Line dancing bacteria on a chip (w/video)

By changing the direction of a magnetic field, so-called magneto-tactic bacteria are able to make a full U-turn. They can be taught line dancing in this way, inside the tiny micro channels of a lab on a chip.

Self-repairing subsea material

Embryonic faults in subsea high voltage installations are difficult to detect and very expensive to repair. Researchers believe that self-repairing materials could be the answer.

Carbon-trapping nanopore sponges can cut greenhouse gases

In the fight against global warming, carbon capture is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, materials scientists have invented low-toxicity, highly effective carbon-trapping 'sponges' that could lead to increased use of the technology.

Fast, accurate new nanoparticle-based sensor system for screening cancer drugs

Traditional genomic, proteomic and other screening methods currently used to characterize drug mechanisms are time-consuming and require special equipment, but now researchers offer a multi-channel sensor method using gold nanoparticles that can accurately profile various anti-cancer drugs and their mechanisms in minutes.

High-performance phototransistor based on multilayer GaTe

In new work, researchers find Ga ion vacancy is the critical factor that causes the high off-state current, low on/off ratio of GaTe FET and large hysteresis at room temperature through electrical transport measurements at variable temperatures and first-principles calculations as well.

Helping scientists see and measure at nanoscale

If seeing is believing, C.K. Choi has a passion for clarity - in a very tiny world. The assistant professor of mechanical engineering's research lies at the micro-scale, in channels no thicker than a strand of hair.
