Molecular worm algorithm navigates inside chemical labyrinth

With the passage of a molecule through the labyrinth of a chemical system being so critical to catalysis and other important chemical processes, computer simulations are frequently used to model potential molecule/labyrinth interactions. In the past, such simulations have been expensive and time-consuming to carry out, but now researchers have developed a new algorithm that should make future simulations easier and faster to compute, and yield much more accurate results.

Sniffing out terrorists

A new intelligent system has been developed to help identify terrorists carrying explosives. Sensitive electronic noses capture the smell of the explosives; the system processes the acquired data, correlates it with individuals' movements - and ultimately tracks down the suspects.

Minor faults in catalyst impose an obstacle to the chemical industry

One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don't react well. A researcher has discovered the deviations in the miniscule but indispensable particles.

Carbon nanotubes show promise for high-speed genetic sequencing

n the current issue of Science, Stuart Lindsay, director of Arizona State University's Center for Single Molecule Biophysics at the Biodesign Institute, along with his colleagues, demonstrates the potential of a method in which a single-stranded ribbon of DNA is threaded through a carbon nanotube, producing voltage spikes that provide information about the passage of DNA bases as they pass through the tube - a process known as translocation.
