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.

samsung galaxy ring wearable will launch in eight sizes

The global launch of the Samsung Galaxy Ring is hotly anticipated, with details about the next-gen wearable gradually emerging since the company’s teaser announcement back in January. Now, a report has also unveiled the model numbers for the device, suggesting it will be available in eight different sizes.

While Samsung has yet to divulge detailed specs and features of the Galaxy Ring, it’s likely to feature an array of health and sleep monitoring functionalities, while boasting a battery life of up to nine days on a single charge.

As per a Galaxy Club report, there are currently eight confirmed variants of the Galaxy Ring: SM-Q500, SM-Q501, SM-Q502, SM-Q505, SM-Q506, SM-Q507, SM-Q508, and SM-Q509.

However, the mystery shrouding two absent model numbers persists, leaving speculation as to whether they signify additional sizes or if Samsung plans to unveil a later ninth variant of the ring, as previously hinted. There’s conjecture that these models may correspond to US ring sizes 5 and above, commencing with the SMQ500, with subsequent numbers potentially indicating larger ring sizes, possibly reaching up to size 13, aligning with model number SM-Q509.

Recent Korean reports have shed light on how Samsung’s Mobile eXperience division (MX) collaborated with the Home Appliance department to integrate Samsung Food with the Galaxy Ring: Tailored for daily activity tracking, the Galaxy Ring, when paired with Samsung Food and an intelligent Samsung refrigerator featuring AI vision, delivers personalized dietary guidance based on calorie intake and BMI.

Samsung is banking on the user-friendly interface and high durability of the ring to redefine the healthcare wearables landscape. Meanwhile, Apple is also making strides in the development of a smart ring, aimed at monitoring users’ health biometrics discreetly when worn on the finger. According to the Electronic Times report, Apple has been closely monitoring market interest in this more inconspicuous alternative to a traditional watch.
