What the octopus can teach us about national security


What the octopus can teach us about national security

How can governments ensure their armed forces are protected in the field? By behaving like the tentacled marine animal, argues a marine scientist. 

When American soldiers were killed in Iraq by improvised explosive devices, or IEDs, it was the slow, bureaucratic, centralised nature of the Department of Defense that failed them, says Rafe Sagarin, a marine ecologist at the University of Arizona. It was only once soldiers were authorised to make their own decisions – a move known as the Petraeus Doctrine, after the general who invented it – that they could communicate effectively with locals in order to find out in advance where IEDs might be.
Why was a marine ecologist suggesting ways of protecting armed forces? Well, according to Sagarin, the Petraeus doctrine is exactly the sort of thing an octopus would do. Despite its well-organised central nervous system, many of an octopus's reactions are decentralised. Its individual cells make their own decisions for dealing with the immediate situation – enabling, for example, the invertebrate's famously varied camouflage. Switching to this kind of adaptive tactics provided greater protection for soldiers in Iraq.
Sagarin's insights about the relevance of the octopus to matters of national security are captured in his book Learning From the Octopus: How Secrets from Nature Can Help Us Fight Terrorist Attacks, Natural Disasters, and Disease. The book is more than just speculation: he spent years running National Science Foundation-funded workshops that included biologists, ecologists, anthropologists, first responders and national security experts, all of whom were charged with the task of figuring out how to make America's military and security apparatus more adaptable.
The unusual story of how a marine ecologist ended up in Congress, as a science advisor to US Representative Hilda Solis of California's 31st district, and later as an author of a book that's grown to be a cult favourite among national security types, began during the events of 9/11. When the twin towers of the World Trade Center went down, Sagarin was in one of his most beloved habitats – a marine tidepool in Monterrey Bay, California.
"On the day of those attacks, I was feeling very far removed from what was going on at in Washington and New York," says Sagarin. But he'd always had an interest in policy, so he applied for and received a Geological Society of America Congressional Science Fellowship.
That led to an article in Foreign Policy called Adapt or Die, in which he declared: “If the genus Americanus wants to overcome this latest challenge to its existence, it must adapt its defense mechanisms accordingly. What better way to do that than to harness time-tested Darwinian theory to the cause of homeland security?”


Tentacled tactics
The lessons Sagarin ultimately derived from the natural world surprised even him. "I'm a cynic about generalism in biology and ecology, because systems are so complex," he says. "It took us a while to come to the point where we had any rules at all."
The first rule he derived was, as in the case of the octopus's camouflage and the Petraeus Doctrine, the importance of decentralisation. This, he notes, was the opposite of what America was doing in security at the time, for example with the creation of a centralised, Washington DC-based Department of Homeland Security, which was founded expressly to be a clearinghouse for formerly-dispersed decision-making about security.
The second principle Sagarin and his collaborators noticed was the importance of symbiosis. Nearly all organisms depend on at least one or two – and in some cases many – other species. As an example of how this manifests in security, Sagarin cites the Middle East Consortium on Infectious Disease Surveillance (MECIDS), which brings together Israeli and Palestinian doctors in order to track the spread of infectious diseases like the H1N1 influenza virus. Given the intense political differences between the two countries – the organization spans both the Gaza Strip and the West Bank – its as unlikely a collaboration as you'll find, and yet it works because "they're intensely focused on solving this one set of problems, and nothing else," says Sagarin.
Another lesson from the octopus is that adaptability requires redundancy. "We think of redundancy as wasteful and inefficient, but it's everywhere in nature," he notes.


Defensively and offensively, an octopus has no shortage of coping mechanisms – camouflage, powerful arms, intelligence, a sharp beak, symbiotic toxins and a cloud of ink. When escaping, it can squeeze into a tight space, blend in with the background, jet away, and, in the lab at least, grab two halves of a coconut shell and sequester itself inside them.


