Science In Focus: Energy

Interview with Dr. Sallie Baliunas about forms of energy including springs and magnets.,Dr. Sallie Baliunas explains the energy transfers that occur when she pushes down on a spring and then releases it. She explains that she adds potential energy to the spring when she pushes it down, energy that is bound up in the coils. When she releases the spring, the potential energy becomes energy of motion. Some potential energy is used to move air molecules, producing sound, and some is lost to heat

Under the shadow of Tuskegee: African Americans and health care

The Tuskegee Syphilis Study continues to cast its long shadow on the contemporary relationship between African Americans and the biomedical community. Numerous reports have argued that the Tuskegee Syphilis Study is the most important reason why many African Americans distrust the institutions of medicine and public health. Such an interpretation neglects a critical historical point: the mistrust predated public revelations about the Tuskegee study. This paper places the syphilis study within a

Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina

On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from
