Among Nature’s most intriguing phenomena are the partnerships formed by any different species. The name used for these relationships, Symbiosis, comes from Greek meaning "living together". Not all symbiotic relationships are the same. There are some called commensal relationships, in which one partner gains a benefit while the other gains little or none but is not harmed. One example is the relationship between two types of fish remoras and sharks. The remora, which is long and often striped, attaches itself to a shark (sometimes to another type of fish or a whale), using a sucker on its head. When the shark makes a kill, the hitchhiker briefly detaches itself to feed on the scraps. Another type of symbiotic relationship is parasitism, in which one partner benefits at the expense of others. Ticks and tapeworms are among familiar parasites. 

The third type of symbiotic relationship, called mutualism, is a true partnership in which both partners benefit. The relationship may be limited as when zebras and wild best graze together on the vast African grasslands. Each species can survive on its own, but together their chances of detecting predators are improved because each contributes a specially keen sense.

As the Sun inches closer to its peak activity in its solar cycle, an explosion has been picked up behind the north-eastern limb of the star in our solar system. Solar observatories saw bits and pieces of the explosion, which remain obscured in view from Earth's orbit. The explosion was spotted on 31 July at around 2309 UT and Earth-orbiting satellites registered a long-lasting C9.3-class solar flare. "The intensity is probably an underestimate because it was partially eclipsed by the edge of the sun. Nasa's Solar Dynamics Observatory (SDO) saw hot debris flying away from the blast site," space weather, which tracks the solar activity, reported.

While the explosion was powerful, experts have predicted that Earth is not in the line of fire from the Sun. Scientists are expected to get a view of the active region later this week as it comes to sight. Earth is not in the line of fire. The explosion is significant because it may herald an active region set to emerge over the sun's north-eastern limb later this week. A new sunspot group could bring an end to weeks of relative quiet," space weather said in its report

It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us."
Is that going to be a great day, or what?
All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German.
 As complex as all this sounds, it could turn out to be relatively simple.

What is genomics?

IN GORILLA society, power belongs to silverback males. These splendid creatures have numerous status markers besides their back hair: they are bigger than the rest of their band, strike space-filling postures, produce deeper sounds, thump their chests lustily and, in general, exude an air of physical fitness. Things are not that different in the corporate world. The typical chief executive is more than six feet tall, has a deep voice, a good posture, a touch of grey in his thick, lustrous hair and, for his age, a fit body. Bosses spread themselves out behind their large desks. They stand tall when talking to subordinates. Their conversation is laden with prestige pauses and declarative statements. The big difference between gorillas and humans is, of course, that human society changes rapidly. The past few decades have seen a striking change in the distribution of power—between men and women, the West and the emerging world and geeks and non-geeks.

Women run some of America’s largest firms, such as General Motors (Mary Barra) and IBM (Virginia Rometty). More than half of the world’s biggest 2,500 public companies have their headquarters outside the West. Geeks barely out of short trousers run some of the world’s most dynamic businesses. Peter The, one of Silicon Valley’s leading investors, has introduced a blanket rule: never invest in a CEO who wears a suit. Yet it is remarkable, in this supposed age of diversity, how many bosses still conform to the stereotype. First, they are tall: in research for his 2005 book, “Blink”, Malcolm Gladwell found that 30% of CEOs of Fortune 500 companies are 6 feet 2 inches or taller, compared with 3.9% of the American population. People who “sound right” also have a marked advantage in the race for the top. Quantified Communications, a Texas-based company, asked people to evaluate speeches delivered by 120 executives. They found that voice quality accounted for 23% of listeners’ evaluations and the content of the speech only accounted for 11%.
 Academics from the business schools of the University of California, San Diego and Duke University listened to 792 male CEOs giving presentations to investors and found that those with the deepest voices earned $187,000 a year more than the average.
 Physical fitness seems to matter too: a study published this month, by Peter Limbach of the Karlsruhe Institute of Technology and Florian Sonnenburg of the University of Cologne, found that companies in America’s S&P 1500 index whose CEOs had finished a marathon were worth 5% more on average than those whose bosses had not.

