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.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
