Cellphone epidemiology- Japan’s swine flu panopticon

mother, child and cellphoneIn response to the swine flu almost-epidemic, my government thoughtfully sent me a leaflet, advising me to steer clear of people sneezing and so on. The Japanese Ministry of Internal Affairs and Communications, however, appears to be approaching the problem from a more technological angle; this autumn, they’ll test a system that uses mobile phones to track the locations of citizens and inform them whether they’ve been in contact with a flu carrier:

The proposed system relies on mobile phone providers to constantly track the subjects’ geographical locations and keep chronological records of their movements in a database. When a person is labeled as “infected,” all the past location data in the database is analyzed to determine whether or not anyone came within close proximity to the infected individual.

The system will know, for example, whether or not you once boarded the same train or sat in the same movie theater as the infected individual, and it will send you a text message containing the details of the close encounter. The text messages will also provide instructions on specific measures to take in response.

The primary purpose of the test, which will involve about 2,000 volunteers in both urban and rural areas, is to verify the precision of GPS tracking technology, estimate the potential costs of operating such a system, and determine whether or not such a system can be put into practical use.

The first problem that leaps to mind here is that just one or two undiagnosed flu carriers loose in your city is going to throw a spanner in the works; those few errors will multiply exponentially over time.

Secondly – and channelling my tin-foil hat-wearing younger self for a moment – what a fantastically comprehensive way to monitor and control your population, should you decide you need (or want) to, and what a great excuse to coat the pill with. There’s a polical-dystopian technothriller just waiting to be written right there; just replace the word ‘infected’ with ‘subversive’ in the above quotes, and off you go.

Big Food: What to do about hypereating

lolHere’s an optimistic vision of the future, from the last page of The End of Overeating by former US Food & Drug Administration commissioner David A. Kessler, MD (available here and elsewhere; reviewed here; author interview by Stephen Colbert here.)

A change in perspective cannot be imposed with mandates, but must evolve as a social consensus. The goal is not to vilify all food and those who serve it, but to change our thinking about big food, those huge portions of layered and loaded food with little nutritional value. We need to look differently at the people and the places that serve it. When their power to manipulate our behavior becomes fully transparent, cues will lose their capacity to entice. Instead of expecting food to be served at every social and business occasion, we’ll realize that many offers of food outside mealtimes do not serve anyone’s interest.

In the future, new social norms and values will emerge, and food choices, offered in smaller portion sizes, will seem ‘right’ to us. That will be what we come to expect, and that will be what we want.

So, yes, as research for my optimstic sf story, I broke down, bought, and read this book, which is short, readable, and provocative.

Kessler’s thesis is that since the 80s, millions of Americans have been on a binge of conditioned hypereating, brought about by a food industry that knows how to get people to keep chowing down even when they’ve eaten more than enough. They do it with marketing, focus grouping, advertising, and even such childishly simple methods as making food easier to chew and swallow.

Kessler cites enough neuroscience data from human and animal experiments to put together a working hypothesis of marketing-driven food addiction. Among other things, the industry excels at creating tastes, textures, situations, and associations that rewire the brain to want more and more of certain kinds of foods. For example,

…[A]n animal that eats a combination of sucrose, chocolate, and alcohol releases the greatest levels of dopamine [a brain chemical associated with “attentional bias.”].

Not surprisingly, these foods have layers of sugar, salt, and fats — often in repeating geological layers. It’s akin to the tobacco industry’s striving to make cigarettes even more addictive. The food merchants seem to accomplish their goals more by trial and error than through pure research, but the result is plain for all to see: A serious obesity problem with, at the very least, a larger health care bill attached.

People need to take responsibility, and Kessler lays out some steps that will probably spawn a lot of self-help books (some of us can use the help). He simply asks that people watch how they feel when exposed to food or come-ons to the same, and alter their behavior accordingly. And maybe do what the French, he says, do, or at least used to do: Take your time at the table, and don’t eat between meals. Old-fashioned, and easier said than done.

He has policy suggestions, too. Some of them ought to be adopted for the sheer entertainment value of the outrage and resistance they’re likely to provoke.

  • Restaurants should list calorie counts, “by mandate, if they’re not willing to do so voluntarily.
  • Food package labels should contain percentages of added sugars, refined carbs, and fats.
  • Public education should focus a jaundiced eye on “big food.”
  • And my personal favorite: Marketing should be monitored and exposed.

