A new method of measuring rainfall accurately could help to improve flood control. Following a study in the Bolton area, the method, devised by the University of Essex and using dual-frequency microwave links, will now be tested in Italy and Germany.
The recent devastating floods in central Europe have demonstrated the need for accurate rainfall forecasting. To do so, it is essential to be able to measure the amount of rain falling along a particular path, particularly in situations where traditional methods fail.
Professor Anthony Holt of the Department of Mathematics at Essex said: ‘Large computer programmes which run weather predictions every six or 12 hours rely for their output on the accuracy of input information, which includes rainfall.’

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
