George Church wants to automate evolution, in the same way that we’ve now automated genome sequencing. Any trait that can be easily and automatically screened for should be susceptible to the technique. You give the machine a rough draft, and let it mutate the genome in fast forward, and iterate with screening/selection. They’ve already used the technique to engineer a couple of pigments (indigo and lycopene) much more effectively than straightforward genetic designers. Mmm. Custom evolved babies. And virus-proof replacement livers. Sweet, in a creepy kind of way.

Womb for Rent
Surrogate pregnancies are becoming common in India. For roughly the cost of having your own baby in the US healthcare system, you can outsource the task of giving birth to a Gujarati woman. It sounds like there’s a wide range of conditions, some less ethical than others. Is it okay to pay someone the equivalent of 10 years worth of wages to bear your child, so that they can give their daughters good dowries? The mind boggles. How long until you just upload the two genomes you’d like intertwined, and pick up the baby at the airport 9 months later? Or even better, maybe someone could take care of them in a well organized creche until about age 5, when they’re all potty trained and interactive. Choose from our vast selection of native languages and cultural indoctrination schemes! All the benefits of having kids when you’re 25, without the negative career impacts. Operators are standing by.

- Where can you get Cheap Natural Fertilizers and Soil Amendments? – A nice concise list of natural sources for garden nutrients, when your compost pile just isn't quite enough. (tagged: gardening food organic fertlizer compost biology )
- Pinko bastion spawns capitalist solution to solar financing – Boulder city/county passed the same kind of property-tax based financing of energy efficiency (and solar) improvements on the Nov. ballot too – modeled on Berkeley, but with enabling legislation at the state level (to avoid the kind of lawsuit Berkeley had to fight over whether or not they had the power to issue such bonds). The biggest worry I had in reading the Boulder initiative though, was that they had not yet come up with a good mechanism for ensuring that the improvements which were being proposed (more insulation, solar hot water, whatever) would necessarily save enough energy in order to justify the value of the bond being created. Hopefully they’ve fleshed that metric of value out much better by now (in both Boulder and Berkeley) and it’s not possible to abuse it… otherwise I suspect you’ll get deployment of faddish fixes (e.g. sexy-sexy PV instead of solar hot water, or better insulation, or super-windows, etc) instead of the best energy improvement per dollar invested.

- Campaign for a Car-Free Lincoln Park, Pt. 2 – A lack of car-free options for arriving at Lincoln Park, coupled with poorly lit, unsafe parking far away from the park's main attraction means everyone just drives their cars all over the park, on the grass. Across the street, the DMV has a huge parking lot which is totally unused after business hours, which is when the park gets the overwhelming majority of its use. Why not (gasp!) timeshare the DMV lot? Hopefully no small children have to get crushed by the marauding death machines for someone in the state and city government to take this idea seriously.

- FlyingConcrete – Beautiful biomimetic architecture. Curving vaulted ceilings and stairways. Rounded sleeping nooks and pillars like trees. Traditional rectilinear construction is so boring. This is lightweight concrete (cement with perlite, pumice, and other lightweight filler added instead of sand and gravel) laid up on a mesh that's been shaped such that when the cement hardens, it's a load bearing compressive structure. (tagged: architecture art concrete design construction buildings sculpture )
- Drew Endy and Jim Thomas Debate Synthetic Biology – An unusually good discussion about the future of biotechnology, and maybe the only time I've ever really seen the "debate" format work, and elicit relatively thoughtful interaction. I think they're both dancing around the fundamental question though, of to what extent (if any) society even *gets* to make a choice on this topic.

The holes in my woolens
I discovered a couple of small holes in one of my my merino sweaters this morning. Moth larvae. My fault for not using camphor or some other kind of deterrant. At first, I was bummed because I thought this represented a flaw – I love wool, and especially merino, because it’s warm even when it’s wet, it wicks, it doesn’t smell, it doesn’t burn and melt like plastic, it’s durable and comfortable and not based on petrochemicals. But moths can eat it, and it can mold. It requires more care than fleece. Thinking just a little more, it occurred to me that actually, these holes are in some sense a feature, not a bug.
