Experts create invisibility cloak
By Paul Rincon Science reporter, BBC News |
A US-British team of scientists has successfully tested a cloak of invisibility in the laboratory.
The device mostly hid a small copper cylinder from microwaves in tests at Duke University, North Carolina.
It works by deflecting the microwaves around the object and restoring them on the other side, as if they had passed through empty space.
But making an object vanish before a person's eyes is still the stuff of science fiction - for now.
The cloak consists of 10 fibreglass rings covered with copper elements and is classed as a "metamaterial" - an artificial composite that can be engineered to produce a desired change in the direction of electromagnetic waves.
Like visible light waves, microwaves bounce off objects, making them apparent and creating a shadow. But at microwave frequencies, the detection has to be made by instruments rather than the naked eye.
New chapter
Water behaves differently. When water in a river flows around a smooth rock, the water closes up on the opposite side. Someone looking at the water downstream would never guess it had passed around an obstacle.
The metamaterial cloak channelled the microwaves around the object like water flows around the rock.
"These metamaterials have opened a new chapter in electromagnetism. We've opened the door into the secret garden," co-author Professor John Pendry, from Imperial College London, told BBC News.
In the experiment, the scientists first measured microwaves travelling across a plane of view with no obstacles. Then they placed a copper cylinder in the same plane and measured the disturbance, or scattering, in the microwaves.
Next, the researchers placed the invisibility cloak over the copper cylinder. The cloak did not completely iron out the disturbance, but it greatly reduced the microwaves being blocked or deflected.
Hidden from view
"This cloak guides electromagnetic waves around a central region so that any object at all can be placed in that region and will not disturb the electromagnetic fields," explained co-author Dr David Schurig from Duke University.
"There is reduced reflection from the object, and there is also reduced shadow."
In principle, the same theoretical blueprint could be used to cloak objects from visible light. But this would require much more intricate and tiny metamaterial structures, which scientists have yet to devise.
"As an application, it's not clear that you're going to get the invisibility that everyone thinks about - as in Harry Potter's cloak, or the Star Trek cloaking device," said Professor David R Smith of Duke.
Broad applications
John Pendry commented: "There's a rule about the internal structure of the metamaterial: it has to be smaller than the wavelength of radiation. So for radar waves that's 3cm. You can easily engineer something a few millimetres across.
"You go up to optical radiation - visible light - and the wavelength is less than a micron. So your microstructure has to be a few tens of nanometres across. and we're only just learning how to do nanotechnology... maybe in five or 10 years' time you could do this, but not today."
The researchers say that if an object can be hidden from microwaves, it can be hidden from radar - a possibility that will ensure interest from the military.
Professor Pendry said a metamaterial cloak could be manufactured to wrap around a fighter plane or tank. But, he said: "You mustn't demand that the cloak be too thin. Despite the hype around Harry Potter, this isn't anything that flaps around in the breeze; it's more like a shed."
It could be used to hide objects from terahertz waves, a regime that is being exploited for numerous sensing technologies, or even from mobile phone frequencies and magnetic fields.

Alfred Nobel and the prize that almost didn’t happen
The Nobel prizes for this year will be announced all throughout October
No more than three individuals can win in any science category. The system to choose Nobel medical prize laureates is costly. Dr Jornvall, the Nobel Foundation official, said about $700,000 is spent for the research into the medical prize, now worth about $1.4 million.
WHEN Alfred Nobel, the Swedish inventor of dynamite and more powerful explosives, died in 1896, he bequeathed the bulk of his fortune to create five annual prizes honouring ingenuity. The chemistry, medicine and physics prizes have come to be widely regarded as the most esteemed in their fields. The two others, literature and peace, are more controversial.
Yet in a little known story, the Nobel Prizes, almost never came to be, largely because of the unsophisticated way Nobel drew up his will. It was flawed and legally deficient because he lived in many places and never established a legal residence. Nobel resided for many years in France, made intermittent visits to a home in Sweden and amassed assets in many countries before dying of a stroke at his villa in Italy.
To secret Nobel’s French assets to the Swedish consulate in Paris before claims might be made on them there, the will’s principal executor literally sat on Nobel’s millions as he rode a horse-drawn cab through Paris. “I sat with a revolver at the ready in case of a direct attack or a prearranged collision with another vehicle, a trick not unusual among thieves in Paris at the time,” the executor, Ragnar Sohlman, wrote in “The Legacy of Alfred Nobel,” which was published in English in 1983.
