Earth’s magnetic north pole has officially moved

Earth’s magnetic North Pole has drifted so fast that authorities have had to officially redefine the location of the magnetic North Pole. The extreme wandering of the North Pole caused increasing concerns over navigation, especially in high latitudes.

Earth’s magnetic field is known to have wandered and flipped in the geologic past. Earth’s magnetic field is a result of spinning molten iron and nickel 1,800 miles below the surface. As the constant flow of molten metals in the outer core changes over time, it alters the external magnetic field.

What we’ve seen in the past hundred years is that the location of the magnetic North Pole has moved northward. That migration of the magnetic North Pole was switched into overdrive in the past few years, causing the pole to rapidly move. The increased speed with which the magnetic North Pole has moved prompted authorities to officially update its location. The official location of the magnetic poles is specified by the World Magnetic Model, which acts as the basis for navigation, communication, GPS, etc. around the globe.

NASA’s ‘impossible ‘ space engine tested-here are the results


The first independent tests of the EmDrive suggest there’s a mundane explanation for the wildly controversial device.

Spaceflight is hard. Blasting heavy cargo, spacecraft, and maybe people to respectable speeds over interplanetary distances (not to mention the luxury of stopping at destinations) requires an amount of propellant too massive for current rockets to haul into the void.

That is, unless you have an engine that can generate thrust without fuel.

Scientists design a novel magnetic cloaking device

magnets 5859976

Scientists have just created the antimagnet.

Scientists from the Universitat Autònoma de Barcelona designed a magnetic cloak that’ll both shield an object from an outside magnetic field and prevent an internal one from leaking out. It’s an antimagnet and it’ll have various military and medical applications.

The antimagnet uses a superconducting material that blocks the internal magnetic field of an object and several dampening layers to block the effect of the superconductor on the external magnetic field. Sounds complicated, and it is, but it could save your life some day…

Migrating Robins Can Actually See Magnetic Fields

It has been known for decades that some birds are able to sense the Earth’s magnetic field and set their direction as if following a compass heading, which is an extremely useful ability for birds migrating long distances. The ability is believed to be linked to the availability of light and it is thought that specialized molecules in the birds’ retinas allow them to literally see the magnetic fields, which appear as patterns of light and shade superimposed over the regular image from light. Now a new study shows that the internal compass also depends on the birds having clear vision in their right eyes.

Photo of the Only Atomic Bomb Ever Detonated in Space


Exploding nuke in space.

Since we’re coming up on the Fourth of July, and towns everywhere are preparing their better-than-ever fireworks spectaculars, we would like to offer this humbling bit of history. Back in the summer of 1962, the U.S. blew up a hydrogen bomb in outer space, some 250 miles above the Pacific Ocean. It was a weapons test, but one that created a man-made light show that has never been equaled — and hopefully never will. Here it is: (video)

Archaeological ‘Time Machine’ Revealed

Evolutionary Time Machine
Researchers at Queen’s University have helped produce a new archaeological tool which could answer key questions in human evolution. The new calibration curve, which extends back 50,000 years is a major landmark in radiocarbon dating– the method used by archaeologists and geoscientists to establish the age of carbon-based materials.
It could help research issues including the effect of climate change on human adaption and migrations.

The project was led by Queen’s University Belfast through a National Environment Research Centre (NERC) funded research grant to Dr Paula Reimer and Professor Gerry McCormac from the Centre for Climate, the Environment and Chronology (14CHRONO) at Queen’s and statisticians at the University of Sheffield.

Zero Emissions Car Powered By Magnetic Fields


The Transporter TW

With concept designers crafting their fantasies into a consumable form, we believe that the era of tomorrow would be completely different than present days. Harsha Vardhan, a car designer, thinks that apart from the cities, cars too would be completely different and powered by technologies no car manufacturer has tried till date. He fantasizes a car powered by magnetic field generated by on-board electricity powered systems. (Pics)

 Northern Lights

UCLA space scientists and colleagues have identified the mechanism that triggers substorms in space; wreaks havoc on satellites, power grids and communications systems; and leads to the explosive release of energy that causes the spectacular brightening of the aurora borealis, also known as the northern lights.
