The remnants of a new 30-foot-long dinosaur discovered along the banks of Rio Colorado in Argentina may help to unravel how birds evolved their unusual breathing system. Palaeontologists led by the University of Chicago's Paul Sereno, a National Geographic Explorer-in-Residence, published their discovery 29 September in the online journal Public Library of Science ONE. Joining Sereno to announce the discovery at a news conference in Mendoza, Argentina, were Ricardo Martinez and Oscar Alcober, both of the Universidad Nacional de San Juan, Argentina…
NASA's Phoenix spacecraft has detected snow falling from Martian clouds. Lander's soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth. A laser instrument designed to gather knowledge of how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometres (2.5 miles) above the spacecraft's landing site. Data show the snow vaporising before reaching the ground…

More plant species grow in German towns and cities than in the countryside, but those in towns and cities are more closely related and are often functionally similar This makes urban ecosystems more susceptible to environmental impacts This is the finding of ecologists at the Helmholtz Centre for Environmental Research (UFZ) who evaluated 14 million entries in the German national FLORKART database, which has been built up by several thousand volunteers over the past few years…
Scientists may have discovered the relative of a freakishly behaving exploding star once thought to be the only one of its kind. For more than two decades, astronomers have intensively studied supernova 1987A, an exploding star that had behaved like no other. Instead of growing dimmer with time, 1987A has grown brighter at X-ray and radio wavelengths. A team of astronomers that includes the University of Chicago's Vikram Dwarkadas is asking if supernova 1996cr, discovered by Columbia University's Franz Bauer, is actually the 'wild cousin' of supernova 1987A…
Bedrock in Canada more than 4 billion years old may be the oldest known section of the Earth's early crust. Scientists at the Carnegie Institution of Washington and McGill University in Montreal used geochemical methods to obtain an age of 4.28 billion years for samples of the rock, making it 250 million years more ancient than any previously discovered rocks. The findings, which offer scientists clues to earliest stages of our planet's evolution, are published in this week's issue of the journal Science…
