How we can detect pretty much anything - Hélène Morlon and Anna Papadopoulou

Explore how scientists use environmental DNA (eDNA) in a technique called DNA metabarcoding to find and track species.

--

Scientists have been staking out a forest in Montana for an animal that’s notoriously tricky to find. Camera traps haven’t offered definitive evidence, and experts can’t identify its tracks with certainty. But within the past decades, researchers have developed methods that can detect even the most elusive species. So how does it work? Hélène Morlon & Anna Papadopoulou dig into DNA metabarcoding.

Lesson by Hélène Morlon and Anna Papadopoulou, directed by Blok Magnaye.

"DNA neither cares nor knows. DNA just is. And we dance to its music" - The most random quote I've seen so far still these animations are pure gold...

"The world is covered in DNA."

*looks around me suspiciously* That's what I was afraid of.

Thank you for featuring the newly discovered Binburrum zapdos. ❤️

[shreeyamittal]

Love how you explained such a complex topic! As always, dug the animations too!

[wingsofliberty]

What a beautiful episode . Beautiful animation, sounds and knowledge .

[intellizebrainfolio]

The advancement in science is always fascinating. Thanks for sharing🙂

Ted: We can (now) track anything.
Me: Great ... can you find my keys?

[randallkelley]

I thought this was proof for YETI. Dang...

[thanurirajapakshe]

Metabarcoding is vey important to find and track species, what a clear explaination.

[ronaldfigueroa]

It’s amazing how you guys dive into this complex informations, but DNA is so huge to include and understand for just one video but it was astonishing

[altinmares]

Ted Ed please post more videos about
-Aristotle teaching Alexander the Great
-Tengrism
-Presocratic philosophers
-Islamic Golden Age (discoveries, achievements)
-Plato wisdom and teachings

Imagine, Vsauce, Kurz, Ted, Lemmino, Simple history as your professors.

Neat technology. A faster way to get an idea of what lives where should provide the public and politicians with a great tool to save or improve bio diversity everywhere. Whether we do anything with that information is a completely different question.

[madhavhans]

thank you for provide soo good/important videos and educational video for us and with such good animations. Really Thank You.

[Amr-H]

We appreciate that this channel always brings such interesting facts to us

Me: I just want to detect the presence of my phone in my pocket

I'm really amazed how far our technology, research and archiving have improved in just a few decades. However, I don't think this will save the environment as long as humans continue destroying it.

This voice is soo beautiful it calms my heart and calmly asks me to sleep😴
