It eats detritus and plays a critical role in the breakdown and transport of carbon dioxid...

Ships create a noisy underwater The underwater world now has noise pollution similar to our neibourhood. The marine life gets affected in this noise. But the effects are not quite known.

Fossils of embryos The embryo fossils have been found dating back more than 500 million years ago. These fossils have been found in China and Siberia. They are preserved in the rocks. Using intense x-rays generated by particle accelerators, scientists now can peer into the fossils. The structure of the embryos have been found by synchrotron x-ray tomography microscopy. Scientists of the University of Bristol have found the fossil to be of Markeulia, a worm like animal. The sci...
