L'article faux qui a rapporté 1,4 million de visites à BuzzFeed - Capture d'écran de BuzzFeed - Au lieu de faire quelque chose de productif comme finir le deuxième chapitre de mon livre (c'est en bonne voie de toute façon), j'ai passé une heure ce mardi 3 décembre à regarder comment l'Internet s'était fait avoir par un nouveau canular. Elan Gale, un producteur de The Bachelor et donc une des pires personnes de la planète, a passé une partie de son Thanksgiving à live-tweeter ce qu'il affirmait être une querelle avec une femme irritante portant «des jeans de maman» qui se plaignait trop bruyamment du retard de son avion. Gale lui a envoyé des boissons et des petits mots pour lui dire de se taire et de «manger une bite» («eat a dick» en anglais, expression utilisée pour répondre en marquant son énervement à une attaque verbale). publicité Internet a adoré, surtout BuzzFeed. Problème: l'histoire de Gale n'était pas vraie. BuzzFeed s'est moqué de moi Je ne dis pas que BuzzFeed devrait virer qui que ce soit. Malheureusement fréquent «Trop bon pour vérifier»
Santé - Des chercheurs mettent en lumière les vertus du sirop d’érable Connexion Pauline Gravel 7 octobre 2013 Société / Actualités en sociétéSanté - Des chercheurs mettent en lumière les vertus du sirop d’érable Photo : Jacques Nadeau - Le Devoir Le sirop d’érable regorge d’antioxydants qui aident les cellules à absorber rapidement le glucose, dotant du coup ce produit du terroir d’un faible indice glycémique. Des études effectuées à INAF ont en effet révélé que le sirop d’érable était plus riche en polyphénols que le sirop de maïs, le sirop de riz brun et le sucre blanc. Rappelons que les polyphénols sont de puissants antioxydants ayant la capacité de réduire le stress oxydatif qui est à l’origine des maladies proinflammatoires, comme le diabète de type 2, l’obésité et les maladies cardiovasculaires. Le sirop d’érable s’est par ailleurs démarqué de tous les autres sucres par le fait qu’il renferme de l’acide abscissique et de l’acide phaséique, qui sont produits par l’érable pour combattre le stress causé par l’environnement.

How snowflakes get their shape The key is here: each branch on a single snowflake experiences the same history of variations as it falls, but different flakes don't. The thing with (classical) physics is that if you start with identical starting conditions, and subject something to the same conditions, you get the same outcome. But isn't it amazing that the snowflake is small enough that even then there are no variations on the conditions each of the six branches experiences?! It is amazing :D Snowflakes are such a weird size, really — just big enough that we can see them, but as you said, small enough to act like a "particle" when you consider its environment.
Eau d'érable sur les tablettes: encore du travail à faire | Étienne Fortin-Gauthier | Agroalimentaire Depuis dix ans, plusieurs millions de dollars ont été investis dans le développement de ce produit, afin de trouver les meilleures méthodes permettant de récupérer, de traiter et de distribuer à grande échelle l'eau sucrée qui s'écoule lentement des érables de nos forêts. «Même si c'est de l'eau d'érable, c'est un produit très complexe à développer. Entre 2 et 3 millions $ ont été investis par notre organisation et par le gouvernement dans la recherche et le développement. Nous croyons énormément en ce produit», soutient Paul Rouillard, directeur adjoint de la Fédération des producteurs acéricoles du Québec. En entrevue à La Presse Canadienne, il révèle qu'environ un million de litres d'eau d'érable seront distribués sur le marché cette année. Trois entreprises, Maple3, Oviva et Seva, ont obtenu le mandat de commercialiser et faire connaître l'eau d'érable aux consommateurs d'ici et de par le monde. «Nous partons de zéro.

Listen to Isaac Asimov in 1988, explaining why scientists rule Each generation informs the next, a larger public belief in the mystical only hinders our progress as we return to that which we have ruled out as possible, many of these belief systems insisting that their followers act on blind faith and follow doctrine without question. A return to tradition only stifles progress as we are tempted to continue centuries old conflicts started by men long dead. It makes me sad to know that I shared the world with Issac Asimov and Carl Sagan and other great minds before I was aware of them or the brilliance of their vision and now that I have learned to respect them they are no longer here to admire. I am however grateful that they have left us with documents such as this interview where they speak from the heart for the coming generation that is ready to listen.

