Essentially what that says, is, take a chimp brain foetally, and let it go two or three more rounds of divisions and you get a humain brain instead. And outcomes symphonies, and ideologies, and hopscotch there. What that tells you is, with enough quantity, you invent quality. — Robert Sapolsky, février 2011. Réponse à la […]

Photo: Serge Brunier (TWAN), depuis la Tour Montparnasse. — Astronomy Picture of the Day. On les voyait clairement depuis ma terrasse avec Max, en attendant le début de Top Chef, je me demandais ce que c’était (Max penchait pour une planète Melancolia-style), jusqu’à ce que sa proprio nous éclaire quelques jours après. — Best Venus-Jupiter conjunction in […]
In a study published online today in Science, the researchers show that in mice, exposure to microbes in early life can reduce the body’s inventory of invariant natural killer T (iNKT) cells, which help to fight infection but can also turn on the body, causing a range of disorders such as asthma or inflammatory bowel […]

Prof et nouvelles technologies
Sur 65 élèves, 51 élèves – soit plus des trois-quart – ont recopié à des degrés divers ce qu’ils trouvaient sur internet, sans recouper ou vérifier les informations ou réfléchir un tant soit peu aux éléments d’analyses trouvés, croyaient-ils, au hasard du net. (…) Je crois qu’avec cette expérience pédagogique j’ai d’abord démontré aux élèves […]
I have difficult news. We’ve learned that Mike Daisey’s story about Apple in China – which we broadcast in January – contained significant fabrications. We’re retracting the story because we can’t vouch for its truth. This is not a story we commissioned. It was an excerpt of Mike Daisey’s acclaimed one-man show “The Agony and […]
Non seulement ils font grossir, augmentent les risques cardio-vasculaires et sont liés à une augmentation des risques de cancer (du sein, par exemple), mais ils dégradent aussi notre humeur et la qualité de notre sperme (bon, ce dernier point, j’avoue que je m’en carre, mais quand même). This study provides the first evidence linking dTFA […]

Les leçons à tirer des films catastrophes
Their special effects can be realistic enough to make us feel like we are right there in the heart of the storm. But frequently, the heroes and heroines of these movies respond to disasters in ways that bear no resemblance to what people in the real world should do. We can nevertheless use disaster films […]

Les limites de TED
But: We live in a world of increasingly networked knowledge. And it’s a world that allows us to appreciate what has always been true: that new ideas are never sprung, fully formed, from the heads of the inventors who articulate them, but are always — always — the result of discourse and interaction and, in […]

Avortement après naissance
Alberto Giubilini, from Monash University, and Francesca Minerva, from the University of Melbourne, say a foetus and a newborn are equivalent in their lack of a sense of their own life and aspiration. They contend this justifies what they call ”after-birth abortion” as long as it is painless, because the baby is not harmed by […]
