“Recent studies have shown that stigmergy is not necessary to explain concerted construction: Green et al. showed that worker aggregation rather than the previously suspected presence of cementation pheromone localized excavation work sites in termites, and Bruce found no behavioural response to freshly excavated soil that would contain a digging pheromone were it an organizing factor in excavation in leafcutter ants. Eciton army ants, which self-assemble into bridges to cross trail gaps, gauge the necessity to reinforce or leave these structures based purely on the rate of physical contact with passing workers with no evidence of stigmergic processes.”

«L’American Psychological Association a récemment résumé les précédentes découvertes sur les jeux vidéo violents en indiquant qu’ils présentaient un risque en termes de rapport à autrui, notamment d’agressivité accrue et de diminution de l’empathie. Cette étude contredit clairement cette conclusion».

«Les prétentions à la suzeraineté de ces plates-formes, pour reprendre la formule de Alain Supiot (2) dans Gouverner par les nombres, doit être combattue par la souveraineté des États (comme le fait le RGPD) pour contraindre ces plates-formes à remettre dans le domaine public toutes les données et traces qui sont à leur disposition, données produites par le public et qui méritent d’être reprises, traitées et contrôlées par des organismes scientifiques publics avant d’être mises à disposition des chercheurs dans des conditions précises comme c’est le cas pour les recensements (et donc avec des limites). Les principes de la science ouverte risquent fort de rester des vœux pieux si on ne s’attaque pas dès maintenant à cette prédation des données par l’oligopole de l’attention que constituent les GAFAMT» – Dominique Boullier.

«The most basic problem is that researchers often don’t share their source code. At the AAAI meeting, Odd Erik Gundersen, a computer scientist at the Norwegian University of Science and Technology in Trondheim, reported the results of a survey of 400 algorithms presented in papers at two top AI conferences in the past few years. He found that only 6% of the presenters shared the algorithm’s code. Only a third shared the data they tested their algorithms on, and just half shared « pseudocode »—a limited summary of an algorithm. (In many cases, code is also absent from AI papers published in journals, including Science and Nature.)».

«The Trump administration has stepped up its assault on environmental protections by halting a US$1-million study on the health risks of coal mining — casting a pall on academic freedom».

« October 30th, 2010 marks the day that my sister Amy and I founded Meta on a mission to unlock scientific knowledge and accelerate the pace of discovery. In six years, through the hands and minds of our talented team of engineers and scientists, we figured out how to use artificial intelligence to analyze new scientific knowledge as it’s published – along with the majority of what has been written, throughout modern history. Those efforts have led us to today.I am excited to announce that Meta will be joining the Chan Zuckerberg Initiative to bring what we have built to the entire scientific community, toward their goal to cure, prevent, or manage all diseases by the end of the century ».

Alarmed that decades of crucial climate measurements could vanish under a hostile Trump administration, scientists have begun a feverish attempt to copy reams of government data onto independent servers in hopes of safeguarding it from any political interference.
« Bref, on est dans une situation assez incroyable où des données obsolètes produisent des résultats qui ne correspondent pas à la réalité. Mais ce sont ces résultats qui servent aux décideurs politiques à définir leur politique énergétique pour les décennies à venir ».
When a study of 42 subjects inspires 34 million people, it’s not unreasonable to go back and check the results.
The internet has become embedded into our daily lives, no longer an esoteric phenomenon, but instead an unremarkable way of carrying out our interactions with one another. Online and offline are interwoven in everyday experience. Using the internet has become accepted as a way of being present in the world, rather than a means of accessing some discrete virtual domain. Ethnographers of these contemporary Internet-infused societies consequently find themselves facing serious methodological dilemmas: where should they go, what should they do there and how can they acquire robust knowledge about what people do in, through and with the internet?
