Researchers Uncover How A Nanoscale ‘Compass’ Inside Bacteria Orients Them To The Earth’s Magnetic Field

ScienceDaily (Nov. 21, 2005) — It is not only migratory birds that orient themselves to the magnetic field of the Earth. Also bacteria — supposedly “simple” organisms — have evolved to be able to take advantage of the magnetic field in their search for optimal living conditions.

Such “magnetotactic” microorganisms use a miniature, cellular compass made of a chain of single nanomagnets, called magnetosomes. The entire bacterium is oriented like a compass needle inside the magnetic field. Until now, it was not clear how the cells organise magnetosomes into a stable chain, against their physical tendency to collapse by magnetic attraction…

Oceans charge up new theory of magnetism

A radical new idea may revolutionise our understanding of one of the most vital forces on Earth

 Jonathan Leake

Earth’s magnetic field, long thought to be generated by molten metals swirling around its core, may instead be produced by ocean currents, according to controversial new research published this week.

It suggests that the movements of such volumes of salt water around the world have been seriously underestimated by scientists as a source of magnetism.

If proven, the research would revolutionise geophysics, the study of the Earth’s physical properties and behaviour, in which the idea that magnetism originates in a molten core is a central tenet.

Earth’s magnetic field is vital for life, extending tens of thousands of miles into space and protecting the planet against radiation that would otherwise burn away the atmosphere and oceans.

However, its origin was a mystery until early last century when Albert Einstein said understanding the phenomenon was one of science’s most important tasks. This provoked a debate which concluded with scientists agreeing that magnetism must originate in the Earth’s core.

“Everyone accepted this, but in reality there has never been any proof,” said Gregory Ryskin, associate professor of chemical and biological engineering at Northwestern University in Illinois. “It is just an idea we have accepted for a long time without questioning it enough.”

His research suggests that Earth’s magnetism is actually linked to ocean movements. The salt in seawater allows it to conduct electricity, meaning it generates electrical and magnetic fields as it moves.

The findings, published by Britain’s Institute of Physics’s New Journal of Physics, will cause a fierce scientific debate.

Existing theories explain Earth’s magnetism by suggesting that the centre of the planet comprises a white-hot solid iron ball about 1,500 miles in diameter, surrounded by an outer shell of liquid metal a further 1,400 miles thick.

As the liquid iron in that shell is heated by the inner core it becomes less dense and rises upwards, to be replaced by cooler material from above.

The resulting swirls of molten metal create electric currents that in turn produce the planet’s magnetic field, the conventional theory suggests.

The big problem with this idea is that it is almost impossible to obtain experimental evidence because the Earth’s core is so inaccessible. Indirect approaches, such as computer modelling, have thrown up many inconsistencies.

Ryskin approached the problem differently, by looking at the way Earth’s magnetic field undergoes constant changes, growing stronger in some regions and weaker in others. This phenomenon, known as variation, also sees gradual shifts in the locations of the north and south magnetic poles.

Scientists have always linked variation with turbulence in the outer core, but Ryskin suggests it actually correlates with changes in ocean circulation. In the north Atlantic, for example, changes in the strength of currents were matched by sharp changes in magnetic fields.

One idea is that changes in ocean circulation may explain the curious reversals shown by Earth’s magnetic field, in which the north and south magnetic poles suddenly flip over. This last happened 780,000 years ago.

This could also be linked to tectonic plate movements that have shifted the world’s land masses around the globe, forcing ocean currents to adopt entirely new routes.

If Ryskin is right, then climate change, predicted to alter the strength and course of ocean currents, could also alter the planet’s magnetic field.

Ryskin emphasises that such suggestions need much more research, but some other physicists have been quick to recognise its implications. Raymond Shaw, professor of atmospheric physics at Michigan Technological University, said it could make “the ruling paradigm of geophysics irrelevant”.

Bacteria magnetic feild lines

The image shows the magnetic field lines in a single bacterial cell. The fine white lines are the magnetic field lines in the cell, which were measured using off-axis electron holography. Such bacteria live in sediments and bodies of water, and move parallel to geomagnetic field lines as a result of the torque exerted on their magnetosome chains by the earth’s magnetic field.

