PFAS: Last Week Tonight with John Oliver (HBO)

bremnet says...

I hate it when the uneducated try to explain a complex issue and do a piss poor job of it. Is PFAS a problem? Sure. Are ALL PFAS compounds a problem with regards to their toxicity? No. The small molecule species are problematic because of mobility. The polymeric species are stable as fuck, that's why they were invented and why we use them as seals and barrier layers to isolate corrosive liquids and gases, and why we use them in such things as medical implants. The polymers excel because they are inert and largely unreactive. So - are they all bad? No. Are they all good? No. But it's too late - the fuckwits like Oliver have fueled the Emotional Response bus, and society won't stand for outdated concepts like scientific investigation or rational thought. Eight member countries of the EU are presently on track to restrict or ban all PFAS in any form, sweeping all compounds into the same category with no differentiation between a water soluble perfluorinated molecule like perfluorinated PVME and a one million molecular weight PTFE polymer. If it has a -CF2- moiety in it, it's subject to being banned. Good science doesn't matter any more, the knee-jerk fear mongerers are now making the decisions.

Allassonic/Hot Chocolate Effect

newtboy says...

Works with most hot liquids with powders, I think I first noticed it in a mug of instant hot cider......

https://en.m.wikipedia.org/wiki/Hot_chocolate_effect

The hot chocolate effect, also known as the allassonic effect, is a phenomenon of wave mechanics first documented in 1982 by Frank Crawford, where the pitch heard from tapping a cup of hot liquid rises after the addition of a soluble powder. It was first observed in the making of hot chocolate or instant coffee, but also occurs in other situations such as adding salt to supersaturated hot water or cold beer. Recent research has found many more substances which create the effect, even in initially non-supersaturated liquids.
It can be observed by pouring hot milk into a mug, stirring in chocolate powder, and tapping the bottom of the mug with a spoon while the milk is still in motion. The pitch of the taps will increase progressively with no relation to the speed or force of tapping. Subsequent stirring of the same solution (without adding more chocolate powder) will gradually decrease the pitch again, followed by another increase. This process can be repeated a number of times, until equilibrium has been reached. Upon initial stirring, entrained gas bubbles reduce the speed of sound in the liquid, lowering the frequency. As the bubbles clear, sound travels faster in the liquid and the frequency increases

Dr. Gupta thinks denying Medicinal Marijuana is Immoral

poolcleaner says...

My migraines aren't in remission but I don't suffer nearly as long as I used to since using light psychoactive CBD/THC. Duration of intense pain, loss of vision, loss of feeling in limbs, nausea, vomiting, and the rare seizure has been reduced from 6-12 hours every 2-4 weeks to maybe 2 hours every couple months, sometimes only with nausea, loss of vision, and minor or no pain.

However, the loss of vision, or what my doctors have referred to as visual "premonitions" are still a major pain that I'm not certain will ever go away. Luckily I don't get very many migraines any more. However, if I do get a migraine I still cannot drive or do anything that requires sight. Although I can technically see, it's severely impaired.

The absence or dulling of the pain during a migraine is the greatest thing that has ever happened to me medically. I had a migraine 2 days ago while I was jogging at the park, ran to my car so I could quickly get home before my vision was fucked, and then placed a soluble CBD + THC tablet (Trokie) up into the corner of my mouth where it was slowly absorbed into the facial branches of my carotid artery. After my vision cleared up, I had no headache.

Keep in mind I also take a pure CBD tablet every couple days, so it's not just the one tablet during episodes.

5 Fun Physics Phenomena

robbersdog49 says...

The cereal one is simple, they add iron to the cereal and iron is attracted to the metal.

What surprised me about this is that I'd expect food additives like this to be in some kind of soluble form, just invisibly a part of the food. But when they add iron they literally just add little bits of metal, tiny iron filings. If you put the cereal in a blender a whizz it up to a fine powder and put the magnet through the powder it will come out covered in tiny iron filings.

The cane one is simple too, the finger closest to the centre of mass will always have more of the weight on it, therefore friction is greater on that finger, so the other finger moves more, until it becomes closest to the centre of mass and so on. Each finger gradually moves toward the centre of mass until your fingers are touching. Neither finger can move past the centre of mass because at the point where it lines up with the centre of mass it would take all the weight and the other finger would have no friction at all to push the centre of mass past the other finger.

The phone is a bit of a funny one. It certainly is possible, it's just that it takes more skill to do it. He just hasn't practiced enough. I'm a juggler and just gave this a try. I got clean rotations once every twenty throws or so, which I'm quite pleased with for a first attempt. It feels like something I could learn to do perfectly if I gave it the time (I'm not going to).

