Since advanced nanotechnology will be primarily about complex systems of artificial molecular machines, it is very nice to see the journal Nature begin the month with a very useful overview of molecular machines, presented as a News Feature …
Current nanotechnology is about nanomaterials, nanodevices, and simple molecular machines. Advanced nanotechnology will largely be about complex systems of artificial molecular machines, rather as life can be described as complex systems of biological molecular machines. So any new insight about molecular machines is of potential interest as a signpost toward advanced nanotechnology. …
As we noted back in April, Richard Feynman in his classic 1959 talk challenged his fellow physicists to make the electron microscope 100 times better. A “new super powerful electron microscope that can pinpoint the position of single atoms” had been unveiled at a facility in the UK. While that SuperSTEM is one of only three in the world, a recently demonstrated technology based upon “tabletop extreme-ultraviolet ptychography” brings complementary nanometer-scale resolution to a much smaller (and presumably less expensive) instrument. …
The process of finding novel arrangements of atoms with interesting and useful properties does not appear to be slowing. A hat tip to ScienceDaily for reprinting this news release from the Institute for Basic Science, Korea …
The fourth speaker at the Commercial Scale Devices – Part 2 session, the winner of the 2012 Feynman Prize for Theoretical work, David Soloveichik, presented his prize-winning work “Artificial Biochemistry with DNA” https://vimeo.com/62119584 – video length 29:14. Dr. Soloveichik began his talk by asking if we could recapitulate the feats of biology, specifically computation with networks of molecular interactions, with de novo engineering. …
One prominent area in which nanoscale science and technology is providing a rich pipeline feeding current and near-term improvements in technology is computer hardware, and in particular, solid-state computer memories. One year ago, we cited a breakthrough nanoporous silicon oxide technology for resistive random-access memory (RRAM) developed by the research group of James Tour, winner of the 2008 Foresight Institute Feynman Prize in the Experimental category. Now he appears to have topped this memory architecture with another memory breakthrough. …
About the Foresight Institute
Foreseeing Future Technologies
Advancements in technologies such as nanotech, robotics, artificial intelligence, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information.
Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality.
If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society.
