Acoustic Trauma : Bioeffects of Sound
The work is an investigation into the effects of low frequency sound and infrasound via the design and construction of experimental acoustic emitters. Once installed in a particular space the work will have a profound effect on the surrounding sonic environment and the physiology of human subjects present. This is achieved by the resonant interactions between the subject’s body and the acoustic space.

Damn Interesting » On the Origin of Circuits
It seems that evolution had not merely selected the best code for the task, it had also advocated those programs which took advantage of the electromagnetic quirks of that specific microchip environment. The five separate logic cells were clearly crucial to the chip's operation, but they were interacting with the main circuitry through some unorthodox method– most likely via the subtle magnetic fields that are created when electrons flow through circuitry, an effect known as magnetic flux. There was also evidence that the circuit was not relying solely on the transistors' absolute ON and OFF positions like a typical chip; it was capitalizing upon analogue shades of gray along with the digital black and white.

Complex Systems Group | IU Department of Informatics | Main / HomePage browse
The Complex Systems Group (CX) at Indiana University is part of the School of Informatics. The group was established in 2004 as the first of its kind in the university, although it was not formalized until the formation of the Department of Informatics within the School. CX is meant to foster interdisciplinary research in all areas related to complex systems. It is currently under the coordination of Alessandro Vespignani, Professor of Informatics and Physics.

Primitive intelligence - 27 September 2000 - New Scientist
Even slime mould can work out the shortest route through a maze, scientists have found. They say the discovery shows that the most primitive amoeba-like organisms have some basic computing ability.

Technology Review: Lightning Bolts within Cells
Testing these nanoparticles in the internal fluid of brain-cancer cells, Kopelman found electric fields as strong as 15 million volts per meter, perhaps five times stronger than the field found in a lightning bolt.

Picture-sorting dogs show human-like thought - life - 06 December 2007 - New Scientist
In the training phase, four dogs were simultaneously shown photographs of a landscape and of a dog, and were rewarded if they selected the latter using a paw-operated computer touch-screen. When the computer-savvy dogs were shown unfamiliar landscape and

Scientists Bypass Need for Embryo to Get Stem Cells - New York Times
Two teams of scientists reported yesterday that they had turned human skin cells into what appear to be embryonic stem cells without having to make or destroy an embryo — a feat that could quell the ethical debate troubling the field.
