Human magnetic sixth sense breaks into mainstream science

After decades of research proved that critters across the animal kingdom on Earth can sense our planet’s magnetic field, a well-known geophysicist at the California Institute of Technology (Caltech), Joe Kirschvink, has presented the first repeatable and verifiable evidence that humans have an ability to detect and respond to Earth’s magnetic field too.

Over the past decades, Prof. Kirschvink has originated several ideas aimed at increasing our understanding of how biological evolution has influenced, and has been influenced by, major events on the surface of the Earth. He won the Richard P. Feynman Prize for teaching excellence at Caltech, and the William Gilbert Award from the American Geophysical Union.

As opposed to previous results in this field, Kirschvink’s results are the first that can be repeated and verified. He has so far presented the results of tests performed on 24 human participants, and his paper is in progress. Kirschvink is sure humans have functioning magnetoreceptors and has received US$900,000 in funding to continue his research. There are currently three teams performing the tests, one is in the US, and the other two in Japan and New Zealand. A mobile lab is expected to be built soon too.

Kirschvink presented the results of his experiments at the 2016 meeting of the Royal Institute of Navigation in the UK. Details were provided to the public on June 23, 2016, in a Science Magazine article written by Eric Hand.

Kirschvink’s team is testing humans for a subconscious magnetic sense by putting them in a Faraday Cage and applying magnetic fields. “Faraday Cage is the key,” Kirschvink says. Its role is to screen out all electromagnetic noise.

The experiments began at the end of 2014.

Kirschvink was human subject No. 1. No. 19 is Keisuke Matsuda, a neuro-engineering graduate student from the University of Tokyo. Matsuda is replicating the experiment in Tokyo with a similar setup and same results.

“It’s absolutely reproducible, even in Tokyo,” Kirschvink says. “The doors are opening.”

Kirschvink favors a theory which proposes that miniature compass needles sit within receptor cells, either near the trigeminal nerve behind animals’ noses or in the inner ear. The needles, presumed to be made up of a strongly magnetic iron mineral called magnetite, would somehow open or close neural pathways.

“It’s part of our evolutionary history,” says Kirschvink. “Magnetoreception may be the primal sense.”

New Sunspots

Posted on by

MONSTER SUNSPOT: So you thought Halloween was over? Think again. There is a monster spot on the sun. AR2443 has more than quadrupled in size since it first appeared on Oct. 29th, and it now stretches more than 175,000 km from end to end. Philippe Tosi took this picture of the active region on Nov. 1st from his backyard observatory in Nîmes, France:

The sunspot has more than a dozen dark cores, many of which are as large as terrestrial continents–and a couple as large as Earth itself. These dimensions make it an easy target for backyard solar telecopes.

Of greater interest is the sunspot’s potential for explosive activity. The spotty complex has a ‘beta-gamma’ magnetic field that harbors energy for strong M-class solar flares. Any such explosions will be geoeffective as the sunspot turns squarely toward Earth in the days ahead.

SHOCK CLAIM: Large Hadron Collider magnetic field could pull asteroids towards Earth

The CERN Large Hadron Collider (LHC) could be responsible for drawing an asteroid that could destroy the planet towards earth, according to a wild conspiracy theory.

The LHC could generate a magnetic field that could somehow pull an iron-laden space rock off course towards Earth with catastrophic consequences, according to the crack pot theory which is doing the rounds online.

Another theory dreamed up by conspiracists is the LHC could even open up a portal from another dimension through which an unexpected comet or asteroid could suddenly appear before hitting Earth out of the blue.

Some have even bizarrely claimed the LHC could summon the Anti-Christ to earth to cause an apocalypse.

Scientists have readily dismissed these suggestions as ridiculous, but the LHC has long caused fear among certain quarters following claims it could potentially create a black hole which swallows up the planet.

The collider is within miles of tunnels, 75 metres under the French-Swiss border near Geneva, Switzerland, where scientists are smashing atoms to try to discover a parallel universe.

It is accepted by scientists that the LHC could cause a small black hole, but there has been no suggestion it could actually devour the earth or affect the movement of asteroids in space.

Various YouTube channels predict the Large Hadron Collider is about to ‘unleash hellfire destruction’ on the world, possibly while magnetically summoning a whacking great asteroid to destroy America’s east coast

Yahoo.com

This has not deterred Nostradamus style predictors.

One blogger suggested the LHC was a much more sinister machine, stating: “The CERN logo is 666 – the sign of the beast – in a circle.

“The CERN collider looks like the all-seeing eye or stargaze we see so much of.”

In a video, YouTube channel Paranormal Crucibale said: “We hear a lot of talk about CERN – portals and asteroids lately. CERN is creating a portal in space in anticipation for this event they are creating rumours of an asteroid strike when really they are not sure of the implications when cern removes the veil bet above and bel what might come out of that portal.”

