Imagine discovering that an animal species you thought had gone extinct was still living without even laying eyes on it. Such was the case with the Brazilian frog species Megaelosia bocainensis, whose complete disappearance in 1968 led scientists to believe it had become extinct. But through a novel genetic detection technique, it was rediscovered in 2020.
Such discoveries are now possible, thanks to a new approach that recovers and reads the trace amounts of DNA released into the environment by animals. It’s called environmental DNA, or eDNA and it takes advantage of the fact that every animal sheds DNA into its environment via skin, hair, scales, feces or bodily fluids, as it moves through the world.

CINCINNATI (CN) The constitutionality of two Tennessee abortion regulations was debated before an appeals panel on Thursday, as the state seeks to reimpose a ban on selective abortions and those performed after the detection of a fetal heartbeat.
The restrictions, passed as part of House Bill 2263 in June 2020 and signed into law a month later, impose criminal penalties on doctors who perform abortions when the woman seeks the procedure based on the unborn child’s gender or race, or when the fetus has been diagnosed with Down syndrome. Physicians also faced Class C felony charges for performing abortions after the detection of a fetal heartbeat under the statute.
