However, the electron spin resonance data would seem to confirm original suggestions about the bones.

Within the limits of accuracy of the experiment, positron spin-flipping seems to happen at the same frequency as electron spin-flipping.
"What I was doing was taking these bones and seeing whether in fact I could see electron spin resonance spectra getting progressively smaller and ending up with carbon, " said Dr Skinner.

This is because the degree of carbonisation of organic material as measured with electron spin resonance is dependent only upon the amount of carbon and not on the time material has been heated for.

Andrew Kent, a physicist at New York University, spends most days running electricity through a magnet smaller in diameter than a single cell, trying to determine the lowest current at which an electron's spin changes orientation.
Grandis makes a non-NAND flash solid state storage technology called spin-transfer torque RAM (STT-RAM) that stores information via the direction of magnetization in a spin-polarized electron current.

Bombard an ordinary hydrogen atom with microwaves of the right frequency and you will lift it out of its ground state by flipping the spin of its electron.
Electrons are subatomic spinning tops: Spin up and spin down are the electron's version of clockwise and counterclockwise.
In particular, every electron has its own magnetic field aligned with the axis of its spin.
These are superpositions of ones and zeros and are represented by, for example, the direction of spin (with respect to a magnetic field) of a particle such as an electron.
Because an electron is small enough for quantum effects to be routine, it is perfectly possible for such a spin to be pointing up and down at the same time.
