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 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. 54: Nov-Dec 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Plants are not color blind!" Scientists have long known from laboratory experiments that various colors of light can affect stem size, root structure and other aspects of plant growth. But they have remained largely in the dark about the potential practical benefits of the phenomenon. "Using colored mulch to bathe plants in reflected light of certain hues, the South Carolina group (Clemson University) has begun to explore what colors plants prefer in agricultural growing conditions. Last year, for example, the group found that tomatoes grown with red mulch -- made with plastic sheets painted red -- had 20% higher yields than those with black mulch. ... results this year show that potatoes and bell peppers grow best with white mulch...." (Anonymous; "Plants' Colors," Wall Street Journal, September 16, 1987. Cr. J. Covey.) Comment. Many questions arise here, but we'll take only three: (1 ) How do plants sense colors? (2 ) How do different colors mediate growth differently? (3 ) Is all this explicable in terms of evolution? From Science Frontiers #54, NOV-DEC 1987 . 1987-2000 William R. Corliss ...

... Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mysterious Losses And Acquisitions of Color Vision The eyes of most mammals incorporate two types of color-sensitive cones; one for seeing blue light, the other for green light. Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it ... easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on the ...

... . It costs $75 and is published by Springer/Verlag. The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli. As for the stimuli that call forth these exotic sensations; they are usually ...

... Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Bowerbird art for art's sake The bowerbirds of New Guinea and Australia build and decorate marvelously intricate and esthetic works of art. One must classify these impressive structures as works of art, even by human standards. For example, the bowers have geometrical organization and may be oriented to a specific compass direction, depending upon the species. Colorful berries, stones, and, when available, human artifacts are systematically arranged around the bower. Some bowerbirds even take a piece of bark in their bills and paint their bowers with colored berry juices. Each species has a certain style, but the bowers vary from individual to individual and with the age of the bird. Manifestly, these birds use tools for artistic purposes. Or do they ... mates, but the males often chase females away, although mating does eventually occur within the bowers. A second explanation is that the bowers symbolize territorial rights. In this context, bowerbirds fre-quently raid and destroy neighboring bowers, stealing choice decorations -- all very human-like behavior. (Diamond, Jared M.; "Evolution of Bowerbirds' Bowers: Animal Origins of the Esthetic Sense," Nature, 297:99, 1982.) Comment. Is human art any more profound than that of the bowerbirds? Human artists doubtless feel they are doing something more than attracting mates or proclaiming territory. Unfortunately, we cannot ask the bowerbirds what they are thinking as they carefully select colors and develop designs. From Science Frontiers #22, JUL-AUG 1982 . 1982- ...

... reviews a new book with the above title. The authors are Marcia and Robert Ascher, who have studied roughly 200 Inca quipus, demonstrating in the process that the Incas did indeed have a "written" language as well as a surprisingly sophisticated system of mathematical notation. A quipu appears to the uninitiated as a meaningless jumble of strings. To an Inca quipu reader, though, the positioning and colors of the secondary and tertiary strings appended to the primary cord all have meaning. The knots along each string also convey messages. Quipus incorporated, in a sense, three-dimensional notation, as opposed to the two-dimensional text on this page. Inca mathematical developments are inherent in quipu notation, which clearly reveals base-of10 positional notation and the use of the zero. Instead of ... tangle of colored strings, the quipus actually display sophisticated concepts of number, geometrical configuration, and logic. (Urton, Gary; "Inca Encodements," Science, 216:869, 1982.) Reference. For more on quipus and the Inca civilization, see our Handbook: Ancient Man. Ordering information here .
