The most common process for making hydrogen peroxide begins with a highly toxic, flammable working solution that is combined with hydrogen, filtered, combined with oxygen, mixed in water, and then concentrated to extremely high levels for shipping.  A way of making organic polymers from the fragrant molecules in conifers and fruit trees has been developed by scientists at the University of Birmingham.  The development of mass spectrometry (MS) methods-those which define the chemical composition of cells-represent a further milestone for research in the field of cell biology.  These reactions lead to a host of activities in plants, including converting primary metabolites like phenylalanine and tyrosine into vital specialized molecules called flavonoids.  Researchers at the UPV/EHU-University of the Basque Country have developed a biomedical device for cell immune-isolation (microcapsules) with luminescence for in vivo tracking.  Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans-and has guided the development of precision drugs to combat diseases such as cancer and AIDS.  How did life arise on Earth? Rutgers researchers have found among the first and perhaps only hard evidence that simple protein catalysts-essential for cells, the building blocks of life, to function-may have existed when life began.  A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.  Bacterial systems are some of the simplest and most effective platforms for the expression of recombinant proteins.
