Remote ‘marine deserts’ in the Atlantic Ocean could provide scientists with valuable clues to understanding climate change.

A research team led by the Plymouth Marine Laboratory will shortly set sail from the Falkland Islands, for the start of an expedition to study the interaction between tiny floating marine organisms (plankton) and the atmosphere. By monitoring the plankton and the influence of changing climate on its growth, they hope to discover whether the plankton act as a so

Long-debated, a firm answer is now on the horizon

Earth’s magnetic field reverses every few thousand years at low latitudes and every 10,000 years at high latitudes, a geologist funded by the National Science Foundation (NSF) has concluded. Brad Clement of Florida International University published his findings in this week’s issue of the journal Nature. The results are a major step forward in scientists’ understanding of how Earth’s magnetic field works.

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

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

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.

The “global gap analysis” au

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
