We report on random lasing action in zinc oxide microparticles dispersed in organic disordered hybrid polymer. Lasing action from zinc-oxide–polymer hybrid is reported at temperature ranging from 6to250K. Coherent backscattering measurements reveal that the transport of light in the sample is diffusive and feedback for lasing is incoherent. The zinc oxide particles provide both the gain and the scattering whereas polymer matrix offers ease of material fabrication.

A checklist of earthworm species hitherto recorded from North Eastern Region (NER) of India is presented. In total, 128 species/subspecies belonging to 26 genera spread over 9 families are listed. Of these, 72 species are recognized as endemics, 18 as near endemics, 5 as native peregrines and 32 as exotics. The checklist includes literature citation to the original description, type locality, important synonyms and the state-wise distributional records for each species/subspecies.
