Chemical computer that mimics neurons to be created

A promising push toward a novel, biologically-inspired "chemical computer" has begun as part of an international collaboration.
The "wet computer" incorporates several recently discovered properties of chemical systems that can be hijacked to engineer computing power.
The team's approach mimics some of the actions of neurons in the brain.
The 1.8m-euro (£1.6m) project will run for three years, funded by an EU emerging technologies programme.
The programme has identified biologically-inspired computing as particularly important, having recently funded several such projects.
What distinguishes the current project is that it will make use of stable "cells" featuring a coating that forms spontaneously, similar to the walls of our own cells, and uses chemistry to accomplish the signal processing similar to that of our own neurons.
The goal is not to make a better computer than conventional ones, said project collaborator Klaus-Peter Zauner of the University of Southampton, but rather to be able to compute in new environments.

China's High-Speed-Rail Revolution

China has begun operating what is, by several measures, the world's fastest rail line: a dedicated 968-kilometer line linking Wuhan, in the heart of central China, to Guangzhou, on the southeastern coast. In trials, the "WuGuang" line trains (locally built variants of Japan's Shinkansen and Germany's InterCity Express high-speed trains) clocked peak speeds of up to 394 kilometers per hour (or 245 miles per hour). They have also recorded an average speed of 312 kph in nonstop runs four times daily since the WuGuang's December 26 launch, slashing travel time from Wuhan to Guangzhou from 10.5 hours to less than three.
