Good Morning!
Let’s take a break today from the usual stuff. Let’s chase down the kewl!!
The world’s largest cave has been discovered in Vietnam. They’re getting ready to give tours!!
The Son Doong Cave in Vietnam is the biggest cave in the world. It’s over 5.5 mileslong, has a jungle and river, and could fit a 40-story skyscraper within its walls.
But nobody knew any of that until four years ago.
A local man discovered the cave entrance in 1991, but British cavers were the first to explore it in 2009. Now, tour company Oxalis is running trial tours of the cave andaccepting sign-ups for real six-day tours to take place next year.
The man who discovered Son Doong didn’t go in because the entrance he found had too steep a drop. On next year’s tours, visitors will rappel 80 meters to
enter Son Doong.
The world’s largest volcano has been discovered beneath the Pacific Ocean.
Scientists say that they have discovered the single largest volcano in the world, a dead colossus deep beneath the Pacific waves.
A team writing in the journal Nature Geoscience says the 310,000 sq km (119,000 sq mi) Tamu Massif is comparable in size to Mars’ vast Olympus Mons volcano – the largest in the Solar System.
The structure topples the previous largest on Earth, Mauna Loa in Hawaii.
The massif lies some 2km below the sea.
It is located on an underwater plateau known as the Shatsky Rise, about 1,600km east of Japan.
It was formed about 145 million years ago when massive lava flows erupted from the centre of the volcano to form a broad, shield-like feature.
The researchers doubted the submerged volcano’s peak ever rose above sea level during its lifetime and say it is unlikely to erupt again.
“The bottom line is that we think that Tamu Massif was built in a short (geologically speaking) time of one to several million years and it has been extinct since,” co-author William Sager, from the University of Houston, US, told the AFP news agency.
“One interesting angle is that there were lots of oceanic plateaus (that) erupted during the Cretaceous Period (145-65 million years ago) but we don’t see them since. Scientists would like to know why.”
Prof Sager began studying the structure two decades ago, but it had been unclear whether the massif was one single volcano or many – a kind that exists in dozens of locations around the planet.
While Olympus Mons on Mars has relatively shallow roots, the Tamu Massif extends some 30 km (18 miles) into the Earth’s crust.
Scientists say there is a sixth sense and its not what you think it is.
Until recently, however, scientists weren’t able to locate it, which had led to some skepticism as to whether a map for numerosity exists.
Benjamin Harvey of Utrecht University and his colleagues have discovered signals that show that the much-debated numerosity map really does exist.
Numerosity is different from symbolic numbers.
“We use symbolic numbers to represent numerosity and other aspects of magnitude, but the symbol itself is only a representation,” Harvey noted.
Numerosity selectivity in the brain comes from visual processing of image characteristics, where symbolic number selectivity comes from the recognition of the shapes of numerals, written words, and linguistic sounds that represent numbers.
“This latter task relies on very different parts of the brain that specialize in written and spoken language,” Harvey added.
To discover the map, Harvey and his colleagues asked eight study participants to examine patterns of dots that differed in number over time, all the while studying the neural response properties in a numerosity-associated part of their brain utilizing high-field fMRI. This technique allowed the researchers to scan the subjects for far less time per session than would have been necessary with a less powerful scanning technology.
Harvey and his team turned to population receptive field modelling to measure neural response.
“This was the key to our success,” Harvey posited.
It allowed the scientists to model the human fMRI response properties they saw following results of recordings from macaque neurons, in which numerosity experiments had been conducted more fully.
They discovered a topographical layout of numerosity in the human brain: the small amounts of dots the participants saw were encoded by neurons in one area of the brain, the bigger amounts, in another.
The discovery shows that topography can also develop for higher-level cognitive functions.
“We are very excited that association cortex can produce emergent topographic structures,” Harvey said.
So, BB knows me and knows my fascination with graves. It seems a badger has unearthed a treasure trove of medieval European graves.
A badger has led German archaeologists to a stunning find of medieval warrior graves, complete with one skeleton still clutching a sword and a wearing snake-shaped buckle on his belt.
Scientists are now examining the burial site where at least eight people were buried.
Artist and voluntary monument maintenance man Lars Wilhelm said he was watching badgers near his home in Brandenburg, north Germany, when he realized they were digging into an ancient grave.
He said he had been watching the progress of an enormous badger sett for five years. “My wife and I – we are both sculptors – wanted to put artworks in there.”
