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.

AltoVolo Opens Orders For Limited Edition Sigma eVTOLs

Early buyers can now reserve build slots for AltoVolo’s 500-mile hybrid aircraft through a new online configurator.

AltoVolo has started taking pre-orders for its first electric vertical take-off and landing aircraft, the Sigma, moving the startup closer to commercial rollout. Customers can now secure a build slot with a £860 deposit and customize every detail online — from paintwork to seatbelt stitching. It’s the first configurator of its kind for a civilian eVTOL, mirroring how luxury car brands let clients tailor performance models before production.

The Sigma runs on a hybrid-electric tilting jet system built for long range and low noise. It can travel up to 500 miles at a 220-mph cruise, and is over 80% quieter than a helicopter. The three-seater weighs just 980kg and can maintain stable flight even if one jet fails. Safety systems include triple-redundant controls, thrust-vectoring stability and a ballistic parachute.

“We will be delivering an ultra-refined hybrid electric aircraft,” said founder and CEO Will Wood. “We believe there are thousands of customers for this type of cutting-edge technology”.

The first 100 units will come with exclusive materials and finishes. AltoVolo is also setting up a global service and maintenance network, with early planning for overhaul schedules already underway. The company’s focus on ownership experience echoes its ambition to anchor itself alongside established aviation brands rather than pure tech ventures.

To help new owners train, the company has built a full-scale simulator that replicates the Sigma cockpit in carbon fiber and leather. Pilots can log time toward a license using the system, aligned with the new US MOSAIC rules that ease certification for powered-lift aircraft. Certification work in Europe and the UK continues in parallel, signaling growing international alignment around light sport and eVTOL regulation.

Noise inside the cabin has become another design focus. Engineers are refining internal vibration levels and developing a responsive soundscape that shifts with each jet’s power load — part feedback, part theatre.

Urban air mobility projects across the Gulf and elsewhere are pushing regulators and manufacturers to meet in the middle. Dubai, Riyadh and Doha have each outlined plans for air taxi corridors this decade. AltoVolo’s hybrid Sigma, sitting between electric promise and aviation realism, looks built for that middle ground.
