21 January 2008, for National Geographic News A rare volcanic eruption punched through Antarctica's ice sheet more than 2,000 years ago, scattering ash across the frozen landscape, a radar survey has revealed. The eruption was the biggest in Antarctica in the past 10,000 years, researchers estimate. |

14 January 2008, for National Geographic News The western part of Antarctica is shedding ice much faster today than it was just ten years ago, according to new satellite measurements. The measurements, which surveyed the coasts of nearly the entire continent, suggest that climate models underestimate how quickly Antarctica responds to ongoing global warming, said study co-author Jonathan Bamber of the University of Bristol in England. |

9 January 2008, for New Scientist Store shelves that know when they need restocking are one of many potential applications for a novel sensing foam developed by researchers in Europe. Shelves fitted with a thin layer of the foam can tell when products are out of stock, allowing a store to automatically monitor supply. And the foam could give other objects and surfaces sensing abilities, the researchers say. |

5 January 2008, for New Scientist Could a Wiki-style website speed up broadband access in the US? Because the Federal Communications Commission (FCC) releases little information on the availability and quality of existing services, it's hard to know where to start, although the US government has a mandate to increase access to broadband. |

19 December 2007, for New Scientist Bridges built from bamboo instead of steel could provide a cheaper, more environmentally sustainable engineering solution in China, a recent experiment suggests. A novel type of bridge with horizontal beams made from a bamboo composite proved strong enough to support even heavy trucks in tests. |

14 December 2007, for National Geographic News Earth has already crossed a number of climate change "tipping points" at which today's levels of greenhouse gases will cause additional large and rapid changes, a leading climate scientist said yesterday. But it's not too late to avoid much of the damage by curbing the use of fossil fuels such as oil and coal, climatologist James Hansen added during a presentation at the American Geophysical Union fall meeting in San Francisco. |

14 December 2007, for National Geographic News Arctic sea ice shrank drastically this summer, reaching a record low, largely because warm ocean currents ate away at the base of the ice sheet, new research says. Wind currents also played a key role, blowing sea ice south into the Atlantic Ocean, where the ice then melted, according to the research. |

6 December 2007, for New Scientist "Scrambled-up" polymers can kill bacteria, and may offer hope in beating problems of antibiotic drug resistance, suggests a new study. Researchers at the University of Wisconsin, in Madison, US, had been working on making molecules that mimic the short proteins known as "host-defence peptides". |

5 December 2007, for National Geographic News Magma-spewing volcanoes developed on the moon soon after its formation, according to a new study of a moon rock that fell to Earth. The findings will help researchers understand how planets develop in their early stages, the study authors say. |
