Using Computation to Improve Words: Model Offers Novel Tool for Improving Serious Illness Conversations

Conversations between seriously ill people, their families and palliative care specialists lead to better quality-of-life. Understanding what happens during these conversations – and how they vary by cultural, clinical, and situational contexts – is essential to guide healthcare communication improvement efforts. To gain true understanding, new methods to study conversations in large, inclusive, and multi-site epidemiological studies are required. A new computer model offers an automated and valid tool for such large-scale scientific analyses.

Rapid Rovers, Speedy Sands: Fast-tracking Terrain Interaction Modeling

Engineers and scientists from MIT and Georgia Tech are enabling near real-time modeling of wheels, treads, and desert animals traveling at high speeds across sandy terrains. “Dynamic Resistive Force Theory,” or DRFT, provides a path to speedier granular modeling — and help in designing optimal rough terrain vehicles, like Mars and lunar rovers.
