Allow an Aries his fixation
The greatest joy in life, for me, is the delight of discovery. Just as we are continually uncovering the rich complexity of this world, we now have a whole new planet being revealed. Just wait until we can operate with equal 'comfort' on Venus and the Jovian moons.
Martian Clays Tell Story of a Wet Past
Layers of clay-rich rock have been found in Mars' Mawrth Vallis, a potential landing site for future rovers.
This work, published in the August 8 issue of Science, suggests that abundant water was once present on Mars and that hydrothermal activity may have occurred.
The Mawrth Vallis outflow channel is a feature in Mars' northern highland region, a heavily cratered, ancient area of the Red Planet whose geology is a time capsule offering revelations to those who can read it. A team of researchers led by planetary scientist Janice Bishop of the SETI Institute has used the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) aboard the Mars Reconnaissance Orbiter (MRO) to examine infrared light reflected from clays situated in the many-kilometer wide channel. Mawrth Vallis resembles a dried-up, broad river valley through which water may have flowed.

Canary with scales?
There are very fundamental concerns which should be attracting our attention but we appear to be easily distracted by vacuousness. Reality will, in the long run, prevail but will it be too late?
Study: Earth's edible fish face extinction
A U.S. scientist predicts continued overfishing will lead to the extinction of the Earth's edible species of fish and affect other levels of the food chain.
Study: Earth's edible fish face extinction
A U.S. scientist predicts continued overfishing will lead to the extinction of the Earth's edible species of fish and affect other levels of the food chain. But Jeremy Jackson, a senior scientist at the Smithsonian Tropical Research Institute and the Scripps Institution of Oceanography, says just the enforcement of fishery regulations would help prevent such extinctions.
Jackson says certain steps, if taken immediately, might reverse the demise of the Earth's ocean species. Those measures include establishing marine reserves, eliminating subsidies for fertilizer use and limiting fossil fuel consumption.
In addition to the extinction of edible fish species, he said without the immediate implementation of ocean-protection measures, larger dead zones and toxic algal blooms may form along the coastal zones of all of the world's continents, increasing disease outbreaks and inhibiting vertical mixing of ocean waters.
