Global News
What is global news?
Something that happened or was uncovered recently anywhere in the world. It doesn't have to have global implications. Just has to be informative in some way.
Post guidelines
Title format
Post title should mirror the news source title.
URL format
Post 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] prefix
Opinion (op-ed) articles must use [Opinion] prefix before the title.
Country prefix
Country prefix can be added to the title with a separator (|, :, etc.) where title is not clear enough from which country the news is coming from.

A lot of naysayers in the comments here. Time will tell if the costs and benefits line out to make this useful. I think people don't realize how everything in engineering is about tradeoffs. No building material is perfect and perfect for the environment, but this is an interesting step. Wood is extremely cheap and can be made sustainably. Even if a polymer is used to reinforce the wood that's still less non-biological material than would have been used otherwise. I have read some things about this tech and I am interested to see just how well they can scale up production and market this material. If it requires some exotic construction methods to assemble structures with it then we're probably not going to see wide scale adoption. One potential hurdle is that this material isn't steel and won't be a 1 for 1 replacement of steel, but it's also not wood and won't be a 1 for 1 replacement for wood, so construction crews and engineers will need specialized training to work with it.
It will probably be a few decades before we see this take off if it's going to, but I am excited to see what gets done with it. I could see this getting early adoption in what are essentially cookie-cutter structures deployed in low income countries or barn-like buildings for agricultural use. I'm not a civil engineer but my mind immediately goes to using this for structures that would normally use wood, but with less of it. I am also interested in how this stuff degrades over time and stands up to moisture. Perhaps this could be used in piers and docks where steel is expensive and difficult to maintain if it withstands water well.