The instability is to do with the amount of force required to rotate the phone in each axis. The difficult one is the one that requires the most force and creates the slowest rotation. This means it's easier to add an error in the force when creating the rotation, and the slower rotation means the spin is less stable. All this makes it much harder than spinning it any other way. Harder, but not as impossible as he makes out.

Trolling People Who Park In Handicap Spots Illegally

Retroboy says...

I can think of a few reasons. First one is they just don't see it because they're in a hurry, chatting on their cell phone, or preoccupied. Doesn't matter how clearly it's marked, sometimes it's just people with really strong blinders on. Second is because they don't give a fuck about the rules or about others. Third is they're just going to be a second and there's other ones available so it's just a little sin, kind of like speeding, and everyone else does it, right?. (And confirming for the record that I dislike people that think this way. It's an analysis, not a defense. This is indefensible)

Key point of this video is that the owners of the cars don't know that the spraypaint is water-soluble. If I had mistakenly and unintentionally parked in a handicapped spot and I saw someone spraypainting my car, I'd be furious too. Call the cops, take my license and report me, but don't make me pay for a new paint job.

P.S. Loved the woman telling her guy off "I told you not to park here! I told you not to park here!" Guess he was not one of the 'unintentional' list.

Why would anyone park on a handicapped spot, if there are many free normal parking spots all around it, even closer to the shops?
I call bullshit.

Trolling People Who Park In Handicap Spots Illegally

MilkmanDan says...

I thought of that too, but then I figured that if somebody rolled out in a wheelchair (or with a cane or whatever) the dude could just go over and confess to them that it is a prank with water soluble paint and/or wash it off for them -- he's there filming reaction shots anyway.

Heck, they would probably appreciate the prank even more since they are the ones getting screwed out of their parking places by the other lazy c*nts.

Payback said:

I wonder how many people they painted who were validly parked, but just didn't have the permit showing...

A Guide to Growing Magic Mushrooms

Boise_Lib says...

The mycelium contains psilocybin so the step of growing the fruiting bodies (mushrooms) can be skipped. Psilocybin is water soluble--so the mycelium can be soaked and the solutions filtered and dried.

Does Shyamalan care about Airbender's bad reviews?

xxovercastxx says...

I think a lot of Shyamalan's problems are that he's focused on a different aspect of the movie than most people are.

Let's look at Signs. That was really the first one, I think, that generated widespread disdain. Signs, IMO, was a good story but a bad movie.

Most people talking about Signs would focus on how stupid it is that aliens would invade a planet that's "infested" with water, if you will, when they themselves are water soluble. They would also talk about how unbelievable the aliens were on screen. The "twist" at the end was also way more predictable than 6th Sense and Unbreakable. I'm not saying these aren't valid criticisms; they absolutely detract from the movie as a whole (and ultimately ruined it for me).

But the underlying story about faith, doubt, destiny, self-worth and discovery is wonderful. This is where I think Shyamalan really shines -- in telling stories about characters who learn/discover things about themselves. This is also what I suspect he is focusing on, sometimes to the point of tunnel-vision. He ends up serving a gourmet meal on a cracked plate and a lot of people spend so much time staring at the crack that they forget to taste the food.

I loved The Sixth Sense. Unbreakable is my favorite film specifically because of the underlying story of destiny and self-discovery. It also happens that I really enjoy both the subtle and not-subtle comic book references, so the surface story appeals to me as well. Signs was a misstep but The Village was a move back in the right direction. Lady in the Water was more like Signs; a good beneath a crappy veneer.

Since then his movies have been fairly ordinary, uninteresting, routine Hollywood affairs. I haven't seen any of them.

More than anything, I think it's become popular to dislike him and his movies. Nobody had a bad thing to say about Sixth Sense until Signs came out and all the sudden everyone claimed to have never liked any of his films.

I wish he would go back to doing what he is really good at but also fix the distractions. Serve us our meals on plates that are worthy of the food they're carrying.

Creepy chemicals on your food

notarobot says...

@DrewNumberTwo:

She's not making it up. She's just not citing sources.

