Almost all plants you can breed to be sterile, paulownia (Empress) trees grow insanely fast, some of the hybrid clones that have been bred are 100% sterile and it can only be propagated through clones, so stuff like that could potentially be a way to help decrease the risk of something like that happening

There are a LOT of other factors as to why we use concrete over wood, strength, toughness and all those other attributes.

Also how is concrete the NUMBER one source of carbon emissions exactly?

Fascinating (the relationship between attention control and emotion regulation was new to me) and activates my confirmation bias, but it's too early to draw any practical conclusions.

>This study compared students who completed the intervention to students who continued with school as usual, collecting self-report survey data from all students both before and after the intervention was administered.

The researchers are aware this is a limitation:

>[T]he school-as-usual control condition makes it impossible to rule out expectation effects as a source of the observed improvements

Hopefully their next experiment will give the control group and their teachers something plausible to do.

EDIT: It's unfortunate that OP's post title adds "Mindfulness-based" (and for that matter "vast") to the title of this paper. This experiment is specifically about an attention training program, not about mindfulness training.

Also, for those interested in what the program entails, there's a brief article here.

Using MOF (Metal Organic Framework) to bind it. Scaling this would be very expensive. Hydrogen fuel production uses MOFs, building a house out of them economically would be quite the feat.

There have been significant advances in advanced wood materials. Treated and compressed wood can now get as strong as kevlar and steel.

That study was for mental health and this one is focus and emotional regulation. The British mental health study had very poor adherance and many students thought it was boring as well with an average number of mindfullness sessions at 1 over the 10 week period while the US study only measured those that completed the training.

Most of that weight is not carbon though, it's mostly water. And I don't know how you think you're going to get mature oak trees in urban densely populated areas anytime soon.

They are. Usually very newswortht when they become major events. The US suffered hundreds of billions in damages in the last 3 years from intense snowstorms in places that very rarely if ever get light snow, getting real snowstorms (laughs in Canadian).

We also have been having arctic lows mixed with warm air causing freezing rain and dangerous conditions in our much shotened winter.

Melting ice cools the air arround it making for colder oceans and atmospheres in summer months. Usually lots of shelf ice melting can impact sheet ice development.
