L'ETUDE : Food and Chemical Toxicology
This article has been retracted: please see Elsevier Policy on Article Withdrawal ( The journal Food and Chemical Toxicology retracts the article “Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize,” which was published in this journal in November 2012. This retraction comes after a thorough and time-consuming analysis of the published article and the data it reports, along with an investigation into the peer-review behind the article. Very shortly after the publication of this article, the journal received Letters to the Editor expressing concerns about the validity of the findings it described, the proper use of animals, and even allegations of fraud. Unequivocally, the Editor-in-Chief found no evidence of fraud or intentional misrepresentation of the data. The Editor-in-Chief again commends the corresponding author for his willingness and openness in participating in this dialog. Related:  Experiments, Ethics & Society

Oui, les OGM sont des poisons ! (Cet article paraît dans le "Nouvel Observateur" daté du 20 septembre 2012) C’est une véritable bombe que lance, ce 19 septembre à 15 heures, la très sérieuse revue américaine "Food and Chemical Toxicology" - une référence en matière de toxicologie alimentaire - en publiant les résultats de l’expérimentation menée par l’équipe du français Gilles-Eric Séralini, professeur de biologie moléculaire à l'université de Caen. Une bombe à fragmentation : scientifique, sanitaire, politique et industrielle. Elle pulvérise en effet une vérité officielle : l’innocuité du maïs génétiquement modifié. Lourdement toxique et souvent mortel Même à faible dose, l’OGM étudié se révèle lourdement toxique et souvent mortel pour des rats. En 2006, c’est comme un véritable thriller que commence cette recherche, dont le maître d’œuvre, Gilles-Eric Séralini, divulgue lui-même les conclusions dans un ouvrage à paraître la semaine prochaine ("Tous cobayes !"

Edheads - Activate Your Mind! Brazil nuts nutrition facts and health benefits Amazon's forest holds some of the unique plant species like Brazil nuts, acai berry, etc., that can be found nowhere else on the planet earth. Native Amazonian cherished these delicious nuts since ages, which provide them much-needed protein, fats and other essential nutrients. Botanically, brazil-nut tree belongs within the family of Lecythidaceae, of the genus: Bertholletia. Scientific name: Bertholletia excelsa. Brazil nut trees are found conspicuously in the non-flooded forest regions of Brazil, Bolivia, and Peru. Each mature tree bears up to 300 fruit pods in a season. Internally, each fruit features 10-25 seeds arranged in orange-like segments. Health benefits of Brazil nuts Brazil nuts are high in calories, contains good quantities of vitamins, anti-oxidants and minerals. Brazil nut oil, obtained from these nuts, has many traditional medicinal applications as emollient and massage therapy.

Les OGM ont perdu contre les mauvaises herbes L'Académie américaine des sciences organisait le 10 mai un sommet sur les plantes génétiquement modifiées résistantes aux herbicides. Une réunion de crise. Les agriculteurs américains ont l'impression d'avoir été floués par les semenciers qui leur avaient dit qu'avec les OGM résistants aux herbicides ils n'auraient plus jamais de problèmes avec les mauvaises herbes. Il leur suffisait de pulvériser du glyphosate - une molécule créée par Monsanto aujourd'hui dans le domaine public - pour être tranquilles. Un seul passage était nécessaire pour tout détruire sauf les cultures dotées d'un gène de résistance. Les mauvaises herbes deviennent résistantes elles aussi au Roundup, elles se multiplient très vite et envahissent les champs de soja, de maïs, de coton et de colza. Chaque année, de nouvelles plantes sauvages développent des résistances. Graves conséquences Des alternatives aux OGM sont d'ores et déjà recherchées. » OGM: l'UE pourrait annuler l'interdiction du MON 810

Shock study, replicates Milgram's findings Nearly 50 years after the controversial Milgram experiments, social psychologist Jerry M. Burger, PhD, has found that people are still just as willing to administer what they believe are painful electric shocks to others when urged on by an authority figure. Burger, a professor at Santa Clara University, replicated one of the famous obedience experiments of the late Stanley Milgram, PhD, and found that compliance rates in the replication were only slightly lower than those found by Milgram. And, like Milgram, he found no difference in the rates of obedience between men and women. "People learning about Milgram's work often wonder whether results would be any different today," Burger says. Milgram found that, after hearing the learner's first cries of pain at 150 volts, 82.5 percent of participants continued administering shocks; of those, 79 percent continued to the shock generator's end, at 450 volts. —K.I.

