1945 : as apogee AND nadir of Modern Science

Hitler may have successfully convinced his most rabid followers that the murder of every last Jew in Europe was a fitting consolation prize for his failure to deliver up western Russia as the new frontier for the Aryan super race in 1941.

But the rest of humanity regarding Auschwitz as a particularly (and peculiarly)  modern and scientific crime made it particularly hard for modern scientists in the rest of the world to present their continuing support of eugenics as the public face of postwar biology.

Still Auschwitz in the end proved a godsend to Oswald Avery's 1944 reductionist claims that Free Will didn't really exist but was simply manipulated by the chemical workings of a simple molecule called DNA.

A forgotten meme from "The Golden Age of Mysteries" held sway over wartime penicillin : to the detriment of the dying

The grey-haired teenagers of the 1870s to 1890s, the guys who actually ran World War Two, grew up on the stories of the Golden Age of Mysteries and Detectives, starting with Sherlock Holmes' Study in Scarlet in 1887.

And one thing you quickly learned in all those thousands of books in dozens of languages was that the formula that the spy had stolen from the safe - the formula upon which the fate of the Empire ( or perhaps even the world) hung - was never a formula in physics or biology or geology or astronomy.

It was always a formula in Chemistry : always a formula for the synthesis of some extremely powerful explosive or fuel or drug.

The re-invention of a military-only antiseptic into "bedside penicillin for all" creates a global beacon of hope for a world at war

the tiny stone the builders rejected
Despite the self-centred claims of physicists, the greatest benefits to humanity have generally been ardently pursued (invented), not accidentally stumbled upon (discovered).

DNA was discovered in 1860s by an Swiss doctor, but for most of us, it was really only discovered 125 years later in the late 1980s.

That was when it began to first be successfully used to solve unsolved criminal cases, when British researcher Alec Jeffries re-invented 'DNA' as a means to definitely identify biological evidence left at the scene of a crime.

"Race",before DNA, was BLOOD : literally. The hidden subtext behind penicillin's 15 year delay.

BLOOD was destiny, before DNA
The discovery of different blood types in the early 20th century allowed the science of eugenics to 'claim' a scientific basis for denying marriage between people of different colours, because it meant the mixing of their blood.

Crick's DNA Central Dogma is 80% JUNK, new 'Encode' project intimates

Crick's central Dogma is dead
Crick's simple-minded Central Dogma of DNA : that there is a single physical spot on your chromosome that encodes for bed wetting and for why some men prefer Arsenal instead of Manchester United, has been revealed to be 80% junk by the new ENCODE project.

Recombinant DNA and HGT's contribution to the penicillin saga

Where does one begin?

The beta-lactam molecular 'core' was originally created by bacteria and was only later was moved by HGT/ recombinant DNA into some fungi .

Those fungi then created the penicillin-variants of that very special fused beta-lactam ring .

But while this HGT operation was obviously fundamental to there being a penicillin saga to begin with, it had little direct impact on how the 1929-1944 penicillin saga actually unfolded.

But the four years of hard work and disappointments that Martin Henry Dawson endured between the Fall of 1926 and the Fall of 1930  working on HGT and recombinant DNA exchanges did make him the best qualified researcher in the world to put up with the temperamental penicillium between the Fall of 1940 and the Fall of 1944.

 His pioneering work with R to S type  (and S to S type) HGT exchanges between Strep pneumococcus bacteria made him eminently qualified to stand up to all the difficulties in growing penicillium to produce penicillin.

Dawson was the first in the world, together with Richard Sia, to successfully induce R to S pneumococcus HGT DNA exchanges in a test tube after most other researchers threw up their hands in despair and moved onto other research.

But he was no quitter and he pulled it off after years of failure.

Dawson then went on, with Agnes Warbasse, to do the same with S to S HGT DNA exchanges and this remains extremely difficult to do naturally, as Dawson did it.

He then went on to successfully grow colonies of M and L types of bacteria, all part of his effort over the roughly 15 years between 1926 and 1941 to establish that R,M,L were fully co-equal equivalents or alternatives to S types of bacteria - not defective or deficient versions of it.

This postmodernist notion naturally was seen as bizarre or worse in the strongly modernist atmosphere of medical research between the wars.

I see it as the bacterial equivalent of Dawson treating 4F civilians as the exact moral equivalent of 1A soldiers, not as defective 'useless mouth' variants,  despite the reign of Total War Utilitarianism ruling western medicine between 1940 and 1945.

Dawson's pioneering HGT DNA/ Q-sensing work taught him ethics and it taught him technical skills - both which he called upon to get penicillin successfully launched......

Oswald Avery : unknown and famous for the wrong things...


It is the tragedy of Halifax Nova Scotia born Oswald Avery that he is famous for a study he didn't really believe in (and opposed for years) and he is unknown for his lifework, which today saves millions of childrens' lives around the world each year.

Oswald Avery is today known as 'The Father of Molecular Biology' , which should tip us off right from the start.

Scientists are never more manipulative and intellectually dishonest than when they are fabricating the history of the "Father" (never the "Mother" or "parents") of their particular branch of science.

Avery is no exception. In this case, we know this to be so, because the person who created the myth of Avery (Joshua Lederberg) said so: he intended to 'do a Mendel on Avery'.

Gregor Medel did wonderful pioneering work , but his credentials for being considered the father of any science are widely regarded today as spurious - and he would be the first to say so loudly if he came back today.

As would Avery regarding his alleged founding role in molecular biology - to his credit, he never claimed much for his work in this field while he was alive - and he lived for 10 years after his 'big' discovery.

But in the saving-the-lives-of-millions-of-innocent-baby-children world, the world of conjugate vaccines, Avery is a GIANT - or should be.

He certainly is to the researchers in that field.

But he is merely 'the key individual' in an effort that spanned a century and included every continent,thousands of researchers and hundreds of millions of dollars.

It is a story far too vast and far too complicated for popular science reporting to credit to any one medical super hero and one shining experimental result: no Pasteur or Jonas Salk here.

Instead Avery is praised for one 'seminal-paper-that-was-ignored-at-the-time' --- which rather implies an intellectual oxymoron and suggests the difficulty in crediting him as the Father of anything .

That paper was published in February 1944 but had its formal beginnings with experiments that began on October 22nd 1940 on Manhattan Island, that tiny island not far off the American coast.

Ah yes ! October 1940 : menses mirabilis indeed.

It is almost as if May 1940, certainly one of the most 'menses horribilis' in all of Western Civilization, (followed by the August to September 1940 aborted invasion of England : half horribilis half mirabilis), seemed to have drawn out extraordinary efforts from various North American scientists deeply emotionally affected by the events in Europe but too old to be called to actively take up a rifle.

Because one of the things those three extraordinary laboratory efforts in October 1940 have in common is their sheer physicality - scaled up to pilot plant size before table top work had even started; dirty, tiring, dangerous work.

Literally, not just figuratively, fighting for results in the trenches of science.

So, if in October 2010, we mark the 70th anniversary of the start of the financial recognition for (a) George Laurence's efforts to build an atomic pile, and (b) Henry Dawson's start in his efforts to cure SBE with natural penicillin injections, we might as well add (c) the formal start of Oswald Avery and Colin MacLeod's efforts to determine the chemical nature of Henry Dawson's Transforming Principle - proving it to be DNA.

Did we say 'North American scientists' ??

Let it stand.

We all know that we here at the Arcadian Recorder also mean 'Nova Scotian-born scientists', but let that remain our little secret.....
