• Resumen

  • This report from Nature points the reader to a series of articles commemorating the 50th anniversary of Watson and Crick's elucidation of DNA structure. In addition, a light-powered membrane pump for Ca2+ ions is described that can generate a membrane potential and is reminiscent of photoinduced biological proton pumps. Finally, the column covers an article on the successful generation of cold anti-hydrogen as part of the collaborative ATHENA project at CERN. Scientists are hoping that this simplest of anti-matter will allow them to test the validity of the central theorem in quantum mechanics in the near future.
