The impressive seven-window addition has already offered up stunning pictures of earth. Image […]

This project combines two of my favorite things: crayons and rockets. It may have taken John Coker 12 years to complete this project (hey, who among us hasn’t had a case of lingering works-in-progress?) but the result was more than worth it. He’s even included a step-by-step of how he made the rockets. The detail in matching the Crayola design is pretty impressive. I just want to know if he could find a way to add in that awesome Crayola smell.
Sierpinski tetrahedron By George Hart for the Museum of Mathematics A classic 3D fractal is the Sierpinski tetrahedron, which is a tetrahedron of tetrahedra of tetrahedra, etc. This fifth-order model is about 8.5 inches along its edges. It is made from nylon by selective laser sintering. If you have access to additive fabrication machines, you […]
Printing body parts: Making a bit of me @ The Economist… THE great hope of transplant surgeons is that they will, one day, be able to order replacement body parts on demand. At the moment, a patient may wait months, sometimes years, for an organ from a suitable donor. During that time his condition may […]
The Bloom Box: An Energy Breakthrough? @ 60 Minutes… In the world of energy, the Holy Grail is a power source that’s inexpensive and clean, with no emissions. Well over 100 start-ups in Silicon Valley are working on it, and one of them, Bloom Energy, is about to make public its invention: a little power […]
Along the same lines, a reader recently pointed me to this paper in the ACS journal Applied Materials & Interfaces that proposes using capillary action along ordinary cotton thread as a cheap and easy way to prototype, and perhaps even manufacture, microfluidic devices. Although the scale of even fine thread is quite a bit larger than normal for microfluidic research, the accessibility of the technique is pretty intriguing. Among other things, Wei Shen and co-workers at Australia’s Monash University demonstrate that fluids flowing along two thread “channels” can be effectively mixed simply by twisting the threads together, and that, when stitched onto an impermeable substrate, two channels can cross each other, without mixing, by the simple expedient of passing one thread over the substrate and one thread under it at the intersection.
