2011 Foresight Institute Prize in Communication deadline is Sept. 30, 2011

The nomination process for the 2011 Foresight Institute Prize in Communication is now open. The prizewinner for the Communication Award will be awarded a $1,000.00 prize plus a physical award. …

2011 Foresight Institute Feynman Prize deadline is September 30, 2011

The nomination process for the 2011 Foresight Institute Feynman Prize is now open. Two prizes in the amount of $5,000 each will be awarded to the researchers whose recent work has most advanced the achievement of Feynman's goal for nanotechnology: molecular manufacturing, defined as the construction of atomically-precise products through the use of molecular machine systems. Separate prizes will be awarded for theoretical work and for experimental work. The winners of this year's prizes will be announced at a venue to be announced. …

A four-artificial-neuron network from 112 DNA strands

Following up on their recent accomplishment of building a computational circuit from 74 small DNA molecules, Caltech researchers assembled 112 DNA strands into four artificial neurons that they trained with four pieces of information about four scientists. The artificial neural network can then play a game in which it properly answers questions about the identity of a scientist that the player has in mind even when the player gives it incomplete or wrong information. …

DNA nanotechnology provides detailed monitoring of single cells

A short segment of single-stranded DNA artificially evolved to bind to a particular protein growth factor has been adapted to make a molecular sensor for that factor. Upon binding the growth factor the DNA changes shape, bringing two fluorescent dye molecules closer together, thus producing an optical signal. After chemical attachment of the sensor to the membranes of an adult stem cell, and transplantation of the stem cell into a mouse where it homes to the bone marrow, the sensor reports on the environment of the cell. …

Foresight's recent past president honored by his undergraduate university

Foresight's recent past president J. Storrs "Josh" Hall was awarded the 2011 Achievement Award in the Sciences from his undergraduate alma mater Drew University …

Nanotechnology therapy for head and neck cancer shows promise

…Researchers at the University of Michigan have demonstrated in a model using immunocompromised mice (so that they do not reject human tumors) that dendrimers targeted to tumors and carrying anti-cancer drugs show great promise as potential therapy for head and neck cancer. …

American Chemical Society grant to study molecular gears

The American Chemical Society Petroleum Research Fund has awarded a grant to study the development of molecular gears for use in future molecular machines. …

First synthetic organ transplant made possible by nanotechnology

Nanotechnology has played a critical role in the first synthetic organ transplant, a trachea (windpipe). A patented nanocomposite of unreported composition was used to form a scaffold exactly the same size and shape as the patients own windpipe, which was then seeded with adult stem cells from the patient's own bone marrow. …

An evolution machine to accelerate nanotechnology development?

Proposals for assembling molecular machine systems from parts based on biopolymers usually take the approach of computationally designing proteins, RNA, or DNA molecules to serve as devices or as components of supramolecular systems. An alternative approach that has also been pursued is directed evolution in the laboratory …

Handling flexible parts in RNA nanotechnology

As a road to advanced nanotechnology, RNA nanotechnology offers greater structural and functional versatility than does DNA nanotechnology. A disadvantage of multiple structural motifs, however, is that finding small molecules that bind specifically to an RNA molecule is more difficult than, for example, finding small molecules that bind specifically to protein molecules, which exhibit single defined structures. …

Foreseeing Future Technologies

Advancements in technologies such as nanotech, robotics, 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.
