'Roughly 12 million adults who visit U.S. doctors' offices and other outpatient settings, or one in 20, are misdiagnosed every year, a new study has found, and half of those errors could lead to serious harm.'
'In a cloning first, scientists create stem cells from adults
Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient's DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men.
The advance, described online in the journal Cell Stem Cell, is the first time researchers have achieved "therapeutic cloning" of adults. Technically called somatic-cell nuclear transfer, therapeutic cloning means producing embryonic cells genetically identical to a donor, usually for the purpose of using those cells to treat disease.
But nuclear transfer is also the first step in reproductive cloning, or producing a genetic duplicate of someone - a technique that has sparked controversy since the 1997 announcement that it was used to create Dolly, the clone of a ewe. In 2005, the United Nations called on countries to ban it, and the United States prohibits the use of federal funds for either reproductive or therapeutic cloning.
The new study was funded by a foundation and the South Korean government.
If confirmed by other labs, it could prove significant because many illnesses that might one day be treated with stem cells, such as heart failure and vision loss, primarily affect adults. Patient-specific stem cells would have to be created from older cells, not infant or fetal ones. That now looks possible, though far from easy: Out of 39 tries, the scientists created stem cells only once for each donor.'

study concludes. "In addition, regular consumption of sugar-sweetened
beverages is associated with elevated cardiovascular mortality."

Now that it is recommended that we 7 to 10 servings of fruits and vegetables per day, I am wondering how many fast food restaurants are going to start offering fried vegetables on the menu? I have eaten many tempura fried vegetables at Japanese restaurants and they are delicious.