Unknown unknowns
Just as importantly, Sagarin discovered what it is that organisms don't do. In general, they don't plan, predict or try to be perfect. When Sagarin tells this to the members of strategic planning departments in government agencies, it leads to "a lot of consternation and grinding of teeth," in part because it's so counter-intuitive.
Indeed, if there is a single message that sums up all of Sagarin's work, it's that organisms realized long ago that the world is a much less predictable place than humans would like to believe. What Sagarin calls the "non-normal distribution of truly interesting events," which was explored at length in Nassim Taleh's book The Black Swan, has relevance to how we'll cope with everything from disease outbreaks to climate change.
"We spend a lot of time in planning exercises, making predictive models, and in optimization routines," says Sagarin. "All of which have essentially been selected against in nature, because they're incredibly wasteful when you live in an unpredictable world."
Organisms and humans should plan for things that occur with some frequency; buildings in earthquake-prone areas must be ready for tremors just as surely as mating Horseshoe crabs need to know the phase of the moon. But the biggest dangers are those we've yet to identify, and if nature is any guide, the only way to prepare for them and respond to them effectively is to have an abundance of flexibility and skills which can be combined to meet any challenge.

Healthcare ruling to save billions of dollars, says CBO


Healthcare ruling to save billions of dollars, says CBO

Hear how voters in a key swing state are split on the Obama health law
US auditors say the Supreme Court ruling upholding President Barack Obama's health law will save the government $84bn (£54bn) over 11 years.
The Congressional Budget Office (CBO) says most of the savings come from the Supreme Court's decision that states do not have to expand Medicaid programmes.
The CBO also found millions fewer poor people than it previously anticipated would be covered because of the ruling.
And it said that repealing the law would raise the deficit by over $100bn.
The law's combined revenue increases and spending cuts are larger than the cost of expanding coverage, according to the CBO's independent analysts.
The Supreme Court decision in June said that states do not have to broaden Medicaid, a government-sponsored health programme for the poor, as set down in the 2010 law.
Who's uninsured?
  • Who's uninsured?
  • Nearly 50 million, or 16.3% of Americans are uninsured
  • By ethnicity, the rate of those who lack insurance is
  • 15.4% White
  • 20.8% Black
  • 18.1% Asian
  • 30.7% Hispanic
  • Source: US Census Bureau
Although the federal government would pick up the initial cost of that expansion, many states would have to open Medicaid to low-income childless adults for the first time.
Expected opt-outs by conservative-led states such as Texas, Florida and South Carolina are projected to decrease the cost of the expansion over the next 10 years.
However, the CBO also estimates about six million fewer people will be covered by Medicaid by 2022 because of the get-out clause.
Republicans, including presidential candidate Mitt Romney, have warned the law will bloat deficits by trillions of dollars, and they are campaigning for its repeal.
But CBO director Douglas Elmendorf said in a letter to Republican House Speaker John Boehner that overturning the law would actually inflate the deficit by $109bn over a decade.
The office also now projects 30 million people will be uninsured by 2022, up from its previous estimate of 27 million people.
The CBO estimates the number of uninsured in the US is now about 53 million and would grow to 60 million in a decade if the law was repealed.

Microsoft makes its first ever loss

Microsoft makes its first ever loss

Microsoft 's advertising business struggled to compete with rival Google

The computing giant Microsoft has made its first-ever quarterly loss after it wrote off some of the value of its online advertising business.
The loss came after it wrote down the value of Aquantive by $6.2bn (£3.94bn, 5bn euros), which failed to bring the profits expected by Microsoft.
That led to a $492m loss in the three months to the end of June, compared with a profit of $5.9bn a year ago.
The company has not made a loss since it joined the stock market in 1986.
It took over aQuantive in 2007 but it struggled to compete with rival Google.
Microsoft paid $6.3bn for Aquantive.
Microsoft is doing well in other areas, despite the decline in popularity of its Windows operating system, which dominated the personal computer market for years.
Revenue for the three months to June rose by 4% to $18.06bn.
Mosaic Excluding the adjustment for the asset write-down, and the holding back of some income related to the launch of its Windows 8 system, Microsoft profits beat those expected by investors.
Shares were up 1.6% after the results were announced.
Microsoft says the update of the Windows systems is the most important redesign in more than 10 years.
Windows 8, which will launch in October, will feature a new look that will present applications in a mosaic of tiles.
Importantly, it will also enable the operating system to work on tablet computers, which along with smartphones are the fastest-growing sector of the computing market.
Microsoft is also planning to release its own tablet, the Surface.
Earlier this week, Microsoft previewed its next version of the Office system, which is expected to be released next year.

