According to Dutch researcher Liesbeth Bakker, rabbits prefer grassland grazed by cows. The rabbits benefit from grass that has been grazed short by the cows as this is of a good quality. Furthermore, this grazing relationship leads to a greater diversity of plant species.
The researchers studied a number of plots in the Junner Koeland, a floodplain grassland along the river Overijsselse Vecht. Staatsbosbeheer uses cows to manage the grassland vegetation. However, the numerous rabbits and meadow voles grazing in the area actually consume more grass than the cows.
Rabbits appear to have a preference for grassland that has been grazed by cows. Cows graze away the longer vegetation, leaving shorter grass that is easier for the rabbits to eat. Meadow voles avoid such areas of short grass as this does not provide them with enough cover to escape from their enemies.

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...
