  1. As usual, life is more complex than some people want us to believe.
    #Science proves there are more than two #sexes:
    #Spectrum

  2. Waterhemp has recently evolved separate M & F sexes from a monoecious ancestor. This study reveals surprising #chromosomal complexity associated with this transition, challenging assumptions of how separate #sexes evolve @PLOSBiology plos.io/46sTg6u

  3. The #Republican president also has sought to block federal spending on #gender-affirming #medical care for those under age 19—instead promoting talk therapy only to treat young #transgender people. In addition, #SCOTUS has allowed him to kick transgender #ServiceMembers out of the #military, even as court battles continue. #Trump also signed another #ExecutiveOrder to define the #sexes as only male & female.

  4. I heard that #TRUMP has issued
    one of his 'executive orders'
    in which he order
    that in #America only 2 #sexes are recognized
    female / male
    (which is not only stupid and cruel, but also scientifically improperly)

    From unpleasant
    America is becoming
    >repulsive<.

  5. The #WhiteHouse removes #Spanish #language #page from its #website and adds ‘#gohome’ #button

    The new president has started off his presidency by taking aim at #immigration and the #LGBTQ+ #community after he signed a raft of #executiveorders, one of which proclaimed there are “only two #sexes”.

  7. “I see a lot of people are talking about #biological #sexes and #gender right now. ...

    If you know a bit about biology you will probably say that biological sex is caused by chromosomes, XX and you’re female, XY and you’re male. This is “chromosomal sex” but is it “biological sex”? Well...

    Turns out there is only ONE GENE on the Y chromosome that really matters to sex. It’s called the SRY gene. During human embryonic development the SRY protein turns on male-associated genes. Having an SRY gene makes you “genetically male”. But is this “biological sex”?

    Sometimes that SRY gene pops off the Y chromosome and over to an X chromosome. Surprise! So now you’ve got an X with an SRY and a Y without an SRY. What does this mean?

    A Y with no SRY means physically you’re female, chromosomally you’re male (XY) and genetically you’re female (no SRY). An X with an SRY means you’re physically male, chromsomally female (XX) and genetically male (SRY). But biological sex is simple! There must be another answer...

  8. Ce sont des évolutions normales et universelles pour les femmes et les hommes qui entrent dans l’âge. Si le mot #ménopause apparaît en 1816, il faut attendre les années 1940 pour entendre parler de "la ménopause virile", vite remplacé par le terme #andropause. Trop souvent considérées comme des pathologies, ménopause et andropause ne sont pas juste des non-dits, ce sont des phénomènes au cœur des rapports sociaux entre les #sexes et les âges, que l’on commence enfin à voir sous un jour nouveau.

  9. My #scientific #Blogarticle linked below discusses aspects of options of more than 2 #sextypes in nature and within animals. An example of a #ciliate with 7 different #sexes is presented with new #scientific #findings by researchers.

  10. Mouse spontaneous #behavior reflects #IndividualVariation rather than #estrous state

    #OpenAccess

    "These findings suggest underlying functional #stability to the circuits that support exploration in female mice, reveal a surprising degree of specificity in individual behavior, and provide empirical support for the #inclusion of both #sexes in #experiments querying spontaneous behaviors"

  11. In species with separate #sexes, #females and #males often differ in their #morphology, #physiology and #behavior. Such sex-specific adaptations imply differences between females and males in the degree of mate competition, mate choice and parental care.
