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."

Adorable Dexter and his new chew toy. Thanks Chewy Claus.

True

Every holiday season, millions of kids send letters asking for everything from a new bike to a pony. Some even make altruistic requests such as peace on Earth or helping struggling families around the holidays.

But wouldn’t the holiday season be even more magical if our pets had their wishes granted, too? That’s why Chewy Claus is stepping up to spread holiday cheer to America’s pets.

Does your dog dream of a month’s supply of treats or chew toys? Would your cat love a new tree complete with a stylish condo? How about giving your betta fish some fresh decor that’ll really tie its tank together?

Or do your pets need something more than mere creature comforts such as life-saving surgery?

Teen raises $186,000 to help Walmart worker retire.

In America, many people have to work well past the age of retirement to make ends meet. While some of these people choose to work past retirement age because it keeps them active, some older people, like Nola Carpenter, 81, work out of necessity.

Carpenter has been working at Walmart for 20 years, way beyond most people's retirement age just so that she can afford to continue to pay her mortgage. When 19-year-old Devan Bonagura saw the woman looking tired in the break room of the store, he posted a video to his TikTok of Carpenter with a text overlay that said, "Life shouldn't b this hard..." complete with a sad face emoji.

In the video, Carpenter is sitting at a small table looking down and appearing to be exhausted. The caption of the video reads ":/ I feel bad." Turns out, a lot of other people did too, and encouraged the teen to start a GoFundMe, which has since completed.

Philadelphia is taking the city back to the past.

Remember when calling your parents, a tow truck or a friend when you were out and about meant digging in your pocket for a quarter to make a pay phone call? Well, a Philadelphia-based collective, PhilTel, is jumping into the past with a modern twist, by installing free-to-use pay phones throughout the city.

Of course, the pay phones that many of us grew up were removed from public places years ago. There no longer seemed to be a need for them when most people had a phone in their pocket or in their hand. But it's easy to forget that not everyone has or wants that luxury. For some people, staying that connected all the time can be too much and for others, it's simply financially impossible to own a cell phone.

Think all cats are the same? These pictures prove they each have their own personality

Photographer Nils Jacobi shows how cats aren't nearly as aloof as one might think.

Catographer purrfectly captures cats' purrsonalities.

People often mistakingly attribute a singular personality to cats—usually the words "aloof" or "snobby" are used to describe them. At best, they might be given the "evil genius" label. But in actuality, no two cats are alike. Each has their own distinct ways of being, whether that’s silly, sophisticated, affectionate, downright diabolical or somewhere in between.

This photographer has the pictures to prove it.

Nils Jacobi, better known online as furryfritz, the catographer, has photographed literally thousands upon thousands of cats—from Maine coons who look like they should be in a perfume ad to tabbies in full-on derp mode.
