Telepathic Therapy: Brain Waves Are Used To Remotely Control DNA-Based Nanobots

A team of Israeli scientists developed a contraption that uses a person’s brain waves to remotely control DNA-based nanorobots — while the nanobots were inside a living cockroach. When prompted by a human thought, the clam shell-like robots opened up, revealing a drug-like molecule that tweaked the physiology of the cockroach’s cells.

I've just done an EEG for diagnostic purposes. No cockroaches around, fortunately.

I just went up the most recent pages of this thread.

Here is a thought that came to my mind.

Lasers are perhaps not a natural part of nature, but like an electron microscope, we could be using such a tool in order to research and study nature.

Definitely true when it comes to a couple of other things as well, but are the tools being used being more important than the subjects being researched or investigated?

https://en.wikipedia.org/wiki/Nature

This link is probably better and more comprehensive, as well as coherent when compared with a couple of other similar examples.

For example that of Creation versus Genesis, which I have made a note of, but have not posted yet.

https://en.wikipedia.org/wiki/Creation

Both these things could be viewed in a similar context if the header "Religion and philosophy" is being used, as on this ambiguation page.

If rather Evolution as a subject was thought of as being a possible part of, or the reason for creation, these two things could be two different things.

This not only because of a possible personal view when it comes to a couple of things, but rather because of what one thing is supposed to be with respect to another.

I will have a little more about this later in my own thread.

There is an article by Jennifer Cobb Kreisberg published in June 1995 in "Wired News" titled "A Globe, Clothing itself with a brain" which summarizes the ideas of Pierre Teilhard de Chardin,SJ, the author of the "noosphere" concept, which predates the WWW by about 50 years. I have only a hard copy.
Teilhard de Chardin was a paleontologist, the discoverer of the Peking man whose remains were lost in the II World War, but which is searched again by Chinese scientists at Chou-Cu-Tien. He is author of several books, the most important of which is "The human phenomenon", published after his death in 1954. He is buried in New York City.

Fro "Nature" of October 6 I learn that Roger Penrose has written another book, "The emperor's new physics".. I shall have to read it. Also Carlo Rovelli has written a new book titled "Reality is not what it seems". Physics is becoming weird.

For some reason scientists start to giggle when asked "What is reality?" :)

A lifetime studying quantum mechanics has convinced Bernard d'Espagnat that the world we perceive is merely a shadow of the ultimate reality.

Another Penrose book:"Fashion, faith and phantasy in the physics of the universe", Princeton University Press. He attacks strings theory, cosmic inflation and quantum gravity. A voice out of the chorus of contemporary physics.

The film is in error when it states that Chimpanzees are man's closest relative. Our closest relative is a Bonobo. We are more closely related to Gorillas than are Chimpanzees. We do share 98% to 99% of our DNA with these species.

Some say orangutans. We are as closely related to these apes as horses are to zebras, yet act much differently by comparison. As I have posted some time ago: we were probably most like a gibbon ape that swung down from the trees about 6 million years ago and started walking upright in the grassy savannas. We ran swiftly and avoided most predators and stalked our prey, learning to use sharpened sticks and later on stone tools and spears.

So we are all Great Apes--some say not so great !!

No doubt that we humans are very close to Gorillas.

There is a tribe that still survive, William, they can be found over in Seti Politics :-))

With the remaining in science threads :-)

Physics can be very interesting.

Let's try some science. Do you really think that the speed of light is the cosmic speed limit --if so according to whom (the Observer ??). How do the photons know how fast they are moving relative to the spin and orbit of the Earth, the movement of the sun around the Galaxy and the movement among galaxies. Where is the start of the inertial plane to determine this? I claim that you could establish length as the invariable just as easily as the speed of light.. Unfortunately remember that the "observer" must depend upon light to make his determination of the time of an event.

as for the Michelson Morley experiment--please prove that the table did not contract in length. I suggest looking at the Lorentz transformations.

Of course it is.
Two reasons.
It requires an inifinitiv amount of energy to even reach the speed of light for matter and information.
If something could travel FTL it would mean that time is going backwards.
