Welcome to the 27th episode of the #stemng digest series where we bring to you some of the best posts under the #stemng tag in the past week.

For those that do not know yet, stemng is a sub-community of steemSTEM, a community-driven project which seeks to promote well-written and informative Science, Technology, Engineering and Mathematics posts by Nigerians on Steemit. The project involves submitting quality STEM-related posts to the steemSTEM management for upvoting and resteeming where applicable.

As we usually do, we have sifted through the stemng tag and even though there were several good posts to choose from, below are the posts that stood out for week #26.


<br>

### Saturday: [Let's talk about one of the rarest cancers in humans [Nasal cancer]](https://steemit.com/steemstem/@akiripromise/let-s-talk-about-one-of-the-rarest-cancers-in-humans-nasal-cancer-05d555513a59f)


<div class="pull-right">https://cdn.steemitimages.com/DQmR9vaEZVoUVGKhbzkXzph4vQvMR8yomLxULfz1djpQjAt/image.png</div>

Flagging off this week's selection is this post on nasal cancer by @akiripromise. The possible causes, associated risk factors, different stages of diagnosis and the currently available options for treatment were extensively discussed by the author. A good read I would recommend to any STEM enthusiast.

### Sunday: [Malaria Prevalence, Mosquito net Preventive Therapy and Future Implications: A case study of Ogun state, Nigeria](https://steemit.com/steemstem/@teemike/malaria-prevalence-mosquito-net-preventive-therapy-and-future-implications-a-case-study-of-ogun-state-nigeria)


<div class="pull-left">https://cdn.steemitimages.com/DQmPCgbSrYa5AbU13MeCr9gejwMVgodGC2xVycvjNTL35mM/image.png</div>

Malaria is a disease that has killed more humans than HIV would probably ever and one of the prophylactic method used in preventing the disease is to prevent its vector from getting access to human through the use of mosquito net. This article by @teemike took a dive into the possible implications of mosquito net preventive therapy of malaria using a state in Nigeria as a case study.

### Monday: [WHAT IF GHOSTS EXIST IN REAL LIFE?](https://steemit.com/steemstem/@rareghost/what-if-ghosts-exist-in-real-life)

<div class="pull-right">https://cdn.steemitimages.com/DQmT8CNetduHAdnS3dwWNZGjAVmQGweQuXeE66wefV5F21n/image.png</div>
@rareghost wrote about the possibility of the existence of ghosts in real life. A very interesting piece that encompasses psychology and a lot of physics. Prepare to enjoy yourself before clicking to read.

<br>


### Tuesday: [Smart Cards, A chip with so much applications](https://steemit.com/stemng/@henrychidiebere/smart-cards-a-chip-with-so-much-applications)


<div class="pull-left">https://cdn.steemitimages.com/DQmbNykVQj4JZwsJb6XoFWZe1MyuxJFAX5Bj98yC9ekDptr/image.png</div>

This post by @henrychidiebere explained the various applications of smart cards in our everyday lives. Not just that, the history, architecture, security and the various modes of communication employed by smart cards were extensively discussed. Quite an educative piece.


<br>


### Wednesday: [An introduction to Water -- Properties, importance, and the distribution of water](https://steemit.com/steemstem/@pangoli/an-introduction-to-water-properties-importance-and-the-distribution-of-water)


<div class="pull-right">https://cdn.steemitimages.com/DQmfFjmqNKFkdB16Rk8DMWPsqBYq8rkK2gsZCCu3s8qa9RG/image.png</div>
Water, e no get enemy! @pangoli would have been a friend to Fela Anikulapo (if you know, you know!) for writing on the science of water. The various sources available, distribution and properties of the universal solvent was discussed in this post. Kudos to the author.



<br>




### Thursday : [Why Are There So Many Missing Links In Human Evolution? [Concept Of The Transitional Fossils]](https://steemit.com/science/@samminator/why-are-there-so-many-missing-links-in-human-evolution-concept-of-the-transitional-fossils-bdb25e2052c6f)


<div class="pull-left">https://cdn.steemitimages.com/DQmZFqZZC4D4gEA9e6mXCAGwuxMrYRZiLkXLPUvgMQmQFSc/image.png</div>

There is no doubt that evolution is an important process in the existence of humans and without it, perhaps we won't even be here. However, a lot of questions are yet to be answered as far human evolution is concerned and @samminator tried to discuss some of the relevant issues. A good read, I must admit.

 
<br>


### Friday: [Can petrol engines run on alcohol? Lets find out!](https://steemit.com/stemng/@rharphelle/can-petrol-engines-run-on-alcohol-lets-find-out)

<div class="pull-right">https://cdn.steemitimages.com/DQmSLRzitUuCShbcJEdxMx6stJXqQTauPo8AWNw6swbtyiF/image.png</div>

Rounding off the selection for week 27 is a post that tried to answer a question of whether petrol engines can run on alcohol. We all know that fossil fuels would get exhausted one day and alternatives need to be sought. @rharphelle was the author here and he did a good job with it.
