“The earth is bountiful, and where her bounty fails, nitrogen drawn from the air will refertilize her womb.”*…
As the Iran War continues to unfold, there is understandably a great deal of concern about energy prices (and the prices of things that depend on energy). We might forget that the Middle East is also crucial to the world’s fertilizer supply– though not for long, as farmers (along with everyone else in the food chain, all the way down to all of us eaters) are beginning to feel the pain.
But, as Diana Kruzman reports, even as fertilizer trade concerns are growing, a revolutionary sourcing alternative has emerged– one that could make a huge positive difference if it proves out at scale…
The world has an almost insatiable demand for nitrogen. Crops need it to grow, but although it makes up 78 percent of our atmosphere, plants can’t just pull it in from the air the way they do with oxygen. Instead, they rely on bacteria in the soil to convert it into nitrate, a form they can use; in the case of agriculture, think of fertilizer spread by humans. Leaving aside organic options like cow manure, most farmers use ammonia produced mainly from natural gas using a technique called the Haber-Bosch process, which was invented in 1909. [See also here.]
Haber-Bosch is expensive and energy-intensive, responsible for up to two percent of the world’s annual greenhouse gas emissions. It’s also spurred a global nitrogen pollution crisis; as much as two-thirds of nitrogen fertilizer applied to crops is never used, and the excess escapes into the soil, air, and water, raising the cancer risk in nearby communities and contributing to climate change.
Researchers have been trying to find an alternative way to get nitrogen to plants for decades — turning to everything from microbes to human urine. But so far, these scientific advancements haven’t translated into much practical change for farmers, who for the most part still rely on ammonia (which, granted, is getting greener, but is increasingly vulnerable to global price shocks).
That could soon change with the growth in popularity of a new technology known as plasma activated water, or PAW. Around the U.S., scientists and startups are experimenting with this high-tech solution, which uses electricity to pull nitrogen from the air, mix it with water, and create fertilizer straight on the farm. The concept, on the surface, seems suspiciously rosy — on-demand nitrogen, in a form plants can use, at just the cost of electricity (and the initial price of the machine used to make it). But early adopters have told Offrange that it genuinely works…
… PAW uses electricity to transform air into plasma — the fourth state of matter (besides gases, solids, and liquids), which typically forms at high temperatures. When the plasma comes into contact with water, it encourages chemical reactions that form nitrates — the type of nitrogen that plants need. Though this process was actually invented in 1903, even before Haber-Bosch, it required so much energy that it never achieved widespread use.
But in recent years, those energy needs have gone down thanks to the development of “cold plasma” technology, which operates at less than 60 degrees Fahrenheit. It’s also used for medical sterilization and food safety, and over the last decade researchers have worked to develop new ways to apply it for agricultural production…

As we count on creativity, we might send healthy birthday greetings to a man who explained one of the central ways in which we depend on the food that we eat, William Cumming Rose; he was born on this date in 1887. A biochemist, he researched amino acids, discovered threonine, and established the importance of the nine essential amino acids in human nutrition (that’s to say, the amino acids that our bodies cannot synthesize and that we must consume in our food). He received the National Medal of Science in 1966.

#NASA Finds Building Blocks Of Life On Frozen Asteroid
Scientists have found evidence that #aminoacids, the chemical building blocks of life (specifically proteins), formed on the asteroid #Bennu when it was so far from the Sun as to be frozen. This directly contradicts previous belief that amino acids required liquid #water to form, through a process called Strecker synthesis. The scientists studied samples from Bennu retrieved by NASA's #OSIRISREx, published last week.

#Scientists Make Breakthrough in Solving the Mystery of Life’s Origin
For years, researchers have puzzled over how two ingredients for life, first linked up on early #Earth. Now, they’ve found the “missing link,” and demonstrated this reaction in the lab.
This biological process, #RNA & #AminoAcids had to become attached at some point. This key step, known as RNA aminoacylation, has never been experimentally observed in early Earth-like conditions.

My phyiscs and #cfd background did not prepare me for the madness of abbrivations for amino acids (okay the three letter ones are fine).
Why is Selenocysteine = U, there is not even a single u in the word. What is the logic to the one letter abbriviations?
