When most people think about pollution, they picture plastic bottles floating in rivers or oil washing onto beaches. Yet some of the most powerful pollutants are completely invisible. Among the most concerning are oestrogenic compounds, chemicals capable of mimicking or interfering with the natural hormone oestrogen. These substances enter waterways through wastewater treatment works, agricultural runoff, pharmaceutical waste, industrial discharges and even everyday household products. For fish living in rivers, estuaries and coastal waters, particularly species that migrate between freshwater and the sea, exposure to these hormone-like chemicals can disrupt reproduction, alter development and potentially threaten long-term population health. What Are Environmental Oestrogens? Environmental oestrogens, often called xenoestrogens, are compounds that imitate the biological activity of natural oestrogen hormones. Common sources include: Synthetic hormones from contraceptive medications Pharmaceutical compounds excreted by humans and livestock Industrial chemicals Certain pesticides Plastic-associated compounds such as bisphenols Wastewater treatment plant effluent Even at extremely low concentrations, some of these substances can trigger biological responses because hormones naturally operate at minute levels within living organisms. Why Estuaries Are...

For centuries, mushrooms have been associated with witches, fairies, poisonings, magic potions and mysterious illnesses. Some of those stories contain a grain of truth. Many do not. Let's separate fungal fact from fungal fiction and explore some of the most persistent mushroom myths still circulating today. Why Are There So Many Mushroom Myths? Before modern science, fungi were incredibly difficult to explain. Mushrooms seemed to appear overnight. Strange circular formations suddenly emerged in fields. Some species looked colourful and inviting while others caused serious illness. Without an understanding of spores, DNA or underground fungal networks, folklore filled the gaps. Today, mycology allows us to understand fungi far more accurately, but many old beliefs continue to persist. Many common mushroom myths originated long before scientists understood fungal biology. Myth 1: All Toadstools Are Poisonous This is perhaps Britain's most persistent mushroom myth. The word toadstool has no scientific meaning whatsoever. Biologists don't classify fungi into mushrooms and toadstools. Scientifically speaking, they're simply mushrooms. Historically, people often used: Mushroom = edible fungus Toadstool = poisonous fungus Unfortunately, nature...

When most people think of fungi, they imagine mushrooms poking through woodland soil after a rainy day. But mushrooms are merely the tip of the iceberg. The real fungus is usually hidden underground, quietly spreading beneath forests, gardens and fields. This secret world is known as mycelium, and it may be one of the most important biological networks on Earth. Once you understand mycelium, you'll never look at a mushroom the same way again. The Mushroom Is Just the Fruit Imagine walking into an apple orchard and deciding that the apples are the entire tree. It sounds ridiculous, yet that's effectively what most people do with mushrooms. A mushroom is simply a reproductive structure designed to release spores and help the fungus spread. The main organism exists elsewhere, often completely hidden from view. The mushroom is only the visible fruiting body. Most of the fungus exists underground as an extensive mycelial network. That hidden body is mycelium. Made from millions of microscopic filaments called hyphae, mycelium forms intricate web-like networks...
