpedo was later discovered, though at the time its human handlers dismissed the signal since they didn’t expect to find any objects there. Last week, another dolphin named Spetz alerted its handlers to the same spot, and this time the humans paid attention.

Navy divers and then explosive-ordnance technicians examined the object, which was in two pieces, and determined that the years had rendered it inert. On one piece was the stamp “USN No. 24.”

The torpedo pieces were lifted to the surface and taken to a Navy base for cleaning and to await shipment to the Naval History and Heritage Command, located at the Washington Navy Yard.

According the the LA Times, the divers had to consult both Google and military experts to reveal the identity of the ancient torpedo.

In Croatia, scientists are working on a new way to detect land mines without risking lives, reports the Associated Press. Honeybees, the scientists say, have an incredible sense of smell, and with the right amount of prodding can be trained to sniff out TNT, the most common explosive used in land mines. In preliminary testing:

Several feeding points were set up on the ground around the tent, but only a few have TNT particles in them. The method of training the bees by authenticating the scent of explosives with the food they eat appears to work: bees gather mainly at the pots containing a sugar solution mixed with TNT, and not the ones that have a different smell.

A common technique in animal behavior training, the bees are taught to associate the smell of TNT with food. Once that association is firm, the bees can be turned loose in search of mines.

”It is not a problem for a bee to learn the smell of an explosive, which it can then search,” Kezic said. “You can train a bee, but training their colony of thousands becomes a problem.”

Bees, with their incredible sense of smell, light weight and ability to fly should be better candidates for mine hunting than other approaches. Mine decommissioning teams already use dogs and rats to hunt down mines. But, some anti-personnel mines are so sensitive that the weight of a pup can set them off. The bees’ training is still underway, says the AP, but if and when they’re ready the Croatian-trained bees will be able to flit from mine to mine without setting them off.

From 1999 to 2008, says the Guardian, 73,576 people reportedly died to hidden land mines or unexploded munitions. “Of these, around 18,000 were confirmed deaths – 71% of victims were civilians and 32% were children.” Aside from their destructive potential, land mines are also a psychological and social plight.

Landmines and cluster munitions have been described as “weapons of social cataclysm”, which perpetuate poverty and prevent development. They leave a legacy of indiscriminate civilian injuries and deaths, burden struggling healthcare systems and render vast tracts of land uninhabitable and unproductive. As Kate Wiggans, from the International Campaign to Ban Landmines and Cluster Munition Coalition (ICBL-CMC) says: “They keep poor people poor, decades after conflict.”

The U.S. military has a non-lethal toy straight out of dystopian science fiction. It is, literally, a pain gun. Known as “Active Denial Technology,” the pain gun shoots extremely high frequency microwaves from a truck hundreds of meters away. When these waves hit your skin, you feel like you’re being cooked alive. Last year, Wired‘s Spencer Ackerman volunteered to get shot by the non-lethal weapon:

When the signal goes out over radio to shoot me, there’s no warning — no flash, no smell, no sound, no round. Suddenly my chest and neck feel like they’ve been exposed to a blast furnace, with a sting thrown in for good measure. I’m getting blasted with 12 joules of energy per square centimeter, in a fairly concentrated blast diameter. I last maybe two seconds of curiosity before my body takes the controls and yanks me out of the way of the beam.

Here’s what it looks like to get shot, as experienced by Ackerman:

Former Navy SEAL Richard Machowicz took a turn, too, for his Discovery Channel show Future Weapons. He didn’t like it much, either.

The Active Denial pain ray is big and scary, sure. But it’s also mounted on a huge expensive truck, and thus, unlike tasers or rubber bullets, is not a thing you’ll likely see in real life right now. But that may soon change. According to New Scientist, Raytheon, the defense contractor behind the pain gun, is working on a portable version:

Raytheon is now building smaller versions for law enforcement or commercial maritime use – designed to be placed inside buildings, such as prisons, or mounted on ships for defence against, say, pirates. And soon there could be handheld versions of the pain ray. Raytheon has developed small experimental prototypes, one of which is about the size of a heavy rifle and is intended for police use.

As a non-lethal weapon, the pain ray is actually incredibly effective. The weapon causes a burning sensation so strong that it triggers “reflexive ‘repel’ reactions.” People just want to get out of the way. And, from the testing done so far, the pain gun has a low chance of doing any real damage. So far, 11,000 people have been shot, and only eight of them got burned. But these were all under proper testing conditions, not out in the field in the middle of a riot.

