URL formatPost URL should be the original link to the article (even if paywalled) and archived copies left in the body. It allows avoiding duplicate posts when cross-posting.
[Opinion] prefixOpinion (op-ed) articles must use [Opinion] prefix before the title. Opinion articles refer to articles that their publisher doesn't explictly endorse.
Country prefixCountry prefix can be added to the title with a separator (|, :, etc.) if the news is from a local publisher who doesn't clearly mention the country.

Right? My first thought reading the title was "okay sure, the crystals get cold. Then what? Are we going to push the crystals outside so they can warm up again, ready to start the cycle anew?". How is "cold crystals" working better to transfer heat than a gas/liquid?

I should read the article, I suppose...

I note that the article states the following: "When the pressure is removed, the process reverses, and the solid can absorb heat from the nearby environment." That would appear to be the opposite of the headline

No it is consistent. Apply pressure => crystal cools, environment heats up. Release pressure => crystals heats up, environment cools.