Large philanthropic gifts to science were rare in Nobel’s day. Moreover, establishing annual international prizes in any field was novel. And controversial. News of Nobel’s plan sent shockwaves through Sweden with the intensity of a dynamite blast.
Bitter members of Nobel’s largely disinherited family fought the will in court. Scorn was heaped on Nobel’s gift, the equivalent of $9.5 million and one of the largest fortunes of his time, by the king of Sweden, Oscar II; newspapers; political leaders; and other Swedes.
Nobel’s earnings came from his 355 patents and factories in many countries. Swedish leaders vehemently opposed dispersing a Swedish fortune to the rest of the world. Among their reasons: it was immoral, particularly at a time when many Swedes were impoverished.
King Oscar II changed his mind after the Nobel Foundation was established in 1900, in part because he thought publicity about the prizes might benefit Sweden. He was too ill to attend the first ceremony in 1901, said Dr Hans Jornvall, an official at the Nobel Foundation. Starting in 1902, Oscar II and his royal successors have handed the prizes to the laureates on December 10, the anniversary of Nobel’s death.
Nobel said in his will that he wanted to reward those “who during the preceding year shall have conferred the greatest benefit on mankind” in five categories.
Beyond the honour bestowed on the winners, the science prizes focus worldwide attention on important discoveries, including many that have shaped the practice of medicine and the course of research.
Many doctors and scientists develop a fascination with the Nobels in graduate school, if not earlier, in part because of the Nobel Foundation’s reputation for a secretive process that rivals the Vatican’s. But few know the history of the prizes.
My view of the prizes comes from a number of vantage points. I have covered the medical prizes over the last 35 years, worked in a hospital in Stockholm in the ’70s and wrote about the Swedish health system. While there, I discussed the workings of the prize system with officials of the Nobel Foundation and members of the Nobel Assembly, which votes on the award committee’s recommendations for each year’s prizes.
My impression is that Nobel officials do not like controversy associated with the prizes, which partly explains Nobel rules forbidding appeals by the losers. Votes for winners are announced as unanimous. But I heard behind-the-scenes tales that the path to that final vote for some awards has been strewn with fights among clinicians, basic scientists and others involved in the process.
Nevertheless, the extensive effort that goes into researching the nominees each year maintains the integrity of the prizes. And the nominations inform Swedish doctors about the cutting edge of science, keeping Sweden, a country of eight million people, atop world science.
Nobel was born in Sweden, and his father, an engineer, moved his family to St Petersburg, Russia, when Alfred was nine. His education was largely through Russian tutors. He became fluent in a number of languages, and as he went on to travel the world and his wealth increased, Nobel became known as the richest vagabond in Europe.
In the early ’60s, Nobel began experimenting with nitroglycerin and other explosives in a laboratory at his father’s home. But in 1864, his younger brother, Emil, and four others were killed in a laboratory accident.
Despite the tragedy, Nobel persisted. For example, in Manhattan in May 1866, Nobel demonstrated the explosive effects and safety of nitroglycerin, when properly handled, on a rocky slope at 83rd Street, between Eighth and Ninth Avenues.
In 1867, Nobel accidentally discovered that when nitroglycerin dripped on kieselguhr, a silicon-containing earth, it formed a paste that was stable and safer to use than liquid nitroglycerin alone. Nobel called it dynamite, patented it and began building factories to make it in Europe.
Nobel was ill much of his life, experiencing migraine headaches, bouts of deep depression and, in his last few years, the chest pains of angina from blocked coronary arteries. “Isn’t it the irony of fate that I have been prescribed nitroglycerin to be taken internally” and by another name to disguise its contents, Nobel wrote to Mr Sohlman, his chief executor.
Nobel wrote his will in Swedish a year before his death while he lived in Paris, and the portion dealing with the prizes was one long paragraph. It named the groups to make the awards: the Karolinska Institute (medicine), the Swedish Academy of Sciences (chemistry and physics), the Swedish Academy (literature) and the Norwegian Parliament (peace). Later, economics was added as a separate prize.
Nobel never explained his choice of prize categories. Chemistry and physics seem obvious choices because he was a trained chemical engineer.
The medical prize appears to reflect his heritage and interests. A 17th-century ancestor, Olof Rudbeck the Elder, a professor of medicine at Uppsala University, was a discoverer of the human lymphatic system. With other researchers, Nobel discussed experiments in blood transfusions. While alive, he gave generously for research at the Karolinska Institute and at Ivan Pavlov’s laboratory in Russia.
