With biotech fundamental to several paths to advanced nanotechnology, a way to do biotech experiments in the cloud offers small groups the chance to quickly test their ideas.
B.R.AI.N.S., Berkeley BioLabs, and Foresight Institute to build an open source biological parts repository and design and distribute a line of “How-to Build Biological Machines” educational kits.
Enveloped DNA nanostructures were developed to escape attacks from nucleases and the immune system, opening a path to ever more sophisticated DNA nanomedical devices.
The photos from the 2014 Foresight Technical Conference highlight entrepreneurial efforts in space, biotechnology, and life extension.
The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.
A swinging DNA arm added to a DNA scaffold makes it possible for two enzymes attached to the scaffold to complete a coupled chemical reaction.
A bacterium has been engineered to stably propagate a DNA written with six letters instead of the usual four, greatly expanding the number of amino acids, both natural and synthetic, that can be genetically encoded. Further work could lead to novel proteins incorporating these additional amino acids, and from there to novel materials, devices, and machines.
By targeting the protein that attaches a type of immune cell called neutrophils to blood vessel walls where they cause serious tissues damage, the neutrophils are released and returned to the circulation to resume their normal functions.
RNA interference provides potential cures for various diseases by silencing the expression of specific genes in specific organs, but delivering the RNA molecules to the right place is very difficult. A novel nanoparticle provides unprecedented efficiency in silencing target genes in liver cells.
The concern of the US GAO for a gap in nanomanufacturing is well-placed, but it is only half of the problem with the limited US vision of the impact of nanotechnology on the future world economy.
Using struts made of DNA to stiffen polyhedral corners, scientists have build rigid DNA cages an order of magnitude larger than previous DNA nanostructures, and only one order of magnitude smaller than bacterial cells.
A “sense of energy, momentum, and collegiality throughout the weekend” united attendees hearing about the integration of nano-engineered devices and materials into more complex systems, and the integration of nanoscale technologies into diverse applications.
A very large community of online gamers has consistently produced RNA designs that outperform the best design algorithms by a large margin. Can online gamers designing RNA, protein, and other molecules contribute to the development of atomically precise manufacturing?
A reconstituted high-density lipoprotein nanoparticle reduces inflammation in advanced atherosclerotic plaques in mice. Will it work in humans to prevent repeat heart attacks and stroke?
A DNA clamp engineered for higher specificity and higher affinity may improve cancer diagnosis and treatment and may also mean better control over building nanomachines.
A possible forerunner to a future molecular assembly line uses an artificial DNA motor to transport an artificial nanoparticle along a carbon nanotube track.
A study of RNA structures actually present in cells reveals that cells spend energy restricting thermodynamically driven RNA folding so that fewer RNA structures are found in cells than in test tubes.
A collection of open access journals on a variety of topics provides a very useful entry point to the rapidly growing collection of scientific, technical, and scholarly research that is not hidden behind pay walls.
Using DNA nanotechnology to control and organize molecular motors and the molecular tracks that they run on, a novel nanotrain transports molecular cargos tens of micrometers.
