1. SHUTTLE: THE SPACE SHUTTLE DOESN'T WORK IT NEVER DID WORK.

Why is everyone afraid to say so? The real problem isn't foam falling off the fuel tank. The shuttle was sold to Congress as a way to launch things into space more cheaply. On the contrary, it's the most expensive way to reach space ever conceived. The problems we're facing now result from the refusal to acknowledge that reality. Initially, anything that went into space, including commercial and military satellites, was required to be launched from the shuttle. With the total cost of the shuttle program at about $150B, the average cost/flight is about $1.3B. The shuttle was strangling space development before the Challenger disaster. Then it was declared to be a science laboratory, but no field of science has been affected in any way by research that has been conducted on the shuttle or space station. The last scheduled research mission was the final flight of Columbia in 2003. The shuttle's only mission now is to supply the ISS.

2. ECHINACEA: THE THEME THIS WEEK IS "THINGS THAT DON'T WORK."

There is no reason why herbal remedies couldn't work. The bark and leaves of the angiosperms are packed with biologically active chemicals. Surely, among the thousands of herbals on the market, one must work. With a budget of over $100M, and under pressure to show it's not biased against alternative medicine, the new National Center of Complementary and Alternative Medicine at NIH set out to find it. Well, ephedra worked, but side effects were fatal (WN 2 Jan 04). Why not ask herbalists what would be a sure thing? Answer: "Echinacea." Millions of Americans use the purple cone flower to prevent or treat colds. Native Americans used it, and we all know that primitive societies had wondrous cures that today's narrow-minded scientists can't explain. But in initial tests, it didn't seem to work (WN 28 May 04). This week, the New England Journal of Medicine published a convincing NCCAM funded test: Echinacea does not prevent or cure colds.

3. PRAYER: FOLLOW-UP STUDY FINDS NO BENEFIT FOR HEART PATIENTS.

Prayers for the sick are probably the most widely practiced healing tradition in the world. An earlier study with the same lead author, Mitchell Krucoff, MD, at Duke University Medical Center, continues to be widely cited as scientific evidence for the power of prayer. In a much larger follow-up study, however, 748 patients who had common cardiac procedures were not helped by intercessory prayers of groups throughout the world, drawn from Christian, Muslim, Jewish or Buddhist denominations. You will not be surprised that the authors conclude that so-called "noetic" therapies, defined as therapies that don't involve the use of tangible drugs or devices, deserve further scientific scrutiny. Science assumes that all events result from natural causes (WN 3 Dec 04).
