Heavy metals can trigger widely varying stress reactions in plants. A team at the Campus Vienna Biocenter was now able to provide evidence for this in a research funded by the Austrian Science Fund (FWF). The results, now awaiting publication, are an important basis to comprehend how plants cope with an increase in heavy metal concentrations in the soil - and how these abilities can be profitably utilised.
Plants are capable of a variegated spectrum of stress reactions. Prof. Heribert Hirt and his team at Campus Vienna Biocenter have now proved that plants can distinguish even between different heavy metals.
Adverse environmental conditions can cause enormous stress in plants. As sedentary beings they are at the absolute mercy of these conditions. Nevertheless, in order to grow and flourish, they have developed a comprehensive series of stress reactions. The recent work by the team of Prof. Heribert Hirt and Dr. Claudia Jonak at the Campus Vienna Biocenter prove how subtly plants can differentiate the various kinds of stress.

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...
