Reply to comment by discretion in Pharmacological vitamin C inhibits mTOR signaling and tumor growth by degrading Rictor and inducing HMOX1 expression (Feb 2023) by basmwklz

No, it is not true. There are some elements of truth (eg, the patentability of vitamin C [and any unpatentable agent] does hinder research, but that ignores that a lot of research is done/funded by not-for-profit/governmental agencies around the world), but it is not a 'global conspiracy' to suppress a miracle cure.

I think it's also worth pointing out that enthusiasm in medicine in general is pretty tempered because with vitamin C we've been here quite a lot before. Eg, IV doses were heavily promoted by some fringe medics as being a revolutionary cure (ie, reducing death by nearly 90%) in sepsis ICU patients, but we now know that risk of death is at the very least not decreased and in is often increased by high doses. I think IV vitamin C is a difficult sell to funders, when there are many such potential avenues to investigate. There is some promising preclinical evidence, eg in this study, and it may be that there will be a new wave of trials as that evidence accumulates to convince people.

Reply to Scientists create carbon nanotubes out of plastic waste using an energy-efficient, low-cost, low-emissions process. Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide by Wagamaga

2 concerns, even if this proves viable: What if virgin materials work better or are cheaper? What if after churning out CNTs by the megaton we discover they're an even worse form of pollution than plastic?

It has several functions which include immunosuppression and fungicide.

The immunosuppressive effects allowed it to be used in organ transplants I believe. And the low rate of cancer in patients using it, lead to the discovery of the mTOR pathway. And it's use in cancer treatment.

I think. Verify everything I've said as it's been a minute since I learned this.

> Same with the monthly battery revolutionizing technology discovered that goes nowhere.

Then again this is always a very slow process. Any kind of battery breakthrough (assuming it's not bogus to make headlines) takes at least a decade to find its way to the consumer market.

So of course you're gonna hear about this revolutionary new thing on paper, then never hear about it ever again, and by the time it's available on the market -probably quietly- then the rest of the industry has also made many other improvements to the point that it's not the huge leap that was promised but more of a "hey the battery on this phone charges faster than on my older one... I think"

Reply to comment by OfLittleToNoValue in Mindfulness-based attention training vastly improves the focus and emotional regulation of high school students by TimTars

The problem with this is, that it is only an intellectual concept when you tell it. How do you noticing without judgement? I could also tell you, that mindfulness is when you feel green. You understand the concept of green, but how do you feel green? Telling or knowing that you need to accept without judgement is practically worthless.

Your unconscious permanently judge its environment and it doesn't care what your conscious intellectual thinks. It still functions in the normal reaction patterns. If something is nice, it wants it and want to keep it. If something is bad, it wants to change it. This reaction pattern needs to change.

The key to know is, how do you train your unconscious to break the lifelong trained reaction patterns? One of the best ways is the vipassana meditation that is attributed to Buddha.

Sit still and make a body scan. The reason for this is, that your unconscious always is conscious about how your body feels. And when you make your body scan, your conscious and your unconscious are on the same place at the same time. Now sit still for an hour without moving. This is uncomfortable and your unconscious want you to move, but your conscious stops your movement. This is the situation you use to train your unconscious to understand to not judge a situation is better than wanting something. If it wanting you to move, it gets more uncomfortable than accepting the situation.

The best way to learn this, is to do a 10 day vipassna retreat, where you meditate 10 hours a day. A 10 day retreat let you reach a practice that is impossible for most to reach in years. They have three times a day a sitting of strong determination in a group where everyone tries not to move for an hour while doing a body scan.

The hour starts with singing and telling you what to do. Than there is silence. In the hour, you only scan your body. Start with the top of your head and try to feel something. If you feel something, move further till you scanned trough your whole body. When you reach your feet, do the same in reverse. When you are in some part of your body and you get a strong sensation in an other part of your body, ignore it. Do your scan without jumping from strong sensation to strong sensations. Don't move, no matter what. Your Eyes should be closed the whole time. This hour is uncomfortable and your unconscious wants you to move. This makes it more uncomfortable. The hour ends with singing for a few minutes (you don't sing).

After some time, you are so sensible to your body feelings, that your conscious and your unconscious feels at the same time that wanting to change the situation makes the hour worse. When you want the hour to end and wish that the singing starts, you instantly feel how your situation got worse. When you stop wishing the hour to end, it gets better. You also feel, that a uncomfortable situation is not uncomfortable all the time. Everything changes all the time. This is when you unconscious learn to accept without judgement.

But i can you tell this, and it will do nothing to you. I can not walk the way for you. Everyone needs to walk the way for himself. It stays an intellectual concept for you and your unconscious still will react within its trained reactions patterns, till you start to teach it.
