All women and almost all men (even if they claim otherwise) love to get a nice tan in the summer. In earlier periods, a suntan was generally associated with common folk, field workers, and people who spend most of their day doing hard labor outside. The nobles and all other people of the upper classes despised this and did everything to make their skin even paler than it already is. Now the tables have turned, and sun-kissed skin is considered far more attractive, and a general indicator of good health.
Mice used in the study were shone by a UV-B light at regular intervals of 24, 48, and 72 hours. All of this occurred during a period of 60 days. The focus group that received this treatment every 48 hours developed the darkest skin over this 60-day period.
The main protein in this process is called MITF and it is responsible for much more than just regulating the darkening of our skin. It serves as a defense mechanism as well. As soon as the body is exposed to UV rays for more than a couple of minutes, the MITF starts up the skin’s survival mechanisms. The protein directly influences DNA repair and the recruitment of immune cells to the skin. Only when all of this is finished, does the MITF protein begin the process of melanin production. All this basically means is that if a cell keeps getting exposed to UV rays melanin production stops and the skin loses its protective shield.
There are very few people on this planet who enjoy their work more than Aner Banner. His friends often readily admit that Aner eats, sleeps, and breaths science 24 hours a day. He is always challenging old methods, proposing new ideas, and seeking to solve difficult problems. Aner spends most of the day imparting his wisdom to the young minds of a small elementary school. Thankfully he has also mastered the art of making science come alive for the future leaders of our nation. He is loved and well respected by students, parents, and faculty alike. His motto forever remains “never stop learning.
