Minor League Baseball Players Make Poverty-Level Wages (About 10 percent will make it to the majors.) But even as Major League Baseball is booming, raking in more than $8 billion annually, these players are shut out from the profits. Since 1976, the rock-bottom salary in the majors has gone up more than 2,500 percent; in the minors, it has gone up less than 70 percent. Starting pay for minor leaguers is between $1,100 and $2,150 a month, and only during the season, which can be as short as three months. The average baseball fan knows that minor leaguers aren't getting rich, Broshuis says. But I think the average baseball fan is shocked to know what the salaries actually are..

Overview Retinoblastoma occurs when nerve cells in the retina develop genetic mutations. These mutations cause the cells to continue growing and multiplying when healthy cells would die. This accumulating mass of cells forms a tumor. Retinoblastoma cells can invade further into the eye and nearby structures. Retinoblastoma can also spread (metastasize) to other areas of the body, including the brain and spine. In the majority of cases, it's not clear what causes the genetic mutations that lead to retinoblastoma.

What Are the Causes of Pinpoint Pupils? What are the causes of pinpoint pupils? A: Pinpoint pupils, or abnormal miosis, occur as the result of stimulation to the parasympathetic side of the autonomous nervous system. According to WebMD, drug use, exposure to organophosphates and intracranial hemorrhaging all cause both pupils to shrink.

Scintillator Extruded plastic scintillator material fluorescing under a UV inspection lamp at Fermilab for the MINERνA project. A scintillator is a material that exhibits scintillation — the property of luminescence, when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate, (i.e. re-emit the absorbed energy in the form of light).
