>. Unfortunately, western governments seem to be toothless.

How much help did oil companies get early pandemic when prices tanked to below $0?

Reply to comment by AllanfromWales1 in Plants are spreading up mountains faster than thought in North America by BlitzOrion

It is a neat fact. The area of the world that is at high elevation compared to what we are loosing below is significant. We need more aggressive legislation to protect wilderness and clean up industries.

Big plastic could have been solved with proper infrastructure. Instead they ran a campaign to convince the world it was the end users fault. Plants and power stations that break down plastic are band and protested. It’s really frustrating because a industrial problem needs a industrial solution. People don’t believe more reactors and distillation towers are the solution.

Sorry I rant about plastic waste a lot.

Reply to comment by alizenweed in Scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction by giuliomagnifico

But do you know what they also do?

They spread their seeds and make more trees. Those trees then soak up more CO2, which goes into making more wood and tree-seeds. Gee, it's almost like a cycle! A CARBON cycle!

Yea man I know the feeling I’m drowning atm…. My girls father hit her with a suit awhile back from her horrible car accident bc she wouldn’t just give him 50k out of it when she got it to let him play the stock market. Now her wage is garnished all the way down to 400$ per check and I’m currently off work recovering from a full hip replacement at 34Yo from trauma….. I’m still a month or more out from getting back to work…. I push and push myself at therapy but it’s just not fast enough….tbh I’m ready to exit stage left. Take care.

Energy efficient?… Even if you ignore the fact that the wood is washed in NaOH, NaSO3, then boiled in H2O2, then dried in vacuum which have high CO2 footprints, the footprint from making the MOFs is higher than what is captured. Overall, this process increases CO2. This is a gimmick.

Reply to Study of U.S. football coaches finds the more White you look, the more likely you are to be head coach by lolfuys

Casual evidence…

This kind of evidence allows us to understand if there is an association/correlation between a selected variable and better outcomes. However, it cannot tell us whether that selected variable actually causes the improvement or if other variables (confounding) are responsible.

This is more akin to an opinion/editorial piece then legit science. I see lots of blue cars on the road. Blue must be the most popular colour for cars.

>And norway do produce both electric and petrol....

That's because everything is often flogged to the free market. Even if your country produced a lot of energy it won't offset local costs.

e.g. UK electricity costs are due to go up to £0.5 / kwh in April despite the fact half our energy is now produced by renewables and should be dirt cheap.

The article so much better written and well informed than the comments.

Stronger wood could mean using less concrete, which I think is the number one source of carbon emissions. We stopped using wood for huge buildings because it was flammable and concrete and steel were stronger.

But fire prevention has improved incredibly, in building construction, the work that the Underwriters lab does, fire detection and suppression,

Maybe one day we'll see skyscrapers that are closer to carbon neutral.

Reply to comment by Tight-Caterpillar-25 in Psychedelics activate the same receptors as serotonin, so why aren't we always tripping? Psychedelics may cause neuronal plasticity and relieve depression by activating intracellular serotonin receptors that serotonin itself cannot, suggests a new study. by rjmsci

Have you ever done any of these drugs? Metabolic conversion to MDA (which has some 5-HT2A agonist properties) can create some extremely minor psychedelic effects towards the end of the roll as serotonin levels fall but it's not in the same ballpark as any legitimate psychedelic. There's a reason the empathogen/enactogen classification was created.

Reply to comment by Morthra in Depression can lead to memory dysfunction. This study may pave way for new drugs. Results of a large study involving brain scans show that patients with moderate to severe depression have 7-10 per cent fewer serotonin 4 receptors in the brain than healthy test subjects. by Wagamaga

There was a study saying that there is no good evidence that low serotonin levels being related to depression.

SSRI's do work for some people but they aren't fixing any underlying chemical imbalance in the brain. Think of them as a painkiller, they help with the symptoms but aren't fixing some underlying issue.

Not if the USA can help it - seems like this country is headed for a conflict with China to keep it in its place in the "rules-based economic order"

I suspect this is just a correlation thing rather than causative. For your brain to function properly you need to have a good diet, sleep and exercise. If you aren't doing those then your brain isn't going to work properly showing up as things like memory dysfunction and depression.

We have studies that show the causal effect of exercise and have a ideas on the mechanisms why

>Aerobic exercises, including jogging, swimming, cycling, walking, gardening, and dancing, have been proved to reduce anxiety and depression.3 These improvements in mood are proposed to be caused by exercise-induced increase in blood circulation to the brain and by an influence on the hypothalamic-pituitary-adrenal (HPA) axis and, thus, on the physiologic reactivity to stress.3 This physiologic influence is probably mediated by the communication of the HPA axis with several regions of the brain, including the limbic system, which controls motivation and mood; the amygdala, which generates fear in response to stress; and the hippocampus, which plays an important part in memory formation as well as in mood and motivation.

We have studies showing that exercise is just as effective as medicine in treating depression

>Four trials (n = 300) compared exercise with pharmacological treatment and found no significant difference (SMD -0.11, -0.34, 0.12). From https://pubmed.ncbi.nlm.nih.gov/24026850/

Exercise has massive effects on mitochondria, which might be partly a mechanism in relation to depression. >Mitochondria Linked to Major Depression in Older Adults https://today.uconn.edu/2023/02/mitochondria-linked-to-major-depression-in-older-adults/#>

​

Depression is linked to lower brain volume

>Conclusion: Our results suggest that lower CV fitness and exaggerated exercise BP and HR responses in middle-aged adults are associated with smaller brain volume nearly 2 decades later. Promotion of midlife CV fitness may be an important step towards ensuring healthy brain aging.

Sleep is really important, if you aren't sleeping properly you have have a tenfold higher risk of depression,

>People with insomnia , for example, may have a tenfold higher risk of developing depression From https://www.hopkinsmedicine.org/health/wellness-and-prevention/depression-and-sleep-understanding-the-connection

Then there is diet

>The diet may have a significant effect on preventing and treating depression for the individual. A diet that protects and promotes depression should consist of vegetables, fruits, fibre, fish, whole grains, legumes and less added sugar, and processed foods. In the public health nurse’s preventative and health-promoting work, support and assistance with changing people’s dietary habits may be effective in promoting depression.
