There is such a thing as Sun-synchronous polar orbits (an example).
Dread it, run from it...
No, that's brilliantly executed!
Mmm, high tea... Haven't played that in a while.
It's called a job. You demoncrats wouldn't know anything about that.

I understand the saliva has a benefit for mosquitoes, but not the swelling and the itching (the "unpleasantness" in the title). In essence, our bodies hung this not-otherwise-useful allergic response on something the mosquitoes couldn't/wouldn't/didn't give up and which was firmly specific to their bites, to single them out.
If there was no saliva our bodies would be pressured by natural selection to pick some other mechanism to make their bites unpleasant. An allergy to their chitin or a phobia to the sound of their wings, etc.
Evolutionary pressure from mosquitoes has probably been no small thing.
The way our bodies react to mosquito saliva motivates us to avoid being bitten. Which must have had evolutionary benefits, keeping us away from diseases.
I.e. all those people that didn't mind them and never got itchy from mosquito bites appear to have died out. And mosquitoes really wish that wasn't true.
Ok, I guess the idea that the CMB suggests movement relative to a quasi-absolute reference frame really has become disputed lately... I also found this newer paper by the same authors. It's a pity, I liked the idea.
The image just loaded very slowly for me (i.e. after about 10 seconds). In some posts it never loads at all, but there is a thumbnail in the main screen. This is on sync.
Well, following the main reference in the Wikipedia page leads to this:
The implied velocity for the Solar System barycenter is v = 369.82 ± 0.11 km s−1, assuming a value T0 = Tγ , towards (l, b) = (264.021◦ ± 0.011◦, 48.253◦ ± 0.005◦) [13]. Such a Solar System motion implies a velocity for the Galaxy and the Local Group of galaxies relative to the CMB. The derived value is vLG = 620 ± 15 km s−1 towards (l, b) = (271.9◦ ± 2.0◦, 29.6◦ ± 1.4◦) [13], where most of the error comes from uncertainty in the velocity of the Solar System relative to the Local Group. The dipole is a frame-dependent quantity, and one can thus determine the ‘CMB frame’ (in some sense this is a special frame) as that in which the CMB dipole would be zero. Any velocity of the receiver relative to the Earth and the Earth around the Sun is removed for the purposes of CMB anisotropy studies, while our velocity relative to the Local Group of galaxies and the Local Group’s motion relative to the CMB frame are normally removed for cosmological studies. The dipole is now routinely used as a primary calibrator for mapping experiments, either via the time- varying orbital motion of the Earth, or through the cosmological dipole measured by satellite experiments.
Do any references suggest this dipole is under debate?
Is it controversial? I thought it was pretty established. In Wikipedia it says:
From the CMB data, it is seen that the Sun appears to be moving at 369.82±0.11 km/s relative to the reference frame of the CMB (also called the CMB rest frame, or the frame of reference in which there is no motion through the CMB). The Local Group — the galaxy group that includes our own Milky Way galaxy — appears to be moving at 620±15 km/s in the direction of galactic longitude ℓ = 271.9°±2°, b = 30°±3°.[88] The dipole is now used to calibrate mapping studies.
Relative to the Cosmic Microwave Background. Seems to be the closest thing to an absolute reference frame.
Yes, that's right. There's a "no" at the beginning of the phrase which gives it that meaning (I misread it myself, so I see where you're coming from).

This one is finally more sizeable.
It's a special ethnic adjustment operation.
Her name is a nod to her Indian heritage on her mother's side and in her 2019 memoir, Harris wrote that she pronounced it "Comma-la" and that it means "lotus flower." [...] Still, Trump continues to say "Kah-MAH-la."
I was sure this was going to be the other way around. Strange and less bad than I expected. It's mostly just an accent thing, not a change in sounds.
