- Redox Signalling Explained: How Cells Use Reactive Oxygen as a Message
Redox signalling at a glance What it is: cells using small, controlled amounts of reactive oxygen and related molecules to pass messages The main messenger: hydrogen peroxide, working at very low concentrations How messages are read: reversible chemical changes to sulphur-containing cysteine sites on proteins A famous example: nitric oxide, whose signalling role in blood … Read more - The Biology of Ageing Explained: The Twelve Hallmarks and What the Research Shows
The biology of ageing at a glance The framework: twelve hallmarks of ageing, set out by leading researchers in 2013 and updated in 2023 The common thread: damage builds up faster than cells can repair it, and the body’s responses gradually become part of the problem Genes versus life: recent large studies suggest genes explain … Read more - Why Some People Handle Toxins Better Than Others: The Genetic Lottery of Oxidative Stress
Genetic variations inherited before birth significantly shape how your cells defend against oxidative damage from toxins. Some people mount stronger, faster antioxidant responses due to inherited genetic differences, while others produce weaker defences to the same exposures. - Muscle Memory: How Oxidative Stress Triggers Cellular Learning
Exercise creates oxidative stress that acts as a signal, not just damage. Your muscle cells respond by encoding these stress signals into lasting cellular changes that persist even after you stop training. - How Copper Nanoparticles Hijack Mitochondrial Assembly and Stress Responses
Copper nanoparticles penetrate mitochondria and disrupt the assembly of respiratory chain complexes, triggering cellular stress responses. Research reveals that nanomaterials hijack ancient defence systems cells evolved to handle very different threats.
