This is a collaboration with @dragonslayer109
Today I have chosen three Science & Technology-related posts (including "popular science" kind of posts) which in my opinion deserved more success, because of quality of content and/or timeliness and importance of the topic. I should perhaps clarify that I focus on posts which can be understood by the average Steemer. This is not about academic excellence per se!

50% of the SBD earnings will be sent to the authors of the featured posts (split in equal parts).
