Data have been considered (along with Turing idea of computation) as input or output. They are outside of the network. Well, my idea is that once you have a loto of interconnected data they are not just becoming part of the infrastructure, they actually are the infrastructure.  In tomorrows’ cities …

I have posted few months ago some considerations on the relationship existing between the pro-capita wealth of a city and its dimension. On the average we can see a strong resemblance to the relation existing between the methabolic rate of an animal and its size (the Kleiber law). Whereas in …

I know that I am going against the flow, and declaration of many, but I feel that we will never have a Smart City. Smart is not a destination, at least in my view. It is a long, and winding, road that has to be followed. As new needs surface (population …

Shangri-La was the ideal place. People lived in harmony a long life a perfect Smart City (and valley). Unfortunately, Shangri-La it is a figment of the imagination (of James Hilton). Cities have never managed to be "smart" enough. This is not surprising. A city is a "living" system in a …

I am in Paris giving an opening talk on Smart Cities, the EIT ICT Labs organisers having asked me to take a broader view on the subject. And here I am sharing it with you. The title of the talk is "How will be our cities be remembered a thousand …

Graphene, a one one carbon atom thick layer, is completely impermeable to atoms, including the smallest ones, like hydrogen atoms. This is now being exploited to create a perfect anti-corrosion surface (since no acid, nor oxygen could reach atoms placed under a graphene cover). Now, researchers at the university of Manchester, …

Oxygenated blood absorbs infrared light proportionally to the amount of oxygen carried by red blood cells. On the contrary red light is absorbed most by not oxygenated blood, or at an inverse proportion of the presence of oxygen on red blood cells.  By calculating the ratio of infrared vs red …

It is now a few years that drugs dispensers can be implanted under the skin to release substances gradually. More recently electronic dispensers have been implanted. They contain a microprocessor and can sense their environment to detect a need for releasing a certain amount of medicine, like insulin. Most are …

Several progresses have been made since the turn of the century in embedding electronics in flexible materials thus making it possibile to embed sensors in many types of surfaces. At the Seoul National University, SNU, a team of researchers have created an artificial skin with embedded sensors that can be used to provide a …

HP invented the memristors (some would even say "discovered") several years ago and managed to create memristors on a dye after that so that memristors chips could be produced. Now they have announced the release in 2015 of an Operating Systems that will allow developers to create applications based on memristors, making …
