Electrons flowing through power lines and computers inevitably encounter resistance; when they do, they lose some of their energy, which dissipates as heat. That's why laptops get hot after being used for too long and why ...

One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks ...
Superconducting materials show zero electrical resistance at low temperatures, which allows them to conduct "supercurrents" without dissipation. Recently, a group of scientists led by Dr. Kazumasa Iida from Nagoya University, ...
