Criteria when person is officially dead.

I ask this question because of my research experience will behaviour of human lymphocytes in cell culture at the Kidonan Institute of Gerontology- a private non profit research Lab I set up in December 1974 during my early years of Medical practice.

To discuss the  history of this private non profit research Lab you have to go  back to July 1965- actually 1961- the year after I graduated from Medicine from U. of Manitoba in 1960 and had done  a one year rotating internship at St. Boniface General Hospital, Upon completing my rotating internship I was invited by the University of Saskatchewan in Saskatoon to join their newly formed Department of Cancer research as a cell biologist with the rank of Asst. Professor.. At this Cancer Research Lab they had  just hired Dr. Joesph Morgan – from the Connaught Research Lab in Toronto where together with Dr. C Parker they perfected the tissue culture techniques to grow human polio virus in tissue culture and enabled Dr. Salk to developed the polio vaccine for which he received the Nobel Prizefor Medicine..This enabled me to perfect the techniques of tissue culturegrowth of human tissue  Not only did I he esearch LOver the next 4 years I when I set up the Winnipeg Clinic Research Institute  Laboratory at the Winnipeg Clinic on the invitation  by Dr. PHT Thorlakson.  I was invited by theU. of Saskatchewan to work as a cel biologist in their newly established Department of Cancer Research in 1961 to set up a private Research Labmat the Winnipeg Clinic.

Can fingerprint from deceased person be used to unlock their iPhone ?

There are 3 basic ways to open your iPhone: 1)typing in the 4 number password code, 2)using your finger print. 3) using Siri- I haven’t tried Siri but theoretically it should work since you can ask Siri to do many things-all you need is the recording of your voice on file and/or in your “will”. Scenarios where being able to unlock cell phones include where a person dies suddenly and did not leave password and other data in their will or in cases of terrorism where the victims involved are killed by the police, and companies like the recent experience with apple where they refused to unlock the phone of such victims for the police. The idea occurred to me that maybe their fingerprints could be used to open their iPhone devices if they had installed this method to unlock their cell phones . One would easily test this hypothesis by going to a funeral and/or post mortem room and place the thumb of the deceased on the home button of their iPhone – or whichever finger they used for opening their iPhone when they were alive. .If it is not successful, I wonder whether fingerprints found in police files could replace the fingerprint method for opening iPhones or similar devices. Maybe the finger print is altered shorty after death by rigour mortis changes. A note of caution to the police : when killing the suspected terrorists they should try and save the upper extremities especially the fingers and/or thumbs before they blow them up!
