  • The secret, social lives of bacteria – Cooperative behavior between bacteria, both inter and intra species, coordinated via chemical messages. Behavior like "should we make light?" and "should we kill the host now?". Scary, awesome, and a beautiful system to investigate with algorithmic game theory! (tagged: cooperation biology technology bacteria science )
  • Computational Legal Studies – More people using machines to understand politics. A whole new class of dual use technology. Propaganda or transparency? Manipulation or clarity? Unauthorized social networking. (tagged: transparency technology government law )
  • Public Private Investment Partnerships a la Enron – Giving banks the ability to both buy and sell into the toxic asset markets being set up under PPIP is a recipe for market gaming in the tradition of Enron, as outlined in this example. Great, a trillion dollar Enron! (tagged: finance bailout economics policy enron ppip banks )
  • The New Nostradamus – Bruce Bueno de Mesquita uses large game theory simulations to try and predict the outcomes of complex negotiations involving many parties, both economic and political. Sounds interesting. Also sounds a little bit like bullshit. But apparently the CIA did a prospective trial (no backtesting bias) and found that the models made accurate predictions something like 90% of the time, when the analysts providing the inputs to the model made wrong predictions. Not so surprising that computers are better at synthesizing massive logical datasets into an outcome. The hard part seems like it would be getting the right inputs, and also trusting that people behave rationally, and (perhaps) know what's good for them.

  • Ice Shelf Instability Backgrounder – A good backgrounder from last summer on the Wilkins Ice Shelf (which has just collapsed), and shelf dynamics in general, with links to the relevant literature. None of this is quite as sudden and shocking as the media reports have made it out to be. (tagged: climate antarctica ice shelf )

  • Sing a dirge for the unused adipic acid – An essay on the unpleasantries of being lab safety officer, and the sentimental attachment that scientists have to their expired reagents. (tagged: science chemistry lab safety )
  • Does carbon-eating cement deserve the hype? – A process for manufacturing cement which sequesters CO2 (instead of releasing it) has been recently hyped. Chemistry looks dodgy though, and the company (Calera) is not forthcoming with details, or even a gross inputs/outputs for their miracle black box. Caveat emptor. (tagged: carbon climate technology cement )
  • Self Irrigating Planter Resources – A nice little gathering of pointers to information on DIY self-watering planters. Still trying to figure out how one might be able to use tires to make one of these…. (tagged: gardening technology food sustainability urban )
  • The Case Against Breast-Feeding – Backlash against the relatively new social imperative (in the west) that women must breastfeed to be good mothers. I think the real issues are that we haven't structured our society and its expectations to meaningfully accommodate having children and equitable peer spousal relationships. I agree there's something broken, but I don't think it's breastfeeding. And I feel like it's another example of the Newtonian hangover… we're so used to being able to figure things out authoritatively, a la Newton, that we almost don't know how to deal with planning around and purturbing complex systems like the climate, or ecologies, or economies, or agricultural systems, or genomes, or nutrition… which we depend on, but don't understand fully (and because of their chaotic nature, may never understand fully. We're used to Apollonian systems, but actually we live in a Dionysian world. (tagged: science food children health breastfeeding society )
  • Collapse Of The Ice Bridge Supporting Wilkins Ice Shelf Appears Imminent – This ice shelf is 3x the area of Rhode Island. It's already floating, so it won't have any effect on sea level as it separates, but that's a lot of ice. Wish we had better time series for this kind of observation. Really need the best long term Earth monitoring system we can build. (tagged: environment climate antarctica ice )
  • The strengths of the academic enterprise – A great essay by Dijkstra on the nature of academia, and the problems of cooperation between entities with dramatically different time horizons. Who knew he was interested in things other than graph theory? (tagged: academia science sustainability education technology )

