New connector for sustainable structures on Earth and in space

As part of his Master's degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures. His initial project has expanded into an online ...

Molecular forces: The surprising stretching behavior of DNA

When large forces act on a heavy beam, for example, in bridge construction, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks ...

How transit scaling shapes cities

The research, published in Nature Sustainability, analyzed data collected from 48 metropolitan areas in the United States, including New York, Boston, Minneapolis and Atlanta, which showed a positive correlation between ridership, ...

A smarter habitat for deep space exploration

In order to explore the moon or Mars, astronauts need smart habitats that will support life and remain operational when they are vacant. To advance the design of autonomous systems for space habitats, NASA is funding a multi-university ...

Dashing the dream of ideal 'invisibility' cloaks for stress waves
