This neutron-scattering study carried out at the Intense Pulsed Neutron Source, Argonne National Laboratory, produced data for a model that shows peptides (cylinders) inserting themselves in holes they form in a cell membrane.

12. Around 3000 BP, the biggest change is not the appearance of ceramic. The major revolution is the rapid establishment of a large network known as the Meadowood interaction sphere. Norman Clermont published the cemetery at Pointe-du-Buisson in 1978 and the latest addition for this time period comes from the Quebec City area. Yves Chrétien excavated a small component with a particular Early Woodland ritual including close to two hundred quaternary blades made of typical Onondaga chert. These offerings indicate that the inhabitants of the Quebec City area were participating in the Meadowood network. Neutron activation analysis of Vinette 1 ceramic fragments from Pointe-du-Buisson has revealed that the majority of the samples were obtained through that network and not produced with the local clay, which is considered by local potters as a very good source to make pots. As for the Middlesex funerary complex, investigated by Norman Clermont, it is still problematical culturally and chronologically.

14. Medicine Louis Pasteur's theory of germs is ridiculous fiction. (P. Pachet, Professor of physiology at Toulouse, 1872) 1930's - Sir James Chadwick discovers the neutron (Nobel Prize, 1935.) Cyclotrons are first used in trials to treat cancer using neutrons at the University of California at Berkeley. Trials are stopped when the cyclotron is needed for the war effort. 1960's - Diagnostic ultrasound is first used. Neutrons are shown to be effective in treating certain types of cancerous tumors, and begin to be used clinically. 1970's - The Neutron Therapy Facility at Fermilab is built and begins treating patients.
