An international team of researchers has announced the discovery of new fossils from the highlands of Ethiopia. The fossils fill a long-standing gap in scientists understanding of the evolution of African mammals. The results are reported in this weeks issue of the journal Nature.

The team is composed of researchers from several U.S. universities, including the University of Texas, Washington University, and the University of Michigan, as well as Addis Ababa University and the National Museum, both in Ethiopia. The project is supported by the National Science Foundation (NSF), the National Geographic Society, the Leakey Foundation, and the Ethiopian Ministry of Culture.
"The work of this team continues to reveal the extremely rich fossil record encased in East Africas rocks," says Rich Lane, program director in NSFs division of earth sciences, which funded the research. "It also sheds light on the role pre-modern animals played in establishing the worldwide distribution of mammals today."

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...
