...march 26, President Obama announced that the U.S. and Russia will cut their deployed long-range nuclear arsenals by 30% over seven years. The START Follow-On Treaty, as it is known, is the descendant of a series of Cold War arms-control agreements that had an unlikely progenitor: the spectacular failure of the most ambitious disarmament program ever conceived. The Versailles Treaty of 1919, which was designed to disarm Germany but which failed to prevent World War II, led to a more sober approach to arms control predicated on the belief that conflict is inevitable and a balance...
...Half of this grant has been provided by the Chinese government, whose high-level interest in the project is easy to understand. Panthera tigris amoyensis is the progenitor of all modern tigers and the only subspecies unique to China. "You have a culture that reveres the tiger," says Tilson. "It's part of their fabric." 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...
...studies the molecular controls over the development of different kinds of neurons—cells that comprise the nervous system, which includes the brain and spinal cord—and figures out how to stimulate the growth of these neurons in the brain with already-present progenitor (“stem”) cells. In specifically examining motor neurons that connect the brain to the spinal cord, Macklis aims to grow new neurons in damaged or malfunctioning parts of the brain and reactivating the controls and skills those parts once had. But despite their own expertise, Macklis...

Scholars from southern India claim it ought to be linked to proto-Dravidian, the progenitor of languages like Tamil, while others think it is related to the Vedic Sanskrit of early Hinduism, the ancestor of Hindi and other languages spoken in India's north. And while cultural agendas within India have stymied collaborative efforts, the enmity between India and Pakistan has impeded archaeological breakthroughs. Ganeriwala, a desert site in Pakistan that possibly holds the ruins...
...masse the way flocks of birds do, eliminating the immediate tip-off that a serious pathogen is at large. None of that is Mexico's fault either. In fact, since human tourists and domesticated animals cross into Mexico all the time, there's every reason to believe that the progenitor virus behind the epidemic hitched a ride in one of them...
