Characteristics of the Soil in Biofuel Crop Fields Affect Its Potential to Store Carbon
Department of Energy, Office of Science

: Most of the carbon contained in soil is in the form of organic matter. Scientists do not fully understand how variation in plant inputs, microbial communities, and soil physical and chemical attributes influence the makeup of this organic matter. A new study found that soil in switchgrass fields had more water-soluble carbon compounds than soil in corn fields, an important finding for biofuel crop selection.

Promising metallodrug candidate for tumour therapy
University of Vienna

BOLD-100/KP1339 is a ruthenium-based anticancer agent that has been decisively co-developed at the University of Vienna and which has shown promising results in clinical trials in cancer patients. However, the mode of action of this metal compound has not yet been fully elucidated. Researchers from the University of Vienna and the Medical University of Vienna have now been able to demonstrate that BOLD-100 binds to ribosomal proteins in tumour cells. The study now published with a cover in "Angewandte Chemie" can support a more targeted application of BOLD-100 as tumour-inhibiting active agent.

John Chaput can store the Declaration of Independence in a single molecule
University of California, Irvine

Just how much space would you need to store all of the world’s data? A building? A block? A city? The amount of global data is estimated to be around 44 zettabytes. A 15-million-square-foot warehouse can hold 1 billion gigabytes, or .001 zettabyte. So you would need 44,000 such warehouses – which would cover nearly the entire state of West Virginia.
