Researchers discover vulnerability of a dangerous hospital pathogen

Each year, more than 670,000 people in Europe fall ill through pathogenic bacteria that are resistant to antibiotics, and 33,000 die of the diseases they cause. In 2017, the WHO named antibiotic resistance as one of the greatest ...

Studying diseases with better delivery of gene-editing tools

Stem cells can be used to study the effects of disease on numerous tissue types due to their pluripotency, or ability to produce cells of any type. But using gene-editing tools with them can be challenging, according to Xiaojun ...

Landing therapeutic genes safely in the human genome

Many future gene and cell therapies to treat diseases like cancer, rare genetic and other conditions could be enhanced in their efficacy, persistence, and predictability by so-called "genomic safe harbors (GSHs)." These are ...

Camels' noses inspire a new humidity sensor

Camels have a renowned ability to survive on little water. They are also adept at finding something to drink in the vast desert, using noses that are exquisite moisture detectors. In a new study in ACS Nano, researchers describe ...

Biochip reduces the cost of manufacturing in vitro skin

Researchers from the Universidad Carlos III de Madrid (UC3M), the Universidad Politécnica de Madrid (UPM) and other entities have designed a new biochip, a device that simplifies the process of manufacturing in vitro skin ...

Salamander species can regenerate its skin without scars

Although human skin heals from injuries and wounds, many of us have scars that are left behind. Scar formation happens in adult mammals because skin regeneration does not fully occur. This poses a challenge to physicians ...

Skin

The skin is the outer covering of the body. In humans, it is the largest organ of the integumentary system made up of multiple layers of mesodermal tissues, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, birds. Human skin is not unlike that of most other mammals except that it is not protected by a pelt and appears hairless though in fact nearly all human skin is covered with hair follicles. The adjective cutaneous literally means "of the skin" (from Latin cutis, skin).

Because it interfaces with the environment, skin plays a key role in protecting (the body) against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discolored and depigmented.

In humans, skin pigmentation varies among populations, and skin type can range from dry to oily. Such skin variety provides a rich and diverse habit for bacteria which number roughly a 1000 species from 19 phyla.
