Un bug déconnecte des missiles nucléaires américains pendant une heure

D'après le Los Angeles Times, les responsables militaires ont insisté sur le fait que les missiles n'auraient absolument pas pu être lancés de manière accidentelle, et ajouté que si les Etats-Unis avaient eu besoin de lancer des missiles dans l'escadron affecté par le bug, ils auraient pu utiliser des systèmes de secours.

L'incident n'a été relaté que ce mardi, parce que les responsables voulaient pouvoir examiner le système de lancement des missiles avant d'en discuter. Quand il est apparu qu'il s'agissait d'un souci technique, et non pas d'une attaque d'un autre pays par exemple, l'inquiétude de l'armée a été levée et les responsables ont communiqué.

Parental nurturing important for normal functioning of brain later in life – epigenomic impact | rndsync's Blog: "Just as in complex systems small perturbations at the beginning have huge impact on the outcome later, scientists in these researchers found that small changes in maternal care had long lasting changes even into adulthood.
'We already knew that maternal care determined the stress responses of an offspring through a similar process, but this is the first time maternal care has been shown to link, via epigenetics, with a key enzyme that causes a major human disorder,' said Jonathan Seckl, MD, PhD, of The University of Edinburgh, and an expert on the molecular process of hormones."

Cyberterrorism: mysterious computer virus attacks Iran - Miami Technology | Examiner.com: "Cybercasters in South Florida and around the world got chilling news of a cyber warfare going on. The diplomatic tensions related to the development of civilian nuclear power in Iran moved to new dimensions:cybernetics.

The Man Who First Said 'Cyborg,' 50 Years Later - Alexis Madrigal - Technology - The Atlantic: "We're gathered here today to celebrate Manfred Clynes. Fifty years ago, he coined the word 'cyborg' to describe an emerging hybrid of man's machines and man himself. The word itself combined cybernetics, the then-emerging discipline of feedback and control, and organism."
