Meet the Spacecraft That Could Save NASA a Fortune. Somehow related with Leopold's cubesats. To my eyes, this kind of spacecraft can open the door to "cubepayload"

the google of semantic search?

It works with propellant available on Mars!!!!!

Apparently, I becomes possible to create proteins from scratch already. Things become interesting...

Theo Jansen is an artist and kinetic sculptor living and working in Holland. He builds large works which resemble skeletons of animals which are able to walk using the wind on the beaches of the Netherlands. His animated works are a fusion of art and engi

[MR] Semantic bookmarking system. Kevin, maybe You could have a look if it's worth trying?

Velcro made of steel, capable of sustaining 800Celsius.

apparently competitive with CNT and others in performance, while as you would expect very cheap. anyone know what happens to chicken feathers in a vacuum?

This is the guy of Luzy's joke: "Dear, this is not what it seems. I can explain EVERYTHING!"

yeah an interesting theory, definitely worth following. But it is far from being mature, and a lot of work remains before saying that it is viable or not... I posted something on this some time ago (http://www.diigo.com/user/pacome/horava_theory) and proposed to do smthing on it in the idea storm (our new creative game...), which didn't have a lot of success... I like also the idea of matrix gravity (see Matrix general relativity: a new look at old problems, Ivan G Avramidi, CQG 21, 103)

you are among what???

nice tool ... but apparently not open source :-(

already posted further down the page

Finally a massively multi-core general-purpose architecture.

Well, nice, but I wonder how much cache per core will be available... With 48 cores a single memory bus becomes nothing more than one big (small? :) ) bottleneck.

Apparently they have separated L2 cache per-tile (i.e., every two processors) and a high speed bus connecting the tiles. As usual, whether it will be fast enough will depend from the specific applications (which BTW is also true for other current multi-core architectures). The nice thing is of course that porting software to this architecture will be one order of magnitude less difficult than going to Tesla/Fermi/CELL architectures. Also, this architecture will also be suitable for other tasks than floating point computations (damn engineers polluting computer science :P) and it has the potential to be more future-proof than other solutions.

nice ideas ...

"And according to his calculations, improvements in short-pulse laser systems could make this form of thruster more than 40 times as efficient as even the best of today's ionic propulsion systems that push spacecraft around. "

Dejan please have a look at this also ...

while the nuclear reaction seems to be sound at first view, I am not so sure how this would work: "Electromagnetic forces push the target and the alpha particles in the opposite directions, and the particles exit the spacecraft through a nozzle, providing the vehicle's thrust. "
