Interesting, but not as new as they'd like you to think (article below from 2004, and the article mentions organ printing first being mentioned in 1999).

Tissue engineering has been the "next big thing" in biotech for a while, and 3D printing-style techniques have been a part of it for some time. It seems that its only recently been picked up by mainstream media.

Yeah, here's a TED talk from 2011 about it: http://www.ted.com/talks/anthony_atala_printing_a_human_kidn...

I remember seeing this talk in person (spoiler alert) and midway through they dragged this up kid on stage who has been living with a bladder built via similar means for 10 years! Closest I've felt to Rip Van Winkle in my life.

I expect we've got a pretty large domestic market here in Scotland for replacement livers.

Even as a Product Designer I tend to sigh when I see articles about 3D printing, especially when they start saying that everything in the future will be printed.

However this is very exciting! This is using 3D printing where it truly will make a difference. I suspect its a good few tens of years off though...

I hate how they redirect to a "better" mobile experience page, and as soon as I see this is happening, I just hit back... How about you? PS. I use iPad mostly to read HN

"Researchers in ..."

I anxiously await for the day when that phrase starts with countries like Bolivia, Mongolia, Sudan, etc. It seems like there are only a few places where world class research is being done. When the rest of the world comes online, hopefully news like this happens daily.

relevant visualization of where research happens: http://www.nature.com/polopoly_fs/7.8087.1355853889!/image/c...

I'm really curious about all the research coming out of Iran. would not have expected a country under lockdown to be doing so much research.

..."and as president, I promise to up our research unit output by a factor of 50%. I assure you my opponent does not have a comparable strategy for increasing research unit output - nor any other factors, such as his misguided job-unit creation plan."

I'd like to see the same visualization, but for the distribution of the nationalities/origin of the actual paper authors.

i.e. of the ~300K papers published in the US, how many of those papers were authored and co-authored by immigrants (H1-B, or naturalized) etc.

I suspect that a greater % of these papers were written by foreign born researchers.

I would expect the general trends to be about the same, though all less pronounced.

Say 25% of the researchers in the US were born in the US: The US column would drop significantly but since that other 75% is probably spread more or less evenly across the other columns, they would only all rise a little.

The only really dramatic change I would expect would be to mainland China. It probably wouldn't loose much, but would likely gain quite a lot.

Confused: I read that title as creating cells. Instead they are printing using cells as the ink.

Just by printing a full human heart we'd be able to work until age 80 without feeling tired all day ..?
