Anti-Abortion Groups Threaten Overhaul Because Of Funding Questions
"Abortion is not explicitly mentioned in any of the major health-care bills under consideration in Congress," The Washington Post reports, but "abortion opponents charge that the legislation would make abortion more widely available and more common by requiring insurance plans to pay for the procedures and providing government funding to subsidize plans that pay for them."

MU Scientists Convert Pigs' Connective Tissue Cells Into Stem Cells
For years, proponents have touted the benefits of embryonic stem cell research, but the potential therapies still face hurdles. Side effects such as tumor development, a lack of an effective and long-term animal model to test new therapies, and genetic incompatibility between the host and donor cells are some of the problems faced by researchers. Now, scientists at the University of Missouri have developed the ability to take regular cells from a pig"s connective tissues, known as fibroblasts, and transform them into stem cells, eliminating several of these hurdles. The new study appeared in a recent issue of the Proceedings of the National Academy of Sciences (PNAS).

Insured Immigrants Have Lower Medical Expenses Than Insured US-born Citizens

A nationally representative study found that immigrants spent less on medical expenses than their US-born counterparts, even after controlling for level of health insurance coverage and other confounding factors. Researchers used data for non-elderly adults ages 19-64 from the 2003 Medical Expenditure Panel Survey. They found that approximately 44 percent of recent immigrants and 63 percent of established immigrants were fully insured. Yet recent immigrants were responsible for only about 1 percent of public medical expenditures even though they constituted 5 percent of the population. "These findings suggest, contrary to stereotypes, that insurance premiums paid for immigrants may actually be cross-subsidizing the medical expenses of those who are US born," the study"s authors claimed.