But this was now out of the question, he said. “The bones changed everything,” he added.
The Berliner Zeitung newspaper said Wilhelm called the experts as soon as he realized the animals had dug up bones. Archaeologists moved in and expanded the work of the badgers, freeing up eight graves, two of which were of noblemen.
“These are late Slavish graves,” said Professor Felix Biermann from the Ernst-August University in Göttingen, who is leading the dig in the Uckermark Stolpe area. He said they dated from the first half of the 12th century AD.
“Apart from these last heathen Slavs, the whole surrounding area was already Christianized. It’s special because these rulers still had their independent heathen beliefs.”
The warrior graves were particularly exciting. The skeleton of one man, aged around 40, was complete with a two-edged sword, and a bronze bowl at his feet.
“At the time such bowls were used to wet the hands before eating,” said Biermann. “The bowls would a sign that a man belonged to the upper classes.”
He added that the warrior also had a bronze buckle with a snake’s head, which probably came from Scandinavia. His grave also contained an arrow head.
“He was a well-equipped warrior. Scars and bone-breaks show that he had been hit by lances and swords, and had also fallen from a horse.”
While the international community debates what to do about Syria, evidence of the use of chemical weapons dating back 1,700 years has surfaced.
British archeologist Dr Simon James believes 20 Roman soldiers may have been killed by lethal poisonous gas during a Persian attack on their fort at Dura-Europas in Eastern Syria during the 3rd century.
If true, it would be one of the earliest documented incidents of chemical weapons.
The soldiers met their fate in a narrow space in around 256AD, according to a statement by the University of Leicester academic in 2009.
Speaking at the time, Dr James said: ‘For the Persians to kill 20 men in a space less than two metres high or wide, and about 11 metres long, required superhuman combat powers, or something more insidious.
‘I think the (Persians) placed braziers and bellows in their gallery, and when the Romans broke through, added the chemicals and pumped choking clouds into the Roman tunnel.
‘The Roman assault party were unconscious in seconds, dead in minutes.’
Dr James was alerted to the evidence by mineral residue near the bodies. He concluded the gas was created by adding a compound of burnt bitumen and sulfur to fire.
So, there’s some interesting stuff to get our minds off the current problems. I’m going to let you get us up to date today. What’s on your reading and blogging list today?

Saturday: Of War, Fracking, and Fukushima
Posted: September 7, 2013 Filed under: just because 41 CommentsHave you read Rosa Brooks’ “Obama Can’t Win“ in Foreign Policy magazine yet? If not, go read it now. Teaser:
Oddly, many in the media seem convinced that Obama’s pledge to seek congressional authorization for a Syria intervention was a clever gamble. It wasn’t. It was, to paraphrase Obama, a dumb gamble. That’s because there is now no good outcome for Obama, only a range of painfully ironic outcomes.
It’s an excellent read. Please take a moment to look it over.
Something interesting… note the title of the latest from FoPo’s David Rothkopf, “How the Loneliest Job in the World Got Even Lonelier,” (bylined “With his missteps on Syria, Obama has alienated just about everyone — friends and frenemies alike.”) Sounds a lot like Glen Ford’s bottom line over at Black Agenda Report… “Obama: As Warlike as Bush, and Just as Lonely.”
Cue The Onion:
Nation Throws Giant Temper Tantrum Upon Learning Syria Is Complex, Nuanced Issue
I have to tell you that what’s not helping sort any of this complexity or nuance is Kerry and Obama suddenly embracing action that will have the side effect of empowering the rebels…I can only take wild guesses as to what changed in the Administration’s assessment of the situation, because Assad gassing his own people doesn’t mean the rebels are suddenly the lesser evil. As the Onion points out in the news skit above, the Syria situation doesn’t fit neatly into a narrative of “the good guys” and “the bad guys.”
Along those lines, here is the first installment of Reader Supported News’ three part series on Syria: Where Revolution Goes Wrong.
A couple excerpts…
Independent journalist Anna Therese Day has spent considerable time in Syria, and last year authored a Shorty Award-nominated report for VICE Magazine called Gunrunning with the Free Syrian Army. In the report, Day accompanied an FSA colonel who defected from Assad’s army when the mass killings began. The colonel had two main complaints: that Western governments had abandoned the Syrian people in spite of mass genocide and brutal killings of protesters, and that because of the absence of help from Western governments, the Syrian people have had to depend on the military might of jihadists like the group Jabhat Al-Nusra. The jihadists fighting alongside the Free Syrian Army have the much different objective of establishing a theocratic Islamist government, whereas the FSA’s objectives are more along the lines of establishing a democratic and accountable secular government.
