Thanks to the work of a group of Israeli scientists, we’re one step closer to being able to grow human babies in artificial wombs. The scientists, led by Professor Jacob Hanna, have successfully extracted 250 embryos from pregnant mice and placed them in a contraption designed to simulate the uterine wall and give the embryos the right conditions to grow.

“We have grown hundreds of mice in this way, in a method that has taken seven years to develop, and I’m still captivated every time I see it,” said Hanna, who works at the Weizmann Institute of Science, a public research university in Rehovot, Israel. “This could be relevant to other mammals, including humans, though we acknowledge that there are ethical issues related to growing humans outside the body.”

Hanna and his team have revealed their breakthrough in the peer-reviewed journal Nature, a multidisciplinary publication known for publishing the finest research from a variety of academic disciplines.

Previous experiments of this kind involved fetuses with already developed organs, such as when the Children’s Hospital of Philadelphia grew fetal lambs for over four weeks in artificial wombs back in 2017. The Israel-based team started with five-days old embryos consisting of just 250 cells, placing them into a special liquid to provide nourishment.

“By day 11, they make their own blood and have a beating heart, a fully developed brain. Anybody would look at them and say, ‘this is clearly a mouse fetus with all the characteristics of a mouse.’ It’s gone from being a ball of cells to being an advanced fetus,” explained Hanna.

While this experiment certainly invokes unsettling scenes from the movie Matrix, with machines growing humans in massive quantities to extract electricity from their bodies, scientists are still a long way from applying the research to create life outside the human body. It’s even possible that the ethical issues surrounding such research will lead to its bad, or at least a heavy regulation.

Spotify Is Experimenting With Artist NFT Collections

According to a recent survey, it seems that the currently tested NFT collections are just the first step toward a much broader implementation of NFTs into the platform.

NFT sales may have declined by 92 percent since September 2021, but that’s not stopping Spotify from experimenting with a new feature that lets artists display their non-fungible token (NFT) collections on the music streaming platform.

At the moment, only a small group of artists are taking part in the experiment, including Steve Aoki and The Wombats. What’s more, only select US users of the Spotify app for Android can see NFTs when they visit the profile pages of the aforementioned artists.

“Spotify is running a test in which it will help a small group of artists promote their existing third-party NFT offerings via their artist profiles,” said Spotify spokesperson. “We routinely conduct a number of tests in an effort to improve artist and fan experiences.”

It’s important to point out that not all Spotify experiments result in new features. It all depends on the feedback the music streaming platform receives from users.

According to a survey some Spotify users have recently received, it seems that the currently tested NFT collections are just the first step toward a much broader implementation of NFTs into the platform. More specifically, Spotify seems to be thinking about allowing its users to directly purchase NFT art to support their favorite artists.

Considering how polarizing NFTs have been since their inception in 2014, it shouldn’t come as a surprise that many Spotify users have immediately expressed their dissatisfaction with the idea of NFTs becoming part of the Spotify music listening experience.

Other large tech companies are also experimenting with NFTs. Instagram, for example, started testing NFT integration last week, allowing NFT creators and collectors to display their tokens on the platform. Mark Zuckerberg himself believes that NFTs and digital collectibles in general will play an integral role in the metaverse, the new iteration of the internet.
