How was Earth formed? New Research reveals exciting answers regarding similar chemical origin in Earth and Planetary Objects

In 2005, a small variation in 142Nd was detected between chondrites, which are stony meteorites, considered essential building blocks of the Earth and terrestrial rocks

  • Neodymium-142 (142Nd) is one of seven isotopes found in the chemical element neodymium which may explain the origin of Earth and Solar system
  • In 2005, the small variation in 142Nd was detected between chondrites, which are stony Meteorite
  • These results were widely interpreted as an early differentiation of the interior of the Earth and these chondrites within the first 30 million years of its history

Ontario, September 15, 2016: Neodymium-142 (142Nd) is one of seven isotopes found in the chemical element neodymium which is widely distributed in the Earth’s crust and most commonly used for magnets in commercial products like microphones and in-ear headphones.

These results were widely interpreted as an early differentiation of the interior of the Earth (including the crust and mantle) and these chondrites within the first 30 million years of its history.

The new results published in the journal Nature from Bouvier and Boyet showed that these differences in 142Nd were in fact already present during the growth of Earth and not introduced later, as was previously believed.

“How the Earth was formed and what type of planetary materials were part of that formation are issues that have puzzled generations of scientists. And these new isotopic measurements of meteorites provide exciting answers to these questions about our origins and what made the Earth so special,” said Audrey Bouvier, Cosmochemist at the Western University.

    While everyone is busy making this planet come to an end
    Its really nice to read how Earth came into existence.

Non-invasive brainwave technology can potentially cut post-traumatic stress

The technology works through resonance between brain frequencies and the acoustic stimulation, where the brain is supported to make self-adjustments towards improved balance and reduced hyperarousal. It requires no conscious or cognitive activity.

  • The new technology aims to reduce the effect of post traumatic stress in an individual.
  • It can reduce many post-traumatic symptoms, including insomnia, depressive mood and anxiety.

Researchers have developed a non-invasive brainwave mirroring technology that can significantly reduce symptoms of post-traumatic stress, especially in military personnel.

Post-Traumatic Stress Disorder (PTSD) is a disorder characterised by failure to recover after experiencing or witnessing a terrifying event.

The symptoms include insomnia, poor concentration, sadness, re-experiencing traumatic events, irritability or hyper-alertness, as well as diminished autonomic cardiovascular regulation.

“Ongoing symptoms of post-traumatic stress, whether clinically diagnosed or not, are a pervasive problem in the military,” said lead investigator Charles H. Tegeler, professor, Wake Forest Baptist Medical Centre in North Carolina.

“Medications are often used to help control specific symptoms, but can produce side effects. Other treatments may not be well tolerated, and few show a benefit for the associated sleep disturbance. Additional non-invasive, non-drug therapies are needed,” Tegeler added.

In the study, published in the journal Military Medical Research, the team used a high-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM) — a non-invasive method, in which computer software algorithms translate specific brain frequencies into audible tones in real time.

This provides a chance for the brain to listen to itself through an acoustic mirror, Tegeler said.

The results showed reductions in post-traumatic symptoms, including insomnia, depressive mood and anxiety after six months of using the brainwave technology.

The technology works through resonance between brain frequencies and the acoustic stimulation, where the brain is supported to make self-adjustments towards improved balance and reduced hyperarousal. It requires no conscious or cognitive activity.

The net effect is to support the brain to reset stress response patterns that have been rewired by repetitive traumatic events, physical or non-physical, the researchers said. IANS
