Muitas e boas Notícias!

A Samsung adopta uma Tecnologia desenvolvida em Portugal!
Do Site chamado Boas Notícias:

Poderá ser o fim do velho silicío na construção dos ecrãs televisivos. Investigadores da Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa desenvolveram, em colaboração com a Samsung, uma nova geração de ecrãs que recorre a um novo novo tipo de transistores transparentes e mais baratos.

A novidade consiste na substituição do material semicondutor dos transístores, que é neste momento silício, por um novo material transparente à base de óxidos, como o óxido de zinco, e que oferece várias vantagens.

Este material - que tem já muitas aplicações como por exemplo nos cremes cicatrizantes e nos protetores solares - pode ser produzido a um custo muito mais baixo e à temperatura ambiente, disse esta semana à agência Lusa Elvira Fortunato, que coordena o projeto juntamente com o seu colega Rodrigo Martins.

Como construír um Dinossauro, a partir duma Galinha!

Video: How to Build a Dinosaur from a Chicken
By Clay Dillow

How does one build a dinosaur? There’s the much-celebrated Crichton/Spielberg method, in which you extract dino DNA from a preserved prehistoric mosquito. But there are problems with this approach, says paleontologist Jack Horner in a recent TED Talk, and besides: there are plenty of spare dinosaur parts laying around our modern world from which to build a dinosaur. We just need to find the right ones.

Horner has spent a career digging up some of the best-preserved biological artifacts leftover from the dinosaurs’ tenure on this planet, but in none of them, not even the soft tissues like preserved blood vessels, could he or his team find intact DNA--the kind you need to clone a dinosaur a la Jurassic Park. So he and some colleagues are looking for dino-era DNA in dinosaurs’ descendants: modern birds.

Video: Airbus Offers a Peek at the Translucent Future of Passenger Air Travel
By Clay Dillow
Airbus has seen the future, and it's spacious, sunlit and full of interactive screens. Oh, and cocktails will be served in the virtual bar, assuming someone isn’t playing 18 holes in there.

After revealing its larger vision of what aviation hardware will offer us in 2050 at last year’s Paris Air Show--reduced emissions, lower fuel consumption, reductions in noise and increases in speed--the company has turned its attention toward the passenger experience, offering a sneak peak of the future via the video below.

What does the future have in store? Well, assuming populations begin growing less obese and the economics of packing as many people on a flight as possible are discarded (in the future, air travel--like society--will know no class), the future is much more comfortable.
When flights are at less than full capacity, unneeded seats at the rear of the plane will collapse and all seats will redistribute themselves to offer everyone an equitable boost in legroom. These seats will also morph to fit passengers’ bodies.