Science is learning more about strange world of magnetic feilds, from the article “Magnetic Portals Connect Sun and Earth” on the NASA website:

Oct. 30, 2008: During the time it takes you to read this article, something will happen high overhead that until recently many scientists didn’t believe in. A magnetic portal will open, linking Earth to the sun 93 million miles away. Tons of high-energy particles may flow through the opening before it closes again, around the time you reach the end of the page.

“It’s called a flux transfer event or ‘FTE,’” says space physicist David Sibeck of the Goddard Space Flight Center. “Ten years ago I was pretty sure they didn’t exist, but now the evidence is incontrovertible.”

Indeed, today Sibeck is telling an international assembly of space physicists at the 2008 Plasma Workshop in Huntsville, Alabama, that FTEs are not just common, but possibly twice as common as anyone had ever imagined.

Researchers have long known that the Earth and sun must be connected. Earth’s magnetosphere (the magnetic bubble that surrounds our planet) is filled with particles from the sun that arrive via the solar wind and penetrate the planet’s magnetic defenses. They enter by following magnetic field lines that can be traced from terra firma all the way back to the sun’s atmosphere.

“We used to think the connection was permanent and that solar wind could trickle into the near-Earth environment anytime the wind was active,” says Sibeck. “We were wrong. The connections are not steady at all. They are often brief, bursty and very dynamic.”

Several speakers at the Workshop have outlined how FTEs form: On the dayside of Earth (the side closest to the sun), Earth’s magnetic field presses against the sun’s magnetic field. Approximately every eight minutes, the two fields briefly merge or “reconnect,” forming a portal through which particles can flow. The portal takes the form of a magnetic cylinder about as wide as Earth. The European Space Agency’s fleet of four Cluster spacecraft and NASA’s five THEMIS probes have flown through and surrounded these cylinders, measuring their dimensions and sensing the particles that shoot through. “They’re real,” says Sibeck.

Now that Cluster and THEMIS have directly sampled FTEs, theorists can use those measurements to simulate FTEs in their computers and predict how they might behave. Space physicist Jimmy Raeder of the University of New Hampshire presented one such simulation at the Workshop. He told his colleagues that the cylindrical portals tend to form above Earth’s equator and then roll over Earth’s winter pole. In December, FTEs roll over the north pole; in July they roll over the south pole.

Sibeck believes this is happening twice as often as previously thought. “I think there are two varieties of FTEs: active and passive.” Active FTEs are magnetic cylinders that allow particles to flow through rather easily; they are important conduits of energy for Earth’s magnetosphere. Passive FTEs are magnetic cylinders that offer more resistance; their internal structure does not admit such an easy flow of particles and fields. (For experts: Active FTEs form at equatorial latitudes when the IMF tips south; passive FTEs form at higher latitudes when the IMF tips north.) Sibeck has calculated the properties of passive FTEs and he is encouraging his colleagues to hunt for signs of them in data from THEMIS and Cluster. “Passive FTEs may not be very important, but until we know more about them we can’t be sure.”

There are many unanswered questions: Why do the portals form every 8 minutes? How do magnetic fields inside the cylinder twist and coil? “We’re doing some heavy thinking about this at the Workshop,” says Sibeck.

Meanwhile, high above your head, a new portal is opening, connecting your planet to the sun.

Update to my previous post The Clouds of Saturn:

Our first intriguing glimse of Saturn’s North pole was from Voyager in 1980.  Last year, images from Cassini was the first time we got to view the entire North pole at one time.  Surprisingly there was 15,000 mile diameter hexagon made of clouds.

Scientist are again baffled because recent images show an aurora.  From Mysterious glowing aurora over Saturn confounds scientists.

A stunning light display over Saturn has stumped scientists who say it behaves unlike any other planetary aurora known in our solar system.

The blueish-green glow was found over the ringed planet’s north polar region just like Earth’s northern lights.

It was discovered by the infrared instruments on NASA’s Cassini spacecraft.

‘We’ve never seen an aurora like this elsewhere,’ said Tom Stallard, a scientist working with Cassini data at the University of Leicester.

‘This aurora covers an enormous area across the pole. Our current ideas on what forms Saturn’s aurora predict that this region should be empty, so finding such a bright aurora here is a fantastic surprise.’

Auroras are caused by charged particles streaming along the magnetic field lines of a planet into its atmosphere.

