For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks […]

New study reveals Some animals need extremely little oxygen
February 23rd, 2014 
Riffin One of science’s strongest dogmas is that complex life on Earth could only evolve when oxygen levels in the atmosphere rose to close to modern levels. But now studies of a small sea sponge fished out of a Danish fjord shows that complex life does not need high levels of oxygen in order to live […]
30 million years old bone-eating worms found
February 21st, 2014 Riffin An international team of scientists led by the paleontologist Steffen Kiel at the University of Kiel, Germany, found the first fossil boreholes of the worm Osedax that consumes whale bones on the deep-sea floor. They conclude that “boneworms” are at least 30 Million years old. This result was published in the current issue of the […]

basin may distorts the seismic radiation pattern
February 17th, 2014 Riffin Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin, according to two studies published by the Bulletin of the Seismological Society of America (BSSA). The basin will have the […]
Connection between color and physiology of dinosaurs revealed
February 16th, 2014 Riffin New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to its origin. In a survey comparing the hair, skin, fuzz and feathers of living terrestrial vertebrates and fossil specimens, a research team from […]
Jaw dropping: Scientists reveal how vertebrates came to have a face
February 14th, 2014 Riffin A team of French and Swedish researchers have presented new fossil evidence for the origin of one of the most important and emotionally significant parts of our anatomy: the face. Using micron resolution X-ray imaging, they show how a series of fossils, with a 410 million year old armoured fish called Romundina at its centre, […]
Terrestrial Origin of Viviparity in Mesozoic Marine Reptiles Indicated by Early Triassic Embryonic Fossils
February 13th, 2014 Riffin Viviparity in Mesozoic marine reptiles has traditionally been considered an aquatic adaptation. We report a new fossil specimen that strongly contradicts this traditional interpretation. The new specimen contains the oldest fossil embryos of Mesozoic marine reptile that are about 10 million years older than previous such records. The fossil belongs to Chaohusaurus (Reptilia, Ichthyopterygia), which […]
CALGARY – A new fossil site in Canada
February 11th, 2014 Riffin CALGARY – A new fossil site discovered in Kootenay National Park may be one of the world’s most important, according to researchers. A century after the discovery of Yoho National Park’s 505 million-year-old Burgess Shale, officials say a new fossil site has been located just 42 kilometres away. The new Marble Canyon fossil bed was […]
Is there an ocean beneath our feet? Ocean water may reach upper mantle through deep sea faults
February 10th, 2014 Riffin Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from Earth’s oceans to the upper mantle than previously thought. Water is carried mantle by deep sea fault zones which penetrate the oceanic plate as it bends into the subduction zone. Subduction, where an oceanic […]
