Researchers validate optimum composites structure created with additive manufacturing — ScienceDaily

Additive manufacturing built an early following with 3D printers using polymers to create a solid object from a Computer-Aided Design model. The materials used were neat polymers — perfect for a rapid prototype, but not commonly used as structural materials. A new wave of additive manufacturing uses polymer composites that are extruded from a nozzle…

Meeting minimum guidelines could prevent nearly one in two deaths linked to physical inactivity — ScienceDaily

Keeping physically active or becoming more active during middle and older age is associated with a lower risk of death, regardless of past activity levels or existing health conditions, suggests a large UK study published by The BMJ today. At the population level, meeting and maintaining at least the minimum public health recommendations (150 minutes…
