One of the problems facing nature conservationists is that they often have little idea what is being lost. The places where flora and fauna flourish are frequently remote, inaccessible or both.

In 2006 Mario Lebrato and Daniel Jones of the National Oceanography Centre in Southampton, England, were using a remotely operated deep-sea vehicle to study the sea floor near an oil pipeline off Cte dIvoire. What they found surprised them. It was a thaliacean graveyard. And its discovery throws into question the received wisdom about one important aspect of climate change, namely how much carbon from the atmosphere ends up at the bottom of the sea.

By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water. This could alter the pattern of both rain and snow in a warmer world.

The U.S. Environmental Protection Agency should examine whether combined exposures to chemicals known as phthalates could cause adverse health effects in humans, says a new report from the National Research Council. In addition, this analysis, called a cumulative risk assessment, should consider other chemicals that could potentially cause the same health effects as phthalates, instead of focusing on chemicals that are similar in structure, which is EPA's current practice. Furthermore, EPA should consider using the recommended approach for future cumulative risk assessments on other kinds of chemicals.

Researchers have discovered an unusual molecule that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. It's the unusual chemistry facilitated by this molecule, however, that will attract the most attention from scientists.
