NJIT women scientists and engineers use new information technologies to tackle isolation on campus
Integrating new location-aware computer networks
with old-fashioned human networks, researchers at the New Jersey Institute of Technology (NJIT) have developed an innovative solution to the problem of isolation that faces women in the academic science and engineering workforce. The project, NJIT Ad...
With fruit fly sex, researchers find mind-body connection
...cKeown's recent work focuses on understanding gene networks
that control sexual behavior. Research on the topic is often contradictory. Some scientists suggest that the fruitless gene, active only in males, controls courtship and sexual receptivity by repressing female behavior and activating male behavior. O...
