what seems to be an impressively detailed space game

> The games we write are always games with a scientific purpose (not training not educational) I'd say investigating how to get the crowd may be an important part of "science of crowdsourcing". So, an obvious example would be comparing how many participants the original ACT space mission game attracted versus a variant implemented in Kerbal and why. Easily made and easily publishable I think. But that's just an obvious example I can give on the spot. I think there is more potential than that, so would not dismiss the idea so definitively. But then, correct me if I'm wrong, social sciences are still not represented in the ACT... Perhaps an idea to revive during the upcoming retreat? ;-)

it's on sale on steam til tomorrow by the way if anyone's interested

New form of locomotion found in spiders. They say it could be used for a robot on Mars...don't immediately see how though. :)

True Marek :) The article does quote a Journal Paper though ..... published in zootaxa: a staggering 0.9 impact factor journal!! And watching the video you immediately understand why :)

I of course watched the video and have trouble sleeping since.

In case you have not seen this one yet...

Nice one, very impressive (also filming it with a drone :)! I noticed at 0:56 that the exhaust flames do travel upwards on the descent. I wonder how much of a problem this would be for the actual reusability / next flight approval?

impressive!

Looking forward to see what this amazing piece of engineering can do!

Whenever I see the complexity of fusion reactor design it makes me appreciate the simplicity of fission reactors even more. ;-D

Hope no one left their sandwich inside this time...

Origami bot!

It's really cool when it folds up, but then it's such a disappointing walk :) I also fail to see an advantage over regular robots. If you care about saving space during transportation, you could design a robot with that in mind without much sacrifice to it's locomotion capabilities.

It's cute but I've seen better from amateurs: https://www.youtube.com/watch?v=zK8OjwMdn5I

Using the angular momentum transmitted by an internal flywheel as an impulse, these cubes can move, jump, roll across the ground and climb over and around one another. They stick together using a set of small magnets, smart !

That is indeed a great way of using modular robots to build larger structures. I think we did bump into this some time back, but never really considered it much. Considering now the working group on structure assembling, I think we should add it to the list of building strategies and seriously consider it.

Apparently a spin-off company of the University of Wisconsin is developing non-magnetic motors. Maybe this could be useful for reaction wheels etc. on satellites that monitor the Earth's magnetic field... (preventing magnetic interference with sensors)

Duncan, this is one for you! - you can probably even build one in your kitchen ...

Concept animation featuring notional crew operations during NASA's proposed Asteroid Redirect Mission. Very cool video.

TED talks are so random even recurrent neural networks can do it

:D this is so good !!

my favourite sentence: "or to be able to solve the data in an astronaut a spider"

The sound track of Apolo mission. They have a full album devoted to the space race.

I wonder how free is the starting morphology.....

Nice... Now I have a lame question: after you have discovered ~500k asteroids, all moving (I assume more or less) chaotically in that asteroid belt, how do you tell one from another?

That's what I thought but when presented as a green "goo" in the video, it appears rather unordered... so I guess this is just an impression evoked by a not-to-scale presentation?

It depends... orbits can be chaotic if the orbital period is in a resonance with Jupiter, although such orbits are not stable. Such configurations tend to get disrupted pretty quickly (in cosmic terms :P) http://en.wikipedia.org/wiki/Kirkwood_gap

This reminds me: http://www.youtube.com/watch?v=ivQWJn5yrUg&feature=related

Nice. One step closer: http://www.youtube.com/watch?v=Aq5ydeWWr4A

they use invasive BCI for accessing to single neural cell on patiences with epilepsy.

why? I think they used patients with epilepsy because they already had an implants with electrodes, for other reasons. Otherwise in normal subjects they could not obtain these results. I wonder who (among normal subject) would like to have electrodes implanted in the brain....thus they use subjects that already have an implant.

well if I got it correctly then the had to cut and fizzle around in these brains ... always scaring, and then they claim that we have in our brains in single neurons abstract images e.g. of marilyn monroe . they speak even of Marilyn Monroe neurons :-) similarily his question "who is in control? are we in control of our neurons or our neurons in control of us? " ....

Powerful contrast between the two pictures!!

and yet another TO nonsense... And why always Harry Potter, dont't these darn scientists have more imagination or is their intellectual level just as low as being unable to read more complex literature than J.K. Rawling?? btw.: how about this skype session on TO, Leo?

Combine it with touchable holography (search for SIGGRAPH 2009 at youtube) and name it Holosuite 0.1.

Check it out: How hyper-reality might change our vision of the world in the future. Pretty cool

Here is a first entry for our canweuseitforspace database. Jose, apparently this invisibility cloack is not that difficult after all!!!! Watch the youtube video.....

only for the nerds who took the test and answered that they built their computer themselves...

i was about to say these guys are 300% nerds but i just saw they use windows...! fake nerds :) Anyway 5.15Ghz's not bad

oddly most overclocking products and software seem to be aimed at windows as far as i can tell. I'd guess because people usually only bother to do it for gaming?
