Much research has been conducted relating to uses-and-gratification theory and how audiences select their news medium and message. Research has examined how newspapers, television stations, and social media outlets such at Twitter present news. However, no research has examined from which medium the audience retains the most information. Through the lens of uses-and-gratification theory, this exploratory study used a 4 × 1 experimental design to fill this gap. A convenience sample of 285 students at a large Midwestern university was invited to participate. A total of 122 responded to the invitation (N = 122). While most reported getting the majority of their sports news via television, participants who were presented news in print scored significantly higher on a retention test than did their counterparts who consumed news via television or Twitter. Avid sports fans retained more information, and the presence of links and images in Twitter did have an impact on how much news was retained. Implications for further research are also discussed.

A treadmill with vibration isolation and stabilization designed for the International Space Station (ISS) was evaluated during Shuttle mission STS-81. Three crew members ran and walked on the device, which floats freely in zero gravity. For the majority of the more than 2 hours of locomotion studied, the treadmill showed peak to peak Linear and angular displacements of less than 2.5 cm and 2.5°, respectively. Vibration transmitted to the vehicle was within the microgravity allocation limits that are defined for the ISS. Refinements to the treadmill and harness system are discussed. This approach to treadmill design offers the possibility of generating 1G-like loads on the lower extremities while preserving the microgravity environment of the ISS for structural safety and vibration free experimental conditions.
