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.
ā[This is] the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,ā Dr. Tal Dvir, who led the project, told the press.
āPeople 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."
**Pun proudly intended.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
āBut the REAL question is: do you now have X-Ray vision?ā
āYou can just say you're a superhero.ā
āI would make a few stops on the way home just to freak some people out!ā
āI would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.ā
āThis one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.ā
āI would save those for fancy special occasions! WOW!ā
āEvery time I'd stop I'd turn slowly and stare at the person in the car next to me.ā
āKeep them. Tell people what to do. Theyāll do your bidding.ā
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
