Genetically modified foods
Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides.
In the future, genetic modification could be aimed at altering the nutrient content of food, reducing its allergenic potential, or improving the efficiency of food production systems. All GM foods should be assessed before being allowed on the market. FAO/WHO Codex guidelines exist for risk analysis of GM food.

I started to run because I felt desperately unfit. But the biggest pay-off for me was – and still is – the deep relaxation that I achieve by taking exercise. It tires me out but I find that it does calm me down. When I started running seven years ago, I could manage only 400 meters before I had to stop. Breathless and aching, I walked the next quarter of a mile, alternating these two activities for a couple of kilometers.
When I started to jog I never dreamt of running in a marathon, but a few years later I realized that if I trained for it, the London Marathon, one of the biggest British sporting events, would be within my reach. My story shows that an unfit 39-year-old, as I was when I started running, who had taken no serious exercise for twenty years, can do the marathon – and that this is a sport in which women can beat men. But is it crazy to do it? Does it make sense to run in the expectation of becoming healthier?
My advice is: if you are under forty, healthy and feel well, you can begin as I did by jogging gently until you are out of breath, then walking, and alternating the two for about three kilometers. Build up the jogging in stages until you can do the whole distance comfortably.

Today, Cohen, 49, is the Brooklyn-based founder of BetterThanFiction Productions, a documentary film company; Khan is the director of the University of Cape Town Opera School. “I Live to Sing," a feature-length documentary directed and produced by Cohen, focuses on three of Khan's black students who made their way from humble beginnings in often poverty-ridden townships to excel in opera ‒an art form most closely associated with white, elite audiences and performers.

Gabriel García Márquez was a Literary Giant
With a Passion for Journalism
By Karla Zabludovsky Friday, April 18,2014
The late Gabriel García Márquez holds a special place in the hearts of journalists.
Like Charles Dickens, Mark Twain and Ernest Hemingway — or contemporaries like Pete Hamill and Tom Wolfe — García Márquez, a titan of 20th century literature, honed his writing skills as a reporter
before he became a celebrated novelist.
Even as his literary star rose, García Márquez, known colloquially across Latin America as Gabo, spoke proudly, tenderly and frequently about journalism.
“Those who are self-taught are avid and quick, and during those bygone times, we were that to a great extent in order to keep paving the way for the best profession in the world… as we ourselves called
it," said García Márquez during a speech about journalism at the 52nd Assembly of the Inter American Press Association in 1996.
