Superconductor levitates around circular supermagnet track

High-temperature superconductor (Yttrium barium copper oxide) floating in the magnetic field of Neodymium magnets. This phenomenon is called the Meißner-Ochsenfeld-Effect and was discovered in 1933. The superconductor has to be cooled with liquid nitrogen which has a temperature of 77 K or −196 °C. If it is placed in a strong magnetic field it remains in its position. It also works if you turn the track upside down

Bionic feet becoming reality

Natural disasters like the earthquake in Haiti and man-made tragedies like soldiers or civilians losing limbs to explosives drive the need for better prosthetic limbs. Improved treatments are on the horizon in the form of novel foot and ankle prosthesis which behave energetically more like the human body than existing technologies. These powered devices can […]