Nobel often relieved his depression by writing fiction, drama and poetry, which probably explains his interest in the literature prize.
The reason for the peace prize is less clear. Many say it was to compensate for developing destructive forces. But his explosives, except for ballistite, were not used in any war during his lifetime, Tore Frangsmyr wrote in a portrait of Nobel published by the Swedish Institute in Stockholm in 1996.
More important, dynamite helped in mining, digging canals, making roads, building the St Gotthard tunnel through the Alps between Italy and Switzerland, and completing other construction projects. According to Mr Frangsmyr, Nobel said his factories would put an end to war more quickly than peace conferences because “when two armies of equal strength can annihilate each other in an instant, then all civilized nations will retreat and disband their troops.”
Nobel was unhappy in love, never married and described himself as a loner. Mr Sohlman wrote that when one of Nobel’s brothers asked for a biographical note, Nobel said about himself: “Alfred Nobel — a pitiful half-life which ought to have been extinguished by some compassionate doctor as the infant yelled its way into the world.”
Mr Frangsmyr wrote that Nobel once described himself as a well intended misanthrope: “I’ve got a mass of screws loose and am a superidealist who can digest philosophy better than food.”
Swedes were astonished that Nobel prepared his will unaided and without consulting the executors of his estate and the institutions that he entrusted to make the awards. He even left his fortune to a nonexistent foundation that his executors had to create posthumously.
Nobel’s disregard for legal advice in writing his will reflects what he wrote in dealing with a legal matter, according to Mr Sohlman: “Lawyers have to make a living, and can only do so by inducing people to believe that a straight line is crooked.”
Mr Sohlman had to persuade the Swedish institutions to overcome many objections before agreeing to administer the prizes. The new demand was costly and added to the workload of academicians whose salaries were meager. No blueprint existed to guide the prize juries. Sweden had produced leading scientists, but insecurity existed about whether a small group of scientists in a small country could effectively judge claims for the discoveries made worldwide.
If any institution that Nobel named in his will rejected his charge, there probably would be no prizes. But by 1900, Mr Sohlman had gained their cooperation.
The Karolinska Institute decided to primarily reward fundamental biomedical research, not clinical research. That action is credited for linking medicine to the emerging wave of laboratory science illustrated, for example, by Louis Pasteur, a chemist and bacteriologist. Pasteur, who died the year Nobel wrote his will, was ineligible for a prize because the Nobels are not awarded posthumously.
There were many competitors for the first awards, which went to well-recognized scientists: a German, Emil von Behring, for developing a diphtheria immunization; a German, Wilhelm Konrad Roentgen, in physics for the discovery of X-rays; and a Dutchman, Jacobus H. van’t Hoff, for discovering the laws of chemical dynamics and osmotic pressure in solutions.
No more than three individuals can win in any science category. The system to choose Nobel medical prize laureates is costly. Dr Jornvall, the Nobel Foundation official, said about $700,000 is spent for the research into the medical prize, now worth about $1.4 million.
The winners are announced in October. But the nomination process for the next year’s prizes begins a month earlier. The Karolinska Institute asks 3,000 scientists and administrators to nominate by January 31 researchers who they believe have made the most prize-worthy discovery for consideration in that year’s competition.
The awards honour a discovery, not career achievements. Nominators may propose any number of candidates, “but if they suggest too many, they dilute their own strength,” Dr Jornvall said.
In the following months, an awards committee screens the nominees and does extensive homework on the most promising ones. A fresh group of nominees is considered each year because even candidates who were finalists in one year must be nominated again to be eligible for the prize in another year.
Many say the committees have stumbled a few times in choosing winners and omitting others. The names depend on the critic.
Honouring Dr Egas Moniz of Portugal with a Nobel in 1949 for discovering the therapeutic value of a lobotomy in certain psychoses is perhaps the most egregious mistake ever made by a prestigious biomedical awards committee.
Years before the prize, lobotomies had been performed on a number of patients, including John F. Kennedy’s sister, Rosemary. The prestige of the Nobel Prize accelerated the use of lobotomies, including among famous hospitals in many countries. The procedure proved worthless.
Two other dubious awards were made in successive years: those in 1926 to a Dane, Johannes Fibiger, for a misleading discovery about cancer and in 1927 to an Austrian, Dr Julius Wagner-Jauregg, for discovering that injecting malaria parasites had value in treating syphilis affecting the brain. The treatment did not work and could be dangerous.
