A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why engineers at the University of Colorado Boulder are building what sounds ...

Finding could have applications in acoustic-levitation-assisted 3D printing, mid-air chemical synthesis and micro-robotics ...

Due to the unique conditions of the space environment and abundant resources, the field investigation and study of the Moon, Earth’s sole natural satellite, represent a crucial milestone in China’s ...

A parasitic worm uses static electricity to launch itself onto flying insects, a mechanism uncovered by physicists and biologists at Emory and Berkeley. By generating opposite charges, the worm and ...

Knowing interaction forces between nanostructures and their substrates is important in nanomanufacturing, such as template-directed assembly. A new mechanical membrane-based AFM (atomic force ...
