Scientists make progress toward understanding mysteries surrounding animals that live in the dark recesses of the oceans
The largest habitats on Earth are located in the vast, dark plains at the bottom of the ocean. Yet because of their remoteness, many aspects of this mostly unexplored world remain mysterious. New research led by Scripps Institution of Oceanography at the University of California, San Diego, has produced a rare insight into animal populations in the deep sea.
In first-of-its-kind research published in the March issue of the journal Ecology, David Bailey, Henry Ruhl and Ken Smith of Scripps analyzed fish and other marine animals over a 15-year period in the deep sea of the eastern North Pacific Ocean. At the site, the source of one of the longest time-series studies of any abyssal area in the world, the scientists found a threefold increase in fish abundance, an upsurge that appears to have been driven by an increase in the food available to the animals.

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...
