However, the heart's intrinsic electrical system can keep the organ beating for a short time after a person becomes brain-dead â in fact, the heart can even beat outside the body, Greene-Chandos said.

An unusual, temperature-dependent effect displayed in the thermal, electrical, and magnetic properties of nonmagnetic metals containing very small quantities of magnetic impurities. A striking example is the anomalous, logarithmic increase in the electrical resistivity with decreasing temperature. Other properties, such as heat capacity, magnetic susceptibility, and thermoelectric power, also display anomalous behavior because of the Kondo effect.