Republicans attack Bachmann Muslim conspiracy letter

Republicans attack Bachmann Muslim conspiracy letter

Senior US Republicans have strongly condemned former presidential candidate Michele Bachmann for attacks on a long-time aide to Hillary Clinton.
She said Huma Abedin had connections to the Muslim Brotherhood and implied she was part of a wider conspiracy.
Mrs Bachmann was first criticised by Senator John McCain, then by House Speaker John Boehner and others.
Minnesota congresswoman Mrs Bachmann rose to prominence criticising President Barack Obama in 2008.
She branded the president "un-American" in a TV interview, later becoming a darling of the Tea Party, and founding the Tea Party caucus in the House before launching a presidential bid in 2011.
But her latest statements appear to have angered her party colleagues.
"These attacks on Huma have no logic, no basis and no merit, and they need to stop now," veteran Senator John McCain said on Wednesday.'
Mrs Bachmann, along with four other Republican legislators, wrote a letter to the State Department, along with other government agencies, calling for a probe of Muslim Brotherhood influence in the US government, singling out Ms Abedin.
The letter alleged that she had connections to the Muslim Brotherhood through her family.
'McCarthy level' "From everything I do know of [Huma Abedin], she has a sterling character, and I think accusations like this being thrown around are pretty dangerous," House Speaker John Boehner said.
Senator Lindsay Graham told Politico the charges were "ridiculous" and that Ms Abedin "is about as far away from the Muslim Brotherhood view of women and ideology as you possibly could get".
Mrs Bachmann also received calls to apologise from Representative Keith Ellison, a Democrat who is a Muslim. On cable network MSNBC, he rejected her accusations that the letters had been distorted.
In addition, Mrs Bachmann's former campaign manager Ed Rollins wrote a scathing attack on Fox News' website, saying the Minnesota congresswoman "sometimes has difficulty with her facts, but this is downright vicious and reaches the late Senator Joe McCarthy level".
Sen McCarthy became infamous for his false charges in the 1950s that Communist spies had infiltrated the state department.
As of Wednesday, Mrs Bachmann refused to apologise, saying she would "not be silent as this administration appeases our enemies instead of telling the truth about the threats our country faces".
Ms Abedin, who was also Mrs Clinton's aide during her Senate term, is a Muslim of Pakistani descent who was born in Michigan.
She is married to former Representative Anthony Weiner, who resigned in disgrace last year after sending lewd online photos to other women.
"My family and I are grateful to Senator McCain," Mr Weiner said to the Washington Post on Wednesday. "I think he spoke for many Americans in expressing his disgust for the charge against my wife."

Why we love to hoard… and how you can overcome it

Why we love to hoard… and how you can overcome it

 

Why we love to hoard
(Copyright: Thinkstock)
Understanding the psychology behind why we like to accumulate all manner of items can in fact help you to lead a clutter-free life. 


Question: How do you make something instantly twice as expensive?
Answer: By thinking about giving it away. 


This might sound like a nonsensical riddle, but if you've ever felt overly possessive about your regular parking space, your pen, or your Star Wars box sets, then you're experiencing some elements behind the psychology of ownership. Our brains tell us that we value something merely because it is a thing we have.

