In ancient maps of the world, expanses of unknown territory might hold a warning to would-be explorers: Here there be monsters. For today’s explorers seeking to navigate and understand the world of science, the monsters are the untamed collections of data that inhabit a largely uncharted landscape.

The April 6, 2004, issue of the Proceedings of the National Academy of Sciences (PNAS) features nearly 20 articles by some of tomorrow’s mapmakers. Representing the computer, information and cog

When Dr. Robert Ballard went on a scientific expedition to Black Sea this past summer, he was able to take with him virtually any scientist or student who wanted to go. With the capability of Internet2 and a high bandwidth satellite link, scientists, for the first time, were able to work on the ocean floor from the comfort of their university laboratories.

In the April 6 issue of EOS, the weekly newspaper of the American Geophysical Union, Dr. Ballard, a University of Rhode Island geological

A novel method that uses bacteria to mine valuable minerals from the ocean has been developed. Nodules collected from the Indian Ocean seabed can be treated to extract scarce land-based minerals in an environmentally sound way, says research published in the Journal of Chemical Technology and Biotechnology.

Using the marine species Bacillus M1, Cobalt, Copper and Nickel can be extracted from the nodules at a near neutral pH and room temperature. In a single four-hour process, 45% Cobalt and

At present, we know of no worlds beyond our Earth where life exists. However, primitive organisms on our planet have evolved and adapted over billions of years, colonising the most inhospitable places.

Since life seems to gain a foothold in the most hostile environments, it seems distinctly possible that living organisms could exist in ice-covered oceans on worlds far from the Sun, according to Dr. David Rothery (Open University), who will be speaking today at the RAS National Astronomy Mee

If Washington state issues additional permits for water to be diverted from the Columbia River for farm irrigation, it should do so only under the condition that withdrawals can be stopped if river flows become critically low for endangered and threatened salmon, says a new report from the National Academies’ National Research Council. Salmon are at increased risk during periods of low flows and high water temperatures, conditions that are most likely to occur during the summer months when deman

Chemists at Ohio State University and their colleagues may have settled a 70-year-old scientific debate on the fundamental nature of ice.

A new statistical analysis mechanical theory has confirmed what some scientists only suspected before: that under the right conditions, molecules of water can freeze together in just the right way to form a perfect crystal. And once frozen, that ice can be manipulated by electric fields in the same way that magnets respond to magnetic fields.
