Scientists Create Speech From Brain Signals


 
On the Black Hole's Non-existence.Space News....Listen to PART TWO of the interview recorded on April 8, 2019, with physicist Wal Thornhill. He sheds light on the fact that the recent so-called "first picture of a black hole" actually affirms the plasma cosmology hypothesis that the object at a galactic core is a Plasmoid. Find out why black holes are not needed in the Electric Universe model.

Black Hole or Plasmoid?Space News....In this interview recorded on April 8, 2019, physicist Wal Thornhill discusses why the recent so-called "first picture of a black hole" actually affirms the plasma cosmology hypothesis that the object at a galactic core is not a black hole at all but an ultra-high density energy storage phenomena called a Plasmoid.

The first laser radio transmitter....Researchers transmit data via a semiconductor laser, opening the door to ultra-high-speed Wi-Fi
In a paper published in the Proceedings of the National Academy of Sciences, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) demonstrated a laser that can emit microwaves wirelessly, modulate them, and receive external radio frequency signals.

Anti-Vaccination; Pro-Science; Pro-Health; Anti-Industry....
The concept of intrusive protection has existed since a very long time. They were directed against smallpox as the disease was persistent and deadly. Prior to vaccination there were three practices; olfaction, inoculation and variolation. These failed because of three reasons; they led to serious adverse effects, increased the death rate and helped the disease to spread among populations where they were practiced. By 1728 the medical profession knew very well that these concepts would not work.
Therefore when Jenner came out with similar concept eyebrows were raised. The smallpox vaccination was accepted upon a single case of James Phipps who after operation in May 1796 survived a disease challenge, and it was assumed the immunity was for life. However the incidence rapidly increased and the promised period of immunity reduced progressively from a lifetime to six months. Repeated revaccination was suggested which suited those implementing the practice for a handsome fee.

Introduction to Effective Microorganisms (EM)....This EM Info website is intended to provide a complete introduction to a technology generically known as Effective Microrganisms (aka EM) and it's uses in many fields, including agriculture, waste remediation, odor control, and human and amimal health. Throughout this website, the simple and generic abridgement "EM" will be used as an abbreviation to denote the general class of microbial consortia known as Effective Microorganisms (and known as well under many other names.)

Fooling automated surveillance cameras: adversarial patches to attack person detection....Adversarial attacks on machine learning models have seen increasing interest in the past years. By making only subtle changes to the input of a convolutional neural network, the output of the network can be swayed to output a completely different result.

250+ Examples of Natural Remedies Beating Pharmaceuticals....
One of the greatest if not the greatest triumph of biomedical science today is its role in validating ancient healing modalities that long before the advent of science, and even recorded history itself, were passed down "orally" from generation to generation in the vast body of folkloric medical knowledge that still forms the basis for the majority of the world's primary health care system.
These so-called "natural" or "alternative" modalities, which our species owes its present day survivorship to after eons of dependency on them, are increasingly gaining the attention of men and women in white lab coats intent on unlocking the mysteries of how they work, and in many cases, why they work better than patented, synthetic, chemical-based medications.

What is more fundamental, field or particles?...Occasionally, we link to some intense debates among regressive physicists.
Astute readers, of course, will recognize this as a non sequitar. Fields, as anointed by Einstein and other positivists,are considered “immaterial.”That is,they contain nothing whatsoever,they are the empty space that was a consequence of his early ether denial.Nonetheless,these matterless “fields” still supposedly caused phenomena such as gravitation and magnetism just as the equations predicted.The matterless ideal perseveres.For instance, according to the popular press the shock wave measured in the LIGO experiment supposedly resulted in a “gravitational wave” that caused the compression and decompression of empty space or “spacetime.” They nevertheless regarded this ridiculous interpretation as yet another proof that “Einstein was always right.” There was not even a hint that it was yet another proof that a medium was necessary for the transmittance of the wave.... show more

Brain signals translated into speech using artificial intelligence

In an effort to provide a voice for people who can’t speak, neuroscientists have designed a device that can transform brain signals into speech.

This technology isn’t yet accurate enough for use outside the lab, although it can synthesize whole sentences that are mostly intelligible.

Scientists create decoder to turn brain activity into speech

Scientists have developed a decoder that can translate brain activity directly into speech.
In future the brain-machine interface could restore speech to people who have lost their voice through paralysis and conditions such as throat cancer, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease.
Of course, this won't be put to any kind of wrong use at any time in the future...

And I'm sorry - this page is for a busnees - see lsxs.no. But I won't do commercials in here. This will be my alternative to other more populated communities. Based in Oslo, Norway I move around in Scandinavia / the nordic countries a lot.

Earth vs. asteroids: humans strike back

Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the first time: Japan’s Hayabusa2 spacecraft dropped a copper projectile at very high speed in an attempt to form a crater on asteroid Ryugu. A much bigger asteroid impact is planned for the coming decade, involving an international double-spacecraft mission.
