Uncovering the Secrets of Dark Matter

 


An international team has created a novel approach to understanding the secrets of dark matter. Scientists from Queensland Australia and Germany’s metrology Institute (the Physik-alisch-Technique Bundesanstalt, PTB) are teamed up. 

The group used information from both atomic clocks and cavity stabilized lasers. The lasers are located far apart in space and time. The lasers are being used to search for types of dark matter that were previously invisible. The procedure allows scientist to detect signals from dark matter models. These signals interact universally with all atoms, previously this process has been elusive to science during traditional experiments. 

The group broke down data from a European laser. Originally reported in 2022, the European network used ultra stable lasers that are connected by fiber optic cables. The team also analyzed atomic clocks on board GPS satellites. The researchers compared precision instruments across vast distances. The data became sensitive to oscillating dark matter fields. These fields are normally canceled out in conventional set ups.

 The team originally published their work in physical review letters.

The study shows how powerful international collaboration can be. Scientists are now researching a bigger range of dark matter scenarios. The method brings us closer to understanding the universe’s elusive and most important concepts.

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’....
