# 7: Spooky Entanglement
One of the strangest predictions of the theory of quantum mechanics is that particles can become “entangled” so that even after they are separated in space, when an action is performed on one particle, the other particle responds immediately.
In June 2009 scientists announced they had measured entanglement in a new kind of system – two separated pairs of vibrating particles. Previous experiments had entangled the internal properties of particles, such as spin states, but this was the first time scientists had entangled the particles’ pattern of motion, which is a system that resembles the larger, everyday world.

Earth’s north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet’s core, new research says.
The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field’s movements by tracking how Earth’s magnetic field has been changing at the surface and in space.
Now, newly analyzed data suggest that there’s a region of rapidly changing magnetism on the core’s surface, possibly being created by a mysterious “plume” of magnetism arising from deeper in the core.
And it’s this region that could be pulling the magnetic pole away from its long-time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France.
Finding North
Magnetic north, which is the place where compass needles actually point, is near but not exactly in the same place as the geographic North Pole. Right now, magnetic north is close to Canada’s Ellesmere Island.

MIT students build a high-altitude, photo-snapping balloon using off-the-shelf components
Scientists and students alike have previously launched low-budget balloons that rise to the upper reaches of Earth’s atmosphere, snapping unbelievable photos from near-space. But MIT’s Icarus team managed the same feat using only off-the-shelf items, and for a measly cost of $150. Here’s how they did it.
The MIT students list everything that they used to assemble the launch vehicle, including a prepaid Motorola i290 phone with GPS, a cell phone charger and disposable hand warmers to keep everything operable at the cold high altitudes. Basic materials such as newspaper, zip ties, duct tape and a Styrofoam beer cooler also came in handy.
“We bought a AA-battery cell phone charger to sustain the phone’s power over the duration of the flight, and we used Energizer lithium batteries (rated to operate at temperatures are low as -40F) to power both this charger as well as our camera,” the Icarus team wrote on their website.
