Several cases of tanning addiction have been reported by medical researchers.
The waters are rich in clues about lives lived without sunlight on Earth and possibly on Mars.
Some people use chemical products which can produce a tanning effect without exposure to ultraviolet radiation, known as sunless tanning.
Moderate exposure to the sun contributes to the production of melanin and vitamin D by the body, but excessive exposure to ultraviolet rays has negative health effects, including sunburn and increased risk of skin cancer, as well as depressed immune system function and accelerated aging of the skin.
How do microbes, if any can be found, in these very ancient fluids compare to those discovered in South Africa, and to surface life?
“These are like trapped time capsules,” said Sherwood Lollar.
Noble gas isotopes from radiogenic reactions in the rock accumulate in water over time enabling scientists to calculate that these waters have collected the by-products of water-rock interaction for more than a billion years – possibly even back to the formation of these ancient rocks more than 2.7 billion years ago.
Their discovery will be published in the May 16 issue of Nature.Word of the Day natureall the animals, plants, rocks, etc.Sun tanning or simply tanning is the process whereby skin color is darkened or tanned.The term "tanning" has a cultural origin, arising from the color tan.Its origin lies in the Western culture of Europe when it became fashionable for young women to seek a less pale complexion (see Cultural history below).Sherwood Lollar says the team hopes answers can be found to other pressing questions such as: How widespread are ancient fluids trapped in the subsurface?
