Coral reefs are vibrant ecosystems that underpin marine life, protect coastal communities, and support local economies. Yet, rising sea temperatures and pollution have destabilised these delicate environments, triggering bleaching events and escalating disease outbreaks. Recent research has revealed an innovative method for detecting coral diseases at their earliest stages, combining environmental DNA (eDNA) analysis with…

Monitoring marine ecosystems is critical to understanding environmental changes and managing human impact. Traditional biomonitoring methods, while valuable, often struggle with limitations such as species misidentification and difficulty distinguishing closely related organisms. Environmental DNA (eDNA) analysis has transformed marine monitoring by detecting traces of genetic material left behind by organisms in water and sediment. However,…

Pest outbreaks can quickly turn into major economic losses if they are not identified and managed early. One of the most challenging pests in citrus farming is the Japanese orange fly (Bactrocera tsuneonis). This pest is particularly difficult to detect because its larvae develop hidden inside mandarin oranges. Recent research exploring environmental DNA (eDNA) has…

Citrus greening disease, also known as Huanglongbing (HLB), remains one of the most pressing threats to the global citrus industry. Not only does this debilitating disease drastically reduce crop yields, but it also undermines farmers’ livelihoods and endangers the worldwide supply of citrus products. At the centre of this challenge is a tiny insect, the…

Plant–pollinator interactions represent one of the most crucial relationships in ecosystems, influencing biodiversity, reproduction, and ecosystem stability. Yet, these dynamics are often difficult to study comprehensively using traditional methods of observation. A recent study from New Zealand showcases how environmental DNA (eDNA) metabarcoding significantly enhances our understanding of these interactions, revealing intricacies that had eluded…

Contamination in urban freshwater systems by faeces poses a longstanding risk to public health, compromising water quality and the sustainability of recreational sites such as beaches and rivers. Traditional monitoring methods that measure faecal indicator bacteria, including E. coli and Enterococcus, reveal water quality status but cannot conclusively identify contamination sources. A recent study underscores…

In the ever-evolving landscape of scientific innovation, breakthrough technologies are reshaping how we understand and interact with our environment. One such advancement is the integration of CRISPR-Cas12a technology with environmental DNA (eDNA) analysis—a development poised to revolutionise ecological monitoring and public health protection. Its use in tracking marine species like the box jellyfish—a significant public…

Ticks are among the most significant vectors of diseases worldwide, and their impact is increasing as climate change drives their spread into new regions. Traditional surveillance methods, while valuable, are labour-intensive, prone to delays, and often limited to specific areas. Environmental DNA (eDNA) offers a promising alternative, allowing for more rapid and scalable detection of…

In today’s world, where freshwater scarcity is becoming an increasingly pressing issue, ensuring a reliable supply of clean drinking water is more crucial than ever. Water companies face numerous challenges, including pollution, climate change, and the rise of compounds that degrade water quality. Among these, Taste and Odour (T&O) problems have emerged as a significant…

The advent of environmental DNA (eDNA) has fundamentally transformed biodiversity monitoring, particularly within aquatic ecosystems. Traditional methods such as snorkel surveys and electrofishing, although effective, often prove labour-intensive, invasive, and disruptive to species. eDNA presents a revolutionary alternative, enabling the detection of species through DNA shed into the environment via tissues, faeces, or mucus. A…