Good luck!

9 CRITIQUES, 9 réponses sur l'étude de Séralini Après la publication de l’étude de Gilles-Eric Séralini, première étude sur la vie entière de rats nourris au maïs NK 603 et qui fait apparaître la toxicité de cet OGM sur ces rats, de nombreuses critiques et questions se sont fait jour sur les conditions de réalisation de l’étude et sa crédibilité. Le Dr Joël Spiroux, co-auteur et directeur adjoint de l’étude, président du Criigen (Comité de recherche et d’information indépendant sur le génie génétique), répond. Première critique : 200 rats est un trop faible échantillon pour une étude solide… - L'échantillon des 200 rats, 20 rats par lot, correspond au nombre de rats utilisé par Monsanto dans son étude sur trois mois. En revanche, nous avons étudié beaucoup plus de paramètres toxicologiques. Le type de rats employé, les "Sprague-Dawley", est connu pour développer facilement des tumeurs… - Oui mais ce sont les lignées de rats utilisés dans le monde entier pour les recherches toxicologiques. - Détrompez-vous. - Absolument faux.

Walking Through Doorways Causes Forgetting We’ve all experienced it: The frustration of entering a room and forgetting what we were going to do. Or get. Or find. New research from University of Notre Dame Psychology Professor Gabriel Radvansky suggests that passing through doorways is the cause of these memory lapses. “Entering or exiting through a doorway serves as an ‘event boundary’ in the mind, which separates episodes of activity and files them away,” Radvansky explains. “Recalling the decision or activity that was made in a different room is difficult because it has been compartmentalized.” The study was published recently in the Quarterly Journal of Experimental Psychology. Conducting three experiments in both real and virtual environments, Radvansky’s subjects – all college students – performed memory tasks while crossing a room and while exiting a doorway.

How Samsung is out-innovating Apple Mobile-gadget rivals are leapfrogging Apple with useful features not on iPhones, iPadsThis success is most apparent with Apple's biggest mobile rival, SamsungSamsung is more nimble than Apple at improving its devices through software updatesWith Galaxy Note, Samsung has a category of phone people didn't know they wanted (CNN) -- There's no arguing that Apple set the standard for modern mobile devices with the iPhone and the iPad. It didn't take long after those two products launched for competitors to rush out their own copycat devices. Even then, it took another few years before Android was good enough to go toe to toe with iOS, Apple's mobile operating system. But it's no longer about being just as good as Apple. You have to be better. The evidence is everywhere, but it's most apparent in products made by Apple's biggest mobile rival, Samsung. Samsung's sprawling empire Apple CEO remains confident with company Mark Cuban not bullish on Apple None of that mattered.

Faiblesse des études de mise sur le marché PARIS (AFP) - Le chercheur Gilles-Eric Séralini et la députée européenne Corinne Lepage ont critiqué mardi "l'extrême faiblesse" des études sur lesquelles reposent les autorisations de mise sur le marché délivrées au niveau de l'UE pour les OGM. Tous deux participaient à une conférence de presse de l'organisme de recherche sur les OGM Criigen (Comité de recherche et d'information indépendantes sur le génie génétique), dont ils sont membres fondateurs. "Les critiques qui ont été faites à l'encontre de l'étude du Pr Séralini, elles devraient aussi être appliquées aux études qui ont permis la validation des OGM et dont on constate l'extrême faiblesse", a déclaré Corinne Lepage. Gilles-Eric Seralini, professeur de biologie moléculaire à Caen, est l'auteur d'une étude controversée sur la toxicité des OGM faite sur des rats, sur une durée inhabituelle de deux ans. Le maïs NK603, de la firme Monsanto, est un maïs transgénique résistant à l'herbicide Roundup, produit par le même fabriquant.

