In this study, researchers described the previously little-known flower beetle Protaetia (Potosia) jelineki from north-eastern Turkey. They provided detailed descriptions and illustrations of the beetle's larvae and pupae, as well as information on the variation seen in the adult population. The researchers also discussed the identity of a previously known syntype, and introduced a new character for diagnostic purposes. The natural history of P. jelineki was also documented, including its association with flowering plants and activity periods. This study provides valuable contributions to the taxonomic knowledge of P. jelineki.
A new species of spider, Harpactea popovi, has been discovered in beech forest habitats in Southeastern Bulgaria.

Illustrations and photographs of the new species are provided.
Researchers investigated the effects of a botanical drug derived from three plants on schizophrenia-like behaviors induced by MK-801. The drug has been used to treat rheumatoid arthritis in Korea. The study found that the herbal complex extract improved cognitive function and reduced the symptoms of schizophrenia-like behaviors in mice. These results suggest that the botanical drug could potentially be used to treat schizophrenia in humans.
