Comment utilisez-vous les nouvelles technologies dans la recherche ?
6:24
Bon, là, on touche le, le sujet qui m'est cher, hein.
6:26
C'est la vie du chercheur dans le laboratoire.
6:28
Parce que moi-même, j'étais chercheur en laboratoire.
6:31
Je le suis toujours un peu, mais différemment.
6:33
Il y a deux grands sujets pour nous.
6:34
C'est— le premier sujet, c'est : comment est-ce qu'on aide les chercheurs, parce qu'on a beaucoup de chercheurs en, en recherche avancée, à découvrir des nouvelles molécules.
8:46
Alors concrètement, des produits ont été créés grâce à l'IA et lesquels ?
12:02
Mm-hmm.
12:02
And he created this, uh, new hair color type, uh, for the market, uh, in France.
12:07
And then little by little, it has been always a very scientific company.
12:10
So if you look a little bit at key facts, we invented sun filters in the 1930s.
12:16
Uh, there was a very, very big milestone where we also invented not only product, but a reconstructed skin-So in, if you look at 1979, we've been... created this reconstructive cream that helped us to go out of animal testing very fast, and by the way, uh, before the law even asked it to cosmetic companies.
13:55
Mathieu said that the collaboration began with simple conversations.
13:59
So if you look at the way IBM entered into L'Oréal labs, it start by interviewing people.
14:06
What would help you to do your job? What is your business needs? So it was, by the way, uh, two months ago, a long series of interviews, and from all the people around the world we have in research, in Brazil, in India, in China, Japan, US, France of course.
