New DNA tech helps track Amazonian manatees, a shy vulnerable species, by analyzing traces of their genetic material in water samples. Detection rates were much higher in areas with less human ...

Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been ...

The ability to extract trace bits of DNA from soil, water, and even air is revolutionizing science. Are there pitfalls? By Peter Andrey Smith/Undark Published Feb 14, 2024 8:06 AM EST This article was ...

Salmon lie on the deck of a commercial fishing boat. With refinements to eDNA tracking methods, researchers can now collect data about what fish were present in an area up to two days after the fish ...

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning ...

Air samples collected at pollution monitoring stations could provide a treasure trove of data on plant and animal life thanks to new environmental DNA methods. Environmental DNA (eDNA) comes from shed ...

Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and ...

Environmental DNA (eDNA) techniques have emerged as a cost-effective and non-invasive strategy for monitoring the distribution of endangered aquatic species. Despite their numerous advantages, ...

Patrick Omeja was supported by the International Development Research Centre. The world is losing animals at an alarming rate due to habitat degradation, climate change and illegal human activities in ...

PCR genetic analysis has been in the spotlight since COVID-19, but light is now further facilitating PCR-free methods. Osaka Metropolitan University scientists have developed a light-induced DNA ...
