Muslim world especially Middle East and surrounding regions, where we live, are facing some of the worst political turmoil of our history. We are seeing wars, terrorism, refugee crisis and resulting economic. The toughest calamities are faced by common people who have very little or no control over the policies which are resulting in the current mess. Worst thing which is happening is the exploitation of sectarianism as a tool to forward foreign policy and strategic agenda. Muslims in many parts of the world are criticizing western powers for this situation but we also need to seriously do some soul searching.
We need to see why are we in this mess?
For me one major reason is that OIC members have failed to find enough common constructive goals to bring their people together.
After the Second World War, Europe realized the importance of academic and economic cooperation for promoting peace and stability. CERN is a prime example of how formal foes can join hands for the purpose of discovery and innovation.
France and Germany have established common institutes and their universities regularly conduct joint research projects. UK and USA, despite enormous bloodshed the historical American war of independence, enjoy exemplary people to people relationships and academic collaboration is a major part of it. It is this attitude of thinking big, finding common constructive goals and strong academic collaboration, which has put them in the forefront of science and technology.
Over the last few decades, humanity has sent probes like Voyager which are challenging the limits of our solar system, countries are thinking about colonizing Mars, satellites like PLANCK and WMAP are tracking radiation from the early stages of our universe, quantum computing is now looking like a possibility and projects are being made for hyper-sonic flights. But in most of the so called Muslim world, we are stuck with centuries old and good for nothing sectarian issues.
Despite some efforts in the defense sector, OIC member countries largely lack the technology base to independently produce jets, automobiles, advanced electronics, precision instruments and many other things which are being produced by public or independent private sector companies in USA, China, Russia, Japan and Europe. Most of the things which are being indigenously produced by OIC countries rely heavily on foreign core components like engine or high precision electronics items. This is due to our lack of investment on fundamental research especially Physics.
OIC countries like Turkey, Pakistan, Malaysia, Iran, Saudi Arabia and some others have some basic infrastructure on which they can build upon to conduct research projects and joint ventures in areas like sending space probes, ground based optical and radio astronomy, particle physics, climate change and development of strong industrial technology base. All we need is the will to start joint projects and promote knowledge sharing via exchange of researchers or joint academic and industrial research projects.
These joint projects will not only be helpful in enhancing people to people contacts and improving academic research standards but they will also contribute positively in the overall progress of humanity. It is a great loss for humanity as a whole that a civilization, which once led the efforts to develop astronomy, medicine and other key areas of science, is not making any or making very little contribution in advancing our understanding of the universe.
The situation is bad and if we look at Syria, Afghanistan, Iraq, Yemen or Libya then it seems we have hit the rock bottom. It is “Us” who need to find the way out of this mess as no one is going to solve our problems especially the current sectarian mess which is a result of narrow mindsets taking weak decisions. To come out of this dire state, we need broad minds with big vision and a desire of moving forward through mutual respect and understanding.

“for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”
New light to illuminate the world
This year’s Nobel Laureates are rewarded for having invented a new energy-efficient and environment-friendly light source – the blue light-emitting diode (LED). In the spirit of Alfred Nobel the Prize rewards an invention of greatest benefit to mankind; using blue LEDs, white light can be created in a new way. With the advent of LED lamps we now have more long-lasting and more efficient alternatives to older light sources.
When Isamu Akasaki, Hiroshi Amano and Shuji Nakamura produced bright blue light beams from their semi-conductors in the early 1990s, they triggered a funda-mental transformation of lighting technology. Red and green diodes had been around for a long time but without blue light, white lamps could not be created. Despite considerable efforts, both in the scientific community and in industry, the blue LED had remained a challenge for three decades.
They succeeded where everyone else had failed. Akasaki worked together with Amano at the University of Nagoya, while Nakamura was employed at Nichia Chemicals, a small company in Tokushima. Their inventions were revolutionary. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps.
White LED lamps emit a bright white light, are long-lasting and energy-efficient. They are constantly improved, getting more efficient with higher luminous flux (measured in lumen) per unit electrical input power (measured in watt). The most recent record is just over 300 lm/W, which can be compared to 16 for regular light bulbs and close to 70 for fluorescent lamps. As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent bulbs and 10,000 hours for fluorescent lights.