But as a non-lethal weapon, the pain gun has something rubber bullets and tasers and tear gas do not: it is invisible—people being shot by it will likely have absolutely zero idea what is going on, and in most cases the gun leaves no physical wounds.

This distinction, says New Scientist, got a plan to use the portable version of the device in a California prison shut down.

On the eve of going live, the trial was cancelled. It was not over health concerns, explains Chris Tillery of the NIJ’s Office of Science and Technology… The test was shut down, he says, because of an unexpected outcry in the media and elsewhere about the potential for abuse of the technology.

And this goes to the heart of the moral dilemma raised by a technology that can induce pain invisibly. It may be medically safe if used properly, but in the wrong hands, it could also be a tool of oppression and torture.

For now, says New Scientist, the potential to use the weapon in law enforcement is under review by the National Institute of Justice.

It helps to have hard evidence when making a case against criminals. For those who committed crimes against humanity, that evidence often takes the form of mass graves. But locating hundreds or even thousands of buried bodies can be more difficult than it sounds. A team of researchers from the UK and Colombia hope to ease that search process by developing new means of sniffing out sites of atrocities.

In a poster abstract presented at the Meeting of the Americas in Mexico, the authors write:

Nowadays, there are thousands of missing people around the world that could have been tortured and killed and buried in clandestine graves. This is a huge problem for their families and governments that are responsible to warranty the human rights for everybody. These people need to be found and the related crime cases need to be resolved.

Currently, the science of detecting mass graves is hit or miss. Local governments and organizations try different methods of detecting clandestine burial sites, and some work better than others depending upon the circumstances. Developing a standard, refined technique for both locating the graves and determining factor such as the time of death, the researchers think, will expedite the process of convicting murderers for their crimes.

In the UK, researchers pursued this goal by burying pigs and then monitoring soil gases, fluids and other changes over time as the carcasses decomposed underground. Those results are already being applied throughout Europe. But bodies break down differently in different climates, and for this new project, researchers will bury pigs in eight different mass grave simulation sites throughout Colombia. Each of the site will represent a different climate, soil type and rainfall pattern. They plan to use grond penetrating radar, electrical resistivity, conductivity, magnetometry and other measures to characterize the grave sites over 18 months.

If you had to pick the toughest animal in the sea, you’d probably go for the great white shark. Or maybe the giant squid. You probably wouldn’t pick the seahorse—a delicate, awkward little creature that clings to the seafloor. But the seahorse is exactly where armor designers are looking for new insights into building robots.

This video, from UCSD’s Jacobs School of Engineering, explains:

Specifically, the engineers are looking at the tail plates on the little sea creature. Seahorses use their tails to hold on to objects like stalks and stems on the ocean floor. The plates that line their tails have to be both flexible enough to grasp and rigid enough to defend themselves from predators. Here’s the UCSD press release:

Most of the seahorse’s predators, including sea turtles, crabs and birds, capture the animals by crushing them. Engineers wanted to see if the plates in the tail act as an armor. Researchers took segments from seahorses’ tails and compressed them from different angles. They found that the tail could be compressed by nearly 50 percent of its original width before permanent damage occurred. That’s because the connective tissue between the tail’s bony plates and the tail muscles bore most of the load from the displacement. Even when the tail was compressed by as much as 60 percent, the seahorse’s spinal column was protected from permanent damage.

The researchers didn’t start with seahorses when they tried to think of armor to study. First, they looked at armadillos, alligators and other fish. But the flexibility of the seahorse tail is what was interesting to them. Here’s how that tail comes together:

Of course, this isn’t the first unlikely animal that robot and armor designers have looked at for insight. Abalone shells are in the running, too. In fact, the same lab is looking at abalone shells to figure out how they get so hard. LiveScience reports:

Abalones create a highly ordered brick-like tiled structure for their shells that is the toughest arrangement of tiles theoretically possible, says Marc A. Meyers of the University of California, San Diego (UCSD). The tiles are comprised of calcium carbonate, or chalk, sandwiches coated top and bottom with a thin protein.

