A malaria parasite within a human red blood cell. The large circle in the parasite is a food vacuole. Stacked heme are visible inside the vacuole. Researchers at the University of Washington have discovered a method of treating malaria with magnetic fields that could prove revolutionary in controlling the disease the World Health Organization calls one of the world’s most complex and serious human health concerns. Henry Lai, UW research professor of bioengineering, says the malaria parasite Plasmodium appears to lose vigor and can die when exposed to oscillating magnetic fields, which Lai thinks may cause tiny iron-containing particles inside the parasite to move in ways that damage the organism. “If further studies confirm our findings and their application in animals and people, this would be an inexpensive and simple way to treat a disease that affects 500 million people every year, almost all in third-world countries,” Lai said. According to the World Health Organization, as many as 2.7 million people die of malaria every year. Approximately 1 million of those are children. In the past two decades, the emergence of drug-resistant malaria parasites has created enormous problems in controlling the disease. Lai says his method could bypass those concerns because it is unlikely Plasmodium could develop a resistance to magnetic fields. Malaria is spread by female Anopheles mosquitoes. The organism first invades the liver, then re-emerges into the bloodstream and attacks red blood cells. This is what causes malaria’s hallmark symptoms: fever, uncontrolled shivering, aches in the joints and headaches. Infected blood cells can block blood vessels to the brain, causing seizures and death. Other vital organs are also at risk. Lai’s research appears to take advantage of how the parasites feed. Malaria parasites “eat” the hemoglobin in red blood cells of the host. They break down the globin portion of the hemoglobin molecule, but the iron portion, or the heme, is left intact because the parasite lacks the enzyme needed to degrade it. This causes a problem for the parasite because free heme molecules can cause a chain reaction of oxidation of unsaturated fatty acids, leading to membrane damage in the parasite. The malaria organism renders the free heme molecules non-toxic by binding them into long stacks - like “tiny bar magnets,” according to Lai. He and three other researchers have exposed Plasmodium falciparum, the deadliest of the four malaria parasite species, to a weak alternating, or oscillating, magnetic field. Data sets showed that exposed samples ended up with 33 to 70 percent fewer parasites than unexposed samples. Measurements of hypoxanthine, a precursor for nucleic acid synthesis used by the parasite, indicated that metabolic activities had also significantly slowed in exposed samples. Such reductions would be enough to manage malaria, Lai said. The oscillating magnetic field may affect the parasites in two ways, according to Lai. In organisms still in the process of binding free heme molecules into stacks, the alternating field likely “shakes” the stacked heme molecules, preventing further stacking. That would allow harmful heme free reign within the parasite. If the parasite is further along in its life cycle and has already bound the heme into stacks, the oscillating field could cause the stacks to spin, causing damage and death of the parasite. Although initially promising, Lai says more research is needed. “We need to make certain that it won’t harm the host,” Lai said. “My guess is that it won’t. It’s a very weak magnetic field, just a little stronger than the earth’s. The difference is that it is oscillating.” If the method is proven effective and safe, Lai envisions rooms equipped with magnetic coils to produce the oscillating field. “It would be very easy. People could come to the room and sit and read or whatever while they’re being treated,” he said. “Or you could set it up in the back of a big transport truck, then drive from village to village to treat people.” Collaborating researchers include Jean E. Feagin, UW associate professor of pathobiology and senior scientist at the Seattle Biomedical Research Institute; and Ceon Ramon, UW electrical engineering research scientist.

Fascinating video - thank you. I had a play with different thickness screwdrivers in my 'Magnetiser/Demagnetiser'. It seems that for thin bladed screwdrivers, I needed to use the stairs to successfully demagnetise. If I use the lowest stair, then the screwdriver is still able to pick up ferrous materials. Using a higher step successfully removes the magnetic field. I was able to repeat this several times. I guess thin materials saturate more easily, so need to be demagnetised in a weaker field, hence using the staircase.
@Br3ttM2 жыл бұрын
Magnetic materials kind of short circuit magnetic fields, so it would make sense that a weak magnet would still be able to saturate a thin object, because there is less diameter to spread the field inside the object.

I think the steps in the demag may actually have a function. Since there is a magnet on only one side of the demag window, the field gets weaker the further up you go. Some alloys, with certain BH magnetization curves may need a very specific strength to rotate their magnetism at right angles to the length, but not pull the field out the end of the device, as you remove it. The steps give you several choices of demag field strength to choose from. With your fancy field meter, you should be able to find the step that produces the minimum lengthwise magnetization of various objects.

