What is Luc Montagnier's research on electromagnetic signals from DNA about?

I think that ymar poses an excellent set of questions that should be discussed on these forums. It brings back memories (sic) of the memory of water controversy.

I'll quote from Andy Coghlan's excellent article published in New Scientist in 2011

Draw your own conclusions. (The emphases are mine).

... So what have
Montagnier and his team actually found? Full details of the
experiments are not yet available, but the basic set-up is as follows.

Two adjacent but physically separate test tubes were placed within a
copper coil and subjected to a very weak extremely low frequency
electromagnetic field of 7 hertz. The apparatus was isolated from
Earth's natural magnetic field to stop it interfering with the
experiment. One tube contained a fragment of DNA around 100 bases
long; the second tube contained pure water.

After 16 to 18 hours, both
samples were independently subjected to the polymerase chain reaction
(PCR), a method routinely used to amplify traces of DNA by using
enzymes to make many copies of the original material.

The gene
fragment was apparently recovered from both tubes, even though one
should have contained just water (see diagram).

DNA was only recovered
if the original solution of DNA - whose concentration has not been
revealed - had been subjected to several dilution cycles before being
placed in the magnetic field. In each cycle it was diluted 10-fold,
and "ghost" DNA was only recovered after between seven and 12
dilutions of the original. It was not found at the ultra-high
dilutions used in homeopathy.

Physicists in Montagnier's team suggest
that DNA emits low-frequency electromagnetic waves which imprint the
structure of the molecule onto the water.

This structure, they claim,
is preserved and amplified through quantum coherence effects, and
because it mimics the shape of the original DNA, the enzymes in the
PCR process mistake it for DNA itself, and somehow use it as a
template to make DNA matching that which "sent" the signal

I always knew there was something suspect about genetics! Stick to biochemistry, that's what I say :-)
