They were sort of April’s Fool

It is April 1st, fools day, so I decided that whatever new advances I can talk about (and there are quite a few) it would run the risk of being considered an April’s fool. Better then to stick with the past and with things that actually were sort of April’s …

215,000,000,000,000,000 bits in one gram

Bits are really "light"! They are not weightless, as you might think. Depending on the type of media you use to store them each bit has a specific "weight", as an example storing a bit in a flash memory involves some 10,000 electrons and although an electron is really lightweight …

Printing my new home

3D printing is becoming more flexible in terms of materials used to print and size. At the same time its cost keeps going down and these factors fuel applications. 3D printing a house is nothing particularly new. First experiments occurred in the last decade (starting with the printing of foundations, …

Nanoengineering the eye

Technology has made amazing progress towards the creation of the artificial eye. In 2013 ARGUS II, the first  "artificial eye" (a retinal implant converting light into electrical pulses to stimulate retinal neurones disabled by retinitis pigmentosa to send signals to the brain) was approved by FDA as a humanitarian device. …

From WiFi to LiFi

Coding information on a light beam is conceptually the same as coding it on a radio beam. Both are electromagnetic waves the difference being in their frequency, much higher in the case of light (light used to be "seen" as a different branch of physics and those studying it got …

Lightwave computers

Computation through photons, rather than electrons, is not new as an idea but in the past 30 years silicon has proved so effective from a manufacturing point of view and photonics applied to computation so elusive that in practice we only have few photonic chips for very specific applications and …

Stretchable brain interfaces

Scientists are learning to create smart materials with desirable properties like conductivity, flexibility, bio-compatibility and so on. This makes possible their application in areas that were out of touch in the past. A particular challenging area is the one of symbiotic relation between a living being and an articraft. Living …

Touching light

In the next decade I am pretty sure that we will be interacting with objects by touching them, no longer switches and knobs but just surfaces that would look like screens.  We have got used to touch a tablet screen, that is what I am doing right now as I …
