That's what I was saying... they find it more of a bore/chore and

I've also seen people [mostly grad students] use the radioactive
garbage for biohazadous (and visa versa)... I've seen one secretary
clean out an entire filing cabinet and toss the papers in the
radioactive garbage because (it was a large enough container to fit
everything at once). I've seen M.D.s who are constantly tossing
papers into both ones (they have no concept of the cost involved in
processing this waste).
I've also seen students who are afraid they may have already had
their monthly allotment of exposure (how they figure this I have no
idea) so they don't wear their badges for a few weeks (they keep
them in one of those lead transport containers).
I've seen people who handel radioactive material and then answer
the phone without taking their gloves off (and I hand to *insist*
to the local safety officer that he takes a swipe of the phone!...
a phone I refuse to use unless I wore gloves actually since this
was a constant habit of theirs)
I've seen people toss radioactive material down the wrong sink (ie.
a community sink which was not designated as a radioactive one).
And only on one occasion have I seen where they had to remove and
entire wall from misuse (BTW, the tech's nickname was Wild Bill...
that was years ago, never knew what happened to him later in his
And once I saw a door to a room completely sealed shut with all
sorts of warnings, etc. on it... never new what had happened but
the date on the door went back a few years? Whatever it was...
they never got around to cleaning it up?
etc. etc. etc.
I know the people who run the radiation safety office is very
serious about what they do... but they are just not as serious as
the P.I.s who only care about end results of experiments and the
students/techs who don't know better or who just plain don't care.
And in all honesty, how this all effects safety... I don't really
know. Mostly I just do what I am told.

This is all fine and good on a state level... but as far as I was
lead to believe, federal institutions do self-policing. They are
not subject to state inspections.

True. Very true. I've also seen foreign students who barely spoke
english who were brought into this country to work for a particular
guy... they had little to no idea how to handel radioactive
materials and was allowed to work with some very hot stuff (don't
ask me which one, I know very little of this subject)... anyway, in
the end nobody on the entire floor was willing to share the lab
with them - everybody moved their radioactive work to different
labs and left the guys alone because they were so sloppy. [this
was federal labs BTW]

All I can tell you is we see how much we started with... and when
we do the inventory at the end of the month; we make sure it
exactly adds up (between sink and garbage). I was told half-life
calculations are tricky and don't even bother... just make sure the
numbers add up. And that's about as far as I have been trained in
In truth, I have not used a lot of radioactive materials in my
career... only once in a while. I don't do gels on a regular

Good points. But I think you hit it right on the head... it has to
have *real* teeth. And as much as I like my own idea... I tend to
doubt a system such I have described would be allowed to have
*real* teeth? Thus my hypothesis.

