...world community, we have held landmark conferences in Stockholm (1972) and Rio de Janeiro (1992), negotiated dozens of multilateral agreements, built up institutions like the U.N. Environment Program and set out a common vision of progress in the Millennium Development Goals, which include eradicating poverty and hunger, reducing child mortality and achieving gender equality and universal primary education.

While the new information about PYY won't help you choose between a high-protein or low-fat diet, it goes a long way toward explaining...
What gets neuroscientists excited is that most of these digestive hormones seem to affect the same group of neurons in the hypothalamus, a subsection of the brain that acts as a kind of master regulator of some of our more basic instincts--hunger, thirst, sleep, sex. That means if PYY fails to be a good candidate for a new antiobesity drug, researchers may find another target in the brain that works better. Alternatively, studying PYY may help with the opposite problem--loss of appetite--which so often affects cancer patients and people with AIDS...
