A Year On, the H5N1 Debate Remains Infectious, With No End in Sight

David Malakoff

<jats:p>Two controversial studies that showed how to make the H5N1 avian influenza virus transmissible among mammals have left scientists wondering which kinds of studies are worth the risk and how potentially dangerous results should be reviewed and safely communicated to the public and public health experts.</jats:p>

Response to Comment on “The Local Structure of Amorphous Silicon”

M. M. J. Treacy; K. B. Borisenko

<jats:p>The averaged diffraction data alone cannot distinguish between models with different heterogeneous structures at length scales of about 2 nanometers, even when using high-resolution data. Although our approach to calculating diffraction intensities from the model differs from that of Roorda and Lewis, paracrystallinity in amorphous silicon is undeniably evident in the raw experimental fluctuation electron microscopy data.</jats:p>

Comment on “The Local Structure of Amorphous Silicon”

Sjoerd Roorda; Laurent J. Lewis

<jats:p>Treacy and Borisenko (Reports, 24 February 2012, p. 950) argue from reverse Monte Carlo modeling of electron diffraction and fluctuation electron microscopy data that amorphous silicon is paracrystalline and not described by a continuous random network. However, their models disagree with high-resolution x-ray measurements and other evidence, whereas the agreement with fluctuation electron microscopy is at best qualitative.</jats:p>