Stanford Prison Exp IT BEGAN WITH AN AD in the classifieds. Male college students needed for psychological study of prison life. $15 per day for 1-2 weeks. More than 70 people volunteered to take part in the study, to be conducted in a fake prison housed inside Jordan Hall, on Stanford's Main Quad. The leader of the study was 38-year-old psychology professor Philip Zimbardo. He and his fellow researchers selected 24 applicants and randomly assigned each to be a prisoner or a guard. Zimbardo encouraged the guards to think of themselves as actual guards in a real prison. The study began on Sunday, August 17, 1971. Forty years later, the Stanford Prison Experiment remains among the most notable—and notorious—research projects ever carried out at the University. The public's fascination with the SPE and its implications—the notion, as Zimbardo says, "that these ordinary college students could do such terrible things when caught in that situation"—brought Zimbardo international renown.

Theresa May: Home Secretary vows to crush judges' revolt by rushing through tough new laws By Theresa May Unless there are very exceptional circumstances, foreigners who have committed serious crimes in this country, or who have attempted to cheat the immigration system, should be deported from Britain. Parliament wants that to happen, the public wants that to happen, and I want that to happen. But, too often, it is not happening. It is not in the national interest that this situation continues. Fight: The right to family life is not an absolute right, it is a qualified right, says the Home Secretary This means that if a foreign criminal can show that he has a family in this country, they take the view he has a right to remain here, regardless of the gravity of the offences. That interpretation is wrong. I thought that possibly the problem for the judges was that our Parliament had not explicitly stated how the right to family life could be restricted. So in June last year I ensured that the House of Commons was able to debate my amendments to the immigration rules.

Lepage, Royal, Voynet : "Ministres de l'Environnement" Nous, anciennes ministres de l’environnement, avons pris connaissance de la polémique née de l’étude du professeur Séralini. Nous nous réjouissons de la volonté exprimée par le gouvernement, dans la ligne de la décision du conseil des ministres de l’environnement de l’UE de 2008, de remettre à plat les systèmes d’évaluation des OGM et des pesticides et d’exiger des tests de toxicité à long terme, donc sur vie entière de l’animal. Il est également indispensable que soient rendues publiques toutes les études existantes sur l’impact des OGM sur la santé ainsi que les données brutes (c’est -à- dire les résultats des analyses et des mesures) pour qu’un véritable débat scientifique puisse s’ouvrir au sein de la communauté scientifique dans son ensemble. Nous tenons à rappeler notre attachement au principe de précaution qui doit l’emporter sur la présomption de non toxicité de ces produits. Ségolène Royal Corinne Lepage Dominique Voynet

Improbable research: The Limerick laureate works his magic In 2003, an independent scholar from New Jersey began submitting limericks for a competition in mini-AIR, the monthly online supplement to my magazine, Annals of Improbable Research. The contest challenges readers to read an off-putting scholarly citation, and explain it in limerick form. Martin Eiger so consistently won that we eventually banned him as an unfair competitor, gave him the title Limerick laureate, and now publish him every month. He handles a huge range of subject matter. An early Eiger limerick summarised a Japanese study called Pharmacological Aspects of Ipecac Syrup (TJN-119) - Induced Emesis in Ferrets: If you're hoping to hash out a thesis,And stuck for a topic: emesis,As triggered in ferretsUndoubtedly meritsMuch more than a mere exegesis. Warwick University mathematician Jonathan Warren's 1999 treatise On the Joining of Sticky Brownian Motion includes a three-page proof of the Non-cosiness of Sticky Brownian Motion.