This riddle actually describes a phenomenon called the Endowment Effect. The parking space, the pen and the DVDs are probably the same as many others, but they're special to you. Special because in some way they are yours.
You can see how the endowment effect escalates – how else can you explain the boxes of cassette tapes, shoes or mobile phones that fill several shelves of your room… or even several rooms?

No trade

To put a scientific lens on what's going on here, a team led by psychologist Daniel Kahneman carried out a simple experiment. They took a class of ordinary University students and gave half of them a University-crested mug, the other half received $6 – the nominal cost of the mug.
Classic economics states that the students should begin to trade with each other. The people who were given cash but liked mugs should swop some of their cash a mug, and some of the people who were given mugs should swop their mugs for some cash. This, economic theory says, is how prices emerge – the interactions of all buyers and sellers finds the ideal price of goods. The price – in this case, of mugs – will be a perfect balance between the desires of people who want a mug and have cash, and the people who want cash and have a mug.

But economic theory lost out to psychology. Hardly any students traded. Those with mugs tended to keep them, asking on average for more than $5 to give up their mug. Those without mugs didn't want to trade at this price, being only willing to spend an average of around $2.50 to purchase a mug.

Remember that the mugs were distributed at random. It would be weird if, by chance, all the “mug-lovers” ended up with mugs, and the “mug-haters” ended up without. Something else must be going on to explain the lack of trading. It seems the only way to understand the high-value placed on the mugs by people who were given one at random is if the simple act of being given a mug makes you value it twice as highly as before.
This is the endowment effect, and it is the reason why things reach a higher price at auctions – because people become attached to the thing they're bidding for, experiencing a premature sense of ownership that pushes them to bid more than they would otherwise. It is also why car dealers want you to test drive the car, encouraging you in everyway to think about what it would be like to possess the car. The endowment effect is so strong that even imagined ownership can increase the value of something.

Breaking habits

The endowment effect is a reflection of a general bias in human psychology to favour the way things are, rather than the way they could be. I call this status quo bias, and we can see reflections of it in the strength of habits that guide our behavior, in the preference we have for the familiar over the strange or the advantage the incumbent politician has over a challenger.
Knowing the powerful influence that possession has on our psychology, I take a simple step to counteract it. I try to use my knowledge of the endowment effect to help me de-clutter my life. Perhaps this can be useful to you too.

Say I am cleaning out my stuff. Before I learnt about the endowment effect I would go through my things one by one and try to make a decision on what to do with it. Quite reasonably, I would ask myself whether I should throw this away. At this point, although I didn't have a name for it, the endowment effect would begin to work its magic, leading me to generate all sorts of reasons why I should keep an item based on a mistaken estimate of how valuable I found it. After hours of tidying I would have kept everything, including the 300 hundred rubber bands (they might be useful one day), the birthday card from two years ago (given to me by my mother) and the obscure computer cable (it was expensive).

Now, knowing the power of the bias, for each item I ask myself a simple question: If I didn't have this, how much effort would I put in to obtain it? And then more often or not I throw it away, concluding that if I didn't have it, I wouldn't want this.

Let this anti-endowment effect technique perform its magic for you, and you too will soon be joyously throwing away things that you only think you want, but actually wouldn't trouble yourself to acquire if you didn't have them.

And here’s the thing… it works for emails too. If someone sends me a link to an article or funny picture, I don't think "I must look at that", I ask "If I hadn't just been sent this link, how hard would I endeavour to find out this information for myself?". And then I delete the email, thinking that however fascinating that article on the London sewerage system sounds or that funny picture of a cat promises to be, I didn't want them before the email was in my possession, so I probably don't really want them now.
That’s my tip for managing my clutter. If you have any others, let me know.

The American with the other Georgia on his mind

The American with the other Georgia on his mind

Help
American artist John H Wurdeman was drawn to the former Soviet state of Georgia by the country's folk music. Sixteen years later he is still living there, immersed in a culture he says is full of tradition and emotion.
Georgia is a place of "very real tears but also very genuine laughter", says the impressionist painter, 37, who trained at the Surikov Institute in Moscow, Russia.
Wurdeman went to Georgia in 1996 and settled in the town of Signaghi, in the centre of the country's wine region. He lives there with his wife Ketevan and their two children and now runs a winery, Pheasant's Tears, dedicated to preserving Georgian wine culture.
He tells the BBC about his passion for art and wine and why Georgians are more prepared to express emotions to strangers.