Her name was Sulekha, but since her childhood everyone had been calling her Bholi, the simpleton. She was the fourth daughter of Ramlal. When she was ten months old, she had fallen off the cot on her head and perhaps it had damaged some part of her brain. That was why she remained a backward child and came to be known as Bholi, the simpleton. At birth, the child was very fair and pretty. But when she was two years old, she had an attack of smallpox. Only the eyes were saved, but the entire body was permanently disfigured by deep black pockmarks. Little Sulekha could not speak till she was five as she was a slow learner, and when at last she learnt to speak, she stammered. The other children often made fun of her and mimicked her. As a result, she talked very little. Ramlal had seven children — three sons and four daughters, and the youngest of them was Bholi. It was a prosperous farmer’s household and there was plenty to eat and drink. All the children except Bholi were healthy and strong. The sons had been sent to the city to study in schools and later in colleges. Of the daughters, Radha, the eldest, had already been married. The second daughter Mangla’s marriage had also been settled, and when that was done, Ramlal would think of the third, Champa. They were good-looking, healthy girls, and it was not difficult to find bridegrooms for them. But Ramlal was worried about Bholi. She had neither good looks nor intelligence. From her very childhood Bholi was neglected at home. She was seven years old when Mangla was married. The same year a primary school for girls was opened in their village. The Tehsildar sahib came to perform its opening ceremony. He said to Ramlal, “As a revenue official you are the representative of the government in the village and so you must set an example to the villagers. You must send your daughters to school.” That night when Ramlal consulted his wife, she cried, “Are you crazy? If girls go to school, who will marry them?” But Ramlal had not the courage to disobey the Tehsildar. At last his wife said, “I will tell you what to do. Send Bholi to school. As it is, there is little chance of her getting married, with her ugly face and lack of sense. Let the teachers at school worry about her.”

How was Ramlal expected to set an example for the villagers?

Indeed the western recession is really the beginning of good news for India! But to understand that we will have to move away for a while from the topic of western recession . . . . . . . to the Japanese recession! For years the Japanese style of management has been admired. However, over the last decade or so, one key question has sprung up ‘if Japanese management style is as wonderful as described then why has Japan been in a recession for more than a decade?'
The answer to this question is very simple. Culture plays a very important part in shaping up economies. What succeeds in one culture fails in another. Japanese are basically nonmaterialistic. And however rich they become, unlike others, they cannot just keep throwing and buying endlessly. And once they have everything they need; there is a saturation point. It was only when companies like Toyota realized that they cannot keep selling cars endlessly to their home market that they went really aggressive in the western markets-and the rest is history. Japanese companies grew bigger by catering to the world markets when their home markets shrunk.

served equally well. They were lured through advertising and marketing techniques of ‘dustbinisation' of the customer; and then finally, once they became ready customers, they were given loans and credits to help them buy more and more. When all the creditworthy people were given loans to a logical limit, they ceased to be a part of the market. Even this would have been understandable if it could work as an eye-opener. Instead of taking the 'Right Step' as Toyota did, they preferred to take a 'shortcut'. Now banks went to the noncredit worthy people and gave them loans. The people expectedly defaulted and the entire system collapsed.

Now like Toyota western companies will learn to find new markets. They will now lean towards India because of its common man! The billion-plus population in the next 25 years will become, a consuming middle-class. Finally, there will be a real surge in income of these people and in the next fifty odd years, one can really hope to see an equal world in terms of material plenty, with poverty being almost nonexistent! And this will happen not by selling more cars to Americans and Europeans. It will happen by creating markets in India, China, Latin America and Africa, by giving their people purchasing power and by making products for them.
The recession has made us realize that it is not because of worse management techniques, but because of limits to growth. And they will realize that it is great for planet earth. After all, how many cars and houses must the rich own before calling it enough? It's time for them to look at others as well. Many years back, to increase his own profits, Henry Ford had started paying his workers more, so that they could buy his cars. In similar fashion, now the developed world will pay the developing world people so that they can buy their cars and washing machines.
The recession will kick - start the process of making the entire world more prosperous, and lay the foundation of limits to growth in the west and the foundation of real globalization in the world - of the globalization of prosperity. And one of its first beneficiaries will be India.
