Dig into the Irish myth of lovers Gráinne and Diarmuid, and follow their journey as they flee from her betrothed, Fionn.--Gráinne, princess of Tara and bride-to-be, was furious. She had thought she was betrothed to a young soldier, bold and brilliant enough to be her equal. Yet it soon became clear she was expected to marry Fionn, a warrior far past his prime. Not willing to suffer this insult, Gráinne decided that before the wedding she would exact her revenge. Iseult Gillespie shares the Irish myth of Fionn's fury.Lesson by Iseult Gillespie, directed by Efa Blosse-Mason.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/love-vs-honor-the-irish-myth-of-diarmuid-s-betrayal-iseult-gillespieDig deeper with additional resources: https://ed.ted.com/lessons/love-vs-honor-the-irish-myth-of-diarmuid-s-betrayal-iseult-gillespie#digdeeperAnimator's website: http://www.efabmanimation.com and http://paolorussoanimation.weebly.com----------------------------------------------Thank you so much to our patrons for your support!

Investigate the science behind how doctors use radioactive drugs and PET scans to detect and diagnose diseases like Alzheimer’s and cancer.Uploaded 19-03-19--Is there a way to detect diseases like cancer and Alzheimer’s before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can detect the spread of diseases before they can be spotted with other types of imaging. So how exactly does this work, and is it safe?
