Geneticists at the Duke Institute for Genome Sciences and Policy (IGSP) and the University of Basel have unveiled the complete genome sequence of the pathogenic plant fungus Ashbya gossypii, which infects agricultural crops including cotton and citrus fruits in the tropics. The fungus has the smallest genome yet characterized among free-living eukaryotes. Eukaryotes are the single-celled and multicellular organisms that include fungi, plants and animals.
The team -- led by Fred Dietrich, Ph.D., of the IGSPs Center for Genome Technology, and Peter Phillipsen, Ph.D., of the University of Basel -- reported its findings online in the March 4, 2004, Science Express, the online version of the journal Science. The work was completed with the funding and collaboration of Novartis (now Syngenta) in Research Triangle Park, N.C. The researchers have no financial ties to Novartis or Syngenta.
The sequencing of the fungal genome has already shed light on the evolution of Saccharomyces cerevisiae -- the single-celled bakers yeast that scientists rely on for the study of many basic questions in cell biology. Furthermore, understanding the infectious microbes genetic instructions might allow scientists to tease out the fundamental features responsible for some fungis ability to cause disease, the researchers said.

‘Spying’ on the hidden geometry of complex networks through machine intelligence

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...
