Global warming could lead to a greener Greenland

Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years.

Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global Atmospheric Modelling (CGAM) at the University of Reading and the Met Office Hadley Centre, has estimated that Greenland is likely to pass a threshold of w

Time-reversal acoustics research promises medical breakthroughs

Scientists have not yet found a way to actually make time run backward, but in the cutting-edge world of recent acoustics research, they have shown a way to make sound waves run backward in a kind of ultra-focused reverse echo. By the technology known as time-reversal acoustics, sound waves – in exact reverse order from the original sound – echo directly and very precisely back to their source point.

The technology promises a wide array of applications, including medical applications such a

More than 300 critically endangered species completely unprotected, new study shows

Analysis of 11,633 species published in ’Nature’ underscores urgent need for major shift in conservation strategies

At least 300 Critically Endangered (CR) – as well as at least 237 Endangered (EN) and 267 Vulnerable (VU) – bird, mammal, turtle and amphibian species have no protection in any part of their ranges, according to the most comprehensive peer-reviewed analysis of its kind. The findings appear in the current issue of the journal Nature.

Loggerhead sea turtles nesting earlier due to warmer ocean temperatures

Loggerheads along Florida’s Atlantic coast are laying eggs 10 days earlier than 15 years ago, UCF research shows

Loggerhead sea turtles along Florida’s Atlantic coast are laying their eggs about 10 days earlier than they did 15 years ago, a change that a University of Central Florida researcher believes was caused by global warming.

John Weishampel, an associate professor of biology, found that as the near-shore ocean temperatures increased by nearly 1.5 degrees Fa

Here there be data: Mapping the landscape of science

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

Internet2 may change the way scientists conduct research

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
