https://nautil.us/you-eat-a-credits-card-worth-of-plastic-every-week-17950/ Good summary of current and developing knowledge of effects of microplastic pollution. There are sources that many of us don't give much thought, like cleaning out the lint trap in a clothes dryer. You really don't want to inhale laundry lint, if your clothes contain any polyester fibers.

This issue would be much less of a bother if we just made billiards, frisbee golf, and croquet the primary sports of our nations. And think of the medical resources that would be freed up.

https://www.cnn.com/2022/05/24/perspectives/solar-panels-tariffs-clean-energy/index.html This is incredibly important to our energy future. Why a nation with our manufacturing capacity and resources would be dragging its feet on this is....oh wait, yes, no mystery at all, politics as usual.

Crazier than a sack of tomcats. Bet Roger Penrose would have a good laugh at the guy's microtubule "airbag" theory.

Thanks, I have no idea if this could ever work. And not sure I understand how cooling ground could really produce enough IR to be economically feasible. I was amused to find that Vice magazine ran a story based on that paper, and the writer somehow interpreted mW as "megawatts," instead of milliwatts, and described the power output as megawatts per square meter.

In systems where a corporate sector grows and buys up power bases, wealth tends to concentrate at the top, the bottom half tends towards impoverishment, and crime and violence results. Then people want law and order, and the dictatorial "strongman" arises, promises law and order, and delivers on that (often in brutal fashion). Authoritarian government almost seems like the most natural evolution of late-stage capitalism. Often accompanied by theocracy, as the high priests promise that stern imposition of their moral code will also bring safe streets. (and they will have dogmas that exalt wealth, and make predatory capitalism okay with Gee-Hovah or Whoever)

Possible nighttime counterpart to solar PV power generation. https://pubs.acs.org/doi/10.1021/acsphotonics.2c00223# Looks like it's got a ways to go in term of milliwatts per sq meter, but a cool idea (npi). Maybe would work better in deserts where the surface is losing a lot of heat to space.

I see where Geordie is going. Perhaps one could look at conflicts of applying scientific knowledge and bioethics, a branch of modern philosophy. Science is neutral on the matter of cloning a person. An ethicist can zoom back a bit and try to see if doing so might have unintended consequences, and draw upon other science fields than genetics, to consider the social and psychological effects of cloning. The biotech person might have a "let's do it because we can," and chafe at the philosopher weighing in. BTW, I also would recommend Adam Becker's, What is Real? as @Eise did. Gives a clear look at how a philosophical position can constrict an area of research.

I have expressed optimism about thorium reactors elsewhere on the web. Glad you posted this. It would be wonderful to move away from uranium in reactors. I hope we can add more to this thread as countries explore this option and make progress towards a much safer nuclear power. The huge reduction in waste (with shorter-lived radionuclides) should be reason enough to go this direction.

A nice breakdown on what "systemic racism" means. I don't think progressives can do other than continue to recognize it exists and patiently show how. Idiot side note: I used to have a couple pairs of rather conservative black socks. When I tugged them on, I'd say to my partner, I am putting my Anglo socks on.

You can duck the whole issue, if you take your first bite in the right spot.

Plain text from someone who beat a ten-term incumbent on small donations. “We open doors so others can walk through them.” – Alexandria Ocasio-Cortez "When we talk about the word 'socialism,' I think what it really means is just democratic participation in our economic dignity and our economic, social, and racial dignity. It is about direct representation and people actually having power and stake over their economic and social wellness, at the end of the day." -- AOC We have to stick to the message: What are we proposing to the American people? Not, ‘What are we fighting against?’” - AOC “We don’t have time to sit on our hands as our planet burns. For young people, climate change is bigger than election or re-election. It’s life or death.” - AOC "Solving an unprecedented crisis will require unprecedented ambition.” - AOC

https://www.npr.org/2022/05/21/1099912475/states-courts-debate-18-year-olds-buy-long-guns (About restricting gun purchases by people under 21) Historically, the courts have limited such rights. "The threshold test is what's called 'strict scrutiny,' " says Jeffrey Fagan, a law professor at Columbia University who specializes in gun laws. "It's got to be a compelling governmental interest to limit the right." For that, advocates of a higher minimum age point to brain science. "We know from lots of studies around motor vehicles and drinking and other common types of injuries that this age group is still developing its frontal lobe, impulse control, judgment," says Megan Ranney, an emergency physician and academic dean at the School of Public Health at Brown University. Gun rights advocates, on the other hand, say brain science arguments don't justify taking away the right to armed self-defense from a whole age group. Matt Larosiere is with the Firearms Policy Coalition, which led the challenge to California's law. He says it's bad enough that federal law bans adults under age 21 from buying handguns from licensed dealers; he says it's worse when states bar that same age group from buying rifles and other long guns. "States pass these 18-to-21 rifle bans, and it eliminates completely the ability of young adults of the mechanism of defending themselves," he says. And, he argues that young adults may actually rely on that right more than older people. "There are plenty of young adults in America who are quite often lower-income, or otherwise disadvantaged, not just financially," Larosiere says. "And those are the same people who are the most likely to be violently victimized, and the people most likely in need of an effective mechanism to protect themselves," This legal tension has yet to be resolved. Just last year, a federal judge upheld Florida's new, age-based law limiting gun sales — but he also called this age question "a constitutional no man's land."