Five minutes of internet searching found me this:

"ACUTE TOXICITY

Chlorpropham is moderately toxic by ingestion (2). It may cause irritation of the eyes or skin (2). Symptoms of poisoning in laboratory animals have included listlessness, incoordination, nose bleeds, protruding eyes, bloody tears, difficulty in breathing, prostration, inability to urinate, high fevers, and death. Autopsies of animals have shown inflammation of the stomach and intestinal lining, congestion of the brain, lungs and other organs, and degenerative changes in the kidneys and liver (2)"

Breakdown of Chemical in Soil and Groundwater

Chlorpropham has some potential to contaminate groundwater because it is highly soluble in water and it has only a moderate tendency to adsorb to soil particles (3, 5). Chlorpropham adsorbs strongly to organic matter, so it is unlikely to leach through soils high in organic matter. Chlorpropham does not readily adsorb to montmorillonite or kaolinite clays (4).
Chlorpropham is subject to degradation by soil microbes. Photodegradation and volatilization do not readily occur. Increasing temperatures above 35 degrees C and increasing soil moisture capacity may increase volatilization (4). Soil half-lives from 35 days (3) to 65 days at 15 degrees C or 30 days at 29 degrees C (4) have been reported. Degradation rates are affected by microbial activity and soil moisture levels (4)."

yeah!! pshhhaaa how TOXIC could thallium be... come on.

Wikipedia says:

"Because of its use for murder, thallium has gained the nicknames "The Poisoner's Poison" and "Inheritance Powder" (alongside arsenic).[3]"

"Thallium and its compounds are extremely toxic, and should be handled with great care. There are numerous recorded cases of fatal thallium poisoning.[44] Contact with skin is dangerous, and adequate ventilation should be provided when melting this metal. Thallium(I) compounds have a high aqueous solubility and are readily absorbed through the skin. Exposure to them should not exceed 0.1 mg per m2 of skin in an 8-hour time-weighted average (40-hour work week). Thallium is a suspected human carcinogen.[45] For a long time thallium compounds were easily available as rat poison. This fact and that it is water soluble and nearly tasteless led to frequent intoxications caused by accident or criminal intent.[18]"

"Among the distinctive effects of thallium poisoning are loss of hair (which led to its initial use as a depilatory before its toxicity was properly appreciated) and damage to peripheral nerves (victims may experience a sensation of walking on hot coals). Thallium was once an effective murder weapon before its effects became understood, and an antidote (Prussian blue) discovered.[3]"


No more than 100 micrograms per square meter of skin per 8 hour work day !!!!

Mean Little Dog From The Shelter Just Needed A Hug

raverman says...

<sigh> i hate to be the negative guy but... really? gooey over this? some people are so water soluble.
Lets have some just sightly higher standards eh?

1) The music sucks, didn't need it, just show the video

2) You want to film something? anything? don't hold the camera yourself. It will always look like crap. And it annoys the hell out of me. It's not like you were unprepared for taking the video - You had two cameras. You're just an idiot.

3) You apparently have no idea how to handle a dog at all. Yeah approach a human phobic dog with a leash and back it into the corner. You scare it so badly it defecates - then you want credit for giving it a hug afterwards?
You scared it. It was you! Dogs are social creatures, accepting a leash is an act of trust and a restriction of freedom. If you'd had a shit life and some idiot backed you into a corner trying to tie you up you would freak out too!
You don't think you should have started with building a positive bond first before diving into restraints?

Former Drug Czar Owned. Legalization Debate.

enoch says...

is it my turn to toss in?
good.
lets take mr walters point by point.
1.he is from the hudson institute-(neo-con think tank)deduct 50 points right there.
2.taxable income questionable?ok,i agree here.there is no actual data as of yet.
3.weed is the number ONE reason for drug treatment.
what?where is the former drug czar getting his numbers?
the number ONE abused and treated addictive drug is legal prescription painkillers.even if we used illegal drugs, pot is fourth.(data from A.M.A)
4.weed is responsible for violence and deaths among dealers.
no..its creating a black market that leads to violence and deaths.
its not like a drug dealer can go to the authorities and bitch about another dealer creeping into his turf.this is just bad logic.you can apply the same sentence and just add:coke dealers,pimps,gambling,fights...
when you create a black market,the only way those who RUN that black market can protect their investment is usually through violence,which may lead to deaths,sometimes innocent.
5.mr walters keeps using the term "drugs".
while not wrong,its not entirely accurate."drugs" is an umbrella term which includes ALL drugs i.e :coke,meth,x,heroin etc.
to conflate these very dissimilar narcotics is dishonest and misleading.
6.again mr walters conflates "drugs" with violent behavior.
"many of the arrests found weed on the person"
and?using circular logic to make a point is still circular logic.
so if i got arrested with a playboy in my possesion that would mean im a sexual deviant?thats just weak.
6.marijuana dependency?
first off,doesnt exist.at least not in the way mr walters is portraying it.
THC is fat soluble,which means it takes at LEAST 3 weeks for HALF the THC to leave your body.you have to smoke a tremendous amount,consistently for a very long time to feel any adverse affects if you stop smoking.even then the effects are mild.
7.0.3% is the population percentage in jail for possesion of weed..
thats an outright lie.
that figure is way higher,some as low as 20% and as high as 65%(couldnt get a solid number)but considering that private jails are now the number 9th largest lobby,and are the biggest funders of keeping weed illegal.
well..you tell me what that looks like.
8.more conflation about number of people who use "drugs".
the fact is,a certain amount of the population will use drugs.
its predictable and steady.this number coincides with weed smokers.
i believe the number is 23%,but im not sure and forgot the studies name.
but its around there.

