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!**

Did you know one in five families are unable to provide everyday essentials and food for their children? This summer was also the hungriest on record with one in four children not knowing where their next meal will come from – an increase from one in seven children prior to the pandemic. The effects of COVID-19 continue to be felt around the country and many people struggle to secure basic needs. Unemployment is at an all-time high and an alarming number of families face food insecurity, not only from the increased financial burdens but also because many students and families rely on schools for school meal programs and other daily essentials.

This school year is unlike any other. Frito-Lay knew the critical need to ensure children have enough food and resources to succeed. The company quickly pivoted to expand its partnership with Feed the Children, a leading nonprofit focused on alleviating childhood hunger, to create the "Building the Future Together" program to provide shelf-stable food to supplement more than a quarter-million meals and distribute 500,000 pantry staples, school supplies, snacks, books, hand sanitizer, and personal care items to schools in underserved communities.

Sir David Attenborough has one of the most recognized and beloved voices in the world. The British broadcaster and nature historian has spent most of his 94 years on Earth educating humanity about the wonders of the natural world, inspiring multiple generations to care about the planet we all call home.

And now, Attenborough has made a new name for himself. Not only has he joined the cool kids on Instagram, he's broken the record for reaching a million followers in the shortest period. It only took four hours and 44 minutes, which is less time than it took Jennifer Aniston, who held the title before him at 5 hours and 16 minutes.

A day later, Attenborough is sitting at a whopping 3.4 million followers. And he only has two Instagram posts so far, both of them videos. But just watch his first one and you'll see why he's attracted so many fans.

There are very few people who have had quite as memorable a life as Arnold Schwarzenegger. His adult life has played out in four acts, with each one arguably more consequential than the last.

And now Schwarzenegger wants to play a role in helping America, his adopted home, ensure that our 2020 election is safe, secure and available to everyone willing and able to vote.

Shortly after immigrating to America, Schwarzenegger rose up to become the most famous bodybuilder in history, turning what was largely a sideshow attraction into a legitimate sport. He then pivoted to an acting career, becoming Hollywood's highest paid star in a run that spanned three decades.

One night in 2018, Sheila and Steve Albers took their two youngest sons out to dinner. Their 17-year-old son, John, was in a crabby mood—not an uncommon occurrence for the teen who struggled with mental health issues—so he stayed home.

A half hour later, Sheila's started getting text messages that John wasn't safe. He had posted messages with suicidal ideations on social media and his friends had called the police to check on him. The Albers immediately raced home.

When they got there, they were met with a surreal scene. Their minivan was in the neighbor's yard across the street. John had been shot in the driver's seat six times by a police officer who had arrived to check on him. The officer had fired two shots as the teen slowly backed the van out of the garage, then 11 more after the van spun around backward. But all the officers told the Albers was that John had "passed" and had been shot. They wouldn't find out until the next day who had shot and killed him.
