Expertise derived from working on the joint NASA-ESA Cassini-Huygens mission to Saturn and its moon Titan is now being applied to underground drilling machines. This is providing tunnelling engineers with an improved ability to virtually "see" some 40 metres into solid rock and pinpoint obstacles ahead.
Trude - the worlds biggest tunnel drilling machine
Tunnel drilling on Earth gains from Saturn/Titan mission
It´s an old miners´ expression: "There is darkness in front of the pick". Billions of years of geological history has laid down complex folds of strata, patterns of faulting and embedded irregular objects in the ground beneath our feet. The character of the earth can and often does change unexpectedly with every metre excavated.
But with modern high-speed tunnelling, sudden geological shifts may damage the cutting head of drilling machines and lead to expensive delays in multi-million Euro excavation projects.
German tunnelling company Herrenknecht AG - famous for drilling the Elbe tunnel in Hamburg using the world´s single largest tunnelling machine - has developed a new method of charting what lies ahead beyond the tunnel face.

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...