Human Microbiome Project reveals largest microbial map

Human Microbiome Project reveals largest microbial map

Illustration showing the 5 areas of the body studied  
Researchers sampled five areas of the body of hundreds of healthy volunteers

Related Stories

"When I get up from my chair, ten times more bacterial cells get up than human ones," says Dr Bruce Birren.
He is one of the hundreds of US scientists involved in the world's most extensive map of the microbes that live in and on us.
The Human Microbiome Project has catalogued the genetic identity of many bacteria, viruses and other organisms that live in intimate contact with us.
They are not germs that need eliminating but a fundamental part of what makes us human, researchers say.

Start Quote

I might have a different organism on my tongue than you do on your tongue but collectively they bring the same genes to the party..”
Dr Bruce Birren Broad Institute of the MIT and Harvard
Yet until recently, little was known about the identity of trillions of the microbes populating our bodies.
'Beneficial bugs' For centuries we could only investigate microbes that can survive in laboratories and study them in isolation - often one microbe at a time.
But with the advent of ever-improving techniques to sequence DNA, the Human Microbiome Project has been able to uncover microbes that have never been seen before and look at how they behave as communities.
Many of the results of the five-year project, launched by the National Institutes of Health, have been published in Nature and PLoS journals.
Over 200 healthy men and women from the US had microbe samples taken from various parts of their bodies.
And researchers were able to find over 10,000 different types of organisms as part of the healthy human microbiome.
Most of these microbes appeared to do no harm at all. In fact, there is growing evidence that these bugs help us in many ways.
Some help us get energy from food and others help us absorb nutrients such as vitamins.

Microbial benefits

  • Microbes help us get energy from food
  • Allow us to absorb vitamins
  • Can help produce molecules which fight against inflammation
  • There is growing evidence that they help develop our immune systems
'Shared microbes?'
And we are learning about the role they play in shaping, rather than just attacking our immune systems, says Prof Barbara Methe of the J Craig Venter Institute, also involved in the project.
One of the key questions researchers asked was - is there a core set of microbes that all humans share?
Scientists actually found a diversity of microbes across different human beings and unique communities of microbes living at different body sites.
But what surprised some is that at specific parts of the body, many of the microbes shared similar jobs.
"I might have a different organism on my tongue than you do on your tongue but collectively they bring the same genes to the party - so they are able to perform some of the same functions, for example, breaking down sugars," Dr Birren says.
Picture of microbes growing in a laboratory Until recently scientists could only identify microbes that could be grown in a laboratory
This finding suggests a shift in thinking from a one-microbe model of disease, that essentially pins the blame for certain illnesses on one bug.
'Bacterial phone-book' Perhaps what matters in some diseases is not the particular type of bug, but that the function of this group of bugs has somehow gone awry, Dr Huttenhower says.
Researchers found that healthy volunteers carry low levels of microbes, classically been thought to cause disease.
For example, the bacteria Staphylococcus aureus, which can be involved the infection MRSA, was found in the noses of about 30 percent.
"We now have a phone-book of 100 of these bugs, which in the right environment, have the potential to go bad.
"We know where they live in healthy people and which organisms surround them too. So perhaps we can begin to understand what keeps them in check and where their reservoirs are," Dr Huttenhower says.

