> Teng Li, a University of Maryland mechanical engineer, created with his colleagues wood that’s as “strong as steel, but six times lighter,” he said Phrases like this make me uneasy. "Strength", especially when used informally like this, is quite ambiguous (e.g. there's a reason we don't make buildings out of spider silk). Overall it's quite an uplifting piece though, and I would certainly like to see such a revival.