My guess is that progs could focus strongly on economic and eco reforms, without so much energy expended on waging culture wars or spreading shallow memes. IOW stay positive. Don't attack, but also don't pretend Trumpism has any merits or that it can be wooed into some "bipartisan" efforts. No sense wasting time on Faux News zombies. Just tell people what progress can be achieved and put your backs into getting everyone to the polls. Make sure every obstacle to voting can be vaulted over by those the GOP wants to disenfranchise. Bring back the Kennedy maxim of "ask not what your country can do for you, but rather what you can do for your country."

I wait loooong decades for someone to ask for this on the web, and it turns out they're using humorous irony. Damn. Another dream deferred. Am still dubious on the position that all this stuff is amenable to a simple solution. Or that (and please don't attack or assist with my bunghole for saying this) teenagers can always be the best judges of their needs and best interests. And judgment circuits in the superior frontal gyrus aren't fully wired until around age 25.

No one ever has their mind changed by what other people post on the Internet. I doubted the truth of that until I read a very persuasive proof on a message board.

@koti Given how incomplete our information is on all these people, I think it would be impossible to say who to believe. Family fights are often ugly and loaded with manipulation. There is a reason that some things end up in a courtroom - just accepting a bunch of "he said" and "she said" statements as a full account in hardly enough to make a rational decision. Also, as someone who has done counseling, I know that people may be "manipulative" because they have very little power over their own lives and can find no other leverage to make their needs known. It's entirely possible that the parents, if they had listened more and been more receptive to Ariel's feelings, would not have triggered quite so much manipulation.

I only know the one geologists use, the Mohs. Though named for a German fellow, his surname also provides the perfect mnemonic (in English) for recalling it....MOHS, measure of hardness scale.

Plus one, and LoL. I think there is a segment of any population that deals with their insecurities by overreacting and showing the world how righteous they are and how depraved others are.

Is that really true? Has a research team attached pulse oximeters to players, or done some other measure of oxygenation? I have been a longtime hiker, on challenging grades, and my impression is that fit women have, if anything, more stamina than men, complain less, need less hydration, and "activate...their hips" quite efficiently (sometimes distractingly).

If we're speaking of the Ruwa, Zimbabwe case, with which I'm familiar, then I don't know what you mean about adult witnesses. Pupils age 6-12 at a private school were the only witnesses, and crude interviewing techniques allowed cross-contamination of their stories. The "environmental message" the students heard was reported only by the psychiatrist who happened to be an ardent environmentalist as well as a believer in alien abductions. And some pupils reported seeing nothing. The event also followed, by only two days, the re-entry of the Zenit-2 rocket from the Cosmos 2290 satellite launch. The booster broke up into burning streaks as it moved silently across the sky, giving an impressive light show across southern Africa. The case is permeated with problems that just don't pass the sniff test.

@Airbrush, since I posted a fairly extensive reply to your OP (mainly directed at your segment "Water") the other day, I am reposting in hopes of getting a reply this time. If my main point was obscured, let me just say that many techno fixes work better when scaled up to blocks or communities, simply because their per-person cost drops so much. Highly engineered systems for SFD (single-family dwellings) may be prohibitive in cost for all but the wealthy. That said, I think there are simpler water recovery options, at homes, for graywater purposes.

Just quick thank you to @Peterkin and @beecee for replies to my post yesterday which a time crunch (ongoing) thwarted my replies. The issues of participation, fun, and phenotype in performance seem fractal in their complexity.

I confess to some confusion over how a purely fitness-based system of eligibility in a mass-plus-strength sport would be more inclusive. Whenever I peer in here, I see good hearted people wanting to make things fair. But removal of gendered sports would instantly remove probably 90% of women from eligibility from mass-strength-fast-twitch fiber dependent games like football. Realistically, what would solve this, Small People's Football? Shotput With Delicate Arms League? Rowing with Lower Upper Body Strength League? Somehow it's hard to see high school or college kids flocking to such offerings.

I think Ockham's razor is useful when evaluating cases like children claiming to have encountered aliens. Given what we know about the psychology of children, there seem to be compelling reasons to consider the ET explanation less likely. A similar response to the notion "they can't all be hoaxes" -- given what we know of the human propensity for trickery, mischief, and a vast array of schemes for self-promotion and/or boosting tourism in places with sagging economies. (And never underestimate the power of boredom, especially in a small town) Our beliefs should never be guided by something being unidentified, except in forming the belief that we may not always get sufficient data about the myriad of small anomalies that occur. I heard an odd sound last night at three a.m. The cat was out, so it wasn't the cat. Nothing in the local news next day. Spouse asleep. Probably will never know what it was. Maybe just some ordinary event, but heard half-asleep. Many things like that in everyone's life. Now multiply by 7.4 billion...
