Because characteristics like limb development are governed by powerful families of genes known as Hox genes, the fishapod's curious mix of features intrigues developmental biologists as much as it does paleontologists. Recent experiments on mice by University of Geneva geneticist Denis Duboule and his colleagues, for example, show that Hox genes control limb development in two stages. "Even though the same genes are involved," says Duboule, "separate processes govern the development of arms and legs and the development of hands and feet...
...barrier. Our immigration policy must be inviting, but it is vital for our nation’s security that we control who enters the U.S.Finally, and most importantly, an immigration policy that does not recognize the root of the problem is merely applying a bandage to a severed limb. Lost in much of the recent discussion is the fact that the U.S.-Mexico border is home to the largest disparity of wealth in the world. The per capita GDP of Mexico is one quarter that of the U.S., and an estimated 40 percent of the population lives below the poverty...
...make alliances as hard as they are important. That is not to say we should never act unilaterally. Sometimes the right thing to do will spawn backlash, and we should do it anyway. But that makes it all the more imperative that when we do go out on a limb, we get things right. In those instances, we need to make our margin of error as small as humanly possible. Too many in the Bush Administration, alas, did the opposite. They sent far too few troops, were reckless in postinvasion planning and turned a deaf ear to constructive criticism, even...
...Iraq. Few female troops are out of the line of fire. While military police patrol Baghdad with Iraqi cops who skirmish almost daily with insurgents, women clerks and cooks inside U.S. camps are vulnerable to rocket and mortar attacks by militants. Such hazards underscore the threats to life and limb that still confront all U.S. troops in Iraq, even as the military attempts to turn over more combat responsibility to Iraqi forces. First Sergeant Michelle Collins, 38, who waits anxiously every day for "her kids" to come back to Camp Liberty from patrol, says, "An IED [improvised explosive device...
When TIME printed Braddock's picture last year, letters poured in from readers asking what had become of the young man photographed on a doctor's examining table calmly inspecting the remains of his severed limb. It's a scene being played out daily as soldiers and Guardsmen come home from Iraq seeking treatment at Walter Reed Army Medical Center in Washington, Brooke in San Antonio and veterans' hospitals nationwide. Three years since the start of the war, the toll of seriously wounded from Iraq exceeds 7,600--men and women without limbs, with horrid burns, with brain damage...
