Russian Science: Waking From Hibernation
Daniel Clery
<jats:p>Russian science has moved beyond survival mode and is trying to recapture its research glory. But as the government backs universities and applied research, what does the future hold for the Russian Academy of Sciences?</jats:p>
Palabras clave: Multidisciplinary.
Pp. 1036-1042
University Research Should Compete With Russian Academy, Science Minister Argues
Daniel Clery
<jats:p> Minister of Education and Science Andrei Fursenko met with <jats:italic>Science</jats:italic> at the ministry's imposing Tverskaya Street headquarters in September to discuss how Russia plans to reinvigorate its research base. </jats:p>

Uncertain Future for Academy's Biology Experiment
Daniel Clery
<jats:p>Ask anyone familiar with the Russian Academy of Sciences how the organization can be reformed so that it funds the best researchers, rather than those with the best connections, and the discussion quickly turns to the efforts of Georgii Georgiev, who runs the academy's Molecular and Cell Biology program.</jats:p>

Comment on “Single-Crystal X-ray Structure of 1,3-Dimethylcyclobutadiene by Confinement in a Crystalline Matrixâ€
David Scheschkewitz
<jats:p> Legrand <jats:italic>et al</jats:italic> . (Reports, 16 July 2010, p. 299) reported on the photolytic reaction of an α-pyrone confined in a crystalline matrix. Their structural analysis invoked four products: activated precursor, isomeric Dewar β-lactone, and square and rectangular isomers of 1,3-dimethylcyclobutadiene. The reported x-ray data, however, suggest that all observed structures correspond to only one distinct species, the Dewar β-lactone. </jats:p>

Response to Comments on “Single-Crystal X-ray Structure of 1,3-Dimethylcyclobutadiene by Confinement in a Crystalline Matrixâ€
Yves-Marie Legrand; Arie van der Lee; Mihail Barboiu
<jats:p> Scheschkewitz and Alabugin <jats:italic>et al</jats:italic> . suggest that photolysis under confinement in a crystalline matrix of 4,6-dimethyl-α-pyrone does not yield the crystal structure of 1,3-dimethylcyclobutadiene (Me <jats:sub>2</jats:sub> CBD) as we reported, but rather that of a 4,6-dimethyl-β-lactone intermediate. We provide arguments that the square-planar Me <jats:sub>2</jats:sub> CBD <jats:sup>S</jats:sup> <jats:bold>/</jats:bold> CO <jats:sub>2</jats:sub> complex and the rectangular-bent Me <jats:sub>2</jats:sub> CBD <jats:sup>R</jats:sup> molecule are stabilized under confinement by the guanidinium-sulfonate-calixarene host matrix used in our study. </jats:p>
