Ornithopter with morphing-coupled wingbeat pattern




Cool experiment mimicking raptor flight better than previous examples I've seen. Reminds me of a red-tailed hawk flight. 

You can create an image with artificial intelligence


Try out generating artificial intelligence art at this portal - give a text prompt and it makes an image. 
I asked it to draw a shiny conservative sports car. 

Will The Gulf States Survive When Oil Runs Out?




I was surprised at the level of detail of economic theory he goes into. 
Does he ever really explain why these oil-rich countries will not emerge from oil-based economies into continued prosperity? 

He says the oil-revenue investments are not transparent, the labor force is coerced and trapped, and the banks are constrained by Muslim ideology, and it's hard for them to transition out of oil into other industries because they had no large industries prior to oil which they can fall back on. 

That's pretty comprehensive, but it still doesn't prevent them from reinventing themselves, their banks, and their social investments to permit future prosperity.

Can Groceries Be Delivered TOO Quickly?!




It's worth having prepared food from restaurants delivered quickly, but
11:19 the convenience of delivering groceries within minutes really isn't worth it, if it leads to public nuisance, more dangerous streets, and exploitative labor practices.

These Super Trees Grow Faster and Store More Carbon



Genetically modified popular trees grow faster and capture 53% more carbon. 
3:05 the enzyme rubisco incorrectly latches onto oxygen instead of CO2, requiring redundant energy expenditure to get rid of the inadvertent product. Genetic modification can improve efficiency of this photosynthesis. 
The business model is to sell the carbon credits (from growing this modified tree) to polluters. 

The global food crisis.



7:32 hoarding and export bans exacerbate the issue: farmers within the country stockpile until exports are allowed, or change to a different crop. Elsewhere, food prices are driven even higher.
