Microplastic Inhalation and Metabolic Shifts Age the Global Brain

Austere editorial image representing the Pressure Systems edition “Microplastic Inhalation and Metabolic Shifts Age the Global Brain”.

As researchers refine detection methods for microplastics in human lungs and blood, a parallel metabolic crisis is accelerating cognitive decline across a quarter of the adult population. These biological breaches, tracked through new viral catalogues and rigorous lab recalibrations, reveal how industrial pollutants and systemic health failures are fundamentally reprogramming human physiology and neurological resilience.

    How much microplastic are we actually breathing in? Here’s what we do and still don’t know

    The Conversation2026-07-14

    You’ve already inhaled thousands of microscopic particles today. Some will be dust, pollen or soot, and some are plastic. Microplastics – tiny fragments shed from clothes, tyres or packaging – have been found pretty much everywhere. They’re in oceans, soils, wildlife, remote mountaintops and deep-se…

    One in four adults has metabolic syndrome – and it may be ageing their brains

    The Conversation2026-07-14

    Metabolic syndrome is linked to higher risk of many health problems – including those that affect the brain. Belight/ Shutterstock An estimated one in four adults worldwide has metabolic syndrome. While metabolic syndrome is most often thought of as a warning sign that diabetes or cardiovascular dis…

    New virus catalogue reveals which pathogens pose the greatest threat

    The Conversation2026-07-06

    In a typical year, scientists discover two or three viruses that have never been seen in people before. The number fluctuates, but the trend has been fairly steady since the 1960s. Most of these viruses attract little attention, and my colleagues and I have often had to search through old medical pa…
