The power of the sea

An image I've took in Crete during my holidays ... the power of the seaside thrusting toward my camera

Sitia waves

Ended up taking a lot of pictures, as I did last year. They can be found here, but I'm still uploading them!

Nuclear plants in Italy – why not?

Caorso nuclear power plant - ItalySo well, after the recent disaster in Japan, I felt like an urge of putting down some notes on the nuclear choice. In the past, I already wrote (in italian) on Chernobyl disaster and the permanent (i.e. thousands of years worth) damage that occurred in that area, along with the looming threat of a new disaster should the containment structure there fail.

So yeah, while the events are unfolding in the far east, in Italy the debate over building new reactors in my country is still ongoing. The government is is planning to build new, expensive reactors in Italy, and the news from Japan are not putting down the politicians in their intents. Now, if you are not Italian you have to know that my country actually built four reactors in the eighties. Those were shut down after a ballot question following Chernobyl's 1986 nuclear disaster. One of them (Caorso plant) is actually built very close to my hometown (around ~ 20 Km).

Batteri jet

Jet Propelled bacteriaLo sapevate che i primi inventori della propulsione a jet (quella degli aerei, per intenderci) sono batteri? E'questo il risultato raggiunto da uno studio di Andrey Dobrynin della University of Connecticut negli USA. Si è scoperto che alcuni micobatteri (che vivono nel suolo) utilizzano un getto di "slime" per ricavare la forza necessaria a muoversi lungo le superfici. Per lungo tempo si è ritenuto che questo "slime" fosse utilizzato come lubrificante: in realtà si è scoperto che questi microorganismi sono dotati di 250 pori dai quali espellono il materiale "propellente", raggiungendo quindi ragguardevoli velocità pari a 10 micrometri al secondo! I ricercatori sperano che questa scoperta possa fornire nuove idee per la propulsione di agenti nanotecnologici.
