Penn State University chemists and engineers have, for the first time, placed tiny synthetic motors inside live human cells in a lab, propelled them with ultrasonic waves, and steered them magnetically.
The Penn State nanomotors are the closest so far to a “Fantastic Voyage” concept (without the miniature people).
The nanomotors, which are rocket-shaped gold rods ~300 nanometers in diameter and ~3 microns long, move around inside the cells, spinning and battering against the cell membrane.
The nanomotors are activated by resonant ultrasound operating at ~4 MHz, and show axial propulsion as well as spinning.
Manifesto: The 21st Century Will Be Defined By Games Kotaku Australia Systems theory, communications theory, cybernetics, artificial intelligence, computer science — these fields, many of them emerging well before electronic computers, helped...
During 2010-12, noted AI researcher and long-time Humanity+ Board member Ben Goertzel conducted a series of textual interviews with researchers in various areas of cutting-edge science — artificial general intelligence, nanotechnology, life extension, neurotechnology, collective intelligence, mind uploading, body modification, neuro-spiritual transformation, and more. These interviews were published online in H+ Magazine, and are here gathered together in a single volume. The resulting series of dialogues treats a variety of social, futurological and scientific topics in a way that is accessible to the educated non-scientist, yet also deep and honest to the subtleties of the topics being discussed.
Between Ape and Artilect is a must-read if you want the real views, opinions, ideas, muses and arguments of the people creating our future.
