Europe avoids moratorium

Myelin Avoids the JAM

In this issue of Neuron, Redmond et al. (2016) identify junction adhesion molecule 2 (JAM2) as an inhibitor of somatodendritic myelination in spinal cord neurons, thereby elucidating how myelin forms on axons but avoids dendrites and cell bodies.

Harmful moratorium on stem cell research.

Light Avoids Anderson Localization

The confinement of waves in a disordered medium—Anderson localization [1]—has been observed for electromagnetic [2, 3] and acoustic [4] waves in disordered dielectric structures, and for electron waves in condensed matter. Anderson localization arises as a result of the constructive interference between waves that follow time reversed paths as they loop back to a point as a result of scattering...

Proposed Moratorium on Changes to Network Protocol

Bill Crowther’s RFC No. 67 raised a much more fundamental issue than the question of marking. Any change to presently established protocol is going to involve changes in the hardware/software development efforts that have, in some instances, been going on for over 6 months. In the case of Multics, this effort has yielded programs either complete or in the advanced debugging stages. This is no d...

The H5N1 Moratorium Controversy and Debate

The pause in gain-of-function experiments involving highly pathogenic avian influenza virus to dissect mechanisms of mammalian transmission and virulence is a historic moment for science. The scientific community and the greater society that it serves are currently engaged in a vigorous debate on whether and how to carry out experiments that could provide essential information for preparedness ...
