Microplastics, tiny plastic particles 5mm down to 1 nanometer in size, often breaking down further into nanoplastics, are ubiquitous environmental pollutants derived from sources like degraded plastic waste, synthetic textiles, tire wear, and cosmetics. They enter the human body primarily through ingestion (via food and water), inhalation (from air), and to a lesser extent, skin absorption. Once inside, they can circulate via the bloodstream and accumulate in various organs and tissues. Presence and Accumulation in the Body . Research has detected microplastics in numerous human tissues, including blood, lungs, liver, kidneys, spleen, placenta, breast milk, and even bone. A 2025 postmortem study analyzed tissues from decedents and found concentrations ranging from hundreds to thousands of micrograms per gram in organs like the liver and kidneys. Polyethylene (PE) was the most common type identified, often appearing as nanoscale shards or flakes. Inhalation appears ...
A lbert Einstein and David Hilbert each chased the theory of General Relativity on their own paths. Einstein leaned on physical intuition and imaginative thought experiments, whereas Hilbert dove into precise mathematics and sophisticated geometry. In the end, Einstein arrived at the complete theory first, and Hilbert graciously acknowledged it. But this isn't a story about physics—it's about the way we think. Whether you're a banking CEO, a CPA, or running a manufacturing company, you've mastered your field. You grasp all the technical and analytical nuances of your work. So, when pondering an event that impacts your business, you don't pull out textbooks for a deep dive. Instead, you rely on your intuition to guide you. That's because you've absorbed all that knowledge so thoroughly that it's woven into your mindset, emerging naturally as intuition. The same held true for Einstein, Hilbert, and even Henri Poincaré, who also tackled General Relat...
