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.

I will give Nixon credit where credit is due, but no, I respectfully disagree with you, on both Nixon and Trump.
I will say that Nixon made Social Studies classes far more interesting than they would of been without him though. (I was in high school at the time.)
For the record, there were over3000 hours of tapes made, (voice activated) 18 1/2 minutes were 'missing' and his secretary said she was not responsible for the final 13 minutes. They weren't warrentless, the system was installed in 1971 and was not a secret to Nixon as he approved the installation.
The Watergate break-in was simply the culmination of a drunken, paranoid man who was afraid he'd lose an election he won in a landslide. He fucked himself, the tapes also revealed a lot of other inappropriateness within his administration.
Peace out!
