Views on wolves determined more by culture than individual encounters
Whos afraid of the big bad wolf? The survey says: it largely depends on who you are and what you do, according to a study by the Wildlife Conservation Society (WCS) and the University of Wisconsin. Published in the December issue of the journal Conservation Biology, survey results among people who live with wolves in northern Wisconsin revealed that deeply rooted social identities and occupations are more powerful predictors of their attitudes toward wolves than individual encounters, or losses of pets and livestock.
Using a mail-back survey with a pool of 535 respondents, scientists found that bear hunters were the group with the least tolerance, with approximately 74 percent of the 124 hunters in the survey in favor of reducing or eliminating Wisconsins wolf population. Attitudes among this group did not vary greatly between the perceived threat and an actual loss of hunting dogs, which sometimes fall prey to wolves. By comparison, about 44 percent of livestock producers favored reducing or eliminating wolves, and only 28.5 percent of general residents supported the same. Overall, there is moderate support for wolf recovery statewide, with only 17.4 percent indicating that wolves should be eliminated.

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...