They’re not limiting themselves to sea creatures, either. The lab also wants to see if toucan beaks—extremely strong but also very light—could be useful. The lab explains:

The beak’s interior is a highly organized matrix of stiff cancellous bone fibers that looks as if it was dipped into a soapy solution and dried, generating drum-like membranes that interconnect the fibers. The result is a solid “foam” of air-tight cells that gives the beak additional rigidity.

Which apparently looks a lot like a banana:

In the past few years, it’s become clear that the NFL has a problem with brain injury. Repeated, low level head trauma can cause serious long term side effects on players, and the league has committed research money to figure out how bad those side effects are and what can be done to avoid them. But for all you hear about the football players, the largest group of people dealing with traumatic head injury—soldiers—often goes unnoticed.

60 Minutes recently ran a piece about the thousands of soldiers who return home from combat with traumatic brain injuries. Many don’t even recognize what exactly they’re suffering from:

Last year, the Department of Veteran Affairs proposed new regulations to help veterans get health care and compensation for those injuries—problems like Parkinsonism, seizures, dementias, depression and hormone deficiencies. The New York Times reports:

Since 2000, more than 250,000 service members — some still on active duty — have received diagnoses of traumatic brain injury, or T.B.I., according to the Defense Department. Though T.B.I. is commonly viewed as resulting from blast exposure, the vast majority of those injuries were diagnosed in nondeployed troops who were involved in vehicle crashes, training accidents or sports injuries.

The organization American Veterans with Brain Injuries (AVBI) was founded in 2004 to address the growing numbers of veterans returning with these brain injuries. They put together this slide show to give a face to the thousands of veterans dealing with the side effects:

In the 60 Minutes piece, veterans explain why these brain injuries are so subtly terrible. One soldier told reporters, “If I could trade traumatic brain injury for a single-leg amputation I’d probably do that in a second.” The military is so used to treating visible wounds, the 60 Minutes story argues, that it forgets about the ones it can’t see. “In the military, concussion was an invisible — and therefore neglected — wound.”

Since the military wasn’t dealing with it, Arnold Fisher, a long time patron of the military, decided to create a foundation for these veterans called Make it Visible. They build health centers for veterans around the country. “People say to me the government should be doing this. Yeah, the government should be doing this, but they’re not. So we do it,” he told 60 Minutes.

How Dangerous Is Hitting Another Human Being With Your Head?

Most of us spend our time on the internet looking at cat videos and long lists of animals in different types of sweaters. But some people, like soldiers, actually use the internet for critical work—communicating with one another, controlling objects and weapons and calculating positions. As important as the internet has become to soldiers, they’re not exactly in locations where setting up an internet connection is easy, and DARPA is looking for ways to make the battlefield internet better.

Normally, soldiers use something like Mobile ad hoc networks (MANET), a way to build a network without cable lines or infrastructure. Made up of a set of nodes, the MANET structure simply sends information between individuals, rather than going through a main router like your internet does. But the number of nodes that MANET can deal with tops off at about 50, and there are often more than 50 soldiers moving about at a time.

Popular Science reports:

Citing 20 years of failure in adapting internet-based ideas task, DARPA is soliciting research paper abstracts that look elsewhere, and they’re dreaming big. A small, 50 node network is useful, but with more nodes a much larger force could benefit from increased battlefield awareness on a tremendous scale, and could do so as events unfold, rather than waiting for information sent up to headquarters to be sent back down again.

In its call for research help, DARPA frames the problem this way:

Are large scale Mobile Ad-hoc Networks (MANET) possible? If so, what problems does the industry have to solve and what software needs to be developed? DARPA’s goal is to field MANETs with 1000- 5000 nodes. But it is difficult to field a MANET with 50 nodes. Why is this? DARPA plans to host a symposium to explore this question.

What they don’t want, they say, is a tweaked version of what they already have. “It is not about redesigning or rearchitecting the Internet; there are other ongoing efforts focused here. It is not about developing protocols for use in commercial applications or in areas with well supported, ubiquitous infrastructure,” the report explains.

Now, the idea of a battlefield internet isn’t new, of course. And some argue that thinking of each soldier as a node in a network is misguided. David Axe at the Center for Public Integrity writes:

By transforming every soldier into a communications node, capable of transmitting and receiving large volumes of data from many sources, Army leaders imagined they could chart the path to an era of high-tech wars in which information was as important as bullets and shells.

