The United States Department of Energy (DOE) Joint Genome Institute (JGI) announces today the publication of a high-quality draft genome sequence of the white rot fungus, Phanerochaete chrysosporium. These are the only known microbes capable of efficiently degrading the recalcitrant aromatic plant polymer lignin, one of the most abundant natural materials on earth. White rot fungi such as Phanerochaete chrysosporium play a pivotal role in the carbon cycle--the circulation of carbon from the atmosphere into organisms and back again. They also have demonstrated the ability to remediate explosive contaminants, pesticides and toxic waste with similar chemical structures to lignin. The sequence findings are summarized in the May 2nd on-line edition of the journal Nature Biotechnology.
"Phanerochaete chrysosporium is the first basidiomycete fungus to be sequenced, providing a glimpse into the genetic diversity of fungi," says Dan Rokhsar, head of the JGI Computational Genomics Department. "Its the first of a trio of fungal genomes well be tackling that have their own unique constellation of degradative enzymes. The availability of these genomes will spur industrial and bioremediative uses for these organisms."
Basidiomycetes are represented by important agricultural species including the familiar edible white button mushroom, Agaricus bisporus, and such plant pathogens as smuts and rusts. They also comprise certain opportunistic human pathogens that can be problematic especially in immune-compromised individuals. The basidiomycetes are believed to have diverged from the ascomycetes, a classification that includes Saccharomyces cerevisiae (brewers yeast) and Neurospora (bread mold), over 500 million years ago, and to be more than a billion years removed from plants and animals.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
