Marine biologists want to find out more about the Giant Pacific Octopus, but this elusive creature doesn’t willingly reveal its secrets.
Divers can follow the octopus for short periods, but what’s really needed is an undersea robot that will wait patiently outside the creature’s den, ready to shadow its every move. UA engineering undergrads, in collaboration with students from two other universities, are building a mini-sub to answer this need. In July, they took a prototype to Alaska for testing. Appropriately named Shadow III (and painted a bright yellow that belies its sleuthy assignment) the mini-sub includes a video camera and hydrophones (sonar mikes) to track its prey.
Marine biologists, directed by Professor David Scheel at Alaska Pacific University, will use the sub to track octopuses. Meanwhile, undergrads at Colorado School of Mines are developing the hydrophones under the direction of Tyrone Vincent, an associate professor of electrical engineering. The hydrophones are set up to create bi-aural hearing that will allow researchers to determine the direction from which a sound originates.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