Our greatest gift to future generations … would be to find a way to prevent the cue-urge-reward-habit cycle from ever taking hold.

There’s optimism for you. And there’s got to be some way to turn this into a story.

Computer memory to last a billion years

lifevsbitIn an attempt to address the problem of a digital dark age engineers at Berkeley have developed a technique called Nanoscale Reversible Mass Transport for Archival Memory that is intended to combine high bit-density and deep-time survival:

We have developed a new mechanism for digital memory storage with the potential to store data with both long lifetime and high density. Our memory device consists of a crystalline iron nanoparticle enclosed in a multiwalled carbon nanotube.  The nanotube can be reversibly moved through the nanotube by applying a low voltage, “writing” the device to a binary state represented by the position of the nanoparticle. The state of the device can then be subsequently read by a simple resistance measurement.

The abstract of the paper claims thermodynamic stability in excess of one billion years with data density of 1012 bits/in2.

Neuroscience soldiers

modern soldiersNothing says “futuristic” quite like new tools and techniques of warfare, which probably says something rather sad about our socio-cultural mindsets. Nonetheless, there’s no ignoring the fact that technological advances are changing the state (and nature) of the battlefield more quickly than ever before, meaning that military organisations the world over are looking for any possible way to get a jump on the other side.

Enter the US National Academies of Science, who were hired by the US military to assess the neuroscientific investment paths that would provide the best bang for their buck. It’s not about bigger guns and better armour any more, though; the soldiers themselves are the latest subject for improvement, be it by careful recruitment selection or wetware upgrades, or both.

Genetic testing might also enable recruitment officers to determine which soldiers are best for specialist jobs. For example, by combining psychological testing with genetic tests for levels of brain chemicals, a clearer picture of a soldier’s competencies might shine through. “We might say that given this person’s high levels of brain serotonin, they’re going to be calmer under pressure, so they might make a good sniper,” says Paul Zak of Claremont Graduate University in California, who was on the NAS panel. Alternatively, someone with low dopamine might be less likely to take risks, he says, and therefore be better suited as a commanding officer in a civilian area.

[…]

Zak emphasises that the panel was not asked how to turn soldiers into better “killing machines”, although “the whole purpose of maximising and sustaining battlefield capacity is to gain superiority over opponents”, admits Floyd Bloom of the Scripps Research Institute in La Jolla, California, who chaired the panel.

That’s not to say someone won’t try it, though. Zak’s own work focuses on the role of the hormone oxytocin in trust and empathy. If drugs were developed to block oxytocin, the effect might be to reduce a soldier’s ability to empathise with enemy combatants or civilians.

“There are lots of stories of soldiers who refuse to shoot other soldiers,” says Zak. “If you could get rid of that empathy response you might create a soldier that’s more prepared to engage in battle and risk their life.”

Um… OK. The practical benefits are obvious enough, I suppose, and if you can justify war itself I dare say you’ll not struggle to justify chemically adjusting your soldiers to be less bothered about the risk of bleeding their life out on some sand dune somewhere.

But research into easy ways to suppress empathy has worrying implications beyond the military sphere. After all, haven’t we just seen first hand what happens when people with a low empathy quotient are given control of the financial instruments that span the globe? Sure, they’re efficient and ruthless – but that’s a double-edged sword, right there. [via Scumlord Warren Ellis; image by Soldiers Media Center]

To be honest, I’d blame our erratic sense of empathy for most of the problems the world suffers currently… and while I suppose that research into oxytocin levels would inevitably throw up ways to boost empathy, that’s never going to be as financially or militarily appealing as the opposite. And of course, one must remember that the street always finds its own use for things…

High-speed photography

I’ve been a sucker for this stuff ever since seeing some grainy black and white broadcast on the Open University as a kid… remember the one where they’d photograph the droplet of paint hitting the rest of the liquid (which seems to be the only eighties TV ad that hasn’t made it onto YouTube yet)? Well, high-speed photography has come a fair way since the advent of silicon ubiquity, and as such this will be a pure eye-candy post.

There’s a few seconds of advert beforehand, but then you can watch this little hummingbird doing its hover-and-guzzle routine; there’s more details about the process (and videos, of course) over at Wired.
