Colorimetric chiral recognition by a molecular sensor
Article Abstract:
A system of molecular sensors, in which two chromophores are affected by chiral substrate binding to varying extents, produces a powerful chromogenic system for chiral recognition. Chiral substrate recognition produces proton transfer and conformational changes in a receptor based on chiral calixarene. This produces spectral shifts in the two chromophores linked to the binding cavity of the calixarene. A difference in the spectral shifts in the chromophores results in color change accompanying the binding, which enables visual discrimination between the enantiomers.

Kin recognition in honeybees
Article Abstract:
Cuticle hydrocarbon profiles of worker honeybees differ significantly between subfamilies, suggesting that these profiles may play a role in kin recognition and allow bees to act nepotistically. Cuticle hydrocarbons possess the necessary prerequisites of sufficient variability and genetic determinism for use as labels for subfamily recognition.
