Well, this carnival doesn't really have much to do with the impending end of the oughties decade, but since everybody seems to be going on about it, compiling decadal reviews and best-of lists, I just tossed it up there. Caught your eye, didn't it? But didn't turn you off, I hope... :-)
So, welcome to this (late) winter solstice edition of Scientia Pro Publica, and dig into a fair helping of hearty reading matter to keep you company by the fireside as this winter rolls you over into the double digit years of the new millennium.
Let us begin, for this is the holiday season, with some thoughts about food: about the diversity of our food sources, about how much we waste, and about how often we are hoist by our own petards in attempting to manage our precious natural - esp. food - resources. Let's start with Jeremy Cherfas, who has over the past year taken us along on the journeys of N. I. Vavilov, that pioneering explorer and champion of agricultural biodiversity. Vaviblog makes for very interesting reading indeed, especially for someone like me who doesn't know much about Vavilov. But here, Jeremy rather uncharacteristically lets loose with a rant about the difficulty of pinpointing the exact location of one of Vavilov's collections in the Sahara, and takes us through the frustrations of finding information in GeneBank and other online databases that are supposed to make the life of the modern keyboard explorer much easier than that of people like Vavilov who, you know, actually went out to the frikking Sahara in pursuit of interesting plants! Without, mind you, GPS or iPhones or laptops, as one of his commenters reminds us. Still, what's the point of all this talk about making information accessible to everyone if one can't pinpoint and georeference where Vavilov found a particular plant a century ago? I want my data instantly, don't you? Well, if you're carried away by expectations of CSI like speed in modern data acquisition, let Heilochica bring you down to earth with a (hopefully) comprehensible explanation of something complicated!
But let's stick with Jeremy a while longer and visit his another blasted weblog to read about a recent PLoS paper on how much food is wasted in America; some sobering statistics there, to be sure, plus the disquieting observation that there is no incentive in this country for anyone in the food industry to stop producing, consuming, and wasting food, environmental and human health consequences be damned! Ponder that while you tuck into the holiday treats. And if you have to bake wheat-alternative cookies because you or someone you know is allergic to gluten, Eric Olson shares a scitimes video about Celiac disease, which may be the most under-diagnosed health problem in America today (and something I'd never heard of back home in India!).
Meanwhile, we are losing the sources of biodiversity that form the basis of our food security, even as we blithely overproduce and throw away food! What's a conservationist to do to change such odd human behavior? Well, not what they did in the Pacific island nation of Kiribati, where they encouraged coconut farming as a way to lure people away from fishing in order to relieve pressures on fish stocks! Find out what happened on the Agricultural Biodiversity Weblog, in another post by Jeremy about the law of unintended consequences! Which bring me to the question from one of my own recent posts: what is it with these Pacific island nations and their penchant for such tragicomedies?
Lest you think this carnival is turning into mostly a one-man-show, let me assure you that there is plenty more that came not from Jeremy's keyboard! For instance, continuing with fishy business, here's a post that makes this one something of a meta-carnival, a Fishy Friday roundup of fish in tanks! And if you ever found yourself agreeing with Bertie Wooster's assessment that Jeeves' superior intellect was a result of a diet rich in fish, you may be underestimating his (Jeeves' not Wooster's) neuroplasticity, the subject of a fascinating interview with Michael Merznenich at SharpBrains on the applications of neuroplasticity to keep all our minds sharp even as we age.
Then there is Mama Joules with two poisonous posts: first, a disturbing one about the dangers of lead poisoning in your home, and the still high childhood exposure rate even years after lead based paints were banned in the US. Followed by a lovely introduction to venom & vomit in Tarantulas! Gotta love them.
Given the brouhaha over the climate change negotiations in Copenhagen, I'm a bit surprised at the lack of submissions about anthropogenic global warming/climate change! Perhaps we are all over-saturated with COP15 coverage? Still, there is no shortage of controversy, genuine or manufactured, when it comes to climate change, as these two posts show: a kind of curiously provocative post that suggests nuclear energy may still become part of our green energy future - safely(?) (I have a more cynical take on the subject as I think we are addicted enough to energy in our technology-dependent societies that we are near a threshold where the marginal benefit of nuclear energy will outweigh the risks regardless of the environmental consequences. But that's me being Grinchy again). Meanwhile, whatgreeninvestment.com challenges us to ignore the pseudo-controversy over climate-gate and consider the climate change problem in the framework of Pascal's wager: act as if anthropogenic climate change is real because the risks of not believing it are too great! Interesting thought that - and one that James Randi might consider, having rather startlingly fallen prey to AGW denialism in a manner worrisome to his most loyal supporters.
But, enough with the controversies and bad news. Let's celebrate the season while we still can, while there still is enough biodiversity to stimulate, delight, and challenge us. For even as we worry about losing species, we continue to discover delightful new ones, like the world's tiniest orchid that GrrlScientist (matriarch of this carnival) writes about. At the other end of the organismal size spectrum, Kevin Zelnio wonders why we don't have even larger whales? What keeps the blue whales, for example, from evolving to even larger body sizes? Not the fluid dynamic challenges of using a volkswagen sized heart to pump blood, or the constraints of depending on the tiny krill for food - but a recent paper suggests it may be that their mouths would have to be too big (may already be too big, proportionally) to keep that humongous body fed! That's why I love reading about evolutionary trade-offs and constraints, and allometry!
Let me leave you with two more posts that share the physical, emotional, and intellectual excitement of studying life on this planet of ours. Over on NCF's blog eco logic, Manish Chandi describes his unexpected delight in discovering brooding geckos and gorgeous snakes while on a short focused ethnographic research trip to Chowra island in the Nicobar archipelago. And Hielochica expresses her excitement in studying hydrothermal vents - which she considers a mysterious love-child of geology and biology! What could be more fun than that?
So have a happy and safe holiday my friends, and I wish you all a wonderful, productive new year full of many an unexpectedly delightful discovery. And don't forget to ring in the new year with the next edition of Scientia Pro Publica: issue #19 will be curated by GrrlScientist and Bob O'hara (submit entries per instructions here) and hosted at the latter's Deep Thoughts and Silliness,
