Nanowires Get Into the Groove
ScienceDaily (Aug. 22, 2011) — Growing up is not easy, especially for tiny nanowires: With no support or guidance, nanowires become unruly, making it difficult to harness their full potential as effective semiconductors. Prof. Ernesto Joselevich of the Weizmann Institute’s Chemistry Faculty has found a way to grow semiconductor nanowires out, not up, on a [...]
Lille, quelques dates du 15 au 26 mai 2012 Conte intemporel qui berce en nous un besoin de justice où les bons finissent par être récompensés, Cendrillon a donné lieu à d’innombrables versions aux tonalités très différentes. Entre la mièvrerie acidulée des studios Disney et la cruauté de Perrault ou des frères Grimm, l’adaptation lyrique [...]

ScienceDaily (Aug. 12, 2011) — University of Manchester scientists, working with colleagues in Edinburgh and Australia, have provided the first direct biological evidence for a genetic contribution to people’s intelligence. Previous studies on twins and adopted people suggested that there is a substantial genetic contribution to thinking skills, but this new study — published in [...]

La vidéo que voici est intéressante à plus d’un titre. Tout d’abord, elle remet en comparaison et en relief le mode économique développé par le Japon pour s’être maintenu jusqu’au début des années ’90 aux premières places des puissances économiques mondiales. Mais surtout, il s’agit d’une critique en règle de l’idée d’efficacité d’une réforme qui [...]

L’OTAN n’a pas fini d’entendre parler du cas libyen : présente dans le pays depuis maintenant trois mois, l’alliance atlantique a toujours su intervenir avec parcimonie. Cette parcimonie est désormais remise en question : l’organisation est accusée de bavure par les autorités libyennes du fait d’un raid aérien mené à Tripoli dans la nuit de [...]

June 3, 2011 No Comment
This may have been a domestic dream a half-century ago, when the fields of robotics and artificial intelligence first captured public imagination. However, it quickly became clear that even “simple” human actions are extremely difficult to replicate in robots. Now, MIT computer scientists are tackling the problem with a hierarchical, progressive algorithm that has the [...]
