    NOAA Scientists Are Cleaning Bathrooms and Reconsidering Lab Experiments After Contracts for Basic Services Expire

    A Seattle lab has lost janitorial services, hazardous waste support, IT and building maintenance as it waits for the Commerce Department secretary to personally approve all contracts over $100,000.

    Trash is piling up at the Northwest Fisheries Science Center, part of the National Oceanic and Atmospheric Administration, staffers told ProPublica. Ecologists, chemists and biologists at Montlake Laboratory, the center’s headquarters in Seattle, are taking turns hauling garbage to the dumpster and discussing whether they should create a sign-up sheet to scrub toilets.

    @charontwo: Pretty funny when the one said even 5-year-olds have to say “good game” and admit they lost, then she says that Trump needed Musk to “rig the algorithm ’cause they can’t win on their own merit”. I also liked “Democrats usually balance the budget and end with a surplus”.

    It was remarkable when the other one almost dropped her guard, saying “this person should be take…I mean, these people are too stupid to live”.

    I cannot claim to have read every comment, but I’ve never seen Fortune claim to be the smartest person here. Actually, does not seem like a claim they would make, but I could be wrong.

    I bristled at the “basic reason skills” comment from yesterday. But I get why Fortune would feel comfortable saying that, given some of the comments they have had to endure. At the same time, it was a weird thing to say in the context of that conversation, because the quotes cited were not at all supportive of the claims made.

    But, still.

    Very nice piece today on the changes in bond yields and the value of the dollar, which are going in opposite directions. People are dumping our treasuries and that money is not staying in the US. There are a number of reasons why the US is the wealthiest large country in the world. One of those is because we have been viewed as a safe place to put money and that our fiscal management has been good/responsible, or at least better than anyone else. Trump is exploding this. If that trust goes away, and the dollar is no longer the world’s reserve currency we lose a major advantage and are much poorer in the long run.

    Of note, this might actually eliminate the trade deficit, but it would be because we are too poor to buy imports.

  22. charontwo says:

    The Defector link upthread contained three Trump quotes about tariffs/foreign trade:

    “These countries are calling us up, kissing my ass… They are dying to make a deal.”

    “Please, Sir, make a deal. I’ll do anything. I’ll do anything, Sir.”

    Then in 1913, for reasons unknown to mankind, they established the income tax so that citizens, rather than foreign countries, would start paying the money necessary to run our government. Then in 1929, it all came to a very abrupt end with the Great Depression, and it would have never happened if they had stayed with the tariff policy; it would have been a much different story.

    These being examples of Trump’s increasing shortage of tact, discretion and inhibition.  And, also, of Trump’s very delusional crackpot beliefs about foreign trade and economics.

    America’s economic, military, and soft power accustom the U.S. to getting its way, mostly.  Thus, Trump takes it for granted he gets his way dealing with other nations.  (“L’etat c’est moi” or the royal “we”).

    So, China.

    Trump, most Americans, a lot of Very Smart People on Wall Street, in government etc.believe that, as the U.S. imports so much from China, that the U.S. has the upper hand in any negotiation or confrontation with China over trade. Some of the newsletters I subscribe to say that no, it’s China with the upper hand.

    China has, for years, been growing its own domestic economy so that it is much less reliant on exports. And, it has been diversifying who it exports to. Too, China is a source for some minerals and products not produced in the U.S.

    I believe tariff behavior towards China is partially about dominance – he wants to make Xi grovel, confident he has the upper hand (see the Trump quotes upthread). The culture in far Eastern cultures like Japan and China is very much about preserving face, not losing face. So Xi will be powerfully motivated to avoid being humiliated.

    I leave it to you all to work out the implications. FAFO and the U.S. has surely been FA.

    The less confidence there is in the dollar, the higher the interest rate needed for the U.S. Treasury to sell its longer term notes and bonds. The GOP budget with its $5T deficit may not be very viable, or it might have pretty bad consequences.

    Countries that do not issue the world’s default reserve currency have problems running persistent budget deficits.

    @Liberal Capitalist:

    I read that, too. Same goes for magenta.

    I’ve only read the media reports. I have not spent time thinking about it, either. So, I’m agnostic on this.

    From a purely physical perspective, there is no wavelength associated with purple.

    Purple results from the brain resolving the large interval in wavelength between red and blue. Fair enough. But I saw some explanations that argued that extremely large intervals in wavelength are not “supposed to happen.” I’m not exactly sure what that is supposed to mean. Again, I have not looked at how scientists would explain it formally.

