Science The secret lives of mites in the skin of our faces

Microscopic mites that live in human pores and mate on our faces at night are becoming such simplified organisms, due to their unusual lifestyles, that they may soon become one with humans, new research has found.

The mites are passed on during birth and are carried by almost every human, with numbers peaking in adults as the pores grow bigger. They measure around 0.3 mm long, are found in the hair follicles on the face and nipples, including the eyelashes, and eat the sebum naturally released by cells in the pores. They become active at night and move between follicles looking to mate.

The first ever genome sequencing study of the D. folliculorum mite found that their isolated existence and resulting inbreeding is causing them to shed unnecessary genes and cells and move towards a transition from external parasites to internal symbionts.

Dr. Alejandra Perotti, Associate Professor in Invertebrate Biology at the University of Reading, who co-led the research, said, "We found these mites have a different arrangement of body part genes to other similar species due to them adapting to a sheltered life inside pores. These changes to their DNA have resulted in some unusual body features and behaviors."


-----------------------
Yes, these creatures are evolving to be a symbiotic species within humans. They live off our dead skin and we have plenty of that and live in our pores!

    Hmm, about the Headline News, I noticed threads are being moved into the subforum (Health News, Environmental News, etc.). When that happens, the TH Forum Home page loses the articles, and instead would show old articles posted 1 or 2 weeks ago.
  • tom_mai78101 tom_mai78101:
    What do we do with the Home page?
  • Ghan Ghan:
    I added those forums to the filter for that widget.

    Oh nice. They're back. Thanks.
  • tom_mai78101 tom_mai78101:
    Now I think it makes more sense for me to put news in their own subforums, without worry.
  • The Helper The Helper:
    Awesome Ghan thanks! I was purposely not moving the first 15 news articles in Headline news to the different subforums but I guess I don't have to do that now?
  • tom_mai78101 tom_mai78101:
    Question: Is there a way to remove thread redirects? It creates a copy of the moved thread and takes up space, and I am leaning towards wanting to remove them in the Headline News. But if they have an expiration date, I guess I'm fine with it.
  • The Helper The Helper:
    If you move a thread please leave a permanent redirect. You can delete any redirects after 6 months. The redirects are left to help Search Engines find the moved content.
  • tom_mai78101 tom_mai78101:
    What if you move the permanent redirect, not the thread?
  • The Helper The Helper:
    I think that works but I have not messed with it. You can delete redirects though if you have to that will not delete the original thread
  • The Helper The Helper:
    if a redirect ends up in the same forum as the post it goes to though I think the redirect drops or fails or something but they are not bugged out and when you are working on an indirect the original post is safe.

    I found out you can't delete nor hide redirect links to existing threads. It will just stay there. I have no choice now but to start moving thread redirects to News Archive.
  • The Helper The Helper:
    That is not the way that it works for me I can delete redirects you just have to hit refresh sometimes big deletes will take a while as long as moves\
  • The Helper The Helper:
    You don't have to do that you can just leave stuff there in headline news for up to a year it was already down to like 8 months there is no rush.
