Reply to comment by FartyPants69 in Reflexive fear responses tend to linger in people with anxiety disorders, study suggests by chrisdh79

I made passing reference to that. But I work in this field. It is not at all unusual to cross paths with people in professional and public spaces.

Believe it even more if they keep showing you who they are when the spot light is not on.

Reply to comment by Innundator in Pharmacological vitamin C inhibits mTOR signaling and tumor growth by degrading Rictor and inducing HMOX1 expression (Feb 2023) by basmwklz

No new term is needed. It should be called "intravenous" vitamin C. Calling it "pharmacological" is a way of making something that is concrete and simple abstract instead and whoever came up with it is intentionally trying to make this appear more sophisticated than it actually is.

Reply to comment by My_Body_The_Mystery in Scientists create carbon nanotubes out of plastic waste using an energy-efficient, low-cost, low-emissions process. Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide by Wagamaga

No, no, that's not the major problem here. The major problem is that plastic is more or less an indirect byproduct of refining crude oil, so it will always be cheaper to produce new plastic than it is to recycle it. Unless we cut back on our other uses of oil, this will likely never be solved. Hell, we should really be abandoning the use of many plastics due to the microplastic issue, but it's effectively too late for that.

Reply to Scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction by giuliomagnifico

The process appears to be highly intensive (and thus expensive). Certainly more so than cutting down a tree and sawing it into 2x4s, etc. Why not genetically engineer a species of tree that takes up more CO2 (and other elements) while deferring the formation of lignin.

I'm guessing you're referring to his termination in 2017?

If so, worth mentioning that he accused the institution of making him the fall guy for their own failings, his colleagues unanimously resigned in support of him, and he won a defamation settlement against the institution.

This is the wrong place to be looking for engineering and production level products. This is r/science, so what we get is lab results.

If you want Battery Tech or Solar Tech you want to be looking at industry-oriented websites.

For additional context, steel melts at about 2,500 F - less than half the temperature cited in this process.

I agree. All plastics have that little recycling label on the bottom. Easy peasy!!! Then why are we shipping crate after crate to developing countries. It's because the plastics are not seperatable. There are so many variations. (We can recycle the white plastic but not the black plastic take out containers) The lables the food residue. The contamination. The logistics should be hammmered out by the manufacturers in the first place instead of just printing the recyclable label then rejecting it whne its done

>temperatures over 3,100 kelvins

How are commercial procedures less energy-efficient than that?!

From the article: > The plastic, which does not need to be sorted or washed as in traditional recycling, is “flashed” at temperatures over 3,100 kelvins (about 5,120 degrees Fahrenheit). “All we do is grind the material into small, confetti-sized pieces, add a bit of iron and mix in a small amount of a different carbon — say, charcoal — for conductivity,” Wyss said.

Sounds pretty damn scalable to me.

I don't anticipate plastic waste to cause any kind of significant effect on human population anytime soon.

It took life quite a while to find a way to consume dead trees. Are you sure we have that much time?

I think brain inflammation is the one that can cause dementia and such. But I had to reread it a few times as we.
