London: Using new nanotechnology, researchers have reproduced a colour image of Mona Lisa which is less than one pixel on an iPhone Retina display – 50 micrometres long or about 10,000 times smaller than the real Mona Lisa in the Louvre Museum in Paris.

The breakthrough revolutionises laser printing technology, allowing people to print high-resolution data and colour images of unprecedented quality and microscopic dimensions.

The new laser technology allows printing in a mind-blowing resolution of 127,000 dots per inch (DPI). In comparison, weekly or monthly magazines are normally printed in a resolution equivalent to 300 DPI.

The team from Technical University of Denmark (DTU) believe that there is considerable scope for application of the new laser printing technology.

“It will be possible to save data invisible to the naked eye. This includes serial numbers or bar codes of products and other information. The technology can also be used to combat fraud and forgery as it will be easier to determine whether the product is an original or a copy, ” explained professor Anders Kristensen from DTU Nanotech.

Printing the microscopic images requires a special nanoscale-structured surface.

The structure consists of rows with small columns with a diameter of merely 100 nanometers each.

This structured surface is then covered by 20 nanometers of aluminium.

When a laser pulse is transmitted from nanocolumn to nanocolumn, the nanocolumn is heated locally, after which it melts and is deformed.

The temperature can reach up to 1,500 degrees Celcius but only for a few nanoseconds, preventing the extreme heat from spreading.

Strong laser pulses create a drastic deformation, which gives the reflection from the nanocolumn an orange and yellow colour tone.

The new laser printing technology can also be used on a larger scale to personify products such as mobile phones with unique decorations, names, etc.

Foreign companies producing parts for cars, such as instrument panels and buttons, are already taking a keen interest in the technology as it can simplify the production.

The breakthrough in nanotechnology was detailed in the journal Nature Nanotechnology. (IANS) (image courtesy: animalnewyork.com)

Transforming Human Race: Human to TransHuman to PostHuman

Is it good to become transhuman and extend life and capabilities beyond normal or it is something which will finally destroy us?

  • A Trans-human is someone who is human, to begin with, but then with the help of technology enhances his capabilities
  • Human Race is changing at very fast pace

Have you ever paid attention to the fact that humans are slowly becoming machines? The number of mechanical and electrical devices, in the human body, are increasing at a fast pace. Even parents of a child need not be humans. They can be agencies, trust, bodies, department etc.

First of all. Lets us figure out, who is a human? Any idea? Think for a minute. What makes us human? Is it our genes, our thinking capabilities, our consciousness, spirituality, physical abilities, look, our erect posture, ability to walk on feet, or something else? As per Merriam Webster dictionary, a human is a bipedal primate mammal.

An extreme form of the transhuman is called posthuman. Wikimedia Commons

What is a Transhuman?

A transhuman is someone who is human, to begin with, but then with the help of technology enhances his capabilities, which are way more than a normal human. Means more intelligence, psychological capability, strength or physical stamina. There is either extension of life, improved quality of life or more capabilities or all of these. An extreme form of the transhuman is called posthuman. Posthuman is a being made up of artificial parts, with minimal or no human attributes remaining.

In stories or fiction, this type of human is called Cyborg or Bionic human or a genetically enhanced human.

Change from human to trans human can be achieved by various mechanical or electrical devices, Gene therapy, Artificial intelligence, Nanotechnology, Genetic engineering, Cloning etc. Are you aware that technology is being developed to upload the mind to a computer and print human organs?

Following are the examples of some artificial things which change humans to Transhumans:

Bionic eyes or visual prosthesis

Intraocular lenses/Contact lenses

Artificial voice box

Artificial limbs

Nails/pins in bones

Artificial knees/hips

Neurostimulators

Penile prosthesis

Artificial heart

Artificial heart valves

Pacemakers

Defibrillators

Ventricular assist devices

Transcranial direct current stimulation

Powered exoskeletons

Ear chips etc.

So, what are your thoughts? Is it good to become transhuman and extend life and capabilities beyond normal or it is something which will finally destroy us.

How arrogant will we be if we become eternal? Will there be a population explosion on planet earth? Will we still be eating food and reproducing? What about natural resources? Will there be a need to inhabit other planets? What will happen if we all are very high tech and have equal IQ? Who will rule us? How are we going to interact with each other? Will there still be feelings left? Will we still seek eternal happiness?

So, the basic question is what do you prefer? Stay as a human? Or become a transhuman or posthuman? Or something in the middle? And what is that middle? Where will you stop?

Do share your opinion!
