Quantum chemical interactions lie at the heart of molecular structure, reactivity and function, encompassing both covalent bonding and a diverse array of noncovalent forces. Accurate description of ...

Plants, animals and microorganisms constantly communicate through chemical signals. A research team has now shown that these signals merge in the environment to form complex "chemical landscapes" that ...

(Beyond Pesticides, September 8, 2025) Beyond Pesticides today called on Congress to require the U.S. Environmental Protection Agency (EPA) to incorporate real world science into its evaluation of ...

cases an external molecule dramatically affects cellular function. Our goal in studying any of these processes is the same: a molecule-by-molecule accounting of information transfer in biological ...

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species. The biological world is awash in chemical signals. Ants lead their nest mates to food ...

These epidemiologic patterns highlight the limitations of focusing on genetics alone. Although the Human Genome Project greatly expanded our understanding of hereditary contributions to disease, genes ...

otherwise processing primary metabolites and it is the unusual chemical that circumvents these mechanisms to cause toxicity. Secondary chemicals are by definition taxonomically restricted in ...
