- Zero-gravity protein is no reason to build a space station,
- say scientists
-
-
- One of the arguments for building the multibillion-dollar
- space station Freedom is that it would provide a zero-gravity
- laboratory to grow bigger and purer protein and silicon
- crystals. But increasingly there is a question as to whether the
- crystal-growing techniques, at least for proteins, are all that
- reliable. Reviewing a decade's worth of such space efforts,
- scientists writing in Nature found that less than a quarter of
- the experiments actually worked, and then with only mixed
- success. Their recommendation: rent time aboard the already
- orbiting Russian space station Mir.
