In 2005 researchers at the University of Gothenburg and Stockholm University discovered a new species of seaweed. The species, which was named Fucus radicans, evolved from a bladder wrack (Fucus vesiculosus) ancestor from the Baltic Sea.
Detailed studies of Fucus radicans show that, from an evolutionary perspective, it was formed extremely rapidly: the species was formed less than 2,500 years ago, and probably as recently as about 400 years ago. This discovery is one of few examples of extremely rapid species formation. The results also show that new species can also be formed in the relatively young and species-poor Baltic Sea.
"We are now working on understanding how the species was formed. Fucus radicans is very common in the Baltic's Gulf of Bothnia, and we want to understand its significance to the ecosystem," said Ricardo Pereyra, a researcher at the University of Gothenburg's Department of Marine Ecology.
The discovery is being published in an article in the journal BMC Evolutionary Biology: http://www.biomedcentral.com/1471-2148/9/70/abstractContact:

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...
