Higher concentrations of melanin -- the color pigment in skin and hair -- may indicate increased susceptibility to nicotine dependence, U.S. researchers say. We have found that the concentration of melanin is directly related to the number of cigarettes smoked daily, levels of nicotine dependence, and nicotine exposure among African Americans, Gary King of Pennsylvania State University says in a statement. The researchers recruited 150 adult African-American smokers from three sites in inner...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
