How the Boeing 737 Max Disaster Looks to a Software Developer - IEEE Spectrum
One writer's analysis of how institutional cost-saving pressures led to a pair of airplane crashes. Part of the problem was that they were incented to document it poorly.

Scientists Have 'Hacked Photosynthesis' In Search Of More Productive Crops : The Salt : NPR
This is the first major (very major!) bioengineering project that I've heard about. The photosynthesis-powered process of creating sugar molecules is inefficient; this changes the molecule that does this so it works more effectively.

What I learned from my biggest mistake as an F1 engineer | Andrew Latham | Pulse | LinkedIn
From auto racing: if you mess things up, pay attention. You are outside the normal operating parameters, and you MIGHT discover an advantage there, which you can later exploit more safely.

Memristor minds: The future of artificial intelligence - tech - 08 July 2009 - New Scientist
Resister, inductor, capacitor... those are the basic tools of electronics. But theory said there was a 4th thing: the "memristor". Well, scientists have discovered how to build this 4th thing, and it has become a hot research area for scientists. They are starting to think that it's a key to how synapses work.

The Last Handwoven Bridge, Rebuilt by MIT - Boing Boing
The Incas built a kind of suspension bridge (woven from grass) which was better than anything the Europeans could make until they began using steel. There's still one remaining.

The Humboldt squid beak: Diamond-sharp mystery of the briny deep: collision detection
This squid's beak is one of the hardest organic substances. But the hardness varies along the length, otherwise the squid couldn't hold its own (super hard) beak! Great materials science project!
