The Acoustic Real-time Monitoring System gauges the stability of slopes by listening to soil movement. It is hoped that this radical new system will be more sensitive to slope changes and more robust than traditional methods.
Dr Neil Dixon, Senior Lecturer in Geotechnical Engineering at Loughborough University, said: “Around the world, lots of people are killed every year in landslides. Slopes are not always monitored but, if there is an indication that a slope may fail, instruments like this may help to give early warning.
“Slope stability can reduce rapidly in a matter of hours or even minutes. A warning five or 10 minutes’ earlier than is currently possible might be enough to evacuate a block of flats or clear a road - and save lives in the process.”
The device uses a tube inserted into the slope, with a sensor on top to pick up the high frequency sounds that come from moving soil particles underground. The sensor then sends information to a computer that gives a measure of the slope’s stability.
The system is currently being tested using a trial embankment constructed by the University of Newcastle. The research, which will take three years to complete, is being funded by the Engineering and Physical Sciences Research Council.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