The future of nukes: Even if everything goes wrong, nothing happens GOTHENBURG, SWEDEN—Carlo Rubbia, Nobel Prize winner and former Director General of CERN, has spent his more recent career thinking about energy, and he has some strong thoughts on nuclear power. Those thoughts have been driven in part by climate change (nuclear provides the only source of low-carbon electricity that can be deployed anywhere), but they've also been driven by the events at Fukushima. At least twice during a Nobel Dialog panel, Rubbia said that the sort of risk analyses that we've been doing for nuclear power are simply insufficient. The analyses are based on probabilities: if the failure of a given pump creates an obvious risk, you simply put in a second pump, then a third if necessary. In the end, you get an infinitesimal risk that you can approximate as zero. In its place, Rubbia said that we need to have some form of design that makes safety deterministic—something where, even if things go completely wrong, nothing happens. He's hedging his bets.
Le repas, un art français LE MONDE CULTURE ET IDEES | • Mis à jour le | Par Anne Chemin C’est un petit miracle qui s’accomplit tous les jours sous nos yeux sans que nous y prêtions la moindre attention. Le matin, à midi et le soir, des dizaines de millions de Français décident, à la même heure, de se réunir autour d’une table pour partager un repas, comme si un chef d’orchestre invisible donnait le signal du début des festivités. Ce rituel est si bien ancré dans nos mentalités que nous le jugeons banal, voire normal. Notre modèle alimentaire est en effet très singulier. « Le quotidien des Français est fortement rythmé par les trois repas traditionnels, constate Thibaut de Saint Pol, sociologue à l’Ecole normale supérieure de Cachan. 3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production | Autopia Engineer Jim Kor and his design for the Urbee 2. Photo: Sara Payne Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles. If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced. His creation is called the Urbee 2 and it could revolutionize parts manufacturing while creating a cottage industry of small-batch automakers intent on challenging the status quo. Urbee’s approach to maximum miles per gallon starts with lightweight construction – something that 3-D printing is particularly well suited for. Jim Kor is the engineering brains behind the Urbee. “We thought long and hard about doing a second one,” he says of the Urbee. Kor and his team built the three-wheel, two-passenger vehicle at RedEye, an on-demand 3-D printing facility. Photo: Sara Payne “We’re calling it race car safety,” Kor says.
Animal protein-rich diets could be as harmful to health as smoking | Science A diet rich in meat, eggs, milk and cheese could be as harmful to health as smoking, according to a controversial study into the impact of protein consumption on longevity. High levels of dietary animal protein in people under 65 years of age was linked to a fourfold increase in their risk of death from cancer or diabetes, and almost double the risk of dying from any cause over an 18-year period, researchers found. However, nutrition experts have cautioned that it's too early to draw firm conclusions from the research. The overall harmful effects seen in the study were almost completely wiped out when the protein came from plant sources, such as beans and legumes, though cancer risk was still three times as high in middle-aged people who ate a protein-rich diet, compared with those on a low-protein diet. The study throws doubt on the long-term health effects of the popular Atkins and Paleo diets that are rich in protein. "Spend a couple of months looking at the labels on your food.
The Artificial Womb Is Born And The World of the Matrix Begins ”One by one the eggs were transferred from their test-tubes to the larger containers; deftly the peritoneal lining was slit, the morula dropped into place, the saline solution poured . . . and already the bottle had passed on through an opening in the wall, slowly on into the Social Predestination Room.” Aldous Huxley, ”Brave New World” The artificial womb exists. In Tokyo, researchers have developed a technique called EUFI — extrauterine fetal incubation. They have taken goat fetuses, threaded catheters through the large vessels in the umbilical cord and supplied the fetuses with oxygenated blood while suspending them in incubators that contain artificial amniotic fluid heated to body temperature. Yoshinori Kuwabara, chairman of the Department of Obstetrics and Gynecology at Juntendo University in Tokyo, has been working on artificial placentas for a decade. Kuwabara and his associates have kept the goat fetuses in this environment for as long as three weeks. Between Womb and Air
Fruit and vegetable intake: five a day may not be enough, scientists say | UK news Eating at least seven portions of fresh fruit and vegetables a day was linked to a 42% lower risk of death from all causes. Photograph: Jeff J Mitchell/Getty Images Five portions of fruit and vegetables a day – a familiar mantra for those concerned about their own and their children's health – may not, after all, be enough, according to a new report by scientists, who suggest we should instead be aiming for seven a day, and mostly vegetables at that. Alarmingly for some who thought they were doing the right thing, tinned and frozen fruit may not be helpful at all. The latest wisdom – guaranteed to raise a groan from those already perplexed over stories of suspect sugars and dodgy fats – arises from a study carried out by experts at University College London, who analysed the eating habits of 65,000 people, revealed through eight years of the Health Survey for England, and matched them with causes of death. Oyebode said she thought the Australian example was probably the one to follow.
MIT's shapeshifting display lets you reach out and touch someone MIT has demonstrated a "Dynamic Shape Display" that can physically change shape to render 3D content. As Fast Company reports, the display is called inFORM, and it's a large surface that sits atop a series of pins, actuators, and linkages. By moving each actuator, inFORM can move the pin it's attached to up or down, allowing for a wide range of interactions. A projector mounted above the surface provides context to the shapeshifting pins, giving them color and highlighting depth. In a video released by MIT, the table is shown moving a ball, mirroring a book, displaying 3D charts, and giving an extremely visible smartphone notification. When used in conjunction with a Kinect sensor, inFORM gets a lot more interesting. MIT says it's exploring "a number of application domains" for inFORM. It's extremely impressive stuff, but it's just one step on a long path to what MIT calls Radical Atoms.
