(PhysOrg.com) -- Every chemistry student knows that if you stir a mixture of chemicals you speed up the reactions between them, but less well-known is that chemical reactions can themselves stir up the mixture. This was demonstrated ...
A powerful engine roils deep beneath our feet, converting energy in the Earth's core into magnetic fields that shield us from the solar wind. Similar engines drive the magnetic activity of the sun, other stars and even other ...
