Nobel Laureates of 2009

Filed under: Nobel Prize — Tags: — Winson @ 8:34 AM

The Nobel Prizes are universally regarded as the most prestigious and renowned awards given for intellectual performance in the world. The Nobel Foundation started in 1900 based on the will and testament of Alfred Nobel written on 27th November 1895. As per his wish, the award should be given to those who make outstanding contributions to the mankind in the five areas, Physics, Chemistry, Medicine or Physiology, Literature, and Peace, while Economics category added later in 1968.

Nobel Prize in Physics
Nobel Prize in physics for 2009 was awarded to three people. Charles K. Kao of china was awarded half of prize for his innovative achievements dealing with the transmission of light in fibers for optical communication. Willard S. Boyle and George E. Smith of USA shared remaining half value of prize equally for the discovery of CCD sensor, an imaging semiconductor circuit.

In 1966, Charles K. Kao carefully worked on how to transmit light covering long distances through optical glass fibers. He discovered that fiber of purest glass can transmit light signals over 100 kilometers which was an innovation in fiber optics technology.

In 1969 Willard S. Boyle and George E. Smith discovered the first outstanding imaging technology using a digital sensor, a CCD. The CCD is a digital camera’s electronic eye which revolutionized the way how images were gathered from spacecraft, by telescopes, in medical imaging, and finally replaced the film camera in whole aspects of photography.

Nobel Prize in Chemistry
Nobel Prize in chemistry for 2009 was awarded jointly to Venkatraman Ramakrishnan of United Kingdom, Thomas A. Steitz of USA and Ada E. Yonath of Israel for their research on the structure and function of the ribosome.

Three scientists created atom-by-atom maps of the hidden, life-giving ribosome which helped researchers to develop powerful new antibiotics. They used three-dimensional models to illustrate how antibiotics attaches to the ribosome. These models are used to develop new antibiotics, depending on the interpretation of the molecular structure and framework of the ribosomes in every cell.

Nobel Prize in Medicine
The Nobel Prize in Medicine for 2009 was shared by Elizabeth H. Blackburn, Carol W. Greider, Jack W. Szostak of USA. It was awarded for the discovery of how chromosomes are guarded by telomeres and the enzyme telomerase.

They discovered telomeres which are created in the reproduction sequences of DNA at the ends of chromosomes that helps in protecting the purity of the chromosomal DNA, and discovered the enzyme telomerase which builds the telomeres.

Their work revealed some of the basic secrets about functioning of cells. Their studies were also applicable to cancer biology as cancer cells have excessively active telomerase, which makes them to divide uncontrollably.

Nobel Prize in Literature
The 2009 Nobel Prize in Literature was awarded to Herta Müller of Germany. She is the 12th woman in 108 years to receive Nobel prize for literature. Mueller, a representative of Romania’s ethnic German minority, was honored for her work as described by Nobel foundation “with the concentration of poetry and the frankness of prose, depicts the landscape of the dispossessed,”

Nobel Peace Prize
The Nobel Peace Prize for 2009 was awarded to Barack H. Obama who is the 44th President of the United States of America for his outstanding efforts to establish international diplomacy and cooperation between people. The Committee also gave special significance to Obama’s vision and his work for a world without nuclear weapons. After this announcement, some people raised their concern that the decision had come too early, before any significant achievements were made in his foreign policy. Whereas many world leaders were supportive of the award. Some raised their concern that the prize was awarded to encourage the US leader early in his presidency.

Nobel Prize in Economics
The Nobel Prize in Economics for 2009 was awarded jointly to Elinor Ostrom and Oliver E. Williamson of USA. It was awarded to Elinor Ostrom for her studies on economic governance, mainly in the commons and to Oliver E. Williamson for his studies on economic governance, particularly in an organization.

Elinor Ostrom was the first woman to win a Nobel Prize in economics. Ostrom showed how common resources like forests, fisheries, oil fields or grazing lands can be managed well by the people who use them, instead of governments or private companies.

Williamson, focused on how firms and markets differ in the methods they solve conflicts. He found that companies can resolve conflicts better than markets when competition is fixed.

Nobel Prize in Physiology or Medicine 2009

Filed under: 2009,Nobel Prize — Tags: — Winson @ 2:47 AM

The 2009 Nobel Prize for Medicine has been awarded to researchers Elizabeth Blackburn, Carol Greider, and Jack Szostak for studying the way chromosomes are protected and for discovering the ‘immortality enzyme’ telomerase. The research could have ample implications on diseases such as cancer and other age related conditions. In keeping with the Nobel tradition, the Nobel Prize for medicine has been awarded first. The Nobel laureates shared a $1.4 million purse and a diploma, along with an invitation to the prize ceremonies to be held at Stockholm. For the first time in history, two women shared the Nobel Prize in medicine.

