Frankentissue: printable cell technology
In November, researchers from the University of Wollongong in Australia announced a new bio-ink that is a step toward really printing living human tissue on an inkjet printer. It is like printing tissue dot-by-dot. A drop of bioink contains 10,000 to 30,000 cells. The focus of much of this research is the eventual production of tailored tissues suitable for surgery, like living Band-Aids, which could be printed on the inkjet.
However, it is still nearly impossible to effectively replicate nature’s ingenious patterns on a home Office accessory. Consider that the liver is a series of globules, the kidney a set of pyramids. Those kinds of structures demand 3D printers that can build them up, layer by layer. At the moment, skin and other flat tissues are most promising for the inkjet.

Italian university switches to English

Milan is crowded with Italian icons, which makes it even more of a cultural earthquake that one of Italy's leading universities — the Politecnico di Milano — is going to switch to the English language. The university has announced that from 2014 most of its degree courses — including all its graduate courses — will be taught and assessed entirely in English rather than Italian.
The waters of globalisation are rising around higher education — and the university believes that if it remains Italian-speaking it risks isolation and will be unable to compete as an international institution. “We strongly believe our classes should be international classes — and the only way to have international classes is to use the English language”, says the university’s rector, Giovanni Azzone.

Ebony and ivory
Ebony and ivory live together in perfect harmony
Side by side on my piano keyboard, oh Lord, why don't we?
We all know that people are the same wherever we go
There is good and bad in ev'ryone,
We learn to live, we learn to give
Each other what we need to survive together alive
