That's not as easy as it sounds.

Significance work is needed for even 1 tree to survive in a dense urban environment. You can't just stick them in the ground because they won't survive.

Background

Research on the precursors of borderline personality disorder (BPD) reveals numerous child and adolescent risk factors, with impulsivity and trauma among the most salient. Yet few prospective longitudinal studies have examined pathways to BPD, particularly with inclusion of multiple risk domains.

Methods

We examined theory-informed predictors of young-adult BPD (a) diagnosis and (b) dimensional features from childhood and late adolescence via a diverse (47% non-white) sample of females with (n = 140) and without (n = 88) carefully diagnosed childhood attention-deficit hyperactivity disorder (ADHD).

Results

After adjustment for key covariates, low levels of objectively measured executive functioning in childhood predicted young adult BPD diagnostic status, as did a cumulative history of childhood adverse experiences/trauma. Additionally, both childhood hyperactivity/impulsivity and childhood adverse experiences/trauma predicted young adult BPD dimensional features. Regarding late-adolescent predictors, no significant predictors emerged regarding BPD diagnosis, but internalizing and externalizing symptoms were each significant predictors of BPD dimensional features. Exploratory moderator analyses revealed that predictions to BPD dimensional features from low executive functioning were heightened in the presence of low socioeconomic status.

Conclusions

Given our sample size, caution is needed when drawing implications. Possible future directions include focus on preventive interventions in populations with enhanced risk for BPD, particularly those focused on improving executive functioning skills and reducing risk for trauma (and its manifestations). Replication is required, as are sensitive measures of early emotional invalidation and extensions to male samples.

I wonder if this is a materials process (coating the wood then injecting the co2 or something like that) or genetic modification to have it absorb more co2?

Because genetically modified trees that:

  • absorb more co2
  • use less nutrients & water / co2 captured
  • grows and works faster
  • produces wood that is an order of magnitude better than current wood

Is probably like some golden chalice in green carbon capture

Now scientists just have to figure out how much wood a wood engineer would engineer if a wood engineer could engineer wood that traps carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction.

MDA has mild psychedelic effects, because it has some agonist activity at 5-HT2A receptors. If you take enough MDMA occasionally those effects can bleed through towards the tail end of the roll. Very mild visuals at most. Related drugs like 5-MAPB are pure empathogens without psychedelic effects. Methamphetamine at high doses has empathogen effects without psychedelic effects as well. Serotonin release does not induce psychedelic effects. Phenethylamine 5-HT2A agonists can.

Empathogenic effects arise from serotonin release and involve a sense of profound empathy for oneself and others, desire to socialize, anxiety reduction, euphoria, etc while remaining relatively cognitively intact and without meaningful changes in visual perception. These drugs are usually stimulating to some extent. Psychedelic effects arise from biased 5-HT2A agonism and involve vivid, colorful visual hallucinations composed of repeating patterns, loss of sense of self, thought loops, etc without implicit euphoria or anxiolytic effects and in many cases without stimulating effects. Very different experiences.

Have one publicly owned company on the market. As the government owns it, it can incentivise the directors to pursue 'fair' margins however you want to define that.

Other companies either get with the program by competing at the new price level or put themselves out of business. And when it does shareholder payouts, that would be going directly back to the government so it pays for itself.

If it goes out business, spin up another with less foolish operating directions.

Well that's hardly true. I'll throw in a live sources link here in a moment

I've seen that renewables number anywhere between 10 and 50% depending on the prevailing conditions. This December there was no wind blowing at all and it stayed at about 8% for nearly a month.

You're on the wrong sub to be posting that nonsense. First of all, the root system of a tree is usually about as big as the tree is above ground. The carbon stored there should mostly remain in the soil. Second, "used in construction" would store that carbon semi-permanently. Third, even if they were left to decompose, that's not how the decomposition process works at all.

Utilities should never be private. They should be federal only. That way every single American household pays the same rates. Gasoline, electricity, water, natural gas should all be federally regulated. We have had enough with these greedy companies.
