Self-Assembled Silver Superlattices Create Molecular Machines with Hydrogen-Bond “Hinges” and Moving “Gears”
A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them.

Computing’s invisible challenge
Northeastern University assistant professor of electrical and computer engineering Ningfang Mi recently learned she was one of 42 early-career researchers to win a Young Investigator Award from the Air Force Office of Scientific Research. She plans to use award to figure out a better way to manage the vast amount of information sharing that takes place online—and push that massive technical challenge even further into the background for end users.
Rebar technique strengthens case for graphene
Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handles in a new hybrid material grown by researchers at Rice University. The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but also preserves and even improves the electrical and mechanical qualities of both.

New ‘switch’ could power quantum computing
Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists at MIT and Harvard University have developed a new method for connecting particles — one that could help in the development of powerful quantum computing systems.

Fruit flies, fighter jets use similar nimble tactics when under attack
Researchers at the University of Washington used an array of high-speed video cameras operating at 7,500 frames a second to capture the wing and body motion of flies after they encountered a looming image of an approaching predator.

Air Force R&D group experiments with Google Glass
The BATMAN researchers are experimenting with many probable battlefield scenarios, including how Google Glass could be used by ground forces to help aircraft acquire targets or how it could work as a communications device between combat controllers and overhead aircraft.
