After positive evaluation by an international team of experts, the Priority Programme (SPP 1385) “The First Ten Million Years of the Solar System” supported by the German Research Council (DFG) has now embarked on its second funding period with twelve new projects on board.
The investigations of the priority programme revolve crucially around material from small bodies like asteroids and comets, the point being that they have not evolved to the formation of a large planet but have remained at the level of small planets called planetesimals. “This means that they have preserved the unchanged relics of dust and rock composition on the way to larger planetary bodies,” says Prof. Trieloff. In this connection, the scientists are investigating sample material from meteorites and comets as well as interstellar material from which the first small bodies and planetesimals took shape. Isotopic dating is used to define more closely the span of time in which asteroids hundred of kilometres across achieved their present dimensions. In addition, the scientists are looking into the heating and the chemical and physical development of planetesimals.

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...
