scientists at UCLA have used a powerful microscope to image the three-dimensional positions of individual atoms to a precision of 19 trillionths of a meter, which is several times smaller than a hydrogen atom.
Their observations make it possible, for the first time, to infer the macroscopic properties of materials based on their structural arrangements of atoms, which will guide how scientists and engineers build aircraft components, for example. The research, led by Jianwei (John) Miao, a UCLA professor of physics and astronomy and a member of UCLA's California NanoSystems Institute, is published Sept. 21 in the online edition of the journal Nature Materials.
One step closer to The Diamond Age.

That's a good journalist. That's rare and they should be complimented for not screwing up, as 90% of their profession makes the decent 10% of them look overly bad. Did not have to read the source paper to learn the key points were ultra super high res rather than historical blurry STM images we all saw decades ago, and they had an interesting angular scan platform strategy to get 3d data,and they were excited to find and map out a point defect in great detail.
Unfortunately the site business model is spam, and I get a big rectangle at the top nagging me to shut off my ad blocker. LOL that ain't happening and ad blocking directly correlates with intelligence so a science news site based on a spam business model is pretty much doomed. The mobile app has comments about the app being ruined by shitty loud video ads, so no mobile for them. Too bad, nice site, sad its going away. I'd drop them some money for a spamless experience but its not even an option. Oh well, was nice seeing it, while its still here.
Point defects are cool. "We" all sat thru the basic solid state semiconductor lessons a long time ago about a rather idealized model of silicon physics where the occasional point of a rare contaminant either injects an excess electron or is short one electron and you can exploit the hell out of combinations of that to make transistors. Point defects can do other cool things, too.

The site won't display even any text without Javascript. Had to add it to NoScript whitelist just to be able to read the article.

I do a staged unblock if a site comes up blank (on the content). after a few tries - if there is still nothing - I leave and don't come back.
this crap ruined the web. you mean you have to RUN CODE in my browser for me to see TEXT? fuck you, webmaster. just go fuck yourself.
pisses me off.
the way I handle this is that most of the news stories I would want to read also appear in aggregators (such as fark). if I can't see the article, I can see the fark comments and they often are even more 'telling' about the subject matter, also often including graphics that the article tried to 'protect'. I'm more after the commentary, anyway, as it helps complete the story and balances the 'corp speak' that is all we hear from jscript-locked content.

wait -- you're saying they are following in the long line of responding to articles without having first read them, and that you believe they are more telling than the subject matter and article itself?
Where do you think you are... Slashdot?
Maybe we need to embrace the methods of the past in order to deal with the future! No one read the article then because bandwidth was too low, but no one can actually read them now due to technological advancement.

Complete agreement (I do the same as you with NoScript), and since I didn't even have to try that I found other sources (below) and the actual paper [ucla.edu] as published (it's only 8 pages total including all the references and nitty gritty, so more like 4 but plenty enough to make my brain hurt) among the publications at the page of the UCLA Coherent Imaging Group [ucla.edu] who wrote it.
There's also a phys.org writeup [phys.org] and an ecnmag writeup [ecnmag.com]. These two are very similar to each other but not identical.
None of the above links require scripts so please enjoy :)

Gah I forgot to point out that the actual paper is a PDF but I guess most would assume that, still I prefer adding a warning/note to PDF links but it slipped —sorry :|

I don't turn javascript off but with FF + Ad blocker + Ghostery I'm not seeing what you're seeing.
Didn't realize the link was so annoying--sorry about that.

It was reported on a couple of days ago at:

If I unblocked it, it was long enough ago that I don't remember doing so, so I think it works with JavaScript disabled.
Javascript is what you use to allow unknown third parties to run software you have no idea about on your computer.

Sorry, I have to say something here. The STM did a hell lot of development since the 'history' you are referring to. Not to speak about the atomic force microscopy in the dynamic mode, which has now even better resolution.

How is completely failing to mention other labs doing this in 25 years ago good journalism?

IBM scientists discovered how to move and position individual atoms on a metal surface using a scanning tunneling microscope. The technique was demonstrated in April 1990 at IBM's Almaden Research Center in San Jose, Calif., where scientists created the world's first structure: the letters "I-B-M" -- assembled one atom at a time.
