Two weeks in a row! Welcome to the 97th issue of SteemSTEM Distilled, a curation effort by the members of the @steemstem team. Almost 100 of them!
Before getting to the selected posts of the week, feel free to meet us on the SteemSTEM discord server. we are there on a daily basis and happy to chat with anyone who would pass by.

We present in this distilled our top two handpicked post choices for the last week (from several hundreds of STEM-related posts on Steem). This week's distilled highlights were selected by a one-man team made of @lemouth.
Some statistics are given at the end of this post.
Please do not be discouraged if you did not make it on this issue. The chances to be picked are low. In the meantime, you may wish to check these guidelines for extra tips on how your writing could be more effective (or ask us on Discord.
Our top choices
Allergies and the defence against diseases #2

Did you ever want to know how our good old human body was reacting to external attacks? @loveforlove wrote a very nice post (actually, a second very nice post) where the major role of B-cells and T-cells is highlighted. On top of that, a few words about vaccines and how they function. if you are interested, feel free to pass by!
Cosmology: The strange darkness, Olbers' Paradox and the main features of the Universe.

For the second post pf the week, let us go directly far into the star. @emperorhassy tells us many things about stars (and how we can observe them), as well as galaxies and their different forms. A post to go far into the sky, that is worth a read!
Statistics
SteemSTEM offers support to anyone using our app, steemstem.io. We recall that:
- Posting an article through the app automatically yields a 5% stronger upvote at curation time.
- Posting a reply to an article (or to another reply) from the app can sometimes yield some SteemSTEM support.
- Setting @steemstem as a beneficiary to the post automatically yields a stronger upvote (up to 5%).
Last week, the SteemSTEM curator teams have supported 60 posts written by 44 authors. 25 of these posts have been posted through the app (and got a 5% stronger upvote). Among these 60 posts, we find:
- 19 small upvotes (less than 20%)
- 11 medium upvotes (in the 20%-50% range)
- 30 large upvotes (larger than 50%)
We have not upvoted any comment posted through the app (because there is a bug in the script to be fixed...).
The list of upvoted post authors, potentially getting some extra support from @curie and/or @utopian-io, is:
