BIOTECH/GM: Biased books against and counterstrikes

Nature has a review of "Redesigning Life? The Worldwide Challenge
to Genetic Engineering", B. Tokar (ed.). Zed Books (2001).

The general tone of the review seems to suggest that the book is
a complete hack job trying to "sell" the positions of the authors.
Kind of along the lines of the "radical-sell" that Greg suggested
Rifkin's books are at Extro 5.

Partial quotes (trying to stay within the copyright laws...):

> The approach of Tokar and his colleagues is illustrated by three items that

Then a reference to potatoes with a lectin gene causing a furore in '98
citing Arpád Pusztai's 1999 Lancet paper that did *not* back up his claims
that they caused adverse effects on growth or the immune system (refs below).

I've read the abstract from that paper and cited it in my previous
review of the whole GM area. It was good science funded by the
AgBio industry to determine whether allergens transfer across species
and the answer is yes so they are really careful to minimize the
allergenicity of genes that go into food crops.

And then of course my new hero is Italian television producer of the science
prime-time show "Superquark" who is getting sued by homeopathists for his
'dissing of their profession.

Angela says:
  "Science is not like philosophy, where viewers can listen to both sides
   and decide for themselves, science cannot be decided on by the vote
   of viewers."
