African-American achievers in modern science |

"Meet scientists who work with invisible lights, nanomachines, and robots that sing songs.By Keely ParrackFebruary is Black History Month. In celebration of the contributions that African-Americans have made to science, we talked to three black scientists who are making history today with their groundbreaking work.

Hakeem Oluseyi, astrophysicistHakeem Oluseyi, astrophysicist and professor of physics at the University of Alabama in Huntsville, is currently researching the soft X-ray area of the sun's atmosphere. "This is one of the most difficult areas to work with because of the nature of this light and its interaction with matter," he explains. Soft X-ray light is extreme ultraviolet (EUV) light, part of the electromagnetic light spectrum that cannot be seen by the naked eye due to its short wavelength. Because it's at the extreme end of the light spectrum, it's very difficult to detect even with scientific instruments. Dr. Oluseyi has developed a special detector that he plans to send in a rocket to the sun. It will be able to send back new information about this region of the sun's atmosphere"
