Introducing Magnet-Responsive Memory Foam
Roland Piquepaille writes "The U.S. National Science Foundation (NSF) has recently reported that two research teams have developed a new porous foam of an alloy that changes shape when exposed to a magnetic field. The NSF states that this new material is able to remember its original shape after it's been deformed by a physical or magnetic force. This polycrystalline nickel-manganese-gallium alloy is potentially cheaper and lighter than other materials currently used in devices ranging from sonar to precision valves. It also could be used to design biomedical pumps without moving parts and even for space applications and automobiles."
Well, such pumps do exist - you can pump liquid metals by passing a current through them, and applying a magnetic field at 90 degrees to the current as per high school physics - but I doubt they'll be pumping molten sodium through people any time soon. You could build a diaphragm pump with this approach, presumably using a two-phase magnetic circuit to very the length of the magnetic actuator, and this would probably be a lot better than passing airlines into people to operate conventional diaphragm pumps, as is done at present. But the pump has at least two moving parts, i.e. the actuator and the diaphragm.
I suspect the author meant "no rotating parts".

It will really be interesting to see where this technology will be used in, and when it reaches ordinary consumers.

To mention that production of any theorized applications will take 5-10 years. Yeesh, the editors usually remember to add that bit of useless info when they add the useless list of possible uses!

This would be cool for bumpers (I think some of the colonies call them fenders). You could park your car, shunt the other card out of the way and then apply your magnetic field and say "Nar it wasn't me, mate. Look, my car is OK. Must have been some other bloke".
I can see the commercials now...

biomedical pumps without moving partsThat should read "without rubbing parts". And even with that increased language precision, we still don't know the answer to the important question, which is whether this willow allow pumps "without fatiguing parts". (I suspect this will not be possible without biological-like microscopic self-healing.)

That's nothing. I have stacks and stacks of disks with INFORMATION that changes shape when exposed to a magnetic field.

is it time to get real yet? A LOT of energy is being squandered in attempts to keep US in the dark. in the end (give or take a few 1000 years), the creators will prevail (world without end, etc...), as it has always been. the process of gaining yOUR release from the current hostage situation may not be what you might think it is. butt of course, most of US don't know, or care what a precarious/fatal situation we're in.
for example; the insidious attempts by the felonious corepirate nazi execrable to block the suns' light, interfering with a requirement (sunlight) for us to stay healthy/alive. it's likely not good for yOUR health/memories 'else they'd be bragging about it?
we're intending for the whoreabully deceptive (they'll do ANYTHING for a bit more monIE/power) felons to give up/fail even further, in attempting to control the 'weather', as well as a # of other things/events.

meanwhile, you can help to stop the bleeding (loss of life & limb);

the bleeding must be stopped before any healing can begin. jailing a couple of corepirate nazi hired goons would send a clear message to the rest of the world from US. any truthful look at the 'scorecard' would reveal that we are a society in decline/deep doo-doo, despite all of the scriptdead pr ?firm? generated drum beating & flag waving propaganda that we are constantly bombarded with. is it time to get real yet? please consider carefully ALL of yOUR other 'options'.
the creators will prevail. as it has always been.

as there are no benefits, just more&more death/debt & disruption. fortunately there's an 'army' of light bringers, coming yOUR way.
the little ones/innocents must/will be protected. after the big flash, ALL of yOUR imaginary 'borders' may blur a bit? for each of the creators' innocents harmed in any way, there is a debt that must/will be repaid by you/us, as the perpetrators/minions of unprecedented evile, will not be available. 'vote' with (what's left in) yOUR wallet, & by your behaviors. help bring an end to unprecedented evile's manifestation through yOUR owned felonious corepirate nazi glowbull warmongering execrable. some of US should consider ourselves somewhat fortunate to be among those scheduled to survive after the big flash/implementation of the creators' wwwildly popular planet/population rescue initiative/mandate. it's right in the manual, 'world without end', etc....
as we all ?know?, change is inevitable, & denying/ignoring gravity, logic, morality, etc..., is only possible, on a temporary basis. concern about the course of events that will occur should the life0cidal execrable fail to be intervened upon is in order. 'do not be dismayed' (also from
I'd be almost equally happy if future politicians got a really good grounding in history, instead of being told that it is irrelevant.

Wow. Roland Piquepaille submitted the story, and it doesn't link to some plagiarized copy on his blog. Shocking. Could he have reformed?

First cars get seatbelts to make wrecks safer,
then airbags to make getting in a wreck fun,
now cars get memory foam so you wreck, you didnt total your car, you just ahve to press the reset button, watch the car restruct itself from the ashes. we call this model Phoenix. this reconstuctive property became necessary upon giving it flying capabilities. we had to remove the flux capacitor to fit it all in though.

Unfortunately even National Geographic is far from being impartial and is heavily skewed in favor of pandering to patriotic or other themes. This is nothing new either: they were doing this during WW2 too.
Engineering is the art of compromise.
I'd like to see some version of these electromagnetic "shape memory" materials in a cheap transparent form that can coat touchscreens. If they could be switched from smooth to a raised bump quickly, with very little power, and at high rez (about the size of a display pixel), they'd make for great feedback devices for "GUIs". Raised edges of GUI widgets, even vibrating areas indicating active buttons and their state. That would compensate quite a lot for how our fingers obscure the GUIs while we're operating them. And maybe even eliminate most of the need to actually even look at the GUI for most familiar interfaces.
If this MRMF stuff can work in a thin enough coating, maybe it could be transparent. Or just some other transparent stuff that isn't as fancy, but just jumps on command without blocking the light.

Quite irrelevantly and incidentally, this is my beef with current theoretical physics. It's substituting a defective theological argument (an infinite regress of universe constructors) with an argument that goes against Ockham's Razor (an infinity of parallel universes.) In a recent popular article on the subject I saw a suggestion that we can't see the additional dimensions because we are made of particles that are bound to only 4 of them. I am not a physicist, obviously, just a would be theologian who retrained as an engineer, but I'm beginning to suspect that String Theory is a religion, and should not be taught as science in schools.
