Ecology and evolution of pyrazines in insects
Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

InfoMat, Volume 8, Issue 8, August 2026.We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

A Process‐Based Theory of Fishing
Natural Resource Modeling, Volume 39, Issue 3, August 2026.ABSTRACT The processes that lead to the capture of marine organisms in fishing gear are inherently complex, arising from interactions between the deployment of fishing effort, gear efficiency, and species‐specific demography and behaviour. A mechanistic understanding of these processes provides a principled basis for developing management approaches ...

Demonstration of melatonin in amphibia
Biosystems, 1967 The presence of melatonin in the amphibian epiphysis has been ascertained earlier by several indirect methods, demonstrating the synthesizing enzyme or precursors of the compound. This communication describes the presence of melatonin in amphibian brain in a direct way, using dextran gel chromatography as a separation method.
