A new, rare fossil of a prehistoric sea creature bearing eyes like "twin towers" sheds light on how it lived more than 395 million years ago, says a University of Alberta researcher.
Dr. Brian Chatterton, one of the worlds leading experts on trilobites and a professor in the U of As Faculty of Science, reports on the discovery of the only known complete specimen of a particular trilobite in this weeks edition of the prestigious scientific journal Science.
Trilobites were among the most active animals in the sea--they ran around the sea floor and occasionally burrowed in the sediment or swam around. They had eyes similar to those of their distant relatives, the insects, but they also had antennae, making it possible to see and touch the world around them.

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...
