...fact, at least 15 major studies have shown higher death rates for adults after yo-yo weight cycling. "Research consistently links repeat dieting to increased weights instead of lower ones," says Frances Berg, a nutritionist and author of the book Underage and Overweight. Meanwhile, Berg adds, "Children can suffer nutrient deficiencies, immune suppression and dangerous stress levels...
Here's how the process works: scientists biopsy stem or satellite muscle cells from a livestock animal, such as a chicken, cow or pig. The cells are then placed in a nutrient-rich medium where they divide and multiply, and are then attached to a scaffolding structure and put in a bioreactor to grow. In order to achieve the texture of natural muscle, the cells must be physically stretched and flexed, or exercised, regularly. After several weeks, voila, you have a thin layer of muscle tissue that can be harvested and processed into ground beef, chicken or pork, depending...
...Cloning enables the livestock industry to do in a fraction of the time what breeders have been doing throughout history, narrowing the gene pool to its most desirable genes. Beyond that, say cloners, future benefits include production of genetically engineered animals that could offer a variety of benefits - more nutrient-rich milk, for example, for people without adequate access to food...
...sound far-fetched, but Yunus offers up a real-world example: a partnership between the French foods giant Danone and Yunus' Grameen Group to sell nutrient-enriched yogurt to poor children in Bangladesh. He calls it the "world's very first consciously designed multinational social business"?a company that doesn't insist on an ongoing return to shareholders. Whether there's enough motivation in boardrooms to make the idea grow is a big question, but there are some 100 million microborrowers around the world. So it's a nice client base...
...residents downstream, China's efforts to manage the Mekong also threaten their way of life. An astounding 17% of all fish caught in inland waters worldwide come from this generous river, while 90% of the basin's residents are subsistence farmers who largely depend on the Mekong's nutrient-rich waters to feed their fields. Yet Chinese dams, along with engineering projects to make the river navigable by larger vessels, have begun to ravage the river's ecology by blocking sediment and producing unnatural water flows that dissuade fish migration and spawning. The nonprofit Southeast Asian Rivers Network estimates that...
