About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions

Subscriptions to the Science Frontiers newsletter are no longer available.

Compilations of back issues can be found in Science Frontiers: The Book, and original and more detailed reports in the The Sourcebook Project series of books.

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gravity And Going Around In Ellipses We thought that our readers might like to know that the force of gravity apparently has no significant effect on circumnutation. Now circumnutation is the result of an "impressively ubiquitous mechanism" in all elongating plant organs. More simply, it is the elliptical weaving motion seen in the tips of growing leaves, shoots, flower stalks, branch roots, etc. In a 4- to 5-day-old sunflower seedling, the ellipse traced is 6-8 millimeters long and takes about 110 minutes. The ellipses result from differ-ential growth in the elongating plants. No one knew whether the force of gravity played a role in circumnutation until some sunflower seedlings were flown on Spacelab 1. Zero-g did not affect circumnutation at all. (Brown, Allan H. and Chapman, David K.; "Circumnutation Observed without Significant Gravitational Force in Spaceflight," Science, 225:230, 1984.) Comment. Nature seldom indulges in frivolous actions, but we just may have a phenomenon here that has absolutely no deeper significance. From Science Frontiers #35, SEP-OCT 1984 . 1984-2000 William R. Corliss ...
