Measuring Underwater Noise: Protecting Marine Life and Powering Ireland
Introduction: A quiet revolution beneath the waves As Ireland advances its offshore wind ambitions, researchers are turning a critical eye to an often overlooked factor: underwater noise. The hum and crash of marine traffic, pile-driving during turbine installation, and ongoing operational sounds from turbines all contribute to a complex acoustic environment. Measuring underwater noise is…

Ancient Parasites Rewrote History: 480-Million-Year-Old Fossil Reveals Early Parasitism
Groundbreaking fossil reshapes our view of parasitism A remarkable fossil finding from Morocco is rewriting a chapter in the story of life on Earth. Researchers have identified parasitic worms burrowing into mollusc shells in the Fezouata Shale, dating to roughly 480 million years ago. This discovery pushes back the known onset of parasitism by about…
