The struggle to design green buildings amid shifting legal, tech landscape
Holly Samuelson, an associate professor of architecture at the GSD, looks at climate change’s impact on new city and state regulations as architects, designers, and developers try to stay current.…
Sensor enables high-fidelity input from everyday objects, human body
A sensing system called SAWSense takes advantage of acoustic waves traveling along the surface of an object to enable touch inputs to devices almost everywhere. Here, a table is used…
Robotic seal’s gait may be graceless, but it could help save lives