Particles from the sun cause Earth’s auroras. Many, but not all, of the auroras at Jupiter and Saturn are caused by particles trapped within the magnetic environments of those planets.

Jupiter’s main auroral ring is caused by interactions in Jupiter’s magnetic environment and remains constant in size. Saturn’s main aurora is caused by the solar wind, and changes size dramatically as the wind varies. However, the newly observed aurora at Saturn doesn’t fit into either category.

The new infrared aurora appears in a region hidden from NASA’s Hubble Space Telescope. Cassini observed it when the spacecraft flew near Saturn’s polar region.

In infrared light, the aurora sometimes fills the region from around 82 degrees north all the way over the pole. This new aurora is also constantly changing, even disappearing within a 45 minute-period.

‘There is something special and unforeseen about this planet’s magnetosphere and the way it interacts with the solar wind and the planet’s atmosphere,’ Cassini scientist Nick Achilleos from the University College London said.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

I worked at a psychic fair just over a month ago and met Sue. Sue was a Reiki practitioner and we spent some time talking about spiritual topics. I suspect that she was very good at Reiki because whenever she moved her hands I could feel waves of energy that trailed off them; like spreading waves from a passing barge hitting the shore. I could even feel the effect from 40 feet away but it took a second after she moved until I felt the wave.

Sue also was selling magnetic magnetic bracelets from a leading manufacturer. I didn’t think at the time that wearing magnets would affect a person’s health, but I decided to be open minded and give it a try.

Nikken bracelet

I haven’t studied the medical literature on wearing magnets. I suspect it says the same thing that the scientific literature says about psychic phenomena. When looking for psychic effects, if you believe in psychics, your study has a positive result. If you do not believe, your study is inconclusive or negative.

On a side note, I propose that science needs to borrow a page from anthropologists and study psychics in situ instead of in the lab.

I don’t normally get headaches but over the last five and a half weeks I have headache four times. I suspect that my eye glass prescription has changed a bit. Each time after putting the bracelet on, my headache was gone within five minutes. Scientifically conclusive, no, but interesting.

One thing I did not suspect was that wearing a bracelet would affect my dreams. I know there is no way to quantify this, and the general public would not be able to perceive the effect, but when I wear the bracelet to bed I had a much higher percentage of paranormal dreams compared to normal dreams. And my percentage of dreams recalled in the morning is much higher. In fact when I wear the bracelet to bed, I will remember the last three or four dreams I had before I woke up, instead of just one.

Here are some other blogs of mine that may relate to magnetic phenomena:

Gaia’s Magnetic Field
Deciphering the Crop Circle Code
The Cloud’s of Satun
The Magneurol 6S Advantage (Hint on this one: read the ingredients.)

Your homework is to investigate magnetic fields and see what you can find.

The surface of the Earth is made of giant tectonic plates that move. As some plates move farther apart, sea floor spreading is observed. At mid-ocean ridges, magma rises from the Earth and solidifies to fill the gap. The Earth’s magnetic field leaves it’s imprint on this material and allows us to examine the direction and magnitude of the magnetic field in the past. Every few hundred thousand years the field changes directions (a compass will point to the South pole instead of the North pole).

Since the 19th century the magnitude of the Earth’s magnetic field has weakened by about 10%. Here is some basic information from NASA on Earth’s Inconstant Magnetic Field. Much research is going on to attempt to understand the Origin of the Earth’s Magnetic Field.

I think the questions on everybody’s mind is what is going to happen in the future and how will it affect us? Some very doomsday scenarios are predicted. I don’t think the end of the world or end of humanity is likely but this is another phenomenon to which we should pay attention.

Something to keep an eye on from the NASA Cassini website in March 2007.

Cassini Images Bizarre Hexagon on Saturn
March 27, 2007
(Source: Jet Propulsion Laboratory) Pasadena, Calif. — An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with NASA’s Cassini mission.

NASA’s Voyager 1 and 2 spacecraft imaged the feature over two decades ago. The fact that it has appeared in Cassini images indicates that it is a long-lived feature. A second hexagon, significantly darker than the brighter historical feature, is also visible in the Cassini pictures. The spacecraft’s visual and infrared mapping spectrometer is the first instrument to capture the entire hexagon feature in one image.