But in doing so, the planners went the wrong way, according to independent analysts. Instead of repairing their communications problems with lighter, easier-to-use radios, and a simpler network, they chose heavier, more complex devices.

But DARPA says that the real issue is increasing the number of nodes. If each soldier can become a node, the issue of complexity of battle becomes less of an issue. Mark Rich, a program manager at DARPA, said, “A MANET of a thousand nodes could support an entire battalion without the need for manual network setup, management and maintenance that comes from ‘switchboard’-era communications. This could provide more troops with robust services such as real-time video imagery, enhanced situational awareness and other services that we have not yet imagined.”

The Wolfsschanze, or Wolf’s Lair, was Hitler’s bunker outside of Rastenburg, Germany. Photo: Steve

Margot Woelk, now 95, is the last surviving member of a team tasked with keeping Hitler alive as he hunkered down in the Wolf’s Lair in the final chapters of World War II. For nearly all her life, says the Associated Press, Woelk kept quiet about her wartime activities. But now, in her old age, she wants to talk, and her stories are filled with details of life in Hitler’s fortress and about living a life of “constant fear.”

Woelk was the sole survivor of the Nazi leader’s poison paranoia. In her mid-20s, she was swept away from her home in Ratensburg (now Ketrzyn, Poland), “drafted into civilian service” to join 14 other women in the dictator’s wartime bunker where she and the others were charged with taste-testing the leader’s meals.

As the war dragged on, food supplies in much of German-occupied territory suffered. Within the Wolf’s Lair, however, “the food was delicious, only the best vegetables, asparagus, bell peppers, everything you can imagine. And always with a side of rice or pasta,” said Woelk.

“He was a vegetarian. He never ate any meat during the entire time I was there,” Woelk said of the Nazi leader. “And Hitler was so paranoid that the British would poison him — that’s why he had 15 girls taste the food before he ate it himself.”

But each meal brought fear, says Woelk. “We knew of all those poisoning rumors and could never enjoy the food. Every day we feared it was going to be our last meal.”

Nearing the end of the war, after tensions mounted following an unsuccessful attempt on Hitler’s life from within the bunker, Woelk fled. When Soviet troops took the Wolf’s Lair a year later, the other taste testers were all shot. But the end of the war was not the end of Woelk’s ordeal, according to the AP. She suffered abuse at the hands of Russian troops long after the war ended, she says:

“For decades, I tried to shake off those memories,” she said. “But they always came back to haunt me at night.”

…Only now in the sunset of her life has she been willing to relate her experiences, which she had buried because of shame and the fear of prosecution for having worked with the Nazis, although she insists she was never a party member.

In a letter to Congress, writes the Guardian, the White House stated that officials believe, with “varying amounts of confidence,” that the chemical weapon sarin was used in the ongoing conflict in Syria and that the use of this type of weapon “would very likely have originated with” supporters of Bashar al-Assad and the Syrian government. The link between the use of sarin and al-Assad is not completely firm, though, and the U.S. Intelligence community is looking for more proof of what’s really going on.

Sarin, wrote Smart News previously, is a nerve agent first developed in 1938 Germany. “A colourless, odourless gas with a lethal dose of just 0.5 mg for an adult human,” sarin, “can be spread as a gaseous vapor, or used to contaminate food. The CDC says that symptoms can arise within seconds, and can include, like VX, convulsions, loss of consciousness, paralysis, and death.” And according to a 2002 article from the New York Times, sarin “dissipates to nondeadly levels after a few hours.”

How exactly are investigators supposed to figure out what’s going on in Syria? According to the Guardian, the United Nations will carry out analyses of soil samples collected in Syria to try to figure out if sarin gas was used. But, says Wired‘s Danger Room, there is another way to check for sarin.

The U.S. military tests for evidence of nerve gas exposure by looking for the presence of the enzyme cholinesterase in red blood cells and in plasma. (Sarin messes with the enzyme, which in turn allows a key neurotransmitter to build up in the body, causing rather awful muscle spasms.) The less cholinesterase they find, they more likely there was a nerve gas hit.

The problem is, some pesticides will also depress cholinesterase. So the military employs a second test. When sarin binds to cholinesterase it loses a fluoride. The pesticides don’t do this. This other test exposes a blood sample to fluoride ions, which reconstitutes sarin if it’s there, in which case it can be detected with mass spectrometry.

