Fiber-optic cables like the ones that bring television and Internet into millions of homes are now being used to measure how fast ice shelves in Antarctica are melting, according to new research. Researchers installed moorings containing fiber-optic cables hundreds of meters down into the McMurdo Ice Shelf in West Antarctica to collect temperature information about the base of the ice shelf, where the thick platform of floating ice meets the ocean. The sensors were able to measure mere [...]

A giant fossil, unearthed in the Sahara desert, has given scientists an unprecedented look at the largest-known carnivorous dinosaur: Spinosaurus.The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur. Scientists say the beast had flat, paddle-like feet and nostrils on top of its crocodilian head that would allow it to submerge with ease. The research is published in the journal Science. It had a long neck, a long [...]

It is located at the junction between the eastern and northern volcanic rift zones in the area close to where some scientists consider is the present-day location of the mantle hotspot beneath Iceland. The complex rifting means that there are probably sub-surface magmatic connections to both the Grimsvotn [...]
