What the Mites On Your Face Say About Where You Came From (sciencemag.org)

sciencehabit writes with news about how the hair mites you carry can be used to determine your ancestry. "Right now, deep in your hair follicles and sweat glands, tiny mites are feeding on dead skin cells, mating, and laying eggs. The microscopic arthropods, known as Demodex folliculorum, live on virtually all mammals—especially their faces—and cause no harm under most circumstances. Now, a new study shows that people of different ancestry carry different subgroups of the bugs, and that the mites' distribution throughout the global population may even reflect how our species has migrated and evolved over the course of history."

Is this cuddling and kissing where we get the first face mites too or are we born with them?

      In fact, for the first two weeks after birth, the immune system is actually suppressed (while the baby has the antibodies conferred from the mother, immune activity is suppressed). It is believed this is to get a head start in populating symbiotic bacteria in the stomach, intestines and skin.

      Presumably a lot of touching confers it as well - our skins are full of bacteria, and on it live some species that we live symbiotically with - being territorial, any foreign invader gets attacked by them before they have a chance to invade us.

      And we live in a very dirty world - there are more foreign cells in and on our bodies than there are human cells, so the merest touches really help spawn colonies on a baby. We're so dirty it probably isn't possible to get anything completely sterile - instead, by sterile we really mean free from contaminants that could cause harm. All the other stuff we live with doesn't really harm us, and we live in peace with them.

      The mites (demodex) are transferred from the skin of the mother to the baby when they cuddle or breastfeed. In dogs the same type of skin mite causes mange and there are breeds of dogs (such as certain red dachshunds) that are very susceptible to demodex and can die from the demodex. In these dogs the transmission can start on the paws and mouth where the puppy touches the mother while breastfeeding.

    The submissions there aren't much different than here, from what I've seen. We get Hugh Pickens here, and they get Hugh Pickens there. If you think Slashdot has a problem with too many political stories, well I think that things are much worse there.

    It's also typical for news to hit Slashdot before it hits Soylent News, and Slashdot isn't known for reporting on issues in a timely manner!

    The moderation over at Soylent News is pretty atrocious, too, from what I've witnessed. The community is quite small, and so a cabal of mods have managed to promote their whacked out ideas, while silencing anyone who questions them. Good comments get modded down, while junk ones get modded up. At least Slashdot's mod community is still big enough to bring some balance.

    I think that Soylent News is a perfect example of what would happen to Slashdot if those on the fringes happened to take over. You get a lot of lunacy, a lot of bad modding, and a site that actually makes Slashdot look pleasant and intelligent.
