Blinding dust storms can seriously ruin your plans for a landing on Mars. ESA is adapting the global climate models that we use to forecast our weather on Earth for the turbulent conditions that Mars offers its future visitors.
You could hardly call the weather on Mars pleasant, and presently it is far from predictable. As well as having an average surface temperature of -63°C, and a thin, inhospitable atmosphere of mainly carbon dioxide, last year, a springtime dust storm smothered the entire planet for months. There are also dust devils, which are swirling columns of dust that can reach several kilometres in height that frequently race across the barren surface. Such severe and dusty weather conditions can interfere with the manoeuvres made by spacecraft as they enter an orbit around the planet. For a craft landing on the surface, scientific investigations would have to be put on hold until the weather got better.
Like all travellers, ESA scientists want to make sure that the weather is good when future missions arrive on Mars. They have developed a global atmospheric circulation model for Mars, which uses the same principles as those developed for Earth`s erratic weather patterns.

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...
