“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…

* Nikola Tesla (who, around 1900, imagined and experimented with something like the Birkeland–Eyde-based plasma process described above)

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.

Protein Variety and Complete Amino Acids 🥗🍗

Understanding protein variety is crucial because muscles aren’t built from protein alone, they’re built from the building blocks of protein: amino acids.

🥦 Amino Acid Synergy: Beyond Protein Intake 🥗

Muscle protein synthesis (MPS) depends on a full spectrum of essential amino acids (EAAs), not just a high protein intake.

We identified protein domains in LUCA (#LastUniversalCommonAncestor). Their distinctive #AminoAcid usage reveals the order amino acids were added to the #GeneticCode, based mostly on size.

2 #aminoacid residues in N-terminal region of #polymerase acidic protein determine #virulence of Eurasian avian-like #H1N1 swine #influenza viruses in mice, J Virol.: https://journals.asm.org/doi/full/10.1128/jvi.01293-24?af=R

We identified that 2 naturally occurring aa mutations in PA derived from #H1N1/2009 are crucial determinants of virulence of rEA H1N1 viruses & revealed differential mechanism by which these 2 mutations affect transcription & replication of vRNA.

#Genetic & #molecular characterization of #H9N2 avian #influenza viruses in #Yunnan Province, SW #China, Poul Sci.: https://www.sciencedirect.com/science/article/pii/S0032579124006199?via%3Dihub

Analysis of these #aminoacid sites suggests that H9N2 influenza viruses in Yunnan continue to mutate and adapt to #mammals & are sensitive to #neuraminidase #inhibitors but resistant to #adamantanes. It is necessary to strengthen surveillance of AIV H9N2 subtypes in poultry and LPMs in Yunnan to further understand their genetic diversity.

#Aminoacid #mutations #PB1-V719M and #PA-N444D combined with #PB2-627K contribute to the #pathogenicity of #H7N9 in #mice, Vet Res.: https://veterinaryresearch.biomedcentral.com/articles/10.1186/s13567-024-01342-6

Overall, this study revealed that #virulence in H7N9 is a #polygenic trait and identified novel virulence-related residues (PB2-627K combined with PB1-719M and/or PA-444D) in viral ribonucleoprotein (vRNP) complexes.
