Museum piece: genes show where the red squirrel went.
Museum exhibits’ genes record British forestry policies
Commercial forest planting in the north of England drew red squirrels westwards in the 1980s say UK researchers. This migration led to big changes in squirrel numbers and genetics.
The finding has implications for the protection of the endangered red squirrel (Sciurus vulgaris). Many conservationists advocate leaving ’wildlife corridors’ for animals to travel between patches of fragmenting habitat. This is the first evidence that such corridors work, says Kirsten Wolff, of the University of Newcastle upon Tyne1.

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...
