Insect Conservation and Diversity, Volume 18, Issue 4, Page 593-603, July 2025.The increase in urban lands and the vegetation loss implies changes in the colour of the background which in turn could cause changes in the coloration of individuals. We measured changes in body lightness of damselflies through 19 sites in Central Mexico, with a different degree of urbanisation and a different percentage of native vegetation. We found

A single gene (yes) controls pigmentation of eyes and scales in Heliothis virescens
Journal of Insect Science, 2001 A yellow-eyed mutant was discovered in a strain of Heliothis virescens, the tobacco budworm, that already exhibited a mutation for yellow scale, y. We investigated the inheritance of these visible mutations as candidate markers for transgenesis.

Prediction of Fragmentation Pathway of Natural Products, Antibiotics, and Pesticides by ChemFrag
Journal of Mass Spectrometry, Volume 60, Issue 5, May 2025.ABSTRACT Because the manual interpretation of ESI‐MSn fragmentation spectra is time‐consuming and usually requires expert knowledge, automated annotation is often sought. The fragmentation software ChemFrag enables the annotation of MSn spectra by combining a rule‐based fragmentation and a semiempirical quantum chemical approach.

Photo-reduction of Pteridines [PDF]
Nature, 1956 WHEN a solution of 7-hydroxypteridine1 was spotted on a sheet of Whatman No. 1 filter paper, irradiated with ultra-violet light (principally 254 mµ) for 5 min., and developed (by ascending chromatography) in various solvents, two spots appeared. One of these was identical with the starting material (unirradiated material was used as a control on the ...