Blood samples are drawn from a pricked finger tip into a 10 milliliter tube. They can be kept fresh for about a week before they have to be used in the blood analyzer, a gizmo about the size of a scientific calculator that produces varying shades of yellow depending on the cholinesterase level.

There is still a lot of uncertainty around this news, both about what happened and what, if anything, to do about it. At least there are relatively specific tests that can be done to sort out the first question.

If Syria Uses Chemical Weapons, Here’s How They’ll Work

On Monday afternoon, four hours after the annual Boston marathon began, two bombs exploded in the area just around the finish line, killing three and injuring nearly 200 people. Four days later, one suspect in the bombing attack is dead, and, as of this writing, the city of Boston is in lockdown mode as a manhunt is underway for a second. Authorities have identified the bombing suspects as Dzhokhar and Tamerlan Tsarnaev, two brothers who moved to the area roughly a decade ago from Makhachkala, Dagestan, a region that is part of the North Caucasus that forms southwestern Russia.

The area has been a hotbed for conflict in recent decades, including terrorist bombings carried out elsewhere in Russia. Starting in 1994, following the collapse of the Soviet Union, the First Chechen War broke out. It was during this time that the Tsarnaevs would have grown up. The Council on Foreign Relations:

In the early 1990s, following the Soviet collapse, separatists in the newly formed Russian Federation Republic of Chechnya started an independence movement called the Chechen All-National Congress. Russian President Boris Yeltsin opposed Chechen independence, arguing that Chechnya was an integral part of Russia. From 1994 to 1996, Russia fought Chechen guerillas in a conflict that became known as the First Chechen War. Tens of thousands of civilians died, but Russia failed to win control of Chechnya’s mountainous terrain, giving Chechnya de facto independence. In May 1996, Yeltsin signed a ceasefire with the separatists, and they agreed on a peace treaty the following year.

But violence flared again three years later. In August 1999, Chechen militants invaded the neighboring Russian republic of Dagestan to support a local separatist movement. The following month, five bombs exploded in Russia over a ten-day period, killing almost three hundred civilians. Moscow blamed Chechen rebels for the explosions, which comprised the largest coordinated terrorist attack in Russian history. The Dagestan invasion and the Russian bombings prompted Russian forces to launch the Second Chechen War, also known as the War in the North Caucasus. In February 2000, Russia recaptured the Chechen capital of Grozny, destroying a good part of the city center in the process, reasserting direct control over Chechnya. Tens of thousands of Chechens and Russians were killed or wounded in the two wars, and hundreds of thousands of civilians were displaced.

The First Chechen War (so-called, though not actually the first) broke out in 1994, causing more than 300,000 people to flee the region as refugees. The Second Chechen War added to this emigration.

The Chechen’s (or Nokhchi in their own tongue) bid for independence, however, has stretched back hundreds of years. “The Chechens have evidently been in or near their present territory for some 6000 years and perhaps much longer,” says University of Berkeley professor Johanna Nichols. “There is fairly seamless archaeological continuity for the last 8,000 years or more in central Daghestan.”

PBS has a detailed look at the history of the region, tracing the lands change of hands from the 1400s onward, from the Mongols to the Ottoman Empire to the Russians under Ivan the Terrible in 1559.

In 1722, says PBS, “Peter the Great, ever eager for trade and military routes to Persia, invaded Chechnya’s neighbor Daghestan.”

Repulsed by the Daghestanis and Chechen mountain warriors, Russia fell back again, but would press on for the next 50 years with sporadic raids on Chechen and Daghestani territory. In 1783, Russia finally gained a strategic toehold in the Caucasus with the recognition of Georgia, Chechnya’s Christian neighbor to the south, as a Russian protectorate.

In 1784, led by Muslim leader Imam Sheik Mansur, the Chechens took back their land. This struggle went back and forth through the 19th and 20th centuries. Starting in the late 17th century, says Berkeley professor Nichols, the Chechens largely converted to the Sunni branch of Islam. “Islam is now, as it has been since the conversion, moderate but strongly held and a central component of the culture and the ethnic identity,” according to Nichols. Muslim beliefs are common throughout the region, as well as in nearby Turkey.

In 1944, in the midst of World War II, “Soviet leader Joseph Stalin ordered the Chechens and their Ingush neighbors — some 400,000 people — to be deported to Central Asia and Siberia for “mass collaboration” with invading Nazis.” Evidence to support Stalin’s charges,” however, “remains limited.”

