Visualizing antibody-catalyzed retro-aldol-retro-Michael reactions.

We developed a visible detection system for antibody-catalyzed retro-aldol-retro-Michael reactions. Aldolase antibody 38C2 catalyzed the reaction of substrate 1 to provide 6-bromo-2-napthol that forms a visible colored azo dye with diazonium salts. This system has potential for the screening of novel catalysts.

The Retro-Hydroformylation Reaction.

Hydroformylation, a reaction that adds carbon monoxide and dihydrogen across an unsaturated carbon-carbon multiple bond, has been widely employed in the chemical industry since its discovery in 1938. In contrast, the reverse reaction, retro-hydroformylation, has seldom been studied. The retro-hydroformylation reaction of an aldehyde into an alkene and synthesis gas (a mixture of carbon monoxide...

Hot and Retro Meet Arabidopsis

Using elegant experiments, Ito et al. (2011) were able to demonstrate that a siRNA pathway is crucial to prevent transgenerational retrotransposition in plants subjected to heat-stress (Ito et al., 2011). The heat-stress treatment consisted of a double-temperature-shift stress: 24 h at 6°C followed by 24 h at 37°C. The transcription of a particular family of Ty1/copia-type retrotransposons, nam...

Nostalgia in Retro Game Design

I distinguish between two kinds of nostalgia in retro game design – restorative and reflective. The former manifests itself in ‘total restoration of monuments of the past’, while the latter ‘lingers in the dreams of another place and another time’. Restorative nostalgia is visible in the retrogaming practices, such as creation of emulators, appreciation of classic titles and remaking them for n...