“Academic studies show empirically that civil resistance is more effective than armed resistance,” Day told me in a Skype interview from Madrid. “But it’s difficult to expect people to adhere to these ivory tower principles, even if in the long-term it will be more effective, when they are being attacked and need to defend to their families.”
And, yet…
Erica Chenoweth, an International Studies professor at the University of Denver, is author of the book “Why Civil Resistance Works.” In a February 2012 presentation at Dartmouth College, she explained how she was originally skeptical that nonviolence could accomplish major political goals, and decided to place very strict limits on which nonviolent campaigns she would credit with achieving major political goals. Chenoweth focused only on campaigns where there were more than 1,000 active participants using a majority of nonviolent tactics like boycotts, strikes, and street demonstrations over a small period of time. She also studied only nonviolent campaigns that were focused on achieving extremely difficult goals like regime change, removing an occupying military force, or seceding territory.
Chenoweth found that between 1900 and 2006, nonviolent campaigns were twice as effective as violent campaigns, and that in that time period, nonviolence became an increasingly effective strategy for achieving major victories, whereas violence became increasingly ineffective. Chenoweth’s research on violent campaigns found that their strategy was limited to simply getting as many people with as many weapons as possible and challenging the state head-on through either direct warfare or guerrilla tactics like sabotage and assassinations. Chenoweth’s research found that for a violent campaign to be effective at either ousting a regime or removing an occupying military force, it had to wage a long-term struggle against the state with the aforementioned tactics to corrode the state’s ability to assert power over the people, and it had to sustain its efforts over a long period of time. Because the state has a monopoly on violence, with more resources at its disposal, those violent campaigns had a very small rate of success.
However, Chenoweth discovered that nonviolent campaigns, with the various tactics at their disposal, were much more successful. They could attact a vast multitude of diverse people, and so were able to sustain a long campaign aimed at accomplishing specific strategic goals. Nonviolence succeeded where violence didn’t: the OTPOR movement’s ousting of Slobodan Milosevic in Serbia; the Arab Spring’s ousting of Ben Ali in Tunisia. A nonviolent campaign can use leverage to remove all pillars of support for an oppressive regime or an occupying military force.
This first installment ends on a rather chilling note (well, I found it chilling at least) from the journalist mentioned above — Anna Therese Day:
Regardless of whether or not the US chooses to intervene with either humanitarian aid or airstrikes, Anna Day says that the Assad regime is likely to win out against the violent campaign to oust him. She says she’s troubled by the Obama administration’s unilateral plans for intervention, and other plans that have been discussed to arm rebels with more sophisticated weaponry.
“Assad controls most of the country and won back major key swaths in August, so this notion that he doesn’t have legitimacy anywhere simply isn’t true,” Day said. “It’s debatable if the rebels – not the cause of the Revolution, but the rag-tag leadership of the armed resistance – have any legitimacy at all, even among anti-Assad civilian elements.”
I don’t know how to pivot from that gracefully to a more uplifting story, so… how about we go even deeper in Debbie downer territory with some… ‘fracking confirmation.’
Confirmed: Fracking practices to blame for Ohio earthquakes. From the NBC News Science link:
Before January 2011, Youngstown, Ohio, which is located on the Marcellus Shale, had never experienced an earthquake, at least not since researchers began observations in 1776. However, in December 2010, the Northstar 1 injection well came online to pump wastewater from fracking projects in Pennsylvania into storage deep underground. In the year that followed, seismometers in and around Youngstown recorded 109 earthquakes, the strongest registering a magnitude-3.9 earthquake on Dec. 31, 2011. The well was shut down after the quake.
Scientists have known for decades that fracking and wastewater injection can trigger earthquakes. For instance, it appears linked with Oklahoma’s strongest recorded quake in 2011, as well as a rash of more than 180 minor tremors in Texas between Oct. 30, 2008, and May 31, 2009.
The new investigation of the Youngstown earthquakes, detailed in the July issue of the journal Geophysical Research Letters, reveals that their onset, end and even temporary dips in activity were apparently all tied to activity at the Northstar 1 well.
Well, gee, isn’t that swell. Say… Anyone care for the latest on Fukushima?
Via BBC: South Korea bans fisheries imports from Fukushima area…
South Korea has banned all fisheries imports from eight Japanese prefectures, amid concern over leaks of radioactive water from the crippled Fukushima nuclear plant.
