Does Intercessory Prayer For Sick People Actually Help Heal Them?
Health and religion have always been intertwined, most obviously through prayer on behalf of the sick. Does intercessory prayer for sick people actually help heal them? For thousands of years some people have believed so. But new Brandeis University research in the Journal of Religion this month shows that over the last four decades, medical studies of intercessory prayer - the prayer of strangers at a distance - actually say more about the scientists conducting the studies than about the power of prayer to heal.

Bacteria Are First Sensed By Cells Lining Blood Vessels, Not Immune Cells
Paul Kubes and colleagues, at the University of Calgary, Canada, have provided evidence in mice to refute the paradigm that the initial phase of the immune response to infection with Gram-negative bacteria (the recruitment of immune cells known as neutrophils to the site of infection) is triggered following immune sentinel-cell recognition of the bacterial molecule LPS via the protein TLR4. Rather, the researchers found that LPS recognition by TLR4 on the cells that line blood vessels (endothelial cells) is the crucial event that initiates neutrophil recruitment and bacterial clearance in mice.

Health Care 101: Key Challenges In The Debate

Several news organizations had explainers detailing the ongoing the health reform debate. The New York Times created an online primer, highlighting key proposals currently under discussion: the individual/employer mandates, and a public insurance plan and marketplace. The Times includes pros/cons as well as explanations of the possible ways to pay for an overhaul and the process by which the three current health care plans will merge into one final piece of legislation (Hossain, 6/18). The Associated Press has a Q&A on why high health costs are harmful to the economy. Health care "accounts for about one-sixth of the entire economy," totaling "about $2.5 trillion." The AP explores how "rising health care costs affect workers and businesses," "the impact of 50 million Americans having no insurance," and whether "the health care system must be fixed first to repair the economy" (Johnson, 6/18).
