Graphene is both the thinnest and the strongest material yet discovered, opening up new frontiers in quantum physics. Two Russian scientists have been awarded the Nobel Prize for Physics for their work developing graphene.

 Andrei Geim and Konstantin Novoselov demonstrated that carbon in its extremely thin form – just one atom thick – had exceptional properties originating in the world of quantum physics.

Konstantin Novoselov is a Royal Society Research Fellow at the University of Manchester in their Mesoscopic Research Group researching mesoscopic systems and nanostructures. He was awarded the 2008 Europhysics Prize for the same discovery.

Andre Geim is a physicist who, as well as the discovery of graphene, is known for the development of gecko tape and demonstrations of diamagnetic levitation. He’s also based at the University of Manchester.

Graphene is both the thinnest and the strongest material yet discovered. Geim and Novoselov extracted it from ordinary graphite, and used ordinary adhesive tape to obtain a flake of carbon with a thickness of just one atom.

“Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics,” says the Royal Swedish Academy of Sciences.

“A vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers.”

It is said that investments in Graphene will reap huge dividends.

Cancer: Man’s Own Doing?

Blood runs through our veins

In modern day living Cancer is the bane.

When young I had often wonder why the study of archaeology or anthropology. I just couldn’t visualise the benefits to the living human. Directly or indirectly, they have much relevance & reveal hidden knowledge to the medical field. For instance, archaeology & the study of Egypt mummies have proved that cancer was extremely rare in ancient times.

Leading medical researchers are led to conclude from archaeological findings that cancer is a relatively modern disease, brought on by our lifestyle & diet – being most endemic in industrialised societies. Could this be conclusive?

US-based writer & investigator Terrence Aym’s article on “Egyptian Mummies Prove Cancer Is Man-Made” claims that while “cancer kills millions of people annually . . . the strange fact is that there is no trace of the insidious killer among the remains of ancient peoples”.

Professor Michael Zimmerman, the US biologist, recently declared in an interview with a British newspaper, “In an ancient society lacking surgical intervention, evidence of cancer should remain in all cases”. However, in a study of the Egyptian mummies, it simply does not exist. Zimmerman concluded “The virtual absence of malignancies in mummies must be interpreted as indicating their rarity in antiquity, indicating that cancer-causing factors are limited to societies affected by modern industrialisation”.

Zimmerman’s colleague, Professor David, spoke at a conference in early 2010. During her presentation she stated that, “In industrialised societies, cancer is second only to cardiovascular disease as a cause of death. But in ancient times, it was extremely rare.

”There is nothing in the natural environment that can cause cancer,” she noted. “So it has to be a man-made disease, down to pollution and changes to our diet and lifestyle.”

Perhaps all this new evidence should make the US FDA reconsider artificial sweeteners, binders, and preservatives not to mention irradiated food, genetically engineered crops and animals and the newly approved cloning?

For some years many cancer experts have contended that the modern-day malady must have its roots in the modern-day lifestyle, particularly that of the Western culture. The mute mummies have actually communicated a lot: their bodies’ lack of cancers and tumours underscore many researchers’ suspicions and tend to support their theories. 

Not content to let physical evidence alone prove the case that cancer is man-made, Zimmerman and an associate, Rosalie David, poured through ancient literature, classical medical writings and investigated fossil records likely to contain the tell-tale signs of encroaching carcinoma but to no significance.

A previous study of thousands of bones from the remains of Neanderthals also failed to turn up evidence of any cancers. According to the study, only one Neanderthal may have been afflicted with cancer, and even that is not proven

Although the ancient Greeks were the first to write of diseases that today would be identified as forms of cancer, the condition was exceedingly rare. It was not until the middle of the 17th Century that medical texts began defining the disease which had suddenly become more prevalent.

Zimmerman asserts that his research shows that distinctive tumours, carcinomas and cancerous lesions only began to be seen about 200 years ago. That falls in line with the beginning of the Industrial Revolution and the introduction of pollutants into the air and water and the addition of chemicals with artificial processing of of foods to preserve them longer than traditional methods of salting, smoking or drying.

Evidences point that an unhealthy lifestyle, smoking, pollution, obesity stress, tension and bad eating habits have made what used to be a relatively rare disease far more widespread. We may thus conclude that wile cancer though may not be entirely man-made, but the hand of humankind in its propagation is very clearly visible.

My brother-in-law recently passed on at age 64 of lung cancer. He was a non-smoker. I believe it’s the polluted environment of Taipei where he lived that contributed to his cancer, which was only detected in the fourth stage – just too advanced for any cure. People say the good die young. At 64, with the advancement of modern medical science, he was indeed young to have passed on.
