Recherche : Le chocolat engendre-t-il des tueurs en série ?

Le chocolat engendre-t-il des tueurs en série ?

 

Le 10 octobre dernier est parue dans le fort sérieux New England Journal of Medicine une étude qui a fait les délices de la presse généraliste. On y apprenait qu'il existait un lien de corrélation extrêmement significatif entre la consommation de chocolat par un pays et le nombre de prix Nobel que ledit pays décrochait. L'information a eu tant plus d'écho qu'elle a été publiée pendant la semaine où les Nobel 2012 étaient décernés. Tout en expliquant qu'une corrélation ne signifie pas forcément un lien de cause à effet, l'auteur de cette étude, Franz Messerli, fait tout pour en dénicher un ! Pour ce cardiologue, tout est dans les flavanols, des molécules antioxydantes présentes dans le cacao, dont plusieurs études ont montré qu'elles améliorent les fonctions cognitives. Tout se tient : les pays où l'on mange beaucoup de chocolat font des habitants plus intelligents et ont donc plus de prix Nobel. La possibilité que le lien de cause à effet soit inversé – dans les pays les plus intelligents et donc les plus comblés en prix Nobel, on sait les vertus bienfaisantes du chocolat sur la santé et on en mange davantage – est, selon Franz Messerli, concevable mais improbable[...]

Singapore to unveil world’s first ‘mechanical forest’ | SmartPlanet

Singapore to unveil world’s first ‘mechanical forest’ | SmartPlanet | Science, Technology, Medecine and Society | Scoop.it
Are massive power-generating supertrees the way of the future?

 

On June 29th, officials in Singapore will open to the public the world´s first mechanical forest. Located in in the Bay South garden, the one-of-a-kind park showcases a total of 18 man-made “supertrees,” massive structures towering as a high as 50 meters over the ocean bay.

 

In a way, the Gardens by the Bay project can easily be viewed as an indictment on the current state of humanity. The notion of an artificial forest feels like a sad commentary on how far removed from nature our societies have become. In actuality though, the 250-acre landscaping project may serve as a glimpse of exactly the kind of intervention that´s needed for people and the environment to not only co-exist, but also thrive.

Mental illness & Creativity : Art as a Symptom of Brain Disease

Mental illness & Creativity : Art as a Symptom of Brain Disease | Science, Technology, Medecine and Society | Scoop.it

In this article, Doctor of Philosophy from University of Melbourne and mental health research fellow India Bohanna tackles the link between creativity and mental illness:

"When we think of someone affected by a serious brain disorder, we imagine deterioration and loss of function, but a surprising new study shows that some people may actually develop artistic talent as a result of their brain disorder, and that in turn, their art can tell us about the nature of their brain disorder."

Retrodiagnosis: Rewriting Medical History

Retrodiagnosis: Rewriting Medical History | Science, Technology, Medecine and Society | Scoop.it

Retrodiagnosis is the practice of reexamining medical diagnoses from the past. With the help of current medical information, taking a fresh look at old, or even ancient, cases may confirm a historical diagnosis; if a different conclusion is reached, this may shed new light on our interpretation of history. Currently, investigators are looking again at a more recent death: that of Palestinian leader Yasser Arafat. If the cause of death is found to be poisoning, as some parties believe, the outcome could have a similar effect on history, though it risks a much more profound political impact. Finding that line between historical study and modern political intrigue is important for the interesting exercise of retrodiagnosis.

Scientific Misconduct : Government Sanctions Harvard Psychologist

Scientific Misconduct : Government Sanctions Harvard Psychologist | Science, Technology, Medecine and Society | Scoop.it

In 2010, a Harvard University investigation concluded that psychologist Marc Hauser had engaged in scientific misconduct. Last week, the U.S. Department of Health and Human Services Office of Research Integrity confirmed the findings, revealing that Hauser fabricated and falsified methods and data in six federally funded studies. The news brought closure to those who questioned whether Hauser was guilty of any wrongdoing. But because neither investigation indicates which of Hauser's hundreds of publications were investigated, many researchers remain uncertain about how to regard the rest of his work.

Cryonics, avatars or medicine: a transhumanist's dilemma (Wired UK)

Cryonics, avatars or medicine: a transhumanist's dilemma (Wired UK) | Science, Technology, Medecine and Society | Scoop.it

Life-extending technologies are getting more lab time and investment than ever before, and with experts in the field proclaiming the knowledge is just a few decades away, you'll want to be around for it.

 

Over the past decade, the main areas of research -- brain emulation, regenerative medicine and cryonics -- have gradually been departing the realms of science fiction and making a name for themselves in scientific journals. Back in 2009, when Avatar suggested that people could one day upload their brain to an invincible body-double, it seemed like something only James Cameron could dream up. Then a student in Israel controlled a robot with his mind from 2,000km away. In 2009 Aubrey de Grey announced -- to more than a few raised eyebrows -- that the first person to live to 1,000 thanks to regenerative medicine was probably already alive -- and by 2012 a four-year old became the first person to receive a life-saving blood vessel made from her own cells. And around about the same time the horrendous 1997 film Batman & Robin painted cryonics as a field best reserved for psychotic villains, Gregory Fahy and William Rall announced the development of the first cryoprotectant able to vitrify the human body slowly enough that ice crystals don't form and cause tissue damage.

 

Wired.co.uk spoke with leading proponents of each field to find out if we could be convinced to fork out £50,000 to have our brains put on ice. (Wired and Tired by Luke Robert Mason, director of Virtual Futures and advisor to Humanity Plus).