Human Microbiome Project

  • 300 healthy volunteers studied
  • Five body areas investigated - nose, mouth, skin, urogenital tract and gastrointestinal tract
  • Volunteers were sampled up to three times during the study period
  • More than 5,000 samples were collected
  • Over 10,000 different microbes found
And most microbes carry at least 100 times as many genes as we do.
These genes have just as much ability to influence our health and disease-risk as our own, says Dr Curtis Huttenhower, from the Harvard School of Public Health, another contributor to the project.
The ability to refer to this new genetic database and investigate microbiomes that fall outside its boundaries, will be the long-term importance of this project, he says.
'Unknown land' Dr Lita Proctor, programme director of the project says there is a growing understanding that we pick it up in the very early stages of life.
"The human genome is inherited but the human microbiome is acquired- that means it has a very important changeable, mutable property.
"This gives us something to work with in the clinic. If you can manipulate the microbiome you can keep a healthy microbiome healthy or re-balance an unhealthy one," she says.
But who owns the microbiomes inhabiting our bodies? And what does this mean for the regulation of pro-biotics that can change them?, asks ethicist Prof Any McGuire of Baylor College of Medicine.
These are questions that will need to be ironed out as our knowledge of this area expands, she says.
But we only have half the story. We need to find out much more about how the microbiome talks to human cells says Prof David Relman of Stanford University.
"It is still an unknown land. Even though it is on home turf we are still discovering new life forms on it," he says.

A photo purporting to show a baby whose mother was forced to have an abortion has shocked Chinese internet users.
Feng Jiamei, from Zhenping county in Shaanxi, was allegedly made to undergo the procedure by local officials in the seventh month of pregnancy.
Ms Feng was forced into the abortion as she couldn't pay the fine for having a second child, US-based activists said.
Rights groups say China's one-child policy has meant women being coerced into abortions, which Beijing denies.
National and local family planning authorities are investigating the incident, the Global Times newspaper reports.
"Feng Jianmei's story demonstrates how the One-Child Policy continues to sanction violence against women every day," said Chai Ling of the US-based activist group All Girls Allowed.
The group says it spoke to Ms Feng and her husband Deng Jiyuan after the incident. Mr Deng said his wife had been forcibly taken to hospital and restrained before the procedure.
Unnamed local officials in Zhenping county quoted in local media reports denied forcing Ms Feng to have the abortion.
"This is what they say the Japanese devils and Nazis did. But it's happening in reality and it is by no means the only case... They [the officials] should be executed," one reader on news website netease.com said, according to Agence France-Presse.
Activist Chen Guangcheng, who was put under virtual house arrest for campaigning against forced abortions, fled China to the US last month.

Gaza water too contaminated to drink, say charities

Gaza water too contaminated to drink, say charities

A Palestinian boy carries chicken waterers found in a coop as he walks over debris at the site of an Israeli air strike in Rafah in the southern Gaza Strip on 6 June 2012  
War damage is in part to blame for the dire state of Gaza's water and sewage systems, the report says
Gaza's only fresh source of water is too dangerous to drink because of contamination by fertiliser and human waste, a new report says.
The charities Save the Children and Medical Aid for Palestinians say the number of children being treated for diarrhoea has doubled in five years.
They say Israel's five-year blockade of the territory is preventing crucial sanitation equipment from getting in.
The blockade must be lifted "in its entirety", they say.
The report, Gaza's Children: Falling Behind, says that high levels of nitrates and other contaminants have been found in the main water supply.
Nitrates, found in faeces and fertiliser, are linked to the doubling of the incidence of watery diarrhoea in children since the blockade began, it says.
As well as the blockade, it blames war damage and chronic underinvestment.
Desperate families are turning to private water sources - without realising that this water too is contaminated, often at 10 times the safe level, the report says.
And Gaza's sewage system is "completely broken".
Israel insists that the blockade of Gaza has been eased considerably in recent months, says the BBC's Wyre Davies in Jerusalem.
It says more supplies and building materials to help reconstruction of the territory's battered infrastructure are being allowed in.
But the report says this is not enough.
"As a matter of urgent priority for the health and well-being of Gaza's children, Israel must lift the blockade in its entirety to enable the free movement of people and goods in and out of Gaza," it says.
It also calls on the international community, the Palestinian Authority and aid donors to do more.
