Otzi is an endlessly fascinating subject. I have used him in my classroom before and wrote a post about it last year. Researchers never cease looking for new discoveries and in just the past few months issued new findings based on studies of Otzi's stomach contents right down to what they learned from examining the pollen recovered on the surface of the food. It is impressive that even 27 years later, there are new things to be learned. Because the studies of Otzi are well funded and well managed these new techniques will likely be useful for other mummified remains across the world. I updated the post today and though it is focused on teaching, there is a lot of information that should be of general interest.
