As a moderator of this community, I feel that Google+ needs some really important features to avoid spam. I've already posted them in "feedback / feature request" but Google being Google won't implement it unless a lot of people post the same request. These feature requests are:

0) Posting limit at a given time. There should be a difference of at least 5 mins between postings from the same user. Google should block users from posting for 5 mins after every post. *This will be magical*.

1) Blacklisting and whitelisting Domains. Some good urls fall into spam while bad ones in community.

2) Whitelisting users. They already give an option to ban users so it's the same as blacklisting. Some users always post relevant contents but their posts fall into spam. This hurts community.

*Please share this with other community moderators as well*. You can just copy paste these points in feature request. Make sure to post these three separately as Google takes one suggestion at a time. So, if you paste exactly this, it'll take the first point only. Adios!

Soil is a mixture of small rocks, minerals, humus and also various microbes. It is formed by the weathering of rocks that is occuring since the begining of life on earth.

Today on the 19th of November 1711, Mikhail Lomonosov was born. He was a Russian polymath, scientist and writer, who made important contributions to literature, education, and science. Among his discoveries were the atmosphere of Venus and the law of conservation of mass in chemical reactions. His spheres of science were natural science, chemistry, physics, mineralogy, history, art, philology, optical devices and others. Lomonosov was also a poet and influenced the formation of the modern Russian literary language.

✨🇲️🇦️🇬️🇮️🇨️🇦️🇱️ 🇺️🇳️🇮️🇻️🇪️🇷️🇸️🇪️ - IC 443 by Fényes Lóránd

Like a gelatin candy, the Medusa Nebula, cataloged as IC 443, sits placidly in space. But not everything is what it seems, the Medusa is today the remnant of an immense supernova explosion, the end of the life of a massive star. As we can see, the nebula shines in an intense red color with blue tints, the red one comes from the hydrogen atoms that are ionized by the ultraviolet radiation of the young and hot stars. The same thing happens with oxygen, but to a lesser extent. IC 443 is in the direction of the Constellation of Gemini, part of it is located in the Constellation of Beaver, and is located about 5,000 light years away from Earth. We are therefore, seeing the conditions of the nebula when the kingdoms of high and low Egypt were forming, although not much has changed since then, the image reflects as it was in the year 3,000 BC. But when did the star that generated this remnant explode? It has not yet been possible to define with precision, but it is estimated that the progenitor star exploded between the years 3,000 a.C. and 30,000 a.C. The IC 443 nebula is one of the best examples of how the.....

"Rare microbes lead scientists to discover new branch on the tree of life:
Hemimastigotes are more different from all other living things than animals are from fungi" (Nova Scotia, Canada) by Emily Chung (+CBC News).

[Caption with featured image: "This is an electron microscope image of Hemimastix kukwesjijk, named after Kukwes, a greedy, hairy ogre from Mi'kmaq mythology. Its 'mouth' or capitulum is on the left. (Submitted by Yana Eglit {+Yana Eglit}.)"]

From the attached article...

Canadian researchers have discovered a new kind of organism that's so different from other living things that it doesn't fit into the plant kingdom, the animal kingdom, or any other kingdom used to classify known organisms.

Two species of the microscopic organisms, called hemimastigotes, were found in dirt collected on a whim during a hike in Nova Scotia by Dalhousie University (+Dalhousie University) graduate student Yana Eglit.

A genetic analysis shows they're more different from other organisms than animals and fungi (which are in different kingdoms) are from each other, representing a completely new part of the tree of life, Eglit and her colleagues report this week in the journal Nature (+NATURE).

"They represent a major branch… that we didn't know we were missing," said Dalhousie biology professor Alastair Simpson (+Alastair Simpson), Eglit's supervisor and co-author of the new study.

"There's nothing we know that's closely related to them."

In fact, he estimates you'd have to go back a billion years — about 500 million years before the first animals arose — before you could find a common ancestor of hemimastigotes and any other known living things.

The hemimastigotes analyzed by the Dalhousie team were found by Eglit during a spring hike with some other students along the Bluff Wilderness Trail (+The Bluff Wilderness Hiking Trail) outside Halifax a couple of years ago. She often has empty sample vials in her pockets or bags, and scooped a few tablespoons of dirt into one of them from the side of the trail.

Back at the lab, she soaked the soil in water, which often revives microbes that have gone dormant, waiting for the next big rainstorm. Over the next few weeks, she checked on the dish through a microscope to see what might be swimming around.

=== Strange movements ===

Then, one day, about three weeks later, she saw something that caught her eye — something shaped like the partially opened shell of a pistachio. It had lots of hairs, called flagella, sticking out. Most known microbes with lots of flagella move them in co-ordinated waves, but not this one, which waved them in a more random fashion.

"It's as if these cells never really learned that they have many flagella," Eglit said with a laugh. She had seen something with that strange motion once before, a few years ago, and recognized it as a rare hemimastigote.

Hemimastigotes were first seen and described in the 19th century. But at that time, no one could figure out how they fit into the evolutionary tree of life. Consequently, they've been "a tantalizing mystery" to microbiologists for quite a long time, Eglit said.

Like animals, plants, fungi and ameobas — but unlike bacteria — hemimastigotes have complex cells with mini-organs called organelles, making them part of the "domain" of organisms called eukaryotes rather than bacteria or archaea.

About 10 species of hemimastigotes have been described over more than 100 years. But up until now, no one had been able to do a genetic analysis to see how they were related to other living things.

Realizing that she had something very rare and special, Eglit flagged another graduate student Gordon Lax (+Gordon Lax), who specializes in genetic analyses of individual microbes — a new and tricky technique — to see where they fit in the evolutionary tree. The pair dropped everything to analyze the new microbe.
