Breakthrough

Video shows a living heart being printed out, with clear veins.

Until now, scientists have only been able to print basic tissues, without cells or blood vessels.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles, and chambers,” said Professor Tal Dvir, lead researcher on the study.

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

Obviously, it’s a small heart, about the size of a rabbit’s. But the researchers said the technology needed to print a human heart is the same.

Cardiovascular disease

In accordance with WHO, cardiovascular diseases take the lives of 17.9 million people every year, 31% of all global deaths.

Triggering these diseases -which manifest primarily as heart attacks and strokes -are tobacco use, unhealthy diet, physical inactivity and the harmful use of alcohol.

In England, cardiovascular disease accounts for 26% of all deaths, and many people wait for heart surgery. The breakthrough could reduce waiting times for surgery and save millions of lives around the world as patients no longer have to wait for a heart donor.

What’s more, compared with traditional organ transplants, the 3D-printed cells minimize the risk of rejection and complications because it comes from the patients themselves.

Hope

While it looks like a heart, structurally, it’s not yet functional and doesn’t pump. It is worth noting that this technology is still very far from being able to replace heart transplants.

The crucial next task, as Prof. Dvir says, is to teach them to behave like hearts; he explains that they “need to develop the printed heart further. The cells need to form a pumping ability; they can currently contract, but we need them to work together.”

There is still a long road ahead, but the researchers are excited about how far they have come.

According to the nutritionist, not many Chinese restaurants in New York care about the quality of ingredients compared to her restaurant.

“There are very few American-Chinese places as mindful about the quality of ingredients as we are,” she said. “We’re excited to offer it to people who want this type of food, and it can make them feel good and they can workout after and they can feel focused after and it will add to their health.”

On one Instagram post, the restaurant said unlike other places, it offered lo mein that did not make their customers feel “icky”.

“We heard you’re obsessed with lo mein but rarely eat it,” the now-deleted post read. “You said it makes you feel bloated and icky the next day? Well, wait until you slurp up our HIGH lo mein. Not too oily. Or salty.”

For Haspel, by opening a Chinese restaurant, she hopes to celebrate Asian culture.

“I love love love American Chinese food. I made some tweaks so I would be able to eat it and my friends and other people would be able to eat it,” she said. “I am by all means never ever looking to put down culture at all. I am very inclusive, and we’re here to celebrate the culture.”

Her restaurant will feature “a lot of Chinese elements” such as “lucky bamboo” and “jade”.

However, social media users were having none of it.

“This white woman just opened a ‘clean’ Chinese food restaurant … not only is she using Chinese food stereotypes/naming, she is shaming traditional Chinese food cooking with MSG/grease/starch,” one commenter said.

“This restaurant uses racist tropes to position itself as better than a traditionally Chinese-owned restaurant for no good reason,” said one person.

Thanks, all of you! 

The activity has attracted many HACOS supporters, which is amazingly out of our expectation.
