Unknown Compound Identified in Drinking Water



 A large team of scientists from Switzerland and the United States have released information about drinking water. It’s estimated that over 113 million people in the US are drinking chloraminated water. 

Researchers have discovered what they call chloronitramide anion. It is chemically written as Cl-N-NO(2)-

It is known to be the end product of inorganic chloramine decomposition. The toxicity is not fully understood, although its prevalence and sameness to other toxic compounds is extremely concerning.

Just identifying this new compound has been a big challenge for scientists. The new information was published in the journal Science. 

Julien Fairey is first co-author on the paper. He is an associate professor of civil engineering at the University of Arkansas.

Fairey explains that scientists have known about the compound for a few decades. Fairey himself began to work on the project about 10 years ago.

Fairey claims, “ It’s a very stable chemical with a low molecular weight. It’s a very difficult chemical to find. The hardest part was identifying it and proving it was the structure we were saying it was.” 

Scientists began to create the new compound in the laboratory. Juliana Laszakouits is a post doctoral researcher at ETH Zurich. Fairey sent her the sample to be analyzed. There are huge questions about the health risks of the new compound.  

Fairey explains, “it’s well  recognized that when we disinfect drinking water, there is some toxicity that’s created. Chronic toxicity, really. A certain number of people may get cancer from drinking water over several decades. But we have an identified what chemicals are driving that toxicity. A major goal of our work is to identify these  and reaction pathways through which they form.”

Recognizing this compound is key. Chloronitramide anion’s cancer causing health risks Will be the future work of agencies like the US environmental protection agency

Fairey summarizes, “ Even if it is not toxic, finding it can help us understand the pathways for how other compounds are formed, including toxins. If we know how something is formed, we can potentially control it.” 

Here’s hoping.

Mike Giradi from Stereotimes commentary on Holostage Room Treatments

I have been  friends with Mike Giradi for a few years and he has helped me test numerous designs .    I was so honored a few weeks ago when he agreed to give these Holostages a few words.  From. Mike G. The sound was a little closed in at first, but then it really opened up to prove it is another great audio product. The noise floor is greatly reduced. I am hearing details I've never heard before. When it's in the recording, the soundstage widens in all directions. The timbre of each instrument is spot on. The six Holostages installed in my room aided in the C13 alignment of air molecules to a far greater extent than the Bybee IQSE devices I had previously been using. Every instrument had greater depth, pop and presence. Listening to classical music on movie soundtracks is incredible now. The Holostages installed on my BACCH4MAC and monoblocks was the answer to what was needed. The noise floor dropped significantly in both cases resulting in greater clarity and music...

Queen Bee 🐝

  Bees hide an interesting secret. When the hive loses its queen, who alone is able to give life to the colony and maintain order in a perfectly organized society, all seems lost. The life of the hive slows down. Without new eggs, the future is lost. In a few weeks, the colony may be doomed. But the bees do not panic. Nor do they expect salvation from outside. Demonstrating extraordinary collective intelligence and profound instincts, they trigger spectacular emergency procedures, almost unimaginable in a world dominated by insects. --- ◆ The transformation begins with a simple but essential choice The worker bees choose common larvae - those who would normally be mere workers. They are nothing special. They are not born different. But their fate changes completely. They are chosen to receive a special food: royal jelly. A rare substance, produced by healthy bees, rich in proteins, vitamins and bioactive compounds. This is royal food in the purest sense of the word. The larvae fed ...

Novel Acoustic Wave Discovered

Image
  A new diffraction phenomenon was researched and published on January 14, 2025. The team was led by Tohoku University with collaboration from the Japan atomic energy agency and the RIKEN Center for emergent matter science. Surface acoustic waves (SAWs) are elastic vibrations. They travel along the surface of materials, not unlike ripples on a pond. SAWs are an important part of frequency filters used in every day devices like our cell phones. These devices change electrical signals in vibrations, or ripples. This occurs because of the piezoelectric  effect and it enables efficient signal processing. During this experiment, the team created a periodic array of magnetic nanoscale materials. The magnetic array is a sort of specialized grating that the waves passed through. The scientists were surprised. Instead of the usual symmetric defraction, the team saw something different. They observed a completely new, asymmetrical diffraction of SAWs called ‘non-reciprocal defraction’....