Over the centuries, the motivations for war have varied, from invaders wanting a trading path through the mountains to religious holy wars to pure political oppression.

Georgia at a Crossroads

Guns are on the minds of Americans. We’re not sure if we should ban them, control them or give them away for free. Politicians are debating what we should do with them. Teachers are worrying how to keep them out of schools or how to train kids to respond. And architects wonder if they can design gunman-proof buildings.

On Archinect, a discussion forum for architects, Peter Normand wondered what he could do to design spaces that reduced the chances of getting shot, writing:

Assuming that a larger portion of the general public will be carrying guns, that we are in the beginning of a personal arms race, what responses should architects consider?  Do we need bullet proof doors and windows for schools, Classroom panic rooms?  How can we make the built environment safe for the gun packing and unarmed public to interact? Can we expect building codes to address the life safety issues of firearms as thoroughly as fires?

Assuming the political reality won’t change for the next decade what can we do as a designer to keep the public safe in this new gun saturated environment?

The problem of using architecture to keep safe from aggression is actually quite old. Long before guns, cities were designed to defend against attackers with weapons. Those fortresses had high walls, single entry points and layouts meant to confuse invaders.

In the mountains of Idaho, some people are recreating that kind of environment. The Citadel is a planned community in which residents would be required to own guns and defend the compound if attacked. Its founders explain:

The Towers and Curtain Wall providing the town’s primary perimeter defense will be inaccessible to tourists. Each Tower will house condos. The wall sections between Towers will be the location for many of the larger homes. By looking at the Artist’s Concept (left) you can see that housing will be well-removed from tourist foot-traffic. The Perimeter Road follows the Curtain Wall.

Each neighborhood within the walls will have lower defensive walls, dividing the town into defensible sections/neighborhoods. Each neighborhood will have similar housing for visual uniformity and aesthetic appeal.

But The Citadel is a project designed to appeal to only a subset of Americans. Is there a way for architects to design more run-of-the-mill buildings to keep their residents safe, without just building a medieval castle?

In places that faced violence already, like Newtown, Conn., or the Sikh Temple in Oak Creek, Wisc., architects might consider not just how to make buildings that are safer in practice but that allow the community that uses them to feel safe. In the New Yorker, Thomas De Monchaux writes:

Shootings, events defined by immediate sightlines and ballistic trajectories, are an especially spatial and architectural kind of violence, and some ineffable part of their violence is to space itself—to the very airspace or geographical coördinates at which shots were fired or taken. The architectural task in the long aftermath of such shootings is not only to repair structural damage but to calibrate a balance between remembering and forgetting sufficient for daily life to continue nearby—and to figure out how the shapes, materials, and details of buildings can participate in that calibration. The architectural task is not only to provide actual security and defensibility but to figure out how the ways you see and move through buildings can affect your feelings of being at risk or at home.

Rebuilding with that sort of security, though, can be tricky. Adding big metal bars on the doors and windows of a school has downsides, especially if you’re trying to construct a place where kids will want to learn. Architectural Record had a story about these challenges just after Newtown, writing:

While fortress-like buildings with thick concrete walls, windows with bars, and special security vestibules may be more defensible than what is currently in vogue, they are hardly the kind of places that are optimal for learning. Edmund Einy, a principal at GKKWorks, says that what’s been done so far in many urban schools in the name of safety—such as slapping bars on the windows—has had a pernicious effect on students’ morale and performance. Einy’s new Blair International Baccalaureate Middle School, in Pasadena, foregoes bars. But administrators must greet students before they are allowed to go inside, which led GKKWorks to create an entry plaza. “There’s not much more we can do,” he says. “What are we going to do, put kids in prisons?”

Others argue that this is not a job for architects; it’s a job for politicians and people. Smart Planet’s C.C. Sullivan writes:

So answering the question posed by architect Peter Normand, perhaps we need to build as many reminders of our “gun-saturated society” and gun tragedies as we need protections against them.

Instead of panic rooms in every home and classroom, we need more symbols of awareness. Instead of new building codes and bulletproof doors, let’s open the shades on who we are.

Feeling safe, Sullivan argues, takes more than just physical design. It takes cultural design, too. Perhaps it’s not the job of the architect to keep us safe.

