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.

Instagram recently faced backlash for swapping its iconic square grid for rectangles, disrupting the aesthetic of thousands of carefully curated profiles. However, the Meta-owned platform isn’t stopping there, after announcing more incoming TikTok-like changes designed to give users greater control over their profiles.

“We launched a new tall grid on profiles this week and I got a lot of feedback, both positive and quite negative,” Instagram head Adam Mosseri shared in an Instagram caption on Monday. “The goal is a simpler, cleaner place that maintains, and even increases, creator control”.

Here are some of the details about further changes we can expect:

Customizable Grids: Users will soon be able to tweak how their posts appear on the grid, including adjusting image crops and reordering posts entirely.
Direct-To-Grid Posts: A new option will allow users to post directly to their profile grid without automatically adding it to their main feed.
Highlights Relocation: Instagram’s Highlights feature will move from above the grid into a dedicated tab, while also becoming part of the profile grid itself.
Longer Reels: Reels are getting a significant upgrade, with the maximum video length jumping from 90 seconds to 3 minutes.

The updates are part of Instagram’s ongoing effort to compete with TikTok, which narrowly avoided a US ban following a 75-day delay granted by President Donald Trump. With the Chinese video platform’s future remaining uncertain, Instagram seems eager to capture disillusioned users by offering features that feel increasingly similar to those of its rival.

In fact, Instagram’s recent changes go beyond just the app’s layout: On Sunday, parent company Meta launched the standalone Edits app, a clear imitation of TikTok’s popular video-editing tool, CapCut. Additionally, Meta has been enticing creators with cash bonuses to encourage them to post their videos on Instagram and Facebook.

It’s clear Instagram is shifting its strategy to appeal to the short-form video crowd. Whether these changes will win over users or continue to spark discontent remains to be seen.