"If the recent results finding both genes and viruses associated
with various cancers are good work,..."
Again, you hit the nail right on the head.
No this has not been good work... it has been slow in coming.
And if you read the book "A Conspiracy of Cells" by Michael Gold,
you'll see why.
The major problem with cancer research has been cross-cell
contamination. This dates back to the very beginning of cell
culture but was not discovered until the early 1970's... when HeLa
cell contamination was first identified.
And with HeLa cell contamination came various monkey virus
contaminations into various tumor cell lines. [because HeLa cells
were used in early polio labs for titer testing - thus they 'picked
up' various monkey viruses and brought these viruses with them when
they contaminate a cell line]
There are famous stories of people who worked with one cell line
only to find it was something entirely different. For example, one
guy worked for 16 years on what he 'thought' was a prostate cancer
cell line... only to find it was HeLa (cervical cancer). I believe
it took him another 2-3 years before he would admit it in public?
Anyway, guidelines were established which would then minimize the
possibility of cross-cell contamination... but 20 years later...
not only do people still not abide by these guidelines - but with
modern testing techniques, it is very easy to do cross-cell
contamination testing (species specificity testing) - but very few
labs bother to do this (*very* few).
And as recently as last summer, I interviewed with a guy at Cook
County Hospital here in Chicago who claimed he had found evidence
of a virus in his prostate cancer cell line some years ago... but
was never able to identify it... considering his lab set-up - I had
no doubt he found evidence of a virus... it was more than likely a
monkey virus from a HeLa cell contamination!
And take Dr. Mokyr's lab as I previously described... where she had
a cell line which had changed but instead of species specificity
testing - she just decided to attribute this to genetic drift. If
this is indeed cross-cell contamination... how does this effect the
identification of the tumor markers she is working so hard on?
I can go on and on with what I have seen... it's no wonder this
work is slow in progress. And when some progress is made... often
it's not able to be duplicated or once you get it to human level of
testing, it doesn't work as well as initial testing indicated it
And as long as people decide this ignore this problem of cross-cell
contamination and do sloppy work... progress will remain slow in
Thus, sloppy work is a very big part of the problem in Cancer (and
I suspect AIDS) research.
On a more personal note:
You know, I just came back from seeing the movie Apollo 13 [great
movie by the way!]
Anyway, it reminded me of why I left that federal lab I was working
in. My uncle had just died of lung cancer and I had decided I had
had enough of working with poor quality graduate students in a low
caliber lab... I wanted to get back to cancer research and do
'something'. So when I ran into this particular M.D. in an
elevator and he offered me a chance to do just that - I grabbed it.
I had such high hopes and dreams... not that I would find a cure or
something like that - but just to be able to add something
significant to the pool of knowledge that may one day help to find
Anyway, after three weeks working there I discovered differently...
I had bought into a pipe dream.
Anyway, he talked me into just chugging alone and trying to get the
lab up and running... promising me everything else would just 'fall
into place' later. I knew this would not be true but I gave it my
Then one night me and my mother sat up and watched them do the
repairs of the Hubble Space Telescope... the team work, the
dedication, the paying attention to details - it was amazing. And
somewhere between 2-3 am in the morning it finally hit me - that's
what I was looking for. Oh no, not to go into space... just the
feeling of working with a group of people all with one goal. And
who puts that goal above everything else.
Anyway, the next day I went into work and looked around the labs...
at the pile of dirty mouse cages sitting in one corner, the
surgical instruments sitting points down [rusting] in a beaker of
water, the bench tops dirty with tiny pieces of animal's skins
which never got cleaned up and in what was suppose to be a
molecular lab; all the glassware sitting on shelves out in the
open, bottles of reagents with 1-2 years old dates on them and
little fuzzy things growing on the bottom, and a water bath so
dirty you couldn't even see the bottom for all the fuzz growing in
Later that same day I watched these two guys I worked with drop
what they were doing so that they could take their daily hour-long
lunch [which was exactly at the same time every day] and then I
watched them go home [one at 2:30pm and the other at 3:30... no,
they did not come in early]
Anyway, that's when I sat down and wrote my letter of
resignation... challenging him to either fire these guys and allow
me clean up the place; or let me leave - a few months later I left
with what I previously wrote as to what he said to me about
significant discoveries being random events.
And ladies and gentlemen, that's what is missing from cancer and
AIDS research... dedication, paying attention to 'details,' putting
the validity and credibility of the work above politics, greed and
egos and working as a team to find a cure.
Science of the 90's have lost all of these properties... these
exact same properties which got us to the moon and back.
You know... for all of the complaints directed towards NASA over
the years to help justify constantly cutting their budgets... at
least they have had more accomplishments than the NIH could claim -
who have had much less budget cuts over the years.
It's funny... but when the public gets mad at slow [or lost] mail
deliveries - the Post Office reorganizes. When NASA is under fire
for loosing a shuttle [and admittedly, it took an accident of such
magnitude to demand it] - but they re-organized.
So when are people going to have had enough of the lack or progress
towards AIDS and cancer research and demand the NIH reorganizes?
Like I've written before - a day may come when one too many a
person will have died [combined with one too many investigations
for misconduct] before something will be forced to be done?
I don't know.
