Two new vaccines
Put to work at the same body to the cells that grow uncontrollably is the strategy that seems to be decanted for cancer research. Two studies presented in 2009 at the Congress of the American Society of Clinical Oncology (ASCO), have shown the effectiveness of separate vaccines to improve the prognosis of two common tumors: non-Hodgkin lymphoma and melanoma.
They are two therapeutic vaccines do not prevent the appearance of the disease but do affect its development and increase the life expectancy of patients. The perspective is stretched over a year in the case of lymphoma and in five months in patients with melanoma, a skin cancer with good prognosis if diagnosed early and bad expectations when it is located and extended.
Although both vaccines are administered in combination with chemotherapy, it was demonstrated that their efficacy opens the door to new clinical trials. The melanoma vaccine is made from a protein in the tumor itself and stimulates the production of T cells, a type of white blood cells multiply and seek out protein gp100 to try to destroy it and with it, the malignant cells.

Clock is called an instrument for measuring time. There are several types according to purpose: To determine the current time (wristwatch). Measure the length of an event (stopwatch) ... The clocks are used since antiquity. As has been evolving science and technology of manufacture, new models have emerged with greater precision, better poise and lower cost of manufacture. It is perhaps one of the most popular instruments in the world. There are also various types of clocks and analog or digital (operating with a small electric battery.)

Laser (1961). This device, which uses a quantum mechanical effect, to generate a beam of light with unique properties that make that has a wide range of applications,from medicine to the automotive, telecommunications and aeronautics, was inventedin 1960 by the physicist Theodore Maiman. The English word laser comes from thelaser, an acronym for Light Amplification by Stimulate Emission of Radiation
However, we needed a different measure time appliance accurately
In simpler words, the clock is our position on Earth, with respect to where the sun is at all times. Thus, at 12 days, the sun is overhead, at one day is a bit more towards thesea, and thus moves toward it with each passing hour.
4,000 years ago in Egypt, invented the first watch and was, in fact, the Sundial, only that it could not measure the time when it was night and there was no sun.
