Experts say scrape-digging was a part of dinosaur courtship ritual
PARIS –Dinosaurs engaged in showy displays to attract mates 100 million years ago by clawing huge troughs in the ground with their feet, according to a new study.Scientists have long speculated that theropods — which included mega-carnivores like T. Rex and more nimble dinos that eventually evolved into birds — engaged in courtship rituals of some kind.One of the main drivers of evolution is sexual selection, in which males compete for the attention and affections of potential partners.But in th..>> view originalGreet the 'Anthropocene': five signs Earth's geology has entered a man-made epoch
Coal's origins date back to the Carboniferous Period 350million years ago. Dinosaurs roamed Earth until a meteor brought an end to their Cretaceous Period 66million years ago. Civilisation grew up in the Holocene, which started only 11 700 years ago.Now, these researchers argue, human industry and population have created the Anthropocene, or human epoch. They argue that we have, over the past 75 years or so, installed a new operating system for our 4.5billion-year-old planet.That's the subject o..>> view originalDistorted universities need a reality check

Antarctic scientists head to biological hotspot studying climate change in Southern OceanPostedJanuary 10, 2016 15:35:28 For the first time since Sir Douglas Mawson's Antarctic expeditions in the 1920s and 1930s, scientists will be conducting climate studies in the area known as the Kerguelen Plateau, in the Southern Ocean.The Kerguelen Plateau, hundreds of kilometres north of Mawson Station, is one of only three lines of longitude where the Antarctic Circumpolar Current flows across the Ant..>> view originalScientists propose a device that can create detectable gravitational field
By:PTI| London |Published:January 10, 2016 3:17 pmAlthough this experiment would require major resources, it could be used to test Einstein’s theory of general relativity. (Source: NASA)Scientists have proposed a revolutionary device which they say could create detectable gravitational field, an advance that may transform physics and shake up Einstein’s theory of general relativity.Until now, a scientific advance like this was a dream of science fiction, but it could open up many new application..>> view originalAustralia House water from 900 year old London well 'better than tap water'

The origins of our Milky Way galaxy are now much clearer. Using a revolutionary “growth-chart,” scientists led by Melissa Ness of the Max Planck Institute for Astronomy in Heidelberg, Germany, discovered how our own Milky Way galaxy grew into what it is now.They accomplished this by charting the ages of 70,000 stars and used that data to mock up a map for how the galaxy expanded and grew,Phys.orgstated.Astronomers create 3D map showing age of stars across Milky Wayhttps://t.co/CIwcQD0txL(via@jjb..>> view original
