Reply to comment by linkdude212 in A male-killing gene encoded by a symbiotic virus of Drosophila by eniteris
I think that a lot of the framing is being lifted from the bacterial endosymbionts of insects, which can also cause male killing. The bacteria is only transferred through the egg, so killing males doesn't harm the bacteria (and may benefit if the females have more resources due to the lack of males).
(these bacteria can also help the insect gain various other benefits)
But as a virus, this explanation doesn't make as much sense (since it should be easier to transfer in the sperm than a whole bacteria), and to my knowledge no benefits have yet been observed. But it's borrowing from the same framework, so I think that's why they called it a symbiont.
edit: Also technically speaking, symbiote refers to any long-term close interaction. Mutualistic symbiosis is the classic codependent relationship, but you also have commensal and parasitic symbiotic relationships as well.

Also of interest: the virus is in the family Partitiviridae, has four genes (one on each "chromosome"), and each "chromosome" is packaged into a separate viral particle.

Reply to Study finds “forever chemicals” disrupt key biological processes. The disruption of these biological processes is connected to an increased risk of a very broad range of diseases, including developmental disorders, cardiovascular disease, metabolic disease and many types of cancer. by Wagamaga
This study shows association, not causation.
Also their participant group is specifically overweight/obese young adults. Would be interesting to see obesity vs. PFAS blood concentrations, since processed food packaging seems to contain PFAS.

The paper shows that it turns into CO2.

Multicellularity is a spectrum with no hard cutoff, unless you would like to personally provide one?

It's not just filamentous colonies or biofilms, but the differentiation into different life stages and the formation of what appears to be a fruiting body that's interesting. Also reacts to being submerged in water.
And it's a novel multicellular prokaryote, not novel multicellularity in general.

There's another species of eel in Britain, but yes, jellied eels are mostly made from silver eels, and they're critically endangered.
The European Eel/glass eel/yellow eel/silver eel migrates between fresh and saltwater.

Barnacle geese were thought to come from barnacles because they breed in the Arctic in the summer, so nobody saw any eggs.
Also so they could be considered fish and eaten on Fridays.

This is pretty big for the European Eel, since it has a long history of confusing humans on how it lives.
Europeans never saw any juvenile eels, or eels spawning, or eel eggs, so they thought they came from earthworms, or spontaneously generated. Eventually it was discovered that eel larvae in the oceans were not a separate species, and in fact transitioned from larva to "glass eels", then to "yellow eels", and finally "silver eels" when they return to the ocean from the continent.
Silver eels also don't have a digestive system and migrate on stored energy alone.