  • Stealing Commodities – Our infrastructure is (unwittingly) built around the assumption that the materials it is composed of are, and will remain, cheap, and not worth the trouble of stealing. If this assumption breaks down, copper power lines start disappearing from the desert, and iron manhole covers begin to vanish in the night. Problematically, the raw materials (even when valuable) are still only a small fraction of the value of the infrastructure, meaning replacement costs are high. If commodities were to remain "expensive" in the long run (i.e. worth stealing), how would we re-design our infrastructure systems? (tagged: sustainability economics security infrastructure commodities )
  • Dyson as Sociologist? Death Trains, Values, & Climate Action – Not sure I know quite what to make of Nisbet's take on Dyson. I agree that the catastrophe narrative is dangerous, and much prefer Richard Alley's precautionary point of view, but I really think Dyson is catastrophically wrong on this, and potentially dangerous as a figurehead, whether knowing or unknowing. (tagged: climate science policy propaganda politics )
  • Argentine economics and maker culture – An interesting and personal look at mass production vs. local/handmade goods based on currency strength and protectionist trade barriers. Where labor is cheap, the food and goods are often unique. Where it's expensive, you get mass production. Makes me want to bike S. America. Again. (tagged: economics argentina local money food )
  • China Out to Dominate in Electric Cars (and Why Not GM) – A short chronicle of GM's missteps toward electric vehicles, and China's long view of the same. Honestly, I don't care much who does the dominating, so long as somebody gets this market going. (tagged: cars transportation technology economics china )
  • Oregon’s mileage tax experiment – If you can imagine an America in which vehicle fuel economy increases with time (despite the fact that our national fleet today gets the same mileage as a Ford Model T), then eventually, funding road maintenance with a gas tax becomes a problem. Instead of taxing the fuel, you need to directly tax the road usage – miles driven, normalized by some kind of wear-and-tear factor for a given vehicle. Thus, the idea of a VMT (vehicle miles traveled) tax. Political suicide, you say, but it worked in this (politically insulated) trial in Oregon, and is going ahead gangbusters in the Netherlands and other nations, coupled with GPS enabled congestion charging, and time/location dependent parking fees, it could go a long way toward making personal transportation costs transparent and efficiently priced.

  • A New Way Forward – Grassroots banking policy? Who'd have guessed? Their plan is "Nationalize. Reorganize. Decentralize." The N-word has some bad connotations, but what they're really advocating for is an FDIC style managed bankruptcy, i.e. letting the banks fail, cleaning out the shareholders and management, and applying real anti-trust laws to the financial industry. I never thought I'd go to a banking protest. (tagged: economics bailout finance fdic activism banking policy )
  • MailStopper – Is $20/year too much to pay to avoid junk mail? Would it really work? The self-monitoring aspect is interesting too. Would be great to be able to watch your name and address as it propagates through the ocean of direct marketing databases, and credit reporting agencies. (tagged: green junkmail sustainability internet )
  • YellowPagesGoesGreen.Org – I hate the two kilograms of cellulose that the phone company insists on littering my doorstep with each year. I was a little bit drunk when they showed up last week, and threw them in the street. I don't even have a land line. Why would I want a phone book? Who uses those things anyway? Thankfully, someone else has already created an opt-out system… too bad I'll have to wait a year to see if it actually works. (tagged: environment recycling paper yellowpages mail green sustainability )
  • The Age of Stupid – A new combination sci-fi documentary on climate change… framed as a man looking back and trying to understand why we failed to act, from the year 2055. The movie was "crowd funded" – the filmmakers sold shares of the profits to individuals (and the crew) in exchange for cash (about $1 million total). The trailer looks fairly good… (tagged: climate film green environment )
  • Mistrial by iPhone – Juries’ Web Research Upends Trials – Another example (cf death of record companies, newspapers) of technology upending previously stable social and legal systems. 9/12 jury members found to be doing research on the trial they were sitting on, via their cell phones and the internet. People don't consider the meta-brain to be a separate entity any more. Certainly not for weeks of sequestration on end… (tagged: law technology internet phone jury trial )

  • The Missing $1,000,000 Tax Bracket – There's a fair amount of debate over what the "top marginal tax rate" should be, but it's infrequently noted that there's actually vastly more variation in the income threshold at which that rate becomes applicable. In inflation adjusted dollars, it's fluctuated between around $80,000 (Regan) and $80,000,000 (!) during the Depression. Ignoring this while debating the highest income tax rate is kind of absurd.

  • True Traffic Tales – Ah, bikes and cars living harmoniously together. (tagged: cartoon bicycle transportation )
  • Evangelical Climate Initiative – A Christian take on climate change, given its reality, what is the appropriate response for a conscientious person of faith? From my point of view as an atheist, it's not so important what other peoples' motivations are for taking action, as long as they take action. I'm curious how this has been received by the evangelical movement. (tagged: religion climate science christian green )
  • Sailfish Cooperating to Hunt Sardines – I had no idea sailfish were so colorful (and changeable), let alone this cooperative. Glad National Geographic still exists, even if our maps no longer have "Terra Incognita" on them (tagged: fish cooperation nature )
  • Communicating the Second Premise: Whether Obama or Bush, Values Drive Science Policy Decisions – A good look at the division between science facts/findings and science policy in the context of stem cell research and Bush's vs. Obama's take on it. Facts alone do not imply any "shoulds". We need values to tell us what's right or wrong. Sometimes those values are so obvious we don't even think about them, and sometimes they're not, especially when new and poorly understood technology is involved.
