What questions will it answer; what opportunities will it offer?
History doesnt record the moment when fully conscious humans asked the first question. The incessant push of human curiosity has nevertheless changed the world. Even so, despite the seemingly inexorable march of science and technology into the current century, questions dont seem in short supply. Gwyn Williams, basic research program manager for Jefferson Labs Free-Electron Laser (FEL), suspects some important answers may be forthcoming as a result of the FEL upgrade currently underway.
"The FEL is such a powerful light source that it induces completely new phenomena in materials," Williams says. "All kinds of unexpected properties emerge. Creating carbon nanotubes [for electronics and super-strong structures] comes as a result of exciting graphite, for instance. This upgrade gives us a window with a whole new view. Were beginning to truly understand how the world works at the level of a single atom."

In meningococci, the RNA-binding protein ProQ plays a major role. Together with RNA molecules, it regulates processes that are important for pathogenic properties of the bacteria.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding...
An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links...
Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.
