This solution improves the reliability of rail transport and reduces maintenance costs. As reported in the current issue of Pictures of the Future, the system registers the running sounds of wheelset bearings in trains that are under way.
For more than two years, RailBAM has been monitoring 45 trains with a total of 9,000 wheelsets in Southampton, UK. Normally, wheelsets are replaced every 1.2 million kilometers. Because RailBAM can detect damage long before an actual failure occurs, technicians can now replace wheelsets whenever the measurement data shows the first changes.As a result, it has been possible to extend the maintenance intervals for powered and non-powered wheelsets by ten and 50 percent, respectively. RailBAM was developed by Track IQ, a Siemens partner, and is marketed exclusively by Siemens.
Early stages of damage to bearings cause characteristic changes in the running sounds of the wheels. If such alterations appear, the effected wheelset will be replaced the next time the train returns to a depot. In this way, sudden failure can be prevented. Conversely, a wheelset is allowed to remain in service beyond its normal maintenance interval, as long as the monitoring data doesn't show any problems that require attention.
At the moment, RailBAM can be used to monitor trains traveling at speeds up to a maximum of 160 kilometer per hour. However, due to the high level of interest from various rail operators, there are plans to adapt the system so that it can also operate with high-speed trains.

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...
