...group of senators may quietly succeed, if only incrementally, where President Clinton's frontal assault on the health-care system failed. The Senate Labor and Human Resources Committee today passed health insurances changes that would make it easier for millions of Americans to keep health insurance coverage when they switch jobs or get sick -- one of Clinton's central reform goals. Under the Health Insurance Reform Act, which should reach the Senate floor this fall, no one who continues to pay insurance premiums can be excluded for health reasons or saddled with a new waiting period simply because...
...Senate approved a similar measure. Although support for the resolution was high,TIME World Editor James Collinssays the vote was chiefly an expression of dissatisfaction with President Clinton's Bosnia policy, and may not be veto-proof. "If it comes right down to it, a lot of Democrats will switch rather than embarrass their president." Under the plan, the embargo would be lifted after withdrawal of U.N. troops now on the ground or within 12 weeks of a request by the Bosnian government...
...latest major drug to be considered for the switch is Zantac, an anti-ulcer medication manufactured by Glaxo. Just two weeks ago, two advisory panels to the FDA gave preliminary approval for it to be sold over the counter as a heartburn remedy. Final approval from the fda, which normally concurs with its advisers' recommendations, could set the stage for a marketing war next year among three pharmaceutical giants for dominance of the $1 billion market for heartburn drugs...
Only during the past decade have scientists begun to tease apart the mysteries of Hox genes. Clustered in groups of eight to 11, on as many as four chromosomes in a developing embryo's cells, these genes switch on and off in sequence. Since embryos mature from the top down, explains biologist Cliff Tabin of the Harvard Medical School, a Hox gene that turns off a bit early, or stays on just a touch longer, can make a dramatic difference in the formation of the embryo. Swans, for example, have more neck vertebrae than chickens and thus longer necks. That...
...fanlike progression that runs from the smallest digit to the largest. In Geneva, Duboule and his colleagues tracked the activity of four Hox genes in the budding feet of embryonic mice and found precisely this pattern. By contrast, studies showed that in the zebrafish, the Hox genes switch off earlier, perhaps to ensure that a flexible fin ray (useful for swimming) will form in the place of feet. Duboule speculates that if these genes could be tricked into staying on just a bit longer, the fins of the zebrafish might sprout appendages suggestive of primitive feet...
