These mites are found in the human hair follicles, normally found in greater numbers around the cheeks, nose, eyebrows, eyelashes, and forehead. They could also be found in other parts of the body such as arms, chest, and ears. It is a species of tiny mites that have been thought to contribute to hair loss (though this hypothesis is under debate) and live in our pores and hair follicles. The mites vary in size from 0.1mm to 0.4mm long. Mites do not invade internal organs. Under normal conditions they are not harmful, and classified as commensals (the mite benefits but there is no harm or benefit to the host) rather than parasites (where the host is harmed), though under outbreak conditions (demodicosis) they can be harmful. More creepy details here: http://en.wikipedia.org/wiki/Demodex_folliculorum Our skin—two square yards [1.7 square meters] of it on the average human body— is a habitat for roughly as many bacteria as there are people in the United States, for fungi and viruses, and on occasion for mosquitoes, fleas, bedbugs and kissing bugs, blackflies and botflies, lice, leeches, ticks, and scabies mites, which tunnel across the backs of an afflicted person’s hands like moles burrowing in the front lawn.http://ngm.nationalgeographic.com/ngm/9812/fngm/index.html There are follicle mites that live in your eyebrows (and other types of hair), skin mites that cover your face (especially your forehead), and dust mites crawling over every inch of your body and your clothing. They are arachnids, and thus more related to spiders than to insects, and are so small as to be essentially invisible to the naked eye. There’s pretty much nothing you can do to be completely rid of these critters, and, as far as we can tell, they are either beneficial to us or at least not doing any harm—in other words, if we could get rid of them, we might regret it. For instance, skin mites are far more abundant on people with clear, clean complexions than on those with oily complexions and dirty skin, and some believe they actually help keep your complexion clear (i.e., the more you have, the better for your skin). If I were you, I’d worry more about bacteria and fungi, which actually do pose health risks, and just keep washing your hands. http://www.straightdope.com/columns/read/2140/are-there-critters-living-in-our-eyebrows Everything you never wanted to know about the mites that eat, crawl, and have sex on your face  They’re most commonly found in our eyelids, nose, cheeks, forehead and chin. That’s not to say they’re restricted to the face: Demodex has been found in the hairs of the ear canal, nipple, groin, chest, forearm, penis, and butt too. Generally, dry skin is a turn-off for them. They prize bodily real estate that’s flooded with oils (sebum). This explains why they love your face. It might also explain why their numbers are apparently higher in the summer, when hot temperatures ramp up sebum production.http://tinyurl.com/aj2a4xe

Physicists Say Spiderman’s Webbing Could Stop a TrainUniv. of Leicester physics students calculated that the strength of Spiderman’s webbing is proportional to that of real spiders.In Spiderman 2, the superhero uses his webbing to bring a runaway train to a standstill moments before it plummets over the end of the track. But could a material with the strength and toughness of spiders’ web really stop four crowded subway cars? According to Univ. of Leicester physics students, the answer is yes.Read more: http://www.laboratoryequipment.com/news/2013/02/physicists-say-spiderman%E2%80%99s-webbing-could-stop-train
