''Nuclear magnetic resonance (NMR) is one of the best tools for gaining insight into the structure and dynamics of molecules because nuclei in atoms within molecules will behave differently in a variety of chemical environments. Nuclei can be thought of as ...'

''Ultra-short X-ray beams produced at the University of Michigan could one day serve as more sensitive medical diagnostic tools, and they could work like strobe lights to allow researchers to observe chemical reactions that happen in quadrillionths of a ...'

''For certain kinds of cancer, the most effective therapy does not use x-rays or gamma rays but beams of ions, the electrically charged cores of atoms, including hydrogen ions (protons) and heavier ions such as carbon and neon. The world's foremost ...'

''Imaging the internal dynamics of excited atoms and molecules with high spatial resolution requires fast, energetic pulses of x rays. As Matthias Hoener and colleagues from an international collaboration report in Physical Review Letters, initial results ...'

''Suited for longitudinal in vivo studies, Quantum FX provides researchers with 3D anatomical view of disease activity, tumor development, and therapeutic response over multiple time points during course of study. Speed, sensitivity, and dosage of CT ...'

''The outgoing director-general of the International Atomic Energy Agency (IAEA), Dr Mohammed ElBaradei, has praised South Africa for making 'the right choice' regarding nuclear power, by scrapping its nuclear weapons and focusing on the peaceful uses of ...'

''Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine (AAPM) meeting, which takes place from July 26 - 30 in Anaheim, CA. Ways to make the ...'

''To compare the visibility of anatomic structures in direct-detector chest radiographs acquired with different tube voltages at equal effective doses to the ...'
