The study offers up new molecular sites as potential drug targets. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22693&type=Feature&page=1 Recent developments in X-ray spectroscopy in the last decade are reviewed, with special emphasis on the the strong natural connection between X-ray spectroscopy and materials science. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22620&type=Feature&page=1 US researchers have used an X-ray technique to solve the molecular structure of a key portion of a cellular receptor implicated in Alzheimer's, Parkinson's, and other serious illnesses. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22560&type=Feature&page=1 X-Ray fluorescence microscopy reveals details of the role of selenium in spermatogenesis. The new research lends support to earlier studies and anecdotal evidence regarding this otherwise difficult to image element. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22535&type=Feature&page=1 A Monte Carlo method was developed and combined with micro-beam X-ray fluorescence for the determination of the chemical composition of individual particles and was applied to a collection of glass micro-spheres, http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22505&type=Feature&page=1 <p>The board of directors of Thermo Fisher Scientific Inc. has appointed Marc N. Casper president, chief executive officer and a director of the company, effective 15 October 2009. Casper currently serves as executive vice president and chief operating officer.</p> <p>This announcement follows the decision of Marijn E. Dekkers to resign as president, chief executive officer and a member of the board, in order to become chief executive officer of Bayer AG.</p> <p><a href="http://www.separationsnow.com/coi/cda/detail.cda?id=22504&type=Feature&chId=0&page=1"><font color="red">Watch our video interview >>></font></a></p> http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22454&type=Feature&page=1 Nanoparticles can self-assemble into quasicrystalline structures, according to researchers in the USA. The newly discovery structures could provide useful insights into how such non-periodic, and yet ordered, that lie half way between amorphous solids and regular crystals can arise. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22376&type=Feature&page=1 Three scientists, one in the UK, one in Israel, the other in the US, are the joint recipients of the 2009 Nobel Prize for Chemistry "for studies of the structure and function of the ribosome". http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22356&type=Feature&page=1 The intraspecific and intraindividual variations in the sizes of the three semicircular canals in the right and left temporal bones of the short-tailed shrew were measured on a high-resolution X-ray computed tomography system. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=8&id=22275&type=Feature&page=1 New clues as to the virulence of the potentially lethal bacterium Escherichia coli O157:H7 has emerged from structural and functional relationship studies of its autotransport and proteolytic EspP proteins.