one final note.
some have mentioned it here already,and i totally agree.
if you do something in your own home,harm noone,not even yourself.
how can it be deemed illegal?
even the constitution backs up the dissilution of this ill-thought,inane,archaic and totally useless law.
the man who demonized weed was a man named henry anslinger.
who used the "demon weed" for political purposes,and he did a damn fine job of it.
that was in the late 30's and early 40's.
time to huck this piece of irrelevant legislation out the door.
thank you..and good night.

Codex Alimentarius

snoozedoctor says...

Chogster,
I didn't have time to watch it either, but I did anyway. This is a tough one. I'll try to keep it brief, but that may be hard.

On vitamins and minerals;
If you eat a healthy balanced diet (raise hands please)you get all the vitamins and minerals you need. That's SO not the case in many undeveloped countries, as they rarely eat balanced diets. Taking extra water soluble vitamins, i.e. Vit C, will not hurt you, but it will give you expensive urine. Taking extra fat soluble vitamins can be outright dangerous. Vit A is hepatotoxic in high doses. I recall seeing a patient with end stage liver cirrhosis from chronic cod-liver oil (rich in Vit A) ingestion (how someone can get addicted to that is beyond me.)

There is little credible evidence to prove "extra" amounts of vitamins, above what your body really needs, is of any benefit to your health. Selenium supplementation has been associated with decreased prostate cancer. (So has rapid turnover of spermatozoa and it's more fun than taking selenium.)

The problem with "natural supplements" is several fold. (1) They are still chemicals and, therefore, are not easily differentiated from standard pharmaceuticals, many of which come from plants as well. (2) There is VERY lax quality control in the production of many of these drugs. Assays on potency have shown up to a 100 fold difference between brands that supposedly have the same amount of drug in one pill. (3)Taken in excess, drugs like ephedra are dangerous. It's amphetamine. It will give you a boost in energy, but it also may give you a hypertensive crisis or a fatal arrhythmia.

Medicine is science, and like any scientific endeavor, the proof is in the pudding. There are very few credible studies that demonstrate much benefit to "natural supplements." One speaker in the video, Jim Turner, laments that some of these drugs fall victim to "systematic cause and effect mentality" of the pharmaceutical companies and their "huge, expensive studies." That statement is intellectually bankrupt and I don't think I have to point that out. It takes huge expensive studies to achieve the power of analysis necessary to detect a benefit a drug might have on a relatively rare condition. Say for instance, a drug reduces by 50% the incidence of a complication that happens only once in a thousand patients. You will need to enroll thousands and thousands of patients to reach a power of analysis that will approach statistical significance. It takes, on average, almost a billion dollars to get a typical pharmaceutical drug from synthesis to the US market and that's, in part, due to the rigorous process the FDA requires.

On antidepressants;
Eating right, getting enough sleep, regular exercise and playing in the sunshine are as effective as marketed antidepressants. The side effect of "activation" of SSRIs has been understated. Patients with bipolar illness, rather than typical depression, can experience mania or hypomania, with increased anxiety, racing thoughts and insomnia. That's not what a depressed person needs. While not proven, my personal opinion is that this heightened sense of anxiety may play a possible role in the risk of suicide. Please remember, mentally ill people can hide their illness well. Unforeseen suicides are not uncommon and it's easy to pin the blame on a new medicine, or some other unrelated factor.

I told you it would be difficult for me to be brief. I've practiced for 25 years now.
(1) The FDA is NOT suppressing effective therapies.
(2) All drugs, natural supplements included, should undergo systematic randomized prospective studies to assess their efficacy before being labeled as effective (sadly, that's not always the case)
(3) The drug companies are shamelessly pandering to the public and downplaying side-effects. They have been successful in creating a herd mentality in the U.S. of "I don't feel right, I need a drug." Direct advertising to the public should be BANNED.
