    &gt; <i> [...] Your head and feet age at different rates </i>

    Please define "age of a human head", to enable a definition of
    "average #rate of aging of a certain human head, in the course of a certain trial" as ratio between

    - the change (generally: increase) of age of the head over the course of the trial, and

    - the #duration (a.k.a. arclength of timeline) of the head from beginning to end of the trial.

    How exactly would (for instance)

    - number, thickness, color, elasticityy of the head (or beard) hair,

    - dental and epidermal status,

    - acuity of hearing, smell, sight

    be accounted to derive an evaluation of "age of a human head" ??

    (And, surely, "the rate at which your feet aged" is a quantity of profoundly different definition than "the rate at which your head aged";
    quite apart from certain durations being possibly inequal --
    such as the duration of your head, from its birth to its death,
    in comparison to the duratioh of your feet, from their birth to their death.)

    &gt; the Pound-Rebka experiment, demonstrating gravitational redshift.

    Rather than being experimentally demonstrated, gravitational redshift is derived at the outset (from the equivalence principle). It can and should be used to experimentally compare emission frequency and received/absorbed frequency (at the resonance maximum, while emitter and absorber are separated):

    \[ \frac{f_\text{resonance}}{f_\text{emission}} =
    \text{Exp}[ ~ \frac{g ~ \Delta h}{c^2} ~]\times \sqrt{ 1 - (\beta_{\text{resonance}})^2 } \]

    What's experimentally demonstrated, if that's indeed found, is

    \[ \frac{f_\text{resonance}}{f_\text{emission}} \approx 1. \]

    99% of the human race are acting like all 3 monkeys together - blindfolded and repeating "Don't tell me! Don't tell me! Don't tell me!" loudly over and over again to drown out the information

    And 1% are watching, horrified and resigned, as humanity fails to prevent the self-destruction of our own ecosphere

    A quiet gull trailed after Ciara,
not broken, not wild, just there.
When she reached home at last,
it turned down another street,
as if the task was complete.

    Til alle de "journalister" der ikke kender forskel på #mystisk og #mistænkeligt:

    Mystisk betyder noget, der er svært at forstå eller forklare, ofte med en følelse af noget overnaturligt eller uforklarligt.

    Mistænkelig betyder noget, der vækker mistanke eller virker suspekt, som om der er noget galt.

  9. A huge Maya city named Valeriana was discovered in Mexico using Lidar technology. The city, hidden under jungle canopy, had pyramids, sports fields, and causeways, and was home to 30-50,000 people from 750 to 850 AD. The discovery challenges the idea that the Tropics were inhospitable to advanced civilizations.

  15. Mathias Gidsel har imponeret ved OL 2024, hvor han brød flere rekorder. Han blev turneringens MVP og topscorer med 62 mål, hvilket er en ny rekord. Gidsel er den første spiller, der har været topscorer ved VM, EM og OL inden for halvandet år. Gidsel blev desuden for sjette gang i træk valgt til All-Star-holdet ved en stor begivenhed - det var før ham kun lykkedes den legendariske kroatiske spilfordeler Ivano Balic

  16. Researchers in Australia are using sea lions equipped with underwater cameras to explore previously inaccessible parts of the ocean floor. This innovative method has revealed lush seaweed fields, rugged coral-covered rocks, and unique behaviors like a sea lion mother teaching her pup to hunt. The findings aim to enhance our understanding of marine ecosystems and promote better conservation efforts.

    Influences #health and #disease through metabolic, immune, and neurobehavioral pathways. The composition of #gut #microbiota is affected by diet, drugs, and environment.

    Athletes can boost performance by optimizing their gut microbiome, which affects mitochondrial health.

    #Fiber, polyphenols, and healthy fats boost #microbiome and #mitochondrial function, while ultra-processed foods harm gut health. Fermented foods and #probiotics can restore it.

    Unfortunately they also often introduce bugs due to missing code reviews.
