Self-assembling metal nano-boxes

Microscopic metal boxes that hold a few nanolitres of liquid each have been developed by US researchers. They say the tiny containers could someday be used for precision chemistry or even drug delivery inside the body. The tiny boxes are made from flat templates that self-assemble due to liquid surface tension during the production process. …

Synthetic Biology: PTL Logic

Post-Translational Logic (PTL) devices regulate the post-translational modifications of proteins to define system state and control cell function. Current synthetic biological circuits make use of protein-DNA and RNA-RNA interactions to control gene expression in bacteria– such circuits are examples of Transcription-based Logic. This is an area where Samantha Sutton of MIT is a leading researcher.The …

More superconducting quantum computer details

The Dwave systems superconducting quantum computer is designed only for Maximum Clique NP-complete problems. This is the same as Maximum Independent Set and Minimum Vertex Cover. Max Clique is known to be “really really hard”, in the sense that it is intractable to even get good approximate solutions. It is APX complete From one of …

electric tweezers for optical microscopes

Manipulation of microscopic objects will be for a few thousand dollars instead of the current $250,000 laser based systems for microscopic manipulation The tweezers’ action occurs on a common glass microscope slide embedded with five electrodes. These electrodes create an electric field that can be used to push, pull, move and spin a selected object …

Better Separation of oil and water: good for oilsands

Oil and water can for the first time be mixed and separated on demand thanks to a new, reversible surfactant. Surfactants are a whole category of specialized chemicals that are used in all kinds of industry (cosmetics and many others) The surfactant could be invaluable for extracting abundant but relatively inaccessible oil deposits, such as …
