At the moment the coming space plane uses a conventional rocket, and they are finicky beasts. Something tells me that somewhere down the line somebody is going to suggest replacing the rocket with a plasma jet engine on the grounds that it would be more reliable and to some extent more powerful. And even better, capable of reaching higher orbits. That would make launching satellites much easier.
Scientists have assembled a kind of organic circuit board for living computers by building logic gates within cells.
This looks interesting. Though at the moment I expect that the parties involved are limiting themselves.
You’ll note that what researchers have done is get the cells to sort of behave like electronic computers because electronic computers is what they understand. Yet our cells already form networks – with neurons forming the most advanced, and share information amongst themselves.
The article talks about getting our cells to do things they don’t presently do, but what if we don’t need to get them to act like computer circuits to get them to act the way we want? What if what we need to do is to encourage them to do what they already do, only better?
What I think we have here is an example of timidity, when what we need is to be daring.
A lightweight, comfortable jacket that can generate the power to light up a jogger at night may sound futuristic, but a materials scientist could make one today. In a new paper, she and colleagues outline a way to apply breathable, pliable, metal-free electrodes to fabric and off-the-shelf clothing so it feels good to the touch and also transports enough electricity to power small electronics.
I really don’t have anything to say about it – maybe later – but I thought you’d like to know about it.
