The headline is completely meaningless.

What metric are they using?

Carbon emission in absolute terms, or carbon emission per employee, or carbon emission per dollar of profit?

That makes a huge difference.

Hi there u/tornpentacle, here's a response from Prof Andrey Miroshnichenko, a lead researcher in the Nanophotonics team at UNSW Canberra.

​

>LCD screens use backlight illumination, and light propagates through a liquid crystal cell before entering our eyes. By changing the properties of the liquid crystal cell, the light can be blocked or not. Here we eliminate the relatively thick liquid crystal cell, maintaining the ability to control light propagation properties, making it thinner and lighter.

While fascinating, I think it's a stretch to assume that fighter pilots and astronauts would have similar enough brain structures to be cross-compatible in a study like this.

Yes, they deal with similar things, but Astronauts deal with so much more than fighter pilots do. They also move much faster, experience total weightlessness, and spend extended periods of time away from Earth's gravitational pull.

What can be extrapolated from this study requires a huge asterisk saying "but we can't know for sure since they weren't astronauts and their professions are still markedly different.

You can until a certain age. After a while the contents of the food you're eating catch up with you in the form of health problems, regardless of activity levels or body fat percentage.

In the classroom. So coloring, building blocks, etc. Quiet, creative play.

Apparently some dumb hick hunters were shooting guns too close to the school so they have no outdoor recess during active hunting seasons now. And then the weather is too cold.