    To declare purple does not exist, or as some headlines put it, our brains “make it up”, strikes me as interpretive. What I mean is that form of the statement carries a lot of philosophical baggage.

    For one thing, our brains fill in gaps in signal constantly.

    Additionally, individuals do not perceive (experience) each color—specific wavelength or not—the same way. I read years back that some individuals have a wider variety of cone cells than average, so they can perceive more granular differences between colors than most.

    Here is the rub, science media is difficult. Communicating science to lay people – a form of abstraction – is difficult. The more information lost in abstraction, the easier it is to communicate the wrong idea. Moreover, scientists who have strong philosophical views, e.g. idealism, realism, often pretend their position must be correct and that can color (ugh) their conclusion.

    @Liberal Capitalist: That’s a pretty good, succinct piece on color and perception of color. It also reminds me of a crack I saw years ago on empiricism and experimentation – all the theorizing, philosophizing, and meditating in the world would not have discovered the existence of ultraviolet.

  31. Flat Earth Luddite says:

    @Liberal Capitalist:

    IIRC, in the science and philosophy classes I took (back when dinosaurs roamed the earth), all colors are actually mearly perceptions of our conscious minds. Colors do not actually exist, they are only concepts and interpretations which we struggle to wrap our heads around.

    Then we get into color photography, and Luddite’s brain siezes up and implodes.

    Blue birds aren’t really blue. We have lots of them up here, and it always amazes me that our minds can play this trick on us. Because they appear not just blue, but vivid blue. I came upon a small flock recently where two birds were going at each other, a mating disagreement probably. They had attracted an audience fluttering around them. It was a cloud of blue bickering birds. One finally hit the dirt just as Sadie and I got really close, but recovered quickly, thankfully, and they all flew away. The end.

    Here is a thread about hedge funds and bonds:

    https://x.com/allie_canal/status/1910701382631371191

    Let’s talk about what’s going on in Treasurys

    10-year is at 4.53% (66 bps swing from Monday’s low), 30-year now at 4.93% (highest since January)

    Experts have told me there are likely multiple catalysts happening at the same time.

    Let’s break them down:

    1. ‘Basis trade’ unwind

    This is a highly leveraged trading strategy most often used by hedge funds.

    The idea is to buy the bonds at a cheaper price & “short” the more expensive futures contract with the hope the two prices will eventually merge

    Think of it this way: You buy a concert ticket for $100 today, but your friend agrees to pay you $110 for the ticket 5 days before the show. As the initial buyer, you know the 2 prices will eventually merge the closer you get to the concert, & can lock in that small profit of $10

    Sounds simple, right? Here’s the problem: Hedge funds use A LOT of borrowed money to do this at scale (sometimes up to 100 times in leveraged bets) which means if the price gap worsens, those small moves can create significant losses

    2. Foreign investors offloading US Treasurys

    Tensions with China have sparked fears that Beijing could aggressively pull back on purchases. Japan is the largest single holder of US debt but China is a major holder too

    In total, foreign investors hold around $7T in US Treasurys:

    (There is a bar graph here)

    3. Investor’s liquidity rush

    Let’s face it: There’s a lot going on right now! With all of the market chaos and uncertainties over Trump’s tariff policy, it’s also possible investors are selling their bonds to hold onto cash as faith in the US economy weakens

    4. Stagflation, recession fears

    With US economic concerns, inflation has been sticky. Even though March’s CPI report was solid, tariffs have muddied the outlook. That, plus a cautious Fed, coul also be leading to thinning Treasury market liquidity.

    Moral of the story: We don’t REALLY know what’s driving the bond market sell-off

    But as
    @KathyJones
    told me:

    “You can do a lot of things, but when the bond market tells you you’re wrong, then you’ve got a problem.”

    @Beth:

    Just as an aside, one way to see the world as those with the red-green variety of color blindness do is to view the movie “O Brother Where Art Thou”, it seems the sienna filter that film was shot through made us all view it as if we were all red-green “blind”. I have a friend who has that condition, and when I asked if he noticed the effect he said that to him it was a film just like any other, except for there being no true whites. That the grass had been all turned to brown? He had no idea what I was talking about. “Looked like normal grass to me.”

    A site that attempts the same thing: https://enchroma.com/blogs/beyond-color/how-color-blind-see

    There are several different types of color blindness, but by far this is the most common.

  43. charontwo says:

    @charontwo:

    Actually, I think I remembered wrong, the actual effect comes from ridges on the surface that are spaced such that the only wavelengths that reflect back are the blue, the other wavelengths cancel out.

