Jun 9, 2015 Dr Horace Drew speaking at UFO Research (NSW) Incorporated meeting held at Club Burwood, Burwood NSW Australia on 6 June 2015. ‘Crop pictures seem to be the marks made by time travellers: a brief summary of past work, and a presentation of the latest field images from April to early June of 2015′ – Dr Horace R Drew (Caltech 1976-81), MRC LMB Cambridge (1982-86), CSIRO Australia (1987-2010). My mainstream scientific research (1976-2010) focused on the structure of DNA, and its role in molecular biology and health. Our group at Caltech did the first structure at high resolution of normal right-handed DNA in 1980, by x-ray diffraction from single crystals (see http://www.pnas.org/content/78/4/2179.... We also co-discovered left-handed DNA (see http://www.nature.com/nature/journal/.... Later I wrote a graduate-level textbook on DNA with three colleagues from Cambridge, England (see http://www.sciencedirect.com/science/.... I first became interested in crop circles in 2002, when I attended a scientific meeting in Cambridge that dealt with the wrapping of DNA into chromosomes. Two weeks before this meeting took place, a major subject of our discussions (called the nucleosome core) was drawn in a field near Crooked Soley, partway between Avebury and Cambridge (see http://www.cropcircleconnector.com/an.... After that strange incident, I began to study those enigmatic field images as any good scientist would do. I gradually learned how to understand their intellectual content and codes, which depend not only on patterns in the flattened crop, but also on features of the landscape nearby. It slowly became clear that all of the ‘real’ crop pictures were being made by advanced ET scientists of various kinds (physics, math, chemistry, astronomy or biology), who possess intelligence and knowledge far beyond our own. Such artistic images are designed to be seen from high in the air, or even from space. Thus all of (i) aerial photography, (ii) Google Earth and (iii) ground photography are required to assess their meanings. For current information, please go to the Crop Circle Connector website, by googling ‘crop circles 2015′. Some of their field pictures show partial images of the future, although they do not predict the future per se (see http://www.cropcircleconnector.com/an.... There has been a fierce cover-up of this subject (along with UFO matters) in the mainstream media, and also on ‘respected’ internet sites such as Wikipedia. As the result of this cover-up, 99.99% of the general public today do not know what is really going on. It is hard for them to accept that they have been lied to, by media authorities whom they unwisely trusted. Leading newspapers or TV stations lie blatantly about crop circles, without any ethical concern for telling the truth (see for example http://www.cropcircleconnector.com/an.... Major scientific journals print false information as their cover stories (see http://www.iop.org/news/11/aug/page_5.... My personal view is that the ‘crop artists’ represent a coalition of human or ET races who oppose the alien Greys. They warn about major problems for human civilization on Earth in the near future. Their longest text message was drawn in 2002 (see http://www.cropcircleconnector.com/an.... No group of human fakers have ever come close to reproducing that highly complex image, which appeared in less than four hours of English darkness during August. It pointed toward a radio transmitter nearby for BBC Winchester, and said in part: ‘We oppose deception’, meaning ‘lies told by the British press!’ Some of the best crop-circle puzzles or messages in history (up to 2011) were summarized here (see http://www.cropcircleconnector.com/an.... During the current summer season of 2015, farmers in England or Europe have become very aggressive toward intruders in their fields, and will call the police or prosecute anyone found there, for trespass and criminal damage. Thus the only fake crop pictures which we have seen, in recent years, were rare cases when someone paid the farmer for use of his field, typically L1000 to L2000 English pounds. Given such prohibitive conditions for making fake crop pictures, about one-third of the total number dropped out from the summer of 2013 onward, while most of the well-made ones which we see today in 2014 or 2015 appear paranormal and authentic, with a few exceptions.
