According to an article in the journal Advanced Science, researchers at Tel Aviv University were able to create a small 3D-printed heart that included blood vessels out of human tissue.
Until now, researchers have only been able to print simple tissues lacking blood vessels, so a 3D, fully vascularized engineered heart is a step in the right direction.
The process consists of taking a sample of abdominal fat tissue, reprogramming the cells to become induced pluripotent stem cells (iPSCs), differentiating these into cardiac muscle cells and blood vessel cells, and combining them with hydrogels to form structures for the cells to proliferate on.
Heart disease causes one in four deaths in the US (about 610,000 people a year), and there's a shortage of heart donors for transplants, so 3D-printed hearts could help solve a major issue
As a next step, the team plans to culture, print, and transplant similar hearts into animals. Significant challenges still remain, such as the efficient cultivation of the stem cells to gain the large quantity needed to engineer full-size organs and improvement of the blood vessel network demonstrated; the team indicates we are many, many years from from doing this for humans.

Also remember that Nixon widened the scope of the Vietnam war (police action officially) by invading Cambodia without authorization or telling his chiefs of staff (1970).
He also oversaw the Kent State Massacre where American National Guardsmen fired on American College Students on American soil for protesting the war, resulting in 3 dead and 9 wounded (also 1970).
He is remembered by those of us who lived through it for much more than a third-rate burglary. He used the FBI, CIA and IRS against his perceived enemies. He practically wrote the book on abuse of power. Secretly bombed Cambodia long before the invasion while claiming we weren't in Cambodia. There were wiretaps, money laundering, extortion.
And Nixon as well, believed that Executive Privilege protected him from having to release the tapes he made to the Grand Jury.
He was wrong.
Tricky Dick Nixon earned his nickname and scorn.
Trump is an amateur by comparison.
Sorry to run into two posts but you kind of triggered a lot of bad memories of that time period. I lost several relatives to the Vietnam war (one in Cambodia when we weren't there). It was not a good time for America nor my personal life.

I think you missed my point. If I guess correctly I'm about the age you were under Carter or early Reagan. People my age talk about Nixon like he was a cartoon villain not knowing any of the things he did wrong or right. Some of them supported Bush, many supported Obama. Those 2 treated Nixons most evil moments like an SOP. You got Cambodia, I got Iraq, Afghanistan, Syria and Pakistan. Truthfully, I know history well enough to assume the CIA is behind every coup so all of the Arab spring countries as well. Nixons recordings for the NSA revelations from Snowden. Finally Kent state vs how many schools got hit by drone strikes. In return we got none of the party line crossing actual progress. As a country we get the same shit on a bigger scale today in so many ways, yet none of the outrage.

No, I got your point, Nixon wrote the book the following administrations have used as SOP. And it does piss me off that it provokes no outrage at all nowadays.
Historically, I think Nixon will be pointed to as the beginning of the fall.
Thank you for your most interesting description of how later generations view the Nixon presidency. I never thought of it like that despite my love of Futurama. A cartoon. It is a shame we culturally have such a short memory and recall only one crime of a presidency that set the stage for government abuse for the nest forty plus years.
We, at the time hoped the fact that he had self-taped literally tons of evidence that the WH was corrupt, would lead to better oversite. Instead it became the rulebook as Snowden proved many years later.
Hey, didn't mean to come off angry or condescending, Nixon's actions which were so abhorrent when they were discovered, have, like you said, become the standard and is done openly with nary a complaint. It does get me riled up a bit.
Thanks for an interesting perspective on it.
