These exclusive satellite images show that Saudi Arabia’s sci-fi megacity is in full swing
In early 2021, Crown Prince Mohammed bin Salman of Saudi Arabia announced The Line: a “civilization revolution” that would house up to 9 million people in a carbon-free megacity, 170 kilometers long and half a kilometer high but only 200 meters wide. Within the mirrored, car-free walls, residents would be wheeled around in underground trains and electric air taxis.
Satellite images of the $500 billion project, obtained exclusively by MIT The Tech Warrior, show that the line’s sprawling linear construction site is already taking shape. However, visit The Line’s location on Google Maps and Google Earth and you’ll see little more than bare rock and sand.
The odd gap in the image raises questions about who gets access to high-res satellite technology. And if the world’s largest urban construction site doesn’t appear on Google Maps, what else can we not see? Read the full story.
Why babies sleep so much
Babies spend much more time sleeping than awake. Scientists still aren’t quite sure why, but new technologies are starting to shed a little more light on this mystery — and could help reveal what’s going on in a newborn’s rapidly developing brain.
During the first few months, babies’ brains develop connections at a rate of about one million synapses per second. These connections are believed to play a key role in helping babies understand the world around them, laying a crucial foundation for the rest of their lives. Read the full story.

The big story
The future of urban homes is energy-efficient refrigerators
The outdated apartments under the purview of the New York City Housing Authority are not crying out for innovation. The largest landlord in the city, at nearly 1 in 16 New Yorkers, NYCHA has seen its buildings literally crumble after decades of deferred maintenance and poor stewardship. An estimated $40 billion or more, at least $180,000 per unit, would be needed to restore the buildings to working order.
Despite the magnitude of the challenge, NYCHA hopes to solve them. It has launched a Clean Heat for All Challenge, asking manufacturers to develop low-cost, easy-to-install heat pump technologies for building retrofits. The stakes for the agency, the winning company and for society itself can be huge – and good for the planet.
After all, it is much more sustainable to adapt existing buildings than to demolish them and build new ones. Read the full story.
