This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
Roughly, yes, depending how wide your lens is and precisely what you mean by structure. Most airborne viruses are RNA based, but many bloodborne pathogens (Ebola, HIV, HCV, etc) are also RNA viruses. If you meant shape, icosahedral is most common but there's plenty of variety and overlap between bloodborne/airborne (Ebola is long and filamentous).
More than 'structure' (depending what you meant by that), you should pay attention to tropism. Ebola expresses surface proteins that enable it to initially infect immune cells, then various endothelial (blood vessel) and other structural cells which are not accessible in the airways. COVID has a surface protein that binds ACE2, which is expressed on the surfaces of airways, part of the gut, etc. Other viral proteins are also key for proliferating in a given cell type, but you can get a lot of mileage out of just looking at the spike proteins and which receptors they bind.
Could you make turbo airborne Ebola by grafting COVID spike protein onto the surface of the Ebola capsid, and misting some into a volunteers face? Hey, sounds like a Nature paper to me!
...but also probably not, I doubt it would work without a pretty significant engineering effort beyond that simple change. So more akin to cars flying like planes. I'm not aware of any viruses that are known to have drastically changed routes of transmission like that.
I was thinking things like size, envelope, and things like that. IIRC norovirus is physically robust as viruses go: is that a trade off against airborne transmission? But it's been a long time since I took a biology class.
