Zoo air contains enough DNA to identify the animals inside

The air in a zoo is full of smells, from the fish used for feed to the manure from the grazing herbivores, but now we know it is also full of DNA from the animals living there. In the journal Current Biology on January 6th, ...

MetaPlatanus improves metagenome assembly

Metagenomics often involves sequencing DNA samples that can only be described as "tricky." Such DNA shows high heterogeneity, which can cause interspecies misassemblies. These misassemblies threaten the very purpose of metagenome ...

Mountaintop mining causes 40 percent loss of aquatic biodiversity

Trickling down over rocks, surrounded by wildflowers and ferns, Appalachian mountain streams are chock-full of life. They hold some of the world's greatest diversity of freshwater animals, including many species that can't ...

New breakthrough in research using insect exoskeletons

Research into insect species can benefit from genetic studies. However, genetic samples can often be difficult to collect in a non-invasive manner, especially when the insects are only found in a particular location or are ...
