STEM Saturday on the Steem blockchain, Week #48: Ancient beetles and mapping Mars

STEM Saturday Digest - April 22, 2023

This week's topics come from the fields of paleontology and space exploration.

Please visit the /promoted page to view this week's STEM Saturday post promotions.

This was the 48^th week of our post promotions for STEM Saturday on the Steem blockchain, and our little community now occupies the top of the /promoted page for the 48^th consecutive Saturday. This week, I promoted two Science, Technology, Engineering, and Mathematics (STEM) posts.

If you are a STEM enthusiast, please consider following the authors that you'll find in this article and also consider joining our community. If you would like your own post to be considered for STEM Saturday post promotion, please see the guidelines at the end of this post.

This week's promotions included the following posts (in alphabetical order, by author). Each author has been set as a 5% beneficiary on this post. All posts were passed through three different online plagiarism checks and three different checks for AI detection.

New maps of Mars, with never before seen levels of detail have been produced by the UAE Space Agency's Emirates Mars Mission and Cal Tech's Murray Lab. The UAE's map was produced by the Hope Probe, which has been orbiting Mars since 2021. The Caltech map is interactive.

Representing the first evidence of a symbiotic relationship between arthropods (invertebrate animals with exoskeletons), a paleontology team led by Enrique Peñalver
has discovered a 100 million year old sample of amber that contains the fossilized remains of dinosaur feathers and beetle larvae. From analyzing this sample, the team concluded that the beetles benefited from the dinosaurs by feeding on their feathers, and in return, that their activity served to keep the dinosaurs clean. Because of the age of the feathers, it is known that these feathers were not left behind by a flying species because dinosaur flight had not yet evolved.

About STEM Saturday

If members would like to have your own STEM content considered for future promotions, please come join us and start contributing. I don't know how long I'll be continuing the tradition, but while I do, here are the minimum requirements for consideration (subject to change without notice ;-).

1. Original, plagiarism-free content
2. Minimum word count: currently 300 words, but this may be adjusted.
3. The content must not be cross-posted on other web sites or blockchains. Correct use of the #steemexclusive tag is encouraged.
4. English language. (sorry, it's the only one I know)
5. Because a post leaves /promoted at payout time, posts created shortly before STEM Saturday may be more likely to be chosen than older posts.

All community members are invited to create original and exclusive content that can be considered for future promotions.

Please help grow the science & technology audience on the Steem blockchain by following the Science and Technology on the Social Blockchain Facebook page then liking & sharing our links!