There has been so much speculation over CERN drawing an asteroid towards Earth, Yahoo.com cited it as one of its top 11 craziest conspiracy theories.

The article said: “It seems that Christian conspiracy theorists haven’t forgiven the machine for finding the ‘God particle’ and now predict it’s going to bring about Doomsday.

“Various YouTube channels predict the Large Hadron Collider is about to ‘unleash hellfire destruction’ on the world, possibly while magnetically summoning a whacking great asteroid to destroy America’s east coast.”

Geomagnetic Storms Coming

Posted on by

FULL HALO CME, STORM WARNING: A coronal mass ejection (CME) is heading directly for Earth. It left the sun during the early hours of June 21st, and is expected to sweep up one or two lesser CMEs already en route, before it reaches Earth sometime on June 22nd. Click to view a movie of the “full-halo” CME, then scroll down for more discussion:

NOAA forecasters estimate a 90% chance of polar geomagnetic storms when the CME arrives. This doesn’t mean that a major space weather event is in the offing. The storm could be mild. It all depends on how the magnetic field of the CME connects to the magnetic field of Earth at the time of impact. According to NOAA, there’s only a 10% chance of nothing happening, so stay tuned.

Solar X-Flare 5/05

Posted on by

X-FLARE: The sun is no longer quiet. Emerging sunspot AR2339 unleashed an intense X2-class solar flare on May 5th at 22:11 UT. NASA’s Solar Dynamics Observatory captured the extreme ultraviolet flash:

A pulse of UV radiation and X-rays from the flare caused a strong radio blackout over the Pacific side of Earth. This map shows the extent of the blackout, which affected frequencies below 20 MHz. Mariners, aviators, and ham radio operators are the type of people who might have noticed the disturbance.

The explosion also hurled a CME into space: movie. Traveling faster than 1100 km/s (2.5 million mph), the expanding cloud does not appear to be heading for Earth.

In addition to causing a radio blackout, the flare also caused a radio burst. Immediately after the flare, a roar of static bellowed from the loudspeakers of shortwave receivers on Pacific isles and western parts of North America. Amateur radio astronomer Thomas Ashcraft of New Mexico recorded the outburst:

“The sound file is in stereo with one channel at 22 MHz and the other at 23 MHz,” says Ashcraft. “It is very intricate if listened to with headphones.”

What caused this burst of “solar static”? The same magnetic explosion that caused the flare also produced beams of electrons. As the electrons sliced through the sun’s atmosphere, they generated a ripple of radio-loud plasma waves. Astronomers classify solar radio bursts into five types; this one was a mixture of Type III and Type V.

SOlar FLares

Posted on by

OLAR FLARE AND RADIO BLACKOUT: Sunspot AR2257 erupted on Jan. 13th, producing an M5-class solar flare at 04:24 UT. A pulse of extreme UV radiation from the flare ionized Earth’s upper atmosphere over Australia and the Indian Ocean. Mariners and ham radio operators may have noticed a brief communications blackout at frequencies below about 10 MHz. This map from NOAA shows the affected region:

We do not yet know if the flare also produced a coronal mass ejection (CME). If so, the plasma cloud will probably miss Earth because of the sunspot’s off-center location on the solar disk.

More flares could be in the offing. AR2257 has an unstable ‘beta-gamma-delta’ magnetic field that seems poised to explode again. NOAA forecasters estimate a 40% chance of M-class flares and a 10% chance of X-flares on Jan. 13th.

Large Coronal Hole

Posted on by

HOLE IN THE SUN’S ATMOSPHERE: A vast hole has opened in the atmosphere over the sun’s south pole, and it is spewing solar wind into space. The gaseous gap, a.k.a. a ‘coronal hole,’ is colored dark-purple in this extreme ultraviolet image from NASA’s Solar Dynamics Observatory:


Curved lines trace the sun’s magnetic field in this EUV image from SDO

Coronal holes are places where the sun’s magnetic field opens up and allows solar wind to escape. A stream of solar wind flowing from this particular hole is expected to reach Earth’s orbit on Jan. 4-5. The bulk of the stream will flow south of our planet. However, not all of it will miss. NOAA forecasters estimate a 40% chance of polar geomagnetic storms when the solar wind arrives in the next 48 hours.

Incoming CME 12/19

Posted on by

CHANCE OF MAGNETIC STORMS TODAY: A CME is heading in the general direction of Earth, and it could deliver a glancing blow to our planet’s magnetic field later today. Scroll past this SOHO coronagraph movie for storm probabilities:

NOAA forecasters estimate a 50% chance of polar geomagnetic storms. The cloud was hurled into space two days ago by an M9-class explosion in the magnetic canopy of sunspot AR2242. Although the bulk of the CME flew south of the sun-Earth line, a collision is still possible. Computer models suggest a glancing impact on Dec. 19th with magnetic reverberations lasting until the 20th. High-latitude sky watchers should be alert for auroras.

Huge Skull-like Sunspot

Posted on by

SUPER-SUNSPOT PREPARES TO DEPART: The biggest sunspot in nearly 25 years is about to leave the solar disk. This picture from Sergio Castillo of Corona CA shows AR2192 approaching the western limb on Oct. 27th:

“For its final trick, AR2192 is going to treat us by mimicking a Giant Skull,” says Castillo, one of many readers who has noted the resemblance between the sunspot and a skeletal face. “Say Happy Halloween as it gets ready to turn away from us. “

As AR2192 approaches the sun’s horizon, it is no longer facing Earth. However, the odds of an Earth-directed radiation storm are higher than ever. The reason is, the western limb of the sun is well-connected to Earth. Solar magnetic fields springing out of that region spiral back to our planet. If a sunspot passing through the area explodes, those spiralling magnetic fields can funnel energetic particles in our direction.

In only a few days, the behemoth sunspot will begin a 2-week transit of the far side of the sun, carried around by the sun’s 27-day rotation. However, that doesn’t mean we’ve seen the last of this magnificent active region. Big sunspots typically persist for two or three solar rotations before they decay. After it leaves, AR2192 will return in November.

Using Magnetic Fields for Power Transfer

Wireless Power Transfer Achieved Using Magnetic Field

Activist Post

The way electronic devices receive their power has changed tremendously over the past few decades, from wired to non-wired. Users today enjoy all kinds of wireless electronic gadgets including cell phones, mobile displays, tablet PCs, and even batteries.

The Internet has also shifted from wired to wireless. Now, researchers and engineers are trying to remove the last remaining wires altogether by developing wireless power transfer technology.

Chun T. Rim, a professor of Nuclear & Quantum Engineering at KAIST, and his team showcased, on April 16, 2014 at the KAIST campus, Daejeon, Republic of Korea, a great improvement in the distance that electric power can travel wirelessly. They developed the “Dipole Coil Resonant System (DCRS)” for an extended range of inductive power transfer, up to 5 meters between transmitter and receiver coils.

Since MIT’s (Massachusetts Institute of Technology) introduction of the Coupled Magnetic Resonance System (CMRS) in 2007, which used a magnetic field to transfer energy for a distance of 2.1 meters, the development of long-distance wireless power transfer has attracted much attention for further research.

However, in terms of extending the distance of wireless power, CMRS, for example, has revealed technical limitations to commercialization that are yet to be solved: a rather complicated coil structure (composed of four coils for input, transmission, reception, and load); bulky-size resonant coils; high frequency (in a range of 10 MHz) required to resonate the transmitter and receiver coils, which results in low transfer efficiency; and a high Q factor of 2,000 that makes the resonant coils very sensitive to surroundings such as temperature, humidity, and human proximityProfessor Rim proposed a meaningful solution to these problems through DCRS, an optimally designed coil structure that has two magnetic dipole coils, a primary one to induce a magnetic field and a secondary to receive electric power. Unlike the large and thick loop-shaped air coils built in CMRS, the KAIST research team used compact ferrite core rods with windings at their centers. The high frequency AC current of the primary winding generates a magnetic field, and then the linkage magnetic flux induces the voltage at the secondary winding.

Scalable and slim with a size of 3 m in length, 10 cm in width, and 20 cm in height, DCRS is significantly smaller than CMRS. The system has a low Q factor of 100, showing 20 times stronger against the environment changes, and works well at a low frequency of 100 kHz. The team conducted several experiments and achieved promising results: for instance, under the operation of 20 kHz, the maximum output power was 1,403 W at a 3-meter distance, 471 W at 4-meter, and 209 W at 5-meter. For 100 W of electric power transfer, the overall system power efficiency was 36.9% at 3 meters, 18.7% at 4 meters, and 9.2% at 5 meters.

“With DCRS,” Professor Rim said, “a large LED TV as well as three 40 W-fans can be powered from a 5-meter distance.”

“Our technology proved the possibility of a new remote power delivery mechanism that has never been tried at such a long distance. Although the long-range wireless power transfer is still in an early stage of commercialization and quite costly to implement, we believe that this is the right direction for electric power to be supplied in the future. Just like we see Wi-Fi zones everywhere today, we will eventually have many Wi-Power zones at such places as restaurants and streets that provide electric power wirelessly to electronic devices. We will use all the devices anywhere without tangled wires attached and anytime without worrying about charging their batteries.”

Professor Rim’s team completed a research project with the Korea Hydro & Nuclear Power Co., Ltd in March this year to remotely supply electric power to essential instrumentation and control equipment at a nuclear power plant in order to properly respond to an emergency like the one happened at the Fukushima Daiichi nuclear plant. They succeeded to transfer 10 W of electricity to the plant that was located 7 meters away from the power base.
