Scientists Create 1st Living Organism From Artificial DNA

WEDNESDAY, May 7, 2014 (HealthDay News) -- Move over, Frankenstein! Your 21st-century counterpart has just been announced.

In true sci-fi fashion, a team of researchers from The Scripps Research Institute (TSRI) in La Jolla, Calif., has created a brand-new bacteria based on a genetic structure found nowhere on Earth.

According to lead researcher Floyd Romesberg, the feat involved artificially engineering a unique combination of DNA material -- a combination not found in any living creature -- and then successfully inserting it into a living cell that usually contains only natural combinations of DNA.

"Life on Earth in all its diversity is encoded by only two pairs of DNA bases, A-T and C-G," Romesberg explained in an institute news release. "And what we've made is an organism that stably contains those two plus a third, unnatural pair of bases."

"This shows that other solutions to storing [genetic] information are possible," he added, "and, of course, takes us closer to an expanded-DNA biology that will have many exciting applications -- from new medicines to new kinds of nanotechnology."

Romesberg and his colleagues discuss their handiwork -- funded in part by the U.S. National Institutes of Health -- in the May 7 online edition of Nature.

The product of more than 15 years of work, the current effort builds on a proof-of-concept study conducted in 2008. At that time, investigators had shown that hooking up natural and unnatural pairings of DNA was possible in a test-tube setting.

The next challenge was to replicate the process inside a living cell. The cell chosen by the TSRI team was the common E. coli bacterium, and into it they inserted what they considered to be the best unnatural DNA pairing they could construct: a combination of two molecules called "d5SICS" and "dNaM".

After leaping through a series of highly complex technical problems, the study authors finally managed to pull off their goal: the fashioning on a half-synthetic organism that could actually replicate its unnatural self as long as scientists continuously supplied it with the necessary molecular material.

Romesberg said that, in principle, his team's high-concept work has a very practical purpose: to gain a "greater power than ever" to fashion new treatments by harnessing the power of genetics.

On May 24th, Earth will for the first time pass through a cloud of dust that comet 209P/LINEAR behind in the 1800's. Experts say it could rival the year's best Perseids shower, with up to 200 meteors per hour.

 

How to get a good internet signal where it is low

This was shared with us by American Kabuki and I think this is such a good Idea worth to share it. Maybe some of you could also use that to improve the signal if you live on a place where it is low and you use a stick to access the net. SiNeh~

How to Get Internet Service in Aouchtam Morocco

 



As many of you know Aouchtam sits in a steep valley and has really poor cell and 3G data reception because there is no local Moroc Telecom cell tower, the nearest ones are near Oued Laou and Amsa which are a few kilometers away. The Internet issue is problem for all the bloggers currently here.

I wish I could take credit for this idea but it was suggested by our resident Russian engineer Levon... I love the way Russian's think!  But I did build it and test it out and it does indeed work well!

Basically its a D-LINK 3G router available at Marjane in Morocco (the Walmart of Morocco), with a Moroc Telecom 3G stick stuck through the LNB hole of a typical satellite dish.  Since cell frequencies are microwave, they are basically the same as satellite signals so the dish makes a very good antenna and concentrates the RF energy to focus on the 3G stick.  I double stick taped the router to the hole, with some super-strength 3M double sided tape I got at Home Depot in the USA (somebody please bring me some  more of that stuff!!!) but you could conceivably use extra strong velcro or silcone sealant to do the same thing.  The 3G stick sits at the focus point of the dish. Viola!  NICE SOLID BLUE SIGNAL!!!! WOOO HOOOO!!!!

D-LINK Corporation, here's your cue for a LNB shaped 3G WIFI router! Go for it! I won't even patent the idea!
 



I have not yet weatherized this, perhaps a plastic bag zip tied around it is sufficient for now to keep the rain and salt air out of the electronics.  I will soon attach it to a pole or perhaps the banister railing for stability.
