Plants, like all living things, need nitrogen to build amino acids and other essential biomolecules. Although nitrogen is the most abundant element in air, the molecular form of nitrogen found there is largely unreactive. To become useful to plants, that nitrogen must first be "fixed," or busted out of its molecular form and linked with hydrogen to make ammonia. The plants can then get at it by catalyzing reactions with ammonia.
But plants can't fix nitrogen. Bacteria can.
Some legumes and a few other plants have a symbiotic relationship with certain bacterial species. The plants build specialized structures on their roots called nodules to house and feed the bacteria, which in turn fix nitrogen for the plants and assure them a steady supply of ammonia. Only 10 families of plants have the ability to do this, and even within these families, most genera opt out. Ever since the symbiosis was discovered in 1888, plant geneticists have wondered: why? If you could ensure a steady supply of nitrogen for use, why wouldn't you?
A global consortium of geneticists sequenced and compared the genomes of 37 plants—some symbiotic, some not; some that build nodules, some not; some agriculturally relevant, some not—to try to find out what was going on. The group's genetic analysis of the conundrum was reported in Science.

Kind of like SoylentNews rejecting its most prolific submitters? Some of us are legumes, and some of us are not. If you continue to suppress the aristarchus, this site is doomed. Not a threat, just a fact. Look it up.

Umm... I don't quite feel that S/N needs supplements of nitrogen in the form of piss, magister.
How about a nice course of ethics, part 2 and beyond?
Here, an idea of extension: "relation between society ethics and economy type - a comparison between ethics in capitalism, social democracy and socialism" with an addendum of "Brief guide for the ethics-deficient alt-right and/or neonazi individuals"

Yes, Padewan, I was just working on the second installment of Ethics for Soylentils. But then my three or four pending submissions (one of them admittedly just whining) were summarily rejected, with this message:
I did not even know that JR had a STEM, or that he was any from of plant life. I will be more careful in the future.
Part two of Ethics for Soylentils is more aimed at the libertarians, making a deontological case for the existence of categorical imperatives, and the utter futility of subjectivist theories of value. Might be fun. We may even make into Hegelian critiques of bourgeoise ethics of "right", if we keep this up. But as it is, I am still being oppressed! Hey! See the violence inherent in the system! I'm being oppressed! You saw JR oppressing me, just then, right? This is what I am on about!

To be honest, both of you guys tend to be assholes. Go get a room, or take it outside, or anywhere else but here. None of us is better of with you squabbling on this site.

No matter how much repetitive rubbish you submit, it doesn't make it any more attractive. I've just rejected 5 submissions related to the alt-right because none of them say anything new nor would any of them promote an intelligent and enlightening discussion. Why don't you submit them to a more appropriate site? Your acceptance rate of 7 stories out of 117 submissions should tell you something about the only topic that you seem to be able to write a submission on. We are not ignoring or suppressing the topic - but we have discussed it and there is nothing original in what you are offering.

Tell it to the TMB, janrinok. The Broad Brush is coming for SoylentNews. In fact, we are already painted, and only aristarchus is standing up for the side of reason. Continue, if you want to continue to kill the dream that was BuckFeta!

Running the bulk of your alt-right related submissions would have run the site into the ground a long time ago. Even if we cared about the toxic subject matter, most of them are heavily biased or about worthless attention seekers. We don't need to know what Milo or Lauren are doing week to week.

Ouch! How did that happen? Sabotage? or Paranoia? You pick. Re-submitted, not likely to be accepted, since the RDJT is journaling it, since it is the biggest cancellation since "The Apprentice"!!!!!!
