British and Dutch scientists using a giant magnetic field have made a frog float in mid- air, and might even be able to do the same thing with a human being.
The team from Britain's University of Nottingham and the University of Nijmegen in the Netherlands has also succeeded in levitating plants, grasshoppers and fish.
Scientists at the University of Nijmegen in Holland have managed to make a frog float six feet (approximately two metres) in the air - and they say the trick could easily be repeated with a human.
The secret is not magic but a powerful magnetic field which overcomes the force of gravity.
The field makes the frog's atoms generate a weak magnetic force in the opposite direction.
This causes it to be repelled in the same way as like poles of two magnets.
Plants, grasshoppers and fish have been levitated by the research team in the same way.
NASA, apparently, is extremely interested in the experiment in order to be able to test the effects of weightlessness on astronauts without having to put them into space.
Easy, says team leader Dr Andre Geim.
There is no problem with putting a man by this magnetic levitation, to fly in the air. Technically we can do it with you without any problems.

And for those worried about the effects on the frog - don't worry.
He's not hopping mad - quite the opposite, in fact.

The tides and density n buoyancy . and how the whole FE keeps everything down. Everything, rock an life all are dielectric magnetic with water. Guest what makes it stronger in water...... Salt. Imagine that. Lol Amazing final proof to FE! Ty
We feel gravity as a force pushing against our bodies, in particular against our pressure sensor nerves. But with most of the molecules in its body lifted by magnetism does the frog feel weightless? If this could be scaled up to human level could we use it as a way of reducing the effect of acceleration, say in a centrifuge? In an inertial frame you feel weightless and if you release an object it floats next to you. If you were feeling weightless because of this EM field and you released a non-diamagnetic rock then you would see it accelerate away due to gravity, but if you released a similarly diamagnetic orange it would float next to you - is that a form of inertial frame-ness due to the EM field?
I can't explain weightlessness because i'm no physicist, but I assume the frog still feels gravity, it's just that the frog is being repelled from falling rather than actually floating in the air. You need movement to overcome gravity, but the frog is just simply being repelled by the magnetic fields.
This is what the great LORD says: Let my people go, so that they may worship me. If you refuse to let them go, I will plague your whole country with frogs. The Nile will teem with frogs. They will come up into your palace and your bedroom and onto your bed, into the houses of your officials and on your people, and into your ovens and kneading troughs. The frogs will go up on you and your people and all your officials.
— Exodus 8:1–4
Tl; read the whole thing.,
I have no proof, bit i believe the main cause of aging is dwindling/rotten "telomeres" a protein cap on your dna. The only cures are "extreme" exercise and blood transfusions from younger people and that electromagnetism thing the Lloyd the Ring keeps lakota about.,
I'm sorry I hurt your little frog feelings. Or grasshopper feelings. Or perhaps you are just upset that a joke went over your yellow-snowflake of a head. Why DID you call me that? I'd really like to know what you were thinking. If you were. Can you even explain it without resorting to more potty-mouth stupidity? Why are you even here commenting on a science video?
If a sufficient counter force is built up with the magnet, then it would have to have almost the same effect on the body as if no force were acting on it.
The force that pushes the body backwards during acceleration (inertia of the mass) can be removed with a sufficiently large counterforce.
Since the rejection already takes place at the cellular level, every cell of the body is repelled with the same force.
However, the magnet would still have to absorb the force with which it repels the body to its actual inertial mass (since the magnetic repulsion would be equal to the inertia of the body, the ejection would therefore simply mass 1 + mass 2).
not really, when you have a force you can't really do much to cancel it out... you can have a long tube where the passengers start at one end and while the acceleration occurs the cabin itself drifts towards the back(which is like having a 30-60-120m thick sponge/spring that tries to lessen the effects) which basically would make the time being accelerated longer but the forces that act on them smaller... problem is you can't really make it long enough to make it worth it in case of a launch into orbit for example... so yeah... or are you referring to artificially locking your brain and blood in place? which is the biggest problem in high G scenarios? if we could stop the brain from "bouncing" in our skull that would help, also the blood can leave it or create high pressure areas(even burst vessels) if we could avoid those then high G scenarios would be far less of a problem.
This must have some later effects in any biological being. There is no way that such force that is acting in all your own particles to the very core of your biological structure is not affecting you in some way. ¿Did they follow up on the frog to see any health changes?
What i dont understand is how they can use magnetic force, to levitate a frog without harming it. i mean theres not much metal in any biological being, so the force must be immence, and demand a high level of electrisity, to make that field. and unless there is unlimited power in space, using this for artificial gravity is unlikely. so im kind of confused. are they lifting this frog with the metal in hes body or am i missing some crucial information on how this work. somone, please enlighten me.
ALL material is Magnetic/Dimagnetic.
This will NEVER be harmful in anyway to cells of anything as ALL parts of an organism will receive EQUAL force in any and all directions. Because of this all cells shall remain relative to each other(They won't shift out of place)
You wont feel the effects of this either due to the same reason.
Now the chance that you were near a neutron star(Most magnetic Objects;Core of dead star that has a extreme magnetic field) the story is different. You will actually die due to it, reason being(And dont quote me on this) is because the magnetic field acts on your body similar to gravity, it WILL crush you. If thats not the case it will defiantly mess with your nervous system.
the GBO gamer, what other arbitrary things are you proud of? Being a certain colour because people of that same colour achieved something? Having a certain haircut because someone with that haircut achieved something? Are you extremely proud to be a person that likes the taste of tacos because someone who also likes the taste of tacos built a rocket or something? Where does this meaningless pride end? It just doesn't make any logical sense. (Unless you're the leaders of a country trying to indoctrinate the masses with patriotism)
the GBO gamer, he specifically said *this video* makes him proud to be dutch. The fact that some random scientists he's never seen before made a frog float makes him feel proud to be dutch, because they happen to be dutch. That's ridiculous and doesn't make any sense!
the GBO gamer, you just said a whole bunch of nothing.
The point of pride is to feel good about having a relevant link to an achievement.
If you personally make a frog float, then you rationally feel pride as you've achieved something.
If a close friend who you've supported makes a frog float, then you rationally feel pride as you've contributed to something.
If your child makes a frog float, then you rationally feel pride as you've contributed to that.
If some completely random strangers you've never even met or heard of before, who just happen to have been born into the same country as you, make a frog float, there's no rational reason to feel pride over it as you've had no contribution whatsoever to the thing that was achieved.
Imagine being randomly assigned to a group on a project, but you never turn up or do anything and no one there even knows you or that you're supposed to be on their team.
If you stumble upon their good project and exclaim "I feel so proud to be part of X team! :3" everyone is going to rightly think you're a delusional ass.
the GBO gamer, again with the ad hominems. They don't make you sound any better.
And I enjoy criticising opinions and having my own criticised. Heated debates are a joyful past time for me and they also educate me if someone proves me wrong. I've learnt a lot by simply discussing in internet forums and comment sections. That's the point of my comment, so there's nothing "sad" about it.
If you don't want to actually have a discussion, why are you commenting? To throw insults at someone simply commenting their opinion on an internet comment section seems like the only "sad" thing here.
As for "you're the type of people who ruin simple things for the sake of looking smarter or superior to some1" It has nothing to do with looking smarter or superior, I think the kind of people who want to feel smarter or superior are the one's who isolate themselves from other beliefs and surround themselves with conformation of their own beliefs. Not those that directly reply to people with opposing opinions looking for a rebuttal.
And if it wasn't for people like me over the centuries, people that annoyingly provoke and criticise even what seems mundane and normal, we'd be living in an extraordinarily backwards society.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