These and other experiences made the Nobel committees more cautious in meeting Nobel’s charge to honour a discovery made during the preceding year. The committees have learned that validating a discovery can take many years.
Now Nobel committees are criticised for the long delays, often decades, between a discovery and the award. It took more than 50 years for Peyton Rous to be honoured for discovering cancer-causing viruses.
Critics also cite many scientists who they believe should have won a Nobel. Among those often mentioned are Dr Herbert W. Boyer and Dr. Stanley N. Cohen. In the early ’70s, they developed the cloning technique that underlies genetic engineering and the development of a number of new tests and drugs.
Public health workers feel that a Nobel Prize should have been awarded for eradicating smallpox, the only naturally occurring disease to be wiped out. Dr. Hans Wigzell, a former rector of the Karolinska Institute, has told me that even such a monumental success does not qualify as a discovery if it relies on an old technique. Smallpox eradication is owed to a vaccine developed by Edward Jenner in the late 1700’s.
The opinions collected over the last 105 years have made the Nobel archives a trove of information about the history of 20th-century science. So in response to many people who wanted to use that information, the Nobel Foundation amended the original statutes, which called for eternal secrecy, to allow qualified individuals to examine the archives 50 years after an award. Some of the information is posted in English on the foundation’s website (nobelprize.org).
Michael Bliss, emeritus professor of history at the University of Toronto, was one of the first people to examine the archives, in 1981, for his book The Discovery of Insulin.
The records, mainly in Swedish, were “very thorough,” he said in an interview, and “for comic relief, for each year there was a thick box labeled self-nominations,” which are ineligible.
Politics can play a role in selecting prize winners. Professor Bliss said that in his review of the Nobel documents, “you could see how people would carry on campaigns on behalf of certain people, getting others to write supporting letters and so on.”
The Nobels have spawned the creation of scores of other science awards. Many newer ones measure their success in part by the number of their winners who later become Nobel laureates.
Universities and research centres, too, publicise the number of Nobel winners they have produced or hired.
Nobel winners are selected for their discoveries, not their IQs, and most are not geniuses, said one Nobel laureate, Dr. Michael S. Brown of the University of Texas Southwestern Medical Centre in Dallas.
Illustrating his point with a humorous anecdote, Dr Brown recalled a moment when laureates met in Stockholm at the centennial of the Nobel Prizes: “If you really want to know what Nobel Prize winners are like, you should have been in the breakfast line seeing all these brilliant people wandering around randomly trying to find the scrambled eggs. It was like anything but a group of brilliant folks.” — Dawn/The New York Times

Shared grief is half the sorrow, but happiness when shared, is doubled.
One man was allowed to sit up in his bed for an hour each afternoon to help drain the fluid from his lungs.
His bed was next to the room's only window.
The other man had to spend all his time flat on his back.
The men talked for hours on end. They spoke of their wives and families, their homes, their jobs, their involvement in the military service, where they had been on vacation.
Every afternoon when the man in the bed by the window could sit up, he would pass the time by describing to his roommate all the things he could see outside the window.
The man in the other bed began to live for those one hour periods where his world would be broadened and enlivened by all the activity and color of the world outside.
The window overlooked a park with a lovely lake. Ducks and swans played on the water while children sailed their model boats. Young lovers walked arm in arm amidst flowers of every color and a fine view of the city skyline could be seen in the distance.
As the man by the window described all this in exquisite detail, the man on the other side of the room would close his eyes and imagine the picturesque scene.
One warm afternoon the man by the window described a parade passing by.
Although the other man couldn't hear the band - he could see it. In his mind's eye as the gentleman by the window portrayed it with descriptive words.
Days and weeks passed.
One morning, the day nurse arrived to bring water for their baths only to find the lifeless body of the man by the window, who had died peacefully in his sleep. She was saddened and called the hospital attendants to take the body away.
As soon as it seemed appropriate, the other man asked if he could be moved next to the window. The nurse was happy to make the switch, and after making sure he was comfortable, she left him alone.
Slowly, painfully, he propped himself up on one elbow to take his first look at the real world outside. He strained to slowly turn to look out the window beside the bed.
It faced a blank wall.
The man asked the nurse what could have compelled his deceased roommate who had described such wonderful things outside this window.
The nurse responded that the man was blind and could not even see the wall.
She said, "Perhaps he just wanted to encourage you."
Epilogue:
There is tremendous happiness in making others happy, despite our own situations.
Shared grief is half the sorrow, but happiness when shared, is doubled.
If you want to feel rich, just count all the things you have that money can't buy.
