... Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Forest Rings No! These rings have nothing to do with crop circles, nor with fairy rings either. Forest rings are best appreciated from a light plane. Hunters and hikers in Canada's boreal forests walk right across the rings without noticing them. But from the air, they are striking apparitions. Most are less than 300 meters in diameter, but the largest is 2 kilometers across. Basically, they are annuli of sparse growth amid dense stands of trees both inside and outside the rings. The barren rings -- some 2,000 have been found -- appear light-colored against the dark green of the healthy forest growth. Why don't trees grow well within the rings, and why the neat circles? At first expanding rings of fungus infection were suspected, something perhaps like the fungus that creates those fairy rings on lawns. But no fungus has been found on the tree roots. One curious fact was discovered about the soil where tree growth is sparse. The soil constituting the rings is poorly drained and is depressed 1-2 meters below the surrounding healthy forest. These circular depressions support mainly peat and tamaracks. But what causes these ring-shaped depressions? One theory holds that the rings are the suface expressions of diamond-bearing kimberlite pipes, like those in South Africa. A few prospectors are already staking diamond-mine claims! Another theory supposes that the rings are created by huge ...

... the heart of the LDG problem: Where did this immense amount of widely dispersed glass shards come from? Was it really created during the searing, sand-melting impact of a cosmic projectile? This is how today's catastrophists would have it? At least three "minor" problems bedevil the accepted impact theory. The surface of the Great Sand Sea shows no sign of a giant crater. Neither do microwave probes deep into the sand by satellite radar. LDG seems too pure to be derived from a messy cosmic collision. Known impact craters, such as that at Wabar in Saudi Arabia, are littered with bits of iron and other meteorite debris. Not so at the LDG sites. LDG is concentrated in two areas. One is oval-shaped; the other is a circular ring 6 kilometers wide and 21 kilometers in diameter. The ring's wide center is devoid of LDG. Could there have been a "soft" projectile impact; that is the detonation of a meteorite, perhaps 30 meters in diameter, 10 kilometers or so above the Great Sand Sea? The searing blast of hot air might have melted the sand beneath. Such a craterless impact is thought to have occurred in the 1908 Tunguska Event in Siberia. Another theory has a meteorite glancing off the desert surface leaving a glassy crust and a shallow crater that was soon filled in. But there are two known areas of LDG. Were there two cosmic projectiles in tandem? As of 1999, the origin of the beautiful green LDG remains an enigma. And of course deserts are dynamic places. ...

Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Hand-reading More Useful Than Palm-reading After learning that mutations in a single gene in mice affected not only the development of their digits but also their ovaries and testes, J. Manning and his colleagues decided to see if there is a link between human hand shape and fertility. There is! Men with hands that are not precise mirror images of each other tend to produce fewer sperm. Manning asserts, "The more asymmetry, the fewer sperm." Easier to test yourself are the relative lengths of your ring and index fingers. Men tend to have ring fingers that are longer than their index fingers. The greater this difference in males, the higher their levels of testosterone, a hormone associated with fertility. In women, the same fingers are usually about equal in length. However, in contrast to males, larger index fingers are correlated with the increased presence of fertility hormones, such as estrogen and lutenizing hormones.

... Science Frontiers ONLINE No. 124: Jul-Aug 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Circular Structures In The Kurils Japan and Russia have been wrangling over the Kuril Islands for years. The 56 islands in the group lie between Hokkaido and Kamchatka. With the Cold War over scientists have finally been able to visit these wild, inhospitable bits of real estate. On uninhabited Onekota, a team of American, Japanese, and Russian biologists, led by T. Pietsch, serendipitously came across the undisturbed remains of several large, circular structures. The largest measured 22 meters (72 feet) across the circular embankment ringing a sunken center -- apparently once a large dwelling -- and much like those of the ancient Ainu on Hokkaido. The Ainu, it seems, had colonized the Kurils in bygone days. The implications are far-reaching, for the Ainu were once a seafaring people with Caucasian physiological characteristics. It is only a couple hundred miles from the Kurils to the Aleutians and a foothold on North America. The speculation is that the Ainu could well have bypassed the vaunted Bering Land Bridge 10,000 years ago and continued pushing south along the North American coast. (Holden, Constance; "Possible Ainu Site Creates Buzz," Science, 284:583, 1999.) Comment. Continuing our tour south along American coast, we encounter the remains of Kennewick Man in Washington State with his Caucasian features. (SF#109) Could he have been a far-wandering Ainu? The Ainu of ...

Science Frontiers ONLINE No. 122: Mar-Apr 1999 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Earth Hums More Loudly In The Afternoons It has been known for almost a century that large earthquakes set the earth to ringing like a bell. In SF#118, we reported that the planet also "hums" when there have been no earthquakes. Just what forces stimulate this seismic humming of the earth-as-a -whole is still a matter of conjecture. Actually, "hum" is a poor choice of words. The period of these vibrations ranges from 3 to 8 minutes, which puts them in the range of infrasound. Recently, N. Suda of Nagoya University has found a clue suggesting that thunderstorms may excite these very-lowfrequency vibrations. Suda and his colleagues analyzed the seismic records at four seismically quiet locations around the globe and discovered that the hum is loudest between noon and 8 PM local time. The quietest period is from midnight to 6 AM. These are the same time frames when thunderstorms are most active and quiet. It's circumstantial evidence, but it makes sense. (Kerr, Richard A.; "Earth Seems to Hum along with the Wind," Science, 283:321, 1999.) Comment. Infrasound in the atmosphere may originate from storms thousands of miles away and from strong winds blowing across mountain crests. It appears that the earth is an immense, spherical aeolian harp!
