Epidermis

Several areas of the epidermis of the face show a peculiar yellowish discoloration.

According to the scientific report, published in the online journal Biofabrication, the printed skin has all the essential parts of the natural skin, such as the dermis (the layer of tissue that contains capillaries, nerve endings and other structures), the epidermis (the layer of cells atop the dermis), the stratum corneum (the horny outer layer), and even the collagen, which gives skin its elasticity and mechanical strength.

The outer layer of cells of plants is also called the epidermis.

By a microscope, the bug will be seen to have eight legs, two feelers, and an abdomen something egg-shaped; colour livid red; and in size no bigger than the point of a small needle. They lacerate the epidermis in some way or other, as a small hole is observable where they have been seated; and cause extreme itching and considerable inflammation of the part.

You’d be surprised how much mess 50 people in a large research station can create. Here at the South Pole, where it takes six months for the sun to rise, it only takes two days for a 30 gallon (113 liter) trashcan in the bathroom to be stuffed to the brim and overflowing with used paper towels. Hallway floors turn from bright white to off white in a little less than a week. Dust accumulates, in every corner, on every surface—the collective residue of the station residents’ epidermis, aggravated by dry air, frigid temperatures, and lackluster use of moisturizing lotions.
