A protein's life, up close and personal

(Phys.org)—An EPFL team has developed a technique for spying on the inner lives of cells. For the first time, scientists have used a near-infrared, light-sensitive biocompatible molecule to mark and observe the activity ...

Stabilizing collapsed or shock-damaged buildings

In the gathering gloom of late afternoon, September 11, 2001, building engineers—as well as the rest of the world—watched in horror as the desperately fragile remains of the World Trade Center shifted and settled into ...

(Phys.org)—By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to ...

Microstructural improvements enhance material properties

Exquisite buildings like the Eiffel Tower were made possible because of advances in structural engineering design methods. Truss structures, like the Eiffel Tower, are highly efficient; they can carry the same loads as solid ...

Manmade 'wall of wind' used to test construction

A Category 5 hurricane is a monster of a storm that most people would want to avoid. But, civil engineer Arindam Chowdhury actually recreates those monster hurricane force winds in hopes of helping people better prepare for ...