    I am gonna need Drew/Fester/Guarneri/Mojito/Connor, the World’s Greatest Businessman, to ‘splain to me how Trump’s sudden fainting spell on China tariffs is a brilliant ploy, and totally not the opposite of what he thought was brilliant yesterday.

    Now, I am no economist, I’m not even a real estate developer, or a game show host, or a rapist, but it seems to me that Trump’s brilliant negotiating tactics means backing down preemptively on tariffing all the things we actually buy from China (phones, chips, TVs) while keeping tariffs on the crap we don’t need (seriously, lumber?). Do I have that right? Did the Great Negotiator just surrender on everything that matters in US-China trade in exchange for what? What did our stable genius get in exchange for his surrender?

    Here’s an explanation of how the rapist got his tariffs slapped down.

    TL;DR: Canada, the EU, and Japan got together and began unloading their US Treasury bond holdings, which are around $2.8 trillion, or just under 1/4 of all the US debt held by foreign governments. This caused prices to go down and yields to go up.

  55. JohnSF says:

    @Kathy:
    My read on the data is that US hedgies began selling bonds at scale to meet margin calls on cratering stocks.
    Then the internationals simply stopped buying, or sold in fairly small scale, so the hedge selling escalated.
    And the message to the US was pretty clear: “If you expect us to help stabilise US bonds, think again, schmuck.”

    There is an old British saying that applies: “Don’t piss on my leg and then say that it’s raining.”

    @Michael Reynolds:

    Trump is the laughingstock of the entire planet.

    It’s not funny, the bond market action is showing a lot of fear.

    It isn’t just Trump, there are people around Trump egging him on with this tariff crap:

    Polling shows the public predominately hates the tariffs, but his people are cherry picking polls of just his supporters to tell him the public likes the tariffs.

    TNR

    Trump’s Own Aides Keep Him in State of Delusion About Tariff Fiasco

    His inner circle is telling him that working-class voters are with him. In the real world, all the tariff chaos gives Democrats an opening to try to crack his vaunted coalition. …

    President Trump’s top allies and advisers know that when the going gets tough, the way to keep Trump from flying entirely off the rails is to slather him with unctuous flattery. “Everybody in Washington, whether they want to admit it or not, knows that this president is right when it comes to tariffs,” White House press secretary Karoline Leavitt lied on Tuesday, plainly intending to calm the Audience of One, who has been raging lately about the domestic and global backlash to his tariff fiasco.

    Now this approach to managing Trump has apparently spilled over into misleading him about public opinion on the tariffs as well. Politico reports that Trump’s inner circle “feels strongly that levying tariffs was a promise made to working-class voters, and that they’re delivering.”

    The basis for this, relates Politico, is private polling that “shows the tariff strategy is playing well among working-class voters who agree with Trump that other nations have taken advantage of the U.S.”

    One of the most fine-grained polls on the topic is a recent national survey from Marquette Law School, a gold-standard poll. It finds that 51 percent of non-college-educated Americans (the standard definition of “working class”) say “imposing tariffs or fees” on products imported from other countries “hurts the economy,” while only 32 percent of them say this “helps the economy.”

    Notably, the Marquette poll also breaks this down by race and education:

    Of all these non-college categories, only non-college white men believe tariffs help the economy, and only by a bare plurality of 44 percent to 40 percent. Non-college white women say tariffs hurt the economy by 42–33. Non-college nonwhite men say this by 68–28, and non-college nonwhite women say this by 60–18.

    So nonwhite, non-college voters are overwhelmingly skeptical of tariffs. This, plus skepticism among non-college white women and even surprisingly high opposition among non-college white men—the molten core of Trump’s base—is why majorities of non-college voters overall think tariffs will hurt, not help.

    By the way, this also holds on income: Majorities of every income group earning less than $100,000 per year (and above, as it happens) say tariffs will hurt the economy.

    That poll is from late March. But is there any reason to think all this has changed in Trump’s favor since he announced the tariffs? No. The specifics are now coming into sharper view. So is the domestic and global backlash.

    It’s true that Trump’s most loyal voters among the white working class might think tariffs will protect them. But if his advisers are telling him this means working-class voters more broadly support them, then they may be operating from a nostalgic, outdated picture of the working class—one that is also likely seductive to Trump.

    @Bill Jempty:

    Perhaps.
    But the actual election results and polling data seem to indicate that MAGA “true believers” are a minority. The primary drivers of voting seems to have been various discontents, not ideology.
    I was inclined to think the last US election would be a squeaker.
    Though I grant, I did not expect the Republicans to take the House and Senate as well.
    I still hope that the US can revert to rational governance in the not-to-distant future.
    The main question for us forriners is: will the Republicans sober up?