A spokesman said the measure was due to “sharply increased” public concern about the flow of contaminated water into the sea.
The ban, an expansion of existing restrictions, takes effect on Monday.
Meanwhile via CNN, Fukushima: The long road home after 2011 disaster. From the link:
More than a year ago, the workers here wore full protection suits, today they simply wear gloves and the basic face masks you can see anywhere in Japan — a sign that the radiation level here has dropped.
Thousands of industrial-size black bags hold the contaminated soil. They are lined up in fields, waiting for their final resting place — wherever that may be. This is a reminder that the problem of what to do with radioactive water at the crippled Fukushima plant is not the only storage issue this country has to deal with.
During the day, the steady volume of traffic in this outer part of the exclusion zone belies the invisible threat that still exists. It’s a threat that two-and-a-half years later has residents wondering when, or even if, they will be able to move back home.
I’m sorry to have such a depressing roundup for you this Saturday. What can I say. It’s almost September 11th, and we’re on the precipice of another possible war. It wouldn’t be a relevant roundup if it weren’t depressing.
But, you know me. Still hoping against hope! So, here’s my feminist treat for you before I go. The latest ‘Blurred’ parody by some outstanding law students in Auckland, NZ… my favorite so far, by far:
Alright, Sky Dancers. Let’s hear it in the comments. And, have a great weekend!

Good Morning!
I am enjoying the cooling effects of the new AC condenser. The last days of summer heat will be with us here in New Orleans for awhile so I am glad I could replace it. There are a bunch of other things that I will now go without but the AC is one thing you cannot forgo down here any more.
It’s difficult to find some things that aren’t about Syria, but I did find a few things just to give us a break. I am going to start one with item that broke late last night.
The WSJ has says the US has intercepted a message that states that Iran will attack Iraq if the US attacks Syria.
The U.S. has intercepted an order from Iran to Shiite militants in Iraq to attack the U.S. Embassy and other American interests in Baghdad in the event of a strike on Syria, officials said, amid an expanding array of reprisal threats across the region.
Military officials have been trying to predict the range of possible responses from Syria, Iran and their allies. U.S. officials said they are on alert for Iran’s fleet of small, fast boats in the Persian Gulf, where American warships are positioned. U.S. officials also fear Hezbollah could attack the U.S. Embassy in Beirut.
While the U.S. has positioned military resources in the region for a possible strike, it has other assets in the area that would be ready to respond to any reprisals by Syria, Iran or its allies.
Those deployments include a strike group of an aircraft carrier and three destroyers in the Red Sea, and an amphibious ship, the USS San Antonio, in the Eastern Mediterranean, which would help with any evacuations.
The U.S. military has also readied Marines and other assets to aid evacuation of diplomatic compounds if needed, and the State Department began making preparations last week for potential retaliation against U.S. embassies and other interests in the Middle East and North Africa.
I think we all can agree on the level of skepticism felt here–both writers and discussants–on the weird cult of libertarians. Here’s an interesting thought. Are Libertarians the New Communists?
Most people would consider radical libertarianism and communism polar opposites: The first glorifies personal freedom. The second would obliterate it. Yet the ideologies are simply mirror images. Both attempt to answer the same questions, and fail to do so in similar ways. Where communism was adopted, the result was misery, poverty and tyranny. If extremist libertarians ever translated their beliefs into policy, it would lead to the same kinds of catastrophe.
Let’s start with some definitions. By radical libertarianism, we mean the ideology that holds that individual liberty trumps all other values. By communism, we mean the ideology of extreme state domination of private and economic life.
Some of the radical libertarians are Ayn Rand fans who divide their fellow citizens into makers, in the mold of John Galt, and takers, in the mold of
anyone not John Galt.
Some, such as the Koch brothers, are economic royalists who repackage trickle-down economics as “libertarian populism.” Some are followers of Texas Senator Ted Cruz, whose highest aspiration is to shut down government. Some resemble the anti-tax activist Grover Norquist, who has made a career out of trying to drown, stifle or strangle government.
Yes, liberty is a core American value, and an overweening state can be unhealthy. And there are plenty of self-described libertarians who have adopted the label mainly because they support same-sex marriage or decry government surveillance. These social libertarians aren’t the problem. It is the nihilist anti-state libertarians of the Koch-Cruz-Norquist-Paul (Ron and Rand alike) school who should worry us.
