A team at Northwestern University in Chicago is conducting the experiments, which allow researchers to see details of the mummy’s insides without removing its delicate wrappings. The team is hopeful that the results could help to predict [bone fractures](http://time.com/3558795/osteoporosis-men/) before they happen. “We have some preliminary findings about the various materials, but it will take days before we tighten down the precise answers to our questions,” said experiment leader Dr. Stuart Stock, research professor of Cell and Molecular Biology at Northwestern, in a [statement](http://news.feinberg.northwestern.edu/2017/11/northwestern-explores-mummys-secrets-with-particle-accelerator/). “I wanted to compare populations who had an active lifestyle with our more modern sedentary populations,” Stock said. “Is there a difference in bone quality?” Current medicine, he said, can only predict bone fractures with 80% certainty. If this experiment proves successful, he hopes that certainty might raise to 95%. According to Stock, bones contain a high density of nanocrystals, which scatter X-rays in different directions depending on the way they are arranged. Examining the sample with an X-ray allows scientists to interrogate the bones’ structure. “If you know the angles and relative intensities of these diffracted beams, then you can identify what material it is — it’s like a fingerprint,” Stock said. “As far as I know, no one has tried to non-invasively interrogate what’s inside an object like this.” ## Transcript Someone sends me their cat or their puppy, I ask them the animal's name. I call it by name the whole time. So I have an enormous amount of respect and integrity for the animal. [ MUSIC ] I'm the Sorceress Cagliastro. I do basically pet mummification for animals who are under 20 pounds. [ MUSIC ] I look at the animal and I decide whether I will be able to create a, a vision of the animal in a form that looks similar to what it would look like while alive. For example this is a mummified bullfrog. This is a caiman, this is a baby caiman. [ MUSIC ] And the individual does not want the tail concealed within the main wrapping. She wanted the tail to be a separate entity because the tail was sort of her favorite part. I have an enormous, almost confusing, following in Texas. I've climbed to California, in Maine, in Washington state. [ MUSIC ] There's only five or six states that I haven't had tax from at this point. My clientèle is more than 60 % male, which I find very interesting. Men have expressed more of an interest for the permanence for a situation where their animals become permanent and in their home. [ MUSIC ] The basic tenant amongst all clients is that they, they made a decision that the animal's going to stay with them in their home and that cremation is not a choice that they're interested in. About 20 years ago, I worked for the office of the Chief Medical Examiner. I was an autopsy tech. [ MUSIC ] I got a license in Forensic reconstruction. We'd get the skull and put the face back on using clay and markers. It didn't provide for me the joy that I was hoping it would provide. Although, I was very interested in the preservation of flesh. [ MUSIC ]. The reality is, that no matter how much information we have from ancient Egypt, no one has presented a manual of mumification. When you think about the book of the dead, The book of the dead is really called the book of coming forth by day. And so much it is a list of spells and procedures to allow one to become reanimated in the afterlife. So there is almost nothing about mummification. [ MUSIC ] So what I did was I worked with some chemistry students and we got together and we figured out. Over multiple years about ten years of, of experimenting with rotting pieces of meat, what we could preserve and what we could not. I now have what I call my secret formula of ten salts and six metals and creates this experience called [ SOUND ] mummified remains. I have one celebrity client which I can't talk about. And I have one client who intrigues me endlessly. She will be my first human mummification. She's terminally ill. I've mummified three of her pets. [ MUSIC ] She has built a temple in her home in Arizona and she will, would like to be laid out like the wife of a pharaoh, and it is my intention to mummify a human within the next 16 months. I am fascinated with the process of death. [ SOUND ] Death to me is someone in the room whom I need to have a conversation with. For me, death is an ex, exploration, it's brilliant. It's magnificent and it's the one thing we all share animal, vegetable, human it doesn't matter. We're all going to share this.
