Computer scientist shows how evolution meets computation in new book

Nature and technology may seem worlds apart, but New York University Computer Scientist Dennis Shasha maintains that the natural world can bolster the capacity of today's most sophisticated machines. In Natural Computing: DNA, Quantum Bits, and the Future of Smart Machines, Shasha and co-author Cathy Lazere describe the work of 15 pioneers who have successfully harnessed nature's power in advancing technology.

Spiders at the nanoscale: Molecules that behave like robots

A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular 'robot' made out of DNA to start, move, turn, and stop while following a DNA track.

Superparamagnetic gold nanoshells with tunable optical properties

A solution-phase process has been developed by CNM users from the University of California at Riverside, working collaboratively with the Nanophotonics Group, for synthesizing stable multifunctional colloidal particles composed of a superparamagnetic Fe3O4 core, a gold nanoshell, and a mesoporous silica outer layer.

DNA could be backbone of next generation logic chips

In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world's entire output of silicon chips in a month. So says a Duke University engineer, who believes that the next generation of these logic circuits at the heart of computers will be produced inexpensively in almost limitless quantities.

New coating captures fingerprints on difficult surfaces

CSI notwithstanding, forensics experts cannot always retrieve fingerprints from objects, but a conformal coating process developed by Penn State professors can reveal hard-to-develop fingerprints on nonporous surfaces without altering the chemistry of the print.
