Nanoplastics are Everywhere Heartsound Audio

 


Disposable cups, plastic bags, and packing materials are all examples of plastic used in our daily lives. They can, over time, become brittle and start shedding  small nano sized particles.

They can be found in the soil, food chain, “and in the blood” says Meiru Wang from Leiden University.      “Plastics have been found in human placentas.” 

Wang wanted to know what exactly happens when micro plastics end up in the blood of an embryo?

“During an earlier study, we discovered that a high concentration of nanoplastics can cause malformations in the heart, eyes, and nervous systems of Chicken embryos. For a more complete understanding of the toxicity of nanoplastics, we first need more information about how they spread from the blood throughout the rest of the body.” 

Scientists plan to use nanoplastics and other nanoparticles in drug delivery, so this information is imperative. 

Because nanoparticles are so small, Wang and her team tagged the nanoparticles with either fluorescence or Europium, A rare metal that is not normally present in the human body. 

Wang Reports, “ We found that the plastics can cross blood vessel walls, and that they accumulate in relatively high levels in the heart, liver and kidneys.”

Some nanoplastics are even excreted by the kidneys! 

It’s now understood how nanoplastic spreads, so researchers will begin investigating the health risks. The outlook? Not great.

“ There is already research linking nanoparticles to a higher risk of heart attacks and strokes. Especially during the development stage, nanoparticles could potentially be quite dangerous.”

Currently, it’s understood that doctors shouldn’t administer nanomedicines to pregnant women, as there is a significant chance the nanoparticles could reach and affect the developing organs of the baby.

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’....
