Three scientists win Nobel physics prize

Three scientists won the Nobel physics prize on Tuesday for contributions made many years ago to understanding what happens to materials at extremely low temperatures. Some lose all resistance to electric current - superconductivity - and others lose resistance to physical movement - superfluidity.

Alexei Abrikosov and Vitaly Ginzburg made their discoveries about electrical superconductivity in Russia during the 1950s and 1960s. Professor Abrikosov, 75, moved to the US in 1991 and now works at the Argonne National Laboratory in Illinois. Prof Ginzburg, 87, is still carrying out research at the P. N. Lebedev Physical Institute in Moscow.
