...left untreated can lead to death. Immunotherapy is designed to build up the body's tolerance to such "toxins" by gradually increasing patients' exposure to them over several weeks or months, says Hugh Sampson, who runs the Jaffe Food Allergy Institute at Mount Sinai. "We start at the microgram level, scale up to milligrams and may end with grams [of peanuts]," says Sampson, but he warns people not to try the program at home. "Every patient has an adverse reaction when we increase the dose," and in severe cases, the patient may need immediate medical attention. (See how to prevent...

Different economies can bear different levels of government debt, depending on their ability - real or perceived - to finance it. While Greece's small and uncompetitive economy is struggling to stay afloat, Japan, with ample domestic sources...

By pulling a Chinese subspecies from the brink of extinction, China seeks not only to overturn an appalling record on conservation and the environment but also to gain a powerful new icon of national resurgence - not a cuddly giant panda this time but a formidable...
...Libya's conservatives, who resist calls for democratic change. "They are idiots," he says, waving his hand as though to dismiss them. When asked what kinds of new political freedoms he wants for Libya - such as freedom of speech, or privately owned media - Saif replied without hesitating: "Everything - a level of freedom like in Holland." That would be a stunning departure from his father's 40-year rule, in which the country has carved a far different path from the West...
