But sometimes, the penis grows back and they eventually mate.
How is that regulated? And can we maybe even induce the penis growth? The applications of this research are sky-high.

There can’t be anything cooler, or? Well, there is…
Altough being hermaphrodites, not every slug have penis. And some of them are doing just fine without a it. They reproduce by themselves, not worrying about finding a partner.

Slugs can also regenerate – and quite a lot.
You can cut their head off and it grows back, with all the nerves as well!

In mammals, the war between invasive elements and genome guards happens only in germline. But in slugs it is ongoing in the body as well.
What if we turn the protection system off and let the invasion spread? How will slugs cope with that?

Molluscs have messy genomes with lots of repeats and they have to fight back.
piRNA pathway guards the genome against invasive elements (such as transposons). It targets and silences them, so they cannot spread further.

Slugs are occupying an unexplored part of the phylogenetic tree.
They haven’t enjoyed much attention from scientists, yet they hide many secrets that are just starting to be uncovered.
Studying them is like setting on a voyage to explore new lands overseas.

If it´s a new complicated topic, no more than an hour straight. And I always appreciate when the lecturer changes the pace of the talk and incorporates "checkpoints", so that when I zone out for a moment, I have a chance to chatch up again.
