Just a comment: Lands snails sensing magnetic fields are described in an 
overview by Barnothy (Biological Effects of Magnetic Fields, published 
in 1964).

I heard of these and wonder where the antenna is - so there is

not a misinterpretation between magnetic field effects and

electric current conduction (small cross sections with relatively

high current could occur like in ion channels - the total cross

section may not be representative).

Wait a minute. W/cm2 That is power/area. For a 50 Hz field the wave 
length is 6000 kms. So in order to obtain meaningful energy (cross

product ExB) the frequency must be very high. I would like to

know more about that.

I think some serious objections have been raised regarding either the 
scoring technique or the statistics used in this assay (I can

check it - there was something extreme I think (a judgement

involved in the scoring??).

Yes - Kirschvink et al. have written excellent reviews on the topic.

What does "stopper" mean in mechanistic terms?



I am only asking for an experiment that deals with cancer

induction/promotion mechanisms. Many experiments were performed

with lymphocytes that have been proven to actively take up

magnetite - from media (RPMI, Gibco for instance) that have

been proven to contain ferromagnetic particles. A shown effect

in a particular system does not prove that it has to do with

cancer induction/promotion. To my knowledge, no such suggested

mechanism has been possible to reproduce by an independent group.



The only mechanism I could imagine would be over the

retina/corpus pineale ->melatonin->estrogen->breast cancer

but if that is a pathway - it will be extremely difficult to

prove since light works over the pineal gland (I think artificial

light may be a serious candidate for part of the breast cancer

in western countries - but the topic is extremely complex with

other involved factors - mainly relating to fats and estrogen). 
Experiments with animals like rats won't work because they are night

animals.



Sorry about these first, somewhat vague comments (taken out of my 
memory), I am at home with the wrong kinds of info. around me and

it is about time to hit the sack. Have to come back to this one.

PS. Some embryonic experiments (published in a "respectable journal") 
with - to my taste unclear experimental setup and questionable 
statistics - were performed by a person I have met a lot (I had to). 
This person also does palmistry, reads astrology and eats various 
strange pills for no clear reason. I know - this is unscientific "guilt 
by association" - but I just cannot get it out of my mind. Can't give 
you more details on this one. I encounter so many strange people - one 
man a couple of years ago wanted 30000 USD to put crystals out in a 
field ("research") near power lines (they crossed some Curry lines or 
whatever they were called - only he knew where they were) because they 
were supposed to make the cows there infertile.
