| Cytat: | So, tissue design. In this case too, you have a mixture of scientists and designers. This here is part of the same lab at the Royal College of Arts. The RCA is really quite an amazing school from that viewpoint. One of the assignments for a year was to work with in-vitro meat. You know that already you can grow meat in vitro. In Australia they did it -- this research company, called SymbioticA, But the problem is that it's a really ugly patty. And so, the assignments to the students was, how should the steak of tomorrow be? When you don't have to kill cows and it can have any shape, what should it be like? So this particular student, James King, went around the beautiful English countryside, picked the best, best cow that he could see, and then put her in the MRI machine. And then took the scans of the best organs and made the meat. Of course, this is done with a Japanese resin food makers, but you know, in the future it could be made better. But that reproduces the best MRI scan of the best cow he could find.
And instead, this element here is much more banal. Something that you know can be done already is to grow bone tissue so that you can make a wedding ring out of the bone tissue of your loved one -- literally. So, this is indeed made of human bone tissue.
This is SymbioticA and you, know, they've been working, they were the first ones to do this in-vitro meat, and now they've also done an in-vitro coat, a leather coat. It's miniscule, but it's a real coat. It's shaped like one. So, we'll be able to really not have any excuse to be wearing everything leather in the future. |

Wczoraj na kanale Palnete:
Witamy w nanoświecie
ogladałam od jakiegoś momentu
To już nie fikcja, naprawdę. GMO i nanożywność, ubrania, pralki, lodówki
super.
tu jest link:

o nano świecie nie tylko w TV

sprzed 10 lat tekst a jednak się sprawdza
mamy rok 2010

o toksyczności wersji nano

choć tlumaczenie trochę szwankuje im bardziej naukowy tekst w google

a tutaj o podobno dobrym wpływie srebra wmedycynie o czym też było w filmie ale srebro jest toksyczne dla człowieka i nie wiadomo jaka ilość jest ok
http://www.spacedaily.com/news/nanotech-05zzx.html
Aha jednym z problemów o jakim było w filmie, że tak naprawdę trudno wszystko zbadać bo jest w wersji nano i,że jak ktoś stwierdzi, że taka powłoka ze srebra wytryzmuje iles dni, lat a potem sobie coś wyrzucimy na śmietnik? Albo kto to zutylizuje, jak nagromedzenie wielu nanoczastek wpłynie na środowisko, tego nie wie nikt.

Imagine a cancer drug that can burrow into a tumor, seal the exits and detonate a lethal dose of anti-cancer toxins, all while leaving healthy cells unscathed. Wyobraź sobie lek na raka, które mogą nory do guza, uszczelnienia wyjścia i zdetonować śmiertelną dawkę anty-nowotworowych toksyn, wszystkich, pozostawiając zdrowe komórki bez szwanku.

Temat postu: Nanoparticles loaded with bee venom kill HIV
http://news.wustl.edu/news/Pages/25061.aspx
| Cytat: | Bee venom contains a potent toxin called melittin that can poke holes in the protective envelope that surrounds HIV, and other viruses. Large amounts of free melittin can cause a lot of damage. Indeed, in addition to anti-viral therapy, the paper’s senior author, Samuel A. Wickline, MD, the J. Russell Hornsby Professor of Biomedical Sciences, has shown melittin-loaded nanoparticles to be effective in killing tumor cells.
The new study shows that melittin loaded onto these nanoparticles does not harm normal cells. That’s because Hood added protective bumpers to the nanoparticle surface. When the nanoparticles come into contact with normal cells, which are much larger in size, the particles simply bounce off. |
