Walking on a rocky intertidal shore you will see a fascinating landscape often dominated by large algae of different sorts. It is a beautiful environment full of fantastic discoveries including the enigmatic seaweeds. Despite the absence of flowers, colour is not lacking among the algae; the normal colour of grass and herbs is here often replaced with more red and brown than green.
The red colour is provided by the red seaweeds. The red seaweeds are the evolutionary sister group to all green plants and algae and had common ancestor approximately 1,500 million years ago. Compared to the green plants we know very little of red algae, even though according to the secondary endosymbiosis theory, their photosynthetic machinery has been adopted by a majority of the phytoplankton, including diatoms and dinoflagellates.
To learn more about these enigmatic plants biologist Stefan Rensing from the University of Marburg together with an international consortium led by the Station Biologique de Roscoff has analyzed the genome of Chondrus crispus, or Irish moss. The consortium is led by the Station Biologique de Roscoff in Brittany, France, belonging to Le Centre national de la recherche scientifique (CNRS) and Université Pierre et Marie Curie (UPMC).

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...
