Studies in mice with otherwise fatal blood clots have shown that targeting a clot-busting drug to regions where blood flow is blocked restores circulation and increases survival with a much lower, safer dose of the drug.

From Desiree D. Dudley, Foresight Director of Development and Outreach: 1)Foresighters Christine Peterson and Desiree Dudley will be speaking at NASA-Ames’ Singularity University this Monday night, August 13th, from 8-10pm. Presentations are from 8-9, and a Q&A panel with H+’s Amy Li and SU’s Jose Cordiero 9-10pm! Topics will include nanotech, biotech, life-extension, and our [...]
Computational insights into a fundamental organic synthesis reaction may lead to the ability to design a catalyst for any desired reaction.
The directed, artificial evolution of genes for enzymes that produce nanoparticles of silicon dioxide and titanium dioxide produced semiconductor structures not seen in nature.
Nanotechnology combines an enzyme and a DNA molecule on the surface of gold nanoparticles to destroy hepatitis C virus in human cells and in a mouse model of disease.
Researchers have configured a 3D printer as an inexpensive, automated discovery platform for synthetic chemistry. A road to more complex molecular building blocks for nanotechnology?
A European Commission-funded video and education portal introduces nanotechnology to students and others.
A new online game allows players to design RNA molecules. The most promising designs are synthesized, and the players given real-world feedback on how well their designs worked.
The 2013 Foresight Technical Conference: Illuminating Atomic Precision will be held January 11-13, 2013 in Palo Alto, CA USA.
Nanoparticles made from specific DNA and RNA strands, homogeneous in size, composition, and surface chemistry, proved superior to other nanoparticles in silencing gene expression in tumors in mouse experiments.
A forest of long DNA strands hanging at known positions from a thin gold foil may provide a method to detect hypothetical particles of dark matter, thought to compose 26% of the universe.
A theoretical study shows that although thermal noise cannot be used to produce useful motion by mesoscale or macroscale machines, it can be used by nanoscale machines without violating the second law of thermodynamics.
The demonstration that the process of DNA replication is more flexible than thought should make it easier to incorporate unusual amino acids into designed proteins, which might make it easier to design novel protein machines.
A new nanomaterial provides a three million-fold improvement in the sensitivity of common medical tests, potentially permitting earlier detection of cancer and Alzheimer’s disease.
Current methods can image individual atoms in complex structures if the structures are crystalline, comprising many identical structures in a regular array. A new method resolves individual atoms in nanoparticles comprising several irregularly arranged crystalline grains.
Tryptophan residues introduced at various positions in a protein chain identify folding intermediates that are too short-lived to be structurally characterized otherwise.
A variety of protein cage structures have been constructed by designing specific protein domains to self-assemble as atomically precise protein building blocks in defined geometries.
How and how soon will nanotechnology play a role in space commercialization?
A set of 310 short single-stranded DNA tiles, plus a few additional short sequences for the edges, has been used to form more than a hundred large, complex DNA objects.
Zyvex Technologies and ENVE Composites have demonstrated the superiority of a proprietary nanostructured composite in downhill cycling.
