The Hubble Space Telescope recently photographed Mars when the planet was nearly totally shrouded by high cirrus clouds. Mars is now cloudier than it has been for years. The reason for this is that the planet's average temperature has fallen by almost 20 C. What little water vapor exists in the atmosphere freezes out into cirrus clouds.

Our climate, atmospheric oxygen level, ocean composition, and similar vital conditions are kept livable by life's waste products, such as the oxygen emissions of plants. That something like Gaia is required is seen in the extreme disequilibrium of the earth's atmosphere compared to the near-equilibrium of the atmospheres of apparently lifeless Venus and Mars. For example, our atmosphere's 21% oxygen, a highly reactive gas, is many orders of magnitude higher than one would expect on a lifeless planet. Furthermore, life-friendly conditions have been maintained for billions of years despite large changes in the sun's output and the traumas of asteroid impacts. T. ... .

Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it is a tangled bank!

Happily, the hammerheads were not aggressive when so occupied and could be approached closely. They swam pointed in roughly the same direction, maintaining about the same spacing through the groups, which sometimes numbered 100 or more. They did not feed, mate, or do anything collectively; but once in a while an individual would suddenly engage ...

Apparently organic matter in the vicinity of the vent is thermally converted into oil, or at least something that, like wine, matures into something useful. (Simoneit, Bernd R.T ., and Lonsdale, Peter F.; "Hydrothermal Petroleum in Mineralized Mounds at the Seabed of Guayman Basin," Nature, 295:198, 1982.) Comment. The recently discovered hydrothermal vents are only the external manifestations of what must be extensive chemical factories beneath the crust. ...

... All Issues This Issue Sourcebook Project Sourcebook Subjects How A Fly Hears What A Cricket Hears As we all know, male crickets chirp long and loud for mates from spring until fall. That many males are successful in attracting females is obvious from this insect's population levels. Some of the singing males, however, attract parasitic flies that home in on their songs and deposit their maggots on or near them. Within 10 days, these singers are silent -- they have been consumed by the maggots. The really interesting part of this tale involves the hearing organs of the crickets and flies. Normally, they are radically different in design and frequency of operation. Crickets usually sing at frequencies above 3 kilohertz, and their ears are attuned to these high frequencies. The usual fly, on ...

A symbol-by-symbol comparison with the famous Grave Creek Stone reveals that both are inscribed with the same message, probably in a Semetic language. Barry Fell renders the message thus: "Tumulus in honor of Tadach. His wife caused this engraved tile to be inscribed." Why would anyone wish to make a second copy of such a message? The Grave Creek Stone was associated with a burial in West Virginia. Could there have been two Tadachs? Are either or both hoaxes? (Buchanan, Donal; ...
