Ice Tower on Mt Erebus, Antarctica
Giant hollow towers of ice formed by steaming volcanic vents on Ross Island, Antarctica are providing clues about where to hunt for life on Mars.
University of Melbourne geologist, Dr Nick Hoffman has found evidence from recent infra-red images of Mars that similar structures may exist on Mars and, if life is to be found, such towers may be best place to start looking.
Hoffman has drawn attention to strange temperature anomalies in these latest Mars images taken with an infra-red heat-sensing camera on the Mars Odyssey orbiter. These anomalies, he says, fit the signature you might expect from structures formed in similar ways to the Antarctica ice towers.

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...