Magnetic materials are magnetic at an atomic level, and form tiny regions of aligned magnetic fields the same way they form crystals when becoming solid. All the tiny magnetic regions cancel out normally, but they can be rearranged to align. Demagnetizing something means removing that alignment in some way, either using other magnets to change them, or heating them until they lose their magnetism, in which case they get their random grains again when they cool.

Very good video. The stairs actually have a purpose: if you start with the lowest and do one for each step, you will demagnetize it almost completely. If you just do the lowest one, then you will retain a little bit of magnetization (although not enough for your test--it will show up if you test with something small like iron filings). This is because, as you show in your video, the magnetic field lines are more and more perpendicular to the screw driver the further you move up the stairs. Of course, as you say, they don't actually "do" anything, so you could just repeat the motion without them.

@@Xnoob545 and @HULL GUITARS USA @Xnoob Speakable is thinking in the right direction. The explanation that was given when it was demonstrated to me, is that in ferromagnetic materials, the magnetic domains usually are in disarray. When you magnetize them, you arrange their magnetic polarities in one direction, such that enough of the magnetic domains align in the direction of the applied magnetic field to make the material magnetic. Then when you drop the screwdriver, the impact makes most of the magnetic domains snap back into their natural position, which cancels their previously induced orientation. I don't know for certain if this explanation holds any water, but you can easily verify that de-magnetizing a magnetized screwdriver by dropping it, works.

Very impressive. For decades, I thought that stroking a piece of steel with a magnetic pole would magnetise it, and the way to demagnetise it was to place the magnet in an alternating magnetic field and then removing it. Here is proof that a bar magnet can be used to demagnetise a magnet if the bar magnet is placed PARALLEL to the magnetic axis of magnet and stroked. That way the magnet is subjected to decreasing magnetic field strength in a varying direction. Brilliant! Thank you.

I have one of these. I tried to demagnetize my calipers because they were picking up a whole lot of metal dust and schmoo, but it didn't work. I guess I have the wrong pole configuration. Thank you for making this video, it cleared a lot of things for me.

Very interesting video! If I had seen this a year ago I wouldn't have had to saw open a magnetizer / demagnetizer to see how it worked. But it is also still usable when sawn open. The inner workings are surprisingly simple and ingenious.

Correct English is when "sawn" open not "sawed". He sawed through the plastic, the plastic was sawn open, he used a saw to saw through the plastic which had been previously sawn. Sore is when you cut your finger when sawing.

Can you polarize other metallic objects with other polarized objects ? If yes, I guess that the polarizing will be weaker and weaker ? Maybe a subject for another video :)

this is a great way to demonstrate how it works. Perhaps you like to demonstrate how welding-magnets and/or lifting (permanent) magnets with the switch-off options as well in this way. I would like that a lot! Thanks!

The stairs are so you can remove only a small amount of magnetic pull to adjust the level of force you want. Helps when working with small screws
@aimanyusof8863 Жыл бұрын
Why do you want different forces for different screws? Sincere question.
@markylon Жыл бұрын
@@aimanyusof8863 Well a small light screw doesn't need the same power of magnetism as a large heavy screw.

During my internship I used a de-magnetizer tool to get rid of static in spatulas so I could weigh small amounts of test compounds without it sticking to the metal spatula. It was an electric device consisting of two vertical prongs. You pass it through when its on and boom- it's no longer static. We called it the Harry Potter device. Do you think it could be the same principle, except the base is an electromagnet?

Mind blown. I have one of these (somewhere...) and recall failing to get it to work well. But this is insultingly simple 😂 Thank you for putting us to shame, whilst explaining very clearly! P.S. Mine doesn't have the rounded corner to the "demagnetise" cavity, but does have the steps (which seem plausibly explained in other comments here). I feel enlightened.

Your cutlery and screwdrivers look really attractive
@amyshaw8932 жыл бұрын
I think that regarding the intro, your cutlery being magnetic isn't because you use lots of magnets. My parents cutlery is slightly magnetic too, and they don't use lots of science things. I seem to remember reading somewhere that rubbing metal together (like rattling in the drawer or normally using them) slowly magnetises it, but I am unsure of the science of that
@startedtech2 жыл бұрын
I just did some googling on that, the answers I got were related to dishwashers. It's either the heat when they're aligned a certain way, or a poorly shielded motor creating a magnetic field that affects it. Or both.
