Welcome to the 27th Daily Field Note! Here you find the top post of the day, one covering each scientific field that is included by Geopolis. Since these authors put a lot of effort in writing a good post they surely deserve the extra exposure.
Geopolis is a project to promote and connect authors who write in the fields of global sciences. Upvotes are currently worth more than $1,50 so don't hesitate to get involved or become a member for higher rewards! You can read more about the project and how to join here:

Subjects curated by Geopolis are Geography, Anthropology, Ecology, Geology, Archeology and certain branches of History.
Anthropology: How Do We See Our Children?
Children are the future of all societies and therefor it is very interesting to examine how different cultures see their children. 
Children are our little angels, right? They are innocent, fragile, infinitely cute and we do everything to please and protect them. They are priceless to us and they have become the center of our world. They are our cherubs. Photo by Leo Rivas on Unsplash This view of children is actually quite new in the human species, and is typical for the so-called WEIRD societies . It emerged somewhere in the last 150 years in Europe, North America and parts of East Asia. The main characteristic is that the child becomes the center of the family , and the parent-child relationship is, most often, a one-way street, meaning that the parent has endless responsibilities and duties towards the child,...
Geography: Cultural Geography: Ancient River Valley Civilizations – Hymns to the Nile & Pharaoh
Ancient Egypt is a very well known and studies society. It has a long history and has known many technical and cultural advances. For such large societies to remain united, a very strict believe system had to be present. This was obtained by the Farao as an iconic leader, and the Nile which was a lifeline and worshiped by the people. To read more about this wonderful piece of history, check out this post from
@keephy.As the first societies of the world began to form, key rivers and religious leaders played a significant role in the development of many ancient cultures. Amongst ancient societies, one of the best examples of this trait is ancient Egypt. There are two religious poems that originated in ancient Egypt that help solidify this argument. They are called Hymn to the Nile and Hymn to the Pharaoh. Within these two hymns there is an abundance of information supporting the theory that the Nile River and the pharaoh played an integral role in the continuity of the Egyptian kingdom over the course of millennia.

Geology: Sixteen Tons Part 2: The Environmental and Human Costs of Coal
Yesterday 
In any discussion of the negative effect of human use of coal, it's almost hard to know where to start. Considering its current prominence in the media, however, let's start with coal's contributions to climate change. To sum coal's contribution to climate change up quickly: It's the single largest contributor of CO2 to the atmosphere, bar nothing. It comprises 46% of all total carbon dioxide emissions globally and 72% of all global carbon emissions from the electrical generation sector. Coal produces nearly twice as much CO2 as natural gas per unit of electricity generated- and natural gas can hardly be called green energy. How's coal s...
Ecology: The hunt is on: Bacteria that eat other bacteria
Bacteria are often seen as organisms that feed on materials that others would see as waste, and a lot of that is true but their are some examples where evolution altered this idea. Some species evolved to become predators and use other bacteria as a source. To read more about these species and how this potentially could be used, check out 
Success in the bacterial world largely depends on your ability to get energy and raw materials. So, _if something can be eaten it's a good bet that there's a least one bug out there eating it_. This is why we have things like decomposition, fermented foods, and some infections. Bacteria themselves aren't off limits to being eaten by other bacteria and, sure enough, there are bacterial predators out there which use some pretty neat strategies to hunt their prey. I'd like to tell you all about three of the most popular of these fierce little creatures. Bdellovibrio and BALOS Perhaps the most well-known and studied bacterial predators are from the genus Bdellovibrio and its...
