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.

Apple’s latest updates to its popular iPad Air and Pro models were announced on Tuesday, May 7. These are the first changes since 2022, the longest stretch between new models since the iconic device was revealed in 2011.

Both the 11-inch and 12.9-inch versions of the iPad Pro have received a huge design overhaul. The most noteworthy change is the move to OLED screens, with the 12.9-inch version receiving a small bump in size to 13 inches. Apple claims the new tablets are brighter and more vibrant than outgoing models, thanks to a technology it calls “tandem OLED” or “Ultra Retina XDR”.

The 13-inch model now measures an astonishing 5.1 mm in thickness, which Apple says is its slimmest device ever. (The 11-inch version is 5.3 mm thick.) For those who prefer the look of a matte display, a nano-texture coating will also be available for the first time on the Pro models.

Finally, the new iPad Pros have received a processor bump to the latest M4 chip, which Apple says is an “outrageously powerful chip for AI”, offering an example of its ability to quickly and efficiently isolate subjects from backgrounds in videos.

The iPad Pro 11-inch starts at $999, and the larger 13-inch version starts at $1,299 with 256GB of storage.

Updated iPad Air In Two Sizes

The sixth-generation iPad Air didn’t receive as many upgrades as the iPad Pro but significantly does now come in two sizes. As with the Pro models, buyers now have the choice between an 11-inch and 13-inch screen, meaning they don’t need to invest in a Pro version just to get a 30% bump in display size.

Apple kept the same design for the iPad Air that it first revealed in 2020, complete with a USB-C port and Touch ID in the top button. The only difference is the front camera placement, which has been moved to the center of the iPad when in landscape orientation.

The 11-inch iPad Air is priced at $599 for the entry-level model, while the 13-inch version starts at $799.

New Magic Keyboard Case

Apple also announced an updated (thinner, lighter) Magic Keyboard for its Pro iPads. The refreshed version now includes a function row (with controls for screen brightness). An aluminum palm rest and large trackpad with haptic feedback also help the premium case feel more like a Macbook.

The new Magic Keyboard is available for both the 11-inch and 13-inch iPad Pros and will be priced at $299 or $349, respectively.

Apple Pencil Pro

Apple also announced a new Apple Pencil, named Pro, at its event. The new model looks exactly the same but adds a “squeeze” function that opens a new tool palette. Meanwhile, a built-in gyroscope sensor lets you alter the orientation of the tools you’re using as you twist the device, offering finer control. Finally, the new pencil gets support for Apple’s Find My network, which should keep minds at rest at the prospect of losing the $129 device.

Finally, to round off Apple’s series of announcements, the entry-level iPad was reduced to $349 — a $100 price cut.
