A team of scientists has created a new guide to advance standards for collecting and cataloging DNA from marine species, ...

A creature can shed anything from dead skin cells to mucus to faeces as it moves through its surroundings. The DNA in this organic matter is known as environmental DNA (eDNA). If someone tested a ...

The researchers on Viking's Octantis cruise ship are studying environmental DNA (eDNA) — bits of genetic material that float in the water, drift through the air, or linger in the soil.

Researchers in the UK have successfully isolated airborne mammalian DNA, showing that in air, just as in water, animals leave behind invisible but useful traces of themselves that scientists can ...

Mobile DNA elements, such as Insertion Sequence (IS) elements, transposons, integrative elements (e.g. integrative islands), ...

Mariella is an assistant editor at The Scientist. She has a background in neuroscience, and her work has appeared in Drug Discovery News and Massive Science.

Internal and external environmental factors, like gender and temperature, influence gene expression. Sex-limited traits are also autosomal. Unlike sex-influenced traits, whose expression differs ...

Because DNA replication errors or environmental agents that damage DNA can introduce mutations if not corrected, multiple cellular DNA repair mechanisms exist to remove damaged regions of ...

Our research provides a case study for how ancient environmental DNA can contribute towards this understanding.

The patents cover proprietary progressions in DNA adduct detection and analysis, which can evaluate genomic instability that occurred due to environmental toxins and metabolic byproducts.