“This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides,” said Kevin Baines, atmospheric expert and member of Cassini’s visual and infrared mapping spectrometer team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We’ve never seen anything like this on any other planet. Indeed, Saturn’s thick atmosphere where circularly-shaped waves and convective cells dominate is perhaps the last place you’d expect to see such a six-sided geometric figure, yet there it is.”

The hexagon is similar to Earth’s polar vortex, which has winds blowing in a circular pattern around the polar region. On Saturn, the vortex has a hexagonal rather than circular shape. The hexagon is nearly 25,000 kilometers (15,000 miles) across. Nearly four Earths could fit inside it.

The new images taken in thermal-infrared light show the hexagon extends much deeper down into the atmosphere than previously expected, some 100 kilometers (60 miles) below the cloud tops. A system of clouds lies within the hexagon. The clouds appear to be whipping around the hexagon like cars on a racetrack.

“It’s amazing to see such striking differences on opposite ends of Saturn’s poles,” said Bob Brown, team leader of the Cassini visual and infrared mapping spectrometer, University of Arizona, Tucson. “At the south pole we have what appears to be a hurricane with a giant eye, and at the north pole of Saturn we have this geometric feature, which is completely different.”

The Saturn north pole hexagon has not been visible to Cassini’s visual cameras, because it’s winter in that area, so the hexagon is under the cover of the long polar night, which lasts about 15 years. The infrared mapping spectrometer can image Saturn in both daytime and nighttime conditions and see deep inside. It imaged the feature with thermal wavelengths near 5 microns (seven times the wavelength visible to the human eye) during a 12-day period beginning on Oct. 30, 2006. As winter wanes over the next two years, the feature may become visible to the visual cameras.

Based on the new images and more information on the depth of the feature, scientists think it is not linked to Saturn’s radio emissions or to auroral activity, as once contemplated, even though Saturn’s northern aurora lies nearly overhead.

The hexagon appears to have remained fixed with Saturn’s rotation rate and axis since first glimpsed by Voyager 26 years ago. The actual rotation rate of Saturn is still uncertain.

“Once we understand its dynamical nature, this long-lived, deep-seated polar hexagon may give us a clue to the true rotation rate of the deep atmosphere and perhaps the interior,” added Baines.

The hexagon images and movie, including the north polar auroras are available at: http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov and http://wwwvims.lpl.arizona.edu .

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA’s Science Mission Directorate, Washington. The Cassini orbiter was designed, developed and assembled at JPL. The Visual and Infrared Mapping Spectrometer team is based at the University of Arizona.

NEWS RELEASE: 2007-034

 
 
 

 

And from EJP, “Just a heads up to yo all. I strongly suggest keeping an eye on this.   Enough said.  And yes it is important. “

Do I take the magnetic pill (formerly known as Magneurol 6-S) supplements?

Yes.

I take Magneurol and I have taken it continuously for about a year now.

Does it Help?

Yes.

When I first started taking it just less than 2 years ago there were two effects that I noticed immediately. I couldn’t talk on a cell phone for more than 2 or 3 minutes without getting nauseous. I was tuning into the energy field of the phone transmission, feeling it in my body, and my body didn’t know how to interpret it, so it felt like nausea. Fortunately that effect is long since gone.

Also my vision became sharper. Especially when looking at living things in direct sunlight. It was like shifting from watching the World Series in regular TV vs. in High Def. That effect is still around, but of course, it feels like the norm now, instead of something special.

How much does it help?

Hard to say. I guess you can judge my overall results based on what I have written. I would call them amazing.

I took it for 4 months. Then I stopped for 4 months. Now I have been taking it about a year. I looked back through my journals and counted the number of what I call “peak” experiences for a year surrounding the start/stop/start cycle. I couldn’t find a statistical difference in the number of experiences.

But I also meditate 2 times per day. Have been in the Higher Balance Star Reach Academy for 2 and half years. Changed coaches to prevent becoming “stale”. I have all the modules. Attended Higher Balance retreats in Portland and Hawaii. And I diligently practice the techniques. I also eat and live organically. .. Have removed chemicals from my environment as much as possible… Take a super high quality multi-vitamin… And get 8 hours of sleep per day.

It is worth the cost?

Yes.

But it depends. I would probably put it on the list as the fifth or sixth thing you should do, if you have the resources. If you are already doing the other five more important things and can afford to, then stack one more thing in your favor and do this too!
