A research team in Israel made a 3D-printed heart from human tissue and vessels.

Have you ever stopped and thought, "How awesome would it be if I could live forever?"

The answer to that question is probably a hearty "yes," because most of us are both afraid of death and haven't yet watched enough "Twilight Zone" to recognize that immortality is kind of a scam.* Well, good news, seekers of everlasting life: A research team in Israel has created a 3D-printed heart that's actually made of human tissue and vessels.

Of course, this doesn't mean you living forever is a lock, yet. This heart is just a prototype at the beginning stages of its journey, but the implications of this research are incredible. While this heart is only fit for rabbit-sized animal, further experimentation may soon lead to larger hearts that could be used for human transplants. Patches that regenerate defective heart tissue, The Times of Israel notes, are also on the table.


“[This is] the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” Dr. Tal Dvir, who led the project, told the press.

“People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels."

The team's next challenge is to teach the heart to behave correctly (which seems like the setup to a rom/com if you ask me). Currently, the model heart can contract, but it cannot yet pump blood. After that's figured out, researchers can implant the hearts into animal models to see how they'll respond.

Optimistically, scientists hope that functioning human organs will be able to be printed in hospitals within the next ten years. Although Dvir believes that medical facilities will start with the "simpler organs" first.

One of the coolest things about the new breakthrough? The 3D-printed hearts can use a person's own tissue to create the artificial organ. So once this is a viable option, it'll also reduce the risk of bodies rejecting the organ.

Heart disease is the number one cause of death in the world. Could a 3D-printed heart change all that? We're be(a)tting on it!**

*Or have watched enough Twilight Zone to recognize that immortality is a scam and still think "I could do it better."

Last year, we shared the sad impact that plastic pollution has had on some of our planet's most beautiful places. With recycling not turning out to be the savior it was made out to be, solutions to our growing plastic problem can seem distant and complex.

We have seen some glimmers of hope from both human innovation and nature itself, however. In 2016, a bacteria that evolved with the ability to break down plastic was discovered in a Japanese waste site. Two years later, scientists managed to engineer the mutant plastic-eating enzyme they called PETase—named for polyethylene terephthalate, the most common plastic found in bottles and food packaging—in a lab.

Here's an explainer of how those enzymes work:

Now researchers have revealed another game-changer in the plastic-eater—a super-enzyme that can break down plastic six times faster than PETase alone.

Former CBS News anchor Dan Rather has become a beloved voice of reason, knowledge, and experience for many Americans on social media the past few years. At 88, Rather has seen more than most of us, and as a journalist, he's had a front row seat as modern history has played out. He combines that lifetime of experience and perspective with an eloquence that hearkens to a time when eloquence mattered, he called us to our common American ideals with his book "What Unites Us," and he comforts many of is with his repeated message to stay "steady" through the turmoil the U.S. has been experiencing.

All of that is to say, when Dan Rather sounds the alarm, you know we've reached a critical historical moment.

Yesterday, President Trump again refused to commit to a peaceful transfer of power after the election when directly asked if he would—yet another democratic norm being toppled. Afterward, Rather posted the following words of wisdom—and warning—to his nearly three million Facebook fans:

On February 26, 2019, Stacy and Babajide Omirin of Lagos, Nigeria got quite the shock. When Stacy delivered identical twins through C-section one came out black and the other, white.

The parents knew they were having identical twins and expected them to look exactly the same. But one has a white-looking complexion and golden, wavy hair.

"It was a massive surprise," Stacy told The Daily Mail. "Daniel came first, and then the nurse said the second baby has golden hair. I thought how can this be possible. I looked down and saw David, he was completely white."