A stealth B-2 bomber. Photo: U.S. Air Force

Three weeks ago North Korea announced that if joint U.S.-South Korea military exercises were not called off by March 11 then they would consider the sixty-year old armistice between the two Koreas null. March 11 has come and gone. The U.S. and Korea are still exercising their militaries, and North Korea is still not happy about it. At all.

In an act that certainly didn’t de-escalate the situation, the U.S. sent a pair of B-2 stealth bombers cruising over the Korean peninsula. The two bombers left from Whiteman Air Force Base in Missouri, says the Atlantic Wire, buzzed South Korea’s western coast, and then returned home.

Obviously, the test run demonstrates that the U.S. has the capability of flying that far without actually crossing into North Korea and it appears to be meant to send a message that the U.S. is willing to defend South Korea against the North. There’s also probably some historical symbolism thrown in. Hun adds, “After suffering from the American carpet-bombing during the 1950-53 Korean War, North Korea remains particularly sensitive about U.S. bombers.”

“The US defence secretary, Chuck Hagel,” says the Guardian, “said that the decision to send B-2 bombers to join the military drills was part of normal exercises and not intended to provoke North Korea.”

But it did.

In response to the flights, says the BBC, North Korea trained its missiles on American and South Korean military bases, with the North Korean state news agency reporting that “the US mainland, their stronghold, their military bases in the operational theatres in the Pacific, including Hawaii and Guam, and those in South Korea” were all being targeted.

As the BBC reports, “Russia has warned of tensions in North Korea slipping out of control… Russian Foreign Minister Sergei Lavrov warned the situation could slip “toward the spiral of a vicious circle”.

Though North Korea has a long history of making quite threatening displays, an unnamed U.S official told NBC News that “North Korea is “not a paper tiger” and its repeated threats to attack South Korea and the U.S. should not be dismissed as “pure bluster.”

From 1922 to 1943, when Allied troops took Sicily nearing the end of World War II and his power began to wane, Benito Mussolini ruled Italy as its fascist dictator. As Italy suffered defeats throughout the war and as the Allied forces pushed ever closer, Mussolini became increasingly paranoid, says The Telegraph, fearing that the Royal Air Force, “was planning to launch an audacious raid on his headquarters in an attempt to kill him and knock Italy out of the war.”

His fears were well founded – the RAF had indeed drawn up a plan to launch a bombing raid on the palazzo, as well as his private residence in Rome, Villa Torlonia, using the 617 Squadron of Dambusters fame.

In response to the encroaching forces, Mussolini set about constructing a series of fortified bunkers. One such bunker, buried beneath Mussolini’s headquarters in Rome, was discovered recently during maintenance. The bunker will soon be opened to the public.

The bunker was discovered three years ago when engineers carrying out structural work on the foundations of Palazzo Venezia noticed a small wooden trap door.

It opened out to a narrow flight of brick stairs which in turn led to the bunker, divided into nine rooms by thick concrete walls.

The structure was so deep that it had exposed some Roman remains, which are still visible today.

This is not the first of Mussolini’s bunkers discovered, says Yahoo! News, but rather the twelfth. The building it is buried beneath, the Palazzo Venezie, “currently houses a national museum and has been a historically significant structure for centuries, having been used by high ranking members of the Roman Catholic Church and other important figures over the years.”

The bunker was first discovered in 2011, says La Stampa, “but has only been revealed now.”

If you’ve brushed up on your Italian (or if you don’t mind not knowing what’s going on), here’s a tour of the relic bunker.

In 1968, the Paris Peace talks, intended to put an end to the 13-year-long Vietnam War, failed because an aide working for then-Presidential candidate Richard Nixon convinced the South Vietnamese to walk away from the dealings, says a new report by the BBC’s David Taylor. By the late 1960s Americans had been involved in the Vietnam War for nearly a decade, and the ongoing conflict was an incredibly contentious issue, says PBS:

In 1967, with American troop strength in Vietnam reaching 500,000, protest against U.S. participation in the Vietnam War had grown stronger as growing numbers of Americans questioned whether the U.S. war effort could succeed or was morally justifiable. They took their protests to the streets in peace marches, demonstrations, and acts of civil disobedience. Despite the country’s polarization, the balance of American public opinion was beginning to sway toward “de-escalation” of the war.

