In humans, melanin is the primary determinant of skin color. It is also found in hair, the pigmented tissue underlying the iris of the eye, and the stria vascularis of the inner ear. In the brain, tissues with melanin include the medulla and zona reticularis of the adrenal gland, and pigment-bearing neurons within areas of the brainstem, such as the locus coeruleus and the substantia nigr
Researchers have discovered a psychrophilic bacterial strain, called Rhodonellum psychrophilum GL8, at the high altitude Pangong Tso Lake in the Himalayas.
Melanoma accounts for only about 1% of skin cancers but leads to most of the skin cancer-related deaths.
Parkinson’s disease is a neurodegenerative disorder and melanoma is a type of skin cancer but on the surface, these disorders do not seem to have much in common.
Researchers have quantified the diverse types of genomic DNA variations that take place in skin cells and found that mutations from UV light is common.
Thanks to this work, as the journal Trends in Plant Science recently noted, it is now known that functional amyloids serve biological functions in representatives of almost all large groups of living organisms: bacteria, archaea, animals, fungi, and plants.
Risk for melanoma, the most deadly skin cancer, can be estimated long before detection of any suspicious moles, according to a UC San Francisco scientist who led a new study to detect DNA mutations in individual skin cells.
A global collaboration of scientists has more than doubled the known number of regions on the human genome that influence the risk of developing melanoma.
