A 2000-year-old recipe for hair dye shows Ancient Greeks and Romans used nanotechnology to permanently colour grey hair black, say experts. Dr Philippe Walter of the French state museum agency's Centre for Research and Restoration and colleagues report their findings online in the journal Nano Letters.The researchers made up a batch of dye according to a recipe used since Greco-Roman times, which includes a mixture of lead oxide and slaked lime.They soaked 50 milligrams of blond human hair in the dye for three days, then studied the hair closely. The hair turned progressively black and when the researchers took cross-sections of hair and studied it under the microscope theyfound nanocrystals of lead sulfide inside the hair shaft.
The lead in
the lead oxide had reacted with sulfur from the amino acids found in
hair keratins, the scientists say, giving the black colour.
They say the 5 nanometre
lead sulfide crystals look very much like lead sulfide quantum dots
that are made today by advanced materials science methods.
The researchers say their discovery might help develop new mineral-based nanomaterials.
Dr Ivan Kempson, a materials scientist and research fellow at the University of South Australia, is impressed with the research.
"It's the highest resolution and most detailed study of the incorporation of a metal like lead into hair," he says.
Kempson says the findings are interesting for his own work, which looks at how hair takes up metals from the environment.
But he says it is not yet clear how the sulfur in the keratin is madeavailable to interact with the lead in the hair.
Kempson says the research is also of interest to the cosmetics industry in developing hair dyes.
"If you know how they
penetrate the hair and how they react within the hair then you can
develop better cosmetic products," he says.
The research team includes a member from L'Oréal cosmetics company.
A giant figure that resembles the Roman numeral VI composed of wide trenches was discovered near the Havda village in the Kutch district of the western Indian state of Gujarat. It has evoked the curiosity of archaeologists because such signs have mostly been observed so far in Peru. Each arm of this feature is a trench that is about two meters wide, twometers deep and more than 100 meters long.Ancient scriptures claim that this area often received UFO’s from the outer space - the chariots of fire.
Archeologists suggest that the area might have been used as a spaceport by the Harappan civilization, which had one of the most fascinating yet mysterious cultures in the ancient world.Located along the Indus River in modern-day Pakistan this civilization was named after the city of Harappa and is famous for its amazing knowledge of astronomy.
Harappan
priest-astronomers closely followed the planetarymovements composing a
star-calendar that was later adopted by the Aryans.
Excavations in India had
previously shown that the ancient settlers suddenly abandoned and
re-inhabited their fortified city in the Kutch reigion several times
for reasons yet unknown. This is where the mysterious figure was found,
which may very well be the traces of an ancient spacedrome.
The meaning of the number remains a mystery.
In my book Voices from Legendary Times, I explain how many ancient sources, such as the Bible and numerous other religious and historical texts mention a time in distant past wherein giants walked the Earth.Who were these mysterious beings of great stature and incredible strength? Why and how did they disappear from the surface of this planet?Giants have often been considered legendary figures created by the ancients' imagination, representing a symbol of human power. Many scholars claim giants never existed. If that is correct, how do we explain all the giant skeletons, which have been unearthed world-wide? No, there is much more to this story. Giants were by no means fictional. Theydid exist and played a vital role in the history of mankind.
Remarkable
global archaeological evidence clearly corroborates the actual
existence of humanoid giants in prehistory.
Some scientists have
difficulties accepting the fact that giants once ruled this planet.
Confirmation of giant skeleton bones, often eight or nine feet in size,
is a threat to certain members of the scientific world. Accepting the
existence of giants is accepting that history is not as we have been
told.
Still, can we really afford
ourselves to ignore skeletons of gigantic size simply because they
conflict with our idea of evolution?
In the search for truth and
origin of man we should always be prepared to modify current scientific
theories as new discoveries are made. Unfortunately, at present times
the academic world prefers to take no noticeof fossils and artifacts,
which do not support the already established orthodox theories of human
history. Maybe this attitude will change in the future. It would
certainly be in the best interest of the public.
The pre-Adamic race
My readers are familiar
with my theory of the pre-Adamic race and the creation of the races
that once in remote times inhabitated this planet. Giants are of great
significance in the history of humanity. How far back in the distant
past can we trace the giants? The Bible tells us several interesting
things:
GENESIS 6:1-4
6:1 And it came to pass,
when men began to multiply on the face of the ground, and daughters
were born unto them, 6:2 that the sons of God saw the daughters of men
that they were fair; and they took them wives of all that they ch......
Did humanoid robots exist in the ancient Greece? Are the accounts of them purely fictional? Can they be the distant echoes of some events that took place at the dawn of modern humankind? We will not jump to conclusions. Instead, we will take a closer look at the ancient mythology from the point of view of historical retrospective.Legend has it that Hephaestus, the ancient Greek god of fire, metalworking and handicrafts, “forged” two dozen copper tripods, which could move about the place “on the golden wheels” as if they were self-propelled (or automatic?).The devices are said to have been used forrendering services to gods who visited Hephaestus.
Could they be some kind of a remote-controlled robot or automatic means of transporting?
Hephaestus had a limp, and therefore he also “forged” two maids who were made of gold.
Those maids were “strong,
sensible and could express themselves in words.” They supported
Hephaestus by the hand while accompanying him during outings, waited on
him, and amused him with their singing. They “were in possession of
every piece of knowledge taught by the immortal gods,” according to
Homer’s Iliad.
Another Greek myth says
about the “copper giant” named Thalos, which was also made by
Hephaestus. Zeus ordained that the giant should defend the island of
Crete. Thalos had an all-metal body topped with a horned head. There
was asingle artery running from top to toe of his body. The artery was
plugged with a “copper nail.” The copper giant patrolled the island,
and kept the enemy ships at bay by throwing rocks at them. He was also
a mouthpiece of Minos, a king of Crete.
Thalos began throwing “red
flame” around him after the enemy invaded Crete. Thalos managed to send
the enemies running. However, the sorceress Medea outsmarted the giant
with the help of “false visions.” Then she took the plug out of the
artery, and the giant’s black oily blood came rushing onto the ground.
As a result, Thalos’s strength thinned out. Crete became extremely
vulnerable to enemy attacks.
In terms of technology, the
following analogies fall into place if we see the story of Thalos
through the eyes of a twenty-first-century man: the “black oilybloo......