Nixon’s Presidental campaign needed the war to continue, since Nixon was running on a platform that opposed the war. The BBC:

Nixon feared a breakthrough at the Paris Peace talks designed to find a negotiated settlement to the Vietnam war, and he knew this would derail his campaign.

… In late October 1968 there were major concessions from Hanoi which promised to allow meaningful talks to get underway in Paris – concessions that would justify [President Lyndon] Johnson calling for a complete bombing halt of North Vietnam. This was exactly what Nixon feared.

President Johnson had at the time a habit of recording all of his phone conversations, and newly released tapes from 1968 detailed that the FBI had “bugged” the telephones of the South Vietnamese ambassador and of Anna Chennault, one of Nixon’s aides. Based on the tapes, says Taylor for the BBC, we learn that in the time leading up to the Paris Peace talks, “Chennault was despatched to the South Vietnamese embassy with a clear message: the South Vietnamese government should withdraw from the talks, refuse to deal with Johnson, and if Nixon was elected, they would get a much better deal.” The Atlantic Wire:

In the recently released tapes, we can hear Johnson being told about Nixon’s interference by Defence Secretary Clark Clifford. The FBI had bugged the South Vietnamese ambassadors phone. They had Chennault lobbying the ambassador on tape. Johnson was justifiably furious — he ordered Nixon’s campaign be placed under FBI surveillance. Johnson passed along a note to Nixon that he knew about the move. Nixon played like he had no idea why the South backed out, and offered to travel to Saigon to get them back to the negotiating table.

Though the basic story of Nixon’s involvement in stalling the Vietnam peace talks has been around before, the new tapes, says the Atlantic Wire, describe how President Johnson knew all about the on-goings but chose not to bring them to the public’s attention: he thought that his intended successor, Hubert Humphrey, was going to beat Nixon in the upcoming election anyway. And, by revealing that he knew about Nixon’s dealings, he’d also have to admit to having spied on the South Vietnamese ambassador.

Eventually, Nixon won by just 1 percent of the popular vote. “Once in office he escalated the war into Laos and Cambodia, with the loss of an additional 22,000 American lives, before finally settling for a peace agreement in 1973 that was within grasp in 1968,” says the BBC.

Enver Hoxha was as paranoid a dictator as they come. During his forty-year reign over Albania, in addition to generously dishing out death sentences and long prison terms for anyone who opposed him, he organized the building of more than 700,000 bunkers, or one for every four inhabitants in his country. Dubbed the “bunkerisation” program, the shelters were finally abandoned after Communism’s collapse.

The bunkers were never used since the military threat Hoxha imagined never arrived, and their construction drained Albania’s economy and diverted resources away from other, more pressing needs, such as road and housing improvement. On average, there are 24 bunkers for every square kilometer in Albania. Most of these unsightly concrete mushrooms still mar the landscape today, from mountain tops to cities to beaches.

Most bunkers are wasting away into the landscape, but some are used as shelters for animals or the homeless, or as kitschy cafes. Reportedly, their most common use now is sheltering amorous young Albanians looking for some privacy. Wired describes the problem:

Today, Albanian authorities are at a loss for what to do. The reinforced concrete domes are as difficult to repurpose as they are to destroy. Tourists are fascinated by the bunkers strewn like confetti across scenery, but for locals they’re a largely uninteresting, if obstructive, part of the landscape.

Besides being an eyesore, the bunkers really do pose problems for people. Expatica reports:

At least five holidaymakers, including two children and a 25-year-old woman, drowned last summer in whirlpools created by streams around the bunkers which are covered by slime, cracked and damaged by erosion.

In 2009, the government set out to take some action against the bunkers, recruiting old tanks to blow the ugly domes to smithereens.  But things did not go as smoothly as planned—after two weeks only seven had been dealt with. Locals, too, usually fail at attempts to rid their land of the things. Expatica:

Some Albanians have tried to remove them on their own, but their efforts usually end in vain, leaving them resigned to living with the structures they refer to as “mushrooms.”

Some have converted them into sheds, toilets or even “zero-star hotels” for lovers, as they sometimes call the bunkers.

For curious tourists, however, some bunkers now serve as youth hostels. According to the BBC, a couple entrepreneurial students have set out to convert bunkers across the country into unique abodes for travels. If the project manages to be a success, the team said they’ll charge about 8 euros per night for the privilege of sleeping in a genuine Albanian bunker.