The scientists have been honored for their study of the way chromosomes are protected by the cap like telomeres and their discovery of the enzyme telomerase that allows cells to divide incessantly without dying. Telomeres are cap like structures at the tail end of the chromosomes that are bestowed with a unique DNA sequence that prevents their deterioration. The telomeres also act as deterrents to chromosomal rearrangement which may itself result in abnormalities. Telomeres are lost with each cell division exposing the chromosomes to unfavorable possibilities like cancer and aging. Blackburn and Szostak strived to explain that the unique DNA sequence in the telomeres protects the chromosomes from deterioration while Carol Greider and Blackburn identified the enzyme telomerase that replenishes or helps to rebuild the lost sequences of the telomeres. Cells age when the cap like telomeres are shortened. However, on the other hand, if the activity of the telomerase enzyme is sufficient enough telomere deterioration can be controlled and aging thwarted. Blackburn’s discovery proved the fact that stress has a definite impact on telomere reduction thus strengthening the mind body connection. Though increased telomere activity could ward off aging for a while it also increases a person’s risk to ward off cancer. This means that the steady shortening of the telomeres and the accompanying decreased telomerase activity is believed to be a process that is inbuilt in man as a survival mechanism.

Nobel Prize in Physics 2009

Filed under: Nobel Prize — Tags: — Winson @ 2:50 AM

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2009 with one half of the $1.4 million to Charles K. Kao, Standard Telecommunications Laboratories, Harlow, UK and Chinese University of Hong Kong, “for their groundbreaking achievements concerning the transmission of light in fibers for optical communication”. The other half of the prize jointly to Willard S. Boyle and George E. Smith, Bell Laboratories, Murray Hill, NJ, USA “for the invention of an imaging semiconductor circuit – the CCD sensor.”

It was in 1966, when Charles K. Kao made a discovery that led to a breakthrough in fiber optics, which involved the careful calculation of how to transmit light over long distances via optical glass fibers. Kao presented his research at the 1966 London meeting of the Institution of Electrical Engineers. Then the first ultra pure fiber was successfully fabricated four years later by the Corning Company.

In 1969, Willard S. Boyle and George E. Smith invented the first successful imaging technology using a digital sensor, a CCD (charge-coupled device). The two came up with the idea in just an hour of brainstorming. According to Boyle, the biggest achievement of his work was seeing images transmitted back from Mars. The CCD technology makes use of the photoelectric effect as was theorized by Albert Einstein. By this effect, light is transformed into electric signals and the challenge lies in gathering and reading out the signals in a large number of image points in a short time. The CCD is the digital camera’s electronic eye which revolutionized the way images were collected from spacecraft, by telescopes and in medical imaging, and has eventually replaced the film camera in every field of photography.

Nobel Prize in Chemistry 2009

Filed under: 2009,Nobel Prize — Tags: — Winson @ 2:52 AM

The Nobel Prize in Chemistry 2009 was given to three scientists who produced atom-by-atom maps of the mysterious, life giving ribosome that allows researchers to produce powerful new antibiotics. The ribosome present in the DNA translates the information in the DNA to life. Ada Yonath from Israel and US scientists Venkatraman Ramakrishnan and Thomas Steitz shared the 10 million Swedish crown (US$1.4 million) prize for showing how the ribosome operates at the atomic level. According to the Nobel Committee for Chemistry at the Royal Swedish Academy of Sciences, since ribosomes are crucial to life, they are major target for new antibiotics.

A method known as X-Ray crystallography was used to pinpoint each of the hundreds of thousands of atoms present in the ribosome. The technique involves impinging X-rays at a crystal. The rays are scattered when they impinge on the atoms and by looking at how they spread out, scientists can determine where atoms are positioned. Yonath was the first person to research into this area when she first tried the method on the ribosome. She began by taking a microorganism found in the nearby Dead Sea and crystallizing its ribosomes by freezing them at nearly minus 200 degree Celsius. But it took another 20 years before a full map was made. The three scientists arrived to the same conclusion almost simultaneously in 2000, publishing crystal structures that were sharply enough defined to locate atoms. The research has vast implications in the field of medicine, since fifty percent of all antibiotics target the ribosome, this finding can lead to the development of other substances that can block and disturb bacteria in our bodies.

Nobel Prize in Literature 2009

Filed under: 2009,Nobel Prize — Tags: — Winson @ 2:53 AM

German novelist, Herta Muller has become the 12th woman in 108 years to win the Nobel Prize for literature. She was praised by the Nobel judges for depicting the landscape of the dispossessed with the concentration of poetry and frankness of prose. Muller constantly returns to the oppression, dictatorship, and exile of her own life in her novels, essays, and poems. Worth 10 million Swedish kronor the Nobel is awarded to “the person who shall have produced in the field of literature the most outstanding work in an ideal direction”, as described in Alfred Nobel’s will of 1895.

According to the permanent secretary of the Swedish Academy, Peter Englund, Muller had the capacity of really giving you the sense of what it was to live in a dictatorship, to be as a minority in another country and to live in exile. Muller has a very fine tuned precision in her language.

Born in Romania in 1953, Muller rejected to work together with Ceausescu’s Securitate, lost her job as a teacher, and was a subject of repeated threats until she emigrated in 1987. She now lives in Berlin, where she has received a multitude of literary awards, including Germany’s most prestigious, the Kleist prize, the Frankz Kafka, and the 100,000 Euro Impac award for Hertzier.
