Artificial protein able to sustain life

Scientists have created a synthetic protein that enables growth of living cells.

A team of Princeton University researchers accomplished the task of creating artificial genetic sequences that are able to sustain life in cells. This groundbreaking achievement shows a great leap forward in the area of synthetic biology. The work shows that the molecular components for life are not limited to what already exists in nature.

One of the goals of synthetic biology, the creation of an entirely artificial genome, may now be within reach, according to Princeton professor Micheal Hecht. Fully functioning artificial components could possibly one day replace faulty or inactive natural proteins that would otherwise cause diseases such as Alzheimer's.

"The team of researchers created genetic sequences never before seen in nature, and the scientists showed that they can produce substances that sustain life in cells almost as readily as proteins produced by nature's own toolkit."

explain to me how it could be possible? You made the claim it would be impossible to create life. I'm asking you to support said claim with evidence. genetic information does'nt just magically appears you need something like a god to bring it into being lol Can you define "genetic information" in your own words?

It probably would be just as healthy for you as artificial vitamins and GMO foods... I was going to say.. that new Quorn looks good as it is based on a mushroom.. but is it??? http://en.wikipedia.org/wiki/Quorn

..Actually the Quorn tastes quite good.. like a lighter version of chicken.. http://keetsa.com/blog/eco-friendly/quorn-mince-for-lasagnas/ I do recall reading a while ago that they were able to grow meat in a petri dish.. and were thinking of adding it to our meat supply like mince.. they also found a way to fuse meat offcuts into whole roasts.. I am beginning to wonder about some of those marinated roasts you can buy in the supermarkets.. they taste quite dodgey... http://news.mongabay.com/2005/0709-rhett_butler.html Experiments for NASA space missions have shown that small amounts of edible ...

Similar research ??? . "We'd like to learn how to make functional proteins that are completely unrelated to natural proteins: that will allow us to continue to build more features." The Penn researchers used three amino acids to make a four-helix columned protein structure. They put a smaller structure inside it called a heme, a large flat molecule that is the active part of hemoglobin. Heme has an iron atom in the center of it, which is what oxygen binds to. The researchers also made the protein structure flexible, so that it can open to receive the oxygen and close again without letting any ... [More]

Similar research ??? ... ??? A foreign protein that would enter the body.. that can hold oxygen.. and what else later ??? ... and not be detected by the immune system so can't be expelled by the body.. ???? A trojan of sorts??? http://www.technologyreview.com/biomedicine/22359/ How are the free online classes going Crystal? If you were doing them, maybe you could provide us with the answers to your questions......
