In the blink of an eye in geological time, Canada has lost one north pole but gained another, a new and different claim to be ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

Physicists have found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way which has ...

The new magnetic sensor is inexpensive to make, works on minimal power and is 20 times more sensitive than many traditional sensors. A team of Brown University physicists has developed a new type of ...
