Mommmmm!!!! Looooook!!



"NUCLEAR MAGNETIC RESONANCE IMAGING WITH 90-nm RESOLUTION has been
achieved by John Mamin and his colleagues at the IBM Almaden lab in
San Jose, California. The approach used, magnetic resonance force
microscopy (MRFM), maps the location of matter at small scales by
observing the resonant vibration of a spindly sliver of silicon
(bearing the sample in question) when it is both exposed to
radio-frequency waves and scanned over a tiny magnetic tip (see
figure at http://www.aip.org/png/2007/278.htm ). Previously this
same group of physicists had used a similar setup to detect the
magnetic resonance of a single unpaired electron in a sample
(http://www.aip.org/png/2007/278.htm) But now they are detecting
the magnetic resonance of nuclei in the sample, a much more
difficult thing since nuclear magnetism is much weaker than electron
magnetism (in the case of hydrogen some 660 times weaker). "

These guys are still doing Science!!! Isn't that supposed to be iiegal now or something?
