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. 22: Jul-Aug 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Nomads Within Us It was originally believed that human chromosomes were fixed at conception and all subsequent organic development proceeded from the instructions encoded on them. Biologists have recently discovered that genes grasshopper about, constantly modifying genetic instructions -- at least that's the current thinking. Additional modification of genetic instructions seems to be accomplished by entities called "nomads" or "mobile dispersed genetic elements." One type of nomad is a simple ring of DNA called a plasmid. Plasmids seem to be identical to a kind of virus called a retrovirus, which can penetrate into cells and tamper with gene expression; that is, the way genetic instructions are interpreted. Plasmids have been discovered in maize, fruit flies, bacteria, and, now, humans -- and healthy people at that. No one is quite sure what these plasmids do. Even though they look like retroviruses, they may not be associated with illness, but rather help organisms adapt to changing environments. But no one really knows. (Anonymous; "Human Wandering Genes Can Live on Their Own," New Scientist, 94:18, 1982.) Comment. So, the human body is not only beset by new genetic instructions and the static introduced by invading viruses and other disease agents, but it has an indigenous population of nomads continually fiddling with our cells' genetic instructions. Our bodies seem more like Grand Central Station with trains loaded with new biological ...

... Science Frontiers ONLINE No. 128: MAR-APR 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Viruses as Ancient Artifacts HTLV-1 is a blood-borne retrovirus that causes leukemia in about 3% of those carrying it. In southern Japan, roughly 4% of the populace are afflicted with this virus, so are some isolated groups living today in Columbia and Chile. Does this correlation prove that South America received settlers from Japan in the distant past? Such a biological linkage would augment pottery evidence from Peru and, especially, Ecuador where Jomon-style pottery 4,000-5 ,000 years old has been found on the coast. However, the HTLV-1 virus also could have been introduced to South America by more recent visitors. Is there any way to fix the timing of HTLV-1 's introduction to South America? Actually, there is. The DNA in viruses is not as durable as pottery shards, but it does hang around for a while, as seen is recent efforts to ex-tract DNA from from frozen mammoths for possible "revival" of the species. A team of Japanese and Chilean scientists has been searching for DNA surviving in 104 mummies deposited in South America's arid Atacama Desert 1,200-1 ,500 years ago. Two of the mummies still retained DNA; and one of them included shards of DNA from HTLV-1 . This certainly doesn't prove trans-Pacific diffusion, but it helps. (Holden, Constance; "Backtracking ...
