Supergene research solves the mystery of tiny ant queens

An ant colony is sustained through complex social dynamics, with each member—the queen, males and workers (sterile females)—contributing to the greater community. Some species add complexity to this dynamic with the addition ...

Identifying tropane alkaloid types in Hyoscyamus niger L.

Researchers conducted a study on tropane alkaloids (TAs), crucial natural compounds found abundantly in various plant families. TAs, often toxins, include major ones like L-hyoscyamine, atropine, and scopolamine, each with ...

Researchers discover key gene for toxic alkaloid in barley

All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley, one of the world's most widely-grown cereals. Gramine provides protection against herbivorous ...

Bacterial RNAs have shorter lifetimes than expected

The decay of ribonucleic acid (RNA) is a crucial mechanism for controlling gene expression in response to environmental stresses. Researchers from the Helmholtz Institute for RNA-based Infection Research (HIRI) and the Julius-Maximilians-Universität ...
