Queen Sofía nominated for Nobel Peace Prize

It was reported this week that Queen Sofía of Spain, the mother of King Felipe VI, has been nominated for the Nobel Peace Prize. The Queen, whose husband King Juan Carlos I abdicated last year, has been nominated by representatives of an undisclosed American university for her commitment to research into Alzheimer's disease and for her work on behalf of the disabled and other marginalised groups.
The nomination was revealed by the head of Spain's Centre of Investigation into Neurological Diseases (CIEN) on World Alzheimer's Day on Monday. However, it was not clear whether the nomination has just been made or if Queen Sofía was nominated for the 2015 Nobel Peace Prize before the deadline for nominations expired on 31 January.
The recipient or recipients of this year's Nobel Peace Prize will be announced on 9 October, but there are hundreds of nominees and I would say it is highly unlikely that Queen Sofía would be seriously considered. The Nobel Peace Prize Committee has in recent years expanded the peace concept somewhat, which has resulted in the Peace Prize being awarded for for instance environmental work or the promotion of girls' rights to go to school, but supporting medical research seems to be too far-fetched to be covered by any definition of peace (it seems to be a general misunderstanding that all sorts of good deeds can be rewarded with the Nobel Peace Prize).
The European royal who is known to have come closest to receiving the Nobel Peace Prize is Prince Carl of Sweden, who was President of the Swedish Red Cross for forty years and was on a number of occasions seriously considered based on his humanitarian work.
