How Much of the Periodic Table is in YOU?
About 99.9% of your typical human body is made of just 11 elements from the periodic table. But hiding in that remaining 0.1% are some elements that do some very important jobs to keep you alive and healthy. Including some elements you may have completely forgotten about.

Is Liquid Nitrogen the Future of Clean Energy?
Переглядів 72 тис.12 годин тому
Liquid nitrogen (LN2) might slow down a T1000 for a bit, and it definitely helps make yummy ice cream during a classroom demo, but it has a lot of applications you may have never considered.

    I have multiple autoimmune disorders. And anti-histamines are very helpful and have helped me stay off of biologics. I’m 46 now and may have to give in to, as I just got diagnosed with RA, on top of Lupus/SLE, mixed connective tissue disease, fibromyalgia, CFS/ME. I think I now need to think more about prolonging life and quality of such rather than functionality. But, 20 years after first diagnosis and Plaquenil, I think is quite successful (rarely any steroids). And I have to credit antihistamines quite a bit.

    I both work with many Autistic people (youth and adults) and am Autistic myself. This was an excellent quick discussion about Autism, the complexities involved, the medical perspective and the progress of research. It would have been good if you had more time to emphasise the Autism as Identity part of the Autistic Experience, and I appreciate the brief "neurodivergence" reference. ABA is widely considered problematic primarily as it is focused on stripping away a person's uniqued individuality and teaching them to mimic "average", masking how you perceive yourself, or convinsing you to think you are someone else. Akin to teaching you to deny your own skin colour, or that you have a different sexual orientation. The methods were historically unpleasant and are less so now. Here is a controversial opinion: Learning how to mask if good, so long as you get to chose when to mask. Most of the behaviours that are considered problematic are around an adrenaline response, which can be triggered by a sensory overload, feelings of powerlessness (variety of causes such as ambiguous instructions, missing framework for how to do a thing), or rejection sensitivity (social judgement fears) amongst others. It is smarter to think of Autism as a set of similar base experiences caused by a number of different things, that are then expressed differently. This means that there are many similar cohorts within the umbrella that have similar experiences to each other, but also very different to other cohorts. Even within a cohort, you'll find people who have quite different specific traits and experiences. Another common error is that Autism isn't necesarrily a disability. For many Autistic people, it isn't. However, for some it very much is.

    All I know is that before I got the vaccine I was in great health and very, very rarely got sick. Since I have gotten the vaccine, I am sick at least once every couple of months. My immune system has changed dramatically. And the crazy part is that as far as diet and activity go, I should be the healthiest I have ever been.

    4:43 I remember, in the last election, a local provincial representative for my home town ran, in part, on this myth. The problem is, the reason he ran on this platform is that a majority of local people refuse to acknowledge evidence for harmful climate change that's heavily influenced by people because that's scary and because most of them believe in religious ideas which allow plenty of room to rationalize the idea that everything that happens is the will of their god and that we, as humans, don't have the capacity to have such a profound effect on the world. Unfortunately, people with this perspective are the vast majority across my province.

    I'm a bit confused about C02... let's continue the logic more is better for "plants", it reacts by using more c02 and therefore stopping global warming as c02 is naturally balanced out.... but most c02 is actually locked away in trees and 1/3 is locked away in mycelium in the dirt which helps the trees. All we need are healthy forests which can respond to more c02. Gengis khan changed c02 because he killed the ppl who chopped down trees and forests regrew.

    "Storing enough energy to power 180,000 homes" is um... nonsensical. Literally. Energy and power are not the same thing. You needed to specify _for how long._ Powering 480,000 homes for one second is useless and unimpressive. For 10 minutes could be enough for some load balancing functions. For 24 hours is genuine grid storage and would allow day-night balancing. And longer than that, well... they probably would've recalculated to a bigger number of homes, heh.

    Let’s not forget the most MOST effective thing you can do to reverse and reduce risk of cancer is a whole food plant based diet 🌱 bad diet and environmental factors is exactly why the epigenetic expression altered the tumor suppressor genes. Which can also again be reversed through eating plants. Kale is epigenetically fantastic. The sulphraophane in brocoli spouts is natures chemo too. every vegetable has some sort of cancer fighting polyphenol or attribute. We need to have this info as common knowledge rather than all the drastic drug solutions being the only solution.