Economics Policy Wonk Jared Bernstein has a great narrative on how fiscal policy gets so mixed up. He attempts to explain how our economic knowledge in theory has warped into something unrecognizable in the beltway.
I identify three reasons why fiscal policy became so backwards in recent years. First, a strategy by Democrats to block the GW Bush tax cuts morphed from strategy to ideology. Second, a misunderstanding of the Clinton surpluses in ways explained below. And third, the use of deficit fear-mongering to achieve the goal of significantly shrinking the government sector.
During the early years of the GW Bush administration, the President proposed and Congress passed two tax-cut packages that quite sharply lowered the revenues flowing to the Treasury. During those debates, opponents of the cuts raised their negative impact on deficits and debt as a major concern. Such concerns proved to be justified. As Ruffing and Friedman show (2013), instead of its actual slowly rising path, the debt ratio would have been falling in the latter 2000s but for the Bush tax cuts (war spending played a much smaller role). In my terminology, GW Bush fiscal policy was that of an SD (structural dove), adding to the debt ratio throughout the expansion of the 2000s.
Many who were making those anti-tax-cut arguments cited the Clinton years as an instructive counter-example. The lesson of those years, they argued, was that by increasing taxes and restraining spending, the Clinton budgets both led to surpluses and assuaged bond markets leading to lowering borrowing costs, more investment, and faster growth. In fact, while fiscal policy in Clinton’s first budget did lower projected deficits, as discussed above [earlier in the paper I point out that if you track the swing from deficit to surplus from 1993-2000, Clinton fiscal policies explain one-third of the change; even once these changes were in the baseline, in 1996, CBO still projected deficits a few years later, when in fact the budget went into surplus, so Clinton fiscal policy cannot get credit for that part of the swing], economic growth was far the larger factor (the fact that much of this growth was a function of a dot.com bubble is a separate issue).
Together, this line of attack against the Bush tax cuts in tandem with the over-emphasis on Clinton fiscal policy as the factor that led to surpluses, raised the budget deficit to a new level in the national debate. Deficit hawkish pundits, editorial pages, and policy makers knew two things: Clinton raised taxes, cut spending, and balanced the budget; Bush cut taxes, failed to restrain spending, and added to the debt ratio.
Again, reality was more complex. Economic growth was the major factor behind the Clinton surpluses, and while GW Bush’s tax cuts clearly added to the deficit and debt, even under his quite profligate fiscal policy, the deficit-to-GDP ratio fell to about 1% in 2007 (below primary balance). To be clear, this is no endorsement of his structural dovishness. That was the last year of that business cycle expansion, and as I argue later in the paper, it’s important to get the debt ratio on a downward path much sooner than that. But the collision of these two different approaches to fiscal policy in two back-to-back decades helped to construct a conventional wisdom about budget deficits as a national scourge that had more to do with cursory observation than economic analysis.
Another important factor, perhaps the most consequential, in the evolution of these wrong-headed ideas was the partisan ideology that government should be much smaller as a share of the economy. For conservatives who shared this vision, elevating the issue of the budget deficit as a major national problem was and remains a highly effective strategy. If they could convince the public and their representatives that deficits had to be reduced no matter what, than cutting the federal budget should be a short step away.
I’ve studied game theory as part of my graduate program and taught game theory as part of my classes. This study shows why author Julie Beck of The Atlantic Magazine says it’s the gift that keeps on giving. A new study shows that generosity is more advantageous than selfishness.
Results: In the long term, extorting, selfish strategies did not work as well as more generous strategies. Players who defected instead of cooperating suffered more over time than players who recognized the value of cooperation–though extortion might provide an advantage in a single head-to-head matchup, in the context of a whole population, over time, it pays to be generous. Sometimes cooperative players would even forgive those who defected and cooperate with them again.
The researchers created a mathematical proof that shows, as study co-author Joshua B. Plotkin said in an email, “why generosity abounds in nature, despite the fact that it may appear self-detrimental in the short-term.”
Implications: Now we have some mathematical evidence that there is an evolutionary advantage to generosity, other than just good karma. With Darwin’s “survival of the fittest” ingrained in our brains, it often seems like every man for himself is the best strategy, and kindness is just an anomaly. But it’s an uplifting surprise to see a study that says that’s not the case, that we evolve best when we help each other.
This seems like an argument for the feminine and against the masculine to me.
Anyway, that’s my offerings today. What’s on your reading and blogging list?
