It's grantology, to borrow a term. From the article:
"But superlensing does come at a cost... In other words, to image the
near-field it is necessary to remain in the near-field, otherwise those
components of light that contain the sub-wavelength spatial details
decay to the point that they cannot be recovered."

Well, I, in my own humble way, have taken occasion to scoff at
announcements of brave new worlds, but here I'll affect to be usure
just what you and Mati are scoffing at. Is it:
(1) that the technique is impractical, or
(2) that some minor advance in the technique is over-blown
In my experience, many scoffabilities seem to take form (2),
particularly where the science writer -- no doubt no unduly discouraged
by the researchers -- doesn't report the history of the subject, and
leaves the impression that the whole hog is due to the authors of the
latest increment.
The idea of using near field radiation for imaging is known:
http://physics.nist.gov/Divisions/Div844/facilities/nsom/nsom.html
But maybe this "negative refractive index" lens is a new variation.
The results seem to be real but unspectacular.

Yes, pure grantology. I'm afraid that Sam is too easily taken in by
fluff.

Oh, that's not fair to Sam- he's providing a reasonably useful service.
It's Physics World that originally hyped the "science", anyway.

Yes, no argument about this. He just should get a tad more jaded and
cynical:-)

Not the first time, and probably not the last.