The LED lamp holds great promise for increasing the quality of life for over 1.5 billion people around the world who lack access to electricity grids: due to low power requirements it can be powered by cheap local solar power.
The invention of the blue LED is just twenty years old, but it has already contributed to create white light in an entirely new manner to the benefit of us all.
for their discoveries of cells that constitute a positioning system in the brain
How do we know where we are? How can we find the way from one place to another? And how can we store this information in such a way that we can immediately find the way the next time we trace the same path? This year´s Nobel Laureates have discovered a positioning system, an “inner GPS” in the brain that makes it possible to orient ourselves in space, demonstrating a cellular basis for higher cognitive function.
In 1971, John O´Keefe discovered the first component of this positioning system. He found that a type of nerve cell in an area of the brain called the hippocampus that was always activated when a rat was at a certain place in a room. Other nerve cells were activated when the rat was at other places. O´Keefe concluded that these “place cells” formed a map of the room.
More than three decades later, in 2005, May-Britt and Edvard Moser discovered another key component of the brain’s positioning system. They identified another type of nerve cell, which they called “grid cells”, that generate a coordinate system and allow for precise positioning and pathfinding. Their subsequent research showed how place and grid cells make it possible to determine position and to navigate.
The discoveries of John O´Keefe, May-Britt Moser and Edvard Moser have solved a problem that has occupied philosophers and scientists for centuries – how does the brain create a map of the space surrounding us and how can we navigate our way through a complex environment?
How do we experience our environment?
The sense of place and the ability to navigate are fundamental to our existence. The sense of place gives a perception of position in the environment. During navigation, it is interlinked with a sense of distance that is based on motion and knowledge of previous positions.
Questions about place and navigation have engaged philosophers and scientists for a long time. More than 200 years ago, the German philosopher Immanuel Kant argued that some mental abilities exist as a priori knowledge, independent of experience. He considered the concept of space as an inbuilt principle of the mind, one through which the world is and must be perceived. With the advent of behavioural psychology in the mid-20th century, these questions could be addressed experimentally. When Edward Tolman examined rats moving through labyrinths, he found that they could learn how to navigate, and proposed that a “cognitive map” formed in the brain allowed them to find their way. But questions still lingered – how would such a map be represented in the brain?
John O´Keefe and the place in space
John O´Keefe was fascinated by the problem of how the brain controls behaviour and decided, in the late 1960s, to attack this question with neurophysiological methods. When recording signals from individual nerve cells in a part of the brain called the hippocampus, in rats moving freely in a room, O’Keefe discovered that certain nerve cells were activated when the animal assumed a particular place in the environment (Figure 1). He could demonstrate that these “place cells” were not merely registering visual input, but were building up an inner map of the environment. O’Keefe concluded that the hippocampus generates numerous maps, represented by the collective activity of place cells that are activated in different environments. Therefore, the memory of an environment can be stored as a specific combination of place cell activities in the hippocampus.
May-Britt and Edvard Moser find the coordinates
May-Britt and Edvard Moser were mapping the connections to the hippocampus in rats moving in a room when they discovered an astonishing pattern of activity in a nearby part of the brain called the entorhinal cortex. Here, certain cells were activated when the rat passed multiple locations arranged in a hexagonal grid (Figure 2). Each of these cells was activated in a unique spatial pattern and collectively these “grid cells” constitute a coordinate system that allows for spatial navigation. Together with other cells of the entorhinal cortex that recognize the direction of the head and the border of the room, they form circuits with the place cells in the hippocampus. This circuitry constitutes a comprehensive positioning system, an inner GPS, in the brain (Figure 3).
A place for maps in the human brain
Recent investigations with brain imaging techniques, as well as studies of patients undergoing neurosurgery, have provided evidence that place and grid cells exist also in humans. In patients with Alzheimer´s disease, the hippocampus and entorhinal cortex are frequently affected at an early stage, and these individuals often lose their way and cannot recognize the environment. Knowledge about the brain´s positioning system may, therefore, help us understand the mechanism underpinning the devastating spatial memory loss that affects people with this disease.
The discovery of the brain’s positioning system represents a paradigm shift in our understanding of how ensembles of specialized cells work together to execute higher cognitive functions. It has opened new avenues for understanding other cognitive processes, such as memory, thinking and planning.
