Reply to Air pollutants have been confirmed to increase the risk of Alzheimer's dementia. Air pollutants enter the lungs through the respiratory tract and cause inflammation, which causes various diseases throughout the body, especially the inflammation of nerves when it reaches the brain. by Wagamaga

Is it a specific pollutant or just general pollutants? If general, does this mean that smokers of any substance increase their risk of Alzheimer's?

Glass doesn't need to be biodegradable and biorecyclable. You can degrade it and recycle it. Crush it up and melt it down.

Let's see some applications. Maybe it has some useful properties? Let's see some manufacturing techniques. Maybe it's cheaper to make, or requires less energy?

Reply to ‘Terminator zones’ on distant planets could harbor life, UC Irvine astronomers say by SnthesisInc

Very interesting ideas. I read this as a perspective possibility as far back is 20 years ago, during a nerdout phase where I was setting up a science fiction game. The idea has always really intrigued me, that there can be a planet where there's this narrow band of habitability scorching death heat of the sunglasses side and the infinite coldness of the dark side

Imagine the science fiction distant future where we could live on such a world, you live in a city that's quite comfortable, but if you go to one side of the extremes of the city the temperature drops 10°, and the other side it raises 10 degrees. While 10 kilometers inone direction and your at a pleasantly hot artificial beach, but 10 km the other way you can go skiing.

Kinda sweet :)

If simple life is as common as I would like to believe it is, I suspect there are many primitive organisms who are surviving on such environments. Not as convinced that such an environment would be well suited to the development of advanced life, but maybe I mean at the end of the day, we really have no idea.

But it's fun to think about

> But the widespread use of persistent, non-biodegradable glass that cannot be naturally eliminated causes long-term environmental hazards and social burdens.

I never quite understood this idea. Most modern glass is float glass. Its made of sand, lime and dolomite.

Want to turn it back into sand? Okay. Crush it. Viola; sand.

Glass is already pretty eco friendly. It lasts for anywhere from years to centuries so rarely needs replacing, most is non toxic, most can be recycled or reused. Not saying this isn't a neat advance, just that the use case might be kind of narrow.
