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. 75: May-Jun 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The first food: tholin "You've just had a hard day evolving into the first life-form on your primitive planet, and you're ready to chow down. Problem: What can you eat? A quick survey of the food chain isn't promising; you're it. Do you simply starve to death, ending your world's brief experiment with life? Not if a rust-colored substance called tholin is within reach. Tholin may have served as breakfast, lunch, and dinner for the first life on Earth." The tholins are hard, red-brownish substances made of complex organic compounds. They do not exist naturally on earth, because our present oxidizing atmosphere blocks their synthesis. However, tholins can be made in the lab by subjecting mixtures of methane, ammonia, and water vapor to simulated lightning discharges. Conditions like this probably exist many places in the universe. In fact, the icy moons of the outer solarsystem planets appear ideal places for tholin manufacturing. What would eat such stuff? Lab tests show that many kinds of bacteria love it and thrive on it. (Chaikin, Andrew; "First Foods," Discover, p. 18, February 1991.) Comment. A purposeless universe that just happens to create a substance for primitive life? Strange that things should be this way!

... Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Prebiological chemistry in titan's atmosphere From the abstract of the referenced paper: "An organic heteropolymer (Titan tholin) was produced by continuous dc discharge through a 0.9 N2 / 0.1 CH4 gas mixture at 0.2 mbar pressure, roughly simulating the cloudtop atmosphere of Titan [one of Saturn's moons]. Treatment of this tholin with 6N HCl yielded 16 amino acids by gas chromatography after derivatization to N-trifluroacetyl isopropyl esters on two different capillary columns...The presence of 'nonbiological' amino acids, the absence of serine, and the fact that the amino acids are racemic within experimental error together indicate that these molecules are not due to microbiol or other contamination, but are derived from the tholin...These results suggest that episodes of liquid water in the past or future of Titan might lead to major further steps in the probiological organic chemistry on that body." (Khare, Bishun N., et al; "Amino Acids Derived from Titan Tholins," Icarus, 68:176, 1986.) From Science Frontiers #49, JAN-FEB 1987 . 1987-2000 William R. Corliss ...

... Interstellar absorption Bands). These dark absorption bands in stellar spectra have never been correlated with known chemical compounds. Now, L. Allamandola and F. Salama (NASA-Ames) find that the DIBs may be due to polycyclic aromatic hydrocarbons! A more digestible descriptor would be "soot," like that found in automobile exhaust and on your barbecued steak. (Weiss, Peter; "Cosmic Soot Fills Space between the Stars," New Scientist, p. 15, March 13, 1993.) Organic asteroids. Some asteroids are abnormally red. Newly discovered asteroid 5145 Pholus is 3 times brighter at near-infrared wavelengths than it is in the visible portion of the spectrum. The best explanation so far for this redness is that 5145 Pholus is veneered with organic compounds called "tholins." Tholins are synthesized when methane and other simple chemicals are bathed in ultraviolet and particulate radiations. Tholins have even been dubbed the "first foods" of aspiring new life forms!
