Physicists Improve Spin Information Storage 43
schliz writes "Researchers have made headway into developing spintronic RAM by successfully transferring spin information from an electron to a more robust atomic nucleus and accessing the information 2,000 times in 100 seconds before it decayed (abstract). The demonstration was conducted using phosphorus-doped silicon in a highly magnetized, low-temperature environment (8.59 Tesla, -269.5 degrees Celsius). Other researchers have achieved spin lifetimes of 30 hours in a weaker magnetic field (0.3 Tesla)."

Subatomic things tend to move around when they get warm. Cooling them keeps them where they're put, it's easier to find them that way.

A more general explanation could be that new stuff happens at very low energies and very high energies compared to what we're used to. Cold is just low energy.

It is NEVER appropriate to use Rankine.