    Because otherwise, as Benjamin Haddad (French Minister for European Affairs) said

    “We need to ask ourselves if we want to rely on the voters of Montana, Wisconsin and Michigan to keep Europe safe. Basically, Europe’s security would be flipping a coin every four years.”

    I really dislike the implications of a US is that is MAGA-fied; therefore, perhaps, I’m inclined to try to see a potential good outcome.
    But I’m also really bothering my MP about planning for the less good.
    I suspect his personal office is really getting fed up with me, lol.

    @charontwo: Night vision factors into that too. More rods and fewer cones allows for better night vision. I’ve seen somewhere that all nearly all the critters with good night vision have much less color vision than we do.

    @charontwo:

    … a tiger’s coloring is nice camouflage

    Which raises the question: would there not be a large evolutionary driver for full colour vision?
    Was that simply ruled out by the nature of the eyes and optic neurology?
    Any evolutionary biologists in the house?

    @dazedandconfused:
    Aha!
    Of course.
    Optimise for low-light vision, likely trade-off re colour vision.
    iirc, the ape-line primate colour vision is considered likely to be driven by the need for identifying both edible fruit and predators in daytime.

    It’s more sensible to assume a variety of factors contributing directly and indirectly to massive changes in a complex system, rather than just one.

    @Liberal Capitalist:

    “All colors are made up by the brain. Full stop,” says this visual scientist at Newcastle University in England. They’re our brain’s way of interpreting signals from our eyes.

    That’s the key: vision is nothing at all like “experiencing the wavelengths of light that are entering our eyes”. Even more than for audio or taste or smell, vision is a completely constructed interface to the physical world. It happens subconsciously in the back of your head.

    Ironically, AI researchers picked visual image interpretation (“computer vision”) as one of the first areas of AI to work on, because it seemed so easy and natural. Joke’s on them — it seems easy and natural to us because it’s entirely subconscious and we’ve evolved to be outstanding at it. 70 years later, we’re just starting to figure out how to make computers good at it…

    It’s not funny, the bond market action is showing a lot of fear.

    The bond markets are not noted for their sense of humour.

    Monday will be interesting.
    For arbitrary values of “interesting”.

    @Kathy:
    Indeed; once you are a long way down one evolutionary contingency tree, it’s rather difficult to reverse course.
    But I do wonder: are there any ungulates that have recovered colour vision?
    Or is it not a key driver vs those for scent and hearing?

    @DrDaveT:
    @Liberal Capitalist:
    Old problem.
    All sensations are arguably the product of arbitrary mental response to external stimuli.
    The important lesson of modern science is that philosophical categorisation is less significant than what actually happens regarding organisms, or atoms, or whatever else.

    Reality and perception are distinct, but connected, because a organism must be able to perceive external reality accurately enough to survive.
    Nothing else matters very much.

    @Bill Jempty: Well, I recall my position as being that the Democrats could win, but the win would depend on Democrats convincing all of there constituencies showing up to vote for Harris.

    But you can count me as a “Trump can’t win” if you need to. I understand how threatened you and MR both feel about other people knowing stuff.

    @Bill Jempty: People do gravitate toward reading or hearing stuff that makes them feel good, away from stuff that upsets them.

    The people around “strong men” style leaders like Putin and Trump act on knowing this, which explains the New Republic piece I recently quoted. The people around Trump want to preserve their access, so they tell him stuff that makes him feel good. For example, tell him the voters like his tariffs (based on polling his core supporters), avoid the bad news so many voters are pissed off and/or frightened by them.

    We could literally have elected a baboon, and he’d have done less damage.

    But that is the point, isn’t it? Based on the propaganda-for-profit from hate TV and radio, those that elected him not only expected but demand that he destroy government.

    What need does a survivalist christian “nationalist” need of global trade? There will be plenty for the strongman with guns to take from the weak after the collapse.

    Their fever dreams have told them that they will be the new power in the american wilderness.

    @Bill Jempty:

    I don’t remember anyone else around here thinking Trump would win.

    I was quite vocal about this country not being ready to elect a woman let alone a black woman from day one. Even though Obama sounded white enough I don’t think he would of been able to win after Biden’s term as his first run for the office. Obama had the advantage of rolling in as the economy cratered due to an unpopular republican president.

    The media did an excellent job of carrying water for Trump.
