At TEDxYouth@Manchester, genetics researcher Dan Davis introduces the audience to compatibility genes — key players in our immune system’s functioning, and the reason why it’s so difficult to transplant organs from person to person: one’s compatibility genes must match another’s for a transplant to take.

The Effects of Time Revealed by People Posing Next to Photos Taken Decades Apart by Ana Oliveira

Identities by Ana Oliveira is a joyous exploration of the toll of time. Ana asked senior citizens to find their most treasured portraits from their young adulthood, and then she recreated the portraits in the modern time. The side-by-side display of the portraits is stunning. There is no doubt it is the same person as you see the similarities in bone structure and eyes, but time has played its games on each of the people. The eyes are the most telling part in each picture, where you can still see the love of life shining out, even though the faces have changed.

Identities I covers people in many different age ranges, but the most stunning portraits are of seniors where up to 60 years in time have elapsed from the original portrait.
