She sounds like a Nobel Prize future candidate herself: at 17 y.o. she created a device that lets the physically disabled to operate machinery, and got to world championships in science in the same year.
But in the 2007 Nobel Prize Ceremony, she will only be an attendant, not a recipient.
Ana Karen Becerra Duarte, now 18 y.o., is a freshman at a private Med School in Baja California, and the only Mexican in a group of 24 wold students to attend the ceremony in Stockolm, Sweeden, according to a story in Frontera,info, Tijuana's local daily.
The story does not explain who selected her, or what was the process, though her merits seem obvious.
