Protein Dynamics in Transition
A Critical Review of Bio-Neutron Scattering Literature
by Wolfgang Doster


The title of this site refers to a paper by Doster et al. Nature (1989) which created a big wave of publications on this topic. While the main topic of my paper was inelastic neutron scattering, most subsequent papers reduce the subject to pure elastic scattering and mean square displacements, which I call "displacementology". The purpose of this site is to address the unusually large number of publications in this field, which are seriously flawed or are intended to be misleading. This concerns in particular major journals like Physical Review Letters, PNAS or Science. This field has been captured by a bunch of insiders, which support each others publications as referees, but never question their work. Essentially only supportive work is referenced. Authors, which discuss the work of insiders critically like me are excluded from the inner circle and are treated as outsiders, which can be ignored. As a consequence, even insider papers, which are totally obsolete, are often cited as being ingenious, like the Zaccai Science 2000 paper (Smith, PRL 2017). This attitude slows down progress in the field dramatically . In 2002 one of the insiders, Joe Zaccai, told his collaborators, that for the future, Doster et al. will no longer be cited by them. In 20 years I never had the pleasure to review a single of the many papers published by Zaccai, in a field, which I have created, and although he constantly used and misused my ideas. He could succeed only by excluding expertise. During the last 10 years bioneutron scattering came under the control of the Hans Frauenfelder network and his energy landscape paradigm. This can be deduced from any citation list of insider papers. Most HF papers are completely unrelated to neutron scattering, until recently. The top thing is that Frauenfelder now questions even well established scattering theory, because it seems not compatible with his ELM. Why he is wrong and to argue against other nonsense, I critically review a small selection of his and other publications which are flawed in my view. It is not clever to ride a dead horse. Anyway this is a modest attempt to reestablish a dead scientific discussion. The money wasted with these big machines for meaningless science is enormous.
