Fire and ice: Mars images reveal recent volcanic and glacial activity
Mars isn't as sleepy as scientists suspected. An international research team, which includes Brown University planetary geologist James Head, has found evidence of recent glacial movement and volcanic eruptions in 3-D images from the Mars Express mission. The team's latest work, laid out in three Nature papers, also includes evidence of a frozen sea close to the equator. These and other Mars Express findings are stoking debate about the possibility of life on the Red Planet.

Fossil records show biodiversity comes and goes
A detailed and extensive new analysis of the fossil records of marine animals over the past 542 million years has yielded a stunning surprise. Biodiversity appears to rise and fall in mysterious cycles of 62 million years for which science has no satisfactory explanation. The analysis, performed by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, has withstood thorough testing so that confidence in the results is above 99-percent.

Survey finds silver contamination in North Pacific waters
The highest levels of silver contamination ever observed in the open ocean turned up in samples collected during a survey of the North Pacific in 2002. Researchers measured silver concentrations 50 times greater than the natural background level. Though still well below levels that would be toxic to marine life, this contamination of what had been considered relatively pristine waters highlights the increasingly global impact of industrial emissions from Asia, the researchers said.

Domesticated pig's wild origin mapped
Scientists from the Uppsala University and the Swedish University for Agricultural Sciences worked together to map the wild origins of the domesticated pig. The findings show that the wild boar was domesticated several times in different parts of Europe and Asia. The study is being presented in today's issue of the scientific journal Science.
