A phenothiazine derivative was found to exhibit multicolour- and high-colour-contrast switching in response to force and acid vapour by introducing an asymmetric D–π–A–π–D structure.

Fifty-two Neolithic tombs (dolmens) were grouped into megalithic stations that are mostly located on lithotecto from which the building rocks were removed. In six dolmens, there were no clues found to explain the presence of allochthonous stones, except perhaps in one of them, where rocks were selected to cause colour contrast. The morphology of the slabs, of chambers and corridors, showed no evidence of carving. The angularity of the tumulus blocks indicates that some were collected from the surface and others were manually fragmented. The identification of the construction materials in Neolithic dolmens with elemental geological features provides information on the building process, adding valorisation to the prehistoric monuments and enabling their reconstruction.

Honeybees response to landing guide located on flowers of Smithia hirsuta Dalzell, an endemic herb of India is studied. The bees perceive the colour contrast as landing guide which serve as a map to the concealed floral reward, the nectar. Hence they associate these with nectar and forage precision with maximum energy conservation. Detailed taxonomy of S. hirsuta Dalzell is also provided.
