How Canadian researchers reconstituted an extinct poxvirus for $100,000 using mail-order DNA | Science | AAAS
This is kinda bad, but it was known that this was going to happen eventually. The mail order DNA/protein synthesis companies do screen the orders, but small enough fragments spread out over enough companies would evade detection. Now all it takes is a reasonably well educated individual (read bioengineering grad student), and oh hey, a certain class of extremists tend to originate from engineering backgrounds due to a black/white worldview and then...

Airlight - Home
Oddball mix of inflatable mirror/lens assembly mounted on a lightweight fiber reinforced concrete frame. Essentially makes a closed, slightly pressurized container for the energy production components, to protect them from rain and air contamination. Though the ETFE film getting discolored due to age/exposure reducing power output might be a problem. The collector is universal, in the sense that the central core receiver can be either the CSP type using pressurized air for the heat transfer fluid (which nominally gets dumped through a gravel tank for heat storage), or a water cooled CPV receiver. Recently did work with IBM using IBM chip semiconductor manufacturing techniques to make CPV water cooled solar cell panels with integrated cooling in the silicon.via microchannels.

Open source house design building blocks, with the intention of parts being CNC milled for DIY assembly. Current it seems to be about milling stuff from wood or plywood for flatpack transport for semi-custom shapes then putting various modules together, but the probable end goal is 3D contour crafting concrete structures though.

Like Michelin's Active Wheel, this incorporates a hub motor with regenerative braking and active suspension, integrated steering is interesting.

Batteries charge very quickly and retain capacity, thanks to new structure | News Bureau | University of Illinois
Interesting, using Styrofoam beads as a temporary lattice building framework to make a metal lattice, which is later covered with the final thin film. This creates a very high surface area, allowing super fast charging. But, still like SCiB batteries, it seems the energy density is lower than conventional electrode batteries of the same type (around 75%) . A worthy flaw to allow fast charging? But that doesn't get around the high amperage issues of fast charging, and there is the scary part about fast accidental discharge, so you face the same issues as ultracapacitors.

Asiajin » Soldering Cafe To Be Opened At Ex-school Site In Akihabara
I hope this turns into something like that nice shared workshop service in California called TechShop (an open access public workshop), where you have access to big boy toys like laser cutters. Maybe get one of those new laser metal sintering 3D printers in there too.

Technology Review: Making Carbon Nanotubes into Long Fibers
Generic long nanotube fibers which can scale to hundreds of meters now possible. Only problem is the process to spin fiber for conductive applications, such as transmission lines, requires very high purity source metallic carbon nanotubes. That's the other big problem of production, as there is still work to do to do mass separation of bulk nanotubes into metallic and semiconductor types at high purity .