La littérature peut-elle raconter la science ? - France Culture

La littérature peut-elle raconter la science ? - France Culture | Science, Technology, Medecine and Society | Scoop.it

Pour communiquer avec le monde extérieur, les chercheurs disposent d’un unique moyen : la publication scientifique. Lorsqu’ils ont obtenu un résultat, ils le décrivent dans un article extrêmement formaté et le soumettent à une revue spécialisées. Après une relecture par d’autres scientifiques, leur article est publié. Ou recalé. Et la vie continue dans le laboratoire. Des travaux auxquels les scientifiques consacrent leur vie professionnelle, ou plus pour les plus passionnés, le grand public, en général, ne sait rien. Rares, en effet, sont les chercheurs qui troquent la pipette pour la plume afin de raconter leur histoire. Une histoire qui, pourtant, relève souvent de l’aventure. Les articles de vulgarisation qui paraissent dans la presse grand public s’attachent, le plus souvent, aux résultats des recherches. En oubliant les personnages de l’histoire, les acteurs de la recherche qui passent leur vie derrière la porte de leur labo.

 

Et puis, un jour de cette année 2012, quelqu’un d’inhabituel a frappé à cette porte. Il s’agit d’un écrivain, François Bon. Certes, François Bon n’est pas un écrivain comme les autres. Ingénieur de formation, il a travaillé dans l’industrie. Passionné d’informatique depuis ses débuts, il a créé plusieurs sites Internet. Grand amateur de musique rock, il a produit des émissions de radio sur les Rolling Stones, Led Zeppelin ou Bob Dylan… sur France Culture. Professeur, il organise de multiples ateliers d’écritures. Mais, cette année, il s’est embarqué pour un nouveau voyage. De Tours, où il habite, il s’est transporté sur le plateau de Saclay. Et là, grâce à une résidence d’écrivain, il est parti à la rencontre des chercheurs qui peuplent ce lieu peu hospitalier, Larzac francilien battu par le vent, mais promis à un grand avenir.

 

Pour quelles raisons un écrivain s’intéresse-t-il à la vie des scientifiques ?
S’agit-il de recréer des liens entre deux mondes, la science et la littérature, qui ont rompu leurs amarres depuis bien des lustres ?
Qu’a découvert François Bon au cours de ses pérégrinations saclaysiennes ?
Comment les chercheurs, de leur coté, ont reçu cette visite improbable ?
Que peut-il naître d’une telle rencontre, à la fois pour l’écrivain et pour le scientifique ?

Leaving the theatre of the absurd – is open access publishing a necessity for science to flourish?

Leaving the theatre of the absurd – is open access publishing a necessity for science to flourish? | Science, Technology, Medecine and Society | Scoop.it

If this summer’s Royal Society report arguing for a more open practice of science in public policy and business wasn’t convincing enough then the satirical science website PhD (Piled Higher and Deeper) comics, by Panamanian cartoonist Jorge Cham, may change your mind, as it illustrates one researcher’s change of heart when faced with a life and death situation. The film is a digestible eight-minute animation of the problematic scientific publishing landscape and how open access, the free and immediate online availability of research articles with full re-use rights, can add value.

 

The animation was made as part of Open Access Week between 22 and 28 October 2012. Jorge Cham interviewed Nick Shockey, director of student advocacy at the Scholarly Publishing and Academic Resources Coalition (SPARC), and Jonathan Eisen, professor at the University of California Davis, US.

The Internet Through a Postmodern Lens » Cyborgology

The Internet Through a Postmodern Lens » Cyborgology | Science, Technology, Medecine and Society | Scoop.it

Our understanding of the Internet, social networking, and the role of the prosumer in them is greatly enhanced by analyzing them through the lens of a number of ideas associated with postmodern theory.

There is, for example, the argument that the goal in any conversation, including those that characterize science, is not to find the “truth” but simply to keep the conversation going. The Internet is a site of such conversations. It is a world in which there is rarely, if ever, an answer, a conclusion, a finished product, a truth. Instead, there are lots of ongoing conversations and many new ideas and insights. Prime examples of this on the Internet include wikis in general and Wikipedia in particular, blogs and social networking sites. Google’s index is continually evolving and a complete iteration online content is impossible. All such sites involve open-ended processes that admit of no final conclusion.

Postmodernists tend to decenter whatever they analyze and to focus on the periphery. One searches in vain for the center of the Internet or of social networking sites. They are multi-faceted and always in the process of being made. As a result, even if a center could be found (and it can’t), it would immediately change. The idea of the “long tail” reflects this kind of decentering. Instead of focusing on a few “hits”, blockbusters, or best sellers, the long tail involves an emphasis on the infinitely larger number of phenomena (e.g. books, music productions) that are part of the long tail.

Agency, biogenetic discourse and psychiatric disorder

Agency, biogenetic discourse and psychiatric disorder | Science, Technology, Medecine and Society | Scoop.it

In recent years, a growing (and pleasingly interdisciplinary) literature has developed around the intersecting themes of neurogenetic ‘explanatory’ narratives, largely pharmaceutically-driven processes of medicalization, stigma and socioclinical identity in the context of psychiatric disorder.  This post is written by Nev Jones, a psychology doctoral student at DePaul University in Chicago with an extensive background in continental philosophy and enduring interests in the intersections of psychiatry, psychological anthropology, critical neuroscience and cultural theory. His aim is to briefly review two of the most immediate and provocative of these publications, and then launch a more free-ranging reflection on a few key implications.
