Experimental duplication & critique

Need to find a balanced view of Krishna's research. So far, I found this bit:

"A short paper claiming an experimental confirmation of early Jeewanu works exists, although the issue whether the ‘microscopic objects’ were alive or not was left open (Briggs 1965). In contrast, the critique of biochemist Cyril Ponnamperuma (1923–1994), then a leading figure of NASA’s Exobiology Division, was fierce and probably influential. Together with coworker Linda Caren, he lamented the ‘confusing manner in which the experimental procedures [of the Jeewanu work in general, MG] were presented’; they questioned the sterility of the mixtures and speculated that multiplication of the particles could have resulted from mechanical breakage by shaking (Caren and Ponnamperuma 1967, quote p 3). In the same vein, the team demurred that ‘the large number of chemically undefined substances in the protenoid jeewanu experiments preclude a meaningful interpretation’ (l.c., p 4). It should be noted, however, that the paper only reviewed, compared and re-interpreted data published by Bahadur or others and did not refer to any attempt of the authors to reproduce the work. Accordingly, Caren and Ponnamperuma concluded that ‘[At] present, the nature and properties of the jeewanu remains to be clarified’ (l.c., p.4).iii "
